### RB: Follow Another User

How to follow/unfollow another user.

Full, runnable src of Follow Another User can be downloaded as part of the RB tutorials repository.

This tutorial will take you through the process of following/muting/unfollowing/ummuting an author and checking the follow status of an author.

### Sections

1. Follow
2. Check Follow
3. To Run - Running the example.

### Follow

In the first example script, we can modify the initial configuration then run:

    ruby follow.rb

Follows (and mutes) are expressed by `custom_json` with `id=follow` (mutes also use `id=follow`).

Example `custom_json` operation:

    {
      "id": "follow",
      "required_auths": [],
      "required_posting_auths": ["social"],
      "json": "[\"follow\",{\"follower\":\"social\",\"following\":\"alice\",\"what\":[\"blog\"]}]"
    }

To broadcast this operation, use the posting `wif` and matching account name in `required_posting_auths`. There are three variables required in the `json` field of the above operation:

1. `follower` - The specific account that will select the author to follow/unfollow.
2. `following` - The account/author that the account would like to follow.
3. `what` - The type of follow operation. This variable can have one of three values: `blog` to follow an author, `ignore` to mute, and an empty string to unfollow/unmute.

#### Check Follow

In the second example script:

    ruby check_follow.rb

The API method we’re using here is `condenser.get_following`. We pass the name of the account we’re checking. If the account follows more than 1,000 other accounts, we execute `condenser.get_following` multiple times and pass the last followed account we know about to get the next 1,000 (passing the latest `follows.last` each time).

We also specify `blog` to tell the API method that we’re looking for followed, not muted (to locate muted accounts, use `ignore` instead of `blog`).

### To Run

First, set up your workstation using the steps provided in Getting Started. Then you can create and execute the script (or clone from this repository):

    git clone git@github.com:steemit/devportal-tutorials-rb.git
    cd devportal-tutorials-rb/tutorials/18_follow_another_user
    bundle install
    ruby follow.rb
