I've tried using *default-pathname-defaults* before, but it always comes up as an empty string because it seems I'm not able to practically "control the directory I start Lisp in." It should be a pathname, actually, rather than a string. However, it's weird that it's empty. How do you acc...

In the Lisp universe, the counterpart of the current working directory is the *default-pathname-defaults* variable. It's similar, but better. When Lisp starts, typically it bounds *default-pathname-defaults* to the current directory. Suppose I've got directories ~/test/a & ~/test/b & a file ...

Unfortunately, this is not possible, at least not with free implementations.

Most likely, the bottleneck is the loading of external libraries, i. e. trivial-shell and cl-json. You could time your function in the REPL using the TIME function and time your script in the shell, I guess the former must take much less time than the latter. Personally, for small script-like progra...

Actually you should try and use UIOP, a portable wrapper for OS-related functionality. It is a part of ASDF3 and should be available out of the box (you could also check if your *features* have ASDF3). The command would be then (uiop:run-program "unzip zipfile.zip -d destinationdir/") UIOP...

SBCL is the most active free implementation, and a very efficient one. You could also try CLISP or CCL. As an IDE I use vim + slimv, but the vast majority chooses Emacs + Slime. The way you put it, your library should work with any implementation. The function LOAD loads specified lisp file executin...

I wonder if there's a way to customize indentation in slimv. First of all, it doesn't handle DO properly (the second pair of parentheses must be indented as the first one). Another issue: although I can do :set lispwords-=if and thus properly indent IF, I don't know how to obtain the same effect wit...

It has been ported to Windows. One can even install LispBox and not care about Emacs settings or Lisp implementations (since one is included).

Other options are vim + slimv and perhaps able.

Why not use Emacs with CLISP?

What do you mean by `producing result'? You could try to build any open source project...

As for the listvariable, there's obviously no way to use it: http://permalink.gmane.org/gmane.lisp.ltk.user/494 However, it's not hard to implement mutatis mutandis : (defclass tklistvariable ()) (defmethod initialize-instance :around ((v tklistvariable) &key) (call-next-method) (format-wish &qu...
