python_elves: Little helpers written in Python

This repository is meant as a loose collection of python tools for various purposes.

lsconvert

The script takes ls -R output and turns it into a XML file. Sample:

ls -R /home/my_dir > input.log
python lsconvert.py input.log output.xml

-------- input.log -------

/home/my_dir:
oneFile.txt
anotherFile.log
someDirectory
pink_elephant.sh

/home/my_dir/someDirectory:
someMoreFiles
someScript.py
someNestedDirectory

/home/my_dir/someDirectory/someMoreFiles:
very_nested_file.txt
very_nested_program.sh

/home/my_dir/someDirectory/someNestedDirectory:

-------- output.xml -------

<home>
  <my_dir>
    <oneFile.txt />
    <anotherFile.log />
    <someDirectory>
      <someMoreFiles>
        <very_nested_file.txt />
        <very_nested_program.sh />
      </someMoreFiles>
    </someDirectory>
    <someScript.py />
    <someNestedDirectory />
  </my_dir>
</home>

JQL Composer

The script is used to compose complex JQL queries from a JSON-encoded dictionary of simpler sub-queries.

It will enclose the expansion of sub-queries in parentheses while expanding, in order to ensure the original precedence.

In order to use one query inside another, use the sub-query's name in brackets inside the outer query. See sample.json for an example.

How Many Do I Need?

The minecraft/hmdin script is basically a counting formatter that can help you keep track of large item quantities in Minecraft. By default, it will print a human-readable listing of all nonzero "units of quantity" necessary to amass the specified amount of items.

You can specify a nonstandard stack size (e.g. 16 for eggs or similar) using --stack-size.

python hmdin.py 256 --stack_size=16
> 256 items are 16 stacks

python hmdin.py 256
> 255 items are 3 stacks and 63 items

python hmdin.py 2000
> 2000 items are 1 chest, 4 stacks and 16 items

The actual helper/split functions are:

hmdin(count, stack_size=64, container_size=27) # will return the tuple of <chests>, <stacks>, <items>
pretty_print(chests, stacks, items) # will format the list of items as human readable (without prefix), e.g. "3 chests and 14 items"
csv_print(chests, stacks, items, separator=",") #will format the list of all three items for CSV output, e.g. comma-separated
