Building Terminal Emacs on OS X

Building a terminal version of Emacs on OS X is easy. However it took me quite a bit of time to land on the correct incantation:

$ ./autogen.sh
$ ./configure --without-x --without-sound --prefix=/usr/local
$ make bootstrap
$ sudo make install

Fixes to A. Sanjeevs' Vue.js tutorial

If you work through [Anirudh Sanjeevs'][sanjeev] excellent tutorial on setting up a [Vue.js][vuejs] project with [Webpack][webpack] and some other goodies, you'll probably hit a handful of minor problems. The tutorial was written a year ago and things have changed a lot since then which naturally explains the issues. So let's tackle them one by one.

The first problem is that Vue.js fails to mount the app component and raises the following error:

#!/usr/bin/perl

use strict;

my %fg = ();
my %bg = ();
for my $i (0 .. 255) {
    $fg{$i} = "[38;5;${i}m";
    $bg{$i} = "[48;5;${i}m";
}
