2021-05-31	octave: udpate to 6.2.0	thor	1	-9/+5
	This updates octave and also gets some more recommened dependencies in, namely qrupdate and Mesalib (for osmesa) and gl2ps as well as the qscintilla editor. The glpk option is on by default again. This version of octave comes rather close to a standard build, with optimzied BLAS and GUI fluff. We are still missing SuiteSparse and SUNDIALS solvers, see https://octave.org/doc/v6.2.0/External-Packages.html PortAudio should also be considered, and LLVM be watched if that experimental JIT settles in. Upstream changes since 5.x: Summary of important user-visible changes for version 6.1.0 (2020-11-26): ------------------------------------------------------------------------ ### General improvements - The `intersect`, `setdiff`, `setxor`, `union`, and `unique` functions accept a new sorting option `"stable"` which will return output values in the same order as the input, rather than in ascending order. - Complex RESTful web services can now be accessed by the `webread` and `webwrite` functions alongside with the `weboptions` structure. One major feature is the support for cookies to enable RESTful communication with the web service. Additionally, the system web browser can be opened by the `web` function. - The `linspace` function now produces symmetrical sequences when the endpoints are symmetric. This is more intuitive and also compatible with recent changes made in Matlab R2019b. - The underlying algorithm of the `rand` function has been changed. For single precision outputs, the algorithm has been fixed so that it produces values strictly in the range (0, 1). Previously, it could occasionally generate the right endpoint value of 1 (See bug #41742). In addition, the new implementation uses a uniform interval between floating point values in the range (0, 1) rather than targeting a uniform density (# of random integers / length along real number line). - Numerical integration has been improved. The `quadv` function has been re-written so that it can compute integrands of periodic functions. At the same time, performance is better with ~3.5X fewer function evaluations required. A bug in `quadgk` that caused complex path integrals specified with `"Waypoints"` to occasionally be calculated in the opposite direction was fixed. - The `edit` function option `"editinplace"` now defaults to `true` and the option `"home"` now defaults to the empty matrix `[]`. Files will no longer be copied to the user's HOME directory for editing. The old behavior can be restored by setting `"editinplace"` to `false` and `"home"` to `"~/octave"`. - The `format` command supports two new options: `uppercase` and `lowercase` (default). With the default, print a lowercase 'e' for the exponent character in scientific notation and lowercase 'a-f' for the hex digits representing 10-15. With `uppercase`, print 'E' and 'A-F' instead. The previous uppercase formats, `E` and `G`, no longer control the case of the output. Additionally, the `format` command can be called with multiple options for controlling the format, spacing, and case in arbitrary order. For example: format long e uppercase loose Note, in the case of multiple competing format options the rightmost one is used, and, in case of an error, the previous format remains unchanged. - L-value references (e.g., increment (++), decrement (--), and all in-place assignment operators (+=, -=, =, /=, etc.)) are no longer allowed in anonymous functions. - New warnings have been added about questionable uses of the colon ':' range operator. Each has a new warning ID so that it can be disabled if desired. > `Octave:colon-complex-argument` : when any arg is complex > `Octave:colon-nonscalar-argument` : when any arg is non-scalar - The `regexp` and related functions now correctly handle and require* strings in UTF-8 encoding. As with any other function that requires strings to be encoded in Octave's native encoding, you can use `native2unicode` to convert from your preferred locale. For example, the copyright symbol in UTF-8 is `native2unicode (169, "latin1")`. - The startup file `octaverc` can now be located in the platform dependent location for user local configuration files (e.g., ${XDG_CONFIG_HOME}/octave/octaverc on Unix-like operating systems or %APPDATA%\octave\octaverc on Windows). - `pkg describe` now lists dependencies and inverse dependencies (i.e., other installed packages that depend on the package in question). - `pkg test` now tests all functions in a package. - When unloading a package, `pkg` now checks if any remaining loaded packages depend on the one to be removed. If this is the case `pkg` aborts with an explanatory error message. This behavior can be overridden with the `-nodeps` option. - The command dbstop in CLASS at METHOD now works to set breakpoints in classdef constructors and methods. #### Graphics backend - The use of Qt4 for graphics and the GUI is deprecated in Octave version 6 and no further bug fixes will be made. Qt4 support will be removed completely in Octave version 7. - The `legend` function has been entirely rewritten. This fixes a number of historical bugs, and also implements new properties such as `"AutoUpdate"` and `"NumColumns"`. The gnuplot toolkit---which is no longer actively maintained---still uses the old legend function. - The `axis` function was updated which resolved 10 bugs affecting axes to which `"equal"` had been applied. - Graphic primitives now accept a color property value of `"none"` which is useful when a particular primitive needs to be hidden (for example, the Y-axis of an axes object with `"ycolor" = "none"`) without hiding the entire primitive `"visibility" = "off"`. - A new property `"FontSmoothing"` has been added to text and axes objects that controls whether anti-aliasing is used during the rendering of characters. The default is `"on"` which produces smooth, more visually appealing text. - The figure property `"windowscrollwheelfcn"`is now implemented. This makes it possible to provide a callback function to be executed when users manipulate the mouse wheel on a given figure. - The figure properties `"pointer"`, `"pointershapecdata"`, and `"pointershapehotspot"` are now implemented. This makes it possible to change the shape of the cursor (pointer in Matlab-speak) displayed in a plot window. - The figure property `"paperpositionmode"` now has the default `"auto"` rather than `"manual"`. This change is more intuitive and is Matlab compatible. - The appearance of patterned lines `"LineStyle" = ":"\|"--"\|"-."` has been improved for small widths (`"LineWidth"` less than 1.5 pixels) which is a common scenario. - Printing to EPS files now uses a tight bounding box (`"-tight"` argument to print) by default. This makes more sense for EPS files which are normally embedded within other documents, and is Matlab compatible. If necessary use the `"-loose"` option to reproduce figures as they appeared in previous versions of Octave. - The following print devices are no longer officially supported: cdr, corel, aifm, ill, cgm, hpgl, mf and dxf. A warning will be thrown when using those devices, and the code for supporting those formats will eventually be removed from a future version of Octave. - The placement of text subscripts and superscripts has been re-engineered and now produces visually attractive results similar to Latex. ### Matlab compatibility - The function `unique` now returns column index vectors for the second and third outputs. When duplicate values are present, the default index to return is now the `"first"` occurrence. The previous Octave behavior, or Matlab behavior from releases prior to R2012b, can be obtained by using the `"legacy"` flag. - The function `setdiff` with the `"rows"` argument now returns Matlab compatible results. The previous Octave behavior, or Matlab behavior from releases prior to R2012b, can be obtained by using the `"legacy"` flag. - The functions `intersect`, `setxor`, and `union` now accept a `"legacy"` flag which changes the index values (second and third outputs) as well as the orientation of all outputs to match Matlab releases prior to R2012b. - The function `streamtube` is Matlab compatible and plots tubes along streamlines which are scaled by the vector field divergence. The Octave-only extension `ostreamtube` can be used to visualize the flow expansion and contraction of the vector field due to the local crossflow divergence. - The interpreter now supports handles to nested functions. - The graphics properties `"LineWidth"` and `"MarkerSize"` are now measured in points, not pixels. Compared to previous versions of Octave, some lines and markers will appear 4/3 larger. - The meta.class property "SuperClassList" has been renamed "Superclasslist" for Matlab compatibility. The original name will exist as an alias until Octave version 8.1. - Inline functions created by the function `inline` are now of type "inline" when interrogated with the `class` function. In previous versions of Octave, the class returned was "function_handle". This change is Matlab compatible. Inline functions are deprecated in both Matlab and Octave and support may eventually be removed. Anonymous functions can be used to replace all instances of inline functions. - The function `javaaddpath` now prepends new directories to the existing dynamic classpath by default. To append them instead, use the new `"-end"` argument. Multiple directories may now be specified in a cell array of strings. - An undocumented function `gui_mainfcn` has been added, for compatibility with figures created with Matlab's GUIDE. - Several validator functions of type `mustBe` have been added. See the list of new functions below. ### Alphabetical list of new functions added in Octave 6 `auto_repeat_debug_command` * `commandhistory` * `commandwindow` * `filebrowser` * `is_same_file` * `lightangle` * `mustBeFinite` * `mustBeGreaterThan` * `mustBeGreaterThanOrEqual` * `mustBeInteger` * `mustBeLessThan` * `mustBeLessThanOrEqual` * `mustBeMember` * `mustBeNegative` * `mustBeNonempty` * `mustBeNonNan` * `mustBeNonnegative` * `mustBeNonpositive` * `mustBeNonsparse` * `mustBeNonzero` * `mustBeNumeric` * `mustBeNumericOrLogical` * `mustBePositive` * `mustBeReal` * `namedargs2cell` * `newline` * `ode23s` * `ostreamtube` * `rescale` * `rotx` * `roty` * `rotz` * `stream2` * `stream3` * `streamline` * `streamtube` * `uisetfont` * `verLessThan` * `web` * `weboptions` * `webread` * `webwrite` * `workspace` ### Deprecated functions and properties The following functions and properties have been deprecated in Octave 6 and will be removed from Octave 8 (or whatever version is the second major release after 6): - Functions Function \| Replacement -----------------------\|------------------ `runtests` \| `oruntests` - Properties Object \| Property \| Value -----------------\|---------------\|------------ \| \| - The environment variable used by `mkoctfile` for linker flags is now `LDFLAGS` rather than `LFLAGS`. `LFLAGS` is deprecated, and a warning is emitted if it is used, but it will continue to work. ### Removed functions and properties The following functions and properties were deprecated in Octave 4.4 and have been removed from Octave 6. - Functions Function \| Replacement ---------------------\|------------------ `chop` \| `sprintf` for visual results `desktop` \| `isguirunning` `tmpnam` \| `tempname` `toascii` \| `double` `java2mat` \| `__java2mat__` - Properties Object \| Property \| Value ---------------------\|---------------------------\|----------------------- `annotation` \| `edgecolor ("rectangle")` \| `axes` \| `drawmode` \| `figure` \| `doublebuffer` \| \| `mincolormap` \| \| `wvisual` \| \| `wvisualmode` \| \| `xdisplay` \| \| `xvisual` \| \| `xvisualmode` \| `line` \| `interpreter` \| `patch` \| `interpreter` \| `surface` \| `interpreter` \| `text` \| `fontweight` \| `"demi"` and `"light"` `uibuttongroup` \| `fontweight` \| `"demi"` and `"light"` `uicontrol` \| `fontweight` \| `"demi"` and `"light"` `uipanel` \| `fontweight` \| `"demi"` and `"light"` `uitable` \| `fontweight` \| `"demi"` and `"light"`
2018-08-12	Octave: update to 4.4.1	maya	1	-5/+5
	Remove hack that had a high chance of resulting in a dysfunctional package qttools can't be a build dependency because we link against something in it. XXX pkgsrc claims this package has work directory references Summary of important user-visible changes for version 4.4 (2018-04-30): ---------------------------------------------------------------------- A graphical Variable Editor has been added to the GUI interface. It uses a spreadsheet-like interface for quick, intuitive editing of variables. The Variable Editor is launched by double-clicking on a variable name in the Workspace Window or by typing "openvar VARIABLE_NAME" in the Command Window. On systems with 64-bit pointers, --enable-64 is now the default and Octave always uses 64-bit indexing. However, if the configure script determines that the BLAS library uses 32-bit integers, then operations using the following libraries are limited to arrays with dimensions that are smaller than 2^31 elements: BLAS LAPACK QRUPDATE SuiteSparse ARPACK Additionally, the following libraries use "int" internally, so maximum problem sizes are always limited: glpk Qhull The octave command no longer starts the GUI by default. Most users starting Octave from a shell were expecting the command line interface, and desktop launchers already required the `--force-gui' option. With this change, desktop launchers should be modified to use the new option `--gui'. The previous `--force-gui' option will continue to work, and maps to `--gui', but it will be removed in Octave 6. A known bug in Qt (https://bugreports.qt.io/browse/QTBUG-55357) is addressed by limiting GUI sub-panel relocation capabilities for Qt versions in the range >= 5.6.1 and < 5.7.1. However, this may not thoroughly avoid issues on all platforms. A new container data type--containers.Map--is available. Map is a key/value storage container (a.k.a, a hash) that efficiently allows storing and retrieving values by name, rather than by position which is how arrays work. The bareword "import" is now recognized in scripts and functions. However, the functionality to import functions and classes from other namespaces into the local scope has not yet been implemented. Attempting to use "import" will provoke an error message. hex2num and num2hex now work for integer and char types and num2hex may optionally return a cell array of strings instead of a character array. If given a cell array of strings, hex2num now returns a numeric array of the same size as the input cell array. Previously, hex2num would accept a cell array of strings of arbitrary dimension but would always return a column vector. New special functions cosint, sinint, and gammaincinv have been added. ** Special functions in Octave have been rewritten for larger input domains, better accuracy, and additional options. * gammainc now accepts negative real values for X. * improved accuracy for gammainc, betainc, betaincinv, expint. * gammainc has new options "scaledlower" and "scaledupper". * betainc, betaincinv have new option "upper". The "names" option used in regular expressions now returns a struct array, rather than a struct with a cell array for each field. This change was made for Matlab compatibility. The quadcc function now uses both absolute tolerance and relative tolerance to determine the stopping criteria for an integration. To be compatible with other quadXXX functions, such as quadgk, the calling syntax has changed to quadcc (f, a, b, [AbsTol, [RelTol]]) To update existing code, change instances of RelTol to [0, RelTol]. quadcc (f, a, b, tol) => quadcc (f, a, b, [0, tol]) A warning that a single tolerance input is now interpreted as an absolute tolerance will be issued in Octave versions 4.4 and 5, after which it will be removed. The warning has ID "Octave:quadcc:RelTol-conversion" and can be disabled with warning ("off", "Octave:quadcc:RelTol-conversion") The qr function now returns a standard factorization unless explicitly instructed to perform an economy factorization by using a final argument of 0. The Qt graphics toolkit now supports offscreen printing without osmesa if Octave was built with Qt >= 5.1. The built-in pager for display of large data is now disabled by default. To re-enable it for every Octave session add the following to your .octaverc file: more on; The FLTK toolkit is no longer prioritized for development. The number of Octave Maintainers is too small to support three different graphic toolkits. New development will target the Qt toolkit. While no longer prioritized, the FLTK toolkit is not deprecated and there is no schedule for its removal. The graphic object property "PickableParts" has been implemented which controls whether an object can accept mouse clicks. The graphic object property "Interruptible" has been fully implemented which controls whether a running callback function can be interrupted by another callback function. The graphic object property "HitTest" has been updated to be fully compatible with Matlab. Text objects now implement the properties "BackgroundColor", "EdgeColor", "LineStyle", "LineWidth", and "Margin". An initial implementation of alpha transparency has been made for patch and surface objects. Printing to svg and pdf is supported. ishandle now returns true for both graphics handle objects and Java objects. The latter change was made for Matlab compatibility. Use ishghandle or isgraphics if it is important not to include Java objects. The pkg command now accepts a URL as an argument, allowing a valid Octave package to be installed from any remote host with one command, for example pkg install https://example.org/download/example-package.tar.gz The following statistical functions have been moved from core Octave to the statistics package available from Octave Forge.

Use the property "color" instead. The header file oct-alloc.h has been removed along with the macros that it defined (DECLARE_OCTAVE_ALLOCATOR, DEFINE_OCTAVE_ALLOCATOR, and DEFINE_OCTAVE_ALLOCATOR2).

2016-11-19	Octave: update to 4.2.0	maya	1	-4/+5
	pkgsrc changes: removed all patches to do with qt5 support, upstream code does it now. blindly moved some patches that were replacing INSTALL_PROGRAM to INSTALL_LIB as the build changed. added patch replacing struct tm_zone with timezone_t to accommodate for missing type in NetBSD - same as libgnu does. ok adam Summary of important user-visible changes for version 4.2: --------------------------------------------------------- The parser has been extended to accept, but ignore, underscore characters in numbers. This facilitates writing more legible code by using '_' as a thousands separator or to group nibbles into bytes in hex constants. Examples: 1_000_000 == 1e6 or 0xDE_AD_BE_EF The parser has been extended to understand binary numbers which begin with the prefix '0b' or '0B'. The value returned is Octave's default numeric class of double, not at unsigned integer class. Therefore numbers greater than flintmax, i.e., 2^53, will lose some precision. Examples: 0b101 == 5 or 0B1100_0001 == 0xC1 gnuplot 4.4 is now the minimum version supported by Octave. The default set of colors used to plot lines has been updated to be compatible with Matlab's new default color scheme. The line plot color scheme can be set with the axes property "ColorOrder". The default colormap is now set to "viridis" which is also the default colormap in matplotlib. This new colormap fixes some of the main issues with the old default colormap "jet" such as its bad "luminance profile" and is also more similar to Matlab's new default colormap "parula". The colormap function no longer supports the input argument "list" to show built-in colormaps. Use "help colormap" to find the built-in colormaps. ** The graphics command "hold on" now ensures that each new plot added to an existing plot has a different color or linestyle according to the "ColorOrder" and/or "LineStyleOrder" properties. This is equivalent to the old command "hold all" and was made for Matlab compatibility. Existing code may produce differently colored plots if it did not specify the color for a plot and relied on each new plot having the default first color in the "ColorOrder" property. When starting, Octave now looks in the function path for a file startup.m and executes any commands found there. This change was made to accommodate Matlab users. Octave has it's own configuration system based on the file .octaverc which is preferred. Octal ('\NNN') and hex ('\xNN') escape sequences in single quoted strings are now interpreted by the function do_string_escapes(). The printf family of functions now supports octal and hex escape sequences in single-quoted strings for Matlab compatibility. * Special octal and hex escape sequences for the pattern and replacement strings in regular expressions are now interpreted for Matlab compatibility. octal: '\oNNN' or '\o{NNN}' hex : '\xNN' or '\x{NN}' Unknown escape sequences in the replacement string for regexprep are now substituted with their unescaped version and no warning is emitted. This change was made for Matlab compatibility. Example: regexprep ('a', 'a', 'x\yz') => 'xyz' mkfifo now interprets the MODE argument as an octal, not decimal, integer. This is consistent with the equivalent shell command. linspace now returns an empty matrix if the number of requested points is 0 or a negative number. This change was made to be compatible with Matlab releases newer than 2011. In addition, Octave no longer supports matrix inputs for A or B. The cov function now returns the complex conjugate of the result from previous versions of Octave. This change was made for compatibility with Matlab. condest now works with a normest1 compatible syntax. The griddata function no longer plots the interpolated mesh if no output argument is requested, instead the vector or array of interpolated values is always returned for Matlab compatibility. The new function "light" and the corresponding graphics object provide light and shadow effects for patch and surface objects. The surfnorm function now returns unnormalized (magnitude != 1) normal vectors for compatibility with Matlab. The normal vectors returned from isonormals have been reversed to point towards smaller values for compatibility with Matlab. The quadl function now uses an absolute, rather than relative, tolerance for Matlab compatibility. The default tolerance is 1e-6 which may result in lower precision results than previous versions of Octave which used eps as the relative tolerance. The quadl function has also been extended to return a second output with the total number of function evaluations. The textscan function is now built-in and is much faster and much more Matlab-compatible than the previous m-file version. Dialog boxes--errordlg, helpdlg, inputdlg, listdlg, msgbox, questdlg, and warndlg--now exclusively use Qt for rendering. Java based versions have been removed. The axes properties "TitleFontSizeMultiplier" and "TitleFontWeight" are now implemented which control the default appearance of text created with title(). The axes property "LabelFontSizeMultiplier" is now implemented which controls the default appearance of text created with xlabel(), ylabel(), or zlabel(). The graphics property "box" for axes now defaults to "off". To obtain equivalent plots to previous versions of Octave use set (0, "DefaultAxesBox", "on"); in your .octaverc file. The graphics property "boxstyle" has been implemented. The default is "back" which draws only the back planes in a 3-D view. If the option is "full" then all planes are drawn. The graphics property "erasemode" has been hidden, and will eventually be removed. This property has also been removed from Matlab, and was never implemented in Octave. The graphics property "graphicssmoothing" for figures now controls whether anti-aliasing will be used for lines. The default is "on". The value "zero" for the axes properties "xaxislocation" and "yaxislocation" has been deprecated and will be removed from Octave 4.6. Use "origin" instead. The publish function allows easy publication of Octave script files in HTML or other formats, including figures and output created by this script. It comes with its counterpart grabcode, which lets one literally grab the HTML published code from a remote website, for example. The value of the MEX variable TrapFlag now defaults to 0, which will cause Octave to abort execution of a MEX file and return to the prompt if an error is encountered in mexCallMATLAB. The MEX API now includes the function mexCallMATLABWithTrap. This function will not abort if an error occurs during mexCallMATLAB, but instead will return execution to the MEX function for error handling. The MEX API functions for input validation that begin with "mxIs" (e.g., mxIsDouble, mxIsEmpty, etc.) now return type bool rather than type int. The functions mxAssert and mxAssertS for checking assertions have been added. In order to avoid a performance penalty they are only compiled in to debug versions of a MEX file, i.e., that are produced when the '-g' option is given to mex or mkoctfile. Other new MEX API functions include mexEvalStringWithTrap, mxIsScalar, mxCreateUninitNumericArray, mxCreateUninitNumericMatrix. Other new functions added in 4.2: audioformats camlight condeig deg2rad dialog evalc hash im2double isocaps lighting localfunctions material normest1 ode23 ode45 odeget odeplot odeset padecoef profexport psi rad2deg reducepatch reducevolume smooth3 uibuttongroup Deprecated functions.

Now the error and print_usage functions throw an exception (octave::execution_exception) after displaying the error message. This makes the error and print_usage functions in C++ work more like the corresponding functions in the scripting language. The default error handlers in liboctave have been updated to use exceptions. After displaying an error message they no longer return control to the calling program. The error handler function can be customized through the global variables "current_liboctave_error_handler" and "current_liboctave_error_with_id_handler". If a programmer has installed their own custom error handling routines when directly linking with liboctave then these must be updated to throw an exception and not return to the calling program. The system for common errors and warnings has been renamed from gripe_XXX to either err_XXX if error is called or warn_XXX if warning is called. The gripe_XXX functions are deprecated and will be removed in version 4.6. ** New configure option, --enable-address-sanitizer-flags, to build Octave with memory allocator checks (similar to those in valgrind) built in.

This updates octave and also gets some more recommened dependencies in, namely qrupdate and Mesalib (for osmesa) and gl2ps as well as the qscintilla editor. The glpk option is on by default again. This version of octave comes rather close to a standard build, with optimzied BLAS and GUI fluff. We are still missing SuiteSparse and SUNDIALS solvers, see https://octave.org/doc/v6.2.0/External-Packages.html PortAudio should also be considered, and LLVM be watched if that experimental JIT settles in. Upstream changes since 5.x: Summary of important user-visible changes for version 6.1.0 (2020-11-26): ------------------------------------------------------------------------ ### General improvements - The `intersect`, `setdiff`, `setxor`, `union`, and `unique` functions accept a new sorting option `"stable"` which will return output values in the same order as the input, rather than in ascending order. - Complex RESTful web services can now be accessed by the `webread` and `webwrite` functions alongside with the `weboptions` structure.

Previously, it could occasionally generate the right endpoint value of 1 (See bug #41742). In addition, the new implementation uses a uniform interval between floating point values in the range (0, 1) rather than targeting a uniform density (# of random integers / length along real number line). - Numerical integration has been improved. The `quadv` function has been re-written so that it can compute integrands of periodic functions. At the same time, performance is better with ~3.5X fewer function evaluations required. A bug in `quadgk` that caused complex path integrals specified with `"Waypoints"` to occasionally be calculated in the opposite direction was fixed. - The `edit` function option `"editinplace"` now defaults to `true` and the option `"home"` now defaults to the empty matrix `[]`. Files will no longer be copied to the user's HOME directory for editing. The old behavior can be restored by setting `"editinplace"` to `false` and `"home"` to `"~/octave"`. - The `format` command supports two new options: `uppercase` and `lowercase` (default). With the default, print a lowercase 'e' for the exponent character in scientific notation and lowercase 'a-f' for the hex digits representing 10-15. With `uppercase`, print 'E' and 'A-F' instead. The previous uppercase formats, `E` and `G`, no longer control the case of the output. Additionally, the `format` command can be called with multiple options for controlling the format, spacing, and case in arbitrary order. For example: format long e uppercase loose Note, in the case of multiple competing format options the rightmost one is used, and, in case of an error, the previous format remains unchanged. - L-value references (e.g., increment (++), decrement (--), and all in-place assignment operators (+=, -=, *=, /=, etc.)) are no longer allowed in anonymous functions. - New warnings have been added about questionable uses of the colon ':' range operator. Each has a new warning ID so that it can be disabled if desired. > `Octave:colon-complex-argument` : when any arg is complex > `Octave:colon-nonscalar-argument` : when any arg is non-scalar - The `regexp` and related functions now correctly handle and *require* strings in UTF-8 encoding. As with any other function that requires strings to be encoded in Octave's native encoding, you can use `native2unicode` to convert from your preferred locale. For example, the copyright symbol in UTF-8 is `native2unicode (169, "latin1")`. - The startup file `octaverc` can now be located in the platform dependent location for user local configuration files (e.g., ${XDG_CONFIG_HOME}/octave/octaverc on Unix-like operating systems or %APPDATA%\octave\octaverc on Windows). - `pkg describe` now lists dependencies and inverse dependencies (i.e., other installed packages that depend on the package in question). - `pkg test` now tests all functions in a package. - When unloading a package, `pkg` now checks if any remaining loaded packages depend on the one to be removed. If this is the case `pkg` aborts with an explanatory error message. This behavior can be overridden with the `-nodeps` option. - The command dbstop in CLASS at METHOD now works to set breakpoints in classdef constructors and methods. #### Graphics backend - The use of Qt4 for graphics and the GUI is deprecated in Octave version 6 and no further bug fixes will be made. Qt4 support will be removed completely in Octave version 7. - The `legend` function has been entirely rewritten. This fixes a number of historical bugs, and also implements new properties such as `"AutoUpdate"` and `"NumColumns"`. The gnuplot toolkit---which is no longer actively maintained---still uses the old legend function. - The `axis` function was updated which resolved 10 bugs affecting axes to which `"equal"` had been applied. - Graphic primitives now accept a color property value of `"none"` which is useful when a particular primitive needs to be hidden (for example, the Y-axis of an axes object with `"ycolor" = "none"`) without hiding the entire primitive `"visibility" = "off"`. - A new property `"FontSmoothing"` has been added to text and axes objects that controls whether anti-aliasing is used during the rendering of characters. The default is `"on"` which produces smooth, more visually appealing text. - The figure property `"windowscrollwheelfcn"`is now implemented. This makes it possible to provide a callback function to be executed when users manipulate the mouse wheel on a given figure. - The figure properties `"pointer"`, `"pointershapecdata"`, and `"pointershapehotspot"` are now implemented. This makes it possible to change the shape of the cursor (pointer in Matlab-speak) displayed in a plot window. - The figure property `"paperpositionmode"` now has the default `"auto"` rather than `"manual"`. This change is more intuitive and is Matlab compatible. - The appearance of patterned lines `"LineStyle" = ":"|"--"|"-."` has been improved for small widths (`"LineWidth"` less than 1.5 pixels) which is a common scenario. - Printing to EPS files now uses a tight bounding box (`"-tight"` argument to print) by default. This makes more sense for EPS files which are normally embedded within other documents, and is Matlab compatible. If necessary use the `"-loose"` option to reproduce figures as they appeared in previous versions of Octave. - The following print devices are no longer officially supported: cdr, corel, aifm, ill, cgm, hpgl, mf and dxf. A warning will be thrown when using those devices, and the code for supporting those formats will eventually be removed from a future version of Octave. - The placement of text subscripts and superscripts has been re-engineered and now produces visually attractive results similar to Latex. ### Matlab compatibility - The function `unique` now returns column index vectors for the second and third outputs. When duplicate values are present, the default index to return is now the `"first"` occurrence. The previous Octave behavior, or Matlab behavior from releases prior to R2012b, can be obtained by using the `"legacy"` flag. - The function `setdiff` with the `"rows"` argument now returns Matlab compatible results. The previous Octave behavior, or Matlab behavior from releases prior to R2012b, can be obtained by using the `"legacy"` flag. - The functions `intersect`, `setxor`, and `union` now accept a `"legacy"` flag which changes the index values (second and third outputs) as well as the orientation of all outputs to match Matlab releases prior to R2012b. - The function `streamtube` is Matlab compatible and plots tubes along streamlines which are scaled by the vector field divergence. The Octave-only extension `ostreamtube` can be used to visualize the flow expansion and contraction of the vector field due to the local crossflow divergence. - The interpreter now supports handles to nested functions. - The graphics properties `"LineWidth"` and `"MarkerSize"` are now measured in points, *not* pixels. Compared to previous versions of Octave, some lines and markers will appear 4/3 larger. - The meta.class property "SuperClassList" has been renamed "Superclasslist" for Matlab compatibility. The original name will exist as an alias until Octave version 8.1. - Inline functions created by the function `inline` are now of type "inline" when interrogated with the `class` function. In previous versions of Octave, the class returned was "function_handle". This change is Matlab compatible. Inline functions are deprecated in both Matlab and Octave and support may eventually be removed. Anonymous functions can be used to replace all instances of inline functions. - The function `javaaddpath` now prepends new directories to the existing dynamic classpath by default. To append them instead, use the new `"-end"` argument. Multiple directories may now be specified in a cell array of strings. - An undocumented function `gui_mainfcn` has been added, for compatibility with figures created with Matlab's GUIDE. - Several validator functions of type `mustBe*` have been added. See the list of new functions below. ### Alphabetical list of new functions added in Octave 6 * `auto_repeat_debug_command` * `commandhistory` * `commandwindow` * `filebrowser` * `is_same_file` * `lightangle` * `mustBeFinite` * `mustBeGreaterThan` * `mustBeGreaterThanOrEqual` * `mustBeInteger` * `mustBeLessThan` * `mustBeLessThanOrEqual` * `mustBeMember` * `mustBeNegative` * `mustBeNonempty` * `mustBeNonNan` * `mustBeNonnegative` * `mustBeNonpositive` * `mustBeNonsparse` * `mustBeNonzero` * `mustBeNumeric` * `mustBeNumericOrLogical` * `mustBePositive` * `mustBeReal` * `namedargs2cell` * `newline` * `ode23s` * `ostreamtube` * `rescale` * `rotx` * `roty` * `rotz` * `stream2` * `stream3` * `streamline` * `streamtube` * `uisetfont` * `verLessThan` * `web` * `weboptions` * `webread` * `webwrite` * `workspace` ### Deprecated functions and properties The following functions and properties have been deprecated in Octave 6 and will be removed from Octave 8 (or whatever version is the second major release after 6): - Functions Function | Replacement -----------------------|------------------ `runtests` | `oruntests` - Properties Object | Property | Value -----------------|---------------|------------ | | - The environment variable used by `mkoctfile` for linker flags is now `LDFLAGS` rather than `LFLAGS`. `LFLAGS` is deprecated, and a warning is emitted if it is used, but it will continue to work. ### Removed functions and properties The following functions and properties were deprecated in Octave 4.4 and have been removed from Octave 6. - Functions Function | Replacement ---------------------|------------------ `chop` | `sprintf` for visual results `desktop` | `isguirunning` `tmpnam` | `tempname` `toascii` | `double` `java2mat` | `__java2mat__` - Properties Object | Property | Value ---------------------|---------------------------|----------------------- `annotation` | `edgecolor ("rectangle")` | `axes` | `drawmode` | `figure` | `doublebuffer` | | `mincolormap` | | `wvisual` | | `wvisualmode` | | `xdisplay` | | `xvisual` | | `xvisualmode` | `line` | `interpreter` | `patch` | `interpreter` | `surface` | `interpreter` | `text` | `fontweight` | `"demi"` and `"light"` `uibuttongroup` | `fontweight` | `"demi"` and `"light"` `uicontrol` | `fontweight` | `"demi"` and `"light"` `uipanel` | `fontweight` | `"demi"` and `"light"` `uitable` | `fontweight` | `"demi"` and `"light"`

Remove hack that had a high chance of resulting in a dysfunctional package qttools can't be a build dependency because we link against something in it. XXX pkgsrc claims this package has work directory references Summary of important user-visible changes for version 4.4 (2018-04-30): ---------------------------------------------------------------------- ** A graphical Variable Editor has been added to the GUI interface. It uses a spreadsheet-like interface for quick, intuitive editing of variables. The Variable Editor is launched by double-clicking on a variable name in the Workspace Window or by typing "openvar VARIABLE_NAME" in the Command Window. ** On systems with 64-bit pointers, --enable-64 is now the default and Octave always uses 64-bit indexing. However, if the configure script determines that the BLAS library uses 32-bit integers, then operations using the following libraries are limited to arrays with dimensions that are smaller than 2^31 elements: BLAS LAPACK QRUPDATE SuiteSparse ARPACK Additionally, the following libraries use "int" internally, so maximum problem sizes are always limited: glpk Qhull ** The octave command no longer starts the GUI by default. Most users starting Octave from a shell were expecting the command line interface, and desktop launchers already required the `--force-gui' option. With this change, desktop launchers should be modified to use the new option `--gui'. The previous `--force-gui' option will continue to work, and maps to `--gui', but it will be removed in Octave 6. ** A known bug in Qt (https://bugreports.qt.io/browse/QTBUG-55357) is addressed by limiting GUI sub-panel relocation capabilities for Qt versions in the range >= 5.6.1 and < 5.7.1. However, this may not thoroughly avoid issues on all platforms. ** A new container data type--containers.Map--is available. Map is a key/value storage container (a.k.a, a hash) that efficiently allows storing and retrieving values by name, rather than by position which is how arrays work. ** The bareword "import" is now recognized in scripts and functions. However, the functionality to import functions and classes from other namespaces into the local scope has not yet been implemented. Attempting to use "import" will provoke an error message. ** hex2num and num2hex now work for integer and char types and num2hex may optionally return a cell array of strings instead of a character array. If given a cell array of strings, hex2num now returns a numeric array of the same size as the input cell array. Previously, hex2num would accept a cell array of strings of arbitrary dimension but would always return a column vector. ** New special functions cosint, sinint, and gammaincinv have been added. ** Special functions in Octave have been rewritten for larger input domains, better accuracy, and additional options. * gammainc now accepts negative real values for X. * improved accuracy for gammainc, betainc, betaincinv, expint. * gammainc has new options "scaledlower" and "scaledupper". * betainc, betaincinv have new option "upper". ** The "names" option used in regular expressions now returns a struct array, rather than a struct with a cell array for each field. This change was made for Matlab compatibility. ** The quadcc function now uses both absolute tolerance and relative tolerance to determine the stopping criteria for an integration. To be compatible with other quadXXX functions, such as quadgk, the calling syntax has changed to quadcc (f, a, b, [AbsTol, [RelTol]]) To update existing code, change instances of RelTol to [0, RelTol]. quadcc (f, a, b, tol) => quadcc (f, a, b, [0, tol]) A warning that a single tolerance input is now interpreted as an absolute tolerance will be issued in Octave versions 4.4 and 5, after which it will be removed. The warning has ID "Octave:quadcc:RelTol-conversion" and can be disabled with warning ("off", "Octave:quadcc:RelTol-conversion") ** The qr function now returns a standard factorization unless explicitly instructed to perform an economy factorization by using a final argument of 0. ** The Qt graphics toolkit now supports offscreen printing without osmesa if Octave was built with Qt >= 5.1. ** The built-in pager for display of large data is now disabled by default. To re-enable it for every Octave session add the following to your .octaverc file: more on; ** The FLTK toolkit is no longer prioritized for development. The number of Octave Maintainers is too small to support three different graphic toolkits. New development will target the Qt toolkit. While no longer prioritized, the FLTK toolkit is not deprecated and there is no schedule for its removal. ** The graphic object property "PickableParts" has been implemented which controls whether an object can accept mouse clicks. ** The graphic object property "Interruptible" has been fully implemented which controls whether a running callback function can be interrupted by another callback function. ** The graphic object property "HitTest" has been updated to be fully compatible with Matlab. ** Text objects now implement the properties "BackgroundColor", "EdgeColor", "LineStyle", "LineWidth", and "Margin". ** An initial implementation of alpha transparency has been made for patch and surface objects. Printing to svg and pdf is supported. ** ishandle now returns true for both graphics handle objects and Java objects. The latter change was made for Matlab compatibility. Use ishghandle or isgraphics if it is important not to include Java objects. ** The pkg command now accepts a URL as an argument, allowing a valid Octave package to be installed from any remote host with one command, for example pkg install https://example.org/download/example-package.tar.gz ** The following statistical functions have been moved from core Octave to the statistics package available from Octave Forge.

pkgsrc changes: removed all patches to do with qt5 support, upstream code does it now. blindly moved some patches that were replacing INSTALL_PROGRAM to INSTALL_LIB as the build changed. added patch replacing struct tm_zone with timezone_t to accommodate for missing type in NetBSD - same as libgnu does. ok adam Summary of important user-visible changes for version 4.2: --------------------------------------------------------- ** The parser has been extended to accept, but ignore, underscore characters in numbers. This facilitates writing more legible code by using '_' as a thousands separator or to group nibbles into bytes in hex constants. Examples: 1_000_000 == 1e6 or 0xDE_AD_BE_EF ** The parser has been extended to understand binary numbers which begin with the prefix '0b' or '0B'. The value returned is Octave's default numeric class of double, not at unsigned integer class. Therefore numbers greater than flintmax, i.e., 2^53, will lose some precision. Examples: 0b101 == 5 or 0B1100_0001 == 0xC1 ** gnuplot 4.4 is now the minimum version supported by Octave. ** The default set of colors used to plot lines has been updated to be compatible with Matlab's new default color scheme. The line plot color scheme can be set with the axes property "ColorOrder". ** The default colormap is now set to "viridis" which is also the default colormap in matplotlib. This new colormap fixes some of the main issues with the old default colormap "jet" such as its bad "luminance profile" and is also more similar to Matlab's new default colormap "parula". ** The colormap function no longer supports the input argument "list" to show built-in colormaps. Use "help colormap" to find the built-in colormaps. ** The graphics command "hold on" now ensures that each new plot added to an existing plot has a different color or linestyle according to the "ColorOrder" and/or "LineStyleOrder" properties. This is equivalent to the old command "hold all" and was made for Matlab compatibility. Existing code *may* produce differently colored plots if it did not specify the color for a plot and relied on each new plot having the default first color in the "ColorOrder" property. ** When starting, Octave now looks in the function path for a file startup.m and executes any commands found there. This change was made to accommodate Matlab users. Octave has it's own configuration system based on the file .octaverc which is preferred. ** Octal ('\NNN') and hex ('\xNN') escape sequences in single quoted strings are now interpreted by the function do_string_escapes(). The *printf family of functions now supports octal and hex escape sequences in single-quoted strings for Matlab compatibility. ** Special octal and hex escape sequences for the pattern and replacement strings in regular expressions are now interpreted for Matlab compatibility. octal: '\oNNN' or '\o{NNN}' hex : '\xNN' or '\x{NN}' ** Unknown escape sequences in the replacement string for regexprep are now substituted with their unescaped version and no warning is emitted. This change was made for Matlab compatibility. Example: regexprep ('a', 'a', 'x\yz') => 'xyz' ** mkfifo now interprets the MODE argument as an octal, not decimal, integer. This is consistent with the equivalent shell command. ** linspace now returns an empty matrix if the number of requested points is 0 or a negative number. This change was made to be compatible with Matlab releases newer than 2011. In addition, Octave no longer supports matrix inputs for A or B. ** The cov function now returns the complex conjugate of the result from previous versions of Octave. This change was made for compatibility with Matlab. ** condest now works with a normest1 compatible syntax. ** The griddata function no longer plots the interpolated mesh if no output argument is requested, instead the vector or array of interpolated values is always returned for Matlab compatibility. ** The new function "light" and the corresponding graphics object provide light and shadow effects for patch and surface objects. ** The surfnorm function now returns unnormalized (magnitude != 1) normal vectors for compatibility with Matlab. ** The normal vectors returned from isonormals have been reversed to point towards smaller values for compatibility with Matlab. ** The quadl function now uses an absolute, rather than relative, tolerance for Matlab compatibility. The default tolerance is 1e-6 which may result in lower precision results than previous versions of Octave which used eps as the relative tolerance. The quadl function has also been extended to return a second output with the total number of function evaluations. ** The textscan function is now built-in and is much faster and much more Matlab-compatible than the previous m-file version. ** Dialog boxes--errordlg, helpdlg, inputdlg, listdlg, msgbox, questdlg, and warndlg--now exclusively use Qt for rendering. Java based versions have been removed. ** The axes properties "TitleFontSizeMultiplier" and "TitleFontWeight" are now implemented which control the default appearance of text created with title(). The axes property "LabelFontSizeMultiplier" is now implemented which controls the default appearance of text created with xlabel(), ylabel(), or zlabel(). ** The graphics property "box" for axes now defaults to "off". To obtain equivalent plots to previous versions of Octave use set (0, "DefaultAxesBox", "on"); in your .octaverc file. ** The graphics property "boxstyle" has been implemented. The default is "back" which draws only the back planes in a 3-D view. If the option is "full" then all planes are drawn. ** The graphics property "erasemode" has been hidden, and will eventually be removed. This property has also been removed from Matlab, and was never implemented in Octave. ** The graphics property "graphicssmoothing" for figures now controls whether anti-aliasing will be used for lines. The default is "on". ** The value "zero" for the axes properties "xaxislocation" and "yaxislocation" has been deprecated and will be removed from Octave 4.6. Use "origin" instead. ** The publish function allows easy publication of Octave script files in HTML or other formats, including figures and output created by this script. It comes with its counterpart grabcode, which lets one literally grab the HTML published code from a remote website, for example. ** The value of the MEX variable TrapFlag now defaults to 0, which will cause Octave to abort execution of a MEX file and return to the prompt if an error is encountered in mexCallMATLAB. ** The MEX API now includes the function mexCallMATLABWithTrap. This function will not abort if an error occurs during mexCallMATLAB, but instead will return execution to the MEX function for error handling. ** The MEX API functions for input validation that begin with "mxIs" (e.g., mxIsDouble, mxIsEmpty, etc.) now return type bool rather than type int. ** The functions mxAssert and mxAssertS for checking assertions have been added. In order to avoid a performance penalty they are only compiled in to debug versions of a MEX file, i.e., that are produced when the '-g' option is given to mex or mkoctfile. ** Other new MEX API functions include mexEvalStringWithTrap, mxIsScalar, mxCreateUninitNumericArray, mxCreateUninitNumericMatrix. ** Other new functions added in 4.2: audioformats camlight condeig deg2rad dialog evalc hash im2double isocaps lighting localfunctions material normest1 ode23 ode45 odeget odeplot odeset padecoef profexport psi rad2deg reducepatch reducevolume smooth3 uibuttongroup ** Deprecated functions.

Now the error and print_usage functions throw an exception (octave::execution_exception) after displaying the error message. This makes the error and print_usage functions in C++ work more like the corresponding functions in the scripting language. ** The default error handlers in liboctave have been updated to use exceptions. After displaying an error message they no longer return control to the calling program. The error handler function can be customized through the global variables "current_liboctave_error_handler" and "current_liboctave_error_with_id_handler". If a programmer has installed their own custom error handling routines when directly linking with liboctave then these must be updated to throw an exception and not return to the calling program. ** The system for common errors and warnings has been renamed from gripe_XXX to either err_XXX if error is called or warn_XXX if warning is called. The gripe_XXX functions are deprecated and will be removed in version 4.6. ** New configure option, --enable-address-sanitizer-flags, to build Octave with memory allocator checks (similar to those in valgrind) built in.
