Function parse_pkgbuild_conflicts 

pub fn parse_pkgbuild_conflicts(pkgbuild: &str) -> Vec<String>

What: Parse conflicts from PKGBUILD content.

Inputs:

• pkgbuild: Raw PKGBUILD file content.

Output:

• Returns a vector of conflicting package names (without version constraints).

Details:

• Parses bash array syntax: conflicts=('foo' 'bar') (single-line)
• Also handles conflicts+= patterns used in functions like package()
• Handles both quoted and unquoted conflicts
• Also handles multi-line arrays:

  conflicts=(
      'foo'
      'bar'
  )

• Filters out .so files (virtual packages) and invalid package names
• Extracts package names from version constraints (e.g., “jujutsu-git>=1.0” -> “jujutsu-git”)
• Deduplicates conflicts (returns unique list)
