Changes since 6.3:
-Moved back to a single executable. The old intermediate format can still be
generated using the -x option. Ragel was split into frontend and backend
programs in version 5.0. This was done to encourage interoperability with
other tools. Since then, ragel has been made to work with qfsm, with ragel
producing the intermediate format and qfsm consuming it. However, there has
been no use of Ragel as a consumer of state machine data, with Ragel used as
a code generator for DFAs. This is not surprising given that much of the
complexity of Ragel is in the frontend, where the regular language to DFA
compilation happens. Since the full benefits of the split have not
materialized, and the split increases the complexity for users, Ragel has
been made once again into a single executable.
-Applied a fix to the documentation Makefile from John D. Mitchell.
-Use CXXFLAGS instead of CFLAGS for C++ compiling. Patch from Diego
'Flameeyes' Pettenò.
-Added support for DESTDIR variable. Patch from Diego 'Flameeyes' Pettenò.
-Added a script called unicode2ragel.rb for generating unicode machines to
the examples directory. From Rakan El-Khalil.
-Fixed a copy-paste error in the documentation that was reported by Jose
Quinteiro.
-Added three new write commands:
write start;
write first_final;
write error;
These generate a reference to the start, first final and error state. When
there are many different machine specifications in one file it is easy to
get the prefix for these wrong (especially when you do a lot of copy-pasting
of boilerplate). The problem can be avoided by using write commands.
-Fixed a problem reading hex numbers that have the high bit set when the
alphabet is signed and we are on 64 bit. This was reported by _why. The fix
was provided by Wialliam Morgan. The literal 0xffffffff was used for a fully
set long when -1L should be used instead.
-Fixed a bug in graphviz generation. Ragel crashed when using -V and -M and
the specified machine referenced another machine that wasn't included in the
build.
-The name "CS" is in use on OpenSolaris, changed to vCS to ease compiling
Ragel there.
-Converted to automake.
-REALLY fixed a bug that was intended to be fixed in 6.4:
Fixed a problem reading hex numbers that have the high bit set when the
alphabet is signed and we are on 64 bit. This was reported by _why. The
fix was provided by Wialliam Morgan. The literal 0xffffffff was used for
a fully set long when -1L should be used instead.
A null patch (whitespace changes) must have gotten checked after I was
testing with and without the critical one-line patch and I forgot to enable
make sure it was enabled in the final checkin version.

Too many changes and bug fixes since 5.21. See

Ragel compiles finite state machines from regular languages into
executable C, C++, Objective-C, D, Java, or Ruby code. Ragel state
machines can not only recognize byte sequences as regular expression
machines do, but can also execute code at arbitrary points in the
recognition of a regular language. Code embedding is done using
inline operators that do not disrupt the regular language syntax.
