プロジェクトの歴史

Jonathan Slenders created pyvim after developing prompt-toolkit. Once prompt-toolkit had enough primitives for full-screen terminal interfaces, a small editor prototype became a way to test the toolkit's architecture and demonstrate its flexibility.

The project implemented Vim-like modes, windows, tabs, search and editor settings while integrating Python-oriented features such as Pygments highlighting, Jedi completion, and asynchronous Pyflakes checking. The official README also records performance and feature limitations relative to Vim.

採用の歴史

pyvim was published as a Python package and later entered Homebrew. Its repository attracted substantial interest as both an editor experiment and a demonstration of prompt-toolkit, although the official documentation continues to describe important limitations compared with Vim.

使われ方

Users launch `pyvim` as a terminal editor and can alias `vi` or set the `EDITOR` environment variable to it. A `.pyvimrc` file can provide Python-based customization.

The official README cautions that pyvim remains less capable than Vim, particularly for large files and features such as folding and macros. It is therefore especially useful for experimentation with Python terminal UI and editor extensions.

パッケージ好きにとっての重要性

pyvim is notable less as a drop-in Vim replacement than as a proof that a full-screen, modal terminal editor could be built in pure Python on prompt-toolkit. It exposed editor requirements that could feed improvements back into the underlying toolkit and related Python terminal applications.

タイムライン

• Origins: pyvim began as a small proof of concept after prompt-toolkit gained the components needed for a full-screen editor.
• Development: Vim-like splits, tabs, settings, syntax highlighting, completion, and code checking were implemented.
• Package adoption: pyvim became installable through Python packaging and Homebrew.
