#giveupthefunc

Go function use profiling.

How many times are you really using that?

##Usage

giveupthefunc determines the number of times a function is called with some set of packages.

You specify the scope of your analysis using a regexp with the -p flag. For each package and dependency this flag matches, giveupthefunc will track all function declarations and all function uses within that package. It then prints a summary of those stats for all the packages.

Here's an example using one of my own packages, setting the scope to my github repos.

$ giveupthefunc -p='github.com/ericchiang' github.com/ericchiang/pup
