Modularized Bash-Completion

Summary

Modularize bash-completion package.

Owner

Current status

  • Targeted release: Fedora 12
  • Last updated: 2009-06-05
  • Percentage of completion: 20%

Bash-completion is the niftiest thing since Fedora itself. The implementation sucks though: Every interactive shell sources 200kb of shell scripts and keeps it in memory, consuming lots of memory, slowing startup down, and cluttering "set" output. We'll modularize it to make it both more maintainable and more efficient.

Detailed Description

See 475229 for details.

Benefit to Fedora

Reduced memory consumption: currently any interactive shell takes 200kb to load completion commands. It also takes considerable time (0.3 seconds?!). These are perhaps two reasons why bash-completion is not installed by default. We'll fix these.

Scope

Bash needs to be extended to add a "catch-all" completion handler. That's tracked in 475229.

We also need to modularize the bash-completion package. There's an external project for that already [1]. We need to work with them to make it use the "catch-all" handler when available.

How To Test

TBD.

User Experience
