Tips

About the completion trigger key

• PSCompletions uses the Tab key by default.
• You can set it by running psc menu config trigger_key <key>.

About completion update

• When PSCompletions module is imported after starting PowerShell, it will start a background job to check for the completion status of the remote repository.
• After getting the update, PSCompletions will show the latest status of the completions in the next time.

About completion menu

• In addition to the built-in completion menu of PowerShell, PSCompletions module also provides a more powerful completion menu.

  • Setting: psc menu config enable_menu 1 (Default: 1)

• The module's completion menu is based on PS-GuiCompletion realization idea, thanks!

• Available Windows environment:

  • PowerShell
  • Windows PowerShell
    • Due to rendering problems of Windows PowerShell, the border style of the completion menu cannot be customized.
      • If you need to customize it, use PowerShell.

• Some keys in the module's completion menu.

  1. Apply the selected completion item: Enter

     • You can also use Tab or Space when there's only one completion.

  2. Delete filter characters: Backspace

  3. Exit the completion menu: Esc / Ctrl + c

     • You can also use Backspace when there're no characters in the filter area.

  4. Select completion item:

     Select previous item	Select next item
     Up	Down
     Left	Right
     Shift + Tab	Tab
     Shift + Space	Space
     Ctrl + u	Ctrl + d
     Ctrl + p	Ctrl + n

• All configurations of it, you can trigger completion by running psc menu, then learn about them by the completion tip.

  • For configured values, 1 means true and 0 means false. (It applies to all configurations of PSCompletions)

About menu enhance

• Setting: psc menu config enable_menu_enhance 1 (Default: 1)

• Now, PSCompletions has two completion implementations.

  1. Register-ArgumentCompleter
     • : It's used.
     • : It's optional.
       • You can use it by running psc menu config enable_menu_enhance 0.
       • It's not recommended. It only works for completions added by psc add.
  2. Set-PSReadLineKeyHandler
     • : It's used by default.
       • Requires: enable_menu and enable_menu_enhance both set to 1.
     • It no longer needs to loop through registering Register-ArgumentCompleter for all completions, which theoretically makes loading faster.
     • It use TabExpansion2 to manage completions globally, not limited to those added by psc add.
       • For example:
         • Path completion such as cd/.\/..\/~\/... in PowerShell.
         • Build-in commands such as Get-*/Set-*/New-*/... in PowerShell.
         • Completion registered by Register-ArgumentCompleter
         • Combined with argc-completions.
         • Completion registered by cli or module.
         • ...

About special symbols

Note

• Due to future changes in Windows Terminal, 😄🤔😎 will not be displayed properly in the completion menu, so these three default special symbols will change.
• Related issue: microsoft/terminal#18242
• The changes are as follows:
  • 😄 => →
  • 🤔 => ?
  • 😎 => ↓

• Special symbols after the completion item are used to let you know in advance if completions are available before you press the Tab key.

  • They only exist in completions added via psc add.
  • You can hide them by replacing them with the empty string.
    • psc menu symbol SpaceTab ""
    • psc menu symbol OptionTab ""
    • psc menu symbol WriteSpaceTab ""

• →,?,↓ : If there are multiple, you can choose the effect of one of them.

  • Define them:
    • Normal Completion: Sub-commands. Such as add/pull/push/commit/... in git.
    • Optional Completion: Optional parameters. Such as -g/-u/... in git add.
    • General Optional Completion: General optional parameters that can be used with any command. Such as --help/... in git.
  • → : It means that after you apply it, you can press Space and Tab key to continue to get Normal Completion or Optional Completion.
    • It will appear only when there's Normal Completion or Optional Completion.
    • It can be customized by running psc menu symbol SpaceTab <symbol>
  • ? : It means that after you apply it (Optional Completion), you can press Space and Tab key to continue to get other Optional Completion.
    • General Optional Completion use also this symbol.
    • It can be customized by running psc menu symbol OptionTab <symbol>
  • ↓ : It means that after you apply it (Optional Completion or General Optional Completion), you can press Space and enter a string, then press Space and Tab key to continue to get other Optional Completion or General Optional Completion.
    • If the string has Spaces, Please use "(quote) or '(single quote) to wrap it. e.g. "test content"
    • If there's also →, it means that there's Normal Completion, you can press Space and Tab key to continue to get them without entering a string.
    • It can be customized by running psc menu symbol WriteSpaceTab <symbol>
  • All completions can be triggered by pressing the Tab key after entering a part.

About completion tip

• The completion tip is only a helper, you can also disable the tip by running psc menu config enable_tip 0

  • To enable the completion tip, run psc menu config enable_tip 1.
  • You can also disable the tip for a specific completion, such as psc.
    • psc completion psc enable_tip 0

• General structure of the completion tip: Usage + Description + Example

  U: install|add [-g|-u] [options] <app>
  This is a description of the command.
  E: install xxx
     add -g xxx

• Example Analysis:

  1. Usage: Begin with U:
     • command name: install
     • command alias: add
     • required parameters: <app>
       • app is a simple summary of the parameters.
     • optional parameters: -g -u
       • [options]: Some options.
  2. Description: The description of the command.

About language

• Global language: Default to the language of current system.
  • You can show it by running psc config language.
  • You can change it by running psc config language zh-CN.
• Completion language: The language set for the specified completion.
  • e.g. psc completion git language en-US.
• Available language: In the completion config.json file, there is a language attribute whose value is a list of available languages.

Determine language

1. Get the specified language:
   • If there is Completion language,use it.
   • If not, use Global language.
2. Determine the final language:
   • Determine whether the value of the first step exists in Available language.
   • If it exists, use it.
   • If not, use the first of the Available language. (It's usually en-US)

About path completion

• Take git for example, when entering git add, pressing the Space and Tab keys, path completion will not be triggered, only completion provided by the module will be triggered.
• If you want to trigger path completion, you need to enter a content which matches ^(?:\.\.?|~)?(?:[/\\]).*.
• e.g.
  • Please enter ./ or .\ and press Tab key to get path completion for the subdirectory or file.
  • Please enter ../ or ..\ and press Tab key to get path completion for the parent directory or file.
  • Please enter / or \ and press Tab key to get path completion for the sibling directory.
  • More examples: ~/ / ../../ ...
• So you can enter git add ./ and then press Tab key to get the path completion.
