Script Roundup: united-front
united-front (GitHub: ardagnir / united-front, License: AGPL v3) by James Kolb is a plugin for syncing registers between instances of Vim. First a server is run with vim --servername name
, and then you can connect other clients to it.
I had a look at the source to see how it works. Whenever one of the events FocusLost
, CursorHold
, or VimEnter
is triggered, a function called SendVimInfo
is run. This function calls remote_expr
which causes UnitedFront_ReadFrontFile
to run on the other instances.
The UnitedFront_ReadFrontFile
function reads .unitedfront
for registers. That file is written by WriteFrontFile
which packs the desired registers based on an array called savedRegs
.
It’s a simple implementation but an interesting use of remote_expr
and file system functions.
