I thought I did?-) or is this list deprecated in favour of sourceforge? >Strange - command prompt windows should be nice and large and >scrollable, mine are at least. Cut-and-paste support is terrible, though. oh, they are, just not in windows 98. but c&p works even there. >Works for me! Remember that System.system is executing CMD.EXE, not >Cygwin bash, so it'll probably have a different PATH and might not be >able to find your Cygwin binaries. Both System.system "dir", and >System.system "c:/cygwin/bin/ls" work for me. System.system used to pick up the current PATH from the cygwin environment, which is a lot more comfortable. But as I mentioned, it makes no difference if I use ghci directly, and try pure and absolute windows paths, or "dir" - it seems as if it doesn't matter at all what command it is, nothing gets through. See also the ":!<cmd>" issue, for which, I assume, ghci uses System.system internally. >Perhaps rawSystem is using the current PATH setting, which it inherited >from the bash shell, whereas System.system is starting a new CMD.EXE >which resets the PATH? Try System.system "set PATH". can't, see above. but that would be (a) counterintuitive behaviour, and (b) a change from previous incarnations of System.system, IIRC. It is good that at least one of the two works, and better than before in terms of ExitCode, but .. WAIT A SEC, CMD.EXE ON WIN98??? ah yes, one should read error messages, I guess (see previous emails), under bash: Prelude> let system c = System.Cmd.rawSystem "bash" ["-c",c] Prelude> system "pwd" /home/unknown Prelude> system "true" >>= print ExitSuccess Prelude> system "false" >>= print ExitFailure 1 Prelude> let systemC c = System.Cmd.rawSystem "command.com" ["/c",c] Prelude> systemC "cd" Angegebenes COMMAND-Verzeichnis ist falsch Befehl oder Dateiname nicht gefunden. Prelude> let systemC c = System.Cmd.rawSystem "command.com" ["/c "++c] Prelude> systemC "cd" Angegebenes COMMAND-Verzeichnis ist falsch D:\cygwin\home\unknown I can't quite figure out how to pass the "/c" option to command.com (it looks as if rawSystem passes some junk *in addition to* the parameters, which confuses command.com, and apparently option and parameter count as *a single* parameter to rawSystem), but this is a lot better than what System.system and ":!" do. It seems that someone dropped a windows 98 dependency when reimplementing System.system?-) Prelude> System.Cmd.rawSystem "echo" ["/c","cd"] /c cd hmm, no visible junk there, so perhaps the "/c" is interpreted as the path parameter instead of/as well as an option. over to you.
