I had the same initial impression of the problem and did a drill down into the
source data. The source data was consistent in its use of tabs and displays
fine with several different editors.
In this case it is a bug with Codestriker. The code views fine everywhere but
in Codestriker.
Only Codestriker fails to display the source properly.
Yes I agree mixed white space is evil and I set up coding standards elsewhere
to avoid the problem, however, it is not a requirement here.
I've provided details of the data below as examining the generated display from
Codestriker showed that Codestriker is not expanding tabs consistently and is
definitely a bug in Codestriker.
The problem seems to be something interfering with correct tab expansion logic
when a line has parenthesis '(' or ')' in them. Lines with a parenthesis in
them do not have correct tab expansion of 4 or 8 spaces.
Please review the data I originally presented to see the problem. There are no
mixed space/tab lines yet the tabs get unevenly substituted for spaces.
This is also reflected in the 4 space expansion I've provided. Once again
there is irregular tab expansion on lines ith parenthesis on them.
Bye for now,
Chris

Hi Chris,
This is the problem with tabs.. and why in my work place, our IDEs
specifically are setup to not use them. What you are seeing is quite
normal, if you load your file into an editor with different tab-stops
(8 instead of 4), you'll see the same behaviour.
Cheers,
David
