# Custom Emoji
Before you add your own custom emoji, check if they are available in an existing pack.
See `Mix.Tasks.Pleroma.Emoji` for information about emoji packs.
To add custom emoji:
* Create the `STATIC-DIR/emoji/` directory if it doesn't exist
(`STATIC-DIR` is configurable, `instance/static/` by default)
* Create a directory with whatever name you want (custom is a good name to show the purpose of it).
This will create a local emoji pack.
* Put your `.png` emoji files in that directory. In case of conflicts, you can create an `emoji.txt`
file in that directory and specify a custom shortcode using the following format:
`shortcode, file-path, tag1, tag2, etc`. One emoji per line. Note that if you do so,
you'll have to list all other emojis in the pack too.
* Either restart pleroma or connect to the iex session pleroma's running and
run `Pleroma.Emoji.reload/0` in it.
Example:
image files (in `instance/static/emoji/custom`): `happy.png` and `sad.png`
content of `emoji.txt`:
```
happy, /emoji/custom/happy.png, Tag1,Tag2
sad, /emoji/custom/sad.png, Tag1
foo, /emoji/custom/foo.png
```
The files should be PNG (APNG is okay with `.png` for `image/png` Content-type) and under 50kb for compatibility with mastodon.
Default file extentions and locations for emojis are set in `config.exs`. To use different locations or file-extentions, add the `shortcode_globs` to your secrets file (`prod.secret.exs` or `dev.secret.exs`) and edit it. Note that not all fediverse-software will show emojis with other file extentions:
```elixir
config :pleroma, :emoji, shortcode_globs: ["/emoji/custom/**/*.png", "/emoji/custom/**/*.gif"]
```
## Emoji tags (groups)
Default tags are set in `config.exs`. To set your own tags, copy the structure to your secrets file (`prod.secret.exs` or `dev.secret.exs`) and edit it.
```elixir
config :pleroma, :emoji,
shortcode_globs: ["/emoji/custom/**/*.png"],
groups: [
Finmoji: "/finmoji/128px/*-128.png",
Custom: ["/emoji/*.png", "/emoji/custom/*.png"]
]
```
Order of the `groups` matters, so to override default tags just put your group on top of the list. E.g:
```elixir
config :pleroma, :emoji,
shortcode_globs: ["/emoji/custom/**/*.png"],
groups: [
"Finmoji special": "/finmoji/128px/a_trusted_friend-128.png", # special file
"Cirno": "/emoji/custom/cirno*.png", # png files in /emoji/custom/ which start with `cirno`
"Special group": "/emoji/custom/special_folder/*.png", # png files in /emoji/custom/special_folder/
"Another group": "/emoji/custom/special_folder/*/.png", # png files in /emoji/custom/special_folder/ subfolders
Finmoji: "/finmoji/128px/*-128.png",
Custom: ["/emoji/*.png", "/emoji/custom/*.png"]
]
```
Priority of tags assigns in emoji.txt and custom.txt:
`tag in file > special group setting in config.exs > default setting in config.exs`
Priority for globs:
`special group setting in config.exs > default setting in config.exs`
