--- Language server for Apex.
---
--- For manual installation, download the JAR file from the [VSCode
--- extension](https://github.com/forcedotcom/salesforcedx-vscode/tree/develop/packages/salesforcedx-vscode-apex) and adjust the `apex_jar_path` appropriately.
---
--- ```lua
--- vim.lsp.config('apex_ls', {
---   apex_jar_path = '/path/to/apex-jorje-lsp.jar',
---   apex_enable_semantic_errors = false, -- Whether to allow Apex Language Server to surface semantic errors
---   apex_enable_completion_statistics = false, -- Whether to allow Apex Language Server to collect telemetry on code completion usage
--- }
---```
---
--- Example configuration using Mason:
---
---```lua
--- vim.lsp.config('apex_ls', {
---   apex_jar_path = vim.fn.stdpath('data') .. '/mason/share/apex-language-server/apex-jorje-lsp.jar',
--- }
---```
---
--- For a complete experience, you may need to ensure the treesitter parsers for 'apex' are installed (:TSInstall apex) as well as configure the filetype for apex (*.cls) files:
---
--- ```lua
--- vim.filetype.add({
---   pattern = {
---     ['.*/*.cls'] = 'apex',
---   },
--- })
--- ```

---@type vim.lsp.Config
return {
  cmd = function(dispatchers, config)
    local local_cmd = {
      vim.env.JAVA_HOME and (vim.env.JAVA_HOME .. '/bin/java') or 'java',
      '-cp',
      config.apex_jar_path,
      '-Ddebug.internal.errors=true',
      '-Ddebug.semantic.errors=' .. tostring(config.apex_enable_semantic_errors or false),
      '-Ddebug.completion.statistics=' .. tostring(config.apex_enable_completion_statistics or false),
      '-Dlwc.typegeneration.disabled=true',
    }
    if config.apex_jvm_max_heap then
      table.insert(local_cmd, '-Xmx' .. config.apex_jvm_max_heap)
    end
    table.insert(local_cmd, 'apex.jorje.lsp.ApexLanguageServerLauncher')

    return vim.lsp.rpc.start(local_cmd, dispatchers)
  end,
  filetypes = { 'apex', 'apexcode' },
  root_markers = {
    'sfdx-project.json',
  },
