Filter Input from another Filter's output

Can I run a couple of filters in sequence and make the filter's output another filter's input?

Could this be done from the command line?

Thank you

It really needs a higher level 'script' that invokes multiple filters. It's on the drawing board but we haven't started coding yet!

Thank you very much!

Although, technically I could do it in one filter, for organization sake, I want to split the process in two filters.

The first filter is a process that will never change no matter the client that I am working on. The second filter will have some small changes depending on the client. This filter insert records into an SQL table. One of the things that changes is the name of the SQL table. Would be nice to reference it through a global variable (and command line also)

Keep up the goog work!

Another thing... just like the command prompt...

filter | filter | filter | filter

...this would really reinforce the Pipe in TextPipe!

Like M.L.K. said: I have a [Pipe] dream!

Did you know that you can link filters together? It's in the All Available Filters view - at the bottom.

The client-specific filter would like to the generic filter as the first step.

I did not know that and it is really cool

I also would have to adjust it and change the input file to be the input of the "linked" filter. It would definitely work.

Thank you

No - the input comes from the linking filter - any input files specified by the filter you are linking to are ignored. Neat eh?

Very!

You thought this through.
