Access the complete Python official API documentation directly within your editor. Search, browse, and autocomplete Python API documentation using Vim's native :help and :helpgrep commands.

• Browse official Python API documentation without leaving your editor
• Search function signatures, example code, topics, tutorials, and howto guides
• Comprehensive tags database for precise documentation lookup
• High-quality documentation comparable to Dash or Zeal
• Full integration with Vim's help system

Demo uses vimsuggest for autocompletion.

• Vim or Neovim

Install via vim-plug, lazy or Vim's built-in package manager.

Add to your .vimrc:

call plug#begin()
Plug 'girishji/pythondoc.vim'
call plug#end()

Add to your Lua config:

require("lazy").setup({
  { "girishji/pythondoc.vim", opts = {} },
})

git clone https://github.com/girishji/pythondoc.vim.git $HOME/.vim/pack/downloads/opt/pythondoc.vim

Then add this line to your vimrc file:

packadd vimsuggest

git clone https://github.com/girishji/pythondoc.vim.git %USERPROFILE%\vimfiles\pack\downloads\opt\pythondoc.vim

Then add this line to your vimrc file:

packadd vimsuggest

:help <tag>     " Access all helpfiles (Python and Vim)
:Help <tag>     " Python-specific documentation

1. Enable shorthand :h command:

" In vimrc
let g:pythondoc_h_expand = 1

2. Add keyboard shortcut for cursor word lookup:

" In ftplugin/python.vim
exe 'nnoremap <buffer> dK :<c-u>Help <c-r><c-w>'..nr2char(&wildcharm)

• Python tags include @py suffix in Vim (unless helplang is set to py)
• Makes Python documentation easily distinguishable
• Format: function()..topic.pyx (Open the topic by typing :h topic.pyx)

The help files are generated from the official Python repository using the official tool and extension.

Here are the steps to generate help files:

1. Setup:

   # Clone repositories
   git clone https://github.com/girishji/pythondoc.vim
   mkdir tmp
   git clone https://github.com/python/cpython tmp/

2. Create Python Environment:

   cd pythondoc.vim/tmp/cpython/Doc
   make venv

3. Configure Build:

   • Add "vimbuilder" to requirements.txt
   • Set in conf.py: vimhelp_filename_extension = 'pyx'
   • Modify Doc/Makefile:
     • Add 'vimhelp' target (similar to 'html' or 'text')
     • Optional: Comment out Blurb/NEWS lines to avoid harmless errors

4. Prepare Documentation:

   • Rename howto/*.rst files: prepend 'howto-'
   • Update references in (to reflect change of file name):
     • howto/howto-index.rst
     • content.rst

5. Generate Documentation:

   make vimhelp
   cp build/vimhelp/{library,howto}/*.pyx _doc/doc/
   vim "+helptags ./_doc/doc | q"
