System.Environment.Executable
Description
The documentation of "System.Environment.getProgName" says that
"However, this is hard-to-impossible to implement on some non-Unix OSes, so instead, for maximum portability, we just return the leafname of the program as invoked. Even then there are some differences between platforms: on Windows, for example, a program invoked as foo is probably really FOO.EXE, and that is what "getProgName" will return."
This library tries to fix this issue. It also provides some platform-specific functions (most notably getting the path of the application bundle on OSX). Supported operating systems:
- Win32 (tested on Windows 7)
- Mac OS X
- Linux
- FreeBSD (tested on FreeBSD 6.4)
- *BSD (with procfs mounted, plus fallback for certain shells; untested)
- Solaris (untested, and probably works on Solaris 10 only)

Constructors
| Executable FilePath | it was (probably) a proper compiled executable |
| RunGHC FilePath | it was a script run by runghc/runhaskell |

getScriptPath :: IO ScriptPath Source #
An experimental hack which tries to figure out if the program
was run with runghc or runhaskell or ghci, and then tries to find
out the directory of the source (or object file).
GHC only.
