We’ve recently released a new version of the Completion Predictor! We’ve been highlighting
this predictor when showing off some of the new improvements in the
PSReadLine 2.3.x betas and wanted to share some of the awesome things you can do with this
Completion Predictor v0.1.1
If you are unfamiliar with the Completion Predictor, this is a plugin in predictor that we released
last year that provides tab completion to help give prediction results. This means it can work for
helping fill out parameters of cmdlets and properties and methods of objects. The Version 0.1.1
release contains some experience improvements and some new completion capabilities.
Installing Completion Predictor v0.1.1
First and foremost, how can you get this predictor? The release is available from the
Use the following command to install CompletionPredictor using PowerShellGet v2.x:
Install-Module -Name CompletionPredictor
If you are using PowerShellGet v3, you can use the following command:
Install-PSResource -Name CompletionPredictor
Argument Completion Improvements
cd and dir
Using tab completion we’re able to give predictions on the next folders you may want to navigate to
cd or view the contents of with
Another argument completion improvement was with
git. These are improvements that we’ve found
works best for our workflow but may help with your
git workflow as well!
Completion Predictor is able to look at remote and local branches available to accelerate your flow
git merge. Here is an example of it working.
Checking out and deleting branches
Similarly, to the merge behavior, the completion predictor is now able to give predictions on what
branch you may want to use when checking out or deleting branches. This only works with the
git checkout and
git branch -D. The predictor intentionally doesn’t include the
current branch you are in when giving results.
As I mentioned, we added these improvements to help with our specific
git workflows. Typically, the
rough flow we’ve is the following:
git fetch --all -p-> to get the latest changes in that repo
git merge-> sync the default branch
git branch -D-> delete the old working branches that were already removed from the remote side
git checkout-> checkout a new branch to work in
git push-> push the new branch to remote to then create a PR
This isn’t a blog post about how to best use
git, so please refer to other online resources to
git. This is just the workflow we like to use that helped us create the
to the Completion Predictor.
You can find the rest of the changes in this release in the changelog on the release page. We
love getting feedback on these predictors we make! The entire source code for this predictor is
available on GitHub and can be a great starting point for making your own predictor! Please
feel free to open issues or PRs on the GitHub page for improvements that may work for you and
