.Sh NAME
.Nm atf-config
.Nd queries static configuration information of ATF
.Sh SYNOPSIS
.Nm
.Op Fl t
.Op Ar var1 Op Ar .. varN
.Nm
.Fl h
.Sh DESCRIPTION
.Nm
is a utility that queries static configuration information of ATF.
Static configuration refers to all those values for settings that
were built into the ATF binaries at build time.
.Pp
In the first synopsis form,
.Nm
will print variable-value pairs for all built-in static variables if
no variable names are provided as arguments.
If any is provided, it will only print the variable-value pairs for
those variables.
The output of the utility does not use the
.Sq =
symbol to separate the variable name from its corresponding value in
an attempt to avoid sourcing the output in shell scripts or Makefiles.
If you need to do that, the
.Fl t
flag allows you to query the value of individual variables without any
surrounding text.
.Pp
In the second synopsis form,
.Nm
will print information about all supported options and their purpose.
.Pp
The following options are available:
.Bl -tag -width flag
.It Fl h
Shows a short summary of all available options and their purpose.
.It Fl t
Changes the output of the utility to show the variable values, one
per line, without the variable names.
.El
.Ss Static configuration variables
The following list describes all the variables that are part of ATF's
static configuration:
.Bl -tag -width atfXbuildXcppflagsXX
.It Va atf_arch
The architecture name detected by ATF.
This is derived from
.Va atf_machine
because it is a subset of it.
Given that this name might be misdetected, it is provided to the user
as a configuration variable so that he can fix its value temporarily
until a real fix is incorporated into mainstream sources.
.It Va atf_build_cc
The C compiler used by the ATF checks that provide build-time tests.
.It Va atf_build_cflags
The C compiler flags used by the ATF checks that provide build-time tests.
.It Va atf_build_cpp
The C/C++ preprocessor used by the ATF checks that provide build-time tests.
.It Va atf_build_cppflags
The C/C++ preprocessor flags used by the ATF checks that provide build-time
tests.
.It Va atf_build_cxx
The C++ compiler used by the ATF checks that provide build-time tests.
.It Va atf_build_cxxflags
The C++ compiler flags used by the ATF checks that provide build-time tests.
.It Va atf_confdir
The path to the directory that contains the system-wide configuration
files for ATF.
.It Va atf_includedir
The path to the directory that contains the ATF header files.
.It Va atf_libdir
The path to the directory that contains the ATF libraries.
.It Va atf_libexecdir
The path to the directory that contains the auxiliary utilities of ATF,
used internally by the public tools.
.It Va atf_machine
The machine type name detected by ATF.
This should not be tunable but is provided for symmetry with
.Va atf_arch .
.It Va atf_pkgdatadir
The path to the directory that contains the files that form the ATF's
shell-scripting library.
.It Va atf_shell
The path to the shell interpreter that will be used by ATF.
.It Va atf_workdir
The path to the temporary directory that the utilities and the test
programs will use to store temporary files in.
.El
.Sh ENVIRONMENT
Every variable that is part of the static configuration can be
overridden at run-time by defining an environment variable.
This environment variable has the exact same name as the one shown by
.Nm
except that the name is all composed of uppercase letters.
.Pp
In general, empty values in the environment will be ignored unless
otherwise noted below.
.Pp
The recognized environment variables are:
.Bl -tag -width ATFXBUILDXCPPFLAGSXX
.It Ev ATF_ARCH
Overrides the built-in value of
.Va atf_arch .
.It Ev ATF_BUILD_CC
Overrides the built-in value of
.Va atf_build_cc .
.It Ev ATF_BUILD_CFLAGS
Overrides the built-in value of
.Va atf_build_cflags .
Empty values are allowed.
.It Ev ATF_BUILD_CPP
Overrides the built-in value of
.Va atf_build_cpp .
.It Ev ATF_BUILD_CPPFLAGS
Overrides the built-in value of
.Va atf_build_cppflags .
Empty values are allowed.
.It Ev ATF_BUILD_CXX
Overrides the built-in value of
.Va atf_build_cxx .
.It Ev ATF_BUILD_CXXFLAGS
Overrides the built-in value of
.Va atf_build_cxxflags .
Empty values are allowed.
.It Ev ATF_CONFDIR
Overrides the built-in value of
.Va atf_confdir .
.It Ev ATF_INCLUDEDIR
Overrides the built-in value of
.Va atf_includedir .
.It Ev ATF_LIBDIR
Overrides the built-in value of
.Va atf_libdir .
.It Ev ATF_LIBEXECDIR
Overrides the built-in value of
.Va atf_libexecdir .
.It Ev ATF_MACHINE
Overrides the built-in value of
.Va atf_machine .
.It Ev ATF_PKGDATADIR
Overrides the built-in value of
.Va atf_pkgdatadir .
.It Ev ATF_SHELL
Overrides the built-in value of
.Va atf_shell .
.It Ev ATF_WORKDIR
Overrides the built-in value of
.Va atf_workdir .
