- This is built into Cobra the argument parser. Now `ghcs --version`
exists.
- When we prepare to bump the version, we need to remember to update
this value else the Homebrew formula, GitHub releases and the `ghcs
--version` output will be mismatched.
- Fixes https://github.com/github/ghcs/issues/16.
- I have my GitHub API token in my environment as
`HOMEBREW_GITHUB_API_TOKEN`, so with things that need `GITHUB_TOKEN` I
have to remember to `export GITHUB_TOKEN=$HOMEBREW_GITHUB_API_TOKEN`.
- I didn't for this tool, and got this unfriendly error message:
```
❯ ghcs list
Error: error getting user: Bad credentials
Usage:
ghcs list [flags]
Flags:
-h, --help help for list
error getting user: Bad credentials
```
- This moves the "do you have a `GITHUB_TOKEN`" question to the very
beginning (no guarantees about org SSO access, just a string that
exists), erroring out with a nice message if users don't have that
envvar set:
```
issyl0 in cetus in ~/repos/github/ghcs/cmd/ghcs on gracefully-fail-if-token-envvar-unset
❯ ./ghcs list
The GITHUB_TOKEN environment variable is required. Create a Personal Access Token with org SSO access at https://github.com/settings/tokens/new.
