# `PhoenixKit.Install.RuntimeDetector`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v1.7.165/lib/phoenix_kit/install/runtime_detector.ex#L1)

Detects Phoenix runtime configuration patterns and determines appropriate config strategy.

This module analyzes Phoenix project configuration files to determine:
- Whether the project uses runtime.exs patterns
- The appropriate configuration file to modify
- The correct insertion location for PhoenixKit configuration

# `detect_config_pattern`

Detects if the project uses runtime configuration patterns.

## Returns

- `:runtime` - Uses runtime.exs with conditional blocks
- `:dev_exs` - Uses simple dev.exs file
- `:config_exs` - Uses config.exs with environment variables

## Examples

    iex> RuntimeDetector.detect_config_pattern()
    :runtime

# `dev_exs_exists?`

Checks if dev.exs file exists.

## Returns

`true` if dev.exs exists, `false` otherwise.

# `find_insertion_point`

Finds the appropriate insertion point for PhoenixKit configuration.

## Returns

- `{:runtime, line_number}` - Insert at specific line in runtime.exs
- `{:dev_exs, line_number}` - Insert at end of dev.exs
- `{:config_exs, line_number}` - Insert in config.exs with env check

## Examples

    iex> RuntimeDetector.find_insertion_point()
    {:runtime, 76}

# `find_runtime_insertion_point`

Finds the appropriate location within runtime.exs for development configuration.

## Returns

`line_number` where PhoenixKit config should be inserted.

# `has_runtime_patterns?`

Checks if runtime.exs contains runtime configuration patterns.

## Returns

`true` if runtime patterns are detected, `false` otherwise.

# `runtime_exists?`

Checks if runtime.exs file exists in the project.

## Returns

`true` if runtime.exs exists, `false` otherwise.

# `simple_dev_config?`

Checks if dev.exs file exists and is simple enough to modify.

## Returns

`true` if simple dev.exs exists, `false` otherwise.
