----
|
|
highlighters - a
|
|
|
|
Description
|
|
-----------
|
|
|
|
Manipulation of the displayed text is done through highlighters, which can
|
|
be added or removed with the following commands:
|
|
|
|
-------------------------------------------------------
|
|
addhl <highlighter_name> <highlighter_parameters> ...
|
|
-------------------------------------------------------
|
|
|
|
and
|
|
|
|
-----------------------
|
|
rmhl <highlighter_id>
|
|
-----------------------
|
|
|
|
*highlighter_id* is a name generated by the highlighter specified with
|
|
*highlighter_name*, possibly dependent on the parameters. Use command
|
|
completion in a prompt on the *rmhl* command to see the existing highlighters
|
|
ids.
|
|
|
|
General highlighters
|
|
--------------------
|
|
*regex* <ex> <capture_id>:<face> ...::
|
|
highlight a regex, takes the regex as first parameter, followed by
|
|
any number of face parameters. For example:
|
|
|
|
-----------------------------------------------------
|
|
addhl regex //(\hTODO:)?[^\n] 0:cyan 1:yellow,red
|
|
-----------------------------------------------------
|
|
|
|
will highlight C++ style comments in cyan, with an eventual 'TODO:'
|
|
in yellow on red background
|
|
|
|
*dynregex*::
|
|
Similar to regex, but expand (like a command parameter would) the
|
|
given expression before building a regex from the result
|
|
|
|
*flag_lines* <flag> <option_name>::
|
|
add a column in front of text, and display the given flag in it for
|
|
every line contained in the int-list option named <option_name>
|
|
|
|
*show_matching*::
|
|
highlight matching char of the character under the selections cursor
|
|
using MatchingChar face
|
|
|
|
*number_lines* [options]::
|
|
show line numbers, with the following *options*:
|
|
|
|
*-relative*:::
|
|
show line numbers relative to the main cursor line
|
|
|
|
*-hlcursor*:::
|
|
highlight the cursor line with a separate face
|
|
|
|
*-separator* <separator text>:::
|
|
specify a string to separate the line numbers column with
|
|
the rest of the buffer (default is '|')
|
|
|
|
*fill* <face>::
|
|
fill using the given *face*, mostly useful with regions highlighters
|
|
|
|
Highlighting Groups
|
|
-------------------
|
|
|
|
The group highlighter is a container for other highlighters. You can add a
|
|
group to the current window using
|
|
|
|
--------------------
|
|
addhl group <name>
|
|
--------------------
|
|
|
|
The *-group* switch of the *addhl* command provides a mean to add highlighters
|
|
inside this group:
|
|
|
|
----------------------------------------
|
|
addhl -group <name> <type> <params>...
|
|
----------------------------------------
|
|
|
|
Groups can contain other groups, the *-group* switch can be used to define
|
|
a path as follows:
|
|
|
|
--------------------------------------------------
|
|
addhl -group <name> group <subname>
|
|
addhl -group <name>/<subname> <type> <params>...
|
|
--------------------------------------------------
|
|
|
|
Regions highlighters
|
|
--------------------
|
|
|
|
A special highlighter provides a way to segment the buffer into regions,
|
|
which are to be highlighted differently.
|
|
|
|
*name*::
|
|
user defined, used to identify the region
|
|
*opening*::
|
|
regex that defines the region start text
|
|
*closing*::
|
|
regex that defines the region end text
|
|
*recurse*::
|
|
regex that defines the text that matches recursively an end token
|
|
into the region
|
|
|
|
The *recurse* option is useful for regions that can be nested, for example
|
|
the following contruct:
|
|
|
|
----------
|
|
%sh{ ... }
|
|
----------
|
|
|
|
accepts nested braces scopes ('{ ... }') so the following string is valid:
|
|
|
|
----------------------
|
|
%sh{ ... { ... } ... }
|
|
----------------------
|
|
|
|
This region can be defined with:
|
|
|
|
------------------------
|
|
shell_expand %sh\{ \} \{
|
|
------------------------
|
|
|
|
Regions are used in the regions highlighter which can take any number
|
|
of regions.
|
|
|
|
The following command:
|
|
|
|
-----------------------------------------------------------------------
|
|
addhl regions <name> <region_name1> <opening1> <closing1> <recurse1>
|
|
<region_name2> <opening2> <closing2> <recurse2>...
|
|
-----------------------------------------------------------------------
|
|
|
|
defines multiple regions in which other highlighters can be added as follows:
|
|
|
|
---------------------------------------
|
|
addhl -group <name>/<region_name> ...
|
|
---------------------------------------
|
|
|
|
Regions are matched using the left-most rule: the left-most region opening
|
|
starts a new region. When a region closes, the closest next opening start
|
|
another region.
|
|
|
|
That matches the rule governing most programming language parsing.
|
|
|
|
Regions also supports a *-default <default_region>* switch to define the
|
|
default region, when no other region matches the current buffer range.
|
|
|
|
Most programming languages can then be properly highlighted using a regions
|
|
highlighter as root:
|
|
|
|
-----------------------------------------------------------------
|
|
addhl regions -default code <lang> \
|
|
string <str_opening> <str_closing> <str_recurse> \
|
|
comment <comment_opening> <comment_closing> <comment_recurse>
|
|
|
|
addhl -group <lang>/code ...
|
|
addhl -group <lang>/string ...
|
|
addhl -group <lang>/comment ...
|
|
-----------------------------------------------------------------
|
|
|
|
Shared Highlighters
|
|
-------------------
|
|
|
|
Highlighters are often defined for a specific filetype, and it makes then
|
|
sense to share the highlighters between all the windows on the same filetypes.
|
|
|
|
A shared highlighter can be defined with the following command:
|
|
|
|
--------------------------------
|
|
addhl -group /<group_name> ...
|
|
--------------------------------
|
|
|
|
When the group switch values starts with a '/', it references a group in
|
|
the shared highlighters, rather than the window highlighters.
|
|
|
|
The common case would be to create a named shared group, and then fill it
|
|
with highlighters:
|
|
|
|
------------------------------
|
|
addhl -group / group <name>
|
|
addhl -group /name regex ...
|
|
------------------------------
|
|
|
|
It can then be referenced in a window using the ref highlighter.
|
|
|
|
------------------
|
|
addhl ref <name>
|
|
------------------
|
|
|
|
The ref can reference any named highlighter in the shared namespace.
