def lsst.sconsUtils.utils.libraryLoaderEnvironment | ( | ) |
Returns library loader path environment string to be prepended to external commands Will be "" if nothing is required.
If we have an OS X with System Integrity Protection enabled or similar we need to pass through both DYLD_LIBRARY_PATH and LSST_LIBRARY_PATH to the external command. DYLD_LIBRARY_PATH for Python code LSST_LIBRARY_PATH for shell scripts
If both are already defined then pass them each through If only one is defined, then set both to the defined env variable If neither is defined then pass through nothing.

A Python decorator that injects functions into a class.
For example:
...will cause test_method to appear as as if it were defined within test_class.
The function or method will still be added to the module scope as well, replacing any existing module-scope function with that name; this appears to be unavoidable.

Returns True if the shebang lines of executables should be rewritten.
def lsst.sconsUtils.utils.runExternal | ( | cmd, | |

) |
Safe wrapper for running external programs, reading stdout, and sanitizing error messages.
Command can be given as a list/tuple of command with separate options.
Note that the entire program output is returned, not just a single line.

def lsst.sconsUtils.utils.whichPython | ( | ) |
Returns the full path to the Python executable as determined from the PATH.
Does not return the full path of the Python running SCons. Caches result and assumes the PATH does not change between calls. Runs the "python" command and asks where it is rather than scanning the PATH.
