This is so that the atom.desktop file will be able to find the
"atom" icon when requested. This adds the dependency of ImageMagick
to convert atom.png to varying resolutions, although, only during
the rpm build process (not during actual install). So the result
is ultimatly no different for the end user.
Also, fixed an absolute path from the rpm build process and made
it relative. It was hardcoded in the spec file to
"/tmp/atom-build/Atom/*", so builds that were made elsewhere would
have broken when attempting to package into an rpm. Now rpm packaging
should work from a build made anywhere. Also needed to modify
script/mkrpm so that it copies the build files in such a way that
they can more easily be dealt with in the spec file in a relative
way.
With the atom atom executable now located in /usr/bin instead
of /usr/local/bin, it should always be available as part of the
system PATH. Thus hardcoding the filepath is not needed. Also, this
increase the flexibility of relocating the rpm at installation time
(not just build time) since the user or sys admin need only make
sure that the atom executable is in the system PATH and the
atom.desktop file will work correctly.
This makes Atom a better desktop citizen relocating to where the usual install
directory is (like on the debian package) and also fix the icon using absolute
paths, breaking icon-themes.
In the spirit of supporting JavaScript development for Atom packages,
this adds default support for es.next transpilation support in the way
that Atom already has default support for CoffeeScript transpilation.
There are many new features in ES6+ that make JavaScript development
easier and more enjoyable, particularly in terms of support for async code.
For reference, this was a much faster way to iterate on this than running `./script/build`
each time:
```
cp /Users/mbolin/src/atom/static/index.js /Applications/Atom.app/Contents/Resources/app/static/index.js
coffee --output /Applications/Atom.app/Contents/Resources/app/src --compile /Users/mbolin/src/atom/src/esnext.coffee
```
Run the following in the console to see how warm the cache was after startup:
```
global.require('../src/esnext/').getCacheHits()
global.require('../src/esnext/').getCacheMisses()
```
