tyche

tyche is a command line tool, which recursively checks a directory and all of its subdirectories of your research data for (proper) documentation and provenance.

Motivation

If you do not have a central research data infrastructure, i.e. a place to store all your files, which pile up during your research, you will probably fall back to a simple file based storage.

In order to help your future self or colleagues, this tool allows you to check your data folder, and shows you all directories which are missing a README (or whatever documentation file you require).

Furthermore it can check, that all files are adjoined with provenance information.

Installation

Install the latest version from github:

$ pip install git+https://github.com/diggr/tyche

Quickstart

A directory can be checked, by simply calling tyche check. If no directory is supplied, the current working directory will be checked.

$ tyche check [DIRECTORY]

Directories which passed the checks will be displayed in green, failed directories will be displayed in red. If at least one subdirectory failed one check, the return code of tyche check will be 1, else 0.

To show all possible commands and options invoke:

$ tyche --help

Check Command

To disable checks, simply exclude via the command line option, e.g. to diable provenance checks enter:

$ tyche --no-provit check [DIRECTORY]

Option	Result
--no-provit	Disable the check for provenance files.
--no-readme	Disable the check for README files.

There are some options to tweak the output:

Option	Result
--quiet	No output at all.
--omit-correct	Correct / Passing directories will not be displayed.
--non-recursive	Subdirectories of the given directory are omitted.

Report Command

The report command will return a json dict, with specific information about all directories and the checks they passed or failed.

$ tyche report [DIRECTORY]

You can directly pipe the result into a json processor, e.g. json_pp to display it.

$ tyche report /media/v/Diggr/_ARCHIV | json_pp

This will result in this output:

{
   "/media/v/Diggr/_ARCHIV/Datenquellen/UB-Spielesammlung/2016-04" : {
      "readme" : false,
      "provit" : false
   },
   "/media/v/Diggr/_ARCHIV/Datenquellen/VGChartz" : {
      "provit" : true,
      "readme" : true
   }
}
