# The .gitea directory
|
||||||
|
Gitea repositories can include a `.gitea` directory at their base which will store settings/configurations for certain features.
|
||||||
|
|
||||||
|
## Templates
|
||||||
|
Gitea includes template repositories, and one feature implemented with them is auto-expansion of specific variables within your template files.
|
||||||
|
To tell Gitea which files to expand, you must include a `template` file inside the `.gitea` directory of the template repository.
|
||||||
|
Gitea uses [gobwas/glob](https://github.com/gobwas/glob) for its glob syntax. It closely resembles a traditional `.gitignore`, however there may be slight differences.
|
||||||
|
|
||||||
|
### Example `.gitea/template` file
|
||||||
|
All paths are relative to the base of the repository
|
||||||
|
```gitignore
|
||||||
|
# All .go files, anywhere in the repository
|
||||||
|
**.go
|
||||||
|
|
||||||
|
# All text files in the text directory
|
||||||
|
text/*.txt
|
||||||
|
|
||||||
|
# A specific file
|
||||||
|
a/b/c/d.json
|
||||||
|
|
||||||
|
# Batch files in both upper or lower case can be matched
|
||||||
|
**.[bB][aA][tT]
|
||||||
|
```
|
||||||
|
**NOTE:** The `template` file will be removed from the `.gitea` directory when a repository is generated from the template.
|
||||||
|
|
||||||
|
### Variable Expansion
|
||||||
|
In any file matched by the above globs, certain variables will be expanded.
|
||||||
|
All variables must be of the form `$VAR` or `${VAR}`. To escape an expansion, use a double `$$`, such as `$$VAR` or `$${VAR}`
|
||||||
|
|
||||||
