90% of time no autocompletion

[idchlife]

Describe the bug First of all big thank you for this plugin! Though it doesn't work as expected yet - possibility to code in F# in vim is fantastic!

90% of time plugin does not work. No errors. No autocompletion. No type hints etc. I don't understand how it worked 2 times to be honest. Maybe there are logs somewhere, where I can check what's happening?

To Reproduce Steps to reproduce the behaviour:

1. Create new project with these:

Files contents

```xml netcoreapp3.0 false ``` ```fs module GradeSchool type School = Map let empty: School = School() let add (student: string) (grade: int) (school: School): School = Map.add grade student school //let compare let roster (school: School): string list = school |> Map.iter |> let grade (number: int) (school: School): string list = school[number] ```

2. Open file with vim GradeSchool.fs
3. See message down in vim that workspace loaded successfully
4. See that there is no features of plugin. No autocomplete, errors, warnings, types etc

Expected behaviour To work as it worked for 2 times

This might be related to https://github.com/ionide/Ionide-vim/issues/22: try downgrading LC-neovim to 0.1.155 or calling :FSharpLoadWorkspaceAuto manuually.

Running dotnet restore and/or dotnet build tends to solve this kind of problem too.

[idchlife]

@cannorin it seems there is no tag for version you mentioned:

I tried loading and reloading workspace - no luck.

Tried dotnet restore - no luck

I remember that the last time plugin worked I did :FSharpUpdateFSAC (mayyybe it mattered?) but now when I try to repeat this step - nothing useful happens.

[cannorin]

0.1.155 is here: https://github.com/autozimu/LanguageClient-neovim/releases/tag/0.1.155

FSAC tends to break for no reason. From my experience removing bin and obj and then dotnet build sometimes fixes the issue. If you can provide the project you are working with I can try with it myself.

[cannorin]

For the tag, I think you can just write it as

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'tag': '0.1.155',
    \ 'do': 'bash install.sh',
    \ }

[idchlife]

@cannorin here is project acrhive: https://ufile.io/0x211sl3

[cannorin]

Thanks, I'll check it tomorrow~

[idchlife]

@cannorin sorry to bother you. Did you have time to check bug?

[cannorin]

@idchlife Sorry, no time 😭 Will do on Sunday.

[cannorin]

Reproduced on my environment (Debian, neovim, latest FSAC). Ionide-VSCode loads correctly so this should be an issue with Ionide-vim.

[cannorin]

It is very weird but Ionide-vim starts working if you open the project with Ionide-VSCode. I'm investigating why...

[cannorin]

It turns out obj/fsac.cache matters but I don't know why it is not created on Ionide-vim in this case (it gets created when you open a fresh project created with dotnet new).

[idchlife]

@cannorin thanks for investigating!

is there way to create this fsac.cache via cli or something? ionide-vscode does not actually work on my machine at all unfortunately :( Cannot create it

[cannorin]

@idchlife I'm investigating but I don't know at the moment... The best workaround is to create a new project with dotnet new, open the created project with Ionide-vim, get the completion working, and then paste the existing codes.

[cannorin]

Opening a fresh project with Ionide-vim should create obj/fsac.cache correctly. If it doesn't please let me know...

[OmanF]

Attached gif shows indeed no autocomplete. (It's 1:30 minutes, I took my time). As can be seen in the "mini-buffer", FSAC knows the different built-in functions and displays their signature as I hover over them. Also, I get all the compiler errors and warnings.

But no autocomplete.

(Some metadata: NeoVim 0.4.4; Linux Debian Sid; Installed following the instructions on the README (paying attention to select the correct tag; Started a project from CLI via dotnet new console...)

[cannorin]

@OmanF Did not reproduce on Neovim 0.3.4, Debian stable. Did you install deoplete or vim-mucomplete along with LanguageClient-neovim?

[OmanF]

I didn't install any other LSP plugin other than LC-neovim.

Having said that, I've transitioned to a RebornOS-based work machine and COC (also installed .Net Core using Pacman, as opposed to the Debian machine, where I manually extracted the SDK to a folder on the PATH). Lots of changes that now give me VSCode-quality F# editing experience in NeoVim. So, for me, I no longer have the issue since I moved away from the offending config.

But others still seem to...

Letting you decide if this can/should be closed.

[cannorin]

@OmanF I mean, if you do not install the auto-completion plugin like deoplete or vim-mucomplete, you will get poor auto-completion. I thought it might be the case you forgot to install one.

Sorry to hear you gave up using this plugin. I also understand how the configuration things irritated you. But let me say that I or this project have no intention to offend you and I seriously need your help and, say, you could have helped me. I have to take classes at univ. I have to do a part-time job to keep on living. I sometimes want to take a rest and play games. I also have many other OSS projects to work on. I have many responsibilities, and cannot do OSS stuff like 24/7. Your help is, or was, needed.

[OmanF]

Hi @cannorin. First off, no offense taken. I whole-heartedly appreciate all you folks doing OSS are doing. I try my hand at PR-ing when I feel up to the task, but usually, I'm a consumer. Never do I think you, an OSS maintainer, owe me anything!

That out of the way, the move away was not due to Ionide-Vim... I wanted to try a rolling-release distro, and once there, COC was just what "the internet" suggested, so that's what I went for.

That out of the way, I will, today, tomorrow, in the very near future, play around with my init.vim file. I'll re-install Ionide-Vim and an auto-completion framework and see if that is comparable to COC. No worries. I'll let you know my findings when I have them. (That would be really a dumb-moment for me if it turns out all it took was an auto-completing framework...)

[OmanF]

'K, tried playing around and here's what I found: (Preface: all plugin changing was done by commenting out the plugin(s) on init.vim, uncommenting the other plugin(s), running vim-plug's install command, run vim-plug's clean command to remove the "obsolete" plugins, quit Neovim all together, starting a fresh instance of Neovim. The test F# file is Program.fs created by starting a new console application: dontet new console -lang "F#").

• Using COC "just works": auto-completion, tooltips (on hover), linting.
• Using LanguageClient-neovim+Ionide-vim+deoplete still doesn't give autocomplete. Same behavior as the initial GIF posted.
• Using both COC and the combination of the three plugins... oddly enough NOTHING works: no completion, no tooltips, no linting. As if COC and Ionide-vim interrupt each other (my imagery, I have no idea what really happens in the back-end).

All these are on the new config (I tossed the Debian VM and no longer has access to that specific one).

If there are other tests/ideas you need to me to test, let me know and I'll do my best.

[cannorin]

@OmanF Thanks 😍 Can you post the version of neovim and the init.vim you are using right now? Then I can create an chroot environment to experiment with.

@OmanF I've been doing some experiments and figured out deoplete.nvim is not working in your setup for some reason.

I couldn't figure out why but the other plugins you installed might be causing the issue.

Here is a minimal init.vim that successfully triggers auto-completion.

call plug#begin(expand('$VIMCONFIG/data/plugged'))

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'tag': '0.1.155',
    \ 'do': 'bash install.sh',
    \ }
Plug 'junegunn/fzf'

Plug 'ionide/Ionide-vim', {
    \ 'do':  'make fsautocomplete',
    \}

Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }

call plug#end()

let g:deoplete#enable_at_startup = 1

[cannorin]

@OmanF I think I figured out why. You didn't set let g:deoplete#enable_at_startup = 1 :wink:

[OmanF]

In the attached zip file there are two screen captures, one with Coc (and ALE, though the latter is not strictly necessary), the second with the combination of plugins.

As before, I commented out the plugin(s) I didn't want to test, uncommented those that I did want to use, ran vim-plug's install command to install new plugins, followed by an update to make sure they're up-to-date, quit Neovim then start a new session. The test file is, again, the basic Program.fs of the simplest console app by dotnet.

Each video shows my config, proving which plugin(s) are disabled, which are active, and that all are up to date.

As you can see, the Coc (and ALE) combination works. The other doesn't. It's even worse than the Debian version - now I don't even get compiler errors on obvious mistakes (a "hanging" . after an open expression... that doesn't get worse than that. Also, no warning about unused declaration).

As before, let me know if you need anything else...

trying_autocompletion.tar.gz

[OmanF]

I suspect you are right, that other plugin(s) are clashing with Ionide-vim, or the underlying LSP connector. I just tried the minimal setup you suggested, and, right as rain, it worked great!

Now, figuring out which other plugin(s) is clashing, and if it's indeed a mix of several plugins...

I'm going to leave it at that that we confirmed that the problem is not with Ionide-vim, but a clash of plugins. (I'll continue using my newer config, but at least we now proved this issue can be closed since the problem is not `Ionide-vim).

[OmanF]

Looked at you snippet again, saw that there's a line going 'tag': '0.1.155'... added it to my config, the loaded one, made sure to, as always, disable Coc and ALE. And vim-polyglot!

I guess you see where this is going... works like a charm. I was to blame all along for not copying the installation instruction to the letter. The tag parameter is mandatory!

Also, verified, Coc and Ionide-vim do not play nice together. Choose one, and if you need Coc for other languages... well, life's about tough choices.

Ok, can put this ticket to rest, finally. The issue is not in Ionide-vim, you need the tag parameter, and it doesn't play nice with other LSP providers.

[cannorin]

@OmanF I'm glad it finally worked for you! Yes we are having a problem with LanguageClient-neovim (see #22) and that tag is mandatory for now. Since it is apparently not going to be addressed by its owner, I'm thinking to migrate to something else such as ALE, vim-lsp, or Coc.

[cannorin]

@idchlife Do you still have a problem with this? If not I like to close this issue 🙂

[OmanF]

Moving to either ALE or Coc will be a lot of work for you, I suspect, but they are better known, the most known LSP providers in the Vim-sphere I'd reckon, so if done, would be a boost to both those plugins and to Ionide-vim (no one likes installing more and more plugins, especially ones that may conflict with existing ones).

That said, as I found out, unless my testing method was completely off, at the moment, and probably due to its reliance on LanguageClient-neovim, Ionide-vim is not compatible with Coc, actually clashing.

At any rate, thank you for bringing Ionide to Vim-sphere!
