I have a test block that is failing.
How can I add debug prints?
std.debug.print doesn't work, it's just skipped.
@compileLog is helpful to figure out what branches I am going in, but I cannot print some values since they are deemed runtime values.
Trying to add prints to see where changes to this code fails https://github.com/ZigEmbeddedGroup/microzig/blob/main/port/raspberrypi/rp2xxx/src/hal/pio/assembler/comparison_tests.zig#L167
specifically I am trying to print the value of certain tokens in the tokenizer. I can add compile logs to see which branches are being taken, but I cannot print a token because it says its a runtime value
if (cpu == .RP2350 and std.mem.startsWith(u8, peek_source_lower.slice(), "rxfifo")) {
@compileLog("got mov from rx?", peek_source_lower.slice()); // DELETEME
@compileError("wtf");
}```
the branch is entered based on a runtime value (peek_source_lower), so why can't I log its value?

is there a reason youre using @compileLog instead of std.debug.print?
rigid axle
std.debug.print isn't showing up in the output
devout idol
then its probably not getting called
rigid axle
but i am seeing the compile logs
devout idol
yeah because compile logs get called in runtime ifs no matter the condition
rigid axle
can I make the prints work even if the tests pass?
devout idol
what tests
rigid axle
I am running zig build test, the linked test is failing (with changes locally)
if (cpu == .RP2350 and std.mem.startsWith(u8, peek_source_lower.slice(), "rxfifo")) {
// @compileLog("got mov from rx?", peek_source_lower.slice()); // DELETEME
// std.debug.panic("wtf", .{});
std.debug.print("XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX hello {s}\n", .{peek_source_lower.slice()});
return error.Fuck;
I see the error but not the log
one sec
I was also getting this

the test function pio_comparison's only argument is comptime https://github.com/ZigEmbeddedGroup/microzig/blob/main/port/raspberrypi/rp2xxx/src/hal/pio/assembler/comparison_tests.zig#L33
which i think is where most my confusion is coming from
it calls assemble which is also comptime, and it uses compileError to complain
devout idol
hm so it is running at comptime
rigid axle
yeah, a bit strange. I guess here I am expecting to see error when compiling the test not when running the test
devout idol
```
if (cpu == .RP2350 and std.mem.startsWith(u8, peek_source_lower....
and what is the error youre getting here
rigid axle
I get a log I expect, but I can't debug it since it won't print what I need
@as(*const [16:0]u8, "got mov from rx?"), @as([]const u8, [runtime value])
I don't understand why it's a runtime value when the call is comptime
rigid axle
can't resolve comptime value
you're being generous with your time btw, I appreciate it
if you're at all willing, it's an easy repro if I push my code
but i don't expect you to clone and run anything to help me
devout idol
you're being generous with your time btw, I appreciate it
np its unfortunately ending tho gotta go but if you dont get an answer im gonna try to figure it out later
rigid axle

no sweat. I appreciate it. I'll keep at it

Could you show the erorr that you get when you use comptimePrint?

I've tried to convert the assemble function so that it can run at runtime. It would run at compile time normally (it's assembled and injected into the output binary). Unfortunately the way the tests work is it uses the compiled program name to compare it to an imported c header file, by accessing the struct field with program.name + some stuff
