**mastodon-cpp** is a C++ wrapper for the Mastodon API. You submit an API call
and get the raw JSON or easy to use abstractions.

# Usage
2019-04-02 11:28:53 +02:00
The HTML reference can be generated with `build_doc.sh`, if doxygen is
2019-04-13 21:50:20 +02:00
installed. It is also available at
[doc.schlomp.space/mastodon-cpp/](https://doc.schlomp.space/mastodon-cpp/annotated.html).
2019-04-02 11:28:53 +02:00
There are [examples](https://schlomp.space/tastytea/mastodon-cpp/src/branch/master/examples)
in `examples/`.
2018-03-18 01:43:09 +01:00
## Most basic example
2019-04-02 11:28:53 +02:00
```c++
2018-03-18 01:43:09 +01:00
#include <iostream>
#include <mastodon-cpp/mastodon-cpp.hpp>
2018-03-18 01:43:09 +01:00
int main()
{
Mastodon::API masto("social.example.com", "auth_token");
2019-03-03 11:22:11 +01:00
std::cout << masto.get(Mastodon::API::v1::accounts_verify_credentials);
std::cout << std::endl;
2018-03-18 01:43:09 +01:00
}
```
2018-04-01 05:03:35 +02:00
## Another simple example
2019-04-14 06:21:26 +02:00
Using the `Easy` interface.
2018-04-01 05:03:35 +02:00
2019-04-02 11:28:53 +02:00
```c++
2018-04-01 05:03:35 +02:00
#include <iostream>
#include <string>
#include <mastodon-cpp/mastodon-cpp.hpp>
#include <mastodon-cpp/easy/all.hpp>
2019-04-14 06:21:26 +02:00
using Mastodon;
2018-04-01 05:03:35 +02:00
int main()
{
2019-04-14 06:21:26 +02:00
Easy::API masto("social.example", "");
return_call ret = masto.get(API::v1::timelines_public);
2018-04-01 05:03:35 +02:00
2019-03-03 11:22:11 +01:00
for (const std::string &str : Easy::json_array_to_vector(ret.answer))
2018-04-01 05:03:35 +02:00
{
Easy::Status status(str);
std::cout << " " << status.account().acct() << " wrote:\n";
std::cout << status.content() << '\n';
}
}
```

# Install
2019-04-14 06:21:26 +02:00
## Upgrading from versions below 0.100.0
Starting with version `0.100.0`, large parts of the library have been rewritten.
Upgrading from previous versions will require extensive code changes. You can
keep using the old version, it is archived in the branch
[pre-0.100.0](https://schlomp.space/tastytea/mastodon-cpp/src/branch/pre-0.100.0).
It will receive bug-fixes for a while but no new features.
2018-03-18 01:32:54 +01:00
