1 ============
2 These pieces of code were ported from dotnet/corefx:
3
4 syntax/charclass.go (from RegexCharClass.cs): ported to use the built-in Go unicode classes. Canonicalize is
5 a direct port, but most of the other code required large changes because the C# implementation
6 used a string to represent the CharSet data structure and I cleaned that up in my implementation.
7
8 syntax/code.go (from RegexCode.cs): ported literally with various cleanups and layout to make it more Go-ish.
9
10 syntax/escape.go (from RegexParser.cs): ported Escape method and added some optimizations. Unescape is inspired by
11 the C# implementation but couldn't be directly ported because of the lack of do-while syntax in Go.
12
13 syntax/parser.go (from RegexpParser.cs and RegexOptions.cs): ported parser struct and associated methods as
14 literally as possible. Several language differences required changes. E.g. lack pre/post-fix increments as
15 expressions, lack of do-while loops, lack of overloads, etc.
16
17 syntax/prefix.go (from RegexFCD.cs and RegexBoyerMoore.cs): ported as literally as possible and added support
18 for unicode chars that are longer than the 16-bit char in C# for the 32-bit rune in Go.
19
20 syntax/replacerdata.go (from RegexReplacement.cs): conceptually ported and re-organized to handle differences
21 in charclass implementation, and fix odd code layout between RegexParser.cs, Regex.cs, and RegexReplacement.cs.
22
23 syntax/tree.go (from RegexTree.cs and RegexNode.cs): ported literally as possible.
24
25 syntax/writer.go (from RegexWriter.cs): ported literally with minor changes to make it more Go-ish.
26
27 match.go (from RegexMatch.cs): ported, simplified, and changed to handle Go's lack of inheritence.
28
29 regexp.go (from Regex.cs and RegexOptions.cs): conceptually serves the same "starting point", but is simplified
30 and changed to handle differences in C# strings and Go strings/runes.
31
32 replace.go (from RegexReplacement.cs): ported closely and then cleaned up to combine the MatchEvaluator and
33 simple string replace implementations.
34
35 runner.go (from RegexRunner.cs): ported literally as possible.
36
37 regexp_test.go (from CaptureTests.cs and GroupNamesAndNumbers.cs): conceptually ported, but the code was
38 manually structured like Go tests.
39
40 replace_test.go (from RegexReplaceStringTest0.cs): conceptually ported
41
42 rtl_test.go (from RightToLeft.cs): conceptually ported

68 ============
69 These pieces of code are copied from the Go framework:
70
71 - The overall directory structure of regexp2 was inspired by the Go runtime regexp package.
72 - The optimization in the escape method of syntax/escape.go is from the Go runtime QuoteMeta() func in regexp/regexp.go
73 - The method signatures in regexp.go are designed to match the Go framework regexp methods closely
74 - func regexp2.MustCompile and func quote are almost identifical to the regexp package versions
75 - BenchmarkMatch* and TestProgramTooLong* funcs in regexp_performance_test.go were copied from the framework
76 regexp/exec_test.go
