tagent-cli.toml

tagent-cli keeps its settings in one TOML file, tagent-cli.toml:

• Linux: ~/.config/tagent-cli/tagent-cli.toml
• macOS: ~/Library/Application Support/tagent-cli/tagent-cli.toml
• Windows: %APPDATA%\tagent-cli\tagent-cli.toml

It is created with every setting at its default on first start, each with a comment that explains it. tagent-cli --print-default-config prints such a file without touching yours, for comparison. tagent-gui has its own settings and doesn’t read this file.

Sections

Languages

source_language and target_language are language codes (en, ru, de, …). source_language = "auto" detects the language of each text; the target can’t be auto. Names work too, in any case ("German"), and are written as codes by /save. A code Tagent doesn’t know by name (such as "uk" or "zh-TW") is passed to the provider as it is, with a warning at start. See Supported languages.

The default target is your system language, if Tagent knows it, else English.

Writing values

[interface]
copy_to_clipboard = true          # true/false and numbers without quotes
auto_hide_terminal_seconds = 0

[history]
history_file = 'C:\Users\me\history.txt'   # single quotes keep backslashes

[provider_options.work]
type = "google"
timeout_secs = "20"               # profile options are always quoted, numbers too

• A missing setting or section takes its default.
• A setting Tagent doesn’t know is reported with its line at start, with the likely intended name when it looks like a typo or sits in the wrong section. The rest of the file still applies.

Changes apply at once

tagent-cli checks the file before each translation and reloads it when it has changed, so an edit applies to the next translation. Two exceptions: the hotkeys need a restart, and a reload replaces unsaved /l and /p changes with the file’s values.

Mistakes in the file

A syntax error or a wrong value type (copy_to_clipboard = "yes") is reported with its line and column:

• at start, tagent-cli prints the message and exits;
• while it runs, it prints a warning once and keeps the previous settings until the file is fixed.

Deleting the file brings back the defaults on the next start.

How the app writes it

tagent-cli never rewrites the file on its own. It writes only when you ask:

• /save changes the languages and the three provider settings, in place, and keeps everything else, comments included;
• --update-config (or /config update) adds settings a newer version introduced; see Upgrading.

On Linux and macOS the file is written readable by you only (0600), since it can hold API keys.

Versions before 0.17.0 used tagent-cli.conf (INI). It is no longer read: copy your settings into tagent-cli.toml by hand.

The full file

What a new tagent-cli.toml contains, with English as the target language. In a real file, target_language is your system language and history_file is a full path in your data folder (see File locations).

# Text Translator Configuration File (TOML)
# This program translates selected text using keyboard shortcuts
#
# Usage:
# 1. Select text in any application
# 2. Press the translation hotkey (default: Alt+A)
# 3. Translation will be shown (enable copy_to_clipboard below to also copy it)
# 4. Type /q or /e in the interactive prompt to exit the program
#
# Configuration changes take effect immediately (no restart required),
# except where noted. Strings are quoted; true/false and numbers are not.

[provider]
# Translation service provider: a provider profile name (see "Provider profiles"
# at the end of this file); a built-in provider name works without a profile
# Supported values: google, deepl, openai
# Default: google
translate_provider = "google"

[translation]
# Languages are language codes:
# en (English), ru (Russian), es (Spanish), fr (French), de (German),
# zh (Chinese), ja (Japanese), ko (Korean), it (Italian), pt (Portuguese),
# nl (Dutch), pl (Polish), tr (Turkish), ar (Arabic), hi (Hindi)
# Other codes are passed to the provider as they are (e.g. "uk", "zh-TW").
# Names work too (e.g. "German"); /save writes them as codes.

# Source language for translation; "auto" detects it
# Default: auto
source_language = "auto"

# Target language for translation (not "auto")
# Default: the system language (from the locale), else en
target_language = "en"

[dictionary]
# Show dictionary entry for single words instead of simple translation
# Set to true to show detailed word information (definitions, part of speech, examples)
# Set to false to always use simple translation
# This feature works best with English words
show_dictionary = true

# Check spelling of single words and suggest the correct word if a typo is detected
# When enabled, misspelled words are automatically corrected and the correction is shown
# Set to false to disable spell checking (typos will fall back to simple translation)
spell_check = true

# Dictionary lookup backend (a provider profile name), independent of translate_provider
# Supported values: google, openai
# Default: google
dictionary_provider = "google"

[interface]
# Show terminal window on top when translating
# Set to true to show terminal window during translation
# Set to false to keep terminal in background
show_terminal_on_translate = true

# Auto-hide terminal after translation (in seconds)
# Set to 0 to keep terminal visible (no auto-hide)
# Set to any number > 0 to auto-hide after that many seconds
# Example: 3 = hide terminal after 3 seconds
auto_hide_terminal_seconds = 3

# Automatically copy translation result to clipboard
# Set to true to automatically copy result to clipboard after translation
# Set to false to display result only (without copying to clipboard)
# When enabled, you can paste the result anywhere with Ctrl+V
copy_to_clipboard = false

[colors]
# Supported values: Black, Red, Green, Yellow, Blue, Magenta, Cyan, White,
# BrightBlack, BrightRed, BrightGreen, BrightYellow, BrightBlue, BrightMagenta,
# BrightCyan, BrightWhite. Use "None" to disable a color.

# Whether the output is colored at all
# auto: only on a terminal that shows colors (not a pipe or a file, not TERM=dumb,
#       not an old Windows console; NO_COLOR or CLICOLOR=0 also turn colors off)
# always: always, even into a pipe or a file
# never: never, as if every color below were "None"
# Default: auto
use_colors = "auto"

# Language pair prompt (e.g., "[auto → ru]: "). Default: None (no color)
source_prompt_color = "None"

# Translation label, the provider that translated (e.g., "[google]: "). Default: BrightYellow
target_prompt_color = "BrightYellow"

# Dictionary prompt (e.g., "[Word]: "). Default: BrightYellow
dictionary_prompt_color = "BrightYellow"

# Colors used inside a dictionary article and for status messages.
# Part-of-speech labels (e.g., "Noun", "Существительное"). Default: Cyan
part_of_speech_color = "Cyan"
# Synonym brackets (e.g., "[fierce, brutal]"). Default: Green
synonym_color = "Green"
# Spelling-correction notice (e.g., "Showing translation for word violent"). Default: Magenta
notice_color = "Magenta"
# Error messages (translation, speech, clipboard, history). Default: Red
error_color = "Red"

[history]
# Save translation history to file
# Set to true to save all translations with timestamps to a text file
# Set to false to disable history logging
# History includes original text, translation, language direction, and timestamp
save_translation_history = false

# History file path
# File where translation history will be saved
# Use an absolute path: a relative one is taken from the folder tagent-cli is started in
# File will be created automatically if it doesn't exist
# On Windows, write backslashes doubled ("C:\\Users\\...") or use single quotes
history_file = "<data folder>/tagent-cli/translation_history.txt"

[hotkeys]
# Hotkey for translation
# Supported formats:
#   - Single keys: F1-F12 ONLY (other keys must use modifiers)
#   - Modifier combinations: Ctrl, Alt and/or Shift, then a letter, a digit or F1-F12:
#     Alt+Q, Ctrl+Shift+T, Alt+Shift+7, Ctrl+F9, etc.
#     NOT allowed: Shift+Key alone (interferes with text input), Win (Super),
#     Tab, Space, Enter, Esc, Backspace, Delete, Insert, arrows, Home/End/PageUp/PageDown
#     as the last key, and Ctrl+A/C/V/X/Y/Z
#   - Double-press: Ctrl+Ctrl, Shift+Shift, F8+F8 (not Alt+Alt)
# Examples:
#   translate_hotkey = "Alt+A" (default)
#   translate_hotkey = "Ctrl+Ctrl"
#   translate_hotkey = "F9"
#   translate_hotkey = "Ctrl+Shift+C"
#   translate_hotkey = "F8+F8"
# Note: Hotkey changes require application restart to take effect
translate_hotkey = "Alt+A"

[speech]
# Enable text-to-speech functionality
# Set to true to enable TTS for selected text (default)
# Set to false to disable TTS completely
enable_text_to_speech = true

# Hotkey for text-to-speech
# Supported formats (same as translate_hotkey):
#   - Single keys: F1-F12 ONLY
#   - Modifier combinations: Alt+S, Ctrl+Shift+S, etc.
#   - Double-press: Ctrl+Ctrl, Shift+Shift, F8+F8
# Examples:
#   speech_hotkey = "Alt+S"
#   speech_hotkey = "F10"
#   speech_hotkey = "Ctrl+Shift+S"
# Note: Hotkey changes require application restart to take effect
speech_hotkey = "Alt+S"

# Enable or disable the speech hotkey
# Set to true to enable the speech hotkey
# Set to false to disable speech hotkey
enable_speech_hotkey = true

# Speech synthesis backend (a provider profile name), independent of translate_provider
# Supported values: google
# Default: google
speech_provider = "google"

# Provider profiles
# One [provider_options.<name>] table per profile. translate_provider,
# dictionary_provider and speech_provider take a profile name; a built-in name
# (e.g. google) works without a table. The optional `type` key picks the provider
# kind (default: the profile name), so several configured instances of one kind can
# coexist. Keys are passed to the provider as they are (api_key, endpoint, model,
# timeout_secs, max_retries, ...), and every value is a quoted string, numbers too.
# An environment variable TAGENT_<NAME>_<KEY> (e.g. TAGENT_DEEPL_API_KEY) overrides a key.
#
# Ready-made profiles for every available provider follow, each under a ## title. To
# use one, remove the leading hash and space from each line below its title and fill in
# the empty values; the numbers shown are the defaults. Lines starting with ## are
# explanations, and a #key = "" line is an optional key: uncomment it too if you need it.
