9:00build.bat: Add simple_preprocessor.cpp

9:45Debugger: Step into simple_preprocessor.cpp and ensure that it works as expected

10:51simple_preprocessor.cpp: Null terminate the file

11:19handmade.h: #define introspect

12:31handmade_sim_region.h: Use this introspect macro

12:42Brown butter^α

13:16Describe tokens

14:58simple_preprocessor.cpp: Introduce token structures

16:41simple_preprocessor.cpp: Loop over the Tokens and print them out

20:18simple_preprocessor.cpp: Introduce struct tokenizer

21:20simple_preprocessor.cpp: Introduce EatAllWhitespace

23:09Get a little brained^β

28:06simple_preprocessor.cpp: Provide a way to parse identifiers

29:20simple_preprocessor.cpp: Move GetToken's functionality to the correct place and write EatAllWhitespace

31:13simple_preprocessor.cpp: Provide the ability to parse C-style comments and introduce IsEndOfLine

34:36simple_preprocessor.cpp: Introduce IsAlpha and IsNumeric

35:57simple_preprocessor.cpp: Handle unknown tokens

37:00simple_preprocessor.cpp: Skip the closing quote

38:47simple_preprocessor.cpp: Implement ParseIdentifier

40:09Debugger: Step into simple_preprocessor.cpp and inspect the Tokenizer

41:07simple_preprocessor.cpp: Handle skipping over the first character

42:33Debugger: Step back in and inspect the Token

43:30Run the preprocessor and look at its output

44:09simple_preprocessor.cpp: Introduce ParseIntrospectable

45:29simple_preprocessor.cpp: Introduce TokenEquals

48:08Debugger: Step in to TokenEquals

48:51simple_preprocessor.cpp: Check for the string "intr"

49:37Debugger: Step through the loop inspecting At and Index

50:51simple_preprocessor.cpp: Implement ParseIntrospectable

53:11simple_preprocessor.cpp: Introduce ParseIntrospectionParams

53:54simple_preprocessor.cpp: Introduce ParseStruct

55:17simple_preprocessor.cpp: Introduce ParseMember

56:04simple_preprocessor.cpp: Introduce RequireToken

56:59simple_preprocessor.cpp: Provide the ability to print out the DEBUG_VALUE

1:00:43Run the preprocessor and see what happens

1:18:39cvaucher I'm writing a parser that looks pretty similar to this, but it runs on multi-GB files which takes a while. Any common approaches to use SIMD/multithreading to speed up text parsing? Seems more difficult since the characters aren't "independent" in the way pixels are
