I agree that mixing template haskell with -prof can be tricky. It's easier
if you turn off dynamic linking entirely.
As for multi-line string literals, I also think that an explicit syntax
would be nice. Until then, I usually use:
unlines
[ "Line 1"
, "Line 2"
]
which ends up being pretty maintainable and easy to read.

I ran into trouble compiling template haskell with -prof, and came across the ghc manual "7.9.4. Using Template Haskell with Profiling". Unfortunately I can't use its advice directly since I put profiling and non-profiling .o files into different directories. But in principle it seems it should work, I just have to get ghc to load TH from the debug build directory, which is built with -dynamic, while continuing to load from the profile build directory.
But are there flags to get it to do that? I'm using "-osuf .hs.o -ibuild/profile/obj". If I put ":build/debug/obj" on the -i line, it still seems to find the profiling one. The ghc manual advice probably gets around it by using different -osufs... I guess TH somehow ignores -osuf? Except when I compile the debug version with osuf, if finds them fine, so I don't really know how it works.
Is there a way I can directly tell TH where to look? It seems awkward to rely on all these implicit and seemingly undocumented heuristics.
And, this is somewhat beside the point, but shouldn't TH theoretically be able to load directly from .hs and compile to bytecode like ghci can do if it doesn't find the .o file?
And, even more beside the point, the only reason I'm messing with TH is for a really simple (one line) multi-line string literal quasiquote. Surely I'm not the only person who would enjoy a -XMultiLineStringLiteral extension? The alternative seems to be a program to add or strip all of the "\n\"s, and when I want to edit, copy out, strip, edit, paste back in, add back. At that point maybe it's easier to just get used to all the \s... but then indentation is all a bit off due to the leading \. _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
