1 IntroductionLisp is the second oldest language in the world, and the first ancient language is FORTRAN. The founder of the Lisp language is John McCarthy, a pioneer in the field of artificial intelligence. Since its inception, the language has gone through more than 50 years and is a very vigorous language. The development and use of the language is inseparable from the two universities of CMU and MIT, which have been the designated language of the
I 've been procrastinating, playing with Lisp, but I can't solve this problem after all. In this case, I started to shake my mind.
The author first complained and compared the differences between lisp macros and other languages. Formally speaking, the so-called standard macros are the same as class libraries such as c and java, it is the stuff that has been completed and verified in advance and encapsulated

: drawing file. You can create a drawing file before creating a symbol, and then compiled it into a binary symbol file.. PSM: Package symbol, solid packaging part.. OSM: Format symbol, parts for manufacturing, assembly, and logo graphics.. SSM: Shape symbol, used in the padstack designer to customize the geometric shape of the pad.. BSM: Mechanical symbol, which has no electrical characteristics.. FSM: the connection method of Flash symbol and negative-part guide through-hole.. MDD: module, whic
These days began to play common Lisp, encountered an interesting problem, CL is generally interpreted to run, there are implementations can compile generated bytecode (FAS file). The two CL implementations I'm using are SBCL and clisp, which I see in the book "Practical Common Lisp programming," one of the features of

The first time you use a setf assignment for a symbol (not defined as a local variable), the symbol is used by the system as a global variable. This is a method of implicitly defining global variables, but it is not worth advocating.> (setf *var* 1234)>1234Ii. Input and output(1)
In Win32 GNU Common Lisp development environment, after GNU Common Lisp is installed in Win32 environment, a shortcut is generated in the Start menu to view its attributes,The start position is blank. After the shortcut is copied to any directory for running, the running directory will be used as the current path. I cr
After so many years of development, LISP has evolved many dialects, including Common LISP, schema, and Emacs lisp. Select a "general" learning method first.

Today, I am in a high mood, because I decided to end the Common Lisp in one of my learning plans. Now I can go to the next learning plan! I have been studying lisp for nearly a year since I read the book "hacker and painter", and I have been very busy working in this year, learning "Practical C
