mastodon-cpp is a C++ wrapper for the Mastodon API. The aim is to be as simple as possible. The library takes care of the network stuff. You submit a query and get the raw JSON. All versions below 1.0.0 (SOVERSION 0) are considered unstable and can change any time.

Release

Download the current release at GitHub.

Development version

git clone https://github.com/tastytea/mastodon-cpp.git

Compile

mkdir build
cd build/
cmake ..
make

cmake options:

• -DCMAKE_BUILD_TYPE=Debug for a debug build
• -DWITH_EXAMPLES=ON if you want to compile the examples
• -DWITH_TESTS=ON if you want to compile the tests
• -DWITH_DOC=ON if you want to compile the HTML reference

You can run the tests with ctest .. inside the build directory. Install with make install.

Usage

The HTML reference can be generated with build_doc.sh, if doxygen is installed. Or just look in src/mastodon-cpp.hpp. It is also available at tastytea.github.io/mastodon-cpp/. There are examples in src/examples/.

Most basic example

#include <iostream>
#include <string>
#include <mastodon-cpp.hpp>

int main()
{
    Mastodon::API masto("social.example.com", "auth_token");
    std::string answer;
    masto.get(Mastodon::API::v1::accounts_verify_credentials, answer);
    std::cout << answer << '\n';
}

Compiling your project

After you did a make install, a project consisting of one file can be compiled as follows:

g++ -std=c++14 -lmastodon-cpp example.cpp

Error codes

mastodon-cpp will never use error codes below 11, except 0.

Code	Explanation
0	No error
11	Invalid call
12	Not implemented
13	URL changed (HTTP 301 or 308)
14	Aborted by user
20	Failed to connect
21	Couldn't resolve host
22	Network is unreachable
100 - 999	HTTP status codes
65535	Unknown error

If you use a debug build, you get more verbose error messages.
