Build, Install, and Run a Chrome App without Chrome

Until [app_shell] is created, here is a workaround for building, installing, and running a standalone [Chrome App] for Windows.

Step 1 - Pack Your Chrome App

1. Use chrome://extensions to package your app. The approach we're outlining here doesn't work for unpacked apps.
2. You should have a .crx file that is your packaged app.

Reader Macros in Common Lisp

This post also appears on lisper.in.

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.

In considering where Objective-C could go, it's worthwhile to start by understanding the work that's already been done.

Below are a selection of papers from Gilad Bracha's 1990s work on Strongtalk, an extension of Smalltalk (from which Objective-C's design derives) with (among other things), stronger type-safety tooling.

What's interesting (to me, anyway), is that the work done on the Self/Strongtalk VM in the early 90s was actually bought by Sun and became the modern Java VM. When Google got started on their V8 JavaScript runtime, guess who shows up again — Lars Bak, who was the technical lead for both the Strongtalk and HotSpot Java VMs.

If we're going to be talking about how to apply "modern" (1990s!) ideas to Objective-C, we'd be wise to review the considerable work done in considering those sorts of problems in a Smalltalk-derived universe, and lifting whatever good ideas we can, and discarding
