Scripting Vim - From Moves to Tools [A Vim Presentation]
Scripting Vim - From Moves to Tools
========================================
* Customizing Vim
* Mappings
* Commands
* Batching with Vim
* Case: plugin
------------------------------------------
" Common Behaviour
Any sufficiently advanced use of Vim
is indistinguishable from scripting.
* Map your common moves
* Create high-level actions as commands
* Compose sequences and flow as functions
------------------------------------------
" Moves: less writing, more *editing*
------------------------------------------
" Pour some Coffee in your JS
console.log("hello", "world")
console.log "hello", "world"
"f(%x``r<Space>b
------------------------------------------
" Macros: just for now
qa...q
@a
"ap
"ay$
------------------------------------------
" Customize Vim
- $VIMRUNTIME
- $HOME/.vim
A plethora of settings
* plugin: options, mappings, commands...
* ftplugin: -||- by filetype (e.g. completion)
* indent, syntax, compiler, spell, colors...
------------------------------------------
" Help
:help
:help <topic, keyword, option, command, function, ...>
