After you have forked groue/GRMustache, you might want to change stuff, test, and then build the library.
You'll find below some useful information on each of those topics.
Objective-C files that make GRMustache are stored in the src/classes
folder. They are added to both GRMustache4-MacOS
and GRMustache4-iOS
targets of the src/GRMustache.xcodeproj
project.
Headers are splitted in two categories:
- public headers
- private headers
Public headers must contain only declarations for APIs that are exposed to the GRMustache users. They must not import or include any private header.
Methods and functions declared in public headers must be decorated with the macros defined in Classes/GRMustacheAvailabilityMacros.h
. Check existing public headers for inspiration.
src/classes/GRMustacheAvailabilityMacros.h
is generated by src/bin/buildGRMustacheAvailabilityMacros
.
Private headers have names ending in _private.h
. They must not import or include any public header. The set of public APIs must be duplicated in both public and private headers.
Before running the tests, make sure git submodules are downloaded:
$ git submodule update --init
There are two kinds of tests, all stored in the src/tests
folder.
- tests of private APIs
- tests of public APIs
When a file is added or removed from the src/tests
folder, both GRMustache4-MacOSTests
and GRMustache4-iOSTests
targets of the src/GRMustache.xcodeproj
project are updated.
Tests of private internals are stored in the src/tests/Private
folder, and are all subclasses of GRMustachePrivateAPITest
.
The implementation files of those tests must not include any public header.
Tests of public GRMustache API are versionned: the src/tests/Public/v4.0
folder contains tests for features introduced in the version 4.0 of the library. src/tests/Public/v4.1
contains tests for the version 4.1, etc.
Those tests are all subclasses of GRMustachePublicAPITest
. Their implementation files must not include any private header.
You will use the macros defined in Classes/GRMustacheAvailabilityMacros.h
. They help the tests acheiving three goals:
- use only APIs that are available in the GRMustache version they test against,
- emit deprecation warning when they use deprecated GRMustache APIs,
- help GRMustache achieve full backward compatibility.
For instance, all header files for public API tests in src/tests/Public/v4.1
would begin with:
#define GRMUSTACHE_VERSION_MAX_ALLOWED GRMUSTACHE_VERSION_4_1
#import "GRMustachePublicAPITest.h"
When you add a test for a public API, make sure you place it in the folder that introduced the API (check the release notes), and NOT in the version that will include the new code. For instance, if version 4.6 introduces a fix for an API that was introduced in version 4.2, the version 4.6 will then ship with new tests in the src/tests/Public/v4.2 folder.
Building GRMustache is building the /lib
and /include
folders, which contain public headers and static libraries for iOS and MacOS.
In order to build them: make sure git submodules are downloaded first:
$ git submodule update --init
Then, issue the following command:
$ make clean && make
