emacs – 学习Windows / C程序员的常见Lisp技巧

-I get the REPL,but don’t quite get how I can use it effectively. When I
need to change a function I have to
retype the defun and make changes
(tedious and error prone). How can I
do this better?

-How do I get from entering code at the REPL to actually having a program?
I’m used to the C model where you have
code files that you can review,edit
and recompile. I know lisp has
something similar (via the load
function),but how does one get a
function I just defined and tested
into a file to be saved? I’m hoping
there’s a better method than my
current select+copy+paste.

加载SLIME.在.lisp文件中输入代码,然后运行slime-eval-buffer将所有代码加载到Lisp中.然后,对于一个特定的函数,你正在攻击C-e,C-j在你运行的Lisp中重新定义它.

-How do you debug errors? Is there any ability to step into code like I would with other languages?

是. (跟踪’my-function) – 或其中的一些变体 – 当调用my-function时,它将进入调试器.

-As long as the S-expression is valid,I don’t get any errors when entering a
(defun …). It’s not until I try to
use it that I find out it’s not valid.
Is there any way to get errors sooner
(i.e. compile the code)?

在某种程度上,这是动态语言(Python,Perl,Ruby,Lisp等)的特征.尝试SBCL以获得更好的错误检查.

-Is there some IDE that would be more familiar to me or allow me to play with the language easier?

Emacs是Lisp的免费IDE. Allegro有一个免费版我相信;我从来没试过过..

-Should I switch to learning Scheme instead?

不,Scheme不是一种实用的语言.
