[ANN] el - an interactive shell-friendly form of Lua

[steve donovan <steve.j.donovan@...>]

Good day!

This all started because I wanted a better console calculator, Python
was irritating me and typing "lua -e 'print(math.sin(2.34))'" was just
tedious. So in its simplest form, el makes calculation on the console
a little easier on the fingers, and can remember things (even
user-defined functions) for later.

$ el 2*sin[pi*2.3]
1.6180339887499
$ el set tau=2*pi
$ el {tau+0.1 tau+0.2}
{6.3831853071796,6.4831853071796}
$ el set f={x: sin tau*x}
$ el f 0.1
0.58778525229247

It was a fun exploration of the idea "what would a shell-friendly
language based on Lua would look like?" and I hope you find it
entertaining, at least.

The Readme is the Article - otherwise just symlink e to el.lua.
(tested with 5.2 and 5.3)
