Adds `fnm exec` to run a shell executable with the current node version (or a custom one provided):
```
fnm exec -- node -v # will print the current Node version in fnm
fnm exec --using 12 -- node -v # will print the version of the latest node 12 installed
fnm exec --using-file -- node -v # will print the version of the current directory's node version (based on `.nvmrc` or `.node-version`)
```
* If no version is matching => we print out a message (like we used to)
* If only one version is matching (because the user provided a specific version `6.17.1` or because the prefix match only one installed version) => the version get uninstalled
* If multiple installed versions are matched: we print out the matching installed versions and ask the user to re-run the command with the correct version to uninstall.
Note: it's not possible to uninstall using `latest` or `latest-v9.x`, ... But that's already the case so nothing has changed here.
Fixes#122, and adds tests for it:
The problem, I believe, was that some files were deleted before their symlink was deleted. `Unix.stat` fails on symlinks that point to missing files. We don't really care about their stat, honestly, so we can just run `Unix.lstat` and remove them.
* Fix build with fixed versions
* Use carets
* support `lts/dubnium` format
* trim string in test
* fix typo
* Add resolution to windows.json too
* Use specific opam file
* Use variants instead of a boolean
* Add infrastructure for multishell and aliases: Aliases are required because I want to have a default node version on startup
* create alias command
* fmt
* Added aliases (Fixes#29) and opt-in multishell support (Fixes#19)
* Better docs
* update snapshot
* Some/Fail => Some/None
* add lint-staged
* use refmt and all of prettier are grouped
* System.readdir => Fs.readdir (now uses Lwt)
* use lstat for file_exists: check if symlink exists instead of actual linked file. also, initialize the Random seed on Env
* Remove fish set options that were added in trial and error
* Bootstrap script
* add bootstrap documentation
