See the link:doc/design.asciidoc[design document] for more information on Kakoune philosophy and design. :numbered: Introduction ------------ Kakoune is a code editor heavily inspired by Vim, as such most of its commands are similar to vi's ones, and it shares Vi's "keystrokes as a text editing language" model. 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. See http://vimeo.com/82711574 Join us on freenode IRC `#Kakoune` Features ~~~~~~~~ * Multiple selections as a central way of interacting * Powerful selection manipulation primitives - Select all regex matches in current selections - Keep selections containing/not containing a match for a given regex - Split current selections with a regex - Text objects (paragraph, sentence, nestable blocks) * Powerful text manipulation primitives - Align selections - Rotate selection contents - Case manipulation - Indentation - Piping each selection to external filter * Client-Server architecture - Multiple clients on the same editing session - Use tmux or your X11 window manager to manage windows * Simple interaction with external programs * Automatic contextual help * Automatic as you type completion * Macros * Hooks * Syntax Highlighting - Supports multiple languages in the same buffer - Highlight a buffer differently in different windows Screenshots ~~~~~~~~~~~ [[screenshot-i3]] .Kakoune in i3 image::doc/screenshot-i3.gif[Kakoune in i3] [[screenshot-tmux]] .Kakoune in tmux image::doc/screenshot-tmux.gif[Kakoune in tmux] Getting started --------------- Building ~~~~~~~~ Kakoune dependencies are: * A {cpp}11 compliant compiler (GCC >= 5 or clang >= 3.4) along with its associated {cpp} standard library (libstdc{pp} or libc{pp}) * boost (>= 1.50) * ncurses with wide-characters support (>= 5.3, generally referred to as libncursesw) * asciidoc (for the `a2k` tool), to generate man pages To build, just type *make* in the src directory. To generate man pages, type *make doc* in the src directory. Kakoune can be built on Linux, MacOS, and Cygwin. Due to Kakoune relying heavily on being in a Unix-like environment, no native Windows version is planned. Installing ~~~~~~~~~~ In order to install kak on your system, rather than running it directly from its source directory, type *make install*, you can specify the `PREFIX` and `DESTDIR` if needed. [TIP] .Homebrew (OSX) ==== NOTE: The ncurses library that comes with OSX is not new enough to support some mouse based features of Kakoune (only tested on OSX 10.11.3, where the packaged ncurses library is version 5.4, whereas the latest version is 6.0). Currently, a fresh Kakoune install requires that you install ncurses 6.0. You can install ncurses 6.0 via Homebrew, ----------------------------------- brew install homebrew/dupes/ncurses ----------------------------------- Then, to install, --------------------------------------------------------------------------------------------- brew install --HEAD https://raw.githubusercontent.com/mawww/kakoune/master/contrib/kakoune.rb --------------------------------------------------------------------------------------------- To update kakoune, --------------------------------- brew upgrade --fetch-HEAD kakoune --------------------------------- ==== [TIP] .Fedora 22/23/24/Rawhide ==== Use the https://copr.fedoraproject.org/coprs/jkonecny/kakoune/[copr] repository. --------------------------------- dnf copr enable jkonecny/kakoune dnf install kakoune --------------------------------- ==== [TIP] .Arch Linux ==== A PKGBUILD https://aur.archlinux.org/packages/kakoune-git[kakoune-git] to install Kakoune is available in the https://wiki.archlinux.org/index.php/Arch_User_Repository[AUR]. -------------------------------------------------- # For example build and install Kakoune via yaourt yaourt -Sy kakoune-git -------------------------------------------------- ==== [TIP] .Gentoo ==== Kakoune is found in portage as https://packages.gentoo.org/packages/app-editors/kakoune[app-editors/kakoune] ==== [TIP] .Exherbo ==== -------------------------------- cave resolve -x repository/mawww cave resolve -x kakoune -------------------------------- ==== [TIP] .openSUSE ==== kakoune can be found in the https://build.opensuse.org/package/show/editors/kakoune[editors] devel project.

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 `: read stdin, and then send its content to the given session acting as a remote control. * `-f `: Work as a filter, read every file given on the command line and stdin if piped in, and apply given keys on each. * `-ui `: use given user interface, `` can be - `ncurses`: default terminal user interface - `dummy`: empty user interface not displaying anything - `json`: json-rpc based user interface that writes json on stdout and read keystrokes as json on stdin. * `-l`: list existing sessions, and check the dead ones * `-clear`: clear dead session's socket files * `-ro`: prevent modifications to all buffers from being saved to disk * `+line[:column]`: specify a target line and column for the first file Configuration ^^^^^^^^^^^^^ There are two directories containing Kakoune's scripts: * `runtime`: located in `../share/kak/` relative to the `kak` binary contains the system scripts, installed with Kakoune. * `userconf`: located in `$XDG_CONFIG_HOME/kak/`, which defaults to `$HOME/.config/kak/` on most systems, containing the user configuration. Unless `-n` is specified, Kakoune will load its startup script located at `${runtime}/kakrc` relative to the `kak` binary. This startup script is responsible for loading the user configuration. First, Kakoune will search recursively for `.kak` files in the `autoload` directory. It will first look for an `autoload` directory at `${userconf}/autoload` and will fallback to `${runtime}/autoload` if it does not exist. Once all those files are loaded, Kakoune will try to source `${runtime}/kakrc.local` which is expected to contain distribution provided configuration. And finally, the user configuration will be loaded from `${userconf}/kakrc`. NOTE: If you create a user `autoload` directory in `${userconf}/autoload`, the system one at `${runtime}/autoload` will not be loaded anymore. You can add a symbolic link to it (or to individual scripts) inside `${userconf}/autoload` to keep loading system scripts. 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 provide ways to manipulate either the selections themselves, or the selected text. Insert Mode ~~~~~~~~~~~ When entering insert mode, keys are now directly inserted before each selection's cursor. Some additional keys are recognised in insert mode: * ``: leave insert mode * ``: delete characters before cursors * ``: delete characters under cursors * `, , , `: move the cursors in given direction * ``: move cursors to line begin * ``: move cursors to end of line * ``: select next completion candidate * ``: select previous completion candidate * ``: explicit insert completion query, followed by: - `f`: explicit file completion - `w`: explicit word completion - `l`: explicit line completion * ``: disable automatic completion for this insert session * ``: insert contents of the register given by next key * ``: insert next keystroke directly into the buffer, without interpreting it. * ``: commit changes up to now as a single undo group. * ``: escape to normal mode for a single command Movement ~~~~~~~~ * `h`: select the character on the left 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 right 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 * ``: same as [wbe] but select WORD instead of word * `f`: select to the next occurence of given character * `t`: select until the next occurence of given character * ``: same as [ft] but in the other direction * `m`: select to matching character * `M`: extend selection to matching character * `x`: select line on which selection end lies (or next line when end lies on an end-of-line) * `X`: similar to `x`, except the current selection is extended * ``: expand selections to contain full lines (including end-of-lines) * ``: trim selections to only contain full lines (not including last end-of-line) * `%`: select whole buffer * ``: select to line begin * ``: select to line end * `/`: search (select next match) * ``: search (select previous match) * `?`: search (extend to next match) * ``: search (extend to previous match) * `n`: select next match * `N`: add a new selection with next match * ``: select previous match * ``: add a new selection with previous match * `pageup`: scroll up * `pagedown`: scroll down * `'`: rotate selections (the main selection becomes the next one) * ``: rotate selections backwards * `;`: reduce selections to their cursor * ``: flip the selections' direction * ``: ensure selections are in forward direction (cursor after anchor) * ``: repeat last object or `f`/`t` selection command. 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 extending 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. Disabling Hooks ~~~~~~~~~~~~~~~ Any normal mode command can be prefixed with `\` which will disable hook execution for the duration for the command (including the duration of modes the command could move to, so `\i` will disable hooks for the whole insert session). As autoindentation is implemented in terms of hooks, this can be used to disable it when pasting text. Changes ~~~~~~~ * `i`: enter insert mode before current selection * `a`: enter insert mode after current selection * `d`: yank and delete current selection * `c`: yank and delete current selection and enter insert mode * `.`: repeat last insert mode change (`i`, `a`, or `c`, including the inserted text) * `I`: enter insert mode at current selection begin line start * `A`: enter insert mode at current selection end line end * `o`: enter insert mode in one (or given count) new lines below current selection end * `O`: enter insert mode in one (or given count) new lines above current selection begin * `y`: yank selections * `p`: paste after current selection end * `P`: paste before current selection begin * ``: paste all after current selection end, and select each pasted string. * ``: paste all before current selection begin, and select each pasted string. * `R`: replace current selection with yanked text * `r`: replace each character with the next entered one * ``: join selected lines * ``: join selected lines and select spaces inserted in place of line breaks * ``: merge contiguous selections together (works across lines as well) * ` (>)`: indent selected lines * ``: indent selected lines, including empty lines * ` (<)`: deindent selected lines * ``: deindent selected lines, do not remove incomplete indent (3 leading spaces when indent is 4) * `|`: pipe each selection through the given external filter program and replace the selection with it's output. * ``: pipe each selection through the given external filter program and ignore its output * `!`: insert command output before selection * `a-!`: append command output after selection * `u`: undo last change * `a-u`: move backward in history * `U`: redo last change * `a-U`: move forward in history * `&`: align selection, align the cursor of selections by inserting spaces before the first character of the selection * ``: copy indent, copy the indentation of the main selection (or the count one if a count is given) to all other ones * ```: to lower case * `~`: to upper case * ``: swap case * `@`: convert tabs to spaces in current selections, uses the buffer tabstop option or the count parameter for tabstop. * ``: convert spaces to tabs in current selections, uses the buffer tabstop option or the count parameter for tabstop. * ``: rotate selections content, if specified, the count groups selections, so `3` rotate (1, 2, 3) and (3, 4, 6) independently. Goto Commands ~~~~~~~~~~~~~ Commands beginning with g are used to goto certain position and or buffer: * `gh`: select to line begin * `gl`: select to line end * `gi`: select to line begin (non blank) * `gg`, `gk`: go to the first line * `gj`: go to the last line * `ge`: go to last char of last line * `gt`: go to the first displayed line * `gc`: go to the middle displayed line * `gb`: go to the last displayed line * `ga`: go to the previous (alternate) buffer * `gf`: open the file whose name is selected * `g.`: go to last buffer modification position If a count is given prior to hitting `g`, `g` will jump to the given line. Using `G` will extend the selection rather than jump. View commands ~~~~~~~~~~~~~ Some commands, all beginning with v permit to manipulate the current view. * `vv` or `vc`: center the main selection in the window * `vt`: scroll to put the main selection on the top line of the window * `vb`: scroll to put the main selection on the bottom line of the window * `vh`: scroll the window count columns left * `vj`: scroll the window count line downward * `vk`: scroll the window count line upward * `vl`: scroll the window count columns right Using `V` will lock view mode until `` is hit Marks ~~~~~ Current selections position can be saved in a register and restored later on. By default, marks use the '^' register, but using the register can be set using `"` prefix. `Z` will save the current selections to the register. `` will append the current selections to the register. `z` will restore the selections from the register. `` will add the selections from the register to the existing ones. Jump list ~~~~~~~~~ Some commands, like the goto commands, buffer switch or search commands, push the previous selections to the client's jump list. It is possible to forward or backward in the jump list using: * ``: Jump forward * ``: Jump backward * ``: 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 occurrences 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 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 ', *' The regex syntax supported by Kakoune is the Perl one and is described here <>. `s` and `S` share the search pattern with `/`, and hence entering an empty pattern uses the last one. As a convenience, `` 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 ``. `` allows you to enter a regex and keep only the selections that contains a match for this regex. Using `` 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) `` does the same to previous lines. `$` allows you to enter a shell command and pipe each selection 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: * ``: selects the whole object * ``: selects the inner object, that is the object excluding its 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 * `"` or `Q`: select the enclosing double quoted string * `'` or `q`: select the enclosing single quoted string * ``` or `g`: 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 * `u`: select the argument * `:`: select user defined object, will prompt for open and close text. 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. A few keys are recognized by prompt mode to help edit a command: * ``: validate prompt * ``: abandon without * ` or `: move cursor to previous character * ` or `: move cursor to previous character * ``: move cursor to first character * ``: move cursor past the last character * ` or `: erase character before cursor * ` or `: erase character under cursor * ``: advance to next word begin * ``: advance to next WORD begin * ``: go back to previous word begin * ``: go back to previous WORD begin * ``: advance to next word end * ``: advance to next word end * ` or `: select previous entry in history * ` or `: select next entry in history * ``: select next completion candidate * ``: select previous completion candidate * ``: insert then content of the register given by next key. * ``: insert next keystroke without interpreting it * ``: disable auto completion for this prompt Commands starting with horizontal whitespace (e.g. a space) will not be saved in the command history. Basic Commands ~~~~~~~~~~~~~~ Some commands take an exclamation mark (`!`), which can be used to force the execution of the command (i.e. to quit a modified buffer, the command `q!` has to be used). * `cd []`: change the current directory to ``, or the home directory is unspecified * `doc `: display documentation about a topic. The completion list displays the available topics. * `e[dit][!] [ []]`: 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][!] []`: write buffer to or use its name if filename is not given. If the file is write-protected, its permissions are temporarily changed to allow saving the buffer and restored afterwards when the write! command is used. * `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. * `kill[!]`: terminate the current session, all the clients as well as the server, use kill! to ignore unsaved buffers * `w[a]q[!]`: write the current buffer (or all buffers when `waq` is used) and quit * `b[uffer] `: switch to buffer * `b[uffer]n[ext]`: switch to the next buffer * `b[uffer]p[rev]`: switch to the previous buffer * `d[el]b[uf][!] []`: delete the buffer * `source `: execute commands in * `colorscheme `: load named colorscheme. * `rename-client `: set current client name * `rename-buffer `: set current buffer name * `rename-session `: set current session name * `echo [options] `: show in status line, with the following options: ** `-color` : print the given text with , most commonly `Error` or `Information` ** `-markup`: expand the markup strings in ** `-debug`: print the given text to the `\*debug*` buffer * `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. Multiple commands ~~~~~~~~~~~~~~~~~ Multiple commands can be separated either by new lines or by semicolons, as such a semicolon must be escaped with `\;` to be considered as a literal semicolon argument. 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 <>) 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 `}` delimiters are configurable: you can use any non alphanumeric character, e.g. `%[string]`, `%`, `%(string)`, `%\~string~`, `%!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 <> 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. * `arg`: argument expansion, gives access to the arguments of the current command, the content can be a number, or `@` for all arguments. For example, you can display last search pattern with ------------- :echo %reg{/} ------------- Shell expansion ^^^^^^^^^^^^^^^ The `%sh{...}` expansion replaces its 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 and backslashes in the selection contents are escaped with a backslash. * `kak_selection_desc`: range of the main selection, represented as `anchor,cursor`; anchor and cursor are in this format: `line.column` * `kak_selections_desc`: range of the selecations separated by colons * `kak_bufname`: name of the current buffer * `kak_buffile`: full path of the file or same as `kak_bufname` when there's no associated file * `kak_buflist`: the current buffer list, each buffer separated 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_count`: count parameter passed to the command * `kak_opt_`: value of option * `kak_reg_`: value of register * `kak_session`: name of the current session * `kak_client`: name of current client * `kak_source`: path of the file currently getting executed (through the source command) * `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_cursor_byte_offset`: offset of the main selection from the beginning of the buffer (in byte). * `kak_window_width`: width of the current kakoune window * `kak_window_height`: height of the current kakoune window * `kak_hook_param`: filtering text passed to the currently executing hook * `kak_hook_param_capture_N`: text captured by the hook filter regex capture N * `kak_client_env_`: value of the variable in the client environment. Example: $kak_client_env_SHELL is the SHELL variable 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 $kak_bufname } ------------------------------- Markup strings ^^^^^^^^^^^^^^ In certain context, kakoune can take a markup string, which is a string containing formatting informations. In these strings, syntax `{facename}` will enable the face _facename_ until another face gets activated (or the end of the string. Literal `{` shall be written `\{`, and literal `\` that precede a `{` shall be written `\\` Configuration & Autoloading --------------------------- Kakrc ~~~~~ If not launched with the `-n` switch, Kakoune will source the `../share/kak/kakrc` file relative to the `kak` binary, which will source additional files: If the `$XDG_CONFIG_HOME/kak/autoload` directory exists, load every `*.kak` files in it, and load recursively any subdirectory. If it does not exist, falls back to the site wide autoload directory in `../share/kak/autoload/`. After that, if it exists, source the `$XDG_CONFIG_HOME/kak/kakrc` file which should be used for user configuration. In order to continue autoloading site-wide files with a local autoload directory, just add a symbolic link to `../share/kak/autoload/` into your local autoload directory. Color Schemes ~~~~~~~~~~~~~ Kakoune ships with some color schemes that are installed to `../share/kak/colors/`. If `$XDG_CONFIG_HOME/kak/colors/` is present the builtin command `colorscheme` will offer completion for those color schemes. If a scheme is duplicated in userspace, it will take precedence. 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` * `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. * `range-faces`: a `:` separated list of a pair of a buffer range (`.,.` or `.+`) and a face (separated by `|`), except for the first element which is just the timestamp of the buffer. * `line-flags`: a `:` separated list of a line number and a corresponding flag (`|`), except for the first element which is just the timestamp of the buffer. * `completions`: a `:` separated list of `||` candidates, except for the first element which follows the `.[+]@` format to define where the completion apply in the buffer. Markup can be used in the menu text. * `enum(value1|value2|...)`: an enum, taking on of the given values * `flags(value1|value2|...)`: a set of flags, taking a combination of the given values joined by `|`. Options value can be changed using the `set` commands: ------------------------------------------------------------------------------ :set [global,buffer,window]
