Package SCons :: Package Node :: Module FS

Module FS

scons.Node.FS

File system nodes.

These Nodes represent the canonical external objects that people think of when they think of building software: files and directories.

This holds a "default_fs" variable that should be initialized with an FS that can be used by scripts or modules looking for the canonical default.

Classes

EntryProxyAttributeError
An AttributeError subclass for recording and displaying the name of the underlying Entry involved in an AttributeError exception.

_Null

DiskChecker

EntryProxy

Base
A generic class for file system entries. This class is for when we don't know yet whether the entry being looked up is a file or a directory. Instances of this class can morph into either Dir or File objects by a later, more precise lookup.

Entry
This is the class for generic Node.FS entries--that is, things that could be a File or a Dir, but we're just not sure yet. Consequently, the methods in this class really exist just to transform their associated object into the right class when the time comes, and then call the same-named method in the transformed class.

_classEntry
This is the class for generic Node.FS entries--that is, things that could be a File or a Dir, but we're just not sure yet. Consequently, the methods in this class really exist just to transform their associated object into the right class when the time comes, and then call the same-named method in the transformed class.

LocalFS

DirNodeInfo
The generic base class for signature information for a Node.

DirBuildInfo
The generic base class for build information for a Node.

Dir
A class for directories in a file system.

RootDir
A class for the root directory of a file system.

FileNodeInfo
The generic base class for signature information for a Node.

FileBuildInfo
The generic base class for build information for a Node.

File
A class for files in a file system.

invalidate_node_memos(targets)
Invalidate the memoized values of all Nodes (files or directories) that are associated with the given entries. Has been added to clear the cache of nodes affected by a direct execution of an action (e.g. Delete/Copy/Chmod). Existing Node caches become inconsistent if the action is run through Execute(). The argument targets can be a single Node object or filename, or a sequence of Nodes/filenames. source code

find_file(filename, paths, verbose=None)

source code


find_file(str, [Dir()]) -> [nodes]

filename - a filename to find
paths - a list of directory path *nodes* to search in.  Can be
        represented as a list, a tuple, or a callable that is
        called with no arguments and returns the list or tuple.

returns - the node created from the found file.

Find a node corresponding to either a derived file or a file
that exists already.

Only the first file found is returned, and none is returned
if no file is found.
