Hi all,
Where is<localleader> defined? How would I define a similar variable called
<voleader> so that it's available for use in various Vimscript programs?
Thanks

See the following, at :help <Leader> and :help <LocalLeader>:
*<Leader>* *mapleader*
To define a mapping which uses the "mapleader" variable, the special string
"<Leader>" can be used. It is replaced with the string value of "mapleader".
If "mapleader" is not set or empty, a backslash is used instead. Example: >
:map <Leader>A oanother line<Esc>
Works like: >
:map \A oanother line<Esc>
But after: >
:let mapleader = ","
It works like: >
:map ,A oanother line<Esc>
Note that the value of "mapleader" is used at the moment the mapping is
defined. Changing "mapleader" after that has no effect for already defined
mappings.
*<LocalLeader>* *maplocalleader*
<LocalLeader> is just like <Leader>, except that it uses "maplocalleader"
instead of "mapleader". <LocalLeader> is to be used for mappings which are
local to a buffer. Example: >
:map <LocalLeader>q \DoItNow
<
In a global plugin <Leader> should be used and in a filetype plugin
<LocalLeader>. "mapleader" and "maplocalleader" can be equal. Although, if
you make them different, there is a smaller chance of mappings from global
plugins to clash with mappings for filetype plugins. For example, you could
keep "mapleader" at the default backslash, and set "maplocalleader" to an
underscore.
IOW, if you
:let maplocalleader = '_'
then from now on, any _new_ mappings defined with <LocalLeader> will use
an underscore for it, instead of the default backslash.
Whenever a new macro is defined, if it is written with <Leader> in it,
Vim replaces that symbol with the value of the variable named mapleader
(or a backslash if empty or undefined), and if it uses <LocalLeader>,
Vim uses the value of maplocalleader (or a backslash if empty or undefined).
If you later change one or both of hese variables, already defined
mappings are unaffected; the value used is always the value at the time
the mapping is *defined*.
Best regards,
Tony.
