Better markdown support

[gytis-ivaskevicius]

Syntax:
I have noticed that markdown files with typescript code blocks (starts with ts or typescript) don't get highlighted. Maybe the treesitter package needs to be updated?

Bat uses Sublime's .sublime-syntax highlighting definitions via the syntect library. TypeScript isn't included in the default Sublime syntax packages, which makes adding it as a Markdown code fence a bit more involved of a process.

Seems like there are 2 distinct issues here:

---

One is convincing upstream @trishume / syntect to develop/add TypeScript to its default syntax packages. I've no idea about the LOE of that.

---

Another is making "container" formats support all (or all possible?) other formats... for example:

• Markdown code blocks should/could support all formats (except maybe itself?)

  • (I've noticed other formats, like CSV, work fine directly, but not in a Markdown code block.)

• Rust (.rs) should/could support Markdown inside comments... and make code blocks there with an empty info string automatically highlight as Rust (just an example of how deep the rabbit hole could go)

• ... ?

Btw, I love bat! I use it all the time for many things. Thanks to @sharkdp and rest of the contributors for building and maintaining it!

No convincing needed, updating the sublimehq/Packages submodule will pull in TypeScript, including inside Markdown code blocks. But syntect``is a bit lacking support for newer sublime-syntax` features at the moment: trishume/syntect#570
