Cannot parse which-key mappings

[sjclayton]

I have my which-key mappings table setup like the Primary example in the which-key README

Similar to this...

wk.register({
  f = {
    name = "file", -- optional group name
    f = { "<cmd>Telescope find_files<cr>", "Find File" }, -- create a binding with label
    r = { "<cmd>Telescope oldfiles<cr>", "Open Recent File", noremap=false, buffer = 123 }, -- additional options for creating the keymap
    n = { "New File" }, -- just a label. don't create any mapping
    e = "Edit File", -- same as above
    ["1"] = "which_key_ignore",  -- special label to hide it in the popup
    b = { function() print("bar") end, "Foobar" } -- you can also pass functions!
  },
}, { prefix = "<leader>" })

Using prefix at the end... and I get an error when I run HawtkeysAll that says "Error parsing which-key table"

I have this as part of my config opts for hawtkeys

-- If you use whichkey.register with an alias eg wk.register
        ["wk.register"] = {
            method = "which_key",
        },

Can you confirm versions of hawtkeys, whichkey and neovim pls @sjclayton

Neovim is latest nightly hawtkeys is ^HEAD which-key is ^HEAD

Neovim is latest nightly hawtkeys is ^HEAD which-key is ^HEAD

I think this is a format in whichkey I didn't consider

Let me recreate this in a test

This is the format we test for

The way shown in the primary example in the documentation I believe is the default way in which most configs I've seen have been implemented, so it might be good to add it, so things don't break if someone followed the which-key docs. :100:

Fully agree with you

I would like to support all methods

[tris203]

@sjclayton please could you try with the branch I have created for this

issue81

issue81

No go, still giving the same error when I try on that branch.

[tris203]

Are your dotfiles public? I might need to see the example

As we pass all of the examples in the readme for whichkey on that branch

[sjclayton]

It would appear the which-key mappings are being populated in the list now, but the error is still being thrown even so...

Question, can your plugin be effectively lazy loaded or loaded after which-key and still work?

Also you can check here -- keymap config

[tris203]

I have also just pushed another commit to that branch that may give a more meaningful error

[sjclayton]

@tris203 I get the which-key table back in the error now

The above is the complete output, nothing removed or added.

It would appear the which-key mappings are being populated in the list now, but the error is still being thrown even so...

Question, can your plugin be effectively lazy loaded or loaded after which-key and still work?

Also you can check here -- keymap config

Yes. You can lazy load on cmd. The parsing is all done on UI open

So you can re-open as you edit the config and it should update in real time

Do you get a different message with the latest commit I just pushed?

[tris203]

That's really helpful

I'm headed to bed now. But will take another look tomorrow and hopefully get this sorted for you

[sjclayton]

@tris203 Just noticed something else... like I said the which-key mapping are showing up now, even though the error is still getting thrown.

But in the list they are being labeled as being Vim Defaults

I'm not sure if this is intended behavior, because I see that the Lazy key mappings are labeled as being configured from Lazy.

Just thought I'd mention that.

[tris203]

I see what the problem is i think. It is because of the subset of icons.ui.*

we evaluate the string to turn it back into a table, but that fails I assume due to the assigned var.

let me think about how we are best to handle this...

[sjclayton]

@tris203 Is there no way of filtering out the name field completely? as technically in and of itself it isn't actually part of a mapping and should be ignored anyways..

So if you get a table with an object that contains that field you return the same table/object with the field stripped?

[tris203]

yes @sjclayton, but the problem isn't just limited to the name field, it could be used for the function definition itself.

as it is in the test case I've written in pr #84

for which key mapping is 1) Extract everything inside the function call as a string 2) return it through loadstring() to make it into a table 3) pass it through the actual whichkey mapping parser (this allows us to support everything which-key supports with little overhead)

We fall over at step 2, in this case, as the string can't be return'd into a lua table as variables inside the string are undefined.

You could rewrite each var to be standalone eg instead of icons.ui.* you would use require('icons).ui.* but that is unreasonable and one of the goals of this project is to require 0 alterations to your config to be compatible.

@sjclayton can you retry with the issue81 branch?

[sjclayton]

@sjclayton can you retry with the issue81 branch?

Just updated, still a no go... same error.

[tris203]

@sjclayton can you retry with the issue81 branch?

Just updated, still a no go... same error.

I'm narrowing in on the issue, it works for variables that are out of scope and included in the function But it returns a table, and you concatenate onto them as strings.

Thanks for the issue, this one is definately a brain tickler

[sjclayton]

@tris203 Glad to see it's makin' ya think 😉
