TUI (Terminal User Interface)

TUI Allows you to:

  • Review processes status
  • Start processes (only completed or disabled)
  • Stop processes
  • Review logs
  • Restart running processes

TUI is the default run mode, but it's possible to disable it:

./process-compose -t=false

Control the UI log buffer size:

log_level: info
log_length: 1200 #default: 1000
processes:
  process2:
    command: "ls -R /"

💡 Using a too large buffer will put more penalty on your CPU.

By default process-compose uses the standard ANSI colors mode to display logs. However, you can disable it for each process:

processes:
  process_name:
    command: "ls -R /"
    disable_ansi_colors: true #default false

💡 Too long log lines (above 2^16 bytes long) can cause the log collector to hang.

Shortcuts Configuration

Default shortcuts can be changed by placing shortcuts.yaml in your $XDG_CONFIG_HOME/process-compose/ directory.
The default process-compose configuration is defined as:

# $XDG_CONFIG_HOME/process-compose/shortcuts.yaml
shortcuts:
  log_follow: # action name - don't edit
    toggle_description: # optional description for toggle buttons. Will use default if not defined
      false: Follow Off
      true: Follow On
    shortcut: F5 # shortcut to be used
  log_screen:
    toggle_description:
      false: Half Screen
      true: Full Screen
    shortcut: F4
  log_wrap:
    toggle_description:
      false: Wrap Off
      true: Wrap On
    shortcut: F6
  process_restart:
    description: Restart # optional description for a button. Will use default if not defined
    shortcut: Ctrl-R
  process_screen:
    toggle_description:
      false: Half Screen
      true: Full Screen
    shortcut: F8
  process_start:
    description: Start
    shortcut: F7
  process_stop:
    description: Stop
    shortcut: F9
  quit:
    description: Quit
    shortcut: F10

shortcuts.yaml can contain only the values you wish to change, default values will be used for the rest.
For example if you want to replace the default quit shortcut to be F3 instead of F10 and rename the process_stop to be Terminate, the configurion will be as follows: 

# $XDG_CONFIG_HOME/process-compose/shortcuts.yaml
shortcuts:
  process_stop:
    description: Terminate
  quit:
    shortcut: F3

TUI Themes

The default shortcut for theme selection is CTRL-T. Process Compose comes with 4 pre-loaded themes. These can be extended in 2 ways:

  1. By contributing a new theme, by creating a PR with a new theme in the src/config/themes directory.
  2. Adding your own theme by placing theme.yaml in your $XDG_CONFIG_HOME/process-compose/ directory.

The default process-compose theme is defined as:

style:
  body:
    fgColor: white
    bgColor: black
    secondaryTextColor: yellow
    tertiaryTextColor: green
    borderColor: white
  stat_table:
    keyFgColor: yellow
    valueFgColor: white
    logoColor: yellow
  proc_table:
    fgColor: lightskyblue
    fgWarning: yellow
    fgPending: grey
    fgCompleted: lightgreen
    fgError: red
    headerFgColor: white
  help:
    fgColor: black
    keyColor: white
    hlColor: green
    categoryFgColor: lightskyblue
  dialog:
    fgColor: cadetblue
    bgColor: black
    buttonFgColor: black
    buttonBgColor: lightskyblue
    buttonFocusFgColor: black
    buttonFocusBgColor: dodgerblue
    labelFgColor: yellow
    fieldFgColor: black
    fieldBgColor: lightskyblue

theme.yaml can contain only the values you wish to change, default values will be used for the rest.
For example if you want to change the default background color to green instead of black and the logo color to blue, the configuration will be as follows:

style:
  body:
    bgColor: green
  stat_table:
    logoColor: blue

💡 To apply the new values it's enough to select the Custom Style (F shortcut) theme from the theme selector menu (CTRL-T).

For Color names W3C approved color names should be used. Note that on various terminals colors may be approximated, or not supported at all. If no suitable representation for a color is known, the no color will be set, deferring to whatever default attributes the terminal uses.

By default process-compose will respect any theme used in your terminal which might result in less accurate color fidelity. To force the use of "True Colors", please use the HEX color notation:

style:
  body:
    bgColor: '#00FF00' #green
  stat_table:
    logoColor: '#0000FF' #blue

TUI State Settings

TUI will automatically save its state when the after changing the following:

  1. TUI Theme
  2. Processes sort column
  3. Processes sort order (ascending / descending)

settings.yaml file location $XDG_CONFIG_HOME/process-compose/

Settings Structure

#XDG_CONFIG_HOME/process-compose/settings.yaml

theme: Cobalt
sort:
    by: NAME
    isReversed: false

💡 The auto save feature can be disabled by using the --read-only flag.
