Kakoune
|
|
=======
|
|
|
|
Introduction:
|
|
-------------
|
|
|
|
Kakoune is a code editor heavily inspired by vim, as such most of it's
|
|
commands are similar to vi's ones.
|
|
|
|
Kakoune can operate in two modes, normal and insertion. In insertion mode,
|
|
keys are directly inserted into the current buffer. In normal mode, keys
|
|
are used to manipulate the current selection and to enter insertion mode.
|
|
|
|
There is no concept of cursor in kakoune, only selections, a single character
|
|
selection can be seen as a cursor but there is no difference internally.
|
|
|
|
Building
|
|
--------
|
|
|
|
Kakoune dependencies are:
|
|
|
|
* GCC >= 4.6
|
|
* boost
|
|
* ncurses
|
|
|
|
To build, just type *make* in the src directory
|
|
|
|
Basic Movement
|
|
--------------
|
|
|
|
* _space_: select the character under selection end
|
|
|
|
* _h_: select the character on the right of selection end
|
|
* _j_: select the character below the selection end
|
|
* _k_: select the character above the selection end
|
|
* _l_: select the character on the left of selection end
|
|
|
|
* _w_: select the word and following whitespaces on the right of selection end
|
|
* _b_: select preceding whitespaces and the word on the left of selection end
|
|
* _e_: select preceding whitespaces and the word on the right of selection end
|
|
|
|
* _x_: select line on which selection end lies (or next line when end lies on
|
|
an end-of-line)
|
|
* _alt-x_: expand selections to contain full lines (including end-of-lines)
|
|
|
|
* _%_: select whole buffer
|
|
|
|
* _alt-H_: select to line begin
|
|
* _alt-L_: select to line end
|
|
|
|
Appending
|
|
---------
|
|
|
|
for most selection commands, using shift permits to add to current selection
|
|
instead of replacing it. for example, _wWW_ selects 3 consecutive words
|
|
|
|
Using Counts
|
|
------------
|
|
|
|
Most selection commands also support counts, which are entered before the
|
|
command itself.
|
|
|
|
for example, _3W_ selects 3 consecutive words and _3w_ select the third word on
|
|
the right of selection end.
|
|
|
|
Changes
|
|
-------
|
|
|
|
* _i_: insert before current selection
|
|
* _a_: insert after current selection
|
|
* _d_: yank and delete current selection
|
|
* _c_: yank and delete current selection and insert
|
|
|
|
* _I_: insert at current selection begin line start
|
|
* _A_: insert at current selection end line end
|
|
* _o_: insert in a new line below current selection end
|
|
* _O_: insert in a new line above current selection begin
|
|
|
|
* _p_: paste after current selection end
|
|
* _P_: paste before current selection begin
|
|
|
|
* _alt-j_: join selected lines
|
|
|
|
* _|_: pipe each selections through the given external filter program
|
|
and replace with it's output.
|
|
|
|
Multi Selection
|
|
---------------
|
|
|
|
Kak was designed from the start to handle multiple selections.
|
|
On way to get a multiselection is via the _s_ key.
|
|
|
|
For example, to change all occurences of word 'roger' to word 'marcel'
|
|
in a paragraph, here is what can be done:
|
|
|
|
select the paragraph with enough _x_. press _s_ and enter roger then enter.
|
|
now paragraph selection was replaced with multiselection of each roger in
|
|
the paragraph. press _c_ and marcel<esc> to replace rogers with marcels.
|
|
|
|
A multiselection can also be obtained with _Alt-s_, which splits the current
|
|
selection according to the regex entered. To split a comma separated list,
|
|
use _alt-s_ then ', *'
|
|
|
|
To clear multiple selections, use _space_.
|
|
|
|
Registers
|
|
---------
|
|
|
|
registers are named list of text. They are used for various purpose, like
|
|
storing the last yanked test, or the captures groups associated with the
|
|
last selection.
|
|
|
|
While in insert mode, ctrl-r followed by a register name (one character)
|
|
inserts it.
|
|
|
|
For example, ctrl-r followed by " will insert the currently yanked text.
|
|
ctrl-r followed by 2 will insert the second capture group from the last regex
|
|
selection.
|
|
|
|
Registers are lists, instead of simply text in order to interact well with
|
|
multiselection. Each selection have it's own captures, or yank buffer.
|
|
|
|
Highlighters
|
|
------------
|
|
|
|
Manipulation of the displayed text is done through highlighters, which can be added
|
|
or removed with the command :addhl <highlighter_name> <highlighter_parameters...>
|
|
and :rmhl <highlighter_id>
|
|
|
|
existing highlighters are:
|
|
|
|
* *highlight_selections*: used to make current selection visible
|
|
* *expand_tabs*: expand tabs to next 8 multiple column (to make configurable)
|
|
* *number_lines*: show line numbers
|
|
* *regex*: highlight a regex, takes 3 parameters <regex> <fg_color> <bg_color>
|
|
* *group*: highlighter group, containing other highlighters. takes one
|
|
parameter, <group_name>. useful when multiple highlighters work
|
|
together and need to be removed as one. Adding and removing from
|
|
a group can be done using
|
|
:addgrouphl <group> <highlighter_name> <highlighter_parameters...>
|
|
:rmgrouphl <group> <highlighter_name>
|
|
|
|
Filters
|
|
-------
|
|
|
|
Filters can be installed to interact with buffer modifications. They can be
|
|
added or removed with :addfilter <filter_name> <filter_parameters...> and
|
|
:rmfilter <filter_id>
|
|
|
|
exisiting filters are:
|
|
|
|
* *preserve_indent*: insert previous line indent when inserting a newline
|
|
* *cleanup_whitespaces*: remove trailing whitespaces on the previous line
|
|
when inserting an end-of-line.
|
|
* *expand_tabulations*: insert spaces instead of tab characters
|
|
|
|
Hooks
|
|
-----
|
|
|
|
commands can be registred to be executed when certain events arise.
|
|
to register a hook, use the hook command.
|
|
|
|
:hook <scope> <hook_name> <filtering_regex> <command> <command_args>...
|
|
|
|
<scope> can be either global or window, as hooks can be registered per
|
|
window.
|
|
|
|
for example, to automatically use line numbering with .cc files,
|
|
use the following command:
|
|
|
|
:hook global WinCreate .*\.cc addhl number_lines
|
|
|
