About

dontwi is a status transporter script from Mastodon instances to Twitter. It transports statuses triggered by your preferred hashtag in Mastodon public timeline to a twitter account with #don_tw hashtag. Its aim is communication with Mastodon users and the Twitter's follers. This idea was described on Mastodon 2 Advent Calendar 2017 by TOMOKI++(@tomoki@vocalodon.net).

Features

  • dontwi supports Python 3.4 and higher on CentOS 7.4, Ubuntu 16.04 and Windows 10.
  • Efficiently to use with cron. It transports only one status each run.
  • Statues with the specified tag in Mastodon public local timeline are transferred.
  • Long text in Mastodon status is truncated to fit for Twitter.
  • Username at Mastodon is attached to Twitter status.
  • The attached image is also transported with status text.
  • Statuses recorded as sent has never been sent again.

How it works

dontwi transports statuses with a specific hashtag on Mastodon's local timeline. For example, Fig.1 status on Mastodon is brought to Twitter like Fig.2.

Fig.1 Sample status on Mastodon

images/result_tweet.png

Fig.2 Transported status on Twitter

dontwi gets hashtag timeline each run using Mastodon API. When it finds statuses with a specified hashtag and #don_tw, it stores these statues in the log DB.

Next, it takes the oldest status from the log DB, posts the status to Twitter by API. It appends the contributor's address on Mastodon and #don_tw hashtag to the status. Also, it brings attached media files [1] which is shrunk for Twitter if the resolution exceeds Twitter's specifications.

All of the contents that are text, link address, and hashtag are kept if the number of characters is within 280, which is the limit of Twitter. When the length exceeds the limit, dontwi trims text without modification link and hashtag as much as possible. dontwi can also split status text and post as a thread(v1.1.0 or later).

#don_tw hashtag appended to the post to Twitter is not configurable. The reason why is aiming to organize federation timeline like Mastodon's one on Twitter by this fixed hashtag. If you want to use another hashtag, you can do by modification to source code directory. However, we hope you keep this hashtag for the federation timeline on Twitter.

[1]This is currently only available for image files.

Installation

You can easily install dontwi package from this repository using pip3 via:

pip3 install https://github.com/vocalodon/dontwi/releases/download/v1.1.1/dontwi-1.1.1-py3-none-any.whl

You can also use setup.py to install from your local repository via:

python3 setup.py install

Setting up

1. Place the configuration file

You should place the configuration file dontwi.ini to /etc. Search paths of dontwi.ini are /etc and current directory. You can use examples/dontwi.ini as a template via:

[operation]
inbound = your_mastodon
trigger = hashtag:your_hashtag
outbound = dontwi

[endpoint your_mastodon]
type = mastodon
api_base_url = https://your_mastodon.domain
client_name = dontwi
since =

[endpoint dontwi]
type = twitter
app_key =
app_secret =
oauth_token =
oauth_token_secret =
message_length = 280
post_mode = single

[result log]
db_file = /var/db/dontwi_log.db

2. Modify configuration for your instance

You should modify dontwi.ini for your Mastodon instance and Twitter account. Required minimum modification parameters are below. It is better not to write comments because of dontwi deletes these when saving Mastodon's client keys.

operation section

inbound

Section name of the inbound endpoint parameters

You can change this name. However, keep the name consistent with the section name of endpoint definition.

trigger

Hashtag to detect status you want to transfer

Set the hashtag with prefix hashtag: and without # mark.

outbound

Section name of the outbound endpoint parameters

See above note for inbound setting.

endpoint your_mastodon section

type

Type name of the endpoint

Set mastodon. In the future, we may implement another type support.

api_base_url
Set base URL of your Mastodon instance.
client_name
Client name at API access

endpoint dontwi section

type

Type name of the endpoint

Set twitter. In the future, we may implement another type support.

app_key, app_secret, oauth_token, oauth_token_secret
Set Twitter API key and related parameters. dontwi uses Twython library to access to Twitter. Please refer Twython's documents to obtain these keys.
message_length
Max character length at trimming message text. The default is 280.
post_mode
single``(default) or ``thread can be selected. In single case, dontwi posts trimmed status text within message_length characters. In thread case, it splits status text by message_length characters and post as a thread.

result log section

db_file

Log DB file path

Set log DB file path. Default is dontwi_log.db on current directory. We recommend using /var/db/dontwi_log.db according to FHS.

3. Check your configuration

You can confirm dontwi installation by a test run with --help option via:

[root@centos7 opt]# dontwi --help
usage: dontwi [-h] [--config-file CONFIG_FILE] [--summary] [--trigger TRIGGER]
          [--since SINCE] [--until UNTIL] [--limit LIMIT] [--dry-run]
          [--get-secret] [--dump-status-strings] [--dump-log]
          [--dump-log-readable] [--remove-waiting] [--remove-wrong]
          [--db-file DB_FILE]

A status transporter from Mastodon to Twitter

optional arguments:
  -h, --help            show this help message and exit
  --config-file CONFIG_FILE
                    Using CONFIG_FILE instead of the default.
  --summary             Showing summary of log DB
  --trigger TRIGGER     Using TRIGGER instead of trigger in the config file
  --since SINCE         Using SINCE instead of since in the config file
  --until UNTIL         Using UNTIL instead of until in the config file
  --limit LIMIT         Using LIMIT instead of limit in the config file
  --dry-run             Getting the last status with the hashtag, but don't
                    send status to outbound service.
  --get-secret          Getting the access keys and others from Mastodon
                    instance and saving these in the config file.
  --dump-status-strings
                    Dumping status strings to be marked as 'Waiting'
                    status
  --dump-log            Dumping all records in the log database.
  --dump-log-readable   Dumping all records in the log database in a human-
                    readable format.
  --remove-waiting      Removing records in 'Waiting' from the database
  --remove-wrong        Removing records in 'Waiting' from the database
  --db-file DB_FILE     Using log DB_FILE instead of db_file of [result log]
                    section in the config file.

If some installation problems remain, you see the error message at above test.

For confirmation of dontwi.ini, run dontwi with --dry-run via:

[root@centos7 ~]# dontwi --dry-run
Test at 2018-02-17T14:04:05.826111+00:00 in:your_mastodon,4705377 out:, tag:どんつい

When first accessing to your Mastodon instance, dontwi saves the access keys in config.ini.

When you execute dontwi with --dry-run, dontwi gets a tag timeline of your Mastodon instance via Timelines API and prepares statuses to Twitter. dontwi prepares to post the oldest status in API response to Twitter, however, does not until post. This process is logged with 'Test' label. Other status texts are queued for next run with 'Waiting' label. While remaining in the queue, post one status from the queue on each run.

You can see the number of these labels in the log DB by --summary option via:

[root@centos7 opt]# dontwi --summary
dontwi version  1.0
log db  {'application': 'dontwi', 'version': '1.0'}
record number   25
Start   0
Waiting 23
Succeed 0
Failed  0
Test    2

Because labeled entries not specified with Waiting will not be processed, so delete the Test entries using --remove-wrong option before starting operation.:

[root@centos7 opt]# dontwi --remove-wrong

In this process, other failure-related entries will be deleted.

After the above preparation, you can test run. Simply execute dontwi:

[root@centos7 ~]# dontwi
Succeed at 2018-02-17T14:04:05.826111+00:00 in:your_mastodon,4705377 out:, tag:どんつい

4. Add dontwi entry to crontab

Let's add dontwi entry to crontab. Examaple is below:

*/2  *  *  *  * root       /usr/bin/dontwi

Above entry means run dontwi each 2 minute. Also, refer examples/crontab. If you prefer systemd, you can use examples/dontwi.service and examples/dontwi.timer.
