Terminal emulator                                     *terminal* *terminal-emulator*

Nvim embeds a VT220/xterm terminal emulator based on libvterm. The terminal is
presented as a special 'buftype', asynchronously updated as data is received
from the connected program.

Terminal buffers behave like normal buffers, except:
- With 'modifiable', lines can be edited but not deleted.
- 'scrollback' controls how many lines are kept.
- Output is followed ("tailed") if cursor is on the last line.
- 'modified' is the default. You can set 'nomodified' to avoid a warning when
  closing the terminal buffer.
- 'bufhidden' defaults to "hide".

                                      Type |gO| to see the table of contents.

==============================================================================
Start                                                           *terminal-start*

There are several ways to create a terminal buffer:

- Run the |:terminal| command.
- Call |nvim_open_term()| or `jobstart(…, {'term': v:true})`.
- Edit a "term://" buffer. Examples: >vim
    :edit term://bash
    :vsplit term://top

<    Note: To open a "term://" buffer from an autocmd, the |autocmd-nested|
    modifier is required. >vim
        autocmd VimEnter * ++nested split term://sh
<    (This is only mentioned for reference; use |:terminal| instead.)

When the terminal starts, the buffer contents are updated and the buffer is
named in the form of `term://{cwd}//{pid}:{cmd}`. This naming scheme is used
by |:mksession| to restore a terminal buffer (by restarting the {cmd}).

The terminal environment is initialized as in |jobstart-env|.

==============================================================================
Input                                                           *terminal-input*

To send input, enter |Terminal-mode| with |i|, |I|, |a|, |A| or
|:startinsert|. In this mode all keys except <C-\> are sent to the underlying
program. If <C-\> is pressed, the next key is sent unless it is <C-N> or <C-O>.
Use <C-\><C-N> to return to normal mode. |CTRL-\_CTRL-N|
Use <C-\><C-O> to execute one normal mode command and then return to terminal
mode. *t_CTRL-\_CTRL-O*

Terminal-mode forces these local options:

- 'cursorlineopt' = number
- 'nocursorcolumn'
- 'scrolloff' = 0
- 'sidescrolloff' = 0

Terminal-mode has its own |:tnoremap| namespace for mappings, this can be used
to automate any terminal interaction.

To map <Esc> to exit terminal-mode: >vim
    :tnoremap <Esc> <C-\><C-n>

To simulate |i_CTRL-R| in terminal-mode: >vim
    :tnoremap <expr> <C-R> '<C-\><C-N>"'.nr2char(getchar()).'pi'

To use `ALT+{h,j,k,l}` to navigate windows from any mode: >vim
    :tnoremap <A-h> <C-\><C-N><C-w>h
    :tnoremap <A-j> <C-\><C-N><C-w>j
    :tnoremap <A-k> <C-\><C-N><C-w>k
    :tnoremap <A-l> <C-\><C-N><C-w>l
    :inoremap <A-h> <C-\><C-N><C-w>h
    :inoremap <A-j> <C-\><C-N><C-w>j
    :inoremap <A-k> <C-\><C-N><C-w>k
    :inoremap <A-l> <C-\><C-N><C-w>l
    :nnoremap <A-h> <C-w>h
    :nnoremap <A-j> <C-w>j
    :nnoremap <A-k> <C-w>k
    :nnoremap <A-l> <C-w>l

You can also create menus similar to terminal mode mappings, but you have to
use |:tlmenu| instead of |:tmenu|.

Mouse input has the following behavior:

- If the program has enabled mouse events, the corresponding events will be
  forwarded to the program.
- If mouse events are disabled (the default), terminal focus will be lost and
  the event will be processed as in a normal buffer.
- If another window is clicked, terminal focus will be lost and nvim will jump
  to the clicked window
- If the mouse wheel is used while the mouse is positioned in another window,
  the terminal won't lose focus and the hovered window will be scrolled.

==============================================================================
Configuration                                                  *terminal-config*

- Options: 'modified', 'scrollback'
- Events: |TermOpen|, |TermEnter|, |TermLeave|, |TermClose|
- Event groups: "nvim.terminal" |default-autocmds|
- Highlight groups: |hl-TermCursor|

Terminal sets local defaults for some options, which may differ from your
global configuration.

- 'list' is disabled
- 'wrap' is disabled
- 'number' is disabled
- 'relativenumber' is disabled
- 'signcolumn' is set to "no"
- 'foldcolumn' is set to "0"

You can change the defaults with a TermOpen autocommand: >vim
    :autocmd TermOpen * setlocal list

By default, "[Process exited]" is displayed when the terminal process ends. To
disable that, you can delete the "nvim.terminal" TermClose handler (this also
deletes other |default-autocmds| TermClose functionality): >vim
    :autocmd! nvim.terminal TermClose
<

TERMINAL COLORS ~

The `{g,b}:terminal_color_x` variables control the terminal color palette,
where `x` is the color index between 0 and 15 inclusive.  The variables are
read during |TermOpen|. The value must be a color name or hexadecimal string.
Example: >vim
    let g:terminal_color_4 = '#ff0000'
    let g:terminal_color_5 = 'green'
Only works for RGB UIs (see 'termguicolors'); for 256-color terminals the
color index is just forwarded.

Editor highlighting (|syntax-highlighting|, |highlight-groups|, etc.) has
higher precedence: it is applied after terminal colors are resolved.

------------------------------------------------------------------------------
EVENTS                                                        *terminal-events*

Applications running in a :terminal buffer can send requests, which Nvim
exposes via the |TermRequest| event.

OSC 7: change working directory                                *terminal-osc7*

Shells can emit the "OSC 7" sequence to announce when the current directory
(CWD) changed.

You can configure your shell init (e.g. ~/.bashrc) to emit OSC 7, or your
terminal may attempt to do it for you.

To configure bash to emit OSC 7: >bash
  function print_osc7() {
    printf '\033]7;file://%s\033\\' "$PWD"
  }
  PROMPT_COMMAND='print_osc7'

Having ensured that your shell emits OSC 7, you can now handle it in Nvim. The
following code will run :lcd whenever your shell CWD changes in a :terminal
buffer: >lua

  vim.api.nvim_create_autocmd({ 'TermRequest' }, {
    desc = 'Handles OSC 7 dir change requests',
    callback = function(ev)
      local val, n = string.gsub(ev.data.sequence, '\027]7;file://[^/]*', '')
      if n > 0 then
        -- OSC 7: dir-change
        local dir = val
        if vim.fn.isdirectory(dir) == 0 then
          vim.notify('invalid dir: '..dir)
          return
        end
        vim.b[ev.buf].osc7_dir = dir
        if vim.api.nvim_get_current_buf() == ev.buf then
          vim.cmd.lcd(dir)
        end
      end
    end
  })

To try it out, select the above code and source it with `:'<,'>lua`, then run
this command in a :terminal buffer: >

    printf "\033]7;file://./foo/bar\033\\"

OSC 52: write to system clipboard                             *terminal-osc52*

Applications in the :terminal buffer can write to the system clipboard by
emitting an OSC 52 sequence. Example: >

    printf '\033]52;;%s\033\\' "$(echo -n 'Hello world' | base64)"

Nvim uses the configured |clipboard| provider to write to the system
clipboard. Reading from the system clipboard with OSC 52 is not supported, as
this would allow any arbitrary program in the :terminal to read the user's
clipboard.

OSC 52 sequences sent from the :terminal buffer do not emit a |TermRequest|
event. The event is handled directly by Nvim and is not forwarded to plugins.

OSC 133: shell integration                    *terminal-osc133* *shell-prompt*

Shells can emit semantic escape sequences (OSC 133) to mark where each prompt
starts and ends. The start of a prompt is marked by sequence `OSC 133 ; A ST`,
and the end by `OSC 133 ; B ST`.

You can configure your shell init (e.g. ~/.bashrc) to emit OSC 133 sequences,
or your terminal may attempt to do it for you (assuming your shell config
doesn't interfere).

- powershell: https://learn.microsoft.com/en-us/windows/terminal/tutorials/shell-integration#powershell-pwshexe
- vscode: https://code.visualstudio.com/docs/terminal/shell-integration

To configure bash to mark the start of each prompt, set $PROMPT_COMMAND: >bash

    # Prompt start:
    PROMPT_COMMAND='printf "\033]133;A\007"'
<
                                                *terminal_]]* *terminal_[[*
The |]]| and |[[| motions jump to the next/previous prompts, if your shell
emits OSC 133 as described above.

                                                *shell-prompt-signs*
To annotate each terminal prompt with a sign, call |nvim_buf_set_extmark()|
from a |TermRequest| handler: >lua

    vim.api.nvim_create_autocmd('TermOpen', {
      command = 'setlocal signcolumn=auto',
    })
    local ns = vim.api.nvim_create_namespace('my.terminal.prompt')
    vim.api.nvim_create_autocmd('TermRequest', {
      callback = function(ev)
        if string.match(ev.data.sequence, '^\027]133;A') then
          local lnum = ev.data.cursor[1]
          vim.api.nvim_buf_set_extmark(ev.buf, ns, lnum - 1, 0, {
            sign_text = '▶',
            sign_hl_group = 'SpecialChar',
          })
        end
      end,
    })
<
==============================================================================
Status Variables                                             *terminal-status*

Terminal buffers maintain some buffer-local variables and options. The values
are initialized before TermOpen, so you can use them in a local 'statusline'.
Example: >vim
    :autocmd TermOpen * setlocal statusline=%{b:term_title}

- *b:term_title*  Terminal title (user-writable), typically displayed in the
  window title or tab title of a graphical terminal emulator. Terminal
  programs can set this by emitting an escape sequence.
- 'channel'  Terminal PTY |job-id|.  Can be used with |chansend()| to send
  input to the terminal.
- The |TermClose| event gives the terminal job exit code in the |v:event|
  "status" field. For example, this autocommand outputs the terminal's exit
  code to |:messages|: >vim
    autocmd TermClose * echom 'Terminal exited with status '..v:event.status

Use |jobwait()| to check if the terminal job has finished: >vim
    let running = jobwait([&channel], 0)[0] == -1
<
==============================================================================
:Termdebug plugin                         *terminal-debug* *terminal-debugger*
                                               *package-termdebug* *termdebug*

The Terminal debugging plugin can be used to debug a program with gdb and view
the source code in a Vim window.  Since this is completely contained inside
Vim this also works remotely over an ssh connection.

Starting ~
                                                        *termdebug-starting*
Load the plugin with this command: >vim
    packadd termdebug
When loading the plugin from the |vimrc| file, add the "!" attribute: >vim
    packadd! termdebug
<                                                       *:Termdebug*
To start debugging use `:Termdebug` or `:TermdebugCommand` followed by the
command name, for example: >vim
    :Termdebug vim

This opens two windows:

- gdb window: A terminal window in which "gdb vim" is executed.  Here you can
  directly interact with gdb.
- program window: A terminal window for the executed program.  When "run" is
  used in gdb the program I/O will happen in this window, so that it does not
  interfere with controlling gdb.

The current window is used to show the source code.  When gdb pauses the
source file location will be displayed, if possible.  A sign is used to
highlight the current position, using highlight group debugPC.

If the buffer in the current window is modified, another window will be opened
to display the current gdb position.

Focus the terminal of the executed program to interact with it.  This works
the same as any command running in a terminal window.

When the debugger ends, typically by typing "quit" in the gdb window, the two
opened windows are closed.

Only one debugger can be active at a time.
                                                        *:TermdebugCommand*
If you want to give specific commands to the command being debugged, you can
use the `:TermdebugCommand` command followed by the command name and
additional parameters. >vim
    :TermdebugCommand vim --clean -c ':set nu'

Both the `:Termdebug` and `:TermdebugCommand` support an optional "!" bang
argument to start the command right away, without pausing at the gdb window
(and cursor will be in the debugged window).  For example: >vim
    :TermdebugCommand! vim --clean

To attach gdb to an already running executable or use a core file, pass extra
arguments.  E.g.: >vim
    :Termdebug vim core
    :Termdebug vim 98343

If no argument is given, you'll end up in a gdb window, in which you need to
specify which command to run using e.g. the gdb `file` command.


Example session ~
                                                        *termdebug-example*
Start in the Vim "src" directory and build Vim: >
    % make
Start Vim: >
    % ./vim
Load the termdebug plugin and start debugging Vim: >vim
    :packadd termdebug
    :Termdebug vim
You should now have three windows:
- source:  where you started
- gdb:     you can type gdb commands here
- program: the executed program will use this window

Put focus on the gdb window and type: >
    break ex_help
    run
Vim will start running in the program window.  Put focus there and type: >vim
    :help gui
Gdb will run into the ex_help breakpoint.  The source window now shows the
ex_cmds.c file.  A red "1 " marker will appear in the signcolumn where the
breakpoint was set.  The line where the debugger stopped is highlighted.  You
can now step through the program.  You will see the highlighting move as the
debugger executes a line of source code.

Run |:Over| a few times until the for loop is highlighted.  Put the cursor on
the end of "eap->arg", then call ":Eval".  You will see this displayed: >
    "eap->arg": 0x555555e68855 "gui"
This way you can inspect the value of local variables.  You can also focus the
gdb window and use a "print" command, e.g.: >
    print *eap
If mouse pointer movements are working, Vim will also show a balloon when the
mouse rests on text that can be evaluated by gdb.
You can also use the "K" mapping that will either use Nvim floating windows
to show the results.

Now go back to the source window and put the cursor on the first line after
the for loop, then type: >
    :Break
You will see a "1" marker appear, this indicates the new breakpoint.  Now
run ":Cont" command and the code until the breakpoint will be executed.

You can type more advanced commands in the gdb window.  For example, type: >
    watch curbuf
Now run ":Cont" (or type "cont" in the gdb window). Execution
will now continue until the value of "curbuf" changes, which is in do_ecmd().
To remove this watchpoint again type in the gdb window: >
    delete 3

You can see the stack by typing in the gdb window: >
    where
Move through the stack frames, e.g. with: >
    frame 3
The source window will show the code, at the point where the call was made to
a deeper level.


Stepping through code ~
                                                        *termdebug-stepping*
Put focus on the gdb window to type commands there.  Some common ones are:
- CTRL-C:   interrupt the program
- next:     execute the current line and stop at the next line
- step:     execute the current line and stop at the next statement,
            entering functions
- until:    execute until past the current cursor line or past a specified
            position or the current stack frame returns
- finish:   execute until leaving the current function
- where:    show the stack
- frame N:  go to the Nth stack frame
- continue: continue execution

                                                *:Run* *:Arguments*
In the window showing the source code these commands can be used to control
gdb:
- `:Run` [args]        run the program with [args] or the previous arguments
- `:Arguments` {args}  set arguments for the next `:Run`

- *:Break* set a breakpoint at the cursor position
- :Break [{position}] [thread {nr}] [if {expr}]
  set a breakpoint at the specified position if {position} is omitted, use the
  current file and line thread {nr} limits the breakpoint to one thread if
  {expr} sets a conditional breakpoint.
  Examples: >
      :Break if argc == 1
      :Break 42 thread 3 if x > 10
      :Break main
<
- *:Tbreak* set a temporary breakpoint at the cursor position
- :Tbreak [{position}] [thread {nr}] [if {expr}]
  like `:Break`, but the breakpoint is deleted after it is hit once.
  Examples: >
      :Tbreak if argc == 1
      :Tbreak 42 thread 3 if x > 10
      :Tbreak main
<
- *:Clear* delete the breakpoint at the cursor position

- *:Step*       execute the gdb "step" command
- *:Over*       execute the gdb "next" command (`:Next` is a Vim command)
- *:Until*      execute the gdb "until" command
- *:Finish*     execute the gdb "finish" command
- *:Continue*   execute the gdb "continue" command
- *:Stop*       interrupt the program

If gdb stops at a source line and there is no window currently showing the
source code, a new window will be created for the source code.  This also
happens if the buffer in the source code window has been modified and can't be
abandoned.

Gdb gives each breakpoint a number.  In Vim the number shows up in the sign
column, with a red background.  You can use these gdb commands:
- info break    list breakpoints
- delete N      delete breakpoint N
You can also use the `:Clear` command if the cursor is in the line with the
breakpoint, or use the "Clear breakpoint" right-click menu entry.


Inspecting variables ~
                                        *termdebug-variables* *:Evaluate*
- `:Evaluate`        evaluate the expression under the cursor
- `K`                same (see |termdebug_map_K| to disable)
- `:Evaluate` {expr} evaluate {expr}
- `:'<,'>Evaluate`   evaluate the Visually selected text

This is similar to using "print" in the gdb window.
You can usually shorten `:Evaluate` to `:Ev`.
The result is displayed in a floating window.
You can move the cursor to this window by running `:Evaluate` (or `K`) again.


Navigating stack frames ~
                                *termdebug-frames* *:Frame* *:Up* *:Down*
- `:Frame` [frame]       select frame [frame], which is a frame number,
                       address, or function name (default: current frame)
- `:Up` [count]          go up [count] frames (default: 1; the frame that
                       called the current)
- `+`                    same (see |termdebug_map_plus| to disable)
- `:Down` [count]        go down [count] frames (default: 1; the frame called
                       by the current)
- `-`                    same (see |termdebug_map_minus| to disable)


Other commands ~
                                                        *termdebug-commands*
- *:Gdb*      jump to the gdb window
- *:Program*  jump to the window with the running program
- *:Source*   jump to the window with the source code, create it if there
            isn't one
- *:Asm*      jump to the window with the disassembly, create it if there
            isn't one
- *:Var*      jump to the window with the local and argument variables,
            create it if there isn't one.  This window updates whenever the
            program is stopped

Events ~
                                                        *termdebug-events*
Four autocommands can be used: >vim
    au User TermdebugStartPre  echomsg 'debugging starting'
    au User TermdebugStartPost echomsg 'debugging started'
    au User TermdebugStopPre   echomsg 'debugging stopping'
    au User TermdebugStopPost  echomsg 'debugging stopped'
<
- *TermdebugStartPre* Before starting debugging. Not triggered if the debugger
  is already running or the debugger command cannot be executed.
- *TermdebugStartPost* After debugging has initialized.
  If a "!" bang is passed to `:Termdebug` or `:TermdebugCommand` the event is
  triggered before running the provided command in gdb.
- *TermdebugStopPre* Before debugging ends, when gdb is terminated, most likely
  after issuing a "quit" command in the gdb window.
- *TermdebugStopPost* After debugging has ended, gdb-related windows are closed,
  debug buffers wiped out and the state before the debugging was restored.


Customizing ~
                                *termdebug-customizing* *g:termdebug_config*
In the past several global variables were used for configuration.  These are
deprecated and using the g:termdebug_config dictionary is preferred.  When
g:termdebug_config exists the other global variables will NOT be used.
The recommended way is to start with an empty dictionary: >vim
    let g:termdebug_config = {}

Then you can add entries to the dictionary as mentioned below.  The
deprecated global variable names are mentioned for completeness.  If you are
switching over to using g:termdebug_config you can find the old variable name
and take over the value, then delete the deprecated variable.


Prompt mode ~
                                                *termdebug-prompt*
When on MS-Windows, gdb will run in a buffer with 'buftype' set to "prompt".
This works slightly differently:
- The gdb window will be in Insert mode while typing commands.  Go to Normal
  mode with <Esc>, then you can move around in the buffer, copy/paste, etc.
  Go back to editing the gdb command with any command that starts Insert mode,
  such as `a` or `i`.
- A separate :terminal window will be opened to run the debugged program in.

                                                *termdebug_use_prompt*
Prompt mode can be used with: >vim
    let g:termdebug_config['use_prompt'] = 1
If there is no g:termdebug_config you can use: >vim
    let g:termdebug_use_prompt = 1
<
Mappings ~
The termdebug plugin enables a few default mappings.  All those mappings
are reset to their original values once the termdebug session concludes.

                                        *termdebug_map_K* *termdebug-mappings*
The K key is normally mapped to |:Evaluate| unless a buffer local (|:map-local|)
mapping to K already exists.  If you do not want this use: >vim
    let g:termdebug_config['map_K'] = 0
If there is no g:termdebug_config you can use: >vim
    let g:termdebug_map_K = 0
<
                                                *termdebug_map_minus*
The - key is normally mapped to |:Down| unless a buffer local mapping to the -
key already exists.  If you do not want this use: >vim
    let g:termdebug_config['map_minus'] = 0
<
                                                *termdebug_map_plus*
The + key is normally mapped to |:Up| unless a buffer local mapping to the +
key already exists.  If you do not want this use: >vim
    let g:termdebug_config['map_plus'] = 0
<
                                                *termdebug_disasm_window*
If you want the Asm window shown by default, set the "disasm_window" flag to
1.  The "disasm_window_height" entry can be used to set the window height: >vim
    let g:termdebug_config['disasm_window'] = 1
    let g:termdebug_config['disasm_window_height'] = 15
If there is no g:termdebug_config you can use: >vim
    let g:termdebug_disasm_window = 15
Any value greater than 1 will set the Asm window height to that value.
If the current window has enough horizontal space, it will be vertically split
and the Asm window will be shown side by side with the source code window (and
the height option won't be used).

                                                *termdebug_variables_window*
If you want the Var window shown by default, set the "variables_window" flag
to 1.  The "variables_window_height" entry can be used to set the window
height: >vim
    let g:termdebug_config['variables_window'] = 1
    let g:termdebug_config['variables_window_height'] = 15
If there is no g:termdebug_config you can use: >vim
    let g:termdebug_variables_window = 15
Any value greater than 1 will set the Var window height to that value.
If the current window has enough horizontal space, it will be vertically split
and the Var window will be shown side by side with the source code window (and
the height options won't be used).


Communication ~
                                                *termdebug-communication*
There is another, hidden, buffer, which is used for Vim to communicate with
gdb.  The buffer name is "gdb communication".  Do not delete this buffer, it
will break the debugger.

Gdb has some weird behavior, the plugin does its best to work around that.
For example, after typing "continue" in the gdb window a CTRL-C can be used to
interrupt the running program.  But after using the MI command
"-exec-continue"  pressing CTRL-C does not interrupt.  Therefore you will see
"continue" being used for the `:Continue` command, instead of using the
communication channel.


GDB command ~
                                                        *g:termdebugger*
To change the name of the gdb command, set "debugger" entry in
g:termdebug_config or the "g:termdebugger" variable before invoking
`:Termdebug`: >vim
    let g:termdebug_config['command'] = "mygdb"
If there is no g:termdebug_config you can use: >vim
    let g:termdebugger = "mygdb"

If the command needs an argument use a List: >vim
    let g:termdebug_config['command'] = ['rr', 'replay', '--']
If there is no g:termdebug_config you can use: >vim
    let g:termdebugger = ['rr', 'replay', '--']

If you are a mouse person, you can also define a mapping using your right
click to one of the terminal command like evaluate the variable under the
cursor: >vim
    nnoremap <RightMouse> :Evaluate<CR>
or set/unset a breakpoint: >vim
    nnoremap <RightMouse> :Break<CR>


Several arguments will be added to make gdb work well for the debugger.
If you want to modify them, add a function to filter the argument list: >vim
    let g:termdebug_config['command_filter'] = MyDebugFilter

If you do not want the arguments to be added, but you do need to set the
"pty", use a function to add the necessary arguments: >vim
    let g:termdebug_config['command_add_args'] = MyAddArguments
The function will be called with the list of arguments so far, and a second
argument that is the name of the pty.
                                                        *gdb-version*
Only debuggers fully compatible with gdb will work.  Vim uses the GDB/MI
interface.  The "new-ui" command requires gdb version 7.12 or later.  If you
get this error: >
    Undefined command: "new-ui". Try "help".
Then your gdb is too old.


Colors ~
                                        *hl-debugPC* *hl-debugBreakpoint*
The color of the signs can be adjusted with these highlight groups:
- debugPC               the current position
- debugBreakpoint       a breakpoint

The defaults are, when 'background' is "light": >vim
  hi debugPC term=reverse ctermbg=lightblue guibg=lightblue
  hi debugBreakpoint term=reverse ctermbg=red guibg=red
<
When 'background' is "dark": >vim
  hi debugPC term=reverse ctermbg=darkblue guibg=darkblue
  hi debugBreakpoint term=reverse ctermbg=red guibg=red
<

Shortcuts ~
                                                        *termdebug_shortcuts*
You can define your own shortcuts (mappings) to control gdb, that can work in
any window, using the TermDebugSendCommand() function.  Example: >vim
    map ,w :call TermDebugSendCommand('where')<CR>
The argument is the gdb command.


Popup menu ~
                                                        *termdebug_popup*
By default the Termdebug plugin sets 'mousemodel' to "popup_setpos" and adds
these entries to the popup menu:
- Set breakpoint          `:Break`
- Clear breakpoint        `:Clear`
- Evaluate                `:Evaluate`
If you don't want this then disable it with: >vim
    let g:termdebug_config['popup'] = 0
If there is no g:termdebug_config you can use: >vim
    let g:termdebug_popup = 0
<

Change default signs ~
                                                        *termdebug_signs*
Termdebug uses the hex number of the breakpoint ID in the signcolumn to
represent breakpoints.  If it is greater than "0xFF", then it will be
displayed as "F+", because there are only two screen cells available for the
sign.  You may also use decimal breakpoint signs instead, in which case IDs
greater than 99 will be displayed as "9+".

If you want to customize the breakpoint signs to show `>>` in the signcolumn: >vim
    let g:termdebug_config['sign'] = '>>'
You can also specify individual signs for the first several breakpoints: >vim
    let g:termdebug_config['signs'] = ['>1', '>2', '>3', '>4', '>5', '>6', '>7', '>8', '>9']
    let g:termdebug_config['sign'] = '>>'
If you would like to use decimal (base 10) breakpoint signs: >vim
    let g:termdebug_config['sign_decimal'] = 1
If the variable g:termdebug_config does not yet exist, you can use: >vim
    let g:termdebug_config = {'sign': '>>'}
Likewise, to enable decimal signs: >vim
    let g:termdebug_config = {'sign_decimal': 1}


Vim window width ~
                                                        *termdebug_wide*
To change the width of the Vim window when debugging starts and use a vertical
split: >vim
    let g:termdebug_config['wide'] = 163
If there is no g:termdebug_config you can use: >vim
    let g:termdebug_wide = 163

This will set 'columns' to 163 when `:Termdebug` is used.  The value is
restored when quitting the debugger.

If the wide value is set and 'columns' is already a greater value, then a
vertical split will be used without modifying 'columns'.

Set the wide value to 1 to use a vertical split without ever changing
'columns'.  This is useful when the terminal can't be resized by Vim.
