This is also happening for C haven't tried other language yet.

This was happening in all languages. It should now be resolved.

@filNaj Thanks a lot for the effort put in to the plugin, if time permits can you explain how, how adding return fixed the issue. I tried fixing the issue myself and couldn't find out the root cause. I'm noob on lua and neovim plugin dev but I would like to learn and contribute whenever possible.

[filNaj]

Adding return prevents the code to continue any further and reach the if statement at the end of the setter.lua file. This if statement is used to insert a ; when the user presses on the enter key (and not the space bar) to go to the next line. This is done by calling vim.api.nvim_buf_set_lines() function. But in the if character == ':' block, we are already calling this same function but with different arguments. So by adding the return, we prevent the vim.api.nvim_buf_set_lines() to be called twice.

Hope that helps.

@filNaj thanks a lot for taking time to explain, it makes sense now, I didn't know that with lua you can return without any value. Thanks a lot explaining the scenario 🙏 ❤️
