The upcoming OSS update will be more like a replacement of the source than an evolution of it. The directory structure has changed significantly and a lot of Java has been converted to Kotlin.
The enhanced version is now 120k lines of code so my goal is to separate the open source functionality from the proprietary code with a clean boundary to make open source releases synchronized with plugin releases like they used to be but without the need for manual merging between the two.
IntelliJ Plugin SDK development environment.
The pegdown Markdown parser used by the plugin in its original incarnation was changed to flexmark-java and pegdown dependencies have been removed as of version 2.2.0.
flexmark-java is a fork of commonmark-java, with changes:
- source element based AST with detailed break down of each element for syntax highlighting
- complete source position tracking for all elements and their lexical parts
- optimized for efficient parsing with many parser extensions installed
- unified core and extension options API to simplify parser/renderer configuration
- options to tweak core parser rules
In the process of making the needed modifications to the original commonmark-java parser, performance was impacted by about 25-35%. This still makes the new parser 7x-10x faster than intellij-markdown parser used by Markdown Support and 25x-50x faster than pegdown. As an added benefit, the new parser does not suffer from pegdown's idiosyncrasies of exponential parse times or pathological input cases that cause infinite loops in the parser's state machine.
On the coding end, the new parser is a joy to maintain and enhance. The parser architecture, inherited from commonmark-java, is easy to debug and test. Markdown element parsers have little or no interdependencies with other element parsers making it easy to fine tune parser behaviour on a per element basis and add parser configuration options to emulate other markdown processors. All this is in contrast to pegdown's one big PEG grammar implementation with everything potentially inter-dependent.
It all started with a desire to see Markdown files in PhpStorm IDE as they would look on GitHub. I was already using nicoulaj/idea-markdown plugin but found its preview was more like Craig's List than GitHub. It did not appear to have been recently updated, so I decided to fork it and modify its style sheet. How hard could that be?
I found out quickly that there was more to it than meets the eye. Rendering is done by Swing not
a browser, the parser is HTML 3.1, with many features not implemented. Additionally, the Table
extension did not work in pegdown version used by the plugin.
I upgraded the plugin to use the latest pegdown, parboiled. Fixed a few bugs. I was already
in the code so I might as well add a few more features like user editable style sheet, fix a few
more bugs, add updates to preview so that I could split the editor pane and edit in one while
seeing the preview in the other.
Now almost four years later, the plugin is brimming with features to make Markdown editing and creation a breeze. It was more work than I imagined but more satisfying that I had hoped.
It has been a fun trip down the rabbit hole of IntelliJ IDEA plugin development which started with a simple desire for a Markdown preview that looked like GitHub's.
* This plugin was originally based on the nicoulaj/idea-markdown plugin by nicoulaj, which was based on pegdown library by sirthias.
