1. Cannot display chinese/japanese characters (haven't tried other unicodes) probably. 2. How to paste ? 3. unknown input key for "Shift" etc. 4. unknown redraw event for popmenu etc.

[alexlai97]

1. having trouble displaying unicode

As shown above, the left is Gnvim, right is nvim in terminal. Notice that the cursor in both pictures should be on same character but Gnvim seems to have cursor on 12 characters before.

Notice if I put cursor to the end of line, Gnvim's cursor is on whitespace.

And characters from a page (e.g. startify) before was not be cleared

2. how to paste from clipboard? I tried Ctrl+v, Ctrl+Shift+v, but only showing '^'.

3. whenever I press keystroke other than "0-9a-z", e.g., Shift, Alt, Win, F1, Shift and Alt key seems working, but F1-F8 doen't work (help page not showing), stdout shows

4. whenever I call command or it calls deoplete (whenever a window needs to be drawn) command

deoplete

things seems to work but stdout shows

5. snippet not showing where it is from, only showing when I Ctrl+n to it

After Ctrl+n

I am using neosnippet, and it will show [ns] indicating it can be spanned. But in Gnvim, I can trigger the snippet but it is not showing me whether it can be spanned.

6. does it support previewing feature for LanguageClient-neovim other than vim-lsp

Currently it's like this

1. My guess is that this is something to do with double-width characters, but I might be wrong. I have a idea how to fix this; can you give me some piece of text that reproduces the problem you're describing?
2. There isn't any clipboard support built in to gnvim. You'll have to use nvim registers, at least for now.
3. "Failed to turn input...." isn't something you need to worry about. They are there for debugging purposes. I should probably turn those off.
4. I don't understand what the problem here is. Unknown redraw event messages are printed to stdout when gnvim receives a redraw event it doesn't recognize (e.g. aren't implemented nor silenced).
5. That information on the completion menu is (currently) only shown on the selected item (its the menu part of the completion item).
6. The hover support for vim-lsp is implemented by https://github.com/vhakulinen/gnvim-lsp, but similar support for LanguageClient-neovim should be trivial to implement. See :h gnvim-cursor-tooltip and related functions.

Just for additional context, you can use (in normal mode) "+p to paste from the regular clipboard (ctrl+c) and *+p to past from the selection clipboard (text you have previously selected with the mouse)

does it support previewing feature for LanguageClient-neovim other than vim-lsp

I am not sure if by that you mean the gnvim-lsp plugin or the floating window preview that some plugins already implement. If you mean floating window support, it's handled by neovim separately for now, see https://github.com/vhakulinen/gnvim/issues/23. You also need the development version of neovim.

1. My guess is that this is something to do with double-width characters, but I might be wrong. I have a idea how to fix this; can you give me some piece of text that reproduces the problem you're describing?

The string was "可不可以显示长句子？中文、日本語を勉強しています。"

3. "Failed to turn input...." isn't something you need to worry about. They are there for debugging purposes. I should probably turn those off.

But "F1" in terminal nvim will show help page, while in gnvim there is no response. I also have keybindings for F3, F8, neither shows response in gnvim.

4. I don't understand what the problem here is. Unknown redraw event messages are printed to stdout when gnvim receives a redraw event it doesn't recognize (e.g. aren't implemented nor silenced).

When I press shift+semicolon, it will show the a window with ":" in it. At the same time, stdout prints unknown redraw event, which confuses me. But nothing breaks and things work as expected.

5. That information on the completion menu is (currently) only shown on the selected item (its the menu part of the completion item).

Is it possible to toggle to show that information for not selected items ?

@alexlai97 can you try if #36 fixes the issue with text rendering you are experiencing?

[badosu]

@alexlai97 You can remap C-C, C-V on vim:

vnoremap <C-C> "+y
map <C-V>       "+gP
cmap <C-V>      <C-R>+

@alexlai97 can you try if #36 fixes the issue with text rendering you are experiencing?

After I git checkout support-doublewidth-chars; make; sudo make install; gnvim. It panics. Enabling rust_backtrace=1 gives me err.log

[vhakulinen]

Run with cargo run so the binary has debug symbols and the log gives more information. Also, preferably paste the output to the comment or link it to a gist.

4983c99d0cbd74b800679f6248f68d28b02c7197 adds support for function keys. Regarding shift key, it by itself (afaik) doesn't do anything and thus' is not sent to neovim.

Function key works!

Can you try now?

Can you try now?

It seems to work fine! It can display chinese, japanese characters correctly.

Is there any item preventing this issue from being closed?

For 5. I would like to have an option for toggling to show unfocused info (where the completion is from, snippet ? language client protocol ? or just word from dictionary). Now it is only showing info for the focused entry.

For 6. I am not actively trying to find solution to use LanguageClient-neovim with preview option. I believe it is possible to use but it is not that urgent for me. It would be nice to have a plugin for LanguageClient-neovim similar to gnvim-lsp though.

[badosu]

For 6. I use coc.vim and use its preview window with gnvim with no problems (see 'doHover' mapping on the readme)

[vhakulinen]

Opened #41 for the 5th point. Closing this one as other issues mentioned here are solved. For the new 6th point, you can look at the gnvim-lsp's source and :h gnvim-cursor-tooltip on how to use the cursor tooltip to display other content.

It seems that the issue is still present on latest master branch:
