git-weblink 0.1

Produce web link to a commit, file, or line in a repo

git-weblink

This is a command for git that gives you a web link to a commit, file or line(s) in file.

Setup

With pip

Just install it with pip:

pip install git-weblink

Manual setup

Use manual setup in case you don't want to use pip.

Download git_weblink.py, rename it to git-weblink (without the .py extension) and make it globally available by adding a path to it to the PATH variable in your shell. This will make it appear as a git command, and you'll be able to run it like so:

git weblink

Usage

git-weblink can generate various links:

• link to a commit
• link to a file
• link to a line or a line range in file

Links to file or line are always generated as permalinks. There is no option to override this behavior.

Link to a commit

$ git weblink -r HEAD
https://github.com/torvalds/linux/blob/adc218676eef25575469234709c2d87185ca223a/HEAD

$ git weblink -r v6.13
https://github.com/torvalds/linux/commit/d6cb6a3d99adf559a0a404d086f61ee3be866f86

$ git weblink -r 35ff3b0f4596c82ec0a3e1cc43e2a85f5e976023
https://github.com/torvalds/linux/commit/35ff3b0f4596c82ec0a3e1cc43e2a85f5e976023

Link to a file

When no revision specified, the link will be generated for the current HEAD. This means, if you are on a commit that is not pushed yet, the link will be invalid!

$ git weblink include/linux/kernel.h
https://github.com/torvalds/linux/blob/adc218676eef25575469234709c2d87185ca223a/include/linux/kernel.h

Here's a link to the file on a specific revision:

$ git weblink --rev v6.18 include/linux/kernel.h
https://github.com/torvalds/linux/blob/f7b88edb52c8dd01b7e576390d658ae6eef0e134/include/linux/kernel.h

Link to a line or a line range

A link to a line or to a line range can be generated by adding a line number or a line range after the file name:

$ git weblink include/linux/kernel.h:42
https://github.com/torvalds/linux/blob/adc218676eef25575469234709c2d87185ca223a/include/linux/kernel.h#L42

$ git weblink include/linux/compiler.h:248-293
https://github.com/torvalds/linux/blob/adc218676eef25575469234709c2d87185ca223a/include/linux/compiler.h#L248-L293

Integration with (neo)vim

The easiest way to integrate it to vim is to copy-paste the following snippet into your ~/.vimrc (or ~/.config/nvim/init.vim for neovim):

function! s:GitWeblink(line1, line2)
    let l:range = a:line1
    if a:line1 != a:line2
        let l:range .= "-" . a:line2
    endif
    let l:file_with_range = expand('%:.') . ":" . l:range
    let l:cmd = "git weblink -n " . shellescape(l:file_with_range)
    let l:link = system(l:cmd)
    " Copy the link (without a newline) to the system clipboard
    let @+ = trim(l:link)
endfunction

" Run :GitWeblink on a range to get a link
command! -range=% GitWeblink call <SID>GitWeblink(<line1>, <line2>)

" Map GitWeblink for visual mode on "L" key
xmap <silent> L :GitWeblink<cr>

Configuration

Host-specific links

Builtin configuration includes configs for some commonly used hosts (such as github.com, gitlab.com, etc.). But if you are hosting your own git forge, or you are using some corporate repo that you don't want to add into the source, you can put configuration for it into your ~/.gitconfig:

[weblink "https://your-forge.com"]
    commit = "{host}/{repo}/commit/{rev}"
    file = "{host}/{repo}/blob/{rev}/{path}"
    line = "{host}/{repo}/blob/{rev}/{path}#L{line}"
    range = "{host}/{repo}/blob/{rev}/{path}#L{range_begin}-L{range_end}"

Look at HOST_CONFIGS in git-weblink source for some references.

Remote

Another thing to configure is the default remote. Most users don't need to do anything about this. But if you have multiple remotes in your repo, and usually want to get a link to a remote named other than origin, you can either provide the remote name explicitly:

git weblink --remote myremote ...

or you can set the default remote by running this git command:

git config --local weblink.remote myremote

and now myremote will be used by default, without need to provide it explicitly.

For example, consider the following setup for a Linux repo:

$ git remote -v
beagleboard     https://github.com/beagleboard/linux.git (fetch)
beagleboard     https://github.com/beagleboard/linux.git (push)
stable  https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git (fetch)
stable  https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git (push)

and let's say that by default you want to get links to stable repo. In this case just run this:

git config --local weblink.remote stable

and now links will be generated to Linux stable repo:

$ git weblink -r v6.12.63 Makefile
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/Makefile?id=6d8ac7def7031521a56bae29cadece53987bec3c
