1 Introduction

Paul's Parser for Tom's Own Minimal Language

Common Lisp TOML parser.

Compliance notes

• Supports the TOML v0.1.0 spec with the following exceptions:

• Complications arising from escaping quote & comment syntax are known and deferred until someone gets bit and is angry enough to send a pull request fixing them.

• Not enforcing array homogeneity. Partly this is because of Postel's dictum, but partly because it might be more convenient to have heterogenous lists. Future work - might add a strict mode which throws errors here.

• Unicode support may have some issues. It should work, but Unicode on Common Lisp is sometimes dependant on your system's configuration. Testing should be done before rolling your work to production.

• Common Lisp is pretty good with numbers. Therefore, instead of manually differentiating between floats and integers, pp-toml calls them NUMBERS and lets your Lisp take care of the rest. Again, test before rolling to production.

Testing

To run the tests, do this:

 sbcl --script run-sbcl-tests.lisp

Which will produce a test report.

Contributions

Gratefully accepted. Please add test cases for bug reports you fix or features you add.

Remarks

Since Tom thought it'd be a good idea to put his name on the language, I'm putting my name on this parser.

5.1 Exported definitions

5.1.1 Functions

Function: parse-string STRING

Returns the toml parsed structure from ‘string‘ or :parse-error

Package

pp-toml

Source

pp-toml.lisp (file)

Function: parse-toml STRING &key STRICT

Parse a TOML ‘string‘, returning a hash table comparable by EQUAL.

‘strict‘ is not supported at present.

Package

pp-toml

pp-toml.lisp (file)

Function: strip-comments STRING

Strips the comments from the string

Package

Special Variable: *comment-scanner*

Scanner for # comments. Handles "#" strings

Package

Function: not-special-case CHAR

Package

pp-toml.lisp (file)

Function: process-value-data VALUE

‘value‘ may be any of the standard toml value types: array,
datetime, bool, number, or string. Of those, arrays are a special case:
Supposing an array is encountered, process-value-data recurses upon the array.

Toml does not support references as of v0.1, and there for we can traverse arrays without cyles of references.
