ansi-terminal's Issues

exception when using inside Notepad++ embedded console

Hi, Max!

I'm trying to use Notepad++ as my IDE for Haskell. And I'm having problems with ansi-terminal working within the console window that Notepad++ provides. I'm getting
* Exception: getConsoleScreenBufferInfo: invalid argument (* Exception: : hPutChar: invalid argument (invalid character)

I didn't use much of ansi-terminal API yet, just clearScreen and setCursorPosition for now.

Sorry if all these have an obvious resolution, I'm new to Haskell. And don't hesitate to ask if you need any details to fix this

Linking msvcrt into mingw programs is not supported.

Since GHC is using mingw on windows, it is incorrect to also link msvcrt into the same executable. This in theory could cause problems for haskell programs as well, but it certainly breaks hsc2hs: if a program depends on ansi-terminal, using hsc2hs in such a program will make it unbuildable. The executables generated by hsc2hs will link msvcrt (due to ansi-terminal) and segfault on startup (since they are compiled with mingw and linking the mingw runtime). This makes darcs unbuildable on windows if you enable testing (i.e. we can't run tests due to this problem).

Missing C library: kernel32

Hi Max,

Sorry if this is something well-understood, but my Google-fu fails me. I received a support request from somebody trying to use my program GenI, which depends on test-framework and consequently ansi-terminal.

What they said follows. Any advice about debugging steps I could ask them to do? I don't know enough about Windows to know what to say.

---

 $ cabal install GenI

 Configuring ansi-terminal-0.5.5...
 cabal.exe: Missing dependency on a foreign library:
 * Missing C library: kernel32
 This problem can usually be solved by installing the system package that
 provides this library (you may need the "-dev" version). If the library is
 already installed but in a non-standard location then you can use the flags
 --extra-include-dirs= and --extra-lib-dirs= to specify where it is.
 cabal.exe: Error: some packages failed to install:
 GenI-0.20.2 depends on ansi-terminal-0.5.5 which failed to install.
 ansi-terminal-0.5.5 failed during the configure step. The exception was:
 ExitFailure 1
 ansi-wl-pprint-0.6.3 depends on ansi-terminal-0.5.5 which failed to install.
 test-framework-0.2.4 depends on ansi-terminal-0.5.5 which failed to install.
 test-framework-hunit-0.2.6 depends on ansi-terminal-0.5.5 which failed to
 install.
 test-framework-quickcheck-0.2.7 depends on ansi-terminal-0.5.5 which failed to
 install.

This dll is very much there in C:\Windows\System32 and I also tried giving its path in --extra-include-dirs and --extra-lib-dirs but it still didn't work.

Allow more colours?

Hi, I am just wondering why this package only support limited colours? Thanks 😄

getConsoleCursorInfo exception w/ hideCursor on Windows

This bug seems to only occur in some relatively specific circumstances -- we've been able to reproduce it reliably by ssh-ing into a cygwin shell running on windows:

Reproduction:

• ssh into a cygwin ssh server running on windows (32-bit XP, 32-bit Vista and 64-bit Vista all exhibit this problem, we haven't tested others.)
• start up ghci (ghcii.sh -- 6.10.4 and 6.12.1 both exhibit the bug, haven't tested others.)
• load the System.Console.ANSI module: (:m + System.Console.ANSI)
• invoke hideCursor. This should result in: *** Exception: getConsoleCursorInfo: invalid argument (The handle is invalid.)

This happens as either an unprivileged user or as administrator, so we do not believe it is related to the cygwin bug discussed here, although the reproduction is similar. (This bug also pre-dated cygwin 1.7.) This bug does not happen when logged in directly to a windows system, although you can ssh to localhost to reproduce it.

This came up because it prevents test-framework from running on windows build slaves that are activated via ssh-ing into a cygwin server. (even using --plain to reduce the test-framework output is insufficient, since the cursor is still hidden.) I think hideCursor (and other functions that may trigger this bug) should return error values instead of throwing exceptions.

Here's a complete log of a ghci session that triggers the bug:
