|\ | | | | Rename main loop variable from loop to main_loop
| * *: Rename main loop variable from loop to main_loopZyX2016-05-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current name is inappropriate for the following reasons: 1. It is often masked by local `loop` variables. 2. It cannot be searched for. There are many `loop` variables where `loop` is some local variable. There are many cases when “loop” word is used in a comment. 3. It is in any case bad idea to use a generic name as a name of the global variable. Best if global has module prefix: this is why it is in `main.h`: `main_loop` both stands for “a main loop” and “a loop defined in `main.*`”. Since I have no idea how to list every occurrence of this variable method used to rename it is “remove it from globals.h, try to compile, fix errors”. Thus if some occurrence was hidden under false `#if` branch it was not replaced.

* *: Fix new linter errorsZyX2016-05-01
| | | | Originally there were 128 new errors, so I thought this is a good idea to fix all of them. Of course, this commit also fixes many suppressed errors.
* Do not use TMUX_WRAP for DECSCUSR sequenceDaniel Hahler2016-01-29
| | | | | | | | | | | Wrapping it will send it to the terminal "directly", which might change the cursor of another pane, e.g. when starting Neovim and changing to another pane directly. tmux has a terminfo extension (Ss/Se) to handle and translate the DECSCUSR sequences internally. This can be controlled through `terminal-overrides`, but does not appear to be able to handle the uncommon sequences for Konsole.
* Implement handling of terminal focus eventsJoe Hermaszewski2015-11-17
| | | | | | | | | | | | | | | | | | | | Two new keys have been added to key_name_entry in keymap.c: `FocusGained` and `FocusLost`. Two cases have been added to the key handing switch in edit.c each applying their respective autocmds. In normal.c two functions have been added alongside nv_cursorhold doing a similar job of applying the autocmd for the appropriate key. tui/input.c has a new function `handle_focus_event` which eats either of the control sequences for focus gained or lost. This function is checked before handle_bracketed_paste and handle_forced_escape. tui.c registers neovim as able to receive these control sequences in terminfo_start and undoes that in terminfo_stop. Closes #2302
* ui_bridge: Fix race condition that results in deadlock.Thiago de Arruda2015-10-31
| | | | Fixed by waiting until the UI thread finishes processing events. Close #3541.

* tui: Fix abort when stdout and stderr are not tty.Thiago de Arruda2015-10-29
| | | | | The abort came from using libuv tty handle on non-tty fd. Use uv_pipe_t in these cases. Also add simple test for this case.
* tui: Flush input on timer_cbThiago de Arruda2015-10-12
| | | | | | This is required to have <esc> working correctly when the `ttimeout`/`ttimeoutlen` options are set. Ref: https://github.com/neovim/neovim/issues/2093#issuecomment-146506480

| | | | | Take the return value of input_enqueue into consideration, waiting for the main thread to consume input. Close #1714 #3377.
* tui: Don't use 'pastetoggle' for automatic pastingThiago de Arruda2015-10-01
| | | | | | | Add a new special key that can be used by UIs to toggle the 'paste' option and use it in the TUI instead of the user's 'pastetoggle' value. Close #2843 #2092

* tui: Move screen state tracking to new "ugrid" moduleThiago de Arruda2015-09-06
| | | | | The ugrid module implements a unicode "drawing" grid and is used to store TUI screen state. Later this module will be reused in other layers.
* tui: move term_input.inl into the input.c moduleThiago de Arruda2015-09-06

* tui/remote_ui: Fix some regressionsThiago de Arruda2015-08-21
| | | | | | | | - Explicitly set the SignalWatcher event queue. Without this, the watcher will publish events to the fast queue, resulting in resize bugs for certain terminals(#2322). - Set `async = false` to the `remote_ui_attach` handler(It was a deferred before, this is the new equivalent)
* Notify attached UIs whenever menus changeRobin Allen2015-08-21
| | | | | This adds a redraw notification "update_menu" which is sent whenever Vim's menus are changed by the :menu command and friends.
* tui: restore got_winch in sigwinch_cb #3171Felipe Morales2015-08-15
| | | | Fixes minor regression from #3145.
* rstream: Pass read count to read eventsThiago de Arruda2015-08-13
| | | | This is necessary to keep events in the same order received from the OS.
* event: Refactor async event processingThiago de Arruda2015-08-13
| | | | | | | | | | - Improve the implementation of deferred/immediate events. - Use the new queue module to change how/when events are queued/processed by giving a private queue to each emitter. - Immediate events(which only exist to break uv_run recursion) are now represented in the `loop->fast_events` queue. - Events pushed to child queues are propagated to the event loop main queue and processed as K_EVENT keys.

* tui: Fix terminal detection for cursor shape #3129Keerthan Jaic2015-08-04
| | | | | Default to DECSCUSR, except for known cases where other codes are used or changing cursor shape is unsupported
* tui: Use underline cursor in Replace modeOmar Sandoval2015-07-26
| | | | | | | This is a port of my original contribution to Vim, added in 7.4.687 (https://github.com/vim/vim/commit/v7-4-687). The TUI code has been heavily refactored (see esp. 25ceadab37edba13f5afa78d8b4723da03ef35f0), so this required some translation, but the logic is the same.
* api: Simplify UI API on mode changeOmar Sandoval2015-07-26
| | | | | | | Currently, there are two functions in the UI API that are called when the mode changes: insert_mode() and normal_mode(). These can be folded into a single mode_change() entrypoint which can do whatever it wants based on the mode it is passed, limited to INSERT and NORMAL for now.
* options,tui: don't hardcode default terminal sizeFelipe Morales2015-07-21
| | | | also, include some checks.
* tui: respect the 'co' and 'lines' options on startupFelipe Morales2015-07-21
| | | | | `nvim --cmd "set co=... lines="` didn't work as expected, and forced to set those options on VimEnter or afterwards.
* tui: send resize sequences to the terminalFelipe Morales2015-07-21
| | | | | | | | Neither setting the 'columns' and 'lines' options nor using the `:winsize` command resized the terminal window, which caused display glitches. Re: #2863
* tui: Unconditionally enable bracketed paste mode #3060crondog2015-07-21
| | | | | | | | | There are more terminals which have bracketed paste support and it doesnt seem to do any harm with terminals that dont support it eg screen Reviewed-by: Marco Hinz <mh.codebro@gmail.com> Reviewed-by: Michael Reed <Pyrohh@users.noreply.github.com> "+1 Let's see what happens" Justin M.

* rstream/wstream: Unify structures and simplify APIThiago de Arruda2015-07-17
| | | | | | | | | | | | | - Simplify RStream/WStream API and make it more consistent with libuv. - Move into the event loop layer(event subdirectory) - Remove uv_helpers module. - Simplify job/process internal modules/API. - Unify RStream and WStream into a single structure. This is necessary because libuv streams can be readable and writable at the same time(and because the uv_helpers.c hack to associate multiple streams with libuv handle was removed) - Make struct definition public, allowing more flexible/simple memory management by users of the module. - Adapt channel/job modules to cope with the changes.
* event loop: New abstraction layer with refactored time/signal APIThiago de Arruda2015-07-17
| | | | | | | | | | - Add event loop abstraction module under src/nvim/event. The src/nvim/event/loop module replaces src/nvim/os/event - Remove direct dependency on libuv signal/timer API and use the new abstraction instead. - Replace all references to uv_default_loop() by &loop.uv, a new global variable that wraps libuv main event loop but allows the event loop functions to be reused in other contexts.
* rbuffer: Fix for problems with escape input sequences.oni-link2015-07-07
| | | | | | | | | | | If at least two escape sequences were read, the beginning of the second sequence would be off by one and the sequence would be misinterpreted. An escape sequence could be split in two parts and be misinterpreted, when saved in a ring buffer with wrap around. Fixes #2936
* rbuffer: Reimplement as a ring buffer and decouple from rstreamThiago de Arruda2015-07-01
| | | | | | | | | | | | | | | | | | | | Extract the RBuffer class from rstream.c and reimplement it as a ring buffer, a more efficient version that doesn't need to relocate memory. The old rbuffer_read/rbuffer_write interfaces are kept for simple reading/writing, and the RBUFFER_UNTIL_{FULL,EMPTY} macros are introduced to hide wrapping logic when more control is required(such as passing the buffer pointer to a library function that writes directly to the pointer) Also add a basic infrastructure for writing helper C files that are only compiled in the unit test library, and use this to write unit tests for RBuffer which contains some macros that can't be accessed directly by luajit.

* getenv: return NULL if empty #2574Scott Prager2015-05-29
| | | | | | Making an environment variable empty can be a way of unsetting it for platforms that don't support unsetenv(). In most cases, we treat empty variables as having been unset. For all others, use os_env_exists().

* tui: defer resize event #2738Daniel Hahler2015-05-25
| | | | | | | When maximizing the window, often only lines would be detected properly with the `try_resize` handler being called immediately. Fixes https://github.com/neovim/neovim/issues/2322.
* memory: Add `free` wrapper and refactor project to use itThiago de Arruda2015-04-13
| | | | | | We already use wrappers for allocation, the new `xfree` function is the equivalent for deallocation and provides a way to fully replace the malloc implementation used by Neovim.
* Job control: reset mouse support after foregroundingMarco Hinz2015-04-06
| | | | | | Reset mouse support to whatever was used before the process was suspended. References #2335.
* tui: Fix reading when stdin is not a ttyThiago de Arruda2015-03-26
| | | | | | | | | | | | | | | | | | Instead of selecting stderr on startup if stdin is not a tty, first try reading from it and only switch to stderr when reading fails. With this behavior we support commands like: ``` echo q | nvim -es ``` and ``` ls *.md | xargs nvim ``` Fixed small bugs in rstream.c to make this happen.
* tui: Add support for true color terminalsThiago de Arruda2015-03-20
| | | | | | | | | This is enabled by setting the `$NVIM_TUI_ENABLE_TRUE_COLOR` environment variable, eg: ``` $ NVIM_TUI_ENABLE_TRUE_COLOR=1 nvim ```
* 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.
* tui.c: Send fewer cursor-hide commands to the terminal.oni-link2015-03-18
| | | | | | | | | | | | | | | | | | | Since #2158 all connected UIs are informed about the busy state of nvim. This can be used to decide whether to hide or show the cursor (in one place). In the TUI, this is tui_flush(). To prevent cursor flashing, the terminal is always redrawn with an invisible cursor. After that the cursor is shown if necessary. In the current implementation a cursor-hide command will always be the first command in the next redraw, to prevent flashing. This is not necessary. Instead we start the TUI with a hidden cursor and only need to hide the cursor in the next redraw, if the cursor was shown in the last redraw. Otherwise the cursor is still hidden. So instead of sending every redraw the cursor-hide command, we only need to send the command while not busy(a state in nvim with low frequency).
* 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).
