448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	11 * Terminal window support, see ":help :terminal".
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	12 *
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	13 * There are three parts:
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	14 * 1. Generic code for all systems.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	15 * Uses libvterm for the terminal emulator.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	16 * 2. The MS-Windows implementation.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	17 * Uses winpty.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	18 * 3. The Unix-like implementation.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	19 * Uses pseudo-tty's (pty's).
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	20 *
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	21 * For each terminal one VTerm is constructed. This uses libvterm. A copy of
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	22 * this library is in the libvterm directory.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	23 *
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	24 * When a terminal window is opened, a job is started that will be connected to
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	25 * the terminal emulator.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	26 *
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	27 * If the terminal window has keyboard focus, typed keys are converted to the
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	28 * terminal encoding and writing to the job over a channel.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	29 *
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	30 * If the job produces output, it is written to the terminal emulator. The
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	31 * terminal emulator invokes callbacks when its screen content changes. The
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	32 * line range is stored in tl_dirty_row_start and tl_dirty_row_end. Once in a
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	33 * while, if the terminal window is visible, the screen contents is drawn.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	34 *
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	35 * When the job ends the text is put in a buffer. Redrawing then happens from
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	36 * that buffer, attributes come from the scrollback buffer tl_scrollback.
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	37 * When the buffer is changed it is turned into a normal buffer, the attributes
448aef880252 normalize line endings Christian Brabandt <cb@256bit.org> parents: 32481 diff changeset	38 * in tl_scrollback are no longer used.
