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.

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.

- 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

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.

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 @ ..."

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

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.

This is required to be compatible with plugins that ask user questions at

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).

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.

- 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

Now all terminal-handling code was moved to src/nvim/tui, which implements a
new terminal UI based on libtermkey and unibilium

non-optional.

- 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

- 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

Neovim always ships with all features[0], so this serves no purpose.
Besides, this always evaluated to true.

- 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.

Notes regarding the removal of specific items:

- mch_check_win(): doesn't exist anymore.
- Comment in ex_cmds.c: It seems the context for this comment was
removed, but the comment was inadvertantly left alone.

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.

Move general initialization functions to early_init, which simplifies
test/unit/helpers.lua, which requires all these functions.

These functions only used to call another os_* function, so remove them and

Instead of building all metadata from msgpack-gen.lua, we now merge the
generated part with manual information(such as types and features). The metadata
is accessible through the api method `vim_get_api_info`.
This was done to simplify the generator while also increasing flexibility(by
being able to add more metadata)
|
| |
|
|
|
| |
--embedded-mode -> --embed
--api-msgpack-metadata -> --api-info
|
| | |
|
| | |
|
| |
|
|
|
| |
This option makes nvim run in "embedded mode", which creates an API channel via
stdin/stdout and disables all terminal-related code
