problem: can we have Serde?
solution: we have Serde at home
This by itself is just a change of notation, that could be quickly
merged to avoid messy merge conflicts, but upcoming changes are planned:
- keysets no longer need to be defined in one single file. `keysets.h` is
just the initial automatic conversion of the previous `keysets.lua`.
keysets just used in a single api/{scope}.h can be moved to that file, later on.
- Typed dicts will have more specific types than Object. this will
enable most of the existing manual typechecking boilerplate to be eliminated.
We will need some annotation for missing value, i e a boolean will
need to be represented as a TriState (none/false/true) in some cases.
- Eventually: optional parameters in form of a `Dict opts` final
parameter will get added in some form to metadata. this will require
a discussion/desicion about type forward compatibility.

When a buffer update callback is called, textlock is active so buffer
text cannot be changed, but cursor can still be moved. This can cause
problems when the buffer update is in the middle of an operator, like
the one mentioned in #16729. The solution is to save cursor position and
restore it afterwards, like how cursor is saved and restored when
evaluating an <expr> mapping.

Problem:
The Lua-API bridge allows Dict params to be empty Lua (list) tables at
the function-signature level. But not for _nested_ Dicts, because they
are not modeled:
https://github.com/neovim/neovim/blob/fae754073289566051433fae74ec65783f9e7a6a/src/nvim/api/keysets.lua#L184
Some API functions like nvim_cmd check for kObjectTypeDictionary and
don't handle the case of empty Lua tables (treated as "Array").
Solution:
Introduce VALIDATE_T_DICT and use it in places where
kObjectTypeDictionary was being checked directly.

In https://github.com/neovim/neovim/pull/22214, init_default_autocmds
has been turned into a lua function call to nvim_create_augroup and
nvim_create_autocmd.
This introduced a strange regression: a test in vim_spec.lua started
failing with its last_set_chan value switching from 0 to
-9223372036854775808.
It turns out that -9223372036854775808 is the value of LUA_INTERNAL_CALL
and would be inherited as last_set_chan by options set from the command
line due to the WITH_SCRIPT_CONTEXT macro not restoring the channel id
(WITH_SCRIPT_CONTEXT is used by nvim_create_augroup).

Problem:
Validation messages are not consistently formatted.
- Parameter names sometimes are NOT quoted.
- Descriptive names (non-parameters) sometimes ARE quoted.
Solution:
Always quote the `name` value passed to a VALIDATE macro _unless_ the
value has whitespace.
|
| | |
| |
| |
| |
| |
| | |
- VALIDATE() takes a format string
- deduplicate check_string_array
- VALIDATE_RANGE
- validate UI args

Problem:
- API validation involves too much boilerplate.
- API validation errors are not consistently worded.
Solution:
Introduce some macros. Currently these are clumsy, but they at least
help with consistency and avoid some nesting.

Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.

Lua makes (or reuses) an internal copy of strings, so we can safely push
buf pointers onto the stack.

It's confusing to mix vendored dependencies with neovim source code. A
clean separation is simpler to keep track of and simpler to document.

"cfuncs" was only ever used to wrap luarefs. As vim8script is
finished and will not be developed further, support for "cfuncs"
for other usecases are not planned. This abstraction was immediately
broken anyway in order to get luarefs out of userfuncs again.
Even if a new kind of userfunc needs to be invented in the future,
likely just extending the FC_... flag union directy, instead of
invoking unnecessary heap object and c function pointer indirection,
will be a more straightforward design pattern.

`!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false`
is sometimes used to defer exception handling for later (without forgetting the
exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred
to a different call (e.g: when `try_level > 0`).
In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of
`did_throw = false`, but also causes the pending exception to be lost, which
also leaks as `discard_exception()` wasn't used.
It may be possible to fix this by saving/restoring `current_exception`, but
handling all of `did_throw`'s edge cases seems messier. Maybe not worth
diverging over.
This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown
due to Windows missing `man`, but they're lost; skip these tests if `man` isn't
executable.

Make the copy_object() family accept an optional arena. More than
half of the callsites should be refactored to use an arena later
anyway.

- Remove autocmd.h from fileio.h
- Remove normal.h from main.h
- Move bufinfo_T from undo_defs.h to undo.c
|
| |
|
|

This avoids including ex_eval.h in any other header, thus preventing
future circular includes.

use the MAXSIZE_TEMP_ARRAY + ADD_C pattern instead, as exemplified
by the changes in this commit.

** Refactor
Previously most functions used to "get" a mark returned a position,
changed the line number and sometimes changed even the current buffer.
Now functions return a {x}fmark_T making calling context aware whether
the mark is in another buffer without arcane casting. A new function is
provided for switching to the mark buffer and returning a flag style
Enum to convey what happen in the movement. If the cursor changed, line,
columns, if it changed buffer, etc.
The function to get named mark was split into multiple functions.
- mark_get() -> fmark_T
- mark_get_global() -> xfmark_T
- mark_get_local() -> fmark_T
- mark_get_motion() -> fmark_T
- mark_get_visual() -> fmark_T
Functions that manage the changelist and jumplist were also modified to
return mark types.
- get_jumplist -> fmark_T
- get_changelist -> fmark_T
The refactor is also seen mainly on normal.c, where all the mark
movement has been siphoned through one function nv_gomark, while the
other functions handle getting the mark and setting their movement
flags. To handle whether context marks should be left, etc.
** Mark View
While doing the refactor the concept of a mark view was also
implemented:
The view of a mark currently implemented as the number of lines between
the mark position on creation and the window topline. This allows for
moving not only back to the position of a mark but having the window
look similar to when the mark was defined. This is done by carrying and
extra element in the fmark_T struct, which can be extended later to also
restore horizontal shift.
*** User space features
1. There's a new option, jumpoptions+=view enables the mark view restoring
automatically when using the jumplist, changelist, alternate-file and
mark motions. <C-O> <C-I> g; g, <C-^> '[mark] `[mark]
** Limitations
- The view information is not saved in shada.
- Calls to get_mark should copy the value in the pointer since we are
using pos_to_mark() to wrap and provide a homogeneous interfaces. This
was also a limitation in the previous state of things.

This marks the following Vim patches as ported:
vim-patch:8.1.1785: map functionality mixed with character input
Problem: Map functionality mixed with character input.
Solution: Move the map functionality to a separate file. (Yegappan
Lakshmanan, closes vim/vim#4740) Graduate the +localmap feature.
https://github.com/vim/vim/commit/b66bab381c8ba71fd6e92327d1d34c6f8a65f2a7
vim-patch:8.2.3643: header for source file is outdated
Problem: Header for source file is outdated.
Solution: Make the header more accurate. (closes vim/vim#9186)
https://github.com/vim/vim/commit/a3f83feb63eae5464a620ae793c002eb45f7a838
Also cherry-pick a change for <unique> mappings from patch 8.2.0807.

Note for external UIs: Nvim can now emit multiple "redraw" event batches
before a final "flush" event is received. To retain existing behavior,
clients should make sure to update visible state at an explicit "flush"
event, not just the end of a "redraw" batch of event.
* Get rid of copy_object() blizzard in the auto-generated ui_event layer
* Special case "grid_line" by encoding screen state directly to
msgpack events with no intermediate API events.
* Get rid of the arcane notion of referring to the screen as the "shell"
* Array and Dictionary are kvec_t:s, so define them as such.
* Allow kvec_t:s, such as Arrays and Dictionaries, to be allocated with
a predetermined size within an arena.
* Eliminate redundant capacity checking when filling such kvec_t:s
with values.

The size of long varies depending on architecture, in contrast to the
MAXLNUM constant which sets the maximum allowable number of lines to
2^32-1. This discrepancy may lead to hard to detect bugs, for example
https://github.com/neovim/neovim/issues/18454. Setting linenr_T to a
fix maximum size of 2^32-1 will prevent this type of errors in the
future.
Also change the variables `amount` and `amount_after` to be linenr_T
since they're referring to "the line number difference" between two
texts.

Also avoid referring to mappings as "keymaps" in commands and docs.
*map_empty_rhs* *map-empty-rhs*
You can create an empty {rhs} by typing nothing after a single CTRL-V (you
have to type CTRL-V two times). Unfortunately, you cannot do this in a vimrc
file.

feat: user command "preview" (like inccommand)
|

Adds a Lua-only `preview` flag to user commands which allows the command to be incrementally previewed like `:substitute` when 'inccommand' is set.

This avoids generating khash tables at runtime, and is consistent with
