Invisible cursor and strange colors

[damanis]

OS Ubuntu 20.04

Neoray version Neoray version: compiled 51f01a12 nvim version: NVIM v0.8.0-dev+608-g778541067

Problems

• Sometimes a cursor still invisible
• Sometimes strange colors: instead of If return to version 0.1.1 - same problem. Before trying this version, 0.1.1 worked properly.

Steps to reproduce

1. Create file:

   
   TITLE: qweqwe
   END: qweqwe

02-01-2022: text2

01-01-2022: text1

2. Add to some nvim lua init file:

vim.api.nvim_exec([[ au BufNewFile,BufRead *.txt call Detect_jdoc() fun Detect_jdoc() if getline(1) =~? "^TITLE:" || getline(2) =~? "^TITLE:" setlocal filetype=jdoc endif endfun ]], false)

3. Open the created file by Neoray several times.

**Neoray config in init.vim**
lua/settings.lua:

vim.api.nvim_exec([[ if exists('g:neoray') " Now impossible to disable cursor animation by 'NeoraySet CursorAnimTime 0' NeoraySet CursorAnimTime 0.001 NeoraySet ContextMenuOn false NeoraySet WindowSize 100x52 colorscheme uwu set guifont=Go-Mono-Nerd-Font-Complete:h11 endif ]], false)

**Debug output (you can generate starting neoray with --verbose option)**
The is no difference between Neoray_verbose.log in success and fail

Thanks for detailed information. I tried but I couldn't reproduce this. Is this started happening after 51f01a1 ? Also this can be a colorscheme issue. If you updated your plugins, a bug in a plugin may also have caused this.

[damanis]

I didn't see the problem until try 51f01a12. Checked with different colorschemes (for example, github-nvim-theme). Others neovim GUI I use (fvim, neovim-qt, goneovim, nvui) have do problem with same configuration.

[hismailbulut]

So it seems this is not a Neoray issue. This is may be issue of neovim itself or some plugins you are using (I don't know if you are using related plugins for jdoc but it also may cause this) This may remain open until you find out exactly where the issue is coming from.

[damanis]

I checked now with neovim 0.7.2 - same behavior. It doesn't seems nvim issue. I'll update if I find something new.

[damanis]

@hismailbulut It is not about the issue. Now NeoraySet CursorAnimTime 0 does not work. Is there a way to disable cursor animation? Update. I see, it fixed.

[damanis]

Does Neoray saves some internal files (states, configs)?

[hismailbulut]

Does Neoray saves some internal files (states, configs)?

No, Neoray only saves some debugging files (cpu and heap profile, crash log and verbose log) Neoray never saves any config or never changes your any file in your system

[damanis]

@hismailbulut Do you use (during development) some debug options of GLFW? I still can't catch the problem with cursor.

[hismailbulut]

There are some ways you can debug this behavior Please do every step

Debug from Neoray

1. First build neoray with debug tag, just run make build in the workspace and it will generate neoray_debug in bin folder
2. Open debug build, reproduce issue and middle click one of the cell has issue. This will print cell info to terminal
3. Copy cell info and put it here so I can look at it

Debug from neovim

1. Move cursor to the same cell you middle clicked
2. Run command :echo synIDattr(synIDtrans(synID(line("."), col("."), 1)), "fg") and put output here
3. Run command :echo synIDattr(synIDtrans(synID(line("."), col("."), 1)), "bg") and put output here
4. Run command :echo synIDattr(synIDtrans(synID(line("."), col("."), 1)), "name") and put output here
5. Run command :echo synIDattr(synID(line("."), col("."), 1), "name") and put output here

Additional steps

1. Open Neoray with command ./neoray_debug -u NORC and try to reproduce
2. Open Neoray with command ./neoray_debug --noplugin and try to reproduce

Commands from section 'Debug from neovim' did not print anything.

[hismailbulut]

Does the issue happens when you run with --noplugin? And those commands has to echo the attributes in neovim command line. Try :messages after commands

[damanis]

The issue happens both for '--noplugin' and '-u NORC' I didn't success with 'Debug from neovim', :messages didn't help too.

[hismailbulut]

Others neovim GUI I use (fvim, neovim-qt, goneovim, nvui) have do problem with same configuration.

Did you mean "no" here

Can you zip and upload a copy of your entire vim config and the file you are working on excluding your sensitive information?

[damanis]

Did you mean "no" here

Sure

[hismailbulut]

Sure

So I'm sorry because I misunderstood you, this is Neoray issue

[damanis]

I just try to open ~/.bashrc. 50% it as Ubuntu default. I tried find problem in config files - results unstable. Continue investigate configs. Debug output didn't help?

[hismailbulut]

Debug output didn't help?

They only helpful together with outputs of commands in Debug from neovim

[hismailbulut]

I can't reproduce with minimal configuration

au BufNewFile,BufRead *.txt call Detect_jdoc()

fun Detect_jdoc()
    echomsg "Detecting jdoc"
    if getline(1) =~? "^TITLE:" || getline(2) =~? "^TITLE:"
        echomsg "jdoc detected"
        setlocal filetype=jdoc
    endif
endfun

if exists('g:neoray')
    " Now impossible to disable cursor animation by 'NeoraySet CursorAnimTime 0'
    " NeoraySet CursorAnimTime 0.001
    NeoraySet ContextMenuOn false
    NeoraySet WindowSize 100x52
    " colorscheme uwu
    " set guifont=Go-Mono-Nerd-Font-Complete:h11
endif

with start command: neoray -u issue35.vim --noplugin

result:

[damanis]

I found why 'echo' commands you requested are not shown - their output is empty. Probably, some error in the commands.

[damanis]

@hismailbulut Today I compiled source with last your changes (last commit is 0f9133ef) and currently I don't see the invisible cursor problem. I will update you if it returns.
