How do you do the following?
I have a series of lines which go like this
| [record separator, new record starts]
AAA consectetur adipisicing elit, sed
BBB lorem ipsum
CCC consectetur adipisicing elit, sed
CCC laboris nisi ut aliquip ex ea
DDD ut aliquip ex ea commodo
| [record separator]
AAA adipisicing elit, sed [new record starts]
| is the record separator.
In the above, its CCC that is repeated, but it could be any prefix. Also CCC
is next to its repetition. This will always be the case.
I want to go through the file. When I find a single prefix (like AAA) this
should be written to the output file. when the next line starts with the
same prefix (as in the CCC cases, I want to put both occurences on the same
line. So the desired output would be
AAA consectetur adipisicing elit, sed
BBB lorem ipsum
CCC consectetur adipisicing elit, sed CCC laboris nisi ut aliquip ex ea
DDD ut aliquip ex ea commodo
EOR
AAA adipisicing elit, sed
How do I detect a repetition of that sort and do this?
Here's a simple script that does what I think you want ....
on mouseUp
put "x" into tSeparator # should be TAB, but for testing that's
inconvenient
put field "F1" into lInput
put "" into lastPrefix
put "" into lastSeriesOfLines
repeat for each line L in lInput
put char 1 to 3 of L into tPrefix
replace tSeparator & tPrefix with tPrefix in char 4 to -1 of L
if tPrefix = lastPrefix then
put L after lastSeriesOfLines
else
put lastSeriesOfLines & CR after lOutput
# NB this assumes record separator comes on its own on the line
put tPrefix into lastPrefix
put L into lastSeriesOfLines
end if
end repeat
put lastSeriesOfLines & CR after lOutput
put lOutput into field "F2"
end mouseUp
A similar question, if the line is
CCC adipisicing elit, sed TAB CCC adipisicing elit, sed
How do you detect the multiple occurence (I can do this with regex) and then
write out in place of thie above expression (this I don't see how to do) the
following:
CCC adipisicing elit, sed CCC adipisicing elit, sed
See the "replace" line of the script above. Note - I was using input
fields, so the TAB was a nuisance, hence the introduction of tSeparator
.... You may need to adjust for whether spaces are significant, etc.
