Hi

I found a function which shows the current working directory on
http://www.newlisp.org/index.cgi?page=Code_Snippets
which is very handy

Is there a function which is similar to the Tcl glob function?
http://tmml.sourceforge.net/doc/tcl/glob.html

I would like to say

Code: Select all

(glob "*.txt")

and get back a list of all file names in the current working directory matching the pattern.
Perhaps somebody already has implemented something like this?

Thanks for the answer in advance.

Use 'filter' to filter out the files you want

Code: Select all

> (filter (fn (f) (ends-with f ".c")) (directory))
("newlisp.c" "nl-count.c" "nl-debug.c" "nl-filesys.c" "nl-import.c" 
 "nl-list.c" "nl-liststr.c" "nl-math.c" "nl-matrix.c" "nl-sock.c" 
 "nl-string.c" "nl-symbol.c" "nl-utf8.c" "nl-web.c" "nl-xml.c" "osx-dlfcn.c" 
 "pcre-chartables.c" "pcre.c" "sql.c" "tru64.c" "types.c" "unix-lib.c" 
 "win32-util.c" "win32dll.c")

or on UNIX, this gives you the same:

Code: Select all

(exec "ls *.c")

I don't have a Windows machine close, but I think:

Code: Select all

(exec "dir /b")

would work, or may be you would have to call the shell:

Code: Select all

(exec "cmd /c dir /b")
