# Set $DOTFILES to where you want to put your dotfiles.
# then run dotfiles-init someSoftware,
# and it will move all files starting with `.someSoftware` to the correct location
# then link them back,

# $ tree -aL 2 ~/Dropbox/Code/config/dotfiles/

This script has been used to analysis some gene test result in "tab separated value" format from some lab of ZJU. It saves tons of silly people's labor pasting two rows from two different xlsx to graphpad, click some analysis button and copy result back to the third xlsx. However, there is a drawback of this script: it's not parallel.

String padding

https://gist.github.com/Jamesits/30acd725d5fdfb67eae4
Make a string fixed length by adding blank chars between or after it.
Usage:
"123".lpadding(5) // returns " 123"
"123".lpadding(5, "0") // returns "00123"
"123".lpadding(2) // returns "23"
"123".rpadding(5) // returns "123 "
