mastodon-cpp/README.md

mastodon-cpp is a C++ wrapper for the Mastodon API. The library takes care of the network stuff. You submit a query and get the raw JSON. You can then put that JSON into easy to use classes.

TODO-list

Usage

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

Upgrading from below 0.7.0

Your projects will break, sorry. Here are the important changes:

• The header location has changed. They are now in mastodon-cpp/.
• Specific network error messages have been replaced by 15, "Network error". You can get the exceptions from curlpp with Mastodon::API::exceptions(true).

Most basic example

#include <iostream>
#include <string>
#include <mastodon-cpp/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';
}

Another simple example

Using the Easy-class.

#include <iostream>
#include <string>
#include <vector>
#include <mastodon-cpp/mastodon-cpp.hpp>
#include <mastodon-cpp/easy/all.hpp>

using Mastodon::Easy;

int main()
{
    Easy masto("social.example", "");
    std::string answer;
    masto.get(Mastodon::API::v1::timelines_public, answer);

    for (const std::string &str : Easy::json_array_to_vector(answer))
    {
        Easy::Status status(str);
        std::cout << "  " << status.account().acct() << " wrote:\n";
        std::cout << status.content() << '\n';
    }
}

Compiling your project

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
15	Network error (curlpp exception)
20	Failed to connect
21	Couldn't resolve host
22	Network is unreachable
23	Transfer interrupted
24	SSL error
25	Timeout
100 - 999	HTTP status codes
65535	Unknown error

If you use a debug build, you get more verbose error messages. Errors 20-25 are no longer in use (since 0.8.9).

Install

Packages

Every release includes packages for the package managers of Gentoo, Debian and Red Hat.

Gentoo

Put the ebuild into your local overlay and run ebuild <ebuild path> manifest. Install with emerge mastodon-cpp.

DEB and RPM

Prebuilt DEB and RPM packages for x86_64(amd64) are provided with each release. These packages are automatically built and not tested. Install with dpkg -i or rpm -i, respectively.

To use the DEB package on stretch, you will need libcurlpp0 from buster or jessie.

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
• -DWITHOUT_EASY=ON to not build the Easy abstractions and to get rid of the jsoncpp-dependency (not recommended)
• -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
• -DWITH_DEB=ON if you want to be able to generate a deb-package
• -DWITH_RPM=ON if you want to be able to generate an rpm-package

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

Packages

Gentoo

Put the ebuild from packages/gentoo into your local overlay and rename it to match the desired version or use the live-ebuild (mastodon-cpp-9999.ebuild) to install the development version.

DEB and RPM

Compile with -DWITH_DEB=ON or -DWITH_RPM=ON. Run make package from the build directory to generate a DEB/RPM package.

Other

Run make package from the build directory to generate a tar.gz archive.
