NAME

checkparser - Parse a template, outputting lots of Parse::RecDescent debugging

SYNOPSIS

  $ checkparser -h
  $ checkparser -V
  $ checkparser OPTIONS GRAMMAR
  $ checkparser OPTIONS GRAMMAR TARGETFILE

GRAMMAR

A Parse::RecDescent grammar.

TARGETFILE

A file that should be parsed by the parser generated from the specified GRAMMAR.

OPTIONS

-h, --help: Output a help message and exit.
-V, --version: Output version information and exit.
-d, --debug: Turn on debugging information for checkparser itself. May be specified more than once for (potentially) increased levels of debugging.
-w, --warn=<level>: Turn on RD_WARN warnings at the specified level (1-3), 1 being the most verbose, and 3 being the least. Defaults to '3' (only the most serious warnings).
-h, --hints: Turn on RD_HINT, which causes the parser generator to offer more detailed analyses and hints on both errors and warnings. Note that Parse::RecDescent automatically sets RD_WARN to 1 when this is turned on, regardless of the -w setting.
-p, --ptrace: Turn on tracing if the parser generator via RD_TRACE.
-t, --trace: Turn on tracing of the parser via RD_TRACE.
-r, --rule=<rulename>: Specify a rule to start the parse from. This defaults to the first rule in the grammar.
-e, --tree: Print the abstract syntax tree parsed from the specified target file using the given grammar.
