configurable: True

default: False

store_as_str: False


$RIGHT_PROMPT

Template string for right-aligned text at the prompt. This may be parametrized in the same way as the $PROMPT variable. Currently, this is only available in the prompt-toolkit shell.

    user’s system

To use the prompt_toolkit shell you need to have the prompt_toolkit library installed. To specify which shell should be used, do so in the run control file.

default: 3

store_as_str: False


$SUPPRESS_BRANCH_TIMEOUT_MESSAGE

Whether or not to suppress branch timeout warning messages.

configurable: True

default: False

store_as_str: False


$TERM

TERM is sometimes set by the terminal emulator. This is used (when valid) to determine whether or not to set the title. Users shouldn’t need to set this themselves. Note that this variable should be set as early as possible in order to ensure it is effective. Here are a few options:

  • Set this from the program that launches xonsh. On POSIX systems, this can be performed by using env, e.g. /usr/bin/env TERM=xterm-color xonsh or similar.
  • From the xonsh command line, namely xonsh -DTERM=xterm-color.
  • In the config file with {"env": {"TERM": "xterm-color"}}.
  • Lastly, in xonshrc with $TERM

Ideally, your terminal emulator will set this correctly but that does not always happen.
