tip: copying chunks of code to clipboard

[Rustem]

I keep a TiddlyWiki for documenting bits of code, scripts etc. In TWC, I had a homegrown plugin that added a “Copy All to Clipboard” button to every code block. (Eventually, it degraded to “Select All”, when manipulating the clipboard from a web page became impossible, with tightened security in a newer version of Firefox.)

I was missing that functionality in TW5, but didn’t want to rewrite the plugin since I would not be able to make it copy to clipboard anyways. Finally, it occured to me that there might be a browser add-on that could do the same. All that is required is copy inner HTML from an element on a right click. It wasn’t easy to find, but there it is: https://addons.mozilla.org/en-US/firefox/addon/texttotag/

After installing it, right click on your piece of code, select “TextToTag” from the menu and voila - the code is in your clipboard.

When clicking, make sure you are pointing to the text, and not to the whitespace between the lines or on the right-hand side in a block of code. And if you find that limitation inconvenient, you can click anywhere within the block of code if you add this to your stylesheet:

pre code, pre.hljs code { display: table; }

Enjoy!

HI Rustem,
it is also possible to use tiddlyclip to copy hightlighted chuck of a web page as html and have them appear in a tiddler, just replace @text with @web in the snip rule:-

BJ,

I think you misunderstood. I was describing a way to copy a fragment of code from a wiki to clipboard, for when you actually need to reuse it. The entire contents of a <code>...</code> tag, without having to drag your mouse across it to highlight everything. (If you want only a part of it, you'd still have to do the usual highlight+copy way.)

Rather than having a multitude of small scripts, I keep them in my wiki, commented and tagged, and just copy and paste them into command line when I need to run them.  I guess it's a somewhat specific use case, not everyone will find this useful enough to bother.

Ah - I did misunderstand. I used to use a firefox extension called 'terminalrun' (now defunct) that would automatically hightlight linux commands in all pages and you could run them by clicking on them (not very secure!)
