ci: use mise for tool management

[phm07]

This PR introduces mise to manage and install tools for our dev environments and CI.
It cleans up our messy tool situation, where we previously had /tools.go, /tools/go.mod and some manually installed tools as well. It also replaces GitHub actions used for installing tools. Since the action is cached, installing Go + all needed tools only takes 3 seconds, where it before took 9 seconds just to install Go alone, which is another nice benefit.

Not sure how that is related to the changes from this PR. It does not happen on main

[apricote]

Works after yeeting mockgen from ~/go/bin/mockgen. Unfortunate that mise does not override this.

I thought mise would keep the version of the binaries locally, instead of altering my entire system.

Can we prevent mise from touching the entire system?

[apricote]

It keeps the versions "locally" and appends the path through eval $(mise activate zsh) (can be run automatically with direnv or mise hooks for zsh|bash|fish|nushell).

In cli this branch:

$ which goreleaser
/home/julian/.local/share/mise/installs/goreleaser/v2.9.0/goreleaser

I think the issue for this bug may be related to my local $PATH setup where ~/go/bin is currently before the mise paths.

[phm07]

Yes, I think there is a wrong order in PATH. Not sure if it matters that the binary is called in a //go:generate statement.

[phm07]

Adding this option to [settings] in mise.toml should fix it:
https://mise.jdx.dev/configuration/settings.html#activate_aggressive

[phm07]

@apricote Can you confirm that 30cf16269613531dc2ba47e094a99b6bbed4138d fixes the issue for your setup?

[apricote]

@phm07 and I took another look at this. Turns out it's Jetbrains Goland that adds the duplicate ~/go/bin to my $PATH at the wrong location.

I was able to get this fixed by disabling Tools > Terminal > Shell integration, which stops the Goland integrated terminal from adding more things to the PATH. mise now works great!

[jooola]

Is there a plan on how to install tool that are not supported by mise? For example installing a external-dns binary?

mise doesn't need to explicitly support tools. For each installation method there are various backends.
