# PDF::FDF::Simple::Grammar(3pm)

Precompiled grammar for PDF::FDF::Simple

## NAME

PDF::FDF::Simple::Grammar - Precompiled grammar for PDF::FDF::Simple

## DESCRIPTION

This is the precompiled grammar. It is generated from

```
  lib/auto/PDF/FDF/Simple/grammar
```

using

```
  ./Build grammar
```

usually done by the maintainer or a developer.

## Developing without precompile

You can avoid using the precompiled grammar and use the raw `"grammar"` file by setting this environment variable to a true value:

```
  export PDF_FDF_SIMPLE_IGNORE_PRECOMPILED_GRAMMAR=1
```

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 `@INC`s are used with:

```
  prove -l t/*.t               # ./lib/
  prove -b t/*.t               # ./blib/
  ./Build test                 # ./blib/
  perl -MPDF::FDF::Simple ...  # perl's @INC
```
