zigtools / scip-zig Goto Github PK

I am new to Zig, so I imagine I'm doing something stupid here.

I installed zig and successfully built the scip-zig binary. My zig directory is at $HOME/zig.

I tried running scip-zig --pkg std $HOME/zig/lib/std/std.zig --root std and got the following error:

                ^

I also tried running scip-zig --pkg std src/scip.zig --root scip-zig and got the same error. Is there something obvious I'm missing? I'm not sure which file it's looking for. Haven't used Zig much before, just trying to generate an index and then upload to sourcegraph.com, because I think that would be pretty cool!

This would allow us to use a [4]i32 rather than a std.ArrayListUnmanaged(i32) in scip.zig's Occurrence.range which would save us a huge amount of memory!

Won't be as complete as with ZLS but will be more correct :)

The project cannot compile using the master of zig, I try to fix the compile errors, but unfortunetely it failed to run. the detail is below. it seems it is caused by the change of for range syntax .

We currently cram everything into a single file which is completely broken for things that import external packages.
