+
+
+Terminal window support *terminal*
+
+
+WARNING: THIS IS ONLY PARTLY IMPLEMENTED, ANYTHING CAN STILL CHANGE
+
+
+1. Basic use |terminal-use|
+2. Remote testing |terminal-testing|
+3. Debugging |terminal-debug|
+
+{Vi does not have any of these commands}
+
+==============================================================================
+1. Basic use *terminal-use*
+
+This feature is for running a terminal emulator in a Vim window. A job can be
+started connected to the terminal emulator. For example, to run a shell: >
+ :term bash
+
+Or to run a debugger: >
+ :term gdb vim
+
+The job runs asynchronously from Vim, the window will be updated to show
+output from the job, also while editing in any other window.
+
+When the keyboard focus is in the terminal window, typed keys will be send to
+the job. This uses a pty when possible.
+
+Navigate between windows with CTRL-W commands (and mouse).
+E.g. CTRL-W CTRL-W moves focus to the next window.
+
+Option 'termkey'
+Specify key for Vim command in terminal window. local to window.
+Default is CTRL-W.
+
+Option 'termsize'
+Specify terminal size. Local to window.
+When empty the terminal gets the size from the window.
+When set (e.g., "24x80") the terminal size is fixed. If the window is smaller
+only the top-left part is displayed. (TODO: scrolling?)
+
+Syntax ~
+ *:ter* *:terminal*
+:terminal[!] [command] Open a new terminal window.
+
+ If [command] is provided run it as a job and connect
+ the input and output to the terminal.
+ If [command] is not given the 'shell' option is used.
+
+ A new buffer will be created, using [command] or
+ 'shell' as the name. If a buffer by this name already
+ exists a number is added in parenthesis.
+ E.g. if "gdb" exists the second terminal buffer will
+ use "gdb (1)".
+
+ The window can be closed, in which case the buffer
+ becomes hidden. The command will not be stopped. The
+ `:buffer` command can be used to turn the current
+ window into a terminal window, using the existing
+ buffer. If there are unsaved changes this fails, use
+ ! to force, as usual.
+
+Resizing ~
+
+The size of the terminal can be in one of three modes:
+
+1. The 'termsize' option is empty: The terminal size follows the window size.
+ The minimal size is 2 screen lines with 10 cells.
+
+2. The 'termsize' option is "rows*cols", where "rows" is the minimal number of
+ screen rows and "cols" is the minial number of cells.
+
+3. The 'termsize' option is "rowsXcols" (where the x is upper or lower case).
+ The terminal size is fixed to the specified number of screen lines and
+ cells. If the window is bigger there will be unused empty space.
+
+If the window is smaller than the terminal size, only part of the terminal can
+be seen (the lower-left part).
+
+The |term_getsize()| function can be used to get the current size of the
+terminal. |term_setsize()| can be used only when in the first or second mode,
+not when 'termsize' is "rowsXcols".
+
+==============================================================================
+2. Remote testing *terminal-testing*
+
+Most Vim tests execute a script inside Vim. For some tests this does not
+work, running the test interferes with the code being tested. To avoid this
+Vim is executed in a terminal window. The test sends keystrokes to it and
+inspects the resulting screen state.
+
+Functions ~
+
+term_sendkeys() send keystrokes to a terminal
+term_wait() wait for screen to be updated
+term_scrape() inspect terminal screen
+
+
+==============================================================================
+3. Debugging *terminal-debug*
+
+The Terminal debugging plugin can be used to debug a program with gdb and view
+the source code in a Vim window. For example: >
+
+ :TermDebug vim
+
+This opens three windows:
+- A terminal window in which "gdb vim" is executed. Here you can directly
+ interact with gdb.
+- 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.
+- A normal Vim window used to show the source code. When gdb jumps to a
+ source file location this window will display the code, if possible. Values
+ of variables can be inspected, breakpoints set and cleared, etc.
+
+This uses two terminal windows. To open the gdb window: >
+ :term gdb [arguments]
+To open the terminal to run the tested program |term_open()| is used.
