Adventures in Code V: making a map of Igor functions

I’ve generated a lot of code for IgorPro. Keeping track of it all has got easier since I started using GitHub – even so – I have found myself writing something only to discover that I had previously written the same thing. I was thinking that it would be good to make a list of all functions that I’ve written to locate long lost functions.

This question was brought up on the Igor mailing list a while back and there are several solutions – especially if you want to look at dependencies. However, this two liner works to generate a file called funcfile.txt which contains a list of functions and the ipf file that they are appear in.

grep "^[ \t]*Function" *.ipf | grep -oE '[ \t]+[A-Za-z_0-9]+\(' | tr -d " " | tr -d "(" > output
for i in `cat output`; do grep -ie "$i" *.ipf | grep -w "Function" >> funcfile.txt ; done

Thanks to Thomas Braun on the mailing list for the idea. I have converted it to work on grep (BSD grep) 2.5.1-FreeBSD which runs on macOS. Use the terminal, cd to the directory containing your ipf files and run it. Enjoy!

EDIT: I did a bit more work on this idea and it has now expanded to its own repo. Briefly, funcfile.txt is converted to tsv and then parsed – using Igor – to json. This can be displayed using some d3.js magic.
