git is the preferred way to install. The plugin ends up contained in its own
directory, and updates are just a
git pull away.

CoffeeMake: Compile the Current File
CoffeeMake command compiles the current file and parses any errors:
The full signature of the command is:
:[silent] CoffeeMake[!] [COFFEE-OPTIONS]...
CoffeeMake shows all compiler output and jumps to the first line
reported as an error by
Compiler output can be hidden with
Line-jumping can be turned off by adding a bang:
Options given to
CoffeeMake are passed along to
Recompile on write
To recompile a file when it is written, add an
autocmd like this to your
au BufWritePost *.coffee silent CoffeeMake!
All of the customizations above can be used, too. This one compiles silently
and with the
-b option, but shows any errors:
au BufWritePost *.coffee silent CoffeeMake! -b | cwindow | redraw!
redraw! command is needed to fix a redrawing quirk in terminal vim, but
can removed for gVim.
Default compiler options
CoffeeMake command passes any options in the
variable along to the compiler. You can use this to set default options:
let coffee_make_options = "--bare"
CoffeeCompile: Compile Snippets of CoffeeScript
CoffeeCompile command shows how the current file or a snippet of
:[RANGE] CoffeeCompile [watch|unwatch] [vert[ical]] [WINDOW-SIZE]
CoffeeCompile without a range compiles the whole file:
CoffeeCompile with a range, like in visual mode, compiles the selected
snippet of CoffeeScript:
This scratch buffer can be quickly closed by hitting the
vert splits the CoffeeCompile buffer vertically instead of horizontally:
The initial size of the CoffeeCompile buffer can be given as a number:
Watch (live preview) mode
Watch mode brings to vim the "Try CoffeeScript" live preview box on the CoffeeScript homepage (or something like it):
watch to start watching a buffer (
vert is also recommended):
:CoffeeCompile watch vert
After making some changes in insert mode, hit escape and the CoffeeScript will
be recompiled. Changes made outside of insert mode don't trigger this recompile,
CoffeeCompile will compile these changes without any bad effects.
To get synchronized scrolling of a CoffeeScript and CoffeeCompile buffer, set
scrollbind on each:
unwatch to stop watching a buffer:
CoffeeRun: Run some CoffeeScript
CoffeeRun command compiles the current file or selected snippet and runs
You can configure plugin behavior by adding the relevant lines to your
Disable trailing whitespace error
Trailing whitespace is highlighted as an error by default. This can be disabled with:
hi link coffeeSpaceError NONE
Disable trailing semicolon error
hi link coffeeSemicolonError NONE
Disable reserved words error
Reserved words like
var are highlighted as an error where
they're not allowed in CoffeeScript. This can be disabled with:
hi link coffeeReservedError NONE
Tuning Vim for CoffeeScript
Changing these core settings can make vim more CoffeeScript friendly.
Fold by indentation
Folding by indentation works well for CoffeeScript functions and classes:
To fold by indentation in CoffeeScript files, add this line to your
au BufNewFile,BufReadPost *.coffee setl foldmethod=indent nofoldenable
With this, folding is disabled by default but can be quickly toggled per-file
zi. To enable folding by default, remove
au BufNewFile,BufReadPost *.coffee setl foldmethod=indent
To get standard two-space indentation in CoffeeScript files, add this line to
au BufNewFile,BufReadPost *.coffee setl shiftwidth=2 expandtab
