Get start with "lisp"

Get start with "lisp"

In hacking and comics, Paul Graham mentioned what is the best programming language. LISP and C are obviously mentioned, and it is probably the same as lisp. Recently, I was going to read the tool. So I learned the extremely powerful lisp.

The basic, if primitive, way to get lisp running is to install a command-line lisp system. this works especially well if you have a UNIX System (OS X or Linux ). command-line lisps include:

• Sbcl is a recent revision of cmucl with new modifications and additions.I recommend sbcl as the best command-line lisp.However, sbcl is very verbose and warning-filled though, which can get quite annoying. on the Mac, if you prefer a quieter, more forgiving, and decently fast lisp, try CCL or MCL.

• Clisp is a good common lisp, and is highly portable to nearly every environment out there. however, the reason it is portable is that it compiles to a bytecode interpreter rather than to machine code, and so it's pretty slow.

• MCL is a freeware command-line-only version of Macintosh Common LISP, which runs under MacOS X nicely. It is much faster than clisp on the Mac, but its debugging facilities are primitive.

• CCL, or clozure Cl, was a fork of MCL way back when but now is a high-performance lisp implementation in its own right, and runs on a lot of different platforms. if you're getting annoyed at sbcl's verbosity, try CCL.

• Cmucl is a first-rate Common LISP, but it is not available on all platforms. cmucl is the system from which sbcl sprang.

• If you're interested in playing around with it, abcl is a Common Lisp implementation which runs on the Java VM. Note that it's not particle fast (yet ).

Sbcl is recommended here. Let's take a look... I have two, one sbcl and one clisp.

In Linux, it is detected that sbcl is installed in advance,

[email protected]:~$ which sbcl/usr/bin/sbcl

If Not Installed

sudo apt-get install sbcl

First lisp program, you must have guessed it.

Edit in current folder

Vim./Hello. LISP

(princ "hello world!")

Then enter sbcl

[Email protected]: ~ $ Vim./Hello. LISP
[Email protected]: ~ $ Sbcl
This is sbcl 1.1.1.0.debian, an implementation of ANSI Common Lisp.
