Markdown YAML-Frontmatter-Support

[rimi]

Hi,

i'm currently extending TW to support YAML-Frontmattered File-Formats (i'm on node). The implementation itself is clear to me. What i'm struggling about is, how would i integrate it best into TW itself? I tried the following ways without my intented success:

• a plugin implementing a "module-type: tiddlerserializer"=> it seems to be only used when dropping a "frontmattered" MD-File into my browser and NOT when a (in my case .md-) file is loaded from the fs in node-env
• a plugin implementing "module-type: startup" => then the tiddlers are already loaded and i can parse stuff to my liking, CREATE A NEW TIDDLER but then run into trouble when writing it back to fs, because the filename is already used (but the original tiddler) and it attaches a "_$COUNTER$" suffix to the file-name

What works as expected is, when i change the file boot.js (what obviously is no good idea) by defining my own module like this:

$tw.modules.define("$:/boot/tiddlerdeserializer/md","tiddlerdeserializer",{
"text/x-markdown": function(text,fields,type) { MY CODE HERE }});

Is there a way to solve that in a more plugin'ish way?

==== SECOND TOPIC ====

The way back to the fs is implemented in sort-of more plugin'ish way, but also not really satisfactory to me and my understanding of a good integration: i use a "module-type: utils-node" and remember the current "saveTiddlerToFile" function like this:

const origSaveTiddlerToFile = $tw.utils.saveTiddlerToFile;

then i overwrite the "saveTiddlerToFile"-Function in there like so:

exports.saveTiddlerToFile = function(tiddler,fileInfo,callback) { MY NEW CODE HERE};

Within this function i simply check, if the current tiddler is something i'm interested in (basically by looking at the type "text/-x-markdown") and do my stuff by directly working with nodes fs/path-modules. Otherwise i delegate to the "rembered" function by invoking origSaveTiddlerToFile .... Kinda hack'ish isn't it?

How would i solve that in a more TW/plugin'ish way?

Thanks a lot,
Mirko

Are you creating a plugin to support metadata on top of the .md file? I would need this to open folder created by Obsidian.
