Support HCL2 and Terraform 0.12

[mkuzmin]

A preview of Terraform 0.12 and HCL2 with a bunch of new features and breaking compatibility changes have been announced.
They are planning to release it later this summer.

Our plugin needs to support it at some point.

seems like it's time to get started ;-)

We use this plugin on a daily basis.
would be awesome if it will support the new HCL2 format!

+1, I don't like "First-Class Expressions" being marked as mistake

[tskotov]

+1 for HCL2/TF0.12 support!

[VladRassokhin]

"First-Class Expressions" being marked as mistake

@cehrig what do you mean?

Even if Terraform provides a migration tool, I'm sure we have plenty of places for useful inspections

[d-helios]

Terraform 0.12-beta1 now available! It will be nice to see HCL2 support in favourite IDE ))

[StephenKing]

@VladRassokhin we're heavy users of this great plugin and looking forward to Terraform 0.12.

Is there any way how we can help to sponsor development?

[suslovsergey]

if i can donate for resolving this issue - i will donate!

[VladRassokhin]

HCL2 (Terraform 0.12+) support will be part of IntelliJ-Terraform plugin for IntelliJ 2019.2 as plugin will become part of IntelliJ.

You can kinda-sponsor development - buy any JetBrains product.

[brikis98]

Looking forward to seeing this!

Is 0.12 support part of the 2019.2 EAP?

[Tom-Mann]

Don't see this in the 2019.2 intellij/pycharm releases ?

[bohdanyurov-gl]

TF 0.12 has been released: https://www.hashicorp.com/blog/announcing-terraform-0-12

[bohdanyurov-gl]

@VladRassokhin is there any estimated release date or an issue tracker?

[Acen]

@VladRassokhin is there any estimated release date or an issue tracker?

There aren't any references within their tracker. https://youtrack.jetbrains.com/issues

Edit: It hasn't been added as part of the 2019.1.3 RC either.

It appears there is an hcl2 branch for this plugin so @VladRassokhin has/had started working on it: https://github.com/VladRassokhin/intellij-hcl/tree/hcl2 but it was last updated in Aug, 2018 so not sure what state it's in.

[VladRassokhin]

As I've stated a bit early

HCL2 (Terraform 0.12+) support will be part of IntelliJ-Terraform plugin for IntelliJ 2019.2

Unfortunately not yet in 2019.2 EAP 1, though I'll investigate whether it's possible to publish plugin on plugins.jetbrains.com (build compatible with 2019.2 EAP or 2019.1.2)

All necessary code for HCL2 is already there, however it's not open-source

[ajorpheus]

though I'll investigate whether it's possible to publish plugin on plugins.jetbrains.com (build compatible with 2019.2 EAP or 2019.1.2)

This will be awesome.

Unfortunately (or fortunately), I've found the Terraform integration in Intellij to be much better than VS Code and that's pretty much due to how well this plugin works.

[bowczarek]

As some guys told that already above, TF/HCL support in IJ is awesome, thanks a lot for your great work!
Me and my teammates are also waiting for TF0.12/HCL 2.0 support since we already migrated our code base because of so many great features and finally expressions treated as first class citizens.

Having that said @VladRassokhin do you have any sort of ETA when a new plugin may come up, either for 2019.1.2 or 2019.2 EAP as you mentioned already, apart from final 2019.2 release that is scheduled for July :( ?

[OGProgrammer]

[VladRassokhin]

I've uploaded version 0.7.0 to plugins repository.
It's compatible with IntelliJ platform 2019.1+, please try it out.

Possible caveats: new templates syntax (%{}).
Please report bugs if any.

[bohdanyurov-gl]

@VladRassokhin looks like TF 0.12 is supported only partially, code navigation or inspections do not work.

Anyway, thank you for uploading it, at least it does not try to mark every template as broken now :)

[VladRassokhin]

@bohdanyurov-gl Examples maybe? It's hard to see what you mean since I'm not developing Terraform configs daily.

[benosman]

@VladRassokhin

Thanks for your work on this plugin!

A couple of things I noticed that have some issues:

• Variables can now have more types, such as bool, number and also more complex type constructors:
  Docs -> https://www.terraform.io/docs/configuration/variables.html#type-constraints

• Complex lookups inside templates show as unresolved references. The new template system allows for some very dynamic code which is likely impossible for the plugin to determine, very often though they are highlighted red due to being unresolved.

[bohdanyurov-gl]

@VladRassokhin
Even trivial constructions don't work:

IDEA does not see "locals.foo" as a reference to the local variable.

Example for tf 0.11 syntax:

I'm using latest IDEA (2019.1.3 Ultimate) and TF (v0.7.2) plugin

[bohdanyurov-gl]

Update: sorry for confusion. Looks like I was using v0.7.1, latest one works

[VladRassokhin]

Please open new issues if problems arises
