* main: Initialize event loop before command_line_scanThiago de Arruda2015-08-21
| | | | | | | | The call to `event_init()` was too late. `command_line_scan()` in `main()` could already need the loop initialized. Ref https://github.com/neovim/neovim/issues/3045#issuecomment-123405833. A consequence of this change is that it was necessary to move the `channel_from_stdio()` call to `command_line_scan()` when embedded_mode is set.
* 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.
* Source provider at start if &cb is set #3025Marco Hinz2015-07-20
| | | | | | | | | | | | | The main problem is that <c-c> is a default mapping but also sets got_int. Because of the former, normal_cmd() is kicked off which eventually leads to sourcing the clipboard provider. But due to the latter, do_source() throws an error, because got_int is set. This is a temporary workaround and sources the clipboard provider before main_loop(), if &clipboard is set. References #3023.
* job: Replace by a better process abstraction layerThiago de Arruda2015-07-17
| | | | | | | | | | | | | - New libuv/pty process abstraction with simplified API and no globals. - Remove nvim/os/job*. Jobs are now a concept that apply only to programs spawned by vimscript job* functions. - Refactor shell.c/channel.c to use the new module, which brings a number of advantages: - Simplified API, less code - No slots in the user job table are used - Not possible to acidentally receive data from vimscript - Implement job table in eval.c, which is now a hash table with unilimited job slots and unique job ids.
* 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.
* os/fs: Use module-local uv_loop_t instanceThiago de Arruda2015-07-01
| | | | | | This event loop is just a stub instance used in synchronous libuv function calls, it needs to be decoupled from the main event loop in order to run it from another thread.
* Passing by: Remove X_LOCALE refsMichael Reed2015-05-30
| | | | We don't link to any X11 libs, so this is most likely unneeded.
* main.c:mainerr(): Namespace messagesMichael Reed2015-05-30
| | | | | | | | | | Error messages in general should be namespaced, especially in the context of a shell. Given the possibility of a backgrounded job printing messages to standard output/error, namespacing these messages should avoid any confusion as to where the message came from.

* main.c: Simplify error string managementMichael Reed2015-05-30
| | | | | | | | This removes the need for preprocessor defines as array indices, and brings error handling more in line with other files, which for the most most part to use constant strings (also, see `globals.h`). Helped-By: Nicolas Hillegeer <nicolas@hillegeer.com>
* 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().
* input: rename input_{start,stop}_stdin()Justin M. Keyes2015-05-27
| | | | | - "stdin" is misleading because it may read from stdout or stderr - also remove some unused includes
* input: stream_set_blocking(): libuv implJustin M. Keyes2015-05-27
| | | | | | | | | - Create a private libuv loop instead of re-using uv_default_loop(), to avoid conflict[1] with existing watcher(s) on the fd. - Expose the global "input" fd as a getter instead of a mutable global. [1] .deps/build/src/libuv/src/unix/core.c:833: uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.
* input: set input stream to blocking on exitJustin M. Keyes2015-05-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If stdin is non-blocking, many tools (e.g. cat(1), read(1)) which assume that stdin is blocking, will break in odd ways: read: read error: 0: Resource temporarily unavailable cat: -: Resource temporarily unavailable rm: error closing file libuv puts stdin in nonblocking mode, and leaves it that way at exit (this is apparently by design). So, before this commit, this always works (because the shell clobbers O_NONBLOCK): $ nvim --cmd q $ read ...but these forms do _not_ work: $ nvim --cmd q && read $ echo foo | nvim --cmd q && read $ nvim && read After this commit, all of the above forms work. Background: https://github.com/fish-shell/fish-shell/commit/437b4397b9cf273922ce7b414bf6626845f15ad0#diff-41f4d294430cd8c36538999d62681ae2 https://github.com/fish-shell/fish-shell/issues/176#issuecomment-15800155 - bash (and other shells: zsh, tcsh, fish), upon returning to the foreground, always sets fd 0 back to blocking mode. This practice only applies to stdin, _not_ stdout or stderr (in practice these fds may be affected anyways). - bash/zsh/tcsh/fish do _not_ restore the non-blocking status of stdin when _resuming a job_. - We do _not_ save/restore the original flags visible to fcntl(F_[SG]ETFL), because (counterintuitively) that isn't expected. Helped-by: oni-link <knil.ino@gmail.com> Closes #2086 Closes #2377 --- Note: The following implementation of stream_set_blocking() was discarded, because it resulted in a failed libuv assertion[1]: int stream_set_blocking(int fd, bool blocking) { uv_pipe_t stream; uv_pipe_init(uv_default_loop(), &stream, 0); uv_pipe_open(&stream, fd); int retval = uv_stream_set_blocking((uv_stream_t *)&stream, blocking); uv_close((uv_handle_t *)&stream, NULL); return retval; } [1] .deps/build/src/libuv/src/unix/core.c:833: uv__io_stop: Assertion `loop->watchers[w->fd] == w' failed.

* 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.
* os_scandir: fname_case -> path_fix_caseScott Prager2015-03-31
| | | | | | | | | | Use os_scandir(). fname_case() only gets used when `defined(USE_FNAME_CASE)` (on operating systems with case-insensitive file systems), but may be useful in other contexts, so move it to path.c. (See the TODO.) Remove the unused parameter, len.
* eval: Refactor vimscript job control APIThiago de Arruda2015-03-29
| | | | | | | | | | - Remove JobActivity autocmd and v:job_data variable - Simplify `jobstart` to receive: - An argument vector - An optional dictionary which may contain any of the current `jobstart` options plus `on_stdout`, `on_stderr` and `on_exit` callbacks. - Refactor and add more job tests - Update documentation
* terminal: New module that implements a terminal emulatorThiago de Arruda2015-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit integrates libvterm with Neovim and implements a terminal emulator with nvim buffers as the display mechanism. Terminal buffers can be created using any of the following methods: - Opening a file with name following the "term://[${cwd}//[${pid}:]]${cmd}" URI pattern where: - cwd is the working directory of the process - pid is the process id. This is just for use in session files where a pid would have been assigned to the saved buffer title. - cmd is the command to run - Invoking the `:terminal` ex command - Invoking the `termopen` function which returns a job id for automating the terminal window. Some extra changes were also implemented to adapt with terminal buffers. Here's an overview: - The `main` function now sets a BufReadCmd autocmd to intercept the term:// URI and spawn the terminal buffer instead of reading the file. - terminal buffers behave as if the following local buffer options were set: - `nomodifiable` - `swapfile` - `undolevels=-1` - `bufhidden=hide` - All commands that delete buffers(`:bun`, `:bd` and `:bw`) behave the same for terminal buffers, but only work when bang is passed(eg: `:bwipeout!`) - A new "terminal" mode was added. A consequence is that a new set of mapping commands were implemented with the "t" prefix(tmap, tunmap, tnoremap...) - The `edit` function(which enters insert mode) will actually enter terminal mode if the current buffer is a terminal - The `put` operator was adapted to send data to the terminal instead of modifying the buffer directly. - A window being resized will also trigger a terminal resize if the window displays the terminal.
* doc: Misc. cleanupJustin M. Keyes2015-03-24
| | | | | | | | | | Add missing parentheses and whatnot, move dangling comment, etc. Some specific items worth mentioning: Fixed some references to non-existent tags, found via `make html` msgpack_rpc/channel.c: ELOG already prefixes each line with "error @ ..."

* refactor: split some more functions from misc1.cbobtwinkles2015-03-24
| | | | | | | | | | | This commit pulls the some environment-variable handling functions out of misc1.c and in to os/env.c. Previously submited as #1231, this is the start of a patch series that does that work based on a more up-to-date master branch. Major tasks accomplished: - move functions and fix includes - fix clint/clang analysis warnings - correct documentation comments
* main: Simplify code that deals with early user inputThiago de Arruda2015-03-18
| | | | | | | | | A read stream will be started before the first ex command is processed. This stream will be used to read early user input before handling control over to the UI module. Which stdio stream will be used depends on which types of file descriptors are connected, and whether the "-" argument was passed.
* main: Start stdin before sourcing startup scriptsThiago de Arruda2015-03-17
| | | | | This is required to be compatible with plugins that ask user questions at startup(eg: vim-addon-local-vimrc)
* 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).
* Interface cleanup: Symlink handling & docsMichael Reed2015-03-12
| | | | | | | | | | | | | | | | | | | | | | This removes the ability to start nvim via the following aliases in favor of just using their command line arguments: ex vim -e exim vim -E view vim -R gvim vim -g gex vim -eg gview vim -Rg rvim vim -Z rview vim -RZ rgvim vim -gZ rgview vim -RgZ This also removes Vi mode (-v) for consistency. From ':help -v': -v Start Ex in Vi mode. Only makes a difference when the executable is called "ex" or "gvim". For gvim the GUI is not started if possible.
* 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
* 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`)
* Remove vimdiffMichael Reed2015-02-03
| | | | | | | While we're here: - Remove references to the '+diff' feature, which has since been made non-optional. - Update a few Vim instances with Nvim.
* main.c: usage() improvementMichael Reed2015-02-03
| | | | | | | | | | | | | | | - Factor out main_msg() in favor of mch_msg() and manual indentation, as to provide a much closer representation to the actual output of '--help'. 'gcc -E' reveals that main_msg() only consists of 3 printf calls anyways. - Factor out for loop used for printing top part of usage text; just print the text normally. usage() text: - Don't print the version; that's what '--version' is for. - Be consistent about nomenclature, e.g. '<arg>' denotes required argument, '-h | --help' denotes '-h' and '--help' are equivalent, etc. - Change some instances of vim{,rc,info} to nvim
* main.c: Misc. improvementsMichael Reed2015-01-23
| | | | | | | | | | | | | | | | | | | | | | | | - Constify parameters and reduce char_u usage - Modernize function signatures - Modernize function comment blocks, rewriting if needed - Factor out mainerr_arg_missing(); all the other ME_* macros lack such a wrapper function. main_errors[] - Remove unneeded parentheses - Remove an unused error string and its respective macro mainerr() - Don't print version when called. mainerr() only handles errors related to command line arguments, so the version isn't much help at all. - Changed 'vim' instance to 'nvim' Misc. - Remove duplicate include - Replace unneeded 'inttypes.h' include with 'stdint.h' - Remove stray comments - Remove excessive newlines
