xonsh/xonsh 0.9.19

on GitHub

Added:

• history command now supports flush action

• Added new items on "Bash to xsh" page

• JsonHistory: added history gc --force switch to allow user to override above warning.

• JsonHistoryGC: display following warning when garbage collection would delete "too" much data and don't delete anything.

  "Warning: History garbage collection would discard more history ({size_over} {units}) than it would keep ({limit_size}).\n"
  "Not removing any history for now. Either increase your limit ($XONSH_HIST_SIZE), or run history gc --force.",

  It is displayed when the amount of history on disk is more than double the limit configured (or defaulted) for $XONSH_HIST_SIZE.

• $LS_COLORS code 'mh' now recognized for (multi) hard-linked files.

• $LS_COLORS code 'ca' now recognized for files with security capabilities (linux only).

• CI step to run flake8 after pytest.

• RichCompletion for completions with different display value, description and prefix_len.

• Allow completer access to multiline document when available via xonsh.completers.tools.get_ptk_completer().current_document.

• abbrevs word expasion can now be reverted by pressing
  the space bar second time immediately after the previous
  word got expanded.

• ulimit command.

• pdb xontrib, that runs pdb debugger on reception of SIGUSR1 signal.

• xontrib-xpg is a xontrib for running or explaining sql queries for posgresql database.

Changed:

• Xonsh now launches subprocesses with their argv[0] argument containing
  the command exactly as inserted by the user instead of setting it to the
  resolved path of the executable. This is for consistency with bash and other
  shells.
• Added ability to register, deregister environment variables;
  centralized environment default variables
• Added exit to the "Bash to xsh" article.
• xonsh.main _failback_to_other_shells now tries user's login shell (in $SHELL) before trying system wide shells from /etc/shells.
• The current working directory is now correctly obtained in line 501 of xonsh/parsers/base.py
• Garbage collection avoids deleting history and issues a warning instead if existing history is more than double the comfigured limit.
  This protects active users who might have accumulated a lot of history while a bug was preventing garbage collection. The warning
  will be displayed each time Xonsh is started until user takes action to reconcile the situation.
• tests\test_integrations.py no longer runs with XONSH_DEBUG=1 (because new, debug-only progress messages from history were breaking it).
• Updated pytest_plugin for pytest 5.4 API, pip requirements for pytest>= 5.4
• Major improvements to Jedi xontrib completer:
  • Use new Jedi API
  • Replace the existing python completer
  • Create rich completions with extra info
  • Use entire multiline document if available
  • Complete xonsh special tokens
  • Be aware of _ (last result)
  • Only show dunder attrs when prefix ends with '_'
• Many files are starting to be formatted using pyupgrade --py36-plus, in order to automatically update to newer
  Python constructs.
• xontrib load does not stop loading modules on error any more.

Deprecated:

• pytest --flake8 now exits with error message to use flake8 instead.
  Allows single list of lint exceptions to apply in CI and your IDE.

Removed:

• Removed history replay
• pytest-flake8 package from requirements*.txt
• Xonsh now relies exclusively on Setuptools for install.
• Compatibility with Python 3.5 has been removed as well as all related code. In
  particular xonsh.inspector does not defined getouterframes anymore, use
  inspect.getouterframe directly.

Fixed:

• Unhandled exception triggered by unexpected return from callable alias.

• Fix path completer throwing exception sometimes

• Fixed help operator not displaying definition for callables.

• JsonHistory.files(): Now once again enumerates history files from the directory. This has been broken for about 2 years.

• JsonHistory.run_gc(): Don't busy loop while waiting for history garbage collection to complete, sleep a bit instead.
  This does much to keep Xonsh ptk_shell responsive when dealing with very large history on disk.

• Fixed JSON history indexing error.

• Fixed syntax error in scripts containing line continuation syntax.

• $LS_COLORS code 'fi' now used for "regular files", as it should have been all along. (was 'rs')
  See (#3608)[https://github.com//issues/3608].

• pyghooks.color_files now follows implememntation of ls --color closely. Thanks @qwenger!
  However, a few documented differences remain due to use in Xonsh.

• $LS_COLORS['ln'] = 'target' now works. Also fixes #3578.

• Fixed exit code for commands executed via -c (#3402)

• Logical subprocess operators now work after long arguments (e.g. --version).

• pip completer no longer erroneously fires for pipx

• Updated development guide to reference flake8 instead of pylint

• Corrected flake8 config for allowed exceptions.

• various pytest warnings in a "clean" test run.

• The current Mercurial topic is shown.

• Fixed import problems due to modules using deprecated pkg_resources methods by proxying calls to the underlying loader.

• Typo in 'source' alias.

• Crash in 'completer' completer.

• Don't complete unnecessarily in 'base' completer

• Viewing mock objects in the shell

• Fixed formatting error in vox rm command.
