Changed auto to enum for the built-in table since it never changes, right? Now smtp 25 (no proto) breaks dub build, error ends at stderr writeln not usable at compile time. ci.sh with ldc2 can't find services.txt either. Related?
enum builtin = parseServices(import("services.txt"));dns 53 udp
smtp 25ldc2 -O source/app.d -of=svcmapdub.sdl has stringImportPaths ".".
yeah, enum is fine for a table that never changes. but it forces ctfe, so every path through parseServices has to run at compile time. the smtp 25 line hits your error branch, and stderr.writeln can't run there.
throw an Exception or assert(0, msg) instead. the compiler prints the message as the build error, which is what you want.
ci.sh is separate. ldc2 needs -J. for import(). dub passes that from stringImportPaths, plain ldc2 doesn't.
i keep a parse proc like this with throw only, no io. makes ctfe painless.
Seems pothos has it covered. For ci.sh, just add -J. to the ldc2 line (the docs for -J are in the LDC command-line reference: https://wiki.dlang.org/Using_LDC). Easy fix!
