classrebuildParsers.php
: Preprocesses the grammar and builds the parser using kmyacc
The .y
file is a normal grammer in kmyacc
(yacc
) style, with some transformations
applied to it:
Name[..., ...]
. This is transformed into
new Name(..., ..., attributes())
rebuildParsers.php
for a list)In order to rebuild the parser, you need moriyoshi's fork of kmyacc.
After you compiled/installed it, run the rebuildParsers.php
script.
By default only the Parser.php
is built. If you want to additionally emit debug symbols and create y.output
, run the
script with --debug
. If you want to retain the preprocessed grammar pass --keep-tmp-grammar
.
