Using replace function

dMathieuD

Hi,
I'm trying to remove space in a string using "replace" function in my project file. I tried a lot of different things like:
@
myNewVariable = bla bla
myNewVariable = $$replace($${myOldVariable}, " ", "")
@
or

@
myNewVariable = bla bla
myNewVariable = $$replace(myOldVariable," ","")
@
or

@
myNewVariable = bla bla
myNewVariable = $$replace(myOldVariable,' ','')
@
or

@
myNewVariable = bla bla
SPACE = ' '
EMPTY = ''
myNewVariable = $$replace($${myOldVariable}, $${SPACE},$${EMPTY})
@
or

@
myNewVariable = bla bla
SPACE = ' '
EMPTY = ''
myNewVariable = $$replace(myOldVariable,SPACE,EMPTY)
@
Each time I get myNewVariable empty.

Did I miss something ? Is it something not possible to do with replace function ?

What the hell? You're supplying the wrong variable name to replace. And you need to enclose a string with spaces in quotes.

@
VAR = "foo bar baz"
VAR = $$replace(VAR, ' ', '')
message($$VAR)
@

correctly prints

@
Project MESSAGE: foobarbaz

Sorry for bad edition I was meaning:

@
myNewVariable = bla bla
myNewVariable = $$replace(myNewVariable,' ','')
@
And indeed this is working but it was a bit more complicated for me as I was using "system" function like this:
@
myOldVariable = "Foo Bar Baz"
myNewVariable = $$system(echo $${myOldVariable} | tr 'A-Z' 'a-z')
myNewVariable = $$replace(myNewVariable,' ','')
@
which prints
@
Project MESSAGE: foo bar baz
@
but this:
@
myOldVariable = "Foo Bar Baz"
myNewVariable = "$$system(echo $${myOldVariable} | tr 'A-Z' 'a-z')"
myNewVariable = $$replace(myNewVariable,' ','')
@
correctly prints:
@
Project MESSAGE: foobarbaz
@
But the best way to do the trick for me is like that:
@
myOldVariable = "Foo Bar Baz"
myNewVariable = $$lower($$myOldVariable)
myNewVariable = $$replace(myNewVariable,' ','')
@

It's such a shame that functions like "lower" or "upper" are not documented in the official documentation at http://doc.qt.nokia.com/4.7/qmake-function-reference.html. Is there good reasons for that?
