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](https://schlomp.space/tastytea/mastodon-cpp/milestones)

**The ABI will be unstable in versions < 1.0.0**

# Breaking API changes

I'm currently rewriting key parts of this library. The new API will be
incompatible with the old one. The new code will start with the version number
`0.100.0`. The old code is archived in the branch `pre-0.100.0` and will get
bug-fixes for a while.

**The code on the `master`-branch is not usable at the moment, stick to the
releases, please.**

# Usage

The HTML reference can be generated with `build_doc.sh`, if doxygen is
installed. It is also available at
[doc.schlomp.space/mastodon-cpp/](https://doc.schlomp.space/mastodon-cpp/annotated.html).
There are [examples](https://schlomp.space/tastytea/mastodon-cpp/src/branch/master/examples)
in `examples/`.

## Most basic example

```c++
#include <iostream>
#include <mastodon-cpp/mastodon-cpp.hpp>

int main()
{
    Mastodon::API masto("social.example.com", "auth_token");
    std::cout << masto.get(Mastodon::API::v1::accounts_verify_credentials);
    std::cout << std::endl;
}
```

## Another simple example

Using the `Easy`-class.

```c++
#include <iostream>
#include <string>
#include <mastodon-cpp/mastodon-cpp.hpp>
#include <mastodon-cpp/easy/all.hpp>

using Mastodon::Easy;

int main()
{
    Easy masto("social.example", "");
    return_call ret = masto.get(Mastodon::API::v1::timelines_public);

    for (const std::string &str : Easy::json_array_to_vector(ret.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:

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

## List of types

Learn more at <https://doc.schlomp.space/mastodon-cpp/namespaceMastodon.html>

### Return types

* `Mastodon::return_call`: Contains the response from `Mastodon::API` calls.
* `Mastodon::Easy::return_entity`: Contains the response from
  `Mastodon::Easy::API` calls that return a single `Mastodon::Easy::Entity`.

  `Mastodon::Easy::API` calls that return multiple `Mastodon::Easy::Entity`.

### Other types

* `Mastodon::param`: A single parameter to an `Mastodon::API` call. Normally you
  don't need this.
* `Mastodon::parameters`: All parameters to an `Mastodon::API` call.
* `Mastodon::http_method`: HTTP method of an `Mastodon::API` call.

* `Mastodon::Easy::stream_event`: Type and data of an events returned in
  streams.
* `Mastodon::Easy::alert_type`: Type for a single alert.
* `Mastodon::Easy::alerts`: Vector of `Mastodon::Easy::alert_type`, used for
  push subscriptions.
* `Mastodon::Easy::time`: Type for time, can be converted to `time_point` and
  `string`.

|       255 | Unknown error                              |

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

# Install

## Packages

Every [release](https://schlomp.space/tastytea/mastodon-cpp/releases) includes
packages for the package managers of Debian and Red Hat. Gentoo packages are
available in an overlay.

### Gentoo

Add my [repository](https://schlomp.space/tastytea/overlay) and
install it from there.

```shellsession
eselect repository enable tastytea
echo 'dev-cpp/mastodon-cpp ~amd64' >> /etc/portage/package.keywords/mastodon-cpp
emaint sync -r tastytea
emerge -a dev-cpp/mastodon-cpp
```

### DEB and RPM

Prebuilt DEB and RPM packages for x86_64(amd64) are provided with each release.
`.deb` packages are built on Debian stretch and `.rpm` packages are built on
CentOS 7. These packages are automatically built and not tested. Install with
`dpkg -i` or `rpm -i`, respectively.

To use the DEB package on Debian stretch, you will need
[libcurlpp0](https://packages.debian.org/libcurlpp0) from sid.
