-Node: filesystem structure
-
-#. Each file/folder is represented by exactly one node.
-
-#. Some potential class properties are stored on :py:class:`waflib.Build.BuildContext` : nodes to depend on, etc.
- Unused class members can increase the `.wafpickle` file size sensibly.
-
-#. Node objects should never be created directly, use
- the methods :py:func:`Node.make_node` or :py:func:`Node.find_node` for the low-level operations
-
-#. The methods :py:func:`Node.find_resource`, :py:func:`Node.find_dir` :py:func:`Node.find_or_declare` must be
- used when a build context is present
-
-#. Each instance of :py:class:`waflib.Context.Context` has a unique :py:class:`Node` subclass required for serialization.
- (:py:class:`waflib.Node.Nod3`, see the :py:class:`waflib.Context.Context` initializer). A reference to the context
- owning a node is held as *self.ctx*

- Finds files across folders and returns Node objects:
-
- * ``**/*`` find all files recursively
- * ``**/*.class`` find all files ending by .class
- * ``..`` find files having two dot characters
-
- For example::
-
- def configure(cfg):
- # find all .cpp files
- cfg.path.ant_glob('**/*.cpp')
- # find particular files from the root filesystem (can be slow)
- cfg.root.ant_glob('etc/*.txt')
- # simple exclusion rule example
- cfg.path.ant_glob('*.c*', excl=['*.c'], src=True, dir=False)
-
- For more information about the patterns, consult http://ant.apache.org/manual/dirtasks.html
- Please remember that the '..' sequence does not represent the parent directory::
-
- def configure(cfg):
- cfg.path.ant_glob('../*.h') # incorrect
- cfg.path.parent.ant_glob('*.h') # correct
-
- The Node structure is itself a filesystem cache, so certain precautions must
- be taken while matching files in the build or installation phases.
- Nodes objects that do have a corresponding file or folder are garbage-collected by default.
- This garbage collection is usually required to prevent returning files that do not
- exist anymore. Yet, this may also remove Node objects of files that are yet-to-be built.
-
- This typically happens when trying to match files in the build directory,
- but there are also cases when files are created in the source directory.
- Run ``waf -v`` to display any warnings, and try consider passing ``remove=False``
- when matching files in the build directory.
-
- Since ant_glob can traverse both source and build folders, it is a best practice
- to call this method only from the most specific build node::
-
- def build(bld):
- # traverses the build directory, may need ``remove=False``:
- bld.path.ant_glob('project/dir/**/*.h')
- # better, no accidental build directory traversal:
- bld.path.find_node('project/dir').ant_glob('**/*.h') # best
-
- In addition, files and folders are listed immediately. When matching files in the
- build folders, consider passing ``generator=True`` so that the generator object
- returned can defer computation to a later stage. For example::
-
- def build(bld):
- bld(rule='tar xvf ${SRC}', source='arch.tar')
- bld.add_group()
- gen = bld.bldnode.ant_glob("*.h", generator=True, remove=True)
- # files will be listed only after the arch.tar is unpacked
- bld(rule='ls ${SRC}', source=gen, name='XYZ')
