|
||||
This project is still under HEAVY development. While the version remains v0.1.x the API will be changing often. Once we hit v0.2.x we will start following semver.
|
||||
|
||||
Currently, the parser is able to correctly identify the start/end bounds of all the org-mode objects and elements (except table.el tables, org-mode tables are supported) but many of the interior properties are not yet populated.
|
||||
Currently, Organic parses most documents the same as the official org-mode parser. Most of the development right now is finding documents where the parsers differ and fixing those issues.
|
||||
|
||||
### Project Goals
|
||||
- We aim to provide perfect parity with the emacs org-mode parser. In that regard, any document that parses differently between Emacs and Organic is considered a bug.
|
||||
- The parser should be fast. We're not doing anything special, but since this is written in Rust and natively compiled we should be able to beat the existing parsers.
|
||||
- The parser should have minimal dependencies. This should reduce effort w.r.t.: security audits, legal compliance, portability.
|
||||
- The parser should be usable everywhere. In the interest of getting org-mode used in as many places as possible, this parser should be usable by everyone everywhere. This means:
|
||||
- It must have a permissive license for use in proprietary code bases.
|
||||
- It must have a permissive license.
|
||||
- We will investigate compiling to WASM. This is an important goal of the project and will definitely happen, but only after the parser has a more stable API.
|
||||
- We will investigate compiling to a C library for native linking to other code. This is more of a maybe-goal for the project.
