# libmaple's own Evil Mangler
#
# Input filter hack to trick Doxygen into thinking that a series
# header is in a separate namespace. This is necessary because Doxygen
# doesn't know how to cope with two data structures with the same name
# in different places in the project. (We do that all the time,
# e.g. for foo_reg_map structs.)
#
# E.g., an STM32F1 header gets transformed into:
#
# namespace stm32f1 {
# <contents of header>
# }
BEGIN {
# For extracting series component from header FILENAME.
series_regex = "/stm32[flw][0-9]*-?[flw]?[0-9]*/";
# Holds header FILENAME. Cargo-culted; not sure why it's necessary.
f = "";
# Holds series component.
series = "";
}
{
if (f != FILENAME) {
f = FILENAME;
match(f, series_regex);
series = substr(f, RSTART + 1, RLENGTH - 2);
sub(/-/, "_", series);
printf("namespace %s {\n", series);
}
print;
}
END {
if (series != "") {
print "}"
}
