PROBLEM:
Currently `:echoerr` prints multi-line strings in a single line
as `:echom` does (Note: `:echon` can print multi-line strings well).
This makes stacktrace printed via echoerr difficult to read.
Example code:
try
lua error("lua stacktrace")
catch
echoerr v:exception
endtry
Output:
Error detected while processing a.vim[5]..a.vim:
line 4:
Vim(lua):E5108: Error executing lua [string ":lua"]:1: lua stacktrace^@stack traceback:^@^I[C]: in function 'error'^@^I[string ":lua"]:1: in main chunk
SOLUTION:
Allow echoerr to print multiline messages (e.g., lua exceptions),
because this command is usually used to print stacktraces.
Output after the fix:
Error detected while processing a.vim[5]..a.vim:
line 4:
Vim(lua):E5108: Error executing lua [string ":lua"]:1: lua stacktrace
stack traceback:
[C]: in function 'error'

Problem: Vim9: in script cannot set item in uninitialized list.

Problem: The style guide states that all switch statements that are not conditional on an enum must have a `default` case, but does not give any explicit guideline for switch statements that are conditional on enums. As a result, a `default` case is added in many enum switch statements, even when the switch statement is exhaustive. This is not ideal because it removes the ability to have compiler errors to easily detect unchanged switch statements when a new possible value for an enum is added.
Solution: Add explicit guidelines for switch statements that are conditional on an enum, clarifying that a `default` case is not necessary if the switch statement is exhaustive. Also refactor pre-existing code with unnecessary `default` cases.
This adds the checks in https://neovim.io/doc/reports/clang/ when using
clang-tidy. The strategy is to enable all clang-analyzer checks, and
disable only the checks for the warnings that exist currently. This
allows us to eliminate each warning type without blocking ongoing work,
but also without adding bugs for already eliminated warnings.
The plan is to eventually eliminate https://neovim.io/doc/reports/clang/
by completely integrating it into the clang-tidy check.
Also add make and cmake targets `clang-analyzer` to run this check.
long is 32 bits on windows, while it is 64 bits on other architectures.
This makes the type suboptimal for a codebase meant to be
cross-platform. Replace it with more appropriate integer types.

msg_puts_display was more complex than necessary in nvim, as in
nvim, it no longer talks directly with a terminal.
In particular we don't need to scroll the grid before emiting the last
char. The TUI already takes care of things like that, for terminals
where it matters.

This involves two redesigns of the map.c implementations:
1. Change of macro style and code organization
The old khash.h and map.c implementation used huge #define blocks with a
lot of backslash line continuations.
This instead uses the "implementation file" .c.h pattern. Such a file is
meant to be included multiple times, with different macros set prior to
inclusion as parameters. we already use this pattern e.g. for
eval/typval_encode.c.h to implement different typval encoders reusing a
similar structure.
We can structure this code into two parts. one that only depends on key
type and is enough to implement sets, and one which depends on both key
and value to implement maps (as a wrapper around sets, with an added
value[] array)
2. Separate the main hash buckets from the key / value arrays
Change the hack buckets to only contain an index into separate key /
value arrays
This is a common pattern in modern, state of the art hashmap
implementations. Even though this leads to one more allocated array, it
is this often is a net reduction of memory consumption. Consider
key+value consuming at least 12 bytes per pair. On average, we will have
twice as many buckets per item.
Thus old implementation:
2*12 = 24 bytes per item
New implementation
1*12 + 2*4 = 20 bytes per item
And the difference gets bigger with larger items.
One might think we have pulled a fast one here, as wouldn't the average size of
the new key/value arrays be 1.5 slots per items due to amortized grows?
But remember, these arrays are fully dense, and thus the accessed memory,
measured in _cache lines_, the unit which actually matters, will be the
fully used memory but just rounded up to the nearest cache line
boundary.
This has some other interesting properties, such as an insert-only
set/map will be fully ordered by insert only. Preserving this ordering
in face of deletions is more tricky tho. As we currently don't use
ordered maps, the "delete" operation maintains compactness of the item
arrays in the simplest way by breaking the ordering. It would be
possible to implement an order-preserving delete although at some cost,
like allowing the items array to become non-dense until the next rehash.
Finally, in face of these two major changes, all code used in khash.h
has been integrated into map.c and friends. Given the heavy edits it
makes no sense to "layer" the code into a vendored and a wrapper part.
Rather, the layered cake follows the specialization depth: code shared
for all maps, code specialized to a key type (and its equivalence
relation), and finally code specialized to value+key type.
ml_get_buf() takes a third parameters to indicate whether the
caller wants to mutate the memline data in place. However
the vast majority of the call sites is using this function
just to specify a buffer but without any mutation. This makes
it harder to grep for the places which actually perform mutation.
Solution: Remove the bool param from ml_get_buf(). it now works
like ml_get() except for a non-current buffer. Add a new
ml_get_buf_mut() function for the mutating use-case, which can
be grepped along with the other ml_replace() etc functions which
can modify the memline.
Problem: Fix regression in {func} argument of reduce()
Solution: pass function name as string again
Before patch 9.0.0548, passing a string as {func} argument of reduce()
is treated as a function name, but after patch 9.0.0548 it is treated as
an expression instead, which is useless as reduce() doesn't set any v:
variables. This PR restores the behavior of {func} before that patch.
Also correct an emsg() call, as e_string_list_or_blob_required doesn't
contain format specifiers.

Removes the `getoption_T` struct and also introduces the `OptVal` struct
to unify the methods of getting/setting different option value types.
This is the first of many PRs to reduce code duplication in the Vim
option code as well as to make options easier to maintain. It also
increases the flexibility and extensibility of options. Which opens the
door for things like Array and Dictionary options.
Problem: Cursor ends up below the window after a put.

Adds new API helper macros `CSTR_AS_OBJ()`, `STATIC_CSTR_AS_OBJ()`, and `STATIC_CSTR_TO_OBJ()`, which cleans up a lot of the current code. These macros will also be used extensively in the upcoming option refactor PRs because then API Objects will be used to get/set options. This PR also modifies pre-existing code to use old API helper macros like `CSTR_TO_OBJ()` to make them cleaner.
This reduces the total number of khash_t instantiations from 22 to 8.
Make the khash internal functions take the size of values as a runtime
parameter. This is abstracted with typesafe Map containers which
are still specialized for both key, value type.
Introduce `Set(key)` type for when there is no value.
Refactor shada.c to use Map/Set instead of khash directly.
This requires `map_ref` operation to be more flexible.
Return pointers to both key and value, plus an indicator for new_item.
As a bonus, `map_key` is now redundant.
Instead of Map(cstr_t, FileMarks), use a pointer map as the FileMarks struct is
humongous.
Make `event_strings` actually work like an intern pool instead of wtf it
was doing before.
Problem: Various comment and indent flaws.
Solution: Improve comments and indenting.
