newlisp main-args not to execute

Post by dexter »

I recently met a "problem"

I wrote a newlisp file ,let's say, test1.lsp

then I want the test1.lsp to deal with files in the (main-args) , like

Code: Select all

newlisp test1.lsp xxxx.file
In my mind, I thought newlisp and test1.lsp are together like one binary file
but then I found out , the command "newlisp" will also try to run xxxx.file whatever it is,just a file

I think there is no method can stop this behavior ,right?

so maybe newlisp can have a command line argument,like -f ? to seprate the files need to be executed or just use them as "string argments" ?

Just add the (exit) command to the end of your test1.lsp file to prevent the further loading of files as code...

This feature is so that any modules (that don't have the exit command) can be loaded ahead of your final code file...

I generally just use the #! syntax

Code: Select all

$ cat foo.lsp
#!/usr/bin/newlisp

(println (main-args))
(exit)

$ chmod 755 foo.lsp    # make sure foo.lsp is executable
$ ./foo.lsp xxxx.file
("/usr/bin/newlisp" "./foo.lsp" "xxxx.file")
Hope this helps.

Use (reset) at the end of the script rather than (exit) If you want to enter interactive mode at that point.
