Auto detect file format, second attempt #222

Closed rjleveque closed 2 years ago

rjleveque commented 7 years ago

This requires clawpack/pyclaw#581.

The default ClawPlotData.format value is now None, indicating that pyclaw should figure it out for itself.

I added a function ClawPlotData.getframe_time that is now used in plotpages.py to only grab the times, in place of the deprecated OutputController function.

While I was at it, I also added a function ClawPlotData.getframe_list that returns a list of all the framenos found in plotdata.outdir and the corresponding time, and a function to Iplotclaw so that this can be easily invoked at the interactive PLOTCLAW> prompt, with output like this:

PLOTCLAW > list
Frames found in _output:
Frame number 0 at time t = 0
Frame number 1 at time t = 0.25
Frame number 2 at time t = 0.5
Frame number 3 at time t = 0.75
Frame number 4 at time t = 1

I've been meaning to do this for a long time!

Looks good to me. I really like the listing!

There is actually a read_t() function in the pyclaw/fileio/*.py files; it might be nice to use that here so that we don't need to maintain two functions that do the same thing. Should make this code simpler, too. And petclaw/fileio/petsc.py has a read_t() function too, so this should also then work for those files.

File format is now specified in the fort.t* files, see the discussion at https://github.com/clawpack/geoclaw/pull/533.

So there is no need to try to auto-detect it.
