carburetta: Update to 0.8.28

0.8.28 - 2026-01-11

 - Will now emit #line so C/C++ compilation errors on generated code
   will be located at the corresponding snippet code in the .cbrt input
   file, where appropatiate. Use --nolinedir to disable.

 - Can now emit a symbol_names[] table for all ordinal constants, this
   can be useful when writing code that uses Carburetta's internal
   structures more dynamically and you wish to emit debug information.
   Only generated when --sym-names is specified.

 - Instead of specifying a filename, you can now pass - (a dash) for
   the filename and the grammar input will be read from stdin.

0.8.25 - 2025-04-14

 - New 'visit' feature. When specifying either %visit or %visit_params
   directives, Carburetta will now generate a new function
   <prefix>stack_visit() that visits all the symbol datatypes inside
   the stack, using stack internal runtime type information to dispatch
   to the appropriate snippet of code.
   Please see the https://carburetta.com/manual.html#prefixstack_visit
   section of the manual for details on the function generated.

0.8.24 - 2025-02-10

 - Fixed a bug where the generated parser would not correctly handle
   %type with no %constructor, %destructor or %move (so a plain %type
   with no initialization, destruction, nor any special data moving
   operation).
   This would cause the parser not to correctly move the data when
   resizing buffers. This did not impact %class which defines these
   operations implicitly.

 - Disabled the address sanitizer (ASAN) on MSVC for the x86 debug
   build, it trips a bug that appears to be unrelated to Carburetta
   itself. ASAN is still enabled for the x64 build.

 - Added the "kc" C99 compiler front-end and interpreter as an example.
   Currently only builds on the MSVC build for x64 because the interpeter
   uses x64 assembly to build a trampoline for function pointers, which
   is both platform and machine specific (hence MSVC x64). The build
   currently only builds a library and not yet a test program, and so is
   a work in progress.

0.8.22 - 2024-12-31

 - Removed many warnings on both gcc, clang and msvc.

 - Fixed problems with variables that were not generated in parser-only
   situations.

 - Fixed internal self-use of Carburetta, where %on_alloc_error and
   %on_internal_error assumed that user-defined parameters were available,
   this is not the case when called from cleanup.

 - Regenerate Carburetta self-use code. Resolve some issues with
   Carburetta's own use of itself (ouroboros) - you wouldn't ordinarily
   run into these because Carburetta has its own self-generated code checked
   in to prevent the bootstrap problem.

 - Carburetta internal issues due to not correctly passing the match and
   variant of tokens.

 - Many issues where %move semantics inside Carburetta did not clear
   source pointers to NULL causing destruction to be called twice. There
   is a more permanent solution for this below.

 - New %move semantics, when a %type does not have an explicit %move, then
   we no longer destruct the source data, but assume that the source is
   destructed when the copy is destructed. So, for instance, suppose we
   have %type char*, a malloc'ed string, then previously, you needed to
   add an explicit %move that cleared the source to prevent the destructor
   on the source from free'ing the pointer that was copied over.
   The new behavior is that, when relying on the default %move (a memcpy),
   the source is no longer destructed. This is very likely what users
   would expect and reduces the need for %move directives on everything.
   C++ %class types are not affected as these always generate a default
   and valid C++ style %move with appropriate destruction semantics.

 - Substantial updates to the Tilly example. Tilly is a tiling engine
   that is useful for generating machine code from expression trees.
   The Tilly example is a work in progress, it implements the algorithm
   from the 1989 paper: "Code Generation Using Tree Matching and Dynamic
   Programming" by Alfred V. Aho, Mahadevan Ganapathi and Steven W.K. Tjiang.
   The Tilly example is a good example of how to use Carburetta to implement
   a more complex multi-stage parser.
   It continues to be a work in progress and needs more documentation.

 - t16 and t17 test the new %move semantics for %type scenarios.

 - Addition of %on_scan_token and $set_token(token-id) for scanner.
   The snippet for %on_scan_token is inserted in the scan function when a new
   token is needed. The snippet can chose to do nothing (in which case the lexer
   will execute on the input and determine a new token), or it can insert a
   token in the stream using $set_token(token-id); the token-id must be a
   terminal, and no data can be set for the terminal (so the terminal should not
   have any associated type.)
   %on_next_token is now only generated for parsers.

 - Since the previous release, there is now a new example in the form of Aex-GL.
   Aex-GL is a portable OpenGL ES 2.0 software implementation in C, using Carburetta
   to parse the GLSL ES 1.0 shader language. You can find the Aex-GL example in the
   github repository at https://github.com/kingletbv/aex-gl
