Overview

Parses XCRemoteSwiftPackageReference entries from a project.pbxproj file to extract dependency requirement constraints declared in Xcode.

Returns a hash keyed by normalized dependency name (e.g. “github.com/owner/repo”) mapping to requirement metadata, so the main parser can enrich Package.resolved dependencies with requirement info from the Xcode project.

Constant Summary collapse

PACKAGE_REF_BLOCK =

Regex to extract XCRemoteSwiftPackageReference blocks from pbxproj. Uses [^}]* to match the requirement block content — this is safe because Xcode requirement blocks are always flat dictionaries with no nested braces.

T.let(
  /
    isa\s*=\s*XCRemoteSwiftPackageReference;\s*
    repositoryURL\s*=\s*"(?<url>[^"]+)";\s*
    requirement\s*=\s*\{(?<requirement>[^}]*)\};
  /mx,
  Regexp
)
KIND_PATTERN =

Patterns for extracting requirement fields

T.let(/kind\s*=\s*(\w+);/, Regexp)
VERSION_NUMBER_PATTERN = 
T.let(/[0-9A-Za-z.+-]+/, Regexp)
MIN_VERSION_PATTERN = 
T.let(/minimumVersion\s*=\s*(#{VERSION_NUMBER_PATTERN});/, Regexp)
MAX_VERSION_PATTERN = 
T.let(/maximumVersion\s*=\s*(#{VERSION_NUMBER_PATTERN});/, Regexp)
VERSION_PATTERN = 
T.let(/version\s*=\s*(#{VERSION_NUMBER_PATTERN});/, Regexp)
BRANCH_PATTERN = 
T.let(/branch\s*=\s*"?([^";]+)"?;/, Regexp)
REVISION_PATTERN = 
T.let(/revision\s*=\s*"?([^";]+)"?;/, Regexp)
