Include hls ./install script when loading haskell-language-server with itself

[jneira]

• From Failing to use haskell-language-server on itself #121
• The install script lives under the subdirectory install and it does not belong to the main project (it is not a component or a subppackage of hls)
  • This was on purpose, to isolate it and use its own dependencies, resolver, etc
• So if you load haskell-language-server on itself it is not able to load the install script, even if you add it in the hie.yaml
• The workaround is open directly the install subdir in other editor window
• @sir4ur0n suggested that it would be better to make possible open all the haskell code in the same editor "session"
  • though a change in hie-bios to make it able to load different stack (and cabal) projects with the same config

Thank you for creating this dedicated issue for the ./install folder!

though a change in hie-bios to make it able to load different stack (and cabal) projects with the same config

I'm sorry, I'm not sure I understand what you mean. Is it already supported by hie-bios? Or is it a prerequisite?
If so, is there already such an issue in hie-bios repo?

It is not supported by hie-bios and it would be a prerequisite for use hls main project and install within an unique hie.yaml. I am afraid there is no issue about.

Thank you!

In #147 I have marked the ./install/ directory with a none cradle, so that whoever opens the full hls project in any editor will not get any error. This is the best I could think of until hie-bios supports multi-stack project.

[sir4ur0n]

I just opened haskell/hie-bios#191 to track this feature.

As @mipckering suggested we could use a ./install/hie.yaml to load them and add a specific ./install/hie.yaml.cbl and ./install/hie.yaml.stack in the repo if it works

[sir4ur0n]

Yes that was my intention too, I'll try Matt's solution tonight and if it works, I will adapt my PR accordingly
