Completions

Completions come from the language server for the file you are editing, and optionally from words already in the buffer. Tyrn also offers model-powered inline suggestions, which are covered in Autocomplete.

Use completions

The menu opens as you type. To open it yourself, press ctrl-space. ctrl-shift-space opens a menu of words from the buffer only.

Task Keybinding
Open completions ctrl-space
Open word completions ctrl-shift-space
Next, previous item down or ctrl-n, up or ctrl-p
Accept enter or tab
Accept and replace the text after the cursor shift-enter

Turn completions off or tune them

settings.json
{
  // Stop the menu from opening while you type. You can still open it with ctrl-space.
  "show_completions_on_input": false,
  "completions": {
    // "enabled", "fallback" (default) or "disabled"
    "words": "fallback",
    "words_min_length": 3,
    // Set to false to use only word completions.
    "lsp": true,
    // Milliseconds to wait for a language server. 0 waits indefinitely.
    "lsp_fetch_timeout_ms": 0,
    // "insert", "replace", "replace_subsequence" or "replace_suffix" (default)
    "lsp_insert_mode": "replace_suffix"
  }
}

completions.words controls whether words from the document join the list. "fallback" uses them only when the language server errors or times out. Markdown and plain text turn word completions off by default.

Setting Default What it does
show_completion_documentation true Shows documentation beside items
completion_menu_item_kind "off" "symbol" adds a one-letter badge for the item kind
completion_detail_alignment "left" Aligns detail text left or right
snippet_sort_order "inline" Where snippets sort: "top", "inline", "bottom" or "none"
auto_signature_help false Shows the method signature while you type arguments

Snippets appear in the menu too. See Snippets.

Language servers

Which language server provides completions is a per-language choice. Most common languages work without setup. See Languages and Configuring languages.
