I am trying to store list of files from directory in variable (using only CLI, Red version: 0.6.3).

I tested couple of functions from "Red by example" documentation, but all of them give me only an CLI output with list of elements from directory:

When I tried save it into variable, I've got an errors like:

>> var: list-dir %tests
    other-tests.red         README.md               poc-tests.red      
*** Script Error: var: needs a value
*** Where: var
*** Stack: 

>> files: ls tests
other-tests.red         README.md               poc-tests.red       
*** Script Error: files: needs a value
*** Where: files
*** Stack:  

>> other: dir %tests
other-tests.red         README.md               poc-tests.red       
*** Script Error: other: needs a value
*** Where: other
*** Stack:

I also found the call method, which give me possibility to run external scripts (like shell scripts), and by that I can execute OS command ls:

>> filelist: ""
>> call/output "ls tests" filelist
>> print filelist
other-tests.red
poc-tests.red
README.md

But this solution is dependent on the operating system. For example in MS Windows call/output "dir tests" filelist will work.

Can anyone tell me - is there another solution for that using pure Red code without executing external scripts?

Maybe somewhere there are some magic functions from Red System, whose will give us that?

That's would be great to be independent of OS.

Thanks for the answers

All that's required is a READ of the directory:

read %tests/

This will give you a block of FILE! values for the contents of the directory.

  • Wow, it works. Earlier I was trying to execute `read %tests`, but without `/` sign. Thanks to your advice I have whole problem resolved. Thanks! – Mateusz Palichleb Feb 14 '18 at 09:43
