2021-03-07Makefile: Add rules to build a distribution tarballv0.0.1Teddy Wing
2021-03-07Add license (GNU GPLv3+)Teddy Wing
2021-03-07Makefile: Add a `clean` targetTeddy Wing
Give us a way to remove all build files.
2021-03-07Makefile: Annotate `all` target as phonyTeddy Wing
2021-03-07Makefile: Finalise the executable nameTeddy Wing
2021-03-07Makefile: Create build directoriesTeddy Wing
Ensure the build directories are available when building. Read up on techniques for creating directories in prerequisites here: https://www.cmcrossroads.com/article/making-directories-gnu-make
2021-03-07Makefile: Fix link error for `UCKeyTranslate`Teddy Wing
The linker complained about `_UCKeyTranslate` being undefined. It's used by DDHotKey, and is defined in `CoreServices.framework`, so we need to link CoreServices. Here's the error I was getting: clang -x objective-c \ -mmacosx-version-min=10.7 \ -framework Carbon \ -framework Cocoa \ -framework CoreGraphics \ -framework Foundation \ -fno-objc-arc \ -I./build/include \ -L./build \ -lddhotkey \ -o invert-catalina-invert \ Invert.h Invert.m main.m Undefined symbols for architecture x86_64: "_UCKeyTranslate", referenced from: _DDStringFromKeyCode in libddhotkey.a(DDHotKeyUtilities.o) ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
2021-03-07Makefile: Set minimum Mac OS X version to 10.7Teddy Wing
Build for as early a Mac OS X version as we can. Can't build for 10.5 because only 10.6+ supports ARC. Can't build for 10.6 because DDHotKey requires weak references, and these are only supported starting in 10.7: https://en.wikipedia.org/w/index.php?title=Weak_reference&oldid=1000364515#Objective-C_2.0
2021-03-07Makefile: Don't copy DDHotKey headers multiple timesTeddy Wing
Previously, the rule was copying all header files for every header file: cp lib/DDHotKey/Compatibility.h lib/DDHotKey/DDHotKeyAppDelegate.h lib/DDHotKey/DDHotKeyCenter.h lib/DDHotKey/DDHotKeyTextField.h lib/DDHotKey/DDHotKeyUtilities.h build/include/ cp lib/DDHotKey/Compatibility.h lib/DDHotKey/DDHotKeyAppDelegate.h lib/DDHotKey/DDHotKeyCenter.h lib/DDHotKey/DDHotKeyTextField.h lib/DDHotKey/DDHotKeyUtilities.h build/include/ cp lib/DDHotKey/Compatibility.h lib/DDHotKey/DDHotKeyAppDelegate.h lib/DDHotKey/DDHotKeyCenter.h lib/DDHotKey/DDHotKeyTextField.h lib/DDHotKey/DDHotKeyUtilities.h build/include/ cp lib/DDHotKey/Compatibility.h lib/DDHotKey/DDHotKeyAppDelegate.h lib/DDHotKey/DDHotKeyCenter.h lib/DDHotKey/DDHotKeyTextField.h lib/DDHotKey/DDHotKeyUtilities.h build/include/ cp lib/DDHotKey/Compatibility.h lib/DDHotKey/DDHotKeyAppDelegate.h lib/DDHotKey/DDHotKeyCenter.h lib/DDHotKey/DDHotKeyTextField.h lib/DDHotKey/DDHotKeyUtilities.h build/include/ Change it to only copy once per header: cp lib/DDHotKey/Compatibility.h build/include/ cp lib/DDHotKey/DDHotKeyAppDelegate.h build/include/ cp lib/DDHotKey/DDHotKeyCenter.h build/include/ cp lib/DDHotKey/DDHotKeyTextField.h build/include/ cp lib/DDHotKey/DDHotKeyUtilities.h build/include/
2021-03-07Makefile: Stop suppressing warnings when compiling `DDHotKey`Teddy Wing
Fixed the warnings in a fork.
2021-03-07Makefile: Remove `-framework` arguments when building DDHotKey obj filesTeddy Wing
I was getting warnings that these arguments are unused because we're not linking anything in this command: $ clang -x objective-c \ -framework Carbon \ -framework Cocoa \ -framework Foundation \ -fobjc-arc \ -c \ lib/DDHotKey/DDHotKeyCenter.m clang: warning: -framework Carbon: 'linker' input unused [-Wunused-command-line-argument] clang: warning: -framework Cocoa: 'linker' input unused [-Wunused-command-line-argument] clang: warning: -framework Foundation: 'linker' input unused [-Wunused-command-line-argument]
2021-03-07Makefile: Compile DDHotKey object files individuallyTeddy Wing
Need to input each file individually to get object files for each one.
2021-03-07Makefile: Remove unused codeTeddy Wing
These lines are old and unused.
2021-03-07Register a global hotkeyTeddy Wing
Build DDHotKey as a static library so we can compile it with ARC turned on and our project with ARC turned off. Since DDHotKey is written with ARC, if I include its headers directly, I'd need to enable ARC on my project in order to compile it. Initialise an `NSApplication` to give us an environment in which to register the global hotkey. A new class `Invert` will respond to the hotkey and respond accordingly.
2021-03-05Makefile: Fix `CoreGraphics` framework capitalisationTeddy Wing
2021-03-03Try inverting display coloursTeddy Wing
Invert the screen colours for as long as the program is active. Only works on the main display currently. Inspired by Nikolai Ruhe's (https://stackoverflow.com/users/104790/nikolai-ruhe) answer on Stack Overflow about screen colour inversion: https://stackoverflow.com/questions/14163788/how-does-on-screen-color-inversion-work-in-os-x/14165523#14165523 and this question: https://stackoverflow.com/questions/32823023/permanently-modifying-rgb-gamma-table
