How to make fpp only output the file list, so that you can plug in any file picker about pathpicker

[pcottle]

It would also make more sense because a unix tool should try to do one thing well. I think with this in mind, it would even make sense to have two utilities that could together work as a path picker : the first one which does only the conversion from an output to a list of filenames, the second one which gives an UI to select one or more elements from a list.

Yeah, this has come up a bunch internally and externally. I'm a huge fan of the unix philosophy but I actually think a lot of the value of PathPicker is added by being a "one-stop shop" for everything you need to do with paths. Had we gone more unixy we would either have just:

1. built the parsing of files and outputted those, or
2. built the UI selector and worked with any kind of input

But neither of these would have been that great. With 1) developers would still have to do awkward xargs things (or put the command in a subshell like $(ls -l | fpp) which I find annoying). With 2) the input would require a lot of prep with regexes and sed to get into an acceptable format for selection (think of all the work git diff or git diff --stat requires)

so we had to go into brave new territory and do a very non-unixy thing here, but I think it ended up really striking a perfect spot between utility and simplicity.

Anyways, I think it'd be quite easy to fork this project and refactor it to just output the list of files (basically remove the $PYTHONCMD "$BASEDIR/src/choose.py" < /dev/tty line and simply print the list out from python), but I don't think this is something we can support easily since. Let me know if you need pointers on the fork though! Who knows, maybe the fork would become more popular one day :P

Hi, If I do the following:

function doProgram {
  # process input from pipe and store as pickled file
  $PYTHONCMD "$BASEDIR/src/processInput.py"
  # now close stdin and choose input...
  exec 0<&-
  # $PYTHONCMD "$BASEDIR/src/choose.py" < /dev/tty
  # execute the output bash script
  # sh ~/.fpp/.fpp.sh < /dev/tty
  cat ~/.fpp/.pickle
}

I don't get the list of filenames as a result. Where can I get the list of the possible files ?

Here is what I get with ls | /.fpp

Found how to make it work now, I will be releasing a fork

Yeah the issue with cat ~/.fpp/.pickle is that those are pickled bytes from python, not plaintext. Sounds like you figured it out but heres a simple way to print out all the files from the pickled state:

[pcottle:~/Dropbox (Facebook)/wip/PathPicker/src:master]$ python

>>> import format
>>> import pickle
>>> fileHandle = open('/Users/pcottle/.fpp/.pickle', 'rb')
>>> lineObjs = pickle.load(fileHandle)
>>> matches = [lineObj for i, lineObj in lineObjs.items() if not lineObj.isSimple()]
>>> for match in matches:
...   print match.getFile()
