Dynamic task dependency based on task parameter?

[Brad Dixon]

Hello:

I'm stumped on how to implement this behavior with doit:

Task 1: Create PDF

Task 2: Create DOCX

Task 3: Archive

    * Has param "fmt" which can be either pdf or docx.

    * Runs either Task 1 or 2 depending on value of fmt parameter.

    * Has action which copies output to a directory

      with a fancy name.

Intended usage:

doit archive --fmt docx

doit archive --fmt pdf

I RTFM'ed that I can use calculated dependencies to, from another task,

make a decision about what tasks to depend on. I added a task_dep to archive which does

just this. I also read that I could, in the archive task, define an action which stashes

the fmt parameter value so that other tasks can use it. The other task would use getargs

to retrieve this stashed value. The catch, of course, is that I can't use these two

features together because the action that stores the variables runs _after_ the task

that determines what to run.

Any advice on how can I have a dynamic task dependency that is determined by a task parameter?

Thanks,

Brad

can you provide a minimal sample?
easier to reason about and make sure we are talking about the same thing.

Just having 2 different sub-tasks would solve the problem?

Like:

doit archive:docx

doit archive:pdf

Task "params" is something I added to be used in some long running tasks or to modify output printed to stdout.

In your case having 2 different tasks and executing only one of them would make more sense to me.

But not sure you are talking about a contrived example...
