Done to make bin/doom produce better debugger output (and more readily).
A lot of bin/doom errors aren't recurring, so it's better to produce the
full error report ASAP.
The `term.el` package defines an environment variable `EMACS` inside its shell process, containing the Emacs and term.el version, in a string that looks like this: `26.1 (term:0.96)`. This interferes with the `bin/doom` command, which expects that environment variable to be a path to an Emacs binary. Trying to run make inside a doom terminal thus gives you this error:
```
Emacs isn't installed
make: *** [Makefile:5: all] Error 1
```
This simple fix just checks if `$EMACS` looks like a term version string, and ignores it if so.
As an alternative to the -e/--emacsd options. Sometimes it is more
consistent to customize bin/doom this way. e.g.
EMACS=/another/bin/emacs DOOMDIR=~/someplace EMACSDIR=~/emacsd bin/doom install
Another refactor, again to improve the locality of doom errors and make
the data that accompanies them more useful in determining the origin and
source of issues. Also, bin/doom is now a little more informative about
how to debug errors.
This commit adds bin/doom, which acts as the middle man that make once
was (and will stay for a while, though the documentation will shift away
from using it). It does everything the previous make interface did, but
is faster and more flexible. bin/doom should eventually replace the
makefile.
bin/doom also makes it easier to run Doom outside of ~/.emacs.d and
~/.doom.d with, for example:
bin/doom run -p ~/.other.doom.d/ -e ~/.other.emacs.d
bin/doom.cmd is included for Windows users, but I don't recommend using
it yet. It hasn't been tested nor have I ever written a batch script
before.
Also update init.example.el with new defaults.
