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.
|
|
|
|
Kakoune has a strong focus on interactivity, most commands provide immediate
|
|
and incremental results, while still being competitive (as in keystroke count)
|
|
with Vim.
|
|
|
|
Kakoune works on selections, which are oriented, inclusive range of characters,
|
|
selections have an anchor and a cursor character. Most commands move both of
|
|
them, except when extending selection where the anchor character stays fixed
|
|
and the cursor one moves around.

Getting started
|
|
---------------
|
|
|
|
Building
|
|
~~~~~~~~
|
|
|
|
Kakoune dependencies are:
|
|
|
|
* A C++11 compliant compiler (GCC >= 4.8 or clang >= 3.4)
|
|
* boost (>= 1.50)
|
|
* ncurses with wide-characters support (>= 5.3, generally refered as libncursesw)
|
|
|
|
To build, just type *make* in the src directory
|
|
|
|
Kakoune can be built on Linux, MacOS, and Cygwin. Due to Kakoune relying heavily
|
|
on being in an Unix like environment, no native Windows version is planned.
|
|
|
|
Installing
|
|
~~~~~~~~~~
|
|
|
|
In order to install kak on your system, rather than running it directly from
|
|
it's source directory, type *make install*, you can specify the `PREFIX` and
|
|
`DESTDIR` if needed.
|

Running
|
|
~~~~~~~
|
|
|
|
Just running *kak* launch a new kak session with a client on local terminal.
|
|
*kak* accepts some switches:
|
|
|
|
* `-c <session>`: connect to given session, sessions are unix sockets
|
|
`/tmp/kak-<session>`
|
|
* `-e <commands>`: execute commands on startup
|
|
* `-n`: ignore kakrc file
|
|
* `-s <session>`: set the session name, by default it will be the pid
|
|
of the initial kak process.
|
|
* `-d`: run Kakoune in daemon mode, without user interface. This requires
|
|
the session name to be specified with -s. In this mode, the Kakoune
|
|
server will keep running even if there is no connected client, and
|
|
will quit when receiving SIGTERM.
|
|
* `-p <session>`: read stdin, and then send its content to the given session
|
|
acting as a remote control.
|
|
* `-f <keys>`: Work as a filter, read every file given on the command line
|
|
and stdin if piped in, and apply given keys on each.
|
|
|
|
At startup, if `-n` is not specified, Kakoune will try to source the file
|
|
../share/kak/kakrc relative to the kak binary. This kak file will then try
|
|
to source any files in $XDG_CONFIG_HOME/kak/autoload (with $XDG_CONFIG_HOME
|
|
defaulting to $HOME/.config), and finally $XDG_CONFIG_HOME/kak/kakrc.
|
|
|
|
The common pattern is to add links to $XDG_CONFIG_HOME/kak/autoload to the
|
|
scripts in $PREFIX/share/kak/rc that the user wants sourced at kak launch.
|
|
|
|
Basic Interaction
|
|
-----------------
|
|
|
|
Selections
|
|
~~~~~~~~~~
|
|
|
|
The main concept in Kakoune is the selection. A selection is an inclusive,
|
|
directed range of character. A selection has two ends, the anchor and the
|
|
cursor.
|
|
|
|
There is always at least one selection, and a selection is always at least
|
|
one character (in which case the anchor and cursor of the selections are
|
|
on the same character).
|
|
|
|
Normal Mode
|
|
~~~~~~~~~~~
|
|
|
|
In normal mode, keys are not inserted directly inside the buffer, but are editing
|
|
commands. These commands provides ways to manipulate either the selections themselves,
|
|
or the selected text.
|
|
|
|
Insert Mode
|
|
~~~~~~~~~~~
|
|
|
|
When entering insert mode, keys are now directly inserted before each selections
|
|
cursor. A few additional keys are supported, like arrow keys to move around, however
|
|
their use is not encouraged. You can go back to normal mode by pressing the `<esc>`
|
|
key.
|
|
|
|
Movement
|
|
~~~~~~~~
|
|
|
|
* `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
|
|
* `alt-[wbe]`: same as [wbe] but select WORD instead of word
|
|
|
|
* `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)
|
|
* `alt-X`: trim selections to only contain full lines (not including last
|
|
end-of-line)
|
|
|
|
* `%`: select whole buffer
|
|
|
|
* `alt-H`: select to line begin
|
|
* `alt-L`: select to line end
|
|
|
|
* `/`: search (select next match)
|
|
* `?`: search (extend to next match)
|
|
* `n`: select next match
|
|
* `N`: add a new selection with next match
|
|
* `alt-n`: select previous match
|
|
* `alt-N`: add a new selection with previous match
|
|
|
|
* `pageup`: scroll up
|
|
* `pagedown`: scroll down
|
|
|
|
* `alt-r`: rotate selections (the main selection becomes the next one)
|
|
|
|
* `;`: reduce selections to their cursor
|
|
* `alt-;`: flip the selections direction
|
|
* `alt-:`: ensure selections are in forward direction (cursor after anchor)
|
|
|
|
|
|
A word is a sequence of alphanumeric characters or underscore, a WORD is a
|
|
sequence of non whitespace characters.
|
|
|
|
Appending
|
|
~~~~~~~~~
|
|
|
|
for most selection commands, using shift permits to extend 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.
|
|
|
|

push the previous selections to the client's jump list. It is possible
|
|
to forward or backward in the jump list using:
|
|
|
|
* `control-i`: Jump forward
|
|
* `control-o`: Jump backward
|
|
* `control-s`: save current selections
|
|
|
|
Multi Selection
|
|
~~~~~~~~~~~~~~~
|
|
|
|
Kak was designed from the start to handle multiple selections.
|
|
One 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 `S`, which splits the current
|
|
selection according to the regex entered. To split a comma separated list,
|
|
use `S` then ', *'
|
|
|
|
`s` and `S` share the search pattern with `/`, and hence entering an empty
|
|
pattern uses the last one.
|
|
|
|
As a convenience, `alt-s` allows you to split the current selections on
|
|
line boundaries.
|
|
|
|
To clear multiple selections, use `space`. To keep only the nth selection
|
|
use `n` followed by `space`, in order to remove a selection, use `alt-space`.
|
|
|
|
`alt-k` allows you to enter a regex and keep only the selections that
|
|
contains a match for this regex. using `alt-K` you can keep the selections
|
|
not containing a match.
|
|
|
|
`C` copies the current selection to the next line (or lines if a count is given)
|
|
`alt-C` does the same to previous lines.
|
|
|
|
`$` allows you to enter a shell command and pipe each selections to it.
|
|
Selections whose shell command returns 0 will be kept, other will be dropped.
|
|
|
|
Object Selection
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
Some keys allow you to select a text object:
|
|
|
|
* `alt-a`: selects the whole object
|
|
* `alt-i`: selects the inner object, that is the object excluding it's surrounder.
|
|
for example, for a quoted string, this will not select the quote, and
|
|
for a word this will not select trailing spaces.
|
|
* `[`: selects to object start
|
|
* `]`: selects to object end
|
|
* `{`: extends selections to object start
|
|
* `}`: extends selections to object end
|
|
|
|
After this key, you need to enter a second key in order to specify which
|
|
object you want.
|
|
|
|
* `b`, `(` or `)`: select the enclosing parenthesis
|
|
* `B`, `{` or `}`: select the enclosing {} block
|
|
* `r`, `[` or `]`: select the enclosing [] block
|
|
* `a`, `<` or `>`: select the enclosing <> block
|
|
* `"`: select the enclosing double quoted string
|
|
* `'`: select the enclosing single quoted string
|
|
* ```: select the enclosing grave quoted string
|
|
* `w`: select the whole word
|
|
* `W`: select the whole WORD
|
|
* `s`: select the sentence
|
|
* `p`: select the paragraph
|
|
* `␣`: select the whitespaces
|
|
* `i`: select the current indentation block
|
|
* `n`: select the number
|
|
|
|
For nestable objects, a count can be used in order to specify which surrounding
|
|
level to select.
|
|
|
|
Commands
|
|
--------
|
|
|
|
When pressing `:` in normal mode, Kakoune will open a prompt to enter a command.
|
|
|
|
Commands are used for non editing tasks, such as opening a buffer, writing the
|
|
current one, quitting, etc...
|
|
|
|
Basic Commands
|
|
~~~~~~~~~~~~~~
|
|
|
|
* `e[dit] <filename> [<line> [<column>]]`: open buffer on file, go to given
|
|
line and column. If file is already opened, just switch to this file.
|
|
use edit! to force reloading.
|
|
* `w[rite] [<filename>]`: write buffer to <filename> or use it's name if
|
|
filename is not given.
|
|
* `w[rite]a[ll]`: write all buffers that are associated to a file.
|
|
* `q[uit]`: exit Kakoune, use quit! to force quitting even if there is some
|
|
unsaved buffers remaining.
|
|
* `wq`: write current buffer and quit
|
|
* `b[uffer] <name>`: switch to buffer <name>
|
|
* `d[el]b[uf] [<name>]`: delete the buffer <name>, use d[el]b[uf]! to force
|
|
deleting a modified buffer.
|
|
* `source <filename>`: execute commands in <filename>
|
|
* `runtime <filename>`: execute commands in <filename>, <filename>
|
|
is relative to kak executable path.
|
|
* `nameclient <name>`: set current client name
|
|
* `namebuf <name>`: set current buffer name
|
|
* `echo <text>`: show <text> in status line
|
|
* `nop`: does nothing, but as with every other commands, arguments may be
|
|
evaluated. So nop can be used for example to execute a shell command
|
|
while being sure that it's output will not be interpreted by kak.
|
|
`:%sh{ echo echo tchou }` will echo tchou in Kakoune, whereas
|
|
`:nop %sh{ echo echo tchou }` will not, but both will execute the
|
|
shell command.
|
|
|
|
String syntax
|
|
~~~~~~~~~~~~~
|
|
|
|
When entering a command, parameters are separated by whitespace (shell like),
|
|
if you want to give parameters with spaces, you should quote them.
|
|
|
|
Kakoune support three string syntax:
|
|
|
|
* `'strings'`: uninterpreted strings, you can use `\'` to escape the separator,
|
|
every other char is itself.
|
|
|
|
* `"strings"`: expanded strings, % strings (see <<Expansions>>) contained
|
|
are expended. Use \% to escape a % inside them, and \\ to escape a slash.
|
|
|
|
* `%{strings}`: these strings are very useful when entering commands
|
|
|
|
- the `{` and `}` delimiter are configurable: you can use any non
|
|
alphanumeric character. like `%[string]`, `%<string>`, `%(string)`,
|
|
`%\~string~` or `%!string!`...
|
|
- if the character following the % is one of {[(<, then the closing one is
|
|
the matching }])> and the delimiters are not escapable but are nestable.
|
|
for example `%{ roger {}; }` is a valid string, `%{ marcel \}` as well.
|
|
|
|
Expansions
|
|
^^^^^^^^^^
|
|
|
|
A special kind of `%{strings}` can be used, with a type between
|
|
`%` and the opening delimiter (which cannot be alphanumeric). These
|
|
strings are expanded according to their type.
|
|
|
|
For example `%opt{autoinfo}` is of type 'opt'. opt expansions are replaced
|
|
by the value of the given option (here `autoinfo`).
|
|
|
|
Supported types are:
|
|
|
|
* `sh`: shell expansion, similar to posix shell $(...) construct, see
|
|
<<Shell expansion>> for more details.
|
|
* `reg`: register expansion, will be replaced by the content of the given
|
|
register.
|
|
* `opt`: option expansion, will be replaced with the value of the given
|
|
option
|
|
* `val`: value expansion, gives access to the environment variable available
|
|
to the Shell expansion. The `kak_` prefix is not used there.
|
|
|
|
for example you can display last search pattern with
|
|
|
|
-------------
|
|
:echo %reg{/}
|
|
-------------
|
|
|
|
Shell expansion
|
|
^^^^^^^^^^^^^^^
|
|
|
|
The `%sh{...}` expansion replaces it's content with the output of the shell
|
|
commands in it, it is similar to the shell $(...) syntax and is evaluated
|
|
only when needed.
|
|
|
|
for example: %sh{ ls } is replaced with the output of the ls command.
|
|
|
|
Some of Kakoune state is available through environment variables:
|
|
|
|
* `kak_selection`: content of the main selection
|
|
* `kak_selections`: content of the selection separated by colons, colons in
|
|
the selection contents are escapted with a backslash.
|
|
* `kak_bufname`: name of the current buffer
|
|
* `kak_buflist`: the current buffer list, each buffer seperated by a colon
|
|
* `kak_timestamp`: timestamp of the current buffer, the timestamp is an
|
|
integer value which is incremented each time the buffer is modified.
|
|
* `kak_runtime`: directory containing the kak binary
|
|
* `kak_opt_<name>`: value of option <name>
|
|
* `kak_reg_<r>`: value of register <r>
|
|
* `kak_socket`: filename of session socket (/tmp/kak-<session>)
|
|
* `kak_client`: name of current client
|
|
* `kak_cursor_line`: line of the end of the main selection
|
|
* `kak_cursor_column`: column of the end of the main selection (in byte)
|
|
* `kak_cursor_char_column`: column of the end of the main selection (in character)
|
|
* `kak_hook_param`: filtering text passed to the currently executing hook
|
|
|
|
Note that in order to make only needed information available, Kakoune needs
|
|
to find the environment variable reference in the shell script executed.
|
|
Hence `%sh{ ./script.sh }` with `script.sh` referencing an environment
|
|
variable will not work.
|
|
|
|
for example you can print informations on the current file in the status
|
|
line using:
|
|
|
|
-------------------------------
|
|
:echo %sh{ ls -l $kak_bufname }
|
|
-------------------------------
|
|
|
|
Kakrc
|
|
-----
|
|
|
|
If not launched with the `-n` switch, Kakoune will source the
|
|
`../share/kak/kakrc` file (relative to the `kak` binary), which
|
|
will in turn source additional files:
|
|
|
|
If the `$XDG_CONFIG_HOME/kak/autoload` directory exists, load every
|
|
`*.kak` files in it, and load recursively any subdirectory.
|
|
|
|
If it does not exists, falls back to the site wide autoload directory
|
|
in `../share/kak/autoload/`.
|
|
|
|
After that, if it exists, source the `$XDG_CONFIG_HOME/kak/kakrc` file
|
|
which should be used for user configuration.
|
|
|
|
In order to continue autoloading site-wide files with a local autoload
|
|
directory, just add a symbolic link to `../share/kak/autoload/` into
|
|
your local autoload directory.
|
|
|
|
Options
|
|
-------
|
|
|
|
For user configuration, Kakoune supports options.
|
|
|
|
Options are typed, their type can be
|
|
|
|
* `int`: an integer number
|
|
* `bool`: a boolean value, `yes/true` or `no/false`
|
|
* `yesnoask`: similar to a boolean, but the additional
|
|
value `ask` is supported.
|
|
* `str`: a string, some freeform text
|
|
* `coord`: a line,column pair (separated by comma)
|
|
* `regex`: as a string but the `set` commands will complain
|
|
if the entered text is not a valid regex.
|
|
* `{int,str}-list`: a list, elements are separated by a colon (:)
|
|
if an element needs to contain a colon, it can be escaped with a
|
|
backslash.
|
|
|
|
Options value can be changed using the `set` commands:
|
|
|
|
------------------------------------------------------------------------------
|
|
:set [global,buffer,window] <option> <value> # buffer, window, or global scope
|
|
------------------------------------------------------------------------------
|
|
|
|
Option values can be different by scope, an option can have a global
|
|
value, a buffer value and a window value. The effective value of an
|
|
option depends on the current context. If we have a window in the
|
|
context (interactive edition for example), then the window value
|
|
(if any) is used, if not we try the buffer value (if we have a buffer
|
|
in the context), and if not we use the global value.
|
|
|
|
That means that two windows on the same buffer can use different options
|
|
(like different filetype, or different tabstop). However some options
|
|
might end up ignored if their scope is not in the command context:
|
|
|
|
Writing a file never uses the window options for example, so any
|
|
options related to writing wont be taken into account if set in the
|
|
window scope (`BOM` or `eolformat` for example).
|
|
|
|
New options can be declared using the `:decl` command:
|
|
|
|
---------------------------------------
|
|
:decl [-hidden] <type> <name> [<value>]
|
|
---------------------------------------
|
|
|
|
the `-hidden` parameter makes the option invisible in completion, but
|
|
still modifiable.
|
|
|
|
Some options are built in Kakoune, and can be used to control it's behaviour:
|
|
|
|
* `tabstop` _int_: width of a tab character.
|
|
* `indentwidth` _int_: width (in spaces) used for indentation.
|
|
0 means a tab character.
|
|
* `scrolloff` _coord_: number of lines,columns to keep visible around
|
|
the cursor when scrolling.
|
|
* `eolformat` _string_ ('lf' or 'crlf'): the format of end of lines when
|
|
writing a buffer, this is autodetected on load.
|
|
* `BOM` _string_ ("no" or "utf-8"): define if the file should be written
|
|
with an unicode byte order mark.
|
|
* `complete_prefix` _bool_: when completing in command line, and multiple
|
|
candidates exist, enable completion with common prefix.
|
|
* `incsearch` _bool_: execute search as it is typed
|
|
* `aligntab` _bool_: use tabs for alignement command
|
|
* `autoinfo` _bool_: display automatic information box for certain commands.
|
|
* `autoshowcompl` _bool_: automatically display possible completions when
|
|
editing a prompt.
|
|
* `ignored_files` _regex_: filenames matching this regex wont be considered
|
|
as candidates on filename completion (except if the text being completed
|
|
already matches it).
|
|
* `disabled_hooks` _regex_: hooks whose group matches this regex wont be
|
|
executed. For example indentation hooks can be disabled with '.*-indent'.
|
|
* `filetype` _str_: arbitrary string defining the type of the file
|
|
filetype dependant actions should hook on this option changing for
|
|
activation/deactivation.
|
|
* `path` _str-list_: directories to search for gf command.
|
|
* `completers` _str-list_: completion systems to use for insert mode
|
|
completion. given completers are tried in order until one generate some
|
|
completion candidates. Existing completers are:
|
|
- `word=all` or `word=buffer` which complete using words in all buffers
|
|
(`word=all`) or only the current one (`word=buffer`)
|
|
- `filename` which tries to detect when a filename is being entered and
|
|
provides completion based on local filesystem.
|
|
- `option=<opt-name>` where <opt-name> is a _str-list_ option. The first
|
|
element of the list should follow the format:
|
|
_<line>.<column>[+<length>]@<timestamp>_ to define where the completion
|
|
apply in the buffer, and the other strings are the candidates.
|
|
* `autoreload` _yesnoask_: auto reload the buffers when an external
|
|
modification is detected.
|
|
* `ui_options`: colon separated list of key=value pairs that are forwarded to
|
|
the user interface implementation. The NCurses UI support the following option:
|
|
- `ncurses_status_on_top`: if `yes`, or `true` the status line will be placed
|
|
at the top of the terminal rather than at the bottom.
|
|
- `ncurses_assistant`: specify the nice assistant you get in info boxes, can
|
|
be 'clippy' (the default), 'cat' or 'none'
|
|
- `ncurses_wheel_down_button` and `ncurses_wheel_up_button`: specify which
|
|
button send for wheel down/up events.
|
|
|
|
Faces
|
|
-----
|
|
|
|
A Face refer the how specified text is displayed, a Face has a foreground
|
|
color, a background color, and some attributes.
|
|
|
|
Faces can be defined and modified with the face command.
|
|
|
|
-----------------------
|
|
:face <name> <facespec>
|
|
-----------------------
|
|
|
|
Any place requiring a face can take either a face name defined with the `face`
|
|
command or a direct face description (called _facespec_) with the following
|
|
syntax:
|
|
|
|
--------------------------------
|
|
fg_color[,bg_color][+attributes]
|
|
--------------------------------
|
|
|
|
fg_color and bg_color can be:
|
|
|
|
* A named color: `black, red, green, yellow, blue, magenta, cyan, white`.
|
|
* `default`, which keeps the existing color
|
|
* An rgb color: `rgb:RRGGBB`, with RRGGBB the hexadecimal value of the color.
|
|
|
|
not specifying bg_color uses `default`
|
|
|
|
attributes is a string of letters each defining an attributes:
|
|
|
|
* `u`: Underline
|
|
* `r`: Reverse
|
|
* `b`: Bold
|
|
|
|
Using named faces instead of facespec permits to change the effective faces
|
|
afterward.
|
|
|
|
there are some builtins faces used by internal Kakoune functionalities:
|
|
|
|
* `PrimarySelection`: main selection face for every selected character except
|
|
the cursor
|
|
* `SecondarySelection`: secondary selection face for every selected character
|
|
except the cursor
|
|
* `PrimaryCursor`: cursor of the primary selection
|
|
* `SecondaryCursor`: cursor of the secondary selection
|
|
* `LineNumbers`: face used by the number_lines highlighter
|
|
* `LineNumberAbsolute`: face used to highlight the line number of the main
|
|
selection
|
|
* `MenuForeground`: face for the selected element in menus
|
|
* `MenuBackground`: face for the not selected elements in menus
|
|
* `Information`: face for the informations windows and information messages
|
|
* `Error`: face of error messages
|
|
* `StatusLine`: face used for the status line
|
|
* `StatusCursor`: face used for the status line cursor
|
|
* `Prompt`: face used prompt displayed on the status line
|
|
|

Advanced topics

|
---------------
|
|
|
|
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
|
|
selections.
|
|
|
|
Yanking and pasting uses the register `"`, however most commands using register
|
|
can have their default register overriden by using the `"` key followed by the
|
|
register. For example `"sy` will yank (`y` command) in the `s` register. `"sp`
|
|
will paste from the `s` register.
|
|
|
|
While in insert mode or in a prompt, `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.
|
|
|
|
Macros
|
|
~~~~~~
|
|
|
|
Kakoune can record and replay a sequence of key press.
|
|
|
|
When pressing the `Q` key, followed by an alphabetic key for the macro name,
|
|
Kakoune begins macro recording: every pressed keys will be added to the
|
|
macro until the `Q` key is pressed again.
|
|
|
|
To replay a macro, use the `q` key, followed by the macro name.
|
|
|
|
macros are actually stored as a key sequence into a register, a macro name
|
|
is a register name.
|
|
|
|
Search selection
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
Using the `*` key, you can set the search pattern to the current selection.
|
|
This tries to be intelligent. It will for example detect if current selection
|
|
begins and/or end at word boundaries, and set the search pattern accordingly.
|
|
|
|
with `alt-*` you can set the search pattern to the current seletion without
|
|
Kakoune trying to be smart.
|
|
|
|
Exec and Eval
|
|
~~~~~~~~~~~~~
|
|
|
|
the `:exec` and `:eval` commands can be used for running Kakoune commands.
|
|
`:exec` run keys as if they were pressed, whereas `:eval` executes it's given
|
|
paremeters as if they were entered in the command prompt. By default,
|
|
they do their execution in the context of the current client.
|
|
|
|
Some parameters provide a way to change the context of execution:
|
|
|
|
* `-client <name>`: execute in the context of the client named <name>
|
|
* `-try-client <name>`: execute in the context of the client named
|
|
<name> if such client exists, or else in the current context.
|
|
* `-draft`: execute in a copy of the context of the selected client
|
|
modifications to the selections or input state will not affect
|
|
the client. This permits to make some modification to the buffer
|
|
without modifying the user's selection.
|
|
* `-itersel` (requires `-draft`): execute once per selection, in a
|
|
context with only the considered selection. This permits to avoid
|
|
cases where the selections may get merged.
|
|
* `-buffer <names>`: execute in the context of each buffers in the
|
|
comma separated list <names>, '*' as a name can be used to iterate
|
|
on all buffers.
|
|
* `-no-hooks`: disable hook execution while executing the keys/commands
|
|
|
|
The execution stops when the last key/command is reached, or an error
|
|
is raised.
|
|
|
|
key parameters gets concatenated, so the following commands are equivalent.
|
|
|
|
----------------------
|
|
:exec otest<space>1
|
|
:exec o test <space> 1
|
|
----------------------
|
|
|
|
Insert mode completion
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Kakoune can propose completions while inserting text, the `completers` option
|
|
control automatic completion, which kicks in when a certain idle timeout is
|
|
reached (100 milliseconds). Insert mode completion can be explicitely triggered
|
|
using *control-x*, followed, by:
|
|
|
|
* *f* : filename completion
|
|
* *w* : buffer word completion
|
|
* *l* : buffer line completion
|
|
* *o* : option based completion
|
|
|
|
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>
|
|
----------------------
|
|
|
|
`highlighter_id` is a name generated by the highlighter specified with `highlighter_name`,
|
|
possibly dependent on the parameters. Use command completion on rmhl to see the existing
|
|
highlighters id.
|
|
|
|
general highlighters are:
|
|
|
|
* `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 //(\h`TODO:)?[^\n]` 0:cyan 1:yellow,red`
|
|
will highlight C++ style comments in cyan, with an eventual 'TODO:' in
|
|
yellow on red background.
|
|
* `search`: highlight every matches to the current search pattern with the
|
|
`Search` face
|
|
* `flag_lines <flag> <option_name>`: add a column in front of text, and display the
|
|
given flag in it for everly lines 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 <-relative> <-hlcursor>`: show line numbers. The -relative switch
|
|
will show line numbers to main cursor line, the -hlcursor switch will
|
|
highlight the cursor line with a separate face..
|
|
* `fill <face>`: fill using given face, mostly useful with <<regions-highlighters,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>
|
|
------------------
|
|
|
|
and then the `-group` switch of `addhl` 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.
|
|
|
|
------------------------------------------------
|
|
addhl -group <name> group <subname>
|
|
addhl -group <name>/<subname> <type> <params>...
|
|
------------------------------------------------
|
|
|
|
[[regions-highlighters]]
|
|
Regions highlighters
|
|
^^^^^^^^^^^^^^^^^^^^
|
|
|
|
A special highlighter provide a way to segment the buffer into regions, which are
|
|
to be highlighted differently.
|
|
|
|
A region is defined by 4 parametes:
|
|
|
|
------------------------------------
|
|
<name> <opening> <closing> <recurse>
|
|
------------------------------------
|
|
|
|
`name` is user defined, `opening`, `closing` and `recurse` are regexes.
|
|
|
|
* `opening` defines the region start text
|
|
* `closing` defines the region end text
|
|
* `recurse` defines the text that matches recursively an end token into the region.
|
|
|
|
`recurse` is useful for regions that can be nested, for example the `%sh{ ... }`
|
|
construct in kakoune accept nested `{ ... }` so `%sh{ ... { ... } ... }` is valid.
|
|
this region can be defined with:
|
|
|
|
------------------------
|
|
shell_expand %sh\{ \} \{
|
|
------------------------
|
|
|
|
Regions are used in the `regions` highlighter which can take any number
|
|
of regions.
|
|
|
|
-----------------------------------------------------------------------
|
|
addhl regions <name> <region_name1> <opening1> <closing1> <recurse1> \
|
|
<region_name2> <opening2> <closing2> <recurse2>...
|
|
-----------------------------------------------------------------------
|
|
|
|
defines multiple regions in which other highlighters can be added
|
|
|
|
-------------------------------------
|
|
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 multi_region -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 `:addhl` 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.
|
|
|
|
Hooks
|
|
~~~~~
|
|
|
|
commands can be registred to be executed when certain events arise.
|
|
to register a hook, use the hook command.
|
|
|
|
-----------------------------------------------------------------------
|
|
:hook [-group <group>] <scope> <hook_name> <filtering_regex> <commands>
|
|
-----------------------------------------------------------------------
|
|
|
|
<scope> can be either global, buffer or window (or any of their prefixes),
|
|
the scope are hierarchical, meaning that a Window calling a hook will
|
|
execute it's own, the buffer ones and the global ones.
|
|
|
|
<command> is a string containing the commands to execute when the hook is
|
|
called.
|
|
|
|
for example, to automatically use line numbering with .cc files,
|
|
use the following command:
|
|
|
|
-----------------------------------------------------
|
|
:hook global WinCreate .*\.cc %{ addhl number_lines }
|
|
-----------------------------------------------------
|
|
|
|
if <group> is given, make this hook part of the named group. groups
|
|
are used for removing hooks with the `rmhooks` command
|
|
|
|
-----------------------
|
|
rmhooks <scope> <group>
|
|
-----------------------
|
|
|
|
will remove every hooks in <scope> that are part of the given group.
|
|
|
|
existing hooks are:
|
|
|
|
* `NormalIdle`: A certain duration has passed since last key was pressed in
|
|
normal mode.
|
|
* `NormalBegin`: Entering normal mode
|
|

|
* `InsertEnd`: Leaving insert mode
|
|
* `InsertKey`: A key is received in insert mode, the key is used for filtering
|
|

Key Mapping
|
|
~~~~~~~~~~~
|
|
|
|
You can redefine keys meaning using the map command
|
|
|
|
------------------------------------------------------
|
|
:map <scope> <mode> <key> <keys>
|
|
------------------------------------------------------
|
|
|
|
with `scope` being one of `global, buffer or window` (or any prefix),
|
|
mode being `insert, normal, prompt, menu or user` (or any prefix), `key` being
|
|
a single key name and `keys` a list of keys.
|
|
|
|
`user` mode allows for user mapping behind the `,` key. Keys will be executed in
|
|
normal mode.
|
|
|
|
Defining Commands
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
new commands can be defined using the `:def` command.
|
|
|
|
------------------------------
|
|
:def <command_name> <commands>
|
|
------------------------------
|
|
|
|
<commands> is a string containing the commands to execute
|
|
|
|
def can also takes some flags:
|
|
|
|
* `-env-params`: pass parameters given to commands in the environment as
|
|
kak_paramN with N the parameter number
|
|
* `-shell-params`: pass parameters given to commands as positional parameters
|
|
to any shell expansions used in the command.
|
|
* `-file-completion`: try file completion on any parameter passed
|
|
to this command
|
|
* `-shell-completion`: following string is a shell command which takes
|
|
parameters as positional params and output one
|
|
completion candidate per line.
|
|
* `-allow-override`: allow the new command to replace an exisiting one
|
|
with the same name.
|
|
* `-hidden`: do not show the command in command name completions
|
|
* `-docstring`: define the documentation string for the command
|
|
|
|
Using shell expansion permits to define complex commands or to access
|
|
Kakoune state:
|
|
|
|
------------------------------------------------------
|
|
:def print_selection %{ echo %sh{ ${kak_selection} } }
|
|
------------------------------------------------------
|
|
|
|
Some helper commands can be used to define composite commands:
|
|
|
|
* `:prompt <prompt> <register> <command>`: Prompt the user for a string, when
|
|
the user validates, store the result in given <register> and run <commmand>.
|
|
the -init <str> switch allows setting initial content.
|
|
* `:onkey <register> <command>`: Wait for next key from user, writes it into given
|
|
<register> and execute commands.
|
|
* `:menu <label1> <commands1> <label2> <commands2>...`: display a menu using
|
|
labels, the selected label's commands are executed.
|
|
`menu` can take a -auto-single argument, to automatically run commands
|
|
when only one choice is provided. and a -select-cmds argument, in which
|
|
case menu takes three argument per item, the last one being a command
|
|
to execute when the item is selected (but not validated).
|
|
* `:info <text>`: display text in an information box, at can take a -anchor
|
|
option, which accepts `left`, `right` and `cursor` as value, in order to
|
|
specify where the info box should be anchored relative to the main selection.
|
|
* `:try <commands> catch <on_error_commands>`: prevent an error in <commands>
|
|
from aborting the whole commands execution, execute <on_error_commands>
|
|
instead. If nothing is to be done on error, the catch part can be ommitted.
|
|
* `:reg <name> <content>`: set register <name> to <content>
|
|
|
|
Note that these commands are available in interactive command mode, but are
|
|
not that useful in this context.
|
|
|
|
Aliases
|
|
~~~~~~~
|
|
|
|
With `:alias` commands can be given additional names. aliases are scoped, so
|
|
that an alias can refer to one command for a buffer, and to another for another
|
|
buffer.
|
|
|
|
--------------------------------
|
|
:alias <scope> <alias> <command>
|
|
--------------------------------
|
|
|
|
with `<scope>` being `global`, `buffer` or `window`, will define `<alias>` as
|
|
an alias for `<command>`
|
|
|
|
-------------------------------------
|
|
:unalias <scope> <alias> [<expected>]
|
|
-------------------------------------
|
|
|
|
Will remove the given alias in the given scope. If `<expected>` is specified
|
|
the alias will only be removed if its current value is `<expected>`.
|
|
|
|
FIFO Buffer
|
|
~~~~~~~~~~~
|
|
|
|
the `:edit` command can take a -fifo parameter:
|
|
|
|
---------------------------------------------
|
|
:edit -fifo <filename> [-scroll] <buffername>
|
|
---------------------------------------------
|
|
|
|
in this case, a buffer named `<buffername>` is created which reads its content
|
|
from fifo `<filename>`. When the fifo is written to, the buffer is automatically
|
|
updated.
|
|
|
|
if the `-scroll` switch is specified, the initial cursor position will be made
|
|
such as the window displaying the buffer will scroll as new data is read.
|
|
|
|
This is very useful for running some commands asynchronously while displaying
|
|
their result in a buffer. See rc/make.kak and rc/grep.kak for examples.
|
|
|
|
When the buffer is deleted, the fifo will be closed, so any program writing
|
|
to it will receive SIGPIPE. This is usefull as it permits to stop the writing
|
|
program when the buffer is deleted.
|
|
|
|
Menus
|
|
~~~~~
|
|
|
|
When a menu is displayed, you can use `j`, `<ctrl-n>` or `<tab>` to select the next
|
|
entry, and `k`, `<ctrl-p>` or `<shift-tab>` to select the previous one.
|
|
|
|
Using the `/` key, you can enter some regex in order to restrict available choices
|
|
to the matching ones.
