string with new line

[Philip]

I can not figure what is wrong with this and I tried all things but I still can not figure out.

Open SHH connection  |  ${host}

Login   ${name} | ${pass}

Write   | ls abcd*.iso

${fileIso}= | read until regexp | #

Log  | ${fileIso} 

      # ${fileIso} = abcd1.-1.5.1.SNAPSHOT.4165.iso            

Log  | mount -o loop ${fileIso} ${directory}                     #where ${directory} is an argument

The output will be

 # moutn -o loop abcd1.-1.1.1.SNAPSHOT.29888.iso         #abcd-directory jumps to a next line

 # abcd-directory

So I wrote a python code to replace \n or \r with " " for the variable ${fileIso} and

I also removed the remove a while space before and after of the variable ${fileIso"

Log still shows a new line for the ${directory} variable

Log  | moutn -o loop ${fileIso} ${directory}                     #where ${directory} is an argument

The output still show

 # mout -o loop abcd1.-1.1.1.SNAPSHOT.29888.iso

 # abcd-directory

Ugh

With out seeing the Python code and snippets what the variables actually contain it's impossible to say anything concrete. But as a wild guess I would assume that your Python code is not doing what you assume.

As a side note you don't need to build a new keyword to remove a whitespace from a string. There is a Strip String[1] keyword in the String library, which does the trick.

The python code I wrote:

def strip_charreturn_newline(string1):

    output = string1.replace('\n', "")

    output = string1.replace('\r', "")

    return output

i think you should focus on the location where you get the ${directory} values... there should be the problem? what way do you get this value? but as tatu wrote, you can use the strip string keyword to remove leading and/or trailing whitespaces.

${directory} is an argument and the value is input value. for example, "abcinstall"

I noted above that the ${fileIso} gets a value from the sshlibrary.write  | ls abcd*.iso and the ${directory} is a value which is passed to an argument/

[Heiko Thiery]

ok .. 

the problem seems to come from here:

Write   | ls abcd*.iso

${fileIso}= | read until regexp | #

there you read till the prompt of your shell. but the prompt appears after a newline.

try to change your code to use the execute command from ssh library. then the correct prompt will be stripped.

Open Connection  ${host}   prompt=#

${fileIso}  ${rc}=  Execute Command  ls abcd*.iso  return_rc=True

Should Be Equal  ${rc}  0  msg=Return code is ${rc} but should be 0.

Log  ${fileIso}

give it a try ...

I manually count this string (the filename) and it is about 35 characters.

But I use the get length function of string and is is about 56 characters.

I use this python code to trim spaces, new line, character return and the get length function still 56 characters.

 def strip_charreturn_newline(string1):

    output = string1.strip(' \t\n\r')

    output = string1.rstrip(' \t\n\r')

    return output

you know why ?

Also I tested the split function to split this string with space into a list

it has the same issue.

sorry for the trouble.

In fact, I use the start command as you instruct instead of the write command and it works.

The issue as you pointed to.

thanks
