xonsh 0.8.5

on Python PyPI

Added:

• Add alias to base16 shell <https://github.com/chriskempson/base16-shell>_

• Installation / Usage

  1. To install use pip

  .. code-block:: bash

    python3 -m pip install xontrib-base16-shell
  

  1. Add on ~/.xonshrc

  .. code:: python
  :number-lines:

    $BASE16_SHELL = $HOME + "/.config/base16-shell/"
    xontrib load base16_shell
  

  1. See image

• New DumbShell class that kicks in whenever $TERM == "dumb".
  This usually happens in emacs. Currently, this class inherits from
  the ReadlineShell but adds some light customization to make
  sure that xonsh looks good in the resultant terminal emulator.

• Aliases from foreign shells (e.g. Bash) that are more than single expressions,
  or contain sub-shell executions, are now evaluated and run in the foreign shell.
  Previously, xonsh would attempt to translate the alias from sh-lang into
  xonsh. These restrictions have been removed. For example, the following now
  works:

  .. code-block:: sh

  $ source-bash 'alias eee="echo aaa \$(echo b)"'
  $ eee
  aaa b
  

• New ForeignShellBaseAlias, ForeignShellFunctionAlias, and
  ForeignShellExecAlias classes have been added which manage foreign shell
  alias execution.

Changed:

• String aliases will now first be checked to see if they contain sub-expressions
  that require evaluations, such as @(expr), $[cmd], etc. If they do,
  then an ExecAlias will be constructed, rather than a simple list-of-strs
  substitutiuon alias being used. For example:

  .. code-block:: sh

  $ aliases['uuu'] = "echo ccc $(echo ddd)"
  $ aliases['uuu']
  ExecAlias('echo ccc $(echo ddd)\n', filename='<exec-alias:uuu>')
  $ uuu
  ccc ddd
  

• The parse_aliases() function now requires the shell name.

• ForeignShellFunctionAlias now inherits from ForeignShellBaseAlias
  rather than object.

Fixed:

• Fixed issues where the prompt-toolkit v2 shell would print an extra newline
  after Python evaluations in interactive mode.
