Setting the text style of certain words in a field

[LouisThompson]

Hi,

I've played around, searched, but not found anything...
(Sounds like the first line of a Country & Western song

Anyway, I have a field which contains a Python Script.

I'd like to set the text style of certain words...

eg
def, return, import, for : bold, blue
numbers should all be red
comments should be green

I'm happy to parse the field to find the relevant sections and words, but how do I apply the text style atrributes.

Thanks

Louis

I believe the htmlText property in the dictionary may be what you want. You can set many aspects of text styling with it, including colors. Alternately, textStyle / textColor could be used. Just type "text" in the dictionary, there is a lot there

What Bogs said.

The HTML text will allow you to attach style tags to text within, say, a variable. You need to research this as per his suggestion, since this is a powerful tool indeed.

But just to get back to basics, put some numbers and ordinary words in a field. Put this in a button script somewhere:

Code: Select all

on mouseUp
   repeat with y = 1 to the number of words of fld 1
      if word y of fld 1 is a number then set the textColor of word y of fld 1 to "yellow"
      else set the textColor of word y of fld 1 to "blue"
   end repeat
end mouseUp

This will require forethought to parse text , as you say, into several different categories. The "offset" function might come in handy...

Hi Craig, one could quibble, but when I put the following text into a field and ran the code above...

How do you style some text in a field? One, two, 3, 4, who are we for? 100 times 100 is 10000.

I expected all the numbers to turn red. Only 100 and 10000 did. Note 10000 is also followed by punctuation, as is 3 and 4, but 3 and 4 were ignored. I am sure some complicated logic but a numbers a number. If it captures 10000 why not 3 and 4?

You'll want to use the trueWord chunk type rather than word. TrueWord is both Unicode-aware and uses natural-language rules to account for punctuation and other details, where word (for compatibility with older dialects) only uses simple space boundaries.

I've been looking for some Python examples I might use to run comparative benchmarks. This task may be a good fit. How would you do this in Python?
