# wmlscope -- generate reports on WML macro and resource usage
|
|
#
|
|
# By Eric S. Raymond, April 2007.
|
|
#
|
|
# This tool cross-references macro definitions with macro calls, and
|
|
# resource (sound or image) files with uses of the resources in WML.
|
|
# and generates various useful reports from such cross-references.
|
|
#
|
|
# It takes a list of directories as arguments; if none is given, it
|
|
# behaves as though the current directory had been specified as a
|
|
# single argument. Each directory is treated as a separate domain for
|
|
# macro and resource visibility purposes, except that macros and resources
|
|
# under the first directory are made visible in all later ones. (Typically
|
|
# the first directory should point at a copy of mainline and all later
|
|
# ones at UMC.)
|
|
#
|
|
# The checking done by this tool has a couple of flaws:
|
|
#
|
|
# (1) It doesn't actually evaluate file inclusions. Instead, any
|
|
# macro definition satisfies any macro call made under the same
|
|
# directory. Exception: when an #undef is detected, the macro is
|
|
# tagged local and not visible outside the span of lines where it's
|
|
# defined.
|
|
#
|
|
# (2) It doesn't read [binary_path] tags, as this would require
|
|
# implementing a WML parser. Instead, it assumes that a resource-file
|
|
# reference can be satisfied by any matching image file from anywhere
|
|
# in the same directory it came from. The resources under the *first*
|
|
# directory argument (only) are visible everywhere.
|
|
#
|
|
# (3) A reference with embedded {}s in a macro will have the macro's
|
|
# formal args substituted in at WML evaluation time. Instead, this
|
|
# tool treats each {} as a .* wildcard and considers the reference to
|
|
# match *every* resource filename that matches that pattern. Under
|
|
# appropriate circumstances this might report a resource filename
|
|
# statically matching the pattern as having been referenced even
|
|
# though none of the actual macro calls would actually generate it.
|
|
#
|
|
# (4) There are some implicit references. Notably, if an attack name
|
|
# is specified but no icon is given, the attack icon will default to
|
|
# a name generated from the attack name,
|
|
#
|
|
# Problems (1) and (2) imply that this tool might conceivably report
|
|
# that a reference has been satisfied when under actual
|
|
# WML-interpreter rules it has not. Problem (4) means the reverse
|
|
# can also occur.
|
|
#
|
|
# The reporting format is compatible with GNU Emacs compile mode.
