Add oneshot mode to sync clipboard

[kaihendry]

When I copy from my terminal, I've noticed that sometimes the default sleep of 0.5 is not quick enough to synchronize, leaving my clipmenu-url to act on the wrong URL for example.

Clipmenud's loop needs to be refactored into a function so I can call clipmenu from st directly.

Can you show me clipmenu-url? I didn't find it in your dotfiles.

Your solution doesn't make much sense. It doesn't sound like you want a function, it sounds like you want a oneshot mode.

Yes, oneshot "request the clipboard manager to take over the ownership of the clipboard" as put on http://askubuntu.com/a/61328/676

Sounds reasonable enough.

@kaihendry do I understand correctly that you are trying to launch your browser from the selected text? You're trying to take a very roundabout approach to this. The better way is to use a more direct approach with xsel.

xsel -co | xargs -r xdg-open
This prints the currently selected text to stdout, which we pipe to xargs so that xdg-open can receive it as an argument.

Replace your clipmenu-url with this single line of code :)

This is a very good suggestion, thank you! The only drawback is that I may want to use the script on the last URL after making another non-URL selection, if that makes sense?

[AeliusSaionji]

Sure. To accomplish that, I would combine your approach and mine.

Something like

#!/bin/bash

LC_COLLATE=C

if url=$(xsel -co > /tmp/sel && grep --only-matching --perl-regexp "http(s?):\/\/[^ \"\(\)\<\>\]]*" "/tmp/sel")
then
    xdg-open $url
else
    files=(/tmp/clipmenu/*)

    for (( i=${#files[@]}-1; i>=0; i-- )); do
        file=${files[$i]}
        if url=$(grep --only-matching --perl-regexp "http(s?):\/\/[^ \"\(\)\<\>\]]*" "$file")
        then
            xdg-open $url
            break
        fi
    done
fi

I have not tested this, you might have to make some adjustments.

Weird, xsel -co doesn't output anything for me on Arch.

[AeliusSaionji]

For the past week or so, clipmenud has not worked for me, and actively prevents me from copying anything. I've been meaning to make an issue but haven't found the time to dig into what caused this. Does xsel -co work for you if clipmenud is not running?

[kaihendry]

xsel -co is not working at all.

Reverted to using xclip again with

if url=$(xclip -o | grep --only-matching --perl-regexp "http(s?):\/\/[^ \"\(\)\<\>\]]*")

Easy enough now that we have locking support, see db05c51 :-)
