Sounds good. What's your use-case?

[sdavids]

The main advantage is not having a required .lycheecache entry in your .gitignore.

---

• global cache directory ($XDG_CACHE_HOME/lychee/cache, $HOME/Library/Caches/lychee, %LOCALAPPDATA%\lychee\Cache …)—depending on your OS, files in those directories are not backed up or indexed, cleaned on system reboot, and/or placed on an in-memory mount.

• a directory already in your .gitignore, i.e., node_modules/.cache/lychee/cache

In the latter case, you could also keep your tools' caches all in one place:

eslint --cache --cache-location ./node_modules/.cache/eslint/.eslintcache

{
  "$schema": "https://json.schemastore.org/tsconfig",
  "compilerOptions": {
    "tsBuildInfoFile": "./node_modules/.cache/tsc/tsconfig.tsbuildcache"
  }
}

https://prettier.io/docs/cli#--cache-location ⇒ ./node_modules/.cache/prettier/.prettier-cache

I see. So it's mostly a quality-of-life improvement, not a blocker, right?

I like the idea and the new parameter name. We'd accept a pull request for that in case someone wants to give it a shot.
