Should `system-index.txt` be ignored?

[daninus14]

I find that by doing qlot install I get git differences in system-index.txt every time. Is this expected? Should it be ignored?

One machine is a mac and the other ubuntu, pulling the same repo and doing qlot install yields a different system-index.txt.

For context: this system-index.txt is in the root directory of the project which also contains the .qlot/ directory and the qlfile.

It is not supposed to be created. Is the directory added to Quicklisp's local projects? Please write reproducible steps.

Oh, maybe I messed up my setup?

I have the project in a non quicklisp folder, just in a personal folder, and I load the project in the REPL (slime) by:

(pushnew 
 (truename "/home/mydir")
 ql:*local-project-directories*)

And then in the REPL again I can do

(ql:quickload "mydir")

Assuming mydir above is the name of the system defined in that directory.

I'm pretty sure I did something like qlot init in the folder originally, and then added systems by using qlot install or in the REPL doing (ql:quickload "system-name").

I start the repl with qlot exec ros run or something of that sort so that the quicklisp loaded should be the one from qlot.

By the way, now that you enabled discussions, should I move this over there?

That's the thing. Quicklisp makes system-index.txt for local projects to cache system names to load them quickly.

Ah this is fantastic, I just realized qlot was already adding my main folder by doing qlot exec ros run, so I basically can just do (ql:quickload "myproject") without adding it. I didn't know. I had that from before I was using qlot. Thanks for the help 😄
