Creating origins

[board] - board name, without "/"

[resource_type] must be a string like "( .img | .gif | webm )". For example, valid string is .img.gif

• .img will match image formats
• .gif will match gif format
• .webm will match video formats

[tags] must be in format [ ! ]"tag1"{ & | | }...

• & - means conjunction
• | - means disjunction
• ! - means negation

Matching is made using disjunctive normal form, i.e. first it calculates negation, than conjunction, disjunction is the last
For example, string "cats"|"dogs"&!"big" will match threads, description of which contains "cats" or "dogs", but not "big"

[display_name] is a string that will be visible to everyone when they call /list

Example: /create_default wp .img "wallpaper"&"desktop" Wallpapers

Configuring

Disk is used to save videos in .webm format to satisfy ffmpeg requirements (I use converting because telegram does not support this format). After sending, files will be deleted automatically.

In configs/config.yml:

• db - database configuration
• dapi - 2ch api, you can change it to use other mirrors or custom api
• tg.admin_id - list of admins telegram id
• disk:
  • path - relative or absolute path of directory, where files will be saved
  • size - max allowed space in bytes. Files, that extends this parameter, will be discarded
• polling - period of time in minutes, after which new threads will fetched

Environment variables:

• DB_PASSWORD - database password
• DB_PORT - database port
• BOT_TOKEN - your telegram bot token

Running

Run: docker-compose up
