Oct 13, 2025 by wbrum.org 103 views

Introduction

Helm is a powerful Emacs package that provides an interactive way to complete and navigate through files, buffers, and other Emacs objects. While it can be incredibly useful, it can also be overwhelming and intrusive at times. If you're like many Emacs users, you might want to disable Helm's file completion for interactive shell commands, but still keep it enabled for other purposes. In this article, we'll explore how to achieve this.

Understanding Helm Mode

Before we dive into disabling Helm's file completion for interactive shell commands, let's quickly understand how Helm mode works. Helm mode is a minor mode in Emacs that provides an interactive way to complete and navigate through files, buffers, and other Emacs objects. When Helm mode is enabled, Emacs will display a completion buffer at the bottom of the screen, showing a list of possible completions for the current input.

Disabling Helm File Completion for Interactive Shell Commands

To disable Helm's file completion for interactive shell commands, you'll need to customize the helm-completion-system variable. This variable determines which completion system to use for interactive shell commands. By default, Helm uses the helm-completion-system variable to determine whether to use Helm's completion system or the default Emacs completion system.

To disable Helm's file completion for interactive shell commands, you can add the following code to your Emacs configuration file:

(custom-set-variables
 '(helm-completion-system 'default))

This will tell Helm to use the default Emacs completion system for interactive shell commands, effectively disabling Helm's file completion for these commands.

Restoring Default Emacs Behavior for File Completion

If you want to restore the default Emacs behavior for file completion, you can use the helm-completion-system variable to set the completion system to default. This will disable Helm's file completion for all commands, including interactive shell commands.

To restore the default Emacs behavior for file completion, you can add the following code to your Emacs configuration file:

(custom-set-variables
 '(helm-completion-system 'default))

This will tell Helm to use the default Emacs completion system for all commands, effectively disabling Helm's file completion.

Customizing Helm's Completion System

If you want to customize Helm's completion system for specific commands or modes, you can use the helm-completion-system variable to set the completion system for those commands or modes. For example, you can set the completion system to helm for the find-file command, while setting it to default for interactive shell commands.

To customize Helm's completion system for specific commands or modes, you can add the following code to your Emacs configuration file:

(custom-set-variables
 '(helm-completion-system 'helm)
 '(helm-completion-system 'default))

This will tell Helm to use the Helm completion system for the find-file command, while using the default Emacs completion system for interactive shell commands.

Conclusion

In this article, we've explored how to disable Helm's file completion for interactive shell commands, while still keeping it enabled for other purposes. We've also discussed how to restore the default Emacs behavior for file completion and how to customize Helm's completion system for specific commands or modes. By following the steps outlined in this article, you can customize Helm's behavior to suit your needs and preferences.
