###Module ###Aliases.nim - Alias Analysis Used for term-rewriting macros. Buggy for this purpose because it has been rewritten with something completely different in mind. Analysis is both value and type based. Looks for areas
###Ast.nim Tree structure
###Astalgo contains helpers and debug procedures, which work on symbols, types, and node.
###babel.cmd helper for compilers babel support
###bitsets Helpers for code generator. Set representation as an array of bits
###nimsets.nim - The complement to bitsets. Set representation as an AST
###Canonicalizer Will be the future. Used to make the C code generator generate code in a much more deterministic fashion.
###ccgcalls C code generator calls. Generates a call expression in C, objective c, and C++ syntax. What needs to be done is that we often need to translate the result type into a hidden parameter.
###cggexpr
C code generation for expressions. Divide between stmts and expr mostly historical
###ccgmerge
A merger for C files which is used for the symbol files feature.
###ccgstmts Code generation for statements. See ccgexprs. NOt for for loops, b/c they are eliminated.
###ccthreadvars Thread variable emulation.
###ccgtypes complex, b/c deals with types. The PNode's are not cyclic. You can recurse them without any recursion checks. Type generation for the c backend, as well as run time type generation.
###ccgutils Misc. utilities for C generation code. Contains hash string. Has to be same as system hash string, generate hashes at compile time. Also contains getUniqueType, to be deprecated in place of the canonicalization module.
###cgen.nim Main file for the C code generation. Includes things like DLL generation, foreign function interface, dispatches to. Cgendata is the main structure.
###cgmeth.nim code generation for methods. Performs AST to AST transformations. Analysis away method look up.
###commands.nim Command line argument processing.
###condsyms conditional symbols
###crc.nim cyclic redundancy check algorithm. Used by symbol files, recom
###depends.nim Pass which computes dependancies between modules. Able to generate a dot file which can be used.
###docgen.nim Old documentation generator, which doesn't use the semantic pass. Doesn't know about symbols and identifiers.
###docgen2.nim New documenation generator
###effects.nim - ###evalffi.nim -
###evals.nim old evaluation engine, not used anymore
###exccomp external compiler, describes how the c compiler is invoked.
###filter_template hashbang filter
###filters helper for common stuff which source code filter.
###syntaxes.nim -
###guards - Growing module. Flow sensitive analysis, mainly for values. Used for not nil checking
###hlo - High level optimizer. Part of the term-rewriting macro engine.
###idents.nim - PIdents. Hash identifiers into a single global hash table
###idgen - ID generator. Used to create persistant IDs for the symbol files mechanism
###imports.nim - The module which has the helpers which deal with the module import mechanism.
###jsgen - Javascript code generator
###lambdalifting - Pass which changes closures into pairs of function pointers and environments
###lexer - the lexer
###lists - Linked list implementation
###llstream - low level stream which contains some features which the compiler needs.
###lookups.nim - helpers for symbol lookup. Quite involved due to templates, overloading, etc.
###lowerings - Quite new module which implements common AST to AST helpers.
###magicsyms - compilerproc symbol is used by code generator whic inse
###modules.nim - Module handling
###message.nim - Messages, warnings, hints.
###nimconf - configuration file handling
###nimeval - the upcoming virtual machine to evaluate code.
###nimlexbase - Old lexbase. Buffer handling fo rthe lexer.
###nimrod.nim - Main nimrod file which produces the nimrod executable.
###options - Contains commandline options and checks.
###parampatterns - Related to overloading based on AST
###parseaux - auxileries for the parser. Contains verbosity handling.
###sempass2 - additional semantic checking.
###patterns - related to term rewriting macros
###pbraces - start of braces parser
###platform.nim - contains information for cross compiling (data type information)
###pragmas.nim - Contains all the pragmas that the compiler support. Use a set approach. Contains one big procedure which parses all the possible pragmas.
###pretty.nim - Prettifier. Used for case consistancy
###procfind - used to find the header of a procedure. Used to determine if
###renderer - able to give a string representation in the AST.
###rodread - Reader of rod files, the symbol file mechanism
###rodutils - utilities for above
###ropes - Used throughout the code generator
###seterate.nim - Implements saturated arithmatic for integers.
###sem.nim - Main file for the semantic checker
###semcall - semantic checking for calls
###semdata - contains the main data structures for semantic checking.
###semdestruct - semantic checking for destructors.
###semexprs - semantic checking for expressions.
###semfold - semantic checking for constant folding. Needed in the semantic pass, since things like bounds checking etc rely on such data.
###semgnrc - pass which implements symbol lookups for generics.
###seminst - instantiation of generics
###macrosanity - generates semantic ast checking for macros
###semmagic - magics that need special treatment after overloading resolution.
###semparallel - semantic checking for the upcoming parallel statement
###sempass2 - Effect tracking
###service.nim - IDE Tool stuff
###sigmatch - very important module. Overloading resolution procedures.
###suggest.nim - helper for IDE tools
###syntaxes - dispatching for what parser or sourcecodefilter to invoke.
###transf - old transformation pass. Prepass before the code generator. Mostly deals with for loops into while loops
###trees.nim - Helper for ast (should get rid of)
###treetab - hashtable which works with trees
###types - helper for types
###typesrenderer - new. Used for the documentation generator so we get names
###vm.nim - new virtual machine for compile time evaluation
