* tui: make termkey use utf-8 mode when &encoding=utf-8 #2469Björn Linse2015-06-13

* ui: Schedule screen refreshs to run in the event loopThiago de Arruda2015-03-25
| | | | | This is required to avoid event loop recursion due to indirect calls to os_breakcheck by screenalloc
* ui: Refactor so that busy state won't be the defaultThiago de Arruda2015-03-18
| | | | | | | | | | | Even though assuming nvim is busy most times is simpler, it has a problem: A lot of unnecessary busy_start/busy_stop notifications are sent to the UI. That's because in the majority of scenarios almost no time is spent between `event_poll` calls. This restores the normal behavior which is to call busy_start only when nvim is going to perform some task that can take a significant amount of time. Also improve the usage of buffering in the TUI when changing the cursor state.
* ui: Only call ui_flush when the busy state changesThiago de Arruda2015-03-16
| | | | | Also add back the `ui_flush` call to `get_keystroke`. Its necessary to display prompt messages correctly.
* ui: Replace cursor_{on,off} by busy_{stop,start}Thiago de Arruda2015-03-15
| | | | | | | | | | | | | | | | | | | | | | | | Switching cursor off is only necessary in two occasions: - When redrawing to avoid terminal flickering - When the editor is busy The first can now be handled by the TUI, so most calls to ui_cursor_off can be removed from the core. So, before this commit it was only necessary to switch the cursor off to notify the user that nvim was running some long operation. Now the cursor_{on,off} functions have been replaced by busy_{stop,start} which can be handled in a UI-specific way(turning the cursor off or showing a busy indicator, for example). To make things even more simpler, nvim is always busy except when waiting for user input or other asynchronous events: It automatically switches to a non-busy state when the event loop is about to be entered for more than 100 milliseconds. `ui_busy_start` can be called when its not desired to change the busy state in the event loop (As its now done by functions that perform blocking shell invocations).

* refactor: Remove term modules and termcap optionsThiago de Arruda2015-02-21
| | | | | | | | | | | | | | | - Removed term.c, term.h and term_defs.h - Tests for T_* values were removed. screen.c was simplified as a consequence(the best strategy for drawing is implemented in the UI layer) - Redraw functions now call ui.c functions directly. Updates are flushed with `ui_flush()` - Removed all termcap options(they now return empty strings for compatibility) - &term/&ttybuiltin options return a constant value(nvim) - &t_Co is still available, but it mirrors t_colors directly - Remove cursor tracking from screen.c and the `screen_start` function. Now the UI is expected to maintain cursor state across any call, and reset it when resized. - Remove unused code

* syntax: Refactor to store all term and gui attributes independentlyThiago de Arruda2015-02-16
| | | | | Now the attrentry_T structure will store all attributes in separate fields for cterm and rgb UIs.
* ui: Rewrite the builtin terminal UIThiago de Arruda2015-02-16
| | | | | Now all terminal-handling code was moved to src/nvim/tui, which implements a new terminal UI based on libtermkey and unibilium
* ui: Remove/adapt some old code for a big UI refactorThiago de Arruda2015-02-16
| | | | | | | | | | | | | - Remove abstract_ui global, now it is always active - Remove some terminal handling code - Remove unused functions - Remove HAVE_TGETENT/TERMINFO/TERMIOS/IOCTL #ifdefs - Remove tgetent/terminfo from version.c - Remove curses/terminfo dependencies - Only start/stop termcap when starting/exiting the program - msg_use_printf will return true if there are no attached UIs( messages will be written to stdout) - Remove `ex_winpos`(implement `:winpos` with `ex_ni`)

* main: Fix color schemes for abstract_uiThiago de Arruda2015-01-13
| | | | | | | | | - Set 't_Co' to 256 at startup. The value can be changed by the user for compatibility with terminals that are less capable. - `has('gui_running')` will return 1 if at least one rgb UI is attached. Even though these changes are hacky, they are necessary to make the transition to the new UI architecture smoother.
* ui: Fix redraw bug caused by race conditions with remote clientsThiago de Arruda2015-01-13

* | Cleanup: Rename getdigits() family functions.Eliseo Martínez2015-01-11
| |
* | Cleanup: Refactor getdigits().Eliseo Martínez2015-01-11
|/ | | | | | | | | | | | | | | | Problem : getdigits() currently returns a long, but at most places, return value is casted (unsafely) into an int. Making casts safe would introduce a lot of fuss in the form of assertions checking for limits. Note : We cannot just change return type to int, because, at some places, legitimate long values are used. For example, in diff.c, for line numbers. Solution : Introduce new functions: - get_digits() : Gets an intmax_t from a string. - get_int_digits() : Wrapper for ints. - get_long_digits() : Wrapper for longs. And replace getdigits() invocations by the appropiate wrapper invocations.
* syntax: Use RGB/GUI attribute information for "abstract_ui"Thiago de Arruda2014-12-08
| | | | | | | | Instead of using classic cterm color numbers and attributes, treat "abstract_ui" as a GUI: Pass rgb color numbers and gui attributes when the "highlight_set" UI method is called. The terminal UI will have to translate RGB color information to an appropriate color number, and the "term"/"cterm" :highlight keys will eventually be deprecated.
* ui: Add abstract_ui termcap and split UI layerThiago de Arruda2014-12-08
| | | | | | | | | | | | | | | | | | This is how Nvim behaves when the "abstract_ui" termcap is activated: - No data is written/read to stdout/stdin by default. - Instead of sending data to stdout, ui_write will parse the termcap codes and invoke dispatch functions in the ui.c module. - The dispatch functions will forward the calls to all attached UI instances(each UI instance is an implementation of the UI layer and is registered with ui_attach). - Like with the "builtin_gui" termcap, "abstract_ui" does not contain any key sequences. Instead, vim key strings(<cr>, <esc>, etc) are parsed directly by input_enqueue and the translated strings are pushed to the input buffer. With this new input model, its not possible to send mouse events yet. Thats because mouse sequence parsing happens in term.c/check_termcodes which must return early when "abstract_ui" is activated.

* | ui: Move check_col/check_row functions to mbyte.cThiago de Arruda2014-11-27

| | | | | These functions only used to call another os_* function, so remove them and replace all occurences in the project.
* ui: Remove ui_inchar/ui_char_availThiago de Arruda2014-11-27
| | | | | | | | | Also: - Remove NO_CONSOLE_INPUT/NO_CONSULE preprocessor conditionals - Remove ctrl_c_interrupts variable, check for mapped_ctrl_c directly in process_interrupts() - Move ui_inchar profiling to input_poll which is where Nvim blocks for input.
* Use bool for flags in oparg_T.Scott Prager2014-11-11
| | | | | | | | | | | | | | | | | | | | | | | Several opart_T members like use_reg_one, end_adjusted, empty, is_VIsual, and block_mode, only ever store TRUE or FALSE, so make this constraint explicit by changing them to bools, and TRUE to true and FALSE to false in the context of their uses. The member, inclusive, has several other uses such as in arithmetic equations and one inequality, but every single assignment (obtained with 'grep -r "inclusive \\="') sets it to either TRUE or FALSE. This also implies that the inequality, "oap->end.coladd < oap->inclusive", can only be true when coladd==0 and inclusive==true, so test for that instead. For consistency, change the first argument of findpar (which ends up being inclusive) to bool. Include stdbool.h for consistency with issue #918. This commit shrinks the size of oparg_T from 128 bytes to 112 (-13%) on my machine.
