Using tenv as a Go module?

[corrieriluca]

Hi all,

I was wondering if tenv was suitable to be used as a Go module inside a Go codebase. We would like to use it as a replacement of Hashicorp's hc-install module which only supports Terraform.

From what I understand, reading documentation and code, tenv does not have a stable and usable Go API yet. Could anyone confirm this?

Given the current state, would you recommend to use tenv as a CLI tool that we would call from our Go code?

Thank you in advance for your help!

Best regards,
Luca

Hi @corrieriluca,

The Go API did not change often (although sometimes new feature or fix need it), however we haven't set compatibility goal on it.

Usage could look like :

conf, err := config.InitConfigFromEnv()
conf.InitDisplayer(false)
hclParser := hclparse.NewParser()
versionManager := builder.Builders[toolName](conf, hclParser)

err = versionManager.Install("latest") // can use semantic.LatestKey constant, other supported value : version, version contraints, known behavior

for more on VersionManager available method (see go doc).

Thank you for your response, I managed to use it properly 👍

@corrieriluca I think that you can use it as go library. We change the major version in case of changing anything major in the behavior.

Hi @corrieriluca, @kvendingoldo,

I started to work on tenvlib, any remark about the API ?

[kvendingoldo]

Wow! Great. I will respond to this discussion if I have any ideas.

[corrieriluca]

That's great! That could fit my use case, I implemented much the same thing on my side, it's better to be integrated into tenv directly 👍

Just one question: what is the equivalent of tenv <tool> detect? The Evaluate function?

[dvaumoron]

I didn't report the equivalent of Detect yet 😅

I think the ReadDefaultConstraint, SetConstraint and ResetConstraint will be useful too
