`to_snake_case` is not working?

[yutkat]

I set up the following mapping. nmap gas <Cmd>lua require('textcase').current_word('to_snake_case')<CR>

error occurs

E5108: Error executing lua ...packer/opt/text-case.nvim/lua/textcase/plugin/plugin.lua:183: attempt to index local 'method' (a nil value)
stack traceback:

I haven't explored custom mapping. Can you try using the regular setup? It is to call

require("text case").setup()

There is an example in the readme using Packer. I should probably add examples using other package managers

My guess is the setup method is not registering the methods. If that's the case, once they are registered, I think custom mappings should work out of the box. But the setup itself also initializes mappings with ga as prefix, therefore there is no need to add them by yourself

[yutkat]

I tried to add the gas (snake case) myself because the wiki mentioned it but did not seem to provide the mapping.

Good catch. I added a note in the string case functions page. Let me know if it still fails after calling the setup method (even let me know if it works!)

By the way, I can still make a fix out of this issue. I can change the module so that it register the methods without calling the setup function. And the setup function would be only for registering the keybindings

I still can't find the command to_snake_case in my environment...

Hi!

Calling .setup() is not anymore a requirement. setup sets keybinding by default. But if you want to add custom key mappings then setup isn't enforced anymore

When you say. you can't find the command. What does it mean?

Is it using Telescope? If that's the case, just merged a PR providing better description It requires calling setup()

Is it calling directly the functions? They are under the api namespace. By the way, it was broken but the last PR fixes it

https://github.com/johmsalas/text-case.nvim/wiki/String-Case-functions

local textcase = require('textcase')
local result = textcase.api.to_dash_case('Dash case')

I haven't setup a template for issues, a good question would be, what are the reproduction steps?

Thanks for your help making better this plugin!

With the latest version, to_snake_case is not mapped to s by default, but if I map it myself, it's works. Thank you. nmap gas <Cmd>lua require('textcase').current_word('to_snake_case')<CR>

This could be updated in the wiki, as it still shows as a default keymap (trigger)
