title: declare_static
description: API reference for the declare_static function
---

## Overview

`declare_static` marks content as statically analyzable so that the GT CLI can extract all possible translation entries at build time.

It is an **identity function** — it returns exactly what you pass in. Its purpose is as a marker for static analysis.

```python
from gt_flask import declare_static, t  # or from gt_fastapi

message = t(f"The {declare_static('boy' if gender == 'male' else 'girl')} is playing.")
```

## Reference

### Parameters

<TypeTable
  type={{
    "content": {
      type: 'object',
      description: 'A static expression with a finite set of possible values.',
    },
  }}
/>

### Returns

Returns `content` unchanged. The function is an identity — its purpose is as a marker for the CLI.

## Notes

- All possible outcomes must be statically analyzable at build time
- Dynamic content (user input, API data) inside `declare_static` should be wrapped with [`declare_var`](/docs/python/api/declare-var)
- Use [`decode_vars`](/docs/python/api/decode-vars) to extract original values from declared variables
- See the [declare_static tutorial](/docs/python/tutorials/declare-static) for detailed examples and usage patterns
