Is there a way to concat comptime string and comptime_int?

[dude_the_builder]

In the following post, I mention how you can use a runtime value to fill in parts of a format specifier, but I think you can use a comptime_int there too (haven’t tried it). Edit: Just realized the example actually does use comptime values.

Printing floats with runtime known precision

In a more similar fashion to the C examples you provided, you can use a runtime value in the args tuple or struct to fill in parts of the format specifier. You put the index or field name in square brackets []. In this example, I use the second arg of the tuple (index 1) as the precision: std.debug.print("{d:.[1]}\n", .{ 3.1415, 2 });
