Dosya Düzenle: index_format.txt

This file documents the index format that is read and written by this package.
The index format is an encoding of a series of RawPackage structs

Field names refer to fields on RawPackage and rawFile.
The file uses little endian encoding for the uint32s.
Strings are written into the string table at the end of the file.
Each string is prefixed with a uvarint-encoded length.
Bools are written as uint32s: 0 for false and 1 for true.

The following is the format for a full module:

“go index v2\n”
str uint32 - offset of string table
n uint32 - number of packages
for each rawPackage:
	dirname - string offset
	package - offset where package begins
for each rawPackage:
	error uint32 - string offset // error is produced by fsys.ReadDir or fmt.Errorf
	dir uint32 - string offset (directory path relative to module root)
	len(sourceFiles) uint32
	sourceFiles [n]uint32 - offset to source file (relative to start of index file)
	for each sourceFile:
		error - string offset // error is either produced by fmt.Errorf,errors.New or is io.EOF
		parseError - string offset // if non-empty, a json-encoded parseError struct (see below). Is either produced by io.ReadAll,os.ReadFile,errors.New or is scanner.Error,scanner.ErrorList
		synopsis - string offset
		name - string offset
		pkgName - string offset
		ignoreFile - int32 bool // report the file in Ignored(Go|Other)Files because there was an error reading it or parsing its build constraints.
		binaryOnly uint32 bool
		cgoDirectives string offset // the #cgo directive lines in the comment on import "C"
		goBuildConstraint  - string offset
		len(plusBuildConstraints) - uint32
		plusBuildConstraints - [n]uint32 (string offsets)
		len(imports) uint32
		for each rawImport:
			path - string offset
			position - file, offset, line, column - uint32
		len(embeds) uint32
		for each embed:
			pattern - string offset
			position - file, offset, line, column - uint32
		len(directives) uint32
		for each directive:
			text - string offset
			position - file, offset, line, column - uint32
[string table]
0xFF (marker)

The following is the format for a single indexed package:

“go index v0\n”
str uint32 - offset of string table
for the single RawPackage:
	[same RawPackage format as above]
[string table]

The following is the definition of the json-serialized parseError struct:

type parseError struct {
	ErrorList *scanner.ErrorList // non-nil if the error was an ErrorList, nil otherwise
	ErrorString string // non-empty for all other cases
}
