Hi all.

I've written a snippet which outputs the contents of another snippet as html. I use it on my site to display the snippets I've written or modified. http://mindspill.net/computing/cross-platform-notes/modx.html

Nice snippet! 

That'll save me a bit of time copying and pasting ...

Cheers, Garry

BTW guys, to do this, there is already a built in API function; no extra snippet required!

Code:

$snippetName= 'MySnippet';
$snippetParams= array('param1'=> 'value1, 'param2'=> 'value2',);
$html= $modx->runSnippet($snippetName, $snippetParams);

Not sure why this is not included in the online API documentation, but I'll get that taken care of this weekend.

Let me know if you have any questions on usage.

I thought that this snippet only showing the code in plain text, instead of running them, am I getting this whole discussion right or what?

Sorry, I might not get the whole discussion in here.

It doesn't run the snippet, it just outputs the snippet's source code as plain text.

Sorry guys, I didn't realize this when I read it the first time.  Thanks for the clarification.

lol, Jason, I think you just did way too much programming lately. Time to take a break for a while

I believe there is an Etomite snippet that does this with syntax highlighting, etc.

Hi.

I've found the etomite snippet. It's called DisplayCode and it's on the second page of their miscelaneous snippets... http://www.etomite.org/browsesnippets.html?int_page=2&lst_category=10 (I didn't link directly to the snippet because I don't think it's allowed). Ok, that's not allowed either!

I tried it but got a lot of odd characters that couldn't be interpreted by the browser and "Warning: Unexpected character in input" warning messages. Also, some characters, like < and >, aren't encoded into html so the doc is still being interpreted as php (hence the warning messages).

Test page here: http://mindspill.net/computing/cross-platform-notes/displaycode-snippet-test.html

If anyone gets it working (or if I'm using it in the wrong way) please let me know.

Updated this slightly to use php's syntax colour highlighting.

Added optional &noHighlight parameter to just display normal html output.
