Posh Predictive Text

PowerShell module providing predictive text completions for common CLI tools.

Most people will be familiar with predictive text on mobile phones. Posh-predictive-text brings the same capability to the PowerShell command line interface for common CLI tools used within the software development and data science community.

Modern command line tools are highly configurable and have many parameters. It is difficult to remember them all. Posh Predictive Text improves productivity, not only by providing suggested completions, but also providing a pop-up list of suggestions with tooltips. These tooltips remove the need to break off from enter the command and search documentation for the correct parameter name.

In addition, Posh Predictive Text is also able to suggest a limited number of parameter arguments. For instance when using conda to activate an environment a list of environments is shown.

PoshPredictiveText provides suggested completions in the following situations:

  • When a partial argument is entered and the tab key is pressed. Successive suggestions appear each time the tab key is pressed.

  • Pressing ctrl + space displays a popup list of options with tooltips.

  • If PSReadLine options -PredictionSource is set to use the plugin and -PredictionViewStyle is set to ListView then suggestions will appear below the command line.

Supported Command Line tools

Predictive text is available for the following commands line tools.

  • conda

If a tools is not supported then please consider helping by developing the syntax tree file needed to support it. Further information is available in the developer documentation.


We all love open-source software. It’s the freedom to use it and adapt it as you like. Its the no cost option. However, without funding open-source projects die. If you find this software useful then consider sponsoring the developers. It doesn’t have to be a lot. The cost of a cup of coffee will do. Little contributions help and it is all very much appreciated.
