Raw Blame History

**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.
**The ABI will be unstable in versions < 1.0.0**
[Subscribe to mastodon-cpp releases](https://rss.schlomp.space/?repo=tastytea/mastodon-cpp).
# 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` interface.
```c++
#include <iostream>
#include <string>
#include <mastodon-cpp/mastodon-cpp.hpp>
#include <mastodon-cpp/easy/all.hpp>
using Mastodon;
int main()
{
Easy::API masto("social.example", "");
return_call ret = masto.get(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
```

# Install
## 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.
## Packages
Every [release](https://schlomp.space/tastytea/mastodon-cpp/releases) includes
packages for Debian and Centos. Gentoo packages are available in my 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.accept_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.
To use the `.deb` package on Debian stretch, you will need
[libcurlpp0](https://packages.debian.org/libcurlpp0) from sid.
To use the `.rpm` package on CentOS 7, you will need
[libcurlpp](https://download.fedoraproject.org/pub/epel/6/x86_64/Packages/c/)
from EPEL 6.

### Get sourcecode
#### Release
Download the current release at
[schlomp.space](https://schlomp.space/tastytea/mastodon-cpp/releases).
#### Development version
```shellsession
git clone https://schlomp.space/tastytea/mastodon-cpp.git
```
### Compile
```shellsession
mkdir build
cd build/
cmake ..
cmake --build . -- -j$(nproc --ignore=1)
```
cmake options:
* `-DCMAKE_BUILD_TYPE=Debug` for a debug build
* `-DWITH_EASY=NO` to not build the Easy abstractions and to get rid of the
jsoncpp-dependency (not recommended)
* `-DWITH_EXAMPLES=YES` if you want to compile the examples
* `-DWITH_TESTS=YES` if you want to compile the tests
* `-DEXTRA_TEST_ARGS` to run only some tests
* Possible values: `[api]`, `[mastodon]`, `[glitch-soc]`, `[pleroma]`
* Example: `-DEXTRA_TEST_ARGS=[pleroma]![mastodon]` to run the tests for features
in Pleroma that are not in Mastodon.
* `-DWITH_DOC=NO` if you don't want to compile the HTML reference
* One of:
* `-DWITH_DEB=YES` if you want to be able to generate a deb-package
* `-DWITH_RPM=YES` if you want to be able to generate an rpm-package
Install with `make install`.
### Tests
You can run the tests with `ctest` inside the build directory. You need to set
the environment variable `MASTODON_CPP_ACCESS_TOKEN` to an access token with the
scopes *read*, *write* and *follow* for some tests.
You can select the instance to use with `MASTODON_CPP_INSTANCE`, the default is
*likeable.space*. You can select the user ID with `MASTODON_CPP_USER_ID`, the
default is *9hnrrVPriLiLVAhfVo*. You can select the status ID with
`MASTODON_CPP_STATUS_ID`, the default is *9hwnuJMq3eTdO4s1PU*. You can select
the filter ID with `MASTODON_CPP_FILTER_ID`.
Requirements for the test-user:
* Have at least 1 follower.
* Follow at least 1 account.
* Have at least 1 account endorsed.
* Have at least 1 public or unlisted status.
* Have at least 1 post favourited.
* Have no follow requests.
* Have at least 1 list with at least one account in it.
### Packages
#### 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.
