Toggle softwrap

[haqk]

Is it possible to implement a ToggleSoftwrap action?

You can do this with some Lua code. Place the following in ~/.config/micro/init.lua:

function toggleSoftwrap(bp)
    bp.Buf.Settings["softwrap"] = not bp.Buf.Settings["softwrap"]
end

Then in ~/.config/micro/bindings.json you can bind this action with

{
    "Alt-r": "lua:initlua.toggleSoftwrap"
}

That works, but only if I run under sudo. If I open micro as a normal user I get:

function does not exist: lua:initlua.toggleSoftwrap

Press enter to continue

Any clues?

It looks like you might have a recent version of micro installed for sudo and an old version installed for your normal user. I recommend checking the version and upgrading to the latest version.

Why won't you implement a toggle for soft wrap by default. Other command line editors can toggle soft wrap via a keybinding or a command like Nano, Vim and Emacs. It would be more convenient for users to do it through a simple toggle rather than having to bind it through Lua or changing the config each time.

I could second that. set <option> <value> is used for setting an option, and i think a toggle <option> command would be nice. It would work only for boolean options and generate an error if it is used for example with a number option.

And perhaps also togglelocal (similar to setlocal).

I currently have the following in my bindings.json

{
    "Alt-Z": "command:set wordwrap on,command:set softwrap on",
    "Alt-z": "command:set wordwrap off,command:set softwrap off",
}

and it works really well for me. I would prefer if the same key was used to toggle, as opposed to using a shifted version of Z to turn it on. Note that alt+z is the default keybinding is VSCode, which is a good argument for enabling this by default with that keybinding in micro.

As I wrote in https://github.com/zyedidia/micro/issues/2086#issuecomment-826351299, a generic toggle command can be quite easily implemented in Lua. But perhaps it's time to implement it in Micro itself, to have it out of the box, since quite a few people express interest in this feature.

Then you'll be able to use "Alt-z": "command:toggle wordwrap,command:toggle softwrap" (though in this specific case I'd still write some Lua code to make sure that the values of softwrap and wordwrap stay in sync. I.e.: toggle softwrap and set wordwrap to the same value as softwrap.)
