Package SCons :: Module Defaults

Module Defaults

SCons.Defaults

Builders and other things for the local site. Here's where we'll duplicate the functionality of autoconf until we move it into the installation procedure or use something like qmconf.

The code that reads the registry to find MSVC components was borrowed from distutils.msvccompiler.

Classes

[hide private]

NullCmdGenerator
This is a callable class that can be used in place of other command generators if you don't want them to do anything.

Variable_Method_Caller
A class for finding a construction variable on the stack and calling one of its methods.

Functions

[hide private]

_fetch_DefaultEnvironment(*args, **kw)
Returns the already-created default construction environment.

source code

DefaultEnvironment(*args, **kw)
Initial public entry point for creating the default construction Environment.

source code

StaticObjectEmitter(target, source, env)

source code

SharedObjectEmitter(target, source, env)

source code

SharedFlagChecker(source, target, env)

source code

get_paths_str(dest)

source code

chmod_func(dest, mode)

source code

chmod_strfunc(dest, mode)

source code

copy_func(dest, src, symlinks=True)
If symlinks (is true), then a symbolic link will be shallow copied and recreated as a symbolic link; otherwise, copying a symbolic link will be equivalent to copying the symbolic link's final target regardless of symbolic link depth.

touch_func(dest)

source code

_concat(prefix, list, suffix, env, f=<__builtin__.function object>, target=None, source=None)
Creates a new list from 'list' by first interpolating each element in the list using the 'env' dictionary and then calling f on the list, and finally calling _concat_ixes to concatenate 'prefix' and 'suffix' onto each element of the list.

source code

_concat_ixes(prefix, list, suffix, env)
Creates a new list from 'list' by concatenating the 'prefix' and 'suffix' arguments onto each element of the list. A trailing space on 'prefix' or leading space on 'suffix' will cause them to be put into separate list elements rather than being concatenated.

source code

_stripixes(prefix, itms, suffix, stripprefixes, stripsuffixes, env, c=None)
This is a wrapper around _concat()/_concat_ixes() that checks for the existence of prefixes or suffixes on list items and strips them where it finds them. This is used by tools (like the GNU linker) that need to turn something like 'libfoo.a' into '-lfoo'.

source code

processDefines(defs)
process defines, resolving strings, lists, dictionaries, into a list of strings

source code

_defines(prefix, defs, suffix, env, c=<__builtin__.function object>)
A wrapper around _concat_ixes that turns a list or string into a list of C preprocessor command-line definitions.

source code

__libversionflags(env, version_var, flags_var)

Function Details

[hide private]

DefaultEnvironment(*args, **kw)

source code

Initial public entry point for creating the default construction Environment.

After creating the environment, we overwrite our name (DefaultEnvironment) with the _fetch_DefaultEnvironment() function, which more efficiently returns the initialized default construction environment without checking for its existence.

(This function still exists with its _default_check because someone else (cough Script/__init__.py cough) may keep a reference to this function. So we can't use the fully functional idiom of having the name originally be a something that only creates the construction environment and then overwrites the name.)
