OFINICategory is provided as a deprecated subclass of OFINISection to
maintain API and ABI compatibility. file: [56fd049fb8] check-in: [0fead8a915] user: js, branch: trunk, size: 4857 [annotate] [blame] [check-ins using] [diff]

This allows ABI stability with the fragile ABI. file: [71d6c12d86] check-in: [496695d778] user: js, branch: trunk, size: 3345 [annotate] [blame] [check-ins using] [diff]

Instead, explicitly declare them, as OF_ASSUME_NONNULL_{BEGIN,END} does
not apply to implicit return types. This means that after this commit,
all init methods have a nonnull return type, as they should have. file: [40d24517e7] check-in: [2f4e0df8be] user: js, branch: trunk, size: 3290 [annotate] [blame] [check-ins using] [diff]

Casts are now written like types in variable declarations. file: [233379f0e4] check-in: [4af49a13c3] user: js, branch: trunk, size: 3194 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [1a37c007aa] check-in: [44f45c2e35] user: js, branch: trunk, size: 3185 [annotate] [blame] [check-ins using] [diff]

While at it, also update the mail address. file: [140ee5468f] check-in: [2a27cf3000] user: js, branch: trunk, size: 3179 [annotate] [blame] [check-ins using] [diff]

This is a much more logical way to handle leading and trailing
whitespaces and also seems to be used by a few other INI
implementations.

Additionally, this imports OFINICategory.h in OFINIFile.h so that
importing OFINIFile.h is enough - this should be less confusing - and
allows opening non-existant files, treating them like an empty file. file: [d3236d0058] check-in: [12c5b7ee91] user: js, branch: trunk, size: 1936 [annotate] [blame] [check-ins using] [diff]
