Wordfilter issue

[tpenn]

I'm having an issue with the word filter. I'm on RC-1b, with the filter set to Blacklist.

I received a massive list of words to filter from my publisher and am seeing some issues. An example will be the easiest way to illustrate. I'll use some of the...less offensive words for this.

The words I've been asked to filter include these: fart, farted, farts, farting, and farthead.

I add them to the wordsFile.txt, following the pattern established in the provided sample file. Thus, I end up with regular expressions looking like (?i:fart), (?i:farted), etc. to do case insensitive searches for these words.

Testing it out, I get some strange results.

Sending "fart" outputs ****. Good so far.
"farted" outputs ****ed. Looks like it took that first match and quit.
"farts" outputs *****. I had expected ****s based on the last one, but was surprised.
"farting" outputs *******. Again, it found the best match.
"farthead" outputs ****head. And now back to only matching "fart".

It's the inconsistency that surprises me. Now, I know I can make the expression for "fart" only look for a whole word and solve some of my issues. But unless I'm missing something, this felt like a bug, so I thought I had better make a report.

The WordFilter in SFS2X is based on regular expressions so you can be quite advanced with the string matching.
I would recommend to check some basic websites in order to learn about regular expressions and experiment a bit with them.

Take a look here for example:
