DESCRIPTIONThis is the precompiled grammar. It is generated from
usually done by the maintainer or a developer.
Developing without precompileYou can avoid using the precompiled grammar and use the raw "grammar" file by setting this environment variable to a true value:
This is useful if you want to work on the grammar without the need to precompile everytime.
The path to the grammar file is determined using File::ShareDir in the respective "lib/auto/" subdirectory that belongs to the currently used module, depending on @INC. So when you get confused, e.g., by seemingly non-working changes, check which grammar file it is using. Some typical different @INCs are used with:
prove -l t/*.t # ./lib/ prove -b t/*.t # ./blib/ ./Build test # ./blib/ perl -MPDF::FDF::Simple ... # perl's @INC
