+2. Terminal functions *terminal-function-details*
+
+ *term_dumpdiff()*
+term_dumpdiff({filename}, {filename} [, {options}])
+ Open a new window displaying the difference between the two
+ files. The files must have been created with
+ |term_dumpwrite()|.
+ Returns the buffer number or zero when the diff fails.
+ Also see |terminal-diff|.
+ NOTE: this does not work with double-width characters yet.
+
+ The top part of the buffer contains the contents of the first
+ file, the bottom part of the buffer contains the contents of
+ the second file. The middle part shows the differences.
+ The parts are separated by a line of equals.
+
+ If the {options} argument is present, it must be a Dict with
+ these possible members:
+ "term_name" name to use for the buffer name, instead
+ of the first file name.
+ "term_rows" vertical size to use for the terminal,
+ instead of using 'termwinsize'
+ "term_cols" horizontal size to use for the terminal,
+ instead of using 'termwinsize'
+ "vertical" split the window vertically
+ "curwin" use the current window, do not split the
+ window; fails if the current buffer
+ cannot be |abandon|ed
+ "bufnr" do not create a new buffer, use the
+ existing buffer "bufnr". This buffer
+ must have been previously created with
+ term_dumpdiff() or term_dumpload() and
+ visible in a window.
+ "norestore" do not add the terminal window to a
+ session file
+
+ Each character in the middle part indicates a difference. If
+ there are multiple differences only the first in this list is
+ used:
+ X different character
+ w different width
+ f different foreground color
+ b different background color
+ a different attribute
+ + missing position in first file
+ - missing position in second file
+
+ Using the "s" key the top and bottom parts are swapped. This
+ makes it easy to spot a difference.
+
+ *term_dumpload()*
+term_dumpload({filename} [, {options}])
+ Open a new window displaying the contents of {filename}
+ The file must have been created with |term_dumpwrite()|.
+ Returns the buffer number or zero when it fails.
+ Also see |terminal-diff|.
+
+ For {options} see |term_dumpdiff()|.
+
+ *term_dumpwrite()*
+term_dumpwrite({buf}, {filename} [, {options}])
+ Dump the contents of the terminal screen of {buf} in the file
+ {filename}. This uses a format that can be used with
+ |term_dumpload()| and |term_dumpdiff()|.
+ If the job in the terminal already finished an error is given:
+ *E958*
+ If {filename} already exists an error is given: *E953*
+ Also see |terminal-diff|.
+
+ {options} is a dictionary with these optional entries:
+ "rows" maximum number of rows to dump
+ "columns" maximum number of columns to dump
+
+term_getaltscreen({buf}) *term_getaltscreen()*
+ Returns 1 if the terminal of {buf} is using the alternate
+ screen.
+ {buf} is used as with |term_getsize()|.
+ {only available when compiled with the |+terminal| feature}
+
+term_getansicolors({buf}) *term_getansicolors()*
+ Get the ANSI color palette in use by terminal {buf}.
+ Returns a List of length 16 where each element is a String
+ representing a color in hexadecimal "#rrggbb" format.
+ Also see |term_setansicolors()| and |g:terminal_ansi_colors|.
+ If neither was used returns the default colors.
+
+ {buf} is used as with |term_getsize()|. If the buffer does not
+ exist or is not a terminal window, an empty list is returned.
+ {only available when compiled with the |+terminal| feature and
+ with GUI enabled and/or the |+termguicolors| feature}
+
+term_getattr({attr}, {what}) *term_getattr()*
+ Given {attr}, a value returned by term_scrape() in the "attr"
+ item, return whether {what} is on. {what} can be one of:
+ bold
+ italic
+ underline
+ strike
+ reverse
+ {only available when compiled with the |+terminal| feature}
+
+term_getcursor({buf}) *term_getcursor()*
+ Get the cursor position of terminal {buf}. Returns a list with
+ two numbers and a dictionary: [row, col, dict].
+
+ "row" and "col" are one based, the first screen cell is row
+ 1, column 1. This is the cursor position of the terminal
+ itself, not of the Vim window.
+
+ "dict" can have these members:
+ "visible" one when the cursor is visible, zero when it
+ is hidden.
+ "blink" one when the cursor is blinking, zero when it
+ is not blinking.
+ "shape" 1 for a block cursor, 2 for underline and 3
+ for a vertical bar.
+ "color" color of the cursor, e.g. "green"

+ Get a line of text from the terminal window of {buf}.
+ {buf} is used as with |term_getsize()|.
+
+ The first line has {row} one. When {row} is "." the cursor
+ line is used. When {row} is invalid an empty string is
+ returned.

+ {only available when compiled with the |+terminal| feature}
+
+term_getscrolled({buf}) *term_getscrolled()*
+ Return the number of lines that scrolled to above the top of
+ terminal {buf}. This is the offset between the row number
+ used for |term_getline()| and |getline()|, so that: >
+ term_getline(buf, N)
+< is equal to: >
+ getline(N + term_getscrolled(buf))
+< (if that line exists).
+
+ {buf} is used as with |term_getsize()|.
+ {only available when compiled with the |+terminal| feature}
+
+term_getsize({buf}) *term_getsize()*
+ Get the size of terminal {buf}. Returns a list with two
+ numbers: [rows, cols]. This is the size of the terminal, not
+ the window containing the terminal.
+
+ {buf} must be the buffer number of a terminal window. Use an
+ empty string for the current buffer. If the buffer does not
+ exist or is not a terminal window, an empty list is returned.
+ {only available when compiled with the |+terminal| feature}

+ string is returned.
+ {only available when compiled with the |+terminal| feature}
+
+term_gettitle({buf}) *term_gettitle()*
+ Get the title of terminal {buf}. This is the title that the
+ job in the terminal has set.
+

+ buffer does not exist or is not a terminal window, an empty
+ string is returned.
+ {only available when compiled with the |+terminal| feature}
+
+term_gettty({buf} [, {input}]) *term_gettty()*
+ Get the name of the controlling terminal associated with
+ terminal window {buf}. {buf} is used as with |term_getsize()|.
+
+ When {input} is omitted or 0, return the name for writing
+ (stdout). When {input} is 1 return the name for reading
+ (stdin). On UNIX, both return same name.
+ {only available when compiled with the |+terminal| feature}
+
+term_list() *term_list()*
+ Return a list with the buffer numbers of all buffers for
+ terminal windows.
+ {only available when compiled with the |+terminal| feature}
+
+term_scrape({buf}, {row}) *term_scrape()*
+ Get the contents of {row} of terminal screen of {buf}.
+ For {buf} see |term_getsize()|.
+
+ The first line has {row} one. When {row} is "." the cursor
+ line is used. When {row} is invalid an empty string is

+ to get the individual flags
+ "width" cell width: 1 or 2
+ {only available when compiled with the |+terminal| feature}
+
+term_sendkeys({buf}, {keys}) *term_sendkeys()*
+ Send keystrokes {keys} to terminal {buf}.
+ {buf} is used as with |term_getsize()|.
+
+ {keys} are translated as key sequences. For example, "\<c-x>"
+ means the character CTRL-X.
+ {only available when compiled with the |+terminal| feature}
+
+term_setansicolors({buf}, {colors}) *term_setansicolors()*
+ Set the ANSI color palette used by terminal {buf}.
+ {colors} must be a List of 16 valid color names or hexadecimal
+ color codes, like those accepted by |highlight-guifg|.
+ Also see |term_getansicolors()| and |g:terminal_ansi_colors|.
+
+ The colors normally are:
+ 0 black

+
+ These colors are used in the GUI and in the terminal when
+ 'termguicolors' is set. When not using GUI colors (GUI mode
+ or 'termguicolors'), the terminal window always uses the 16
+ ANSI colors of the underlying terminal.
+ {only available when compiled with the |+terminal| feature and
+ with GUI enabled and/or the |+termguicolors| feature}
+
+term_setkill({buf}, {how}) *term_setkill()*
+ When exiting Vim or trying to close the terminal window in
+ another way, {how} defines whether the job in the terminal can
+ be stopped.
+ When {how} is empty (the default), the job will not be
+ stopped, trying to exit will result in |E947|.
+ Otherwise, {how} specifies what signal to send to the job.
+ See |job_stop()| for the values.
+
+ After sending the signal Vim will wait for up to a second to
+ check that the job actually stopped.
+
+term_setrestore({buf}, {command}) *term_setrestore()*
+ Set the command to write in a session file to restore the job
+ in this terminal. The line written in the session file is: >
+ terminal ++curwin ++cols=%d ++rows=%d {command}
+< Make sure to escape the command properly.
+
+ Use an empty {command} to run 'shell'.
+ Use "NONE" to not restore this window.
+ {only available when compiled with the |+terminal| feature}
+
+term_setsize({buf}, {rows}, {cols}) *term_setsize()* *E955*
+ Set the size of terminal {buf}. The size of the window
+ containing the terminal will also be adjusted, if possible.
+ If {rows} or {cols} is zero or negative, that dimension is not
+ changed.
+
+ {buf} must be the buffer number of a terminal window. Use an
+ empty string for the current buffer. If the buffer does not
+ exist or is not a terminal window, an error is given.
+ {only available when compiled with the |+terminal| feature}
+
+term_start({cmd} [, {options}]) *term_start()*
+ Open a terminal window and run {cmd} in it.
+
+ {cmd} can be a string or a List, like with |job_start()|. The
+ string "NONE" can be used to open a terminal window without
+ starting a job, the pty of the terminal can be used by a
+ command like gdb.
+
+ Returns the buffer number of the terminal window. If {cmd}
+ cannot be executed the window does open and shows an error
+ message.
+ If opening the window fails zero is returned.
+
+ {options} are similar to what is used for |job_start()|, see
+ |job-options|. However, not all options can be used. These
+ are supported:
+ all timeout options
+ "stoponexit", "cwd", "env"
+ "callback", "out_cb", "err_cb", "exit_cb", "close_cb"
+ "in_io", "in_top", "in_bot", "in_name", "in_buf"
+ "out_io", "out_name", "out_buf", "out_modifiable", "out_msg"
+ "err_io", "err_name", "err_buf", "err_modifiable", "err_msg"
+ However, at least one of stdin, stdout or stderr must be
+ connected to the terminal. When I/O is connected to the
+ terminal then the callback function for that part is not used.
+
+ There are extra options:
+ "term_name" name to use for the buffer name, instead
+ of the command name.
+ "term_rows" vertical size to use for the terminal,
+ instead of using 'termwinsize'
+ "term_cols" horizontal size to use for the terminal,
+ instead of using 'termwinsize'
+ "vertical" split the window vertically; note that
+ other window position can be defined with
+ command modifiers, such as |:belowright|.
+ "curwin" use the current window, do not split the
+ window; fails if the current buffer
+ cannot be |abandon|ed
+ "hidden" do not open a window
+ "norestore" do not add the terminal window to a
+ session file
+ "term_kill" what to do when trying to close the
+ terminal window, see |term_setkill()|
+ "term_finish" What to do when the job is finished:
+ "close": close any windows
+ "open": open window if needed
+ Note that "open" can be interruptive.
+ See |term++close| and |term++open|.
+ "term_opencmd" command to use for opening the window when
+ "open" is used for "term_finish"; must
+ have "%d" where the buffer number goes,
+ e.g. "10split|buffer %d"; when not
+ specified "botright sbuf %d" is used
+ "eof_chars" Text to send after all buffer lines were
+ written to the terminal. When not set
+ CTRL-D is used on MS-Windows. For Python
+ use CTRL-Z or "exit()". For a shell use
+ "exit". A CR is always added.
+ "ansi_colors" A list of 16 color names or hex codes
+ defining the ANSI palette used in GUI
+ color modes. See |g:terminal_ansi_colors|.
+ "tty_type" (MS-Windows only): Specify which pty to
+ use. See 'termwintype' for the values.
+
+ {only available when compiled with the |+terminal| feature}
+
+term_wait({buf} [, {time}]) *term_wait()*
+ Wait for pending updates of {buf} to be handled.
+ {buf} is used as with |term_getsize()|.
+ {time} is how long to wait for updates to arrive in msec. If
+ not set then 10 msec will be used.
+ {only available when compiled with the |+terminal| feature}
