|
||||
HOOKS *argwrap-hooks*
|
||||
|
||||
It is possible to hook before or after a wrap/unwrap operation using
|
||||
autoloaded functions, the hooks are named:
|
||||
- `pre_wrap`
|
||||
- `pre_unwrap`
|
||||
- `post_wrap`
|
||||
- `post_unwrap`
|
||||
|
||||
For example to do something after any wrap create a function: >
|
||||
argwrap#hooks#my_hook#post_wrap(range, container, arguments)
|
||||
<
|
||||
It is also possible to create a hook for a specific filetype: >
|
||||
argwrap#hooks#filetype#vim#my_hook#post_wrap(range, container, arguments)
|
||||
<
|
||||
|
||||
Global hooks are loaded on the first time a wrap/unwrap operation is done.
|
||||
Filetype hooks however are only loaded for the current filetype.
|
||||
You can see the list of loaded hooks with: >
|
||||
echo g:argwrap_global_hooks
|
||||
echo g:argwrap_filetype_hooks
|
||||
echo b:argwrap_hooks
|
||||
<
|
||||
The hooks are loaded from any directory specified in the |runtimepath|.
|
||||
Global hooks will be executed before filetype ones.
|
||||
Global and filetype hooks are sorted by the |globpath()| function. Meaning you
|
||||
can control the execution order of the hooks by prefixing them with a
|
||||
priority.
|
||||
Post hooks order is reversed in order to keep the execution order logical.
|
||||
|
||||
For example if there two hooks named `000_cursor` and `200_anything` , the
|
||||
cursor hook being responsible to preserve the cursor position it must be
|
||||
executed first to ensure no modification of the cursor position has been done
|
||||
yet so it receive the lowest priority.
|
||||
The execution stack for a wrap operation would then be:
|
||||
- `000_cursor#pre_wrap`
|
||||
- `000_anything#pre_wrap`
|
||||
- `wrap operation`
|
||||
- `000_anything#post_wrap`
|
||||
- `000_cursor#post_wrap`
|
||||
|
||||
|
||||
An important things to know when writing a new hook is that calling an
|
||||
|autoload| function which does not exist will source the file that should
|
||||
contain the function every time.
|
||||
So even if you do not need one of the hook, always define them all. This is a
|
||||
