Highlight matching paren on mouse-over #6

Closed priyadarshan closed 9 years ago

priyadarshan commented 10 years ago

It would be very nice to have the option to highlight matching paren on mouse-over, like pastes at paste.lisp.org. See as example the same code of the highlight-lisp demo here: http://paste.lisp.org/display/143836

Thank you for highlight-lisp!

Agreed, this would be cool! It may be outside the scope of the project, but if I find I can do it fairly easily, I'll add the feature. Leaving this issue open until I can make a decision either way.

highlight-lisp will hopefully be used for cl-cookbook (LispCookbook/cl-cookbook#43).

Being able to highlight matching paren on mouse-over would be a good help studying the recipes (at least for absolute beginners like myself).

OK FINE YOU WIN!!

Added paren matching in 93216f5. Works slightly differently than paste.lisp.org (their version is more robust, this one just highlights immediate matches). Pull down master and give it a shot (check out the readme for details)

:smile_cat: Thank you so much for the new feature!

It works wonderfully. A quick test from the example in README:

<html lang="en">
<head>
<link rel="stylesheet" href="/Users/priyadarshan/highlight-lisp/themes/github.css">
<script type="text/javascript" src="/Users/priyadarshan/highlight-lisp/highlight-lisp.js"></script>
<body>

<pre><code class="lisp">(defun test-syntax-highlighter ()
  "Docstring explaining what this function does."
  (let ((hash (make-hash-table :test #'equal)))
    ...))</pre></code>

<script type="text/javascript">
HighlightLisp.highlight_auto({className: null});
HighlightLisp.paren_match();
</script> 

</body>
</html>

Thank you.

I was meant to add a link to what looks related to paste.lisp.org's source colouring. Let me do it now, if I may: https://github.com/stassats/lisp-bots

Thanks again.

Cool, glad it's working well!

@priyadarshan indeed now the CL cookbook uses it :) (https://github.com/LispCookbook/cl-cookbook/pull/64)
