--- @brief
---
--- https://github.com/PowerShell/PowerShellEditorServices
---
--- Language server for PowerShell.
---
--- To install, download and extract PowerShellEditorServices.zip
--- from the [releases](https://github.com/PowerShell/PowerShellEditorServices/releases).
--- To configure the language server, set the property `bundle_path` to the root
--- of the extracted PowerShellEditorServices.zip.
---
--- ```lua
--- vim.lsp.config('powershell_es', {
--- bundle_path = 'c:/w/PowerShellEditorServices',
--- })
--- ```
---
--- By default the language server is started in `pwsh` (PowerShell Core). This can be changed by specifying `shell`.
---
--- ```lua
--- vim.lsp.config('powershell_es', {
--- bundle_path = 'c:/w/PowerShellEditorServices',
--- shell = 'powershell.exe',
--- })
--- ```
---
--- Note that the execution policy needs to be set to `Unrestricted` for the languageserver run under PowerShell
---
--- By default, profile loading is disabled (`enableProfileLoading = false`) since the
--- language server runs as a background process, not an interactive session, and a
--- profile that writes to stdout can corrupt the LSP handshake. Override if needed:
---
--- ```lua
--- vim.lsp.config('powershell_es', {
--- init_options = { enableProfileLoading = true },
--- })
--- ```
---
--- If necessary, specific `cmd` can be defined instead of `bundle_path`.
--- See [PowerShellEditorServices](https://github.com/PowerShell/PowerShellEditorServices#standard-input-and-output)
--- to learn more.
---
--- ```lua
--- vim.lsp.config('powershell_es', {
--- cmd = {'pwsh', '-NoLogo', '-NoProfile', '-Command', "c:/PSES/Start-EditorServices.ps1 ..."},
--- })
--- ```
--- @return string[]? cmd
--- @return string? err
local function make_cmd()
local shell = (vim.lsp.config.powershell_es.shell or 'pwsh') --[[@as string]]
if vim.fn.executable(shell) ~= 1 then
return nil, string.format("Executable '%s' not found in system PATH.", shell)
end
local bundle_path = vim.lsp.config.powershell_es.bundle_path --[[@as string]]
if not bundle_path or bundle_path == '' then
local module = 'PowerShellEditorServices'
-- Let pwsh/powershell find the module path dynamically
local find_module_cmd = string.format('(Get-Module -ListAvailable -Name %s).ModuleBase', module)
local stdout = vim.fn.system({ shell, '-NoProfile', '-Command', find_module_cmd })
-- vim.fn.system sets v:shell_error if it fails
if vim.v.shell_error ~= 0 then
return nil, string.format('Failed to look up %s module via shell.', module)
end
bundle_path = vim.trim(stdout or ''):gsub('\\', '/')
if bundle_path == '' then
return nil,
string.format(
"PowerShell module '%s' was not found by '%s'. Please check your $env:PSModulePath.",
module,

)
end

local temp_path = vim.fn.stdpath('cache')
local command = command_fmt:format(bundle_path, bundle_path, temp_path, temp_path)
return { shell, '-NoLogo', '-NoProfile', '-Command', command }, nil
end
---@type vim.lsp.Config
return {
cmd = function(dispatchers)
local cmd, err = make_cmd()
if not cmd then
