JACL (JavaScript Assisted Common Lisp) is an experimental Lisp system for the web browser platform. It was created to explore new techniques for large-scale SPA (Single Page Application) development in Lisp.

Specifically, the project goals are to:

  1. Implement a useful subset of CL
  2. Interoperate efficiently with JavaScript
  3. Host as much development tooling as possible in the browser so that tools may organically evolve with the applications they’re used to build
  4. Support the delivery of applications competitive in size and speed with respect to those produced by JavaScript tools

Why not JavaScript?

# Like choicesWithNames(), but returns a data frame of value, label, and
# optgroup columns. This rectangular view could also be thought of as the set
# of paths into the choicesWithNames() tree.
# For example, given a choices argument like this:
# list(a = 1, B = list(B = 2), c = list(3))
# choicesWithNames() would return a tree like this:

Installing R-devel on Solaris 10 VM

As far as CRAN is concerned, there are two flavors of R on Solaris: one that is built using the Solaris Studio compiler, and one that is built using the GNU/gcc toolchain. The latter is far more up-to-date, but if your package requires it, then your DESCRIPTION file must declare that with the line SystemRequirements: GNU make.

These instructions are for configuring, building, and installing R-devel using the GNU/gcc toolchain (only).

You'll need VMWare Fusion on Mac, or VMWare Workstation (?) on Windows/Linux.

Get Solaris VM

Download the Solaris VM provided by Jeroen Ooms:
