Add new "splice" interface for tracking buffer changes at the byte
level. This will later be reused for byte-resolution buffer updates.
(Implementation has been started, but using undocumented "_on_bytes"
option now as interface hasn't been finalized).
Use this interface to improve many edge cases of extmark adjustment.
Changed tests indicate previously incorrect behavior. Adding tests for
more edge cases will be follow-up work (overlaps on_bytes tests)
Don't consider creation/deletion of marks an undoable event by itself.
This behavior was never documented, and imposes complexity for little gain.
Add nvim__buf_add_decoration temporary API for direct access to the new
implementation. This should be refactored into a proper API for
decorations, probably involving a huge dict.

Problem: When Normal highlight group defines ctermfg/bg, but other
highlight group lacks ctermfg/bg, nvim_get_hl_by_id(hl_id,
v:false) returns -1 for the missing ctermfg/bg instead of just
omitting it.
Solution: checking for -1 in hlattrs2dict()
fix#11680
- We already find ourselves renaming nvim_execute_lua in tests and
scripts, which suggests "exec" is the verb we actually want.
- Add "exec" verb to `:help dev-api`.
This covers all "small" inserts and deletes in insert mode, as well
as a few more cases like small normal mode deletes
vim-patch:8.1.0678: text properties as not adjusted for inserted text
It is perfectly fine and expected to detach from the screen just by
the UI disconnecting from nvim or exiting nvim. Just keep detach() in
screen_basic_spec, to get some coverage of the detach method itself.
This avoids hang on failure in many situations (though one could argue
that detach() should be "fast", or at least "as fast as resize",
which works in press-return already).
Never use detach() just to change the size of the screen, try_resize()
method exists for that specifically.
Before this, --embed UIs (without --headless) would not trigger UIEnter.
For TUI, maybe UIEnter isn't useful, but:
- It is less "surprising"/special.
- Makes documentation simpler.
- When TUI becomes a coprocess, it will happen anyway.
- Rename `meth_pcall`.
- Make `pcall_err` raise an error if the function does not fail.
- Add `vim.pesc()` to treat a string as literal where a Lua pattern is
expected.
- Always load files when cleaning up jumplist.
- For Shada: avoids writing duplicate entries, which happens when you read
from a shada file with duplicate entries (merging the jumplist while
writing sometimes produces duplicate entries, bug?) and then write right
away (i.e.: without any `:jumps`, `getjumplist()`, or any jump movement,
that is: nothing that calls `cleanup_jumplist` with `loadfiles == true`).
- For Context: avoids non-idempotent behavior for the same reason (i.e.:
first call to `shada_encode_jumps` does not remove duplicate entries).
- Do not set pcmark when dumping jumplist for Context.
- Retrieving current Context shouldn't add an entry to the jumplist
(which will be removed by a subsequent `cleanup_jumplist` anyway, i.e.:
tail entry matching current position), just act like `getjumplist` for
instance.
luassert uses 3 by default, which is often not enough.
Instead of documenting how to increase it, let's use a more fitting
(sane) default of 100 levels.
NB: the `!(flags & SOPT_GLOBAL)` exception is for 'statusline'.
Because `:set statusline=...` sets the global value for _all_ windows,
`:setlocal` is the best we can do there. This is a one-of-a-kind option
that doesn't work like any other option.
- All "chunks" in a paste-stream should form a single undo-block. Side
effect of 7a85792884 was to create an undo-block for each chunk.
- Also: remove old :redraw force logic, irrelevant after 7a85792884.
- Introduce TRY_WRAP() until we have an *architectural* solution.
- TODO: bfredl idea: prepare error-handling at "top level" (nv_event).
- nvim_paste(): Revert luaeval() hack (see parent commit).
- With TRY_WRAP() in nvim_put(), 'nomodifiable' error now correctly
"bubbles up".
- nvim_paste(): Marshal through luaeval() instead of nvim_execute_lua()
because the latter seems to hide some errors.
- Handle 'nomodifiable' in `nvim_put()` explicitly.
- Require explicit `false` from `vim.paste()` in order to "cancel",
otherwise assume true ("continue").
- Show error only once per "paste stream".
- Drain remaining chunks until phase=3.
- Lay groundwork for "cancel".
- Constrain semantics of "cancel" to mean "client must stop"; it is
unrelated to presence of error(s).
Fixes strange behavior where sometimes the buffer contents of a series
of paste chunks (vim._paste) would be out-of-order.
Now the tui_spec.lua screen-tests are much more reliable. But they still
sometimes fail because of off-by-one cursor (caused by "typeahead race"
resulting in wrong mode; fixed later in this patch-series).
Rationale: the purpose of nvim_execute_lua is to simply call lua code with lua
values. If a lua function expects a floating point value, it should be enough
to specify a float as argument to nvim_execute_lua.
However, make sure to preserve the existing roundtripping behavior of
API values when using `vim.api` functions. This is covered by existing
lua/api_spec.lua tests.
There might be an existing job already - maybe due to some other test,
but in this case there was only one failure in the test run.

The test.functional.helpers and test.unit.helpers modules now include
all of the public functions from test.helpers, so there is no need to
separately require('test.helpers').
Automatically include all "global helper" util functions in the
unit.helpers and functional.helpers and modules. So tests don't need to
expicitly do:
local global_helpers = require('test.helpers')
closes#9136
- Treat empty {rhs} like <Nop>
- getchar.c: Pull "repl. MapArg termcodes" into func
The "preprocessing code" surrounding the replace_termcodes calls needs
to invoke replace_termcodes, and also check if RHS is equal to "<Nop>".
To reduce code duplication, factor this out into a helper function.
Also add an rhs_is_noop flag to MapArguments; buf_do_map_explicit
expects an empty {rhs} string for "<Nop>", but also needs to distinguish
that from something like ":map lhs<cr>" where no {rhs} was provided.
- getchar.c: Use allocated buffer for rhs in MapArgs
Since the MAXMAPLEN limit does not apply to the RHS of a mapping (or
else an RHS that calls a really long autoload function from a plugin
would be incorrectly rejected as being too long), use an allocated
buffer for RHS rather than a static buffer of length MAXMAPLEN + 1.
- Mappings LHS and RHS can contain literal space characters, newlines, etc.
- getchar.c: replace_termcodes in str_to_mapargs
It makes sense to do this; str_to_mapargs is, intuitively, supposed to
take a "raw" command string and parse it into a totally "do_map-ready"
struct.
- api/vim.c: Update lhs, rhs len after replace_termcodes
Fixes a bug in which replace_termcodes changes the length of lhs or rhs,
but the later search through the mappings/abbreviations hashtables
still uses the old length value. This would cause the search to fail
erroneously and throw 'E31: No such mapping' errors or 'E24: No such
abbreviation' errors.
- getchar: Create new map_arguments struct
So that a string of map arguments can be parsed into a more useful, more
portable data structure.
- getchar.c: Add buf_do_map function
Exactly the same as the old do_map, but replace the hardcoded references
to the global `buf_T* curbuf` with a function parameter so that we can
invoke it from nvim_buf_set_keymap.
- Remove gettext calls in do_map error handling
Before now, Nvim always degrades UI capabilities to the lowest-common
denominator. For example, if any connected UI has `ext_messages=false`
then `ext_messages=true` requested by any other connected UI is ignored.
Now `nvim_ui_attach()` supports `override=true`, which flips the
behavior: if any UI requests an `ext_*` UI capability then the
capability is enabled (and the legacy behavior is disabled).
Legacy UIs will be broken while a `override=true` UI is connected, but
it's useful for debugging: you can type into the TUI and observe the UI
events from another connected (UI) client. And the legacy UI will
"recover" after the `override=true` UI disconnects.
Example using pynvim:
>>> n.ui_attach(2048, 2048, rgb=True, override=True, ext_multigrid=True, ext_messages=True, ext_popupmenu=True)
>>> while True: n.next_message();
CA_COMMAND_BUSY in nv_event() was carried over from Vim nv_cursorhold()
(ref: e5165bae11). It prevents :startinsert from working during a RPC
call, so remove it.

Loading existing files into a buffer is non-trivial and requires a window.
Creating an unnamed emtpy buffer is trivial and safe though, thus worth a
special case.
Change nvim_buf_set_option to use aucmd_prepbuf. This is necessary
to allow some options to be set on a not yet displayed buffer, such
as 'buftype' option.

Namespaces is a lightweight concept that should be used to group
objects for purposes of bulk operations and introspection. This is
initially used for highlights and virtual text in buffers, and is
planned to also be used for extended marks. There is no plan use them
for privileges or isolation, neither to introduce nanespace-level
options.
