Only syntax highlight after period

pieterjanvc

Hi,

I was wondering how I can setup my user defined language to have some keywords only highlighting when they are prefixed by a period (like when you’re calling an attribute of something).

Example:

MyObject.length --> ‘length’ should be highlighted

length = 5 --> ‘length’ should NOT be highlighted

Thanks for any input!

Under Language->Define your language … click on the Keywords Lists tab. In the 1st group, click on Prefix mode and then enter a period in the text box. Use the Styler button to choose the way you want the text to look.

Hi,

Thank you for the reply, but unfortunately, what you suggest does’t work for the following reasons:

Using the period as a prefix for highlighting only works if it’s preceded by a space (which is useless in the code). ‘MyObject .length’ will highlight, but ‘MyObject.length’ won’t
If you use it as a prefix, you can’t set it as a deliminator anymore so anything after a period will highlight, not just the words you want

Any other ideas?

Last thing I can think of that may (but probably will not) work for you is to define a Delimiter style having:

Open: .
Escape:
Close: ((EOL))

This will highlight every period to the end of the line.
