1	1
2	2	CrossGuid is a minimal, cross platform, C++ GUID library. It uses the best
3		native GUID/UUID generator on the given platform and had a generic class for
4		parsing, stringifying, and comparing IDs. The intention is that anyone who
5		uses this code can simply copy `guid.h` and `guid.cpp` into their project and
6		define one of the following preprocessor flags to control the implementation:
7
8		* `GUID_LIBUUID` - Uses `libuuid` which is normally used on linux but possibly
9		usable elsewhere as well.
10		* `GUID_CFUUID` - Uses `CFCreateUUID` from Apple's `CoreFoundation` framework.
11		This works on both Mac OSX and iOS.
12		* `GUID_WINDOWS` - Uses the built in `CoCreateGuid` function in Windows.
13		* `GUID_ANDROID` - Uses JNI to invoke Java functions from Android SDK.
14
15		I recommend taking the time to actually look at the `guid.h` and `guid.cpp` so
16		that you can see how simple they are. It should be pretty trivial to modify
17		the code to match your naming conventions or drop it into a namespace so that it
18		fits in nicely with your code base.
	3	native GUID/UUID generator on the given platform and has a generic class for
	4	parsing, stringifying, and comparing IDs. The guid generation technique is
	5	determined by your platform:
	6
	7	## Linux
	8
	9	On linux you can use `libuuid` which is pretty standard. On distros like Ubuntu
	10	it is available by default but to use it you need the header files so you have
	11	to do:
	12
	13	sudo apt-get install uuid-dev
	14
	15	## Mac/iOS
	16
	17	On Mac or iOS you can use `CFUUIDCreate` from `CoreFoundation`. Since it's a
	18	plain C function you don't even need to compile as Objective-C++.
	19
	20	## Windows
	21
	22	On Windows we just use the the built-in function `CoCreateGuid`. CMake can
	23	generate a Visual Studio project if that's your thing.
	24
	25	## Android
	26
	27	The Android version uses a handle to a `JNIEnv` object to invoke the
	28	`randomUUID()` function on `java.util.UUID` from C++. The Android specific code
	29	is all in the `android/` subdirectory. If you have an emulator already running,
	30	then you can run the `android.sh` script in the root directory. It has the
	31	following requirements:
	32
	33	- Android emulator is already running (or you have physical device connected).
	34	- You're using bash.
	35	- adb is in your path.
	36	- You have an Android sdk setup including `ANDROID_HOME` environment variable.
	37
	38	## Versions
	39
	40	This is version 0.2 of CrossGuid. If you all already using CrossGuid and your code
	41	uses `GuidGenerator` then you are using version 0.1. Differences in version 0.2:
	42
	43	- Put everything inside the namespace `xg` instead of using the global
	44	namespace.
	45	- Removed `GuidGenerator` class and replaced with the free function
	46	`xg::newGuid`. This is the way I originally wanted it to work but since Android
	47	is a special snowflake requiring state (`JNIEnv *`) I introduced the
	48	`GuidGenerator` class specifically so that there would be somewhere to store
	49	the `JNIEnv *` when running on Android. However, this basically meant
	50	complicating the library for the sake of one platform. In version 0.2 the goal is
	51	to design for the normal platforms and let Android be weird. In Android you just
	52	need to run `xg::initJni(JNIEnv )` before you create any guids. The `JNIEnv `
	53	is just stored as a global variable.
	54	- Added CMake build system. Instead of different scripts for each platform you
	55	can just run cmake and it should handle each platform (except Android which
	56	again is special).
	57	- Actual guid bytes are stored in `std::array<unsigned char, 16>` instead of
	58	`std::vector<unsigned char>`.
	59	- More error checking (like if you try to create a guid with invalid number of
	60	bytes).
	61
	62	If you're happily using version 0.1 then there's not really any reason to
	63	change.
	64
	65	## Compiling
	66
	67	Just do the normal cmake thing:
	68
	69	```
	70	mkdir build
	71	cd build
	72	cmake ..
	73	make install
	74	```
	75
	76	## Running tests
	77
	78	After compiling as described above you should get two files: `libcrossguid.a` (the
	79	static library) and `crossguid-test` (the test runner). So to run the tests just do:
	80
	81	```
	82	./crossguid-test
	83	```
19	84
20	85	## Basic usage
21	86
22		### Tests
23
24		The tests are a simple way to figure out how the library works. There is a file
25		in the root of the repository called `test.cpp` that runs a simple set of tests
26		and outputs a few guid strings for a sanity check. This file does not have a
27		`main()` function entry point there, it is intended to be called from somewhere
28		else, and it takes a `GuidGenerator` as input. All platforms except for Android
29		use `testmain.cpp` to construct a `GuidGenerator` and run the tests. In Android
30		there is a special file called `android/jni/jnitest.cpp` which invokes the
31		tests.
32
33		### Creating a guid generator
34
35		Creation of a guid generator is not exactly the same in every platform, but
36		this is an intentional feature. In Android the guid generation function has to
37		have access to a `JNIEnv` handle, but that handle is not necessarily the same
38		all the time. Therefore, there is a `GuidGenerator` class whose construction is
39		different depending on the platform, but client code can pass around a
40		`GuidGenerator` object and then use it the same on every platform. On every
41		platform except Android, you can create a guid generator like this:
42
43		GuidGenerator generator;
44
45		But on Android you need to pass a `JNIEnv *`:
46
47		GuidGenerator generator(env);
48
49	87	### Creating guids
50	88
51		On every platform guid creation is the same:
52
53		void doGuidStuff(GuidGenerator generator)
54		{
55		auto myGuid = generator.newGuid();
56		}
	89	Create a new random guid:
	90
	91	```cpp
	92	#include <crossguid/guid.hpp>
	93	...
	94	auto g = xg::newGuid();
	95	```
	96
	97	NOTE: On Android you need to call `xg::initJni(JNIEnv *)` first so that it
	98	is possible for `xg::newGuid()` to call back into java libraries. `initJni`
	99	only needs to be called once when the process starts.
	100
	101	Create a new zero guid:
	102
	103	```cpp
	104	xg::Guid g;
	105	```
	106
	107	Create from a string:
	108
	109	```cpp
	110	xg::Guid g("c405c66c-ccbb-4ffd-9b62-c286c0fd7a3b");
	111	```
	112
	113	### Checking validity
	114
	115	If you have some string value and you need to check whether it is a valid guid
	116	then you can simply attempt to construct the guid:
	117
	118	```cpp
	119	xg::Guid g("bad-guid-string");
	120	if (!g.isValid())
	121	{
	122	// do stuff
	123	}
	124	```
	125
	126	If the guid string is not valid then all bytes are set to zero and `isValid()`
	127	returns `false`.
57	128
58	129	### Converting guid to string
59	130

64	135	utilize strings because the `<<` operator is overloaded. To print a guid to
65	136	`std::cout`:
66	137
67
68		void doGuidStuff(GuidGenerator generator)
69		{
70		auto myGuid = generator.newGuid();
71		std::cout << "Here is a guid: " << myGuid << std::endl;
72		}
	138	```cpp
	139	void doGuidStuff()
	140	{
	141	auto myGuid = xg::newGuid();
	142	std::cout << "Here is a guid: " << myGuid << std::endl;
	143	}
	144	```
73	145
74	146	Or to store a guid in a `std::string`:
75	147
76		void doGuidStuff(GuidGenerator generator)
77		{
78		auto myGuid = generator.newGuid();
79		std::stringstring stream;
80		stream << myGuid;
81		auto guidString = stream.str();
82		}
83
84		### Parsing a string into a guid
85
86		There is a constructor that can be used to create a guid from a string without
87		needing any reference to a `GuidGenerator`:
88
89		void doGuidStuff()
90		{
91		Guid guid("e63e03a8-f3e5-4e0f-99bb-a3fc402d4fc8");
92		}
	148	```cpp
	149	void doGuidStuff()
	150	{
	151	auto myGuid = xg::newGuid();
	152	std::stringstream stream;
	153	stream << myGuid;
	154	auto guidString = stream.str();
	155	}
	156	```
	157
	158	There is also a `str()` function that returns a `std::string`:
	159
	160	```cpp
	161	std::string guidStr = xg::newGuid().str();
	162	```
93	163
94	164	### Creating a guid from raw bytes
95	165

97	167	internally to construct a `Guid` object from the raw data given by the system's
98	168	built-in guid generation function. There are two key constructors for this:
99	169
100		Guid(const vector<unsigned char> &bytes);
	170	```cpp
	171	Guid(std::array<unsigned char, 16> &bytes);
	172	```
101	173
102	174	and
103	175
104		Guid(const unsigned char *bytes);
105
106		In both cases the constructor expects to receive exactly 16 bytes.
	176	```cpp
	177	Guid(const unsigned char * bytes);
	178	```
	179
	180	When possible prefer the `std::array` constructor because it is safer. If you
	181	pass in an incorrectly sized C array then bad things will happen.
107	182
108	183	### Comparing guids
109	184
110	185	`==` and `!=` are implemented, so the following works as expected:
111	186
112		void doGuidStuff(GuidGenerator generator)
113		{
114		auto guid1 = generator.newGuid();
115		auto guid2 = generator.newGuid();
116
117		auto guidsAreEqual = guid1 == guid2;
118		auto guidsAreNotEqual = guid1 != guid2;
119		}
120
121		## Linux
122
123		The Linux version uses the proprocessor flag `GUID_LIBUUID`
124
125		On linux you can use libuuid which is pretty standard. On distros like Ubuntu
126		it is available by default but to use it you need the header files so you have
127		to do:
128
129		sudo apt-get install uuid-dev
130
131		Then you can compile and run tests with:
132
133		./linux.sh
134
135		## Mac/iOS
136
137		The Mac and iOS versions use the preprocessor flag `GUID_CFUUID`
138
139		On Mac or iOS you can use `CFUUIDCreate` from `CoreFoundation`. Since it's a
140		plain C function you don't even need to compile as Objective-C++. If you have
141		the command line tools that come with Xcode installed, then you can compile and
142		run the tests like this:
143
144		./mac.sh
145
146		## Windows
147
148		The Windows version uses the preprocessor flag `GUID_WINDOWS`
149
150		On Windows we just the the built-in function `CoCreateGuid`. There is a Visual
151		Studio 2013 solution in the `VisualStudio` directory which you can use to
152		compile and run tests.
153
154		## Android
155
156		The Android version uses the preprocessor flag `GUID_ANDROID`
157
158		The Android version uses a handle to a `JNIEnv` object to invoke the
159		`randomUUID()` function on `java.util.UUID` from C++. The Android specific code
160		is all in the `android/` subdirectory. If you have an emulator already running,
161		then you can run the `android.sh` script in the root directory. It has the
162		following requirements:
163
164		* Android emulator is already running (or you have physical device connected).
165		* You're using bash.
166		* adb is in your path.
167		* ndk-build and other ndk cross-compile tools are in your path.
168		* You have a jdk setup including `JAVA_HOME` environment variable.
	187	```cpp
	188	void doGuidStuff()
	189	{
	190	auto guid1 = xg::newGuid();
	191	auto guid2 = xg::newGuid();
	192
	193	auto guidsAreEqual = guid1 == guid2;
	194	auto guidsAreNotEqual = guid1 != guid2;
	195	}
	196	```
	197
	198	### Hashing guids
	199
	200	Guids can be used directly in containers requireing `std::hash` such as `std::map,`std::unordered_map` etc.
