Command-line

- You can now control the symbol mapper used
- You can now set the verbosity level (no-oped currently)
- You can set the output filename
- You can set whether pretty code is to be used or not
- You can set whether or not to generate the entrypoint testing code during emit

Compiler
- Added new exception type `CompilerException` complete with a sub-type enum, `CompilerError`
- `getConfig()` will now throw a `CompilerException` when a key is not found, rather than return false (which didn't work under different template types anyways)
- Implemented `hasConfig()` to check for the existence of a key in the configuration sub-system's key-value store
- The `Compiler` object now stores the `Token[] tokens` generated from the call to `doLex()`
- The `Compiler` object now stores the resulting container (`Module`) generated from the call to `doParse()`
- Set default symbol mapping technique to the hashmapper technique
- Implemented `dolex()` for performing tokenization, it will create and store a `Lexer` instance and the produced `Token[] tokens` into the `Compiler` object
- Added `getTokens()` to fetch the tokens generated by `doLex()`
- Implemented `doParse()`, `doTypeCheck()` and `doEmit()` in a similiar fashion to `doLex()`
- Implemented `getMdoule()` to get the container (`Module`) generated by `doParse()`
- Implemented `compile()` which calls `doLex()`, then `doParse()`, then `doTypeCheck()` and finally `doEmit()`
CodeEmitter
- The `CodeEmitter` constructor now takes in an instance of the chosen `SymbolMapper`
DGen
- Switched to the instance of the `mapper` inheited from the `CodeMapper` parent class for any `symbolMap` calls required
- Use the inherited `TypeChecker` instance and not an instance of it provided by `Context`
SymbolMapper
- Reworked this class into an abstract class which must have its children implement a `symbolMap(Entity)` interface, this provides us pluggable mapping techniques
HashMapper
- Moved hashing symbol-mapping technique into `HashMapper`
Lebanese
- Created a kind-of `SymbolMapper` which, unlike `HashMapper`, produces human-redable-yet-valid C symbols (by replacing the `.`'s with `_`'s)
TypeChecker
- Removed code for setting now-nonexistent `SymbolMapper.tc`
- Removed code for setting now-nonexistent `Context.tc`
Context

- `getLinearizedNodes()` returns the `DNode[]` of the linearization results
` `getTree()` returns the string representation of the dependency tree
- New linearization method which requires calling `performLinearization()` before `getLinearizedNodes()` or `getTree()`, if not then an exception is thrown
- Made `tree()` private
- `tree()` now takes in argument `ref DNode[]` of which it will read the linerization into instead of `static DNode[] poes`
- Added comment regarding Problem 5 of issue #41
- Removed `static DNode[] poes`
TypeCheck
- Added better comments
- Switched to new linearization methods for both module-level processing and function definition (`FuncData`) processing
- Removed any reference to `DNode.poes`
- Moved configuration sub-system to its own class `CompilerConfiguration`
- `getConfig()` and `setConfig()` are now templatised to generate, at compile-time, type-specific versions which will fetch and convert using the requested type
- Added some more default configuration parameters for DGen
DGen
- Implemented configuration checking for `genTabs()` and `emitEntryPoint()` (both which have the default config value of `true`)
- Added commented-out testing code (see issue #88)
- Added missing `typeChecker.beginCheck()` call to the TypChecker in `compile()`
- Print error on lexing error
- Removed old compilation code and replaced with an instantiation of a `Compiler` object and a corresponding call to `.compile()`
- Added comments and removed TODO for now complete feature on `parseTypedDeclaration()`
Dependency
- Added support for external variable symbols to `transform()` for declarations, assignments and variable expressions
Test cases
- Updated extern evar test case to new symbol name that wouldn't clash
- Added assignment usage and expression usage
- `parseTypedDeclaration()` will no longer consume the SEMICOLON after a vardec
- `parseTypedDeclaration()` will no longer consume theSEMICOLON after an assignment
- `parseName()` will expect a semicolon if the returned object from `parseTypedDeclaration()` is of type `Variable`. If of type `Function` then nothing will be expected
- Added `allowVarDec` and `allwFuncDef` to `parseTypedDeclaration()` as default arguments with `true` as their default values
- If `allowFuncDef` is true then parse a function
- If `allowVarDec` is `true` then allow a variable definition
- If `allowVarDec` is true but we have an assignment and `wantsBody` is false then throw an error
- NOTE: A fix for `parseTypedDeclaration()` is needed for this to work
Tests
- Updated `simple_extern.t` to include an `extern evar`
- Implemented type `Compiler` which wraps compilation all into one object which can have `compile()` called on it to perform the full sequence of tests
- 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)
- In `emitFunctionDefinitions()` do not emit a function body at all (or anything, no signature) if the `Function` is marked as external (`isExternal()` is true)
- Added entry point test for `simple_extern.t`
- Added `getReferType()` to `Pointer` type to refer the `Type` instance of the data being pointed to
DGen
- Fixed bug whereby pointer types were not being transformed correctly in typeTransform()`

Check
- Added backmapping for `SymbolType.ASSIGN` -> `&`
