Issue with matlab code not distinguishing between single quoted strings and matrix transpose operation #346

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Run the following code
<!DOCTYPE html>

<html lang="en">
<head>
   <meta charset="utf&mdash;8">
   <title>untitled</title>
   <link rel="stylesheet" href="prettify.css" />
</head>
<body>

<pre class="prettyprint linenums">
A = [1; 0; 0]
B = [1 0 0]
C = B' + A
</pre>

<script src="prettify.js"></script>
<script>prettyPrint();</script>
</body>
</html>
(Please include HTML, not just your source code)

What is the expected output?  What do you see instead?
' +A; is highlighted in green. I take it that it is assuming this whole part as 
a string cause of the single quoted literal

What version are you using?  On what browser?

The latest prettify on the latest chrome
Please provide any additional information below.

I think that when the single quote (') is right next to a variable, prettify 
shouldn't recognize it as a opening string quote.

Two things:

- first, you need to specify a language hint for MATLAB in the PRE tag:

  <pre class="prettyprint lang-matlab">...</pre>

- second, you need to include the corresponding javascript file to get the 
special MATLAB language handler:

  <script src="prettify.js"></script>
  <script src="lang-matlab.js"></script>

Once you fix those, single quotes are correctly recognized according to the 
context (either matrix transpose or a quoted string)

Shouldn't the project be detecting the language automatically ?

I am only having issues with matlab and for this I have to manually include 
lang-matlab.js other languages are doing fine.

Only for languages included in the core script. Additional languages (like 
MATLAB) are supported as extensions, and must be explicitly enabled.

I can spend a couple of weekends on this. Is there someway I can help make 
Matlab a standard supported language for you guys ? I can help with VB CSS too 
if I get enough time.

I'm sure contributions are always appreciated, but I'm not the project owner. I 
just contributed lang-matlab.js (as an extension), and help maintain it when 
needed :)

I will put a email to the guy who owns it, "soon" see if he would like an extra 
helping hand.

BTW, great extension man, now that I figured it out how to use it !
