How to remove the new line character

Danilo P over 12 years ago

Hi all,

is there a way to remove the newline character at the end of lines read from files?

I did it with:

while(gets(line fileIn)

if( .... then mystring = car(parseString(line "\n") ..............)

Is a skill function available to do that?

thank you

Hi,

from what I know there is no skill function to do it straight forward.

Best Regards,
Marcel

Hi Danilo,
I've used the method that you noted, but you might also do something like the following:

when(rexMatchp("\n$" line) line = strncat("" line strlen(line)-1) ); when the line ends with a carriage return, remove it

I don't know how this compares with the other approach, in terms of speed/resources, so I'll leave that as an excercise for the interested reader ;-)

Lawrence.

Or you could use (in IC61X):

; create this pattern once
cr=pcreCompile("\n")
...
; as you read in each line
mystring=pcreReplace(cr line "" 0)

This is using the Perl Compatible Regular Expression functions, storing the compiled pattern object in a variable, and then using that each time you want to replace carriage returns with nothing.

Regards,

Andrew.
