mega_pwd

Dynamically shorten directory names. Intended for use as part of your $PS1.

How it works

The current working path is split into folders. Each of these folders is then assigned a weight. This weight determines the maximum number of characters that can be used to print that folder. The default algorithm to assign a weight is

y = x^0.5

which means that the closer the folder is to the current working directory (and the higher the x), the more weight it has. There are currently 5 different algorithms defined for computing the weight, which can be readily swapped out.

Demo

The following demo shows how the script performs when navigating down 15 directories. Any files under $HOME are prefixed with a tilde(~). The entire time, the pwd string is below the specified cap of 30 characters.

The other functions are shown below for the same folder:

constant_func_integral, y=1, (medium->medium)

[~/dv/sc/ats/app/cnt/cnc/my_/dem/complete]$ 

linear_func_integral, y=x, (low->high)

[~/d/s/at/ap/cnt/cncr/my_c/demo/complete]$ 

parabolic_func_integral, y=x^2, (high->low->high)

[~/dvlpmn/sch/a/a/c/c/my_/demo/complete]$ 

sin_func_integral, y=sin(x), (low->high->low->high->low->high)

[~/dv/schdl/at/a/cntr/cnc/m/demo/complete]$ 

cubic_func_integral, y=x^3, (low->high)

[~////a/cn/cncr/my_cnc/demo/complete]$
