- Corrected import path for `compiler.lexer` -> `compiler.lexer.core`
Parser

TypeChecker
- Corrected import path for `compiler.lexer` -> `compiler.lexer.core`
Compiler
- Moved configuration code outside of it
- Renamed to `compiler.core`
DGen
- Check for any object files to link in, if so append them to the `cc` call
Lexer
- Moved from `compiler.lexer` to `compiler.lexer.core`
Configuration
- Overhauled configuration system
Mapper
- Added definition to `SymbolMappingTechnique`
Command-line
- Migrated to new configuration system
- Migrated `SymbolMappingTechnique` to Mapper module
- Added support for specifying object fils to link in using the `-ll` flag`
Tests
- Added `file_io.c` for testing `simple_extern.t` with `extern_test.sh`
- Added `extern_test.sh` for testing `simple_extern.t`
- Added new symbol types `EXTERN`, `EXTERN_EFUNC` and `EXTERN_EVAR` and related back-mappings
Parser
- `parseFuncDef()` now accepts a default argument (set to `true`) on whether to expect a body for a function or not, in the not case expect a semi-colon - this helps with extern support
- Likewise because `parseFuncDef(bool wantsBody = true)` is called by `parseTypedDeclaration()` we have added same argument to `parseTypedDeclaration(bool wantsBody = true)`
- Ensure we pass the parameter from `parseTypedDeclaration()` into `parseFuncDef(bool)` in function definition case
- Implemented `parseExtern()` for extern support
- `parse()` supports `SymbolType.EXTERN` now
Data
- Added `ExternStmt` to represent the parser node derived from a call to `parseExtern()`
- The `Entity` parser node type now has an `isExternal()` flag to know if the entity is marked for `extern` link time or TLang internal time (default)
Typechecker
- Implemented `processPseudoEntities(Container)` which loops through the given container and finds all extern statements and then extracts those nodes, parents them to the given container and marks them as external (pseudo-handling support)
- Added first call inside `beginCheck()` to be a call to `processPseudoEntities(modulle)`
Dependency
- Added useless no-op check for `ExternStmt` - it does nothing
DGen
- In `emitFunctionSignature()`, prepend the string `extern ` to the signatur if the given `Function` entity is marked as external (`isExternal()` is true)

- Added support for pointer dereferncing assignments with the addition of `parseDerefAssignment()`
- `parseStatement()` will now call `parseDerefAssignment()` on occurence of a `SymbolType.STAR`
- Added a unittest for testing pointers
- Finished unittest for for loops
Check
- Added backmapping for `SymbolType.ASSIGN` -> `&`
Data
- Added new parser node type `PointerDereferenceAssignment` for pointer support in the parser
TypeChecker
- Because function parameters are type che cked upon function call I had to add typechecking code for pointer support in the `UnaryOperatorExpression` case
- Added code generation support for `PointerDereferenceAssignment` type
Dependency
- Added support for `PointerDereferenceAssignment` type (pointer support) to `generalStatement()`
Tests
- Added pointer test `simple_pointer.t`
- Added a new instruction, `ForLoop`, which contains a pre-run Instruction and a `Branch` instruction, coupled with some flags
DGen

- Implemented C code emitting in `emit()` for `ForLoop` instruction
Check
- Added missing back-mapping for `SymbolType.SMALLER_THAN`

- `parseStatement()` can now have the terminating symbol specified, defaults to `SymbolType.SEMICOLON`
- `parseName()` and `parseAssignment()` now also accept a terminating symbol parameter as per `parseStatement()`'s behavior
- `parseBody()` now makes multiple calls to `parseStatement()` for singular Statement parsing (dead code below still to be removed)
- Removed commented-out unittests
- Unittests that read from files now have the file source code embedded
- Added unit test for while loops, for-loops (unfinished) and some other smaller language constructs (roughly 70% coverage)

- Added unit test for flushing fix
VariableDeclaration (Instruction)
- Added support for the embedding of a VariableAssignmentInstr inside (added a getter too) (a part of issue #66)
- Conditional support for if statements: Added two new instructions (IfStatementInstruction and BranchInstruction). See issue #64
DGen
- Added depth increment/decrement on enter/leave scope of `transform()`
- Correct tabbing for nested if-statements using new method `genTabs(ulong)` (which uses the above mechanism). Makes code emitted for if statements (issue #64) look nicer.
- Updated VariableDeclarations (with assignments) handling in `transform()` in the manner similar to BinOpInstr (see issue #66)
- Added a TODO for formatting BinOpInstr's `transform()` a little more aesthetically nicer
- Added code emitting support for if statements (the `IfStatementInstruction` instruction) (see issue #64)
- Updated `emitEntryPoint()` to only emit testing C code for the correct input test file
Parser
- `parseIf()` now returns an instance of IfStatement which couples multiple `Branch` objects consisting of `Statement[]` and `Expression`
- Ensured that each `Statement` of the generated `Statement[]` from `parseBody()` for a given `Branch` is parented to said Branch using `parentToContainer()`
- Ensured each generated `Branch` in `Branch[]` is parented to the generated `IfStatement` using `parentToContainer()`
- `parseBody()` now adds to its `Statement[]` build-up array the generated `IfStatement` from the call to `parseIf()`
Check
- Added support for back-mapping `SymbolType.EQUALS` to `getCharacter(SymbolType)`
Data
- Added `Branch` parser node which is a Container for body statements (`Statement[]`)
- Added `IfStatement` parser node which is a Container of `Statement[]` which are actually `Branch[]`

- Fixes handling of `StaticVariableDeclaration` and `VariableAssignmentNode` (fixes issue #66)
- Added handling for IfStatement entities (if statement support #64)
Resolution

Dependency
- Added a default `toString()` to the DNode class which prints `[DNode: <entity toString()]`
- Added a TODO and debug print related to issues #9
- Disabled InitScope.STATIC check for now as it caused issues with if statement parsing (probably due to VIRTUAL being default and therefore skipping if statment processing) - issue #69
- Cleaned up handling of Entity type `Variable` (variable declarations) - removed repeated code
- Undid the VarAss->(depends on)->VarDec, reverted back to VarDec->(depends on)->VarAss, fixed by #66 (and closes it and #11)

- Added `getInitQueue()` method to make a copy of the current "scratchpad" `codeQueue`
- Build up a copy of the global queue now (make a copy similiar to what we did for `getInitQueue()` but inline)

- Added a TODO relating to `static DNode[] poes`
Test cases
- Added test case `simple_function_decls.t` to test function definition code emit

README
- Build instructions now generate coverage files (`.lst`s)
- Updated link to documentation
- VariableAssignment entity now has its Context object set to the current Context (of the Variable being declared) (so this is a declare assignment case only (so far)) (fixes#36)
TypeChecker
- Extract the Context object from the VariableAssignment entity and then set it as the Context for the VariableAssigmnetInstr instruction (fixes#36)
VariableAssigmnentInstr
- The `emit()` method will now emit the assignment code
Check
