Re: [Haskell-cafe] Mascot Poll Results
-1 (no mascot). As a amusing as a slacker dude might be, out doesn't send the right message.There's a reason why RMS isn't the mascot for FSF, for example.

Re: [Haskell-cafe] How to get a file path to the program invoked?
It's not a poor practice at all. Example: gcc, which uses the executable's path as the base directory from which other files are located. MacOS also does something similar. -Original message- From: Paul R To: dokondr Cc: Simon Hengel , haskell-cafe Sent: Sun, Dec 4, 2011 15:26:28 PST Subject: Re: [Haskell-cafe] How to get a file path to the program invoked? dokondr> On the contrary, standard shell variable $0 - contains a full dokondr> path to the program location in the directory structure, no dokondr> matter from what directory the program was called. I don't think the comparison makes sense, as shell script invocation and executable run are very different mechanisms. Whenever you invoke a shell script, what really happens is that a program in your path (sh, bash ...) gets started with an argument that is the path to the script to load (your script actually). In this situation, you understand that it is easy to provide the path to the script (the $0) : it is just the file that the interpreter is loading. I don't know if it is possible at all to get this information in the context of binary execution. And I'm not sure it is a good practice anyway :) -- Paul ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

That's true even for regular fork/exec. -Original message- From: Richard O'Keefe To: wren ng thornton Cc: haskell-cafe Sent: Sun, Dec 4, 2011 15:54:15 PST Subject: Re: [Haskell-cafe] How to get a file path to the program invoked?

It's not at all straightforward to determine the actual location of the executable, especially not in a platform-independent manner. argv[0] can't be trusted, scanning through $PATH isn't guaranteed to find it (and even if you find something of the right name, it's not guaranteed to be the correct executable), etc etc. In particular, with posix_spawnp(), the $PATH that is used to find the executable and the $PATH in the environment that the executable starts with can be two different things. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
Re: [Haskell-cafe] If you'd design a Haskell-like language, what would you do different?
I'd suggest, in addition to the symbols, renaming some of the fundamental types and concepts, like Monad. I would violently agree that Monad is the correct term, but try to communicate with a commodity software developer sometime (or a government acquisition professional). RWH goes a long way to explaining the concepts, as do the countless Web pages dedicated to explaining the monad concept. Better examples for SYB and arrows would also help. Haskell is a great language with solid mathematical underpinnings. I'm a big fan of it. But, adoption is the key to success; need to make the ordinary easy to understand unless the community wants to be relegated to Scala status. -Original message- From: Andrew Cowie To: haskell-cafe@haskell.org Sent: Tue, Dec 20, 2011 18:05:18 PST Subject: Re: [Haskell-cafe] If you'd design a Haskell-like language, what would you do different?
