func ParseEnv ¶

func ParseEnv(envFilePath, key string) (string, error)

ParseEnv implements a strict parser for environment files using a subset of POSIX shell syntax. The parser enforces that all variable values must be enclosed in single quotes.

Supported format:

• VAR='value' - Values must be enclosed in single quotes
• Content within single quotes is preserved literally (no escape sequences or expansions)
• Multi-line values are supported (newlines within single quotes are preserved)
• Inline comments after the closing quote are supported (e.g., VAR='value' # comment)
• Leading whitespace before the variable name is ignored
• Blank lines (including those with only whitespace) are ignored when not within quotes
• Lines starting with '#' are treated as comments and ignored
• Whitespace before '=' is invalid (e.g., VAR = 'value' is rejected)
• Whitespace after '=' but before the quote results in empty assignment (e.g., VAR= 'value' assigns empty string)
