[Hugs] #61: [Patch] Readline command completion for everything

#61: [Patch] Readline command completion for everything -------------------------+-------------------------------------------------- Reporter: gsauthof | Owner: nobody Type: enhancement | Status: new Priority: major | Milestone: Component: hugs | Version: 200609 Keywords: | -------------------------+-------------------------------------------------- Hi, I wrote a patch that improves the readline command completion feature of hugs. I.e: - added completion of function names and constructors - added completion of command names (:<cmd>) - added completion of module names (e.g. after :browse , etc.) - only do filename completion where it makes sense (e.g. after :load , etc.) - expand use of tilde (~) in filenames (previously it was completed but not recognized by hugs) - read and write the history from/to ~/.hugs_history - make hugs recognize :help Patch is attached.

System.Directory.getTemporaryDirectory broken on Windows
by Neil Mitchell 31 Mar '07

31 Mar '07

Hi, getTemporaryDirectory is defined as: getTemporaryDirectory :: IO FilePath getTemporaryDirectory = do #if defined(mingw32_HOST_OS) allocaBytes long_path_size $ \pPath -> do r <- c_GetTempPath (fromIntegral long_path_size) pPath peekCString pPath #else catch (getEnv "TMPDIR") (\ex -> return "/tmp") #endif However, taking a look at the generated files that ship with WinHugs Sep 2006, the code is the #else case - a catch and TMPDIR. This means that function doesn't work on Windows properly Any idea how this happened? I will try recompiling the libraries after Easter. Should mingw32_HOST_OS be defined with our build system on Windows? Thanks Neil

[Hugs] #51: The WinHugs uninstaller.exe doesn't work!

#51: The WinHugs uninstaller.exe doesn't work! -----------------------------+---------------------------------------------- Reporter: guest | Owner: neil Type: defect | Status: new Priority: major | Milestone: Component: winhugs | Version: current Keywords: setup uninstall | -----------------------------+---------------------------------------------- Hi guys! I was trying to uninstall WinHugs in order to install a newer version, and I found that the uninstaller.exe program doesn't work. I opened the uninstaller.exe with a hex editor, and I found that it's not a valid executable file. It's some weird combination of HTML and executable code. These are the first 15 lines of the uninstaller.exe file: {{{ <html> <head> <META HTTP-EQUIV="Content-Type" content="text/html; charset=Windows-1252"> </head> <body> <pre> <table width=100% bgcolor=#CFCFE5><tr> <td> <font face=arial size=+3> Build Log </font></table><table width=* cellspacing=0 cellpadding=0><tr><td width=0 bgcolor=#EDEDF5> </td><td width=0 bgcolor=#FFFFFF> </td><td width=*><pre> <h3>------- Build started: Project: Uninstaller, Configuration: Release|Win32 ------- </h3> </pre></table><table width=100% bgcolor=#DFDFE5><tr><td><font face=arial size=+2> Command Lines </font></table><table width=* cellspacing=0 cellpadding=0><tr><td width=0 bgcolor=#EDEDF5> </td><td width=0 bgcolor=#FFFFFF> </td><td width=*><pre>Uninstaller - up-to-date.</pre></table><table width=100% height=20 bgcolor=#CFCFE5><tr><td><font face=arial size=+2> </font></table></body></html> }}} I hope this is not difficult to fix.

0/0 => "nan", not "NaN". Also, empty hsc2hs dir and "invalid predicate `-wholename'"
by Ian Lynagh 23 Mar '07

23 Mar '07

Hi all, hugs thinks that show (0/0 :: Double) is "nan", but it will only read "NaN". I'd suggest changing the behaviour of show rather than that of read, so as to match GHC: Prelude> show (0/0 :: Double) "NaN" Prelude> read "nan" :: Double *** Exception: Prelude.read: no parse Prelude> read "NaN" :: Double NaN The result of the show seeme to come from sprintf in doubleToString (src/machdep.c); this C program also prints "nan": #include <stdio.h> int main(void) { char b[100]; sprintf(b, "%e", (double) 0/0); printf("%s\n", b); return 0; } While building CVS/darcs hugs I got darcs get --partial http://darcs.haskell.org/hsc2hs Directory '/home/ian/code/hugs/hugs98/hsc2hs' already exists, creating repository as '/home/ian/code/hugs/hugs98/hsc2hs_0' I think due to an empty CVS directory; I had to jiggle them around for it to build later on. I also got /usr/bin/find: invalid predicate `-wholename' thrice. Replacing -wholename with -path in libraries/tools/make_bootlib let the build go through, but I'm not sure if this is either (a) correct or (b) a superset of the portability of -wholename. Thanks Ian

copyFile on Windows dies with binary files
by Neil Mitchell 22 Mar '07

22 Mar '07

Hi, copyFile on Windows with a binary file doesn't work terribly well - it truncates at the first binary zero. The code goes: copyFile :: FilePath -> FilePath -> IO () copyFile fromFPath toFPath = do readFile fromFPath >>= writeFile toFPath try (copyPermissions fromFPath toFPath) return () That should be openFileBinary etc. Thanks Neil
