filter command limitation?

The "Filter" command is compact and powerful. But it is limited in the sense that it only works with "whole" lines, items, keys, etc. In other words, I wish that, given in a field 1:
aa,bb,cc
dd,ee,ff
gg,hh,jj
it would filter out line 2 from the following:
Code: Select all
on mouseUp
get fld 1
filter lines of it without "ee"
end mouseUp
But it does not, since it only sees "whole" lines. Am i missing something here? Is there a way to lose line 2 because it
contains a string, as opposed to the line
being the string?

Hi Craig,
You can use * as a wildcard before/after the filter part. With some possible fudging for beginning/ends of the line and checking for CR as well.

I have a feeling there is a relatively straight forward way to do this.
Currently making Kichiri (marvellous stuff) in the kitchen: will get to the computer in about 30 mins and try out my idea.

Code: Select all
on mouseUp
put empty into fld "f2"
put 1 into LYNE
repeat until line LYNE of fld "f1" is empty
if line LYNE of fld "f1" contains "ee" then
-- do nothing
else
put line LYNE of fld "f1" & cr after fld "f2"
end if
add 1 to LYNE
end repeat
end mouseUp

Oooh. I will try that, and I realize I have done that sort of thing before.
I think the fact that I am filtering
by lines obviates the need to worry about returns or anything else. LC will consider only lines.

That did the trick, of course. I cannot see any traps where too much filtering might occur. Your idea is already, as I thought, restricted line by line by LC itself, and it reads to me that any line containing any string would be deleted.
Thank you.
