🌠 v1.2.0 - The completions release

Welcome to v1.2.0 of Cobra! This release focuses on code completions, several critical bug fixes, some documentation updates, and security bumps. Upgrading should be simple but note please take note of the introduction of completions V2 and their default use. The v1 completions library is still available, but will be deprecated in the future. Please open an issue with any problems!

New Features

  • Automatically adds completion command for shell completions. If a completion command is already provided, uses that instead. This will automatically provide shell completions for bash, zsh, fish, and PowerShell #1192
    • Users can configure the command auto creation:
      • disable the creation of the completion command
      • disable completion descriptions
      • disable the --no-descriptions flag for "always on" completion descriptions
  • Introduction of bash completions V2, a uniform completion approach which include completion descriptions. The V1 bash completions are still available and will be deprecated in a latter release - #1146
    • Note that projects providing completion through a different command name (say a command named "complete") will continue to use v1 for their own command but will also provide cobra's implicit "completion" command which will use v2, unless of course, these projects take the time to disable the default "completion" command as noted above.
  • Commands now support context being passed to completions - #1265
  • Removed dependency onmitchellh/go-homedir in favor of core Go os.UserHomeDir() - 8eaca5f

  • Bash completion variable leak fix #1352
  • Fish shell completions correctly ignore trailing empty lines #1284
  • PowerShell completions fix for "no file comp directive" - #1363
  • Custom completions now correctly handle multiple shorthand flags together - #1258
  • zsh completions now correctly handle ShellDirectiveCompletionNoSpace and file completion all the time - #1213
  • Multiple fixes / improvements to the fish shell support - #1249
  • Fix home directory config not loading correctly - #1282
  • Fix for RegisterFlagCompletionFunc as a global var not working in multi-threaded programs: #1423
  • Custom completions correctly do not complete flags after args when interspersed is false #1308
