/*
|
|
* Terminal window support, see ":help :terminal".
|
|
*
|
|
* There are three parts:
|
|
* 1. Generic code for all systems.
|
|
* Uses libvterm for the terminal emulator.
|
|
* 2. The MS-Windows implementation.
|
|
* Uses winpty.
|
|
* 3. The Unix-like implementation.
|
|
* Uses pseudo-tty's (pty's).
|
|
*
|
|
* For each terminal one VTerm is constructed. This uses libvterm. A copy of
|
|
* this library is in the libvterm directory.
|
|
*
|
|
* When a terminal window is opened, a job is started that will be connected to
|
|
* the terminal emulator.
|
|
*
|
|
* If the terminal window has keyboard focus, typed keys are converted to the
|
|
* terminal encoding and writing to the job over a channel.
|
|
*
|
|
* If the job produces output, it is written to the terminal emulator. The
|
|
* terminal emulator invokes callbacks when its screen content changes. The
|
|
* line range is stored in tl_dirty_row_start and tl_dirty_row_end. Once in a
|
|
* while, if the terminal window is visible, the screen contents is drawn.
|
|
*
|
|
* When the job ends the text is put in a buffer. Redrawing then happens from
|
|
* that buffer, attributes come from the scrollback buffer tl_scrollback.
|
|
* When the buffer is changed it is turned into a normal buffer, the attributes
|
|
* in tl_scrollback are no longer used.
