feat(saheli): add jetbrains-plugins module for issue #208 …

[Sahelisaha04]

Description

Enhanced the JetBrains module to support pre-installing plugins in workspaces. When users specify plugin IDs, the module creates configuration files that automatically suggest plugin installation when connecting via JetBrains Gateway. This eliminates the need for manual plugin installation after workspace setup.

Type of Change

• New module
• Bug fix
• Feature/enhancement
• Documentation
• Other

Module Information

• Path: registry/coder/modules/jetbrains
• New version: v1.0.1
• Breaking change: [ ] Yes [x] No

Changes Made

1. Added Plugin Configuration Variable

$ grep -A 4 "variable \"plugins\"" main.tf
variable "plugins" {
  type        = list(string)
  description = "A list of plugin IDs to pre-install in the JetBrains IDEs. Plugin IDs can be found on the JetBrains Marketplace."
  default     = []
}

2. Created Plugin Configuration Script

$ ls -la scripts/
total 12
drwxrwxr-x 2 user user 4096 Jan 12 10:30 .
drwxrwxr-x 3 user user 4096 Jan 12 10:29 ..
-rw-rw-r-- 1 user user 4985 Jan 12 10:30 install-plugins.sh

3. Added Conditional Script Resource

$ grep -A 8 "coder_script.*jetbrains_plugins" main.tf
resource "coder_script" "jetbrains_plugins" {
  count              = length(var.plugins) > 0 ? 1 : 0
  agent_id           = var.agent_id
  display_name       = "Configure JetBrains Plugins"
  icon               = "/icon/jetbrains-toolbox.svg"
  run_on_start       = true
  start_blocks_login = false
  timeout            = 120
}

Testing & Validation

Terraform Validation

$ terraform init
Initializing the backend...
Initializing provider plugins...
- Installing coder/coder v2.8.0...
- Installing hashicorp/http v3.5.0...
Terraform has been successfully initialized!

$ terraform validate
Success! The configuration is valid.

Test Plan with Plugins

$ terraform plan -var='agent_id=demo-agent' -var='folder=/workspace' -var='default=["IU","PY"]' -var='plugins=["org.jetbrains.plugins.github","com.intellij.ml.llm"]'

Terraform will perform the following actions:

  # coder_app.jetbrains["IU"] will be created
  + resource "coder_app" "jetbrains" {
      + display_name = "IntelliJ IDEA"
      + slug         = "jetbrains-iu"
      + url          = "jetbrains://gateway/coder?&workspace=default&owner=default&folder=/workspace&url=https://mydeployment.coder.com&token=$SESSION_TOKEN&ide_product_code=IU&ide_build_number=251.26927.53"
    }

  # coder_app.jetbrains["PY"] will be created
  + resource "coder_app" "jetbrains" {
      + display_name = "PyCharm"
      + slug         = "jetbrains-py"
    }

  # coder_script.jetbrains_plugins[0] will be created
  + resource "coder_script" "jetbrains_plugins" {
      + display_name = "Configure JetBrains Plugins"
      + run_on_start = true
      + script       = <<-EOT
            PLUGINS=(org.jetbrains.plugins.github com.intellij.ml.llm)
            SELECTED_IDES=(IU PY)
            echo "🚀 JetBrains Plugin Configuration Setup"
            echo "Configuring 2 plugin(s) for auto-installation..."
        EOT
    }

Plan: 3 to add, 0 to change, 0 to destroy.

Script Syntax Check

$ bash -n scripts/install-plugins.sh
# No output = syntax is valid

Format Check

$ terraform fmt -check
# No output = formatting is correct
