Bash completion for pip install

Provides packages names completion in bash for pip install, pip download and pip search

Examples

$ pip install mat<TAB>
Display all 188 possibilities? (y or n)

$ pip install matp<TAB>
matphys                    matplotlib-helpers         matplotlib-subsets
matplotboard               matplotlib-hep             matplotlib-venn
matplotlib                 matplotlib_iterm2          matplotlib_venn_wordcloud
matplotlib2tikz            matplotlib-label-lines     matplotlylib
matplotlib-colorbar        matplotlib-scalebar        matplotsave

Requirements

  • bash
  • curl
  • pip
  • readline

Installation

Source complete.sh from your .bashrc or copy and paste its contents.

Disadvantages

  • keeps a cache of PyPI index (~2MiB) in your home dir (can be moved to /tmp easily)
  • partially breaks pip install options' completion - available only after package name (works normally for other subcommands)
  • not tested with shells other than bash
