/* vi:set ts=8 sts=4 sw=4 noet: * * VIM - Vi IMproved by Bram Moolenaar * * Do ":help uganda" in Vim to read copying and usage conditions. * Do ":help credits" in Vim to see a list of people who contributed. * See README.txt for an overview of the Vim source code. */ /* * 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. * * TODO: * - When using term_finish "open" have a way to specify how the window is to * be opened. E.g. term_opencmd "10split buffer %d". * - support different cursor shapes, colors and attributes * - make term_getcursor() return type (none/block/bar/underline) and * attributes (color, blink, etc.) * - Make argument list work on MS-Windows. #1954 * - MS-Windows: no redraw for 'updatetime' #1915 * - To set BS correctly, check get_stty(); Pass the fd of the pty. * For the GUI fill termios with default values, perhaps like pangoterm: * http://bazaar.launchpad.net/~leonerd/pangoterm/trunk/view/head:/main.c#L134 * Also get the NL behavior from there. * - do not store terminal window in viminfo. Or prefix term:// ? * - add a character in :ls output * - add 't' to mode() * - set 'filetype' to "terminal"? * - use win_del_lines() to make scroll-up efficient. * - Make StatusLineTerm adjust UserN highlighting like StatusLineNC does, see * use of hightlight_stlnc[]. * - implement term_setsize() * - add test for giving error for invalid 'termsize' value. * - support minimal size when 'termsize' is "rows*cols". * - support minimal size when 'termsize' is empty? * - implement "term" for job_start(): more job options when starting a * terminal. Allow: * "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" * Check that something is connected to the terminal. * Test: "cat" reading from a file or buffer * "ls" writing stdout to a file or buffer * shell writing stderr to a file or buffer * - support ":term NONE" to open a terminal with a pty but not running a job * in it. The pty can be passed to gdb to run the executable in. * - if the job in the terminal does not support the mouse, we can use the * mouse in the Terminal window for copy/paste. * - when 'encoding' is not utf-8, or the job is using another encoding, setup * conversions. * - update ":help function-list" for terminal functions. * - In the GUI use a terminal emulator for :!cmd. * - Copy text in the vterm to the Vim buffer once in a while, so that * completion works. */ #include "vim.h" #if defined(FEAT_TERMINAL) || defined(PROTO) #ifndef MIN # define MIN(x,y) ((x) < (y) ?
