Hello,

Textastic 2.2.1 came with a syntax definition for SecondLife LSL. 

 
In Textastic 3.0 it's not built-in, but you can get a TextMate bundle from http://digilander.libero.it/usemac/tm.zip and add it to Textastic yourself:

I've found the link to this TextMate bundle for LSL in the following SecondLife forum thread: http://forums-archive.secondlife.com/54/ae/89389/1.html It seems to be well-maintained.

There is also another one in TextMate's SVN repository at http://svn.textmate.org/trunk/Review/Bundles/SecondLife%20LSL.tmbundle/

Hello,

Textastic 3.0 uses TextMate syntax definitions and themes for syntax 
highlighting.

Now you can also add your own syntax definitions. This is explained in 
the manual athttp://www.textasticapp.com/v3/manual/lessons/How_can_I_add_my_own_syntax_definitions_and_themes.html

Here is a bundle for Verilog: 

VHDL:

Can you please explain what you mean exactly? Syntax Highlighting is built in. You can copy TextMate bundles even when you have a Windows PC - you don't need TextMate or a Mac. 

There are 163 TextMate repositories at https://github.com/textmate - and many more can be found by searching for something like "language textmate bundle" or "language tmbundle".

Hello, Textastic 3.0 supports custom syntax definitions that are compatible with TextMate.

Yes, this is unfortunately a problem in iOS 5. It seems to cache the CSS file although it shouldn't. This doesn't happen in iOS 4.

Increment the counter when you make a change.

I will try to fix this in an update.
