My emacs init file for 2015
I’m going to make it a tradition to post my emacs init file every year and compare it to the year before, although I won’t post the file I used in 2013 and 2014 I can simply state that the biggest change is that I’ve thrown out ECB.
ECB simply didn’t work for any other language than Clojure and PicoLisp and not very well at that plus a working find-tag via jump-to-current-word simply renders the point of ECB moot. However it would be kind of nice to be able to run a command to open a new buffer with links to line numbers for all definitions in the current file, shouldn’t be too hard to implement either, we’ll see if I manage in 2015. ECB is out anyway.
Another simpler TODO for 2015 is fix flymake for PHP so that it doesn’t break down and cry all the time when it encounters error strings it can’t recognize.
Without further ado, here it is:
