# trparse
## Summary
Parse a grammar or use generated parse to parse input
## Description
Parse files and output to stdout parse tree data.
The tool requires a pre-built parser via trgen for a grammar
for anything other than the standard parser grammars that
are supported. To specify the grammar, you can either
be in a trgen-generated parser directory, or use the -p option.
If using positional args on the command line, a file is parse
depending on the extension of the file name:
* `.g2` for an Antlr2
* `.g3` for an Antlr3
* `.g4` for an Antlr4
* `.y` for a Bison
* `.ebnf` for ISO EBNF
You can force the type of parse with
the `--type` command-line option:
* `antlr2` for Antlr2
* `antlr3` for Antlr3
* `antlr4` for Antlr4
* `bison` for Bison
* `ebnf` for ISO EBNF
* `gen` for the `Generated/` parser
## Usage
trparse (<string> | <options>)*
-i, --input      Parse the given string as input.
-t, --type       Specifies type of parse, antlr4, antlr3, antlr2, bison, ebnf, gen
-s, --start-rule Start rule name.
-p, --parser     Location of pre-built parser (aka the trgen Generated/ directory)
## Examples
trparse Java.g2
trparse -i "1+2+3"
trparse Foobar.g -t antlr2
echo "1+2+3" | trparse | trtree
mkdir out; trparse MyParser.g4 MyLexer.g4 | trkleene | trsponge -o out
