# Case conversion macros. This is inspired by the 'up' macro from gmsl
|
|
# (http://gmsl.sf.net). It is optimised very heavily because these macros
|
|
# are used a lot. It is about 5 times faster than forking a shell and tr.
|
|
#
|
|
# The caseconvert-helper creates a definition of the case conversion macro.
|
|
# After expansion by the outer $(eval ), the UPPERCASE macro is defined as:
|
|
# $(strip $(eval __tmp := $(1)) $(eval __tmp := $(subst a,A,$(__tmp))) ... )
|
|
# In other words, every letter is substituted one by one.
|
|
#
|
|
# The caseconvert-helper allows us to create this definition out of the
|
|
# [FROM] and [TO] lists, so we don't need to write down every substition
|
|
# manually. The uses of $ and $$ quoting are chosen in order to do as
|
|
# much expansion as possible up-front.
|
|
#
|
|
# Note that it would be possible to conceive a slightly more optimal
|
|
# implementation that avoids the use of __tmp, but that would be even
|
|
# more unreadable and is not worth the effort.
