We did not check which packages are needed to build on other distros or OS. We are waiting for your contribution ;)

Configuration

If $XDG_CONFIG_HOME/tym/config.lua exists, it is executed when the app starts. You can change the path with the --use/-u option.

-- At first, you need to require tym module
local tym = require('tym')

-- set individually
tym.set('width', 100)

tym.set('font', 'DejaVu Sans Mono 11')

-- set by table
tym.set_config({
  shell = '/usr/bin/fish',
  cursor_shape = 'underline',
  autohide = true,
  color_foreground = 'red',
})

See wiki to check out the advanced examples.

All available config values are shown below.

field name	type	default value	description
`shell`	string	`$SHELL` → `vte_get_user_shell()` → `'/bin/sh'`	Shell to execute.
`term`	string	`'xterm-256color'`	Value of `$TERM`.
`title`	string	`'tym'`	Initial window title.
`font`	string	`''`	You can specify font with `'FAMILY-LIST [SIZE]'`, for example `'Ubuntu Mono 12'`. The value is parsed by `pango_font_description_from_string()`. If empty string is set, the system default fixed width font will be used.
`icon`	string	`'utilities-terminal'`	Name of icon. cf. Icon Naming Specification
`role`	string	`''`	Unique identifier for the window. If empty string is set, no value set. (cf. gtk_window_set_role())

`cursor_blink_mode`	string	`'system'`	`'system'`, `'on'` or `'off'` can be used.
`cjk_width`	string	`'narrow'`	`'narrow'` or `'wide'` can be used.
`background_image`	string	`''`	Path to background image file.
`uri_schemes`	string	`'http https file mailto'`	Space-separated list of URI schemes to be highlighted and clickable. Specify empty string to disable highlighting. Specify `'*'` to accept any strings valid as schemes (according to RFC 3986).
`width`	integer	`80`	Initial columns.
`height`	integer	`22`	Initial rows.

`ignore_default_keymap`	boolean	`false`	Whether to use default keymap.
`autohide`	boolean	`false`	Whether to hide mouse cursor when the user presses a key.
`silent`	boolean	`false`	Whether to beep when bell sequence is sent.
`bold_is_bright`	boolean	`false`	Whether to make bold texts bright.
`color_window_background`	string	`''`	Color of the terminal window. It is seen when `'padding_horizontal'` `'padding_vertical'` is not `0`. If you set `'NONE'`, the window background will not be drawn.
`color_foreground`, `color_background`, `color_cursor`, `color_cursor_foreground`, `color_highlight`, `color_highlight_foreground`, `color_bold`, `color_0` ... `color_15`	string	See the next section	You can specify standard color string such as `'#f00'`, `'#ff0000'`, `'rgba(22, 24, 33, 0.7)'` or `'red'`. It will be parsed by `gdk_rgba_parse()`. If empty string is set, the VTE default color will be used. If you set `'NONE'` for `color_background`, the terminal background will not be drawn.

Theme customization

When $XDG_CONFIG_HOME/tym/theme.lua exists, it is loaded before loading config. You can change the path by using the --theme/-t option. The following is an example, whose color values are built-in default. They were ported from iceberg.

local bg = '#161821'
local fg = '#c6c8d1'
return {
  color_background = bg,
  color_foreground = fg,
  color_bold = fg,
  color_cursor = fg,
  color_cursor_foreground = bg,
  color_highlight = fg,
  color_highlight_foreground = bg,
  color_0  = bg,
  color_1  = '#e27878',
  color_2  = '#b4be82',
  color_3  = '#e2a478',
  color_4  = '#84a0c6',
  color_5  = '#a093c7',
  color_6  = '#89b8c2',
  color_7  = fg,
  color_8  = '#6b7089',
  color_9  = '#e98989',
  color_10 = '#c0ca8e',
  color_11 = '#e9b189',
  color_12 = '#91acd1',
  color_13 = '#ada0d3',
  color_14 = '#95c4ce',
  color_15 = '#d2d4de',
}

You need to return the color map as table.

Keymap

Default keymap

Key	Action
Ctrl Shift c	Copy selection to clipboard.
Ctrl Shift v	Paste from clipboard.
Ctrl Shift r	Reload config file.

Customizing keymap

You can register keymap(s) using tym.set_keymap(accelerator, func) or tym.set_keymaps(table). accelerator must be in a format parsable by gtk_accelerator_parse(). If a truthy value is returned, the event propagation will not be stopped.

-- also can set keymap
tym.set_keymap('<Ctrl><Shift>o', function()
  local h = tym.get('height')
  tym.set('height', h + 1)
  tym.notify('Set window height :' .. h)
end)

-- set by table
tym.set_keymaps({
  ['<Ctrl><Shift>t'] = function()
    tym.reload()
    tym.notify('reload config')
  end,
  ['<Ctrl><Shift>v'] = function()
    -- reload and notify
    tym.send_key('<Ctrl><Shift>t')
  end,

  ['<Shift>y'] = function()
    tym.notify('Y has been pressed')
    return true -- notification is shown and `Y` will be inserted
  end,
  ['<Shift>w'] = function()
    tym.notify('W has been pressed')
    -- notification is shown but `W` is not inserted
  end,
})

If truthy value is returned in a callback function, the default action will be stopped.

tym.set_hooks({
  title = function(t)
    tym.set('title', 'tym - ' .. t)
    return true -- this is needed to cancenl default title application
  end,
})

--- NOTE:
-- If you set the hook to 'clicked' handler, you need to open URI manually like below,
tym.set_hook('clicked', function(button, uri)
  print('you pressed button:', button) -- 1:left, 2:middle, 3:right

  -- open URI only by middle click
  if button == 2 then
    if uri then
      print('you clicked URI: ', uri)
      tym.open(uri)
      -- disable the default action 'put clipboard' when open URI
      return true
    end
  end
end)

Interprocess communication using D-Bus

Each tym window has an unique ID, which can be checked by tym.get_id() or $TYM_ID, and also listen to D-Bus signal/method call on the path /me/endaaman/tym<ID> and the interface name me.endaaman.tym.

Signals

Name	Input(D-Bus signature)	Description
`hook`	`s`	Triggers `signal` hook.

For example, when you prepare the following config and command,

local tym = require('tym')
tym.set_hook('signal', function (p)
  print('Hello from DBus signal')
  print('param:', p)
end)

$ dbus-send /me/endaaman/tym0 me.endaaman.tym.hook string:'THIS IS PARAM'

or

tym.signal(0, 'hook', {'THIS IS PARAM'}) -- NOTICE: param must be table

you will get an output like below.

Hello from DBus signal
param:  THIS IS PARAM

Alternatively, you can use tym command to send signal.

$ tym --signal hook --dest 0 --param 'THIS IS PARAM'

If the target window is its own one, it will the value of $TYM_ID and --dest can be omitted. So it is enough like below.

$ tym --signal hook --param 'THIS IS PARAM'

Methods

Name	Input (D-Bus signature)	Output (D-Bus signature)	Description
`get_ids`	None	`ai`	Get all tym instance IDs.
`echo`	`s`	`s`	Echo output the same as input.
`eval`	`s`	`s`	Evaluate one line lua script. `return` is needed.
`eval_file`	`s`	`s`	Evaluate a script file. `return` is needed.
`exec`	`s`	None	Execute one line lua script without outputs.
`eval_file`	`s`	None	Execute a script filt without outputs.

For example, when you exec the command,

$ dbus-send --print-reply --type=method_call --dest=me.endaaman.tym /me/endaaman/tym0 me.endaaman.tym.eval string:'return "title is " .. tym.get("title")'

then you will get like below.

method return time=1646287109.007168 sender=:1.3633 -> destination=:1.3648 serial=39 reply_serial=2
   string "title is tym"

As same as signals, you can use tym command to execute method calling.

$ tym --call eval --dest 0 --param 'return "title is " .. tym.get("title")'

Of course, --dest can be omitted as well.

Options

`--help` `-h`

$ tym -h

`--use=<path>` `-u <path>`

$ tym --use=/path/to/config.lua

If NONE is provided, all config will be default (user-defined config file will not be loaded).

$ tym -u NONE

`--theme=<path>` `-t <path>`

$ tym --use=/path/to/theme.lua

If NONE is provided, default theme will be used.

$ tym -t NONE

`--signal=<signal name>` `-s <signal name>`

$ tym --signal hook

Sends a D-Bus signal to the current instance (determined by $TYM_ID environment value). To send to another instance, use --dest (or -d) option.

`--call=<method name>` `-c <method name>`

Calls D-Bus method of the current instance (determined by $TYM_ID environment value). To call it of another instance, provide --dest (or -d) option.

$ tym --call eval --param 'return 1 + 2'

`--daemon`

This makes tym a daemon process, which has no window or application context.

$ tym --daemon

To enable the daemon feature, set tym-daemon.desktop as auto-started on the DE's settings or add the line tym --daemon & in your .xinitrc.

`--cwd=<path>`

This sets the terminal's working directory. <path> must be an absolute path. If unspecified tym will use the current working directory of the terminal invocation.

$ tym --cwd=/home/user/projects

`--<config option>`

You can set config value via command line option.

$ tym --shell=/bin/zsh --color_background=red --width=40 --ignore_default_keymap

`--isolated`

$ tym --isolated

This option enables tym to create a separate process for each instance. Then an app instance will be isolated from D-Bus and no longer have ability to handle D-Bus signals/method calls.

`--` ("double dash" option)

tym also accepts double dash -- option as the command line to spawn.

$ tym -- less -N Dockerfile
