# The Propane Parser Generator
|
||||
|
||||
Propane is a LALR Parser Generator (LPG) which:
|
||||
Propane is an LR Parser Generator (LPG) which:
|
||||
|
||||
* accepts LR(0), SLR, and LALR grammars
|
||||
* generates a built-in lexer to tokenize input
|
||||
* supports UTF-8 lexer inputs
|
||||
* generates a table-driven shift/reduce parser to parse input in linear time
|
||||
* targets C or D language outputs
|
||||
* optionally supports automatic full AST generation
|
||||
* generates a table-driven parser to parse input in linear time
|
||||
* is MIT-licensed
|
||||
* is distributable as a standalone Ruby script
|
||||
|
||||
## Installation
|
||||
|
||||
Propane is designed to be distributed as a stand-alone single file script that
|
||||
can be copied into and versioned in a project's source tree.
|
||||
The only requirement to run Propane is that the system has a Ruby interpreter
|
||||
installed.
|
||||
The latest release can be downloaded from [https://github.com/holtrop/propane/releases](https://github.com/holtrop/propane/releases).
|
||||
|
||||
Simply copy the `propane` executable script into the desired location within
|
||||
the project to be built (typically the root of the repository) and mark it
|
||||
executable.
|
||||
TODO
|
||||
|
||||
## Usage
|
||||
|
||||
### Command Line Interface
|
||||
|
||||
Propane is typically invoked from the command-line as `./propane`.
|
||||
|
||||
Usage: ./propane [options] <input-file> <output-file>
|
||||
Options:
|
||||
-h, --help Show this usage and exit.
|
||||
--log LOG Write log file. This will show all parser states and their
|
||||
associated shifts and reduces. It can be helpful when
|
||||
debugging a grammar.
|
||||
--version Show program version and exit.
|
||||
-w Treat warnings as errors. This option will treat shift/reduce
|
||||
conflicts as fatal errors and will print them to stderr in
|
||||
addition to the log file.
|
||||
|
||||
The user must specify the path to a Propane input grammar file and a path to an
|
||||
output file.
|
||||
The generated source code will be written to the output file.
|
||||
If a log file path is specified, Propane will write a log file containing
|
||||
detailed information about the parser states and transitions.
|
||||
|
||||
### Propane Grammar File
|
||||
|
||||
A Propane grammar file provides Propane with the patterns, tokens, grammar
|
||||
rules, and user code blocks from which to build the generated lexer and parser.
|
||||
|
||||
Example grammar file:
|
||||
|
||||
```
|
||||
<<
|
||||
import std.math;
|
||||
>>
|
||||
|
||||
# Parser values are unsigned integers.
|
||||
ptype ulong;
|
||||
|
||||
# A few basic arithmetic operators.
|
||||
token plus /\+/;
|
||||
token times /\*/;
|
||||
token power /\*\*/;
|
||||
token integer /\d+/ <<
|
||||
ulong v;
|
||||
foreach (c; match)
|
||||
{
|
||||
v *= 10;
|
||||
v += (c - '0');
|
||||
}
|
||||
$$ = v;
|
||||
>>
|
||||
token lparen /\(/;
|
||||
token rparen /\)/;
|
||||
# Drop whitespace.
|
||||
drop /\s+/;
|
||||
|
||||
Start -> E1 << $$ = $1; >>
|
||||
E1 -> E2 << $$ = $1; >>
|
||||
E1 -> E1 plus E2 << $$ = $1 + $3; >>
|
||||
E2 -> E3 << $$ = $1; >>
|
||||
E2 -> E2 times E3 << $$ = $1 * $3; >>
|
||||
E3 -> E4 << $$ = $1; >>
|
||||
E3 -> E3 power E4 <<
|
||||
$$ = pow($1, $3);
|
||||
>>
|
||||
E4 -> integer << $$ = $1; >>
|
||||
E4 -> lparen E1 rparen << $$ = $2; >>
|
||||
```
|
||||
|
||||
Grammar files can contain comment lines beginning with `#` which are ignored.
|
||||
White space in the grammar file is also ignored.
|
||||
|
||||
It is convention to use the extension `.propane` for the Propane grammar file,
|
||||
however any file name is accepted by Propane.
|
||||
|
||||
See [https://holtrop.github.io/propane/index.html](https://holtrop.github.io/propane/index.html) for the full User Guide.
