Canvas replace function

[rozling]

I'm working with Canvas a lot at the moment so please excuse all the questions...

Can anyone give usage examples of the replace function?

I would expect something like this to work:

| mapColumn service fn={replace "-","_"}

which results in: Unable to parse expression: Expected "|" or end of input but "=" found.

or:

| mapColumn service.replace("-","_")

but this results in the error Unable to parse expression: Expected "|" or end of input but "(" found.

Am I misunderstanding something fundamental about this function?

Try this:

| mapColumn service fn={getCell service | replace "-" replacement="_"}

Hi Lukas,
