Upcoming Vim 8.2 release

[Bram Moolenaar]

It appears the number of bug reports is getting lower. I have included
many pending pull requests. I think we are getting closer to a release.

If you have any runtime updates, please send them now!

I'm also wondering: what is your favorite improvement since Vim 8.1?

I saw the latest version8.txt.
In the "Vim script improvements" section, the ".." operator is not described
explicitly. (It is described as a part of `:scriptversion`.)
How about adding it explicitly?

We already had VIMDLL, but it was basically removed and re-implemented.

I rather not change it so short before a release.

I updated the text to also mention things that were removed and
graduated:


Vim script improvements *new-vimscript-8.2*
-----------------------

Functions can now be called in a chain, using "->": >

mylist->filter(filterexpr)->map(mapexpr)->sort()->join()

The new `:eval` command can be used if the chain has no result.

The `:scriptversion` command was added to allow for changes that are not

backwards compatible. E.g. to only use ".." for string concatenation, so that
"." can be used to access a dictionary member consistently.

`:const` was added to allow for declaring a variable that cannot change: >
const TIMER_DELAY = 400

A heredoc-style assignment was added to easily assign a list of lines to a
variable without quoting or line continuation: >
let lines =<< trim END
line one
line two
END

The |Blob| type was added. This makes it easy to deal with binary data.

The /= and %= assignment operators were added.

A Dictionary can be defined with #{} where the keys are used literally. This
avoids having to use quotes: >
let options = #{width: 30, height: 24}


Other improvements *new-other-8.2*
------------------

- When 'incsearch' is set it also applies to `:substitute`.
- |modifyOtherKeys| was added to allow mapping more key combinations.
- ConPTY support was added for Windows 10, supports full color in the terminal.
- The windows installer supports translations, silent install and looks
better.


Changed *changed-8.2*
-------

The xdiff library was included to avoid the need for an external diff program
and to make updating diffs much faster.

The code is using a few more modern C features, such as // comments.

Support for old compilers has been dropped: Borland C++, MSVC 2008.

Hangul input support was removed, it actually didn't work.

The FEAT_TAG_OLDSTATIC code was removed, it slowed down tag searches.
The FEAT_TAG_ANYWHITE code was removed, is was not enabled in any build.
The UNICODE16 code was removed, it was not useful.
Workshop support was removed, nobody was using it.
The Aap build files were removed, they were outdated.
Farsi support was removed, it was outdated and unused.

VIMDLL was re-implemented, this shares the common parts between vim and gvim
to reduce the total install size.

The following features are now included in all versions: |+mbyte|,
|+virtualedit|, |+vreplace|, |+localmap|, |+cmdline_hist|, |+cmdline_compl|,
|+insert_expand|, |+modify_fname|, |+comments|

We already had VIMDLL, but it was basically removed and re-implemented.

Ah, I completely forgot about the old VIMDLL implementation. ;-)

The old one just created a DLL for gvim.exe and didn't share the code with vim.exe.

I wonder if the original author intended to share the code with gvim.exe and vim.exe (in a future).

OK, enabling VIMDLL by default is a next task for Vim 8.3 (or later).

If we enable it, we also need to update the nsis script.

I consider preparing that.

Looks good.

It was changed in June. I'll include this change.

popup windows :) I guess I'm a little biased, but I think this is a great improvement, and the API is really nice to use.

I'm glad you like it, it was quite a lot of work to implement it all.

If someone has a nice screenshot, please show us. I would like to
include some in the 8.2 announcement.

I'm also really enjoying the popups. I have a screencast here, but it demonstrates a problem rather than acts as a showcase I think:

https://asciinema.org/a/ARcxLcTKZepZfnBTsBjFqv88y

The flickering of both the popupmenu and the 'info' popup are quite extreme. Admittedly this example is also extreme in the sense that there are many settings and plugins in use here, including text properties being used to semantically highlight the buffer. But my efforts to reduce the issue to any one plugin or option have failed - there is always _some_ flickering in a completion menu with 'info' and `completeopt+=popup`, and the more highlights and text_properties in the buffer, the more obvious the flickering becomes.

Does the popupmenu have to be destroyed and recreated as the selection changes? Or can redrawing perhaps be disabled during this period?

It should not flicker that much. Especially now that a mask is used to
only redraw what is needed.

Perhaps your code somehow marks the menu in a way it's destroyed and
recreated? Can you make a simplified example (with dummy data) to
illustrate the problem? If you have an async way of updating, you can
use a timer to simulate that.

Yes that's the tricky bit, it doesn't flicker nearly that much in a
minimal example, so it's hard to demonstrate. But here is a minimal
example and there _is_ flickering, particularly when moving from
completion items with no 'info' to items _with_ 'info':

https://asciinema.org/a/qAVyBR43LeuGgM2jenE4Mb3VS

The example here is the following, where the completion menu is
triggered with `<C-x><C-u>`:

```vim

func DummyComplete(findstart, base)
if a:findstart
return 0
else
let info = range(100)->map({_ -> 'abcde'})->join()
let noinfo_items = range(5)->map({i -> #{ word: 'word_'..(i+5) }})
let info_items = range(5, 10)->map({i -> #{ word: 'word_'..i, info: info }})
return noinfo_items + info_items
endif
endfunc


set completeopt+=popup
setlocal completefunc=DummyComplete
```

Regards, Nick

[Bram Moolenaar]

Thanks for the example, I can see the problem.

When the info popup is used redrawing is done differently and a flag
isn't set that avoids drawing over the popup menu. Let me set that flag
check for side effects.

BTW: still looking for nice screenshots to use in the Vim 8.2
announcement.

Patch 8.1.2415 is a huge improvement. With ordinary 'info' there is no
longer any flickering of the menu, or the "preview" popup.

However, replacing the contents of the preview popup still cause the
completion menu to flicker (less than before though):
