func DetectRequirements ¶

func DetectRequirements(code string) string

DetectRequirements analyzes Python code and returns a requirements.txt string containing all detected third-party packages.

The function: 1. Parses import statements from the code 2. Filters out standard library modules 3. Maps module names to pip package names (e.g., PIL -> Pillow) 4. Returns a newline-separated list of packages

If no third-party packages are detected, an empty string is returned.

func GetPackageName ¶

func GetPackageName(module string) string

GetPackageName returns the pip package name for a given Python module. If no mapping exists, the module name is returned as-is (works for most packages).

func IsStdlib ¶

func IsStdlib(module string) bool

IsStdlib returns true if the module name is part of the Python standard library.

func MergeRequirements ¶

func MergeRequirements(detected, userProvided string) string

MergeRequirements merges auto-detected requirements with user-provided ones. User-provided requirements take precedence (appear first, may have version pins).

func ParseImports ¶

func ParseImports(code string) []string

ParseImports extracts all imported module names from Python code. It handles: - import X - import X as Y - import X, Y, Z - from X import Y - from X.submodule import Y

It ignores imports inside string literals and comments.
