# Converts a list of atoms in the form:
|
|
# // OUTPUT_CLASS=<classname>
|
|
# // MACRO_NAME=<macro>
|
|
# <macroname>(atomName, "String")
|
|
# <macroname>(atomName2, "String2")
|
|
#
|
|
# into a file suitable for gperf using static atoms
|
|
#
|
|
# usage:
|
|
# make-atom-strings < file.h > file.gperf
|
|
#
|
|
# the lines in the C++ comments define two variables:
|
|
# OUTPUT_CLASS is the class who has all the atoms as members
|
|
# MACRO_NAME is the macro to look for in the rest of the file
|
|
#
|
|
# for example
|
|
# // OUTPUT_CLASS=nsHTMLAtoms
|
|
# // MACRO_NAME=HTML_ATOM
|
|
# HTML_ATOM(a, "a")
|
|
# HTML_ATOM(body, "body")
|
|
#
|
|
# etc...
|
|
#
|
|
# this will generate a file that looks like:
|
|
# struct nsStaticAtom ( const char* mValue; nsIAtom** aAtom; }
|
|
# %%
|
|
# "a", &nsHTMLAtoms::a
|
|
# "body", &nsHTMLAtoms::body
|
|
#
|
|
# etc...
|
|
#
|
|
# the output can be plugged into gperf to generate a perfect hash
