Download terraform-ls from github assets

Language Server Version

Problem Statement

Hi,

I am the author of https://github.com/redhat-developer/lsp4ij which is a free LSP/DAP support for IntelliJ.

We provide several integration of language servers which are declared only with JSON files at https://github.com/redhat-developer/lsp4ij/tree/main/src/main/resources/templates/lsp

For instance you can see a sample with https://github.com/redhat-developer/lsp4ij/tree/main/src/main/resources/templates/lsp/rust-analyzer

I create this issue because I would like to provide an auto installer which work with any OS (I dont want to use brew for instance because it will require to install it and I am not sure that it will work with any OS).

rust-analyzer for instance provides in their releases pages all language servers for all OS at https://github.com/rust-lang/rust-analyzer/releases and LSP4IJ uses this declarative installer https://github.com/redhat-developer/lsp4ij/blob/main/src/main/resources/templates/lsp/rust-analyzer/installer.json to download the last version of rust-analyzer (by using github API) according the OS/arch of the user.

It will be fantastic if you could provide in your releases pages those download of assets to auto-install your language server without some extra configuration.

User will just open a file and LSP4IJ will provide an editor notification to install your lsp server. Here a demo with rust

Hi @angelozerr.

all language server releases are published at releases.hashicorp.com and a binary is available for most platforms. Other editors, such as Zed and Vim, also use this source to download terraform-ls.

I hope this works for you. Thanks for integrating terraform-ls!

Thanks for your answer!

The main problem with this download page is that it is impossible to know which is the last version of your language server.

User will need to select the proper version. With github releases, we can consume the github api to get the last version of assets to download. A lot of language servers provides this feature like rust, clangd, etc

For the Zed integration, I used the GitHub API to retrieve the latest release version and then downloaded the binary from releases.hashicorp.com.

However, HashiCorp also has a Releases API, which allows you to query releases by product: https://api.releases.hashicorp.com/v1/releases/terraform-ls?limit=1 This will give you the latest release and all builds.

Thanks so much @dbanck for your great info.

As your JSON file which return assets is specific, I cannot use it, so I have hard coded the ulr, but user can change it.

I have written very quickly a doc at https://github.com/redhat-developer/lsp4ij/blob/main/docs/user-defined-ls/terraform-ls.md

I have just tested with windows.

I plan to do a release today, but if you want to try ot now, you will need to install https://github.com/redhat-developer/lsp4ij?tab=readme-ov-file#testing-nightly-builds
