 # furry_giffer_bot_mastodon
-Mastodon Furry GIF poster
+
+**EN:** A Mastodon mention-bot that replies with animated media from **Furbooru** (Philomena API).  
+It tries to upload a GIF first (with size fallbacks) and, if your Mastodon instance rejects GIFs (e.g. resolution limits), it automatically converts GIF → **MP4** and uploads that instead.  
+For NSFW requests it posts with **CW + spoiler** and marks media as sensitive.  
+Works on **Windows** and Linux.
+
+**RU:** Бот для Mastodon, который отвечает на упоминания и прикрепляет анимированное медиа из **Furbooru** (Philomena API).  
+Сначала пробует залить GIF (с фолбэком на меньшие версии), а если инстанс отклоняет GIF (например из-за лимитов на разрешение) — автоматически конвертирует GIF → **MP4** и заливает MP4.  
+Для NSFW-запросов постит с **CW + спойлером** и отмечает медиа как sensitive.  
+Работает на **Windows** и Linux.

+
+## Features / Возможности
+
+- Reply to mentions: `@giffer cute fluffy tail`
+- Multi-tag queries: spaces/commas, quotes, negative tags  
+  - `cute fluffy tail` → `cute, fluffy, tail`  
+  - `"rainbow dash" -gore`
+- `nsfw` keyword enables NSFW mode:
+  - posts with `spoiler_text="NSFW"` and `sensitive=True`
+  - uses NSFW filter_id if configured
+- Furbooru search for **animated GIF** via Philomena API
+- Real upload to Mastodon
+- Waits for media processing (prevents 422 “processing not finished”)
+- GIF upload fallbacks: full → large → medium → small → thumb
+- If GIF rejected by instance: **auto-convert to MP4**
+- Auto ALT text from Furbooru tags
+- Rate-limit protection:
+  - per-user cooldown
+  - global token bucket
+- Persistent state (prevents replying twice after restart):
+  - saves last seen notification id + processed status ids
+- Logs to console + rotating file
+
+---
+
+## Requirements / Требования
+
+- Python 3.10+ recommended
+- Mastodon access token with permission to read notifications & post statuses/media
+- Optional: `ffmpeg` (or `imageio-ffmpeg` for bundled ffmpeg)
+
+---
+
+## Install / Установка
+
+### Windows (PowerShell or CMD)
+```bat
+py -m pip install --upgrade pip

+### Linux/macOS
+
+```bash
+python3 -m pip install --upgrade pip

+

+
+## Run / Запуск
+
+```bash
+python giffer_bot.py
+```
+
+The bot will continuously poll mentions and respond.
+
+---
+
+## Usage / Использование
+
+Mention the bot with tags:
+
+* `@giffer cute`
+* `@giffer cute fluffy tail`
+* `@giffer "rainbow dash" -gore`
+* `@giffer nsfw latex`
+
+NSFW mode is triggered if the word `nsfw` is present anywhere in the mention content.
+
+The reply will include an **original source link** (Furbooru page).
+
+---
+
+## Files / Файлы
+
+* `giffer_bot.py` — bot source code
+* `config.env` — configuration (not committed)
+* `giffer.log` — log file (rotating)
+* `giffer_state.json` — saved state to avoid double replies
+
+---
+
+## Notes / Примечания
+
+* If the bot starts replying to old mentions again, make sure `STATE_FILE` is not deleted.
+* Some Mastodon instances reject large GIFs. This is expected; the bot will try smaller representations and then MP4 fallback.
