Problem:
vim.json.encode escapes every slash in string values (for example in
file paths), and is not optional. Use-case is for preventing HTML
injections (eg. injecting `</script>` closing tag); in the context of
Nvim this is rarely useful.
Solution:
- Add a `escape_slash` flag to `vim.json.encode`.
- Defaults to `false`. (This is a "breaking" change, but more like
a bug fix.)
Problem:
`vim.loader.disable` does not conform to `:help dev-name-common` and
`:help dev-patterns`.
Solution:
- Add `enable` parameter to `vim.loader.enable`
- Remove `vim.loader.disable`
- Note the change in `:help news-breaking-dev` (HEAD changes).
- This is not a breaking change (except to "HEAD") because
`vim.loader` is marked "experimental".

Problem: No longer able to show prompt messages with vim.ui_attach().
Solution: Do not execute callback in fast context for prompt message
kinds. These events must be safe to show the incoming message
so the event itself serves to indicate that the message
should be shown immediately.
Problem: Lua callbacks for "msg_show" events with vim.ui_attach() are
executed when it is not safe.
Solution: Disallow non-fast API calls for "msg_show" event callbacks.
Automatically detach callback after excessive errors.
Make sure fast APIs do not modify Nvim state.
PROBLEM:
There are several limitations to vim.str_byteindex, vim.str_utfindex:
1. They throw given out-of-range indexes. An invalid (often user/lsp-provided)
index doesn't feel exceptional and should be handled by the caller.
`:help dev-error-patterns` suggests that `retval, errmsg` is the preferred
way to handle this kind of failure.
2. They cannot accept an encoding. So LSP needs wrapper functions. #25272
3. The current signatures are not extensible.
* Calling: The function currently uses a fairly opaque boolean value to
indicate to identify the encoding.
* Returns: The fact it can throw requires wrapping in pcall.
4. The current name doesn't follow suggestions in `:h dev-naming` and I think
`get` would be suitable.
SOLUTION:
- Because these are performance-sensitive, don't introduce `opts`.
- Introduce an "overload" that accepts `encoding:string` and
`strict_indexing:bool` params.
```lua
local col = vim.str_utfindex(line, encoding, [index, [no_out_of_range]])
```
Support the old versions by dispatching on the type of argument 2, and
deprecate that form.
```lua
vim.str_utfindex(line) -- (utf-32 length, utf-16 length), deprecated
vim.str_utfindex(line, index) -- (utf-32 index, utf-16 index), deprecated
vim.str_utfindex(line, 'utf-16') -- utf-16 length
vim.str_utfindex(line, 'utf-16', index) -- utf-16 index
vim.str_utfindex(line, 'utf-16', math.huge) -- error: index out of range
vim.str_utfindex(line, 'utf-16', math.huge, false) -- utf-16 length
```
Problem:
`vim.validate()` takes two forms when it only needs one.
Solution:
- Teach the fast form all the features of the spec form.
- Deprecate the spec form.
- General optimizations for both forms.
- Add a `message` argument which can be used alongside or in place
of the `optional` argument.
Problem:
- `vim.highlight` module does not follow `:help dev-name-common`, which
documents the name for "highlight" as "hl".
- Shorter names are usually preferred.
Solution:
Rename `vim.highlight` to `vim.hl`.
This is not a breaking change until 2.0 (or maybe never).
An implication of this current approach is that `NVIM_API_LEVEL` should be
bumped when a new Lua function is added.
TODO(future): add a lint check which requires `@since` on all new functions.
ref #25416
Some composite/compound types even as basic as `(string|number)[]` are
not currently supported by the luacats LPEG grammar used by gen_vimdoc.
It would be parsed & rendered as just `string|number`.
Changeset adds better support for these types.
Problem:
Linematch used to use strchr to navigate a string, however strchr does
not supoprt embedded NULs.
Solution:
Use `mmfile_t` instead of `char *` in linematch and introduce `strnchr()`.
Also remove heap allocations from `matching_char_iwhite()`
Fixes: #30505
Problem:
User cannot configure the tool used by `vim.ui.open` (or `gx`). With
netrw this was supported by `g:netrw_browsex_viewer`.
Solution:
Introduce `opts.cmd`. Users that want to set this globally can
monkey-patch `vim.ui.open` in the same way described at `:help vim.paste()`.

Problem: vim.tbl_deep_extend had an undocumented feature where arrays
(integer-indexed tables) were not merged but compared literally (used
for merging default and user config, where one list should overwrite the
other completely). Turns out this behavior was relied on in quite a
number of plugins (even though it wasn't a robust solution even for that
use case, since lists of tables (e.g., plugin specs) can be array-like
as well).
Solution: Revert the removal of this special feature. Check for
list-like (contiguous integer indices) instead, as this is closer to the
intent. Document this behavior.
Problem: Plugin authors and distribution packagers are confused about
the role of LuaJIT vs. PUC Lua.
Solution: Clarify that LuaJIT is preferred but not required (extensions
should not be assumed but checked for) and that vanilla Lua 5.1 should
be used without language extensions such as `goto`.
This patch replaces fswatch with inotifywait from inotify-toools:
https://github.com/inotify-tools/inotify-tools
fswatch takes ~1min to set up recursively for the Samba source code
directory. inotifywait needs less than a second to do the same thing.
https://github.com/emcrisostomo/fswatch/issues/321
Also it fswatch seems to be unmaintained in the meantime.

For many small/simple functions (like those found in shared.lua), the
runtime of vim.validate can far exceed the runtime of the function
itself. Add an "overload" to vim.validate that uses a simple assertion
pattern, rather than parsing a full "validation spec".
`vim.health` is not a "plugin" but part of our Lua API and the
documentation should reflect that. This also helps make the
documentation maintenance easier as it is now generated.
The optimizations that vim.iter uses for array-like tables don't require
that the source table has no holes. The only thing that needs to change
is the determination if a table is "list-like": rather than requiring
consecutive, integer keys, we can simply test for (positive) integer
keys only, and remove any holes in the original array when we make a
copy for the iterator.
