- 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();
- Allow floating windows of width 1. #9846
- For a new floating window the size must be specified. Later on we
might try to calculate a reasonable size by buffer contents
- Remember the configured size of a window, just like its position.
- Make get_config and set_config more consistent. Handle relative='' properly in set_config.
get_config doesn't return keys that don't make sense for a non-floating window.
- Don't use width=0 for non-changed width, just omit the key.
Using a sentinel value in the response-id is ambiguous because the
msgpack-rpc spec allows all values (including zero/max). And clients
control the id, so we can't be sure they won't use the sentinel value.
Instead of a sentinel value, check the message type explicitly.
ref #8850
validate_cursor() is called regularly, but only for the current window.
When changing the buffer for a non-current window, we need to invoke it
in the context of that window.
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.
vim-patch:7.4.1858: Add BLN_NEW to enforce buflist_new creating new buffer
Why?
- Because we can.
- Because the TUI is just another GUI™
- Because it looks kinda nice, and provides useful context like 1 out of 100
times
Complies with "don't pay for what you don't use".
Some crashes for resizing were unfolded, add tests for those.
Initially we will use this for the popupmenu, floating windows will
follow soon
NB: writedelay + compositor is weird, we need more flexible
redraw introspection.
