Pull request overview
This PR migrates Lean Unicode symbol generation away from a vendored JSON file / GitHub download, and instead sources the abbreviation table from the pinned @leanprover/unicode-input npm package.
Changes:
- Remove committed/generated Lean symbol artifacts (
completions/symbols+lean.json,completions/lean-abbreviations.json) and ignore the generated output going forward. - Update
scripts/generate-symbols.mjsto read the Lean abbreviation table fromnode_modules/@leanprover/unicode-input. - Add
@leanprover/unicode-inputand wire symbol generation into the build vianpm run generate-symbolsand an updatedesbuildscript.

completions/symbols+lean.json is now generated and gitignored, but npm run typecheck (and vscode:prepublish, which runs typecheck first) does not generate it. On a fresh clone/CI this will fail because editor/src/index.ts imports ../../completions/symbols+lean.json and the file won't exist yet. Fix by running generate-symbols before typecheck (e.g., make typecheck run npm run generate-symbols && tsc -b, or add a pretypecheck script; you may also want the same for lint if eslint resolves imports).

Valid claim of the problem. I updated the typecheck script which seems to be the easiest solution. This does actually mean, that in case of the prepublish script we run it twice. But its fast and otherwise we have to change a lot more in the build process, where I think this is an okay tradeoff to make, but let me know if I should change it.

I'm totally fine with running generate-symbols twice.
It is in my opinion a bit strange to have to run it before the typechecker.
@Tammo0987 Remark: Can we add a placeholder file, maybe? That way typechecking does not fail and we still build the file in the build step.

Neat!
Added one remark under one of Copilots comments.
Can be merged after discussing my remark :)
Description
In this issue I removed the lean abbreviations file and replaced by using it directly from the lean Unicode package. I updated all necessary scripts.
Testing this PR
Test the script by following the steps in scripts/README.md for the symbol generation. Possibly just run the project as well.
Closes #324
