Coqtail enables interactive Coq proof development in Vim similar to CoqIDE or ProofGeneral.
It supports:
- Coq 8.4 - 8.9
- Having multiple Coq buffers open
- Python 2 and 3
As a vim package:
mkdir ~/.vim/pack/coq/start
git clone https://github.com/let-def/vimbufsync.git ~/.vim/pack/coq/start/vimbufsync
git clone https://github.com/whonore/coqtail.git ~/.vim/pack/coq/start/coqtail
vim +helptags\ .vim/pack/coq/start/coqtail/doc +qUsing pathogen:
cd ~/.vim/bundle && git clone https://github.com/whonore/coqtail.git
Using Vundle:
Plugin 'whonore/coqtail' (in .vimrc)
:PluginInstall
Using VimPlug:
Plug 'whonore/coqtail' (in .vimrc)
:PlugInstall
Coqtail requires:
If you are using pathogen, documentation can be generated by
:call pathogen#helptags(). Alternatively, you can do :helptags {path-to-coqtail}/doc.
Coqtail provides the following commands (see :help coqtail for more details):

{n}CoqUndo |
<leader>ck |
Step back n (1 by default) sentences. |

Coq <args> |
Send arbitrary queries to Coq (e.g. Check, About, Print, etc.). |
|
Coq Check <arg> |
<leader>ch |

Coq Locate <arg> |
<leader>cf |
Show where <arg> is defined. |
Coq SearchAbout <args> |
<leader>cs |

The mappings shown above are set by default, but you can disable them all and
define your own by setting g:coqtail_nomap = 1 in your .vimrc.
Alternatively, you can choose to only remap specific commands and the defaults
will still be used for the rest.
Coqtail also comes with an ftdetect script for Coq, as well as modified
versions of Vincent Aravantinos'
syntax and
index scripts for Coq.
These scripts are used by default but can be disabled by setting
g:coqtail_nosyntax = 1 and g:coqtail_noindent = 1 respectively.
