Hotfix/jcli upgrade fix (#24) * 🐞️ isSameType: Add a base case (#8) * Core - Added a TODO where we are meant to insert the fallback check in `isSameType(Type t1, Type t2)` * TypeChecker - Added backported `isSameType(Type 1, Type t2)` fix for #114 * 🐞️ Functions: Return position enforcement (#6) * Parser - Added a TODO in `wantsBody == true` case in `parseFuncDef()` to check for the return keyword's position * Parser - Added a check in `parseFuncDef()` which, is a `ReturnStmt` is found, then crash the parser if it is found anywhere besides the last statement * Test cases - Added test cases to test the `return` statement position enforcement * 🧠 Feature: Direct function calls (#11) * Test cases - Added `simple_direct_func_call.t` to test direct function calls * Test cases - Removed tabs which broke lexing * AST nodes - `FunctionCall` now has the ability to be marked as statement-level by calling `makeStatementLevel()`, this can then be queried later via `isStatementLevelFuncCall()` * Parser - Statement-level function calls were never actually returned, resulting in `null` being returned by `parseName()` - this has now been fixed. - Along with this we now "mark" this `FunctionCall` AST node as statement-level when it occurs in `parseName()` * Instruction - Allow `FuncCallInstr` to be makred as statement-level and queired much in the same manner as its corresponding AST-node/parser-node `FunctionCall` * Dependency - Added support for `DNode` generation in `generalPass()` for `FunctionCall` AST nodes * TypeChecker - Handle `FunctionCall`s differently in terms of code generation dependent on whether or not rhe call is within an expression of statement-level * DGen - Handle statement-level function calls (`FuncCallInstr`s) differently by tacking on an additional `";"` to the emit string * - Added `simple_direct_func_call.t` to GitHub pipeline * DGen - Added instrumentation for semantic code generation for `simple_function_recursion_factorial.t` - Added TODO for future `simple_func_call_direct.t` Test cases - Added `simple_function_recursion_factorial.t` to test recursion Pipelines - Added `simple_function_recursion_factorial.t` to `emit` stage * DGen - Made `if` an `else if` - this wouldn't of affected anything but just to be correct * DGen - Added semantic code generation instrumentation for test case `simple_direct_func_call.t` Test cases - Updated test case `simple_direct_func_call.t` * 🧠 Feature: Meta-programming engine (#10) * Parser - Added new interface `Cloneable` * Symbols - Added new `Statement`-based type: `Macro` to support `Macro`(s) * MetaProcessor - Added the `MetaProcessor` TypeChecker - Added the `MetaProcessor` instance to the `TypeChecker`, it will be instantiated upon the `TypeChecker`'s construction and later have its `.process()` method called as the first call in `beginCheck()` * TypedEntity - Added a `setType(string)` method to update the internal `type` field * MetaProcessor - Added a type-re-writing facility via `typeRewrite(TypedEntity)` which will re-write the types such as `size_t`, `ssize_t` and so forth Test cases - Added a test case `meta/types.t` which tests this * MetaProcessor - Updated the constructor to only take in an instance of the `TypeChecker` - Updated the `process()` method to take in a `Container` such that it can be used recursively - Commented code - Added a recursive call to `process(Container)` when `curStmt` is a kind-of `Container` (this ensures that we reach the `VariableParameter`s of `Function` (die to them making up the `Statement[]` of `Function` type) - Removed unused `cmp` import `std.string` - Added type-rewrite for `ssize_t` -> `long` TypeChecker - Updated the constructor call to `MetaProcessor` to use its new API - Updated call to `process()` to now be `process(modulle)` Test cases - Updated `types.t` to test re-writing of the `Function`'s parameters * MetaProcessor - Added another FIXME * Mcro - Added interface `MTypeRewritable` to represent any AST node which has a `setType(string)` and `string getType()` method for rewriting- Added `Sizeof` which is a kind-of `IntegerLiteral` Data - Made `TypedEntity` implement the `MTypeRewritable` interface Expressions - Made `IntegerLiteral` non-final such that we can inherit from it - Added a final `setNumber(string)` method to `NumberLiteral` to update the literal MetaProcessor - The type rewriting mechanism now operates on `MTypeRewritable` AST nodes - Work has begun on `sizeOf_Literalize(Sizeof)` which is to determine the `Type` of the `Sizeof` statement and then calculate the memory width and update its literal (as it is a kind-of `NunberLiteral`) to said size Test cases - Added `meta/sizeof.t` to test `sizeof` functionality * Mcro - Added interface type `MStatementSearchable` * Mcro - Redefined `MStatementSearchable` - Added `MStatementReplaceable` - Added `Repr` (a kind-of `Expression`) which will be used as an example to test out the aforementioned two interfaces * MStatementSearchable - Added method `search(TypeInfo_Class clazzType)` which uses a `TypeInfo_Class` to search for all types matching that (and which are sub-types of `Statement` and then adds these to a list and returns it in the form of `Statement[]` * MStatementReplaceable - Implemented `replace(Statement thiz, Statement that)` which replaces the `Statement` in the first argument with that of the `Statement` in the second argument * MStatementSearchable - Added documentation for `search(TypeInfo_Class)` method * Mcro - Made `Repr` implement `MStatementSearchable` - Added new interface `MCloneable` to represent PNode's which are deeply-cloneable * Data - Made `DiscardStatement` searchabe via implementing `MStatementSearchable` - Added a stub override for implementing `MStatementReplaceable` in `DiscardStatement` * Mcro - Updated `MStatementReplaceable` to have its `replace(Statement, Statement)` method return a boolean `true` if the replacement was successful, else `false` * Parsing - Added the ability to parse a `Repr` statement Check - Added `GENERIC_TYPE_DECLARE` and `REPR` as new `SymbolType`(s) Data - `DiscardStatement` now implements the `bool replace(Statement, Statement)` method MetaProcessor - Added the ability to replace statements that occur within any _other_ statements which implement `MStatementSearchable` and `MStatementReplaceable` Test cases - Added `meta/simple_meta_replace.t` to test all of this Diagrams - Added diagram on how the meta system works * MetaProcessor - Removed unused `replace` method * MetaProcessor - Accept a new argument to the `MetaProcessor(TypeChecker)` constructor indicating whether or not the `MetaProcessor` is enabled or not TypeChecker - Enable the `MetaProcessor` * Mcro - Removed `Sizeof`, we will let it be parsed as a normal `FunctionCall` and then inspect in `MetaProcessor` * MetaProcessor - Disabled `sizeOf_Literalize` for now - Search for all `FunctionCall` statements in `process(Container)` * MetaProcessor - Removed old code for testing `MStatementSearchable` and `MStatementReplaceable` - Added note that we will have to investigate a recursive `MTypeRewritable` to be able to support things like `sizeof(size_t)` - Implemented module-level `sizeof(<ident_type>)` support - Added `Number`-kind of types support to `sizeOf_Literalize`(string)` Containers (`Module`) - Added `MStatementSearchable` and `MStatementReplaceable` support to `Module` container type Data -

Implemented the `search` method for `MStatementSearchable` - Implemented the `replace` method for `MStatementReplaceable` * MetaProcessor - Added a future TODO for occurence of certain types that are alises (i.e. `size_t` appearing in a expression context like `sizeof(size_t)` - Now that all `Container`-based types are `MStatementReplaceable` we no longer need this check * MetaProcessor - Removed `break` which caused only one `sizeof()` function call to be replaced, we should have been looping over each `FunctionCall` found with `search` and then replacing ech that had a name of `sizeof` with a `NumberLiteral` expression - Moved all type alias replacement code into a new method; `doTypeAlias(Container, Statement)` - Added some rudiementary support for replacing any `IdentExpression` containing `size_t` with `uint` IdentExpression - Made it `MStatementSearchable` and `MStatementReplaceable` Test cases - Updated test case `meta/sizeof.t` to test the `sizeof(<expr>)` AST node in the `MetaProcessor` Documentation - Added diagram showing the `MStatementSearchable` and `MStatementReplaceable` in action * Compiler - If the T compiler was built on `X86` then set the maximum width to 4 bytes - If the T compiler was built on `X86_64` then set the maximum width to 8 bytes - Pass in the `Compiler` instance to the `TypeChecker` in `doTypeCheck()` TypeChecker - Added `Compiler` field and now accept it in constructor - If just single parameter constructor then pass in `null` as the `Compiler` instance - Added `getCompiler()` to get the instance MetaProcessor - Extract the `CompilerConfiguration` via the `TypeChecker`'s `getCompiler()` - Implemented `getSystemType(string)` which will map `size_t`/`ssize_t` to the correct maximum width'd type your system supports via the `types:max_width` config entry * CompilerConfiguration - Added `defaultConfig()` * Compiler - Removed `defaultConfig()` - During construction call `CompilerConfiguration.defaultConfig()` in order to generate the default config - Pass the config into `TypeChecker` in `doTypeCheck()` * TypeChecker - No longer store a field for the `Compiler` but rather store a field for the `CompilerConfiguration` - Removed single parameter constructor for `TypeChecker` - Constructor now uses the default `CompilerConfiguration` if not specified; therefore fixing the issue with unit tests failing MetaProcessor - Extract the compiler configuration via `tc.getConfig()` - Updated `typeRewrite(MTypeRewritable)` to use `getSystemType(string)` to lookup concrete types for `size_t`/`ssize_t` - `doTypeAlias(Container, Statement)` now uses `getSsstemType(string)` to lookup the concrete types for alises such as `size_t`/`ssize_t` * MetaProcessor - Implemented `isSystemType(string)` which returns `true` if the provided type is a system type alias (such as `size_t` or `ssize_t`), `false` otherwise * MetaProcessor - Implemented `isTypeAlias(string)` which determines if the given type is a type alias. - Implemented `getConcreteType(string typeAlias)` which transforms the type alias into its concrete type; this method incorporates defensive programming in that it will only apply the transformation IF the provided type alias is infact a type alias, otherwise it performs an identity transformation and returns the "alias" untouched. * TypeChecker - Clean up * MetaProcessor - `doTypeAlias(Container, Statement)` now makes use of `isTypeAlias(string)` and `getConcreteType(string)` * - `typeRewrite(MTypeRewritable)` now makes use of `isTypeAlias(string)` and `getConcreteType(string)` * MetaProcessor -

Removed reference to `SymbolType.REPR` in checker * Parser - Removed reference to `SymbolType.REPR` and `Repr` which was used for testing the `MetaProcessor` in early stages * 🧹️🧼️ Cleanup: Clean up series 1 (#16) * ⚡️ Feature: Lexer Interface cleanup (#14) * LexerInterface Defined the lexer interface * Parser - Fixed import for `Token` class - Removed the token management fields such as `tokens`, `currentToken` and `tokenPtr` as these are now replaced by our `LexerInterface`, `lexer` field which manages this all for us - Removed constructor which accepts a `Token[]`, now onyl accept a `LexerInterface` - Removed `nextToken()`, `hasTokens()`, `getCurrentToken()`, `previousToken()`, `setCursor(ulong)` and `getCursor()`. - The above now are called via the `lexer` instance Parser (unit tests) - Migrated to new `LexerInterface`+`BasicLexer` system - Hoisted out common imports for unit tests into a `version(unittest)` TypeChecker (unittests) -

Fixed imports for the (now) `BasicLexer` - Fixed imports for the (now) `lexer.core` package Compiler - Fixed imports for the (now) `BasicLexer` - Use `LexerInterface` instead of `Lexer` - The `doLex()` method now uses an instance of `BasicLexer` and then downcasts to quickly call `performLex()` in order to tokenize and make them available - The `doParse()` method now takes in an instance of `LexerInterface` rather than `Token[]` BasicLexer (previously Lexer) - Moved to the `lexer.kinds` package - Now implements `LexerInterface` - Documented module and class - Documented the `LexerInterface` methods Exceptions - Moved to the `lexer.core` package - Fixed import of `Token` class - Now uses `LexerInterface` Core.Lexer.Package - Documented package module Tokens -

Documented module * Typing (core) - Documented module - Documented all members * Exceptions (lexer) - Fixed documentation missing parameters * Check - Make comments docs/ddox compatible * BasicLexer - Fixed parameter name in documentation * BasixLexer - Fixed formatting in documentation for class * Typing (core) - Documented all remaining class members and fields * - Update `.gitignore` * Commands - Handle `Exception` as well, I know DGen emits this on CC error so we should DO this to make tests more accurate * Commands - Fixed variable usage * Instructions - Made `BinOpInstr`'s left-hand side instruction of type `Value` and right-hand side instruction of type `Value` too - Doesn't make sense to use anything but `Value`-based instructions for it * Containers - Removed redundant import that causes compilation failure on `ldc2` * 🐞️ Functions: Expressionless return and enforcing requirement (#7) * Parser - Added a TODO in `parseReturn()` for issue #113 * Data - The `ReturnStmt` now has a default constructor which is for cases where one doesn't want to provide an expression (for expressionless returns) Parser - `parseReturn()` now supports expressionless returns Test cases - Added `simple_return_expressionless.t` to test expressionless return statement * Data - Added a method `hasReturnExpression()` to `ReturnStmt` which returns `true` if the return statement has an expression attached, `false` otherwise * Dependency - When processing a `ReturnStmt` only run do dependency generation for the return statement's expression IF it has one * Instruction - Made `ReturnInstruction` have a constructor which takes in no `Value` instruction (intended for return expression) - Added a `hasReturnExpInstr()` to `ReturnInstruction`such that during typechecking/codegen we can check for it * TypeChecker - Added a TODO regarding the missing typechecking for `ReturnStmt` typechecking. Added notes on how we'd go about this. - Fixed crash due to assuming there was always an expression on the stack that could be popped off for generating a `ReturnInstruction` (this is not the case when the return statement is expressionless) * Tests - Added a typecheck test for `simple_return_expressionless.t` * TypeChecker - Update `isSameType(Type t1, Type t2)` to check if the actual types of both `Type` objects are the same as a last resort - Added a `NOTE` comment on how `isSameType(Type t1, Type t2)` is implemented - Added typechecking code for `ReturnStmt` and updated the code generation with it. We now do the following: 1. We extract the container of the `ReturnStmt` and cast it to a `Function`; if it is not a `Function` we throw an error because you cannot have a `ReturnStmt` appear in a non-`Function` container 2. We extract the function's name relative to it container (the function's container) for use of it in error messages 3. Next, we get the return type of the function and do the following: a. If the return type is `void` i. If the return has an expression we throw an error ii. If the return has NO expression we pass typechecking and generate the `ReturnInstr` b. If the return type is non-`void` i. If the return has an expression we ensure that its type matches that of the function's return type and generate the `ReturnInstr` ii. If the return has NO expression we raise an exception as one is expected 4. If we pass and got here then we set the `ReturnInstr`'s context and `addInstrB(returnInstr)` * Test cases - Added test case `simple_return_type.t` which is here to test our return type checking * - Updated `.gitignore` * Parser - Use `lexer` for all `Token`-based operations * Resolution - Implemented `findContainerOfType(TypeInfo_Class, Statement)` which, given a type-of `Container` and a starting `Statement` (AST node) this will swim upwards to try and find the first matching parent of which is of the given type (exactly, not kind-of). * TypeChecker - Fixed the `Function` `Container` resolution for the `ReturnStmt` to now find the nearest `parent` in its parenthood tree which is a `Function`, extract the `Function`'s name and then use that where needed * 🐞 Bugfix: Ensure that typed functions contain a return statement (#17) * Parser - Added TODO for checking for non-`void` function's return statements * Parser - If a `ReturnStmt` is not found after calling `parseFuncDef()` * Parser - Added a FIXME comment that needs to be completed soon * Parser - Only check that a `ReturnStmt` is present in a function definition when `wantsBody` is true ELSE we'd expect it for `efunc` `extern`'d statements - Fixed a unit test which had a missing `return <expr>` - Added a unit test which tests for a function definition with a body with a non-void return type that it DOES fail - Removed two now-completed TODOs and FIXMEs Test cases - Fixed test case in `typecheck/simple_function_call.t` to now include the required `return <expr>` statements * 🐞 Bugfix: Recursively check for return statemen tprescence (#19) * Parsing - Added a TODO for where the fix needs to be * Parser - Implemented `findOfType(TypeInfo_Class statementType, Container from)` which given a type of `Statement` to look for and a `Container` of which to search with in. This method will recursively search down the given container and look for any statements which are a kind-of (`isBaseOf`) the requested type. it will return an array of `Statement` (`Statement[]`) of the matches. - Implemented `existsWithin(TypeInfo_Class statementType, Container from)` given a type of `Statement` to look for and a `Container` of which to search with in. This method will recursively search down the given container and look for any statements which are a kind-of (`isBaseOf`) the requested type. It will return `true` if any matches are found. - We now will recursively explore the `Function`'s body statements in search of a `ReturnStmt` * Parser (unit tests) - Updated unit test which was meant to check for a greater number of body statements of the `Function` at question * Parser (unit tests) - Because this causes `expect(string)` to be called (this unit test) we must catch `TError` as that is what `expect(string)` throws - We should update this (see https://deavmi.assigned.network/git/tlang/tlang/issues/147) * Tets cases - Added missing `return` to function `banana` in `simple_functions.t` test case * Test cases - Fixed `simple_function_decls.t` to include the required (but missing) `return` statement * 🐞 Bugfix: expect(string) should throw ParserException atleast (#20) * Parser - Removed commented-out code * Parser - Removed `isUnitTest` variable and how `expect(string)` relies on it * Parser - Now throw a new `ParserException` instead of a `TError` when calling `expect(string)` * Parser - Made `expect(string)` not static * TypeChecker - Implemented `expect(string)` which throws a `TypeCheckerException` in a similar fashion to `Parser`'s `expect(string)` * Dependency - Implemented `expect(string)` which throws a `DependencyException` in a similar fashion to `Parser`'s `expect(string)` Exceptions (dependency) - Added enum member `GENERAL_ERROR` to `DependencyError` * Parser (unit tests) - Made more specific * Parser - Removed now-completed TODO * Data - Removed unused type `ArgumentList` * Expressions - Made the `Expression` class abstract - Removed irrelevant TODOs and method - Removed uneeded constructor VariableExpression - Removed unused junk * 🧠 Feature/Meta: Cloneable (round 1) (#21) * Data - Moved AST manipulation imports to the top - Made `VariableAssignment` cloneable - Made `Variable` cloneable * Data - When trying to `clone()` an `Expression`, do a runtime type check to check if we can (else `null` is used) * Expressions - Moved AST-manipulation related import to the top * Expressions - `BinaryOperatorExpression` now overrides `clone()` from `MCloneable` * Expressions - `IntegerLiteral` now implements `MCloneable` * Expressions - `CastedExpression` now implements `clone()` for `MCloneable` * Containers - Moved all AST maniuplation-related imports to the top * Containers - Made `Struct` support `MCloneable`'s `clone()` method * Data - Only clone the `VariableAssignment` if the `Variable` has one * Containers (unit test) - Added test which tests the `clone()` on a `Struct` * DGen - If `typeTransform(Type)` fails then the debug text should be in the error coloring * DGen - If `typeTransform(Type)` is called on an unknown type then print out the type in the error message asx well * Mcro - Made `MCloneable`'s `clone()` require a `Container` argument of which the final cloned `Statement` must parent-itself to * Expressions - `BinaryOperatorExpression`, `CastedExpression` and `IntegerLiteral` now implements the new `MCloneable` API * Expressions - Added notes about where parenting must manually be done * Data - `Variable` and `VariableAssignment` now uses the new `MCloneable` API * Containers - `Struct`'s `MCloenable` API adhered to * Containers - Fixed `clone(Container)` implementation for `Struct` whereby it would not parent the newly created copy * TypeChecker - Added a TODO regarding the `ClassStaticNode` handling * TypeCheck - Undo incorrect FIXME * CodeEmitter - Added a new parameter to `transform(Instruction)` (now `transform(Instruction, Object)`. `customRules` is an `Object` to be interpreted by the underlying emitter which can change how certain transformations are done when it is in a certain state DGen - Uses new `CodeEmitter` API * Revert "CodeEmitter" This reverts commit 75372ee13252737304dde5473384b6e47d30b056. * DGen - Added ability to flag whether symbol mapping should occur or not - By default enable symbol mapping * Variable - When calling `replace(Statement, Statement)`, if we hit the `variableAssignment` replacement check, first check and ensure it is not null`, try * 🧠️ Feature: Universal coercion and type enforcer (#9) * TypeChecker - Added `bool isSameType2(Value v1, Value v2, bool attemptCoercion = false)` for future implementation of universal coercion as per #115 * TypeChecker - Renamed `isSameType2` to `typeEnforce` - Updated `typeEnforce`'s default parameter documentation from `false` to `attemptCoercion` (as it should have been in the beginning) * TypeCheckerException - Save the `TypecheckError` coming in as `errType` and make it available via `getError()` TypemMismatchException - Save the original (expected) and attempted types and make them available via `getExpectedType()` and `getATtemptedType()` respectively * TypeChecker - Updated `typeEnforce` from taking in `Value v1, Value v2, bool` to `Type t1, Value v2, bool`. - `typeEnforce()` will now extract the `Type` of `Value v2` and call `isSameType(t1, t2)`, if that fails and coercion is allowed then it is attempted, however if that fails then it causes an exception to be thrown. In the case coercion is not allowed, then a `TypeMismatchException` is thrown Unit tests - Tested the new `typeEnforce(Type t1, Value v2, bool)` and it seems to work, both a case of failing matching (coercion disallowed) and working coercion (coercion allowed) * TypeChecker - Documented existing unittest for `typeEnforce(Type, Value, bool)` - Added new unit test for `typeEnforce(Type, Value, bool)` which tests when the types ARE the same * TypeChecker - Cleaned up `typeEnforce(Type, Value, bool)` * TypeChecker - Added a work-in-progress unit test to test how I would use `typeEnforce(Type t1, Value v2, bool coercion = false)` in practice - Added TODOs in `attemptCoercion(Type, Type)` where I must add support * TypeChecker - Finished the unit test testing out the usage for `typeEnforce(Type, Value, bool coerce = false)` - Added TODOs to `attemptCoercion(Type, Value)` for the changes required to it * TypeChecker - Removed incorrect TODOs from `attemptCoerce(Type, Value)` and updated the message when the coercion fails Unit tests - Updated first unit test for `typeEnforce()` to test failing coercion on a non-`LiteralValue` instruction - Added a unit test where `typeEnforce()` WILL pass as it coerces a `LiteralValue` instruction * Exceptions (`typechecker`) - Added new exception type `CoercionException` to be thrown whenever a coercion cannot take place. * TypeChecker - Ensure that `attemptCoercion(Type, Value)` only throws instances of `CoercionException` * Unit tests - Fixed failing-coercion check by catching the correct exception when it fails `CoercionException` instead of `TypeMismatchException`) * TypeChecker - Added documentation for `isSameType(Type t1, Type t2)` * TypeChecker - Updated documentation for `isCoercibleRange(Type, Value)` - Updated `attemptCoercion(Type, Value)` with new documentation and renamed parameters * Unit tests (typechecker) - Added comments * TypeChecker - Removed now-completed TODO in `typeEnforce(Type t1, Value v2, bool allowCoercion = false)` * TypeChecker - Removed unused `typeStatus` variable in `typeEnforce(Type, Value, bool)` * TypeChecker - Variable declarations (with assignments) now use the `typeEnforce()` method with coercion allowed in order to do the type checking and coercion changes - Added a comment explaining a certain branch of `attemptCoercion(Type, Value)` * TypeChecker - If the to-type and provided-type are both numerical then use a size-based test Test cases - Added two test cases which test `typeEnforce()` on incoming `Value`-based instructions as part of variable declarations * Test cases - Fixed negative test case - it MUST have an error and that should be seen as a pass * TypeChecker (unit tests) - Disabled invalid unit test (marked for re-writing) - I should re-write the below. It is now incorrect as I DO ALLOW coercion of non literal-based instructions now - so it fails because it is using an older specification of TLang * TypeChecker - Migrated the type checking of standalone variable assignments to using `typeEnforce()` Test cases - Added positive and negative test cases * - Updated `.gitignore` * Feature/type enforcer cast instr emit (#13) * TypeChecker - `typeEnforce()` now will not change the type of `Value`-based instruction `v2` but rather return, on successful coercion set a `ref`-based argument to a new instance of a `CastedValueInstruction`, if coercion fails or was disabled and types mismatched then an exeption is thrown as normal. - If the types are an exact same match, a-la `isSameType(Type, Type)`, then this `ref` value is set to `v2` (makes programming easy) else we would have no way to know - `attemptCoerce()` now, to go with the above changes to `typeEnforce()`, returns a `CatsedValueInstruction` to the to-type on successful coercion, else an exception is thrown as usual - Updated two cases of `typeEnforce()` usage to the new method signature, also now add a sanity check assertion that the types now DO match as they should * TypeChecker - We need not set it again, look the value we use when we CALL `typeEnforce()` is that of the `fromInstruction` and if no changes occur we still have it, it is fine - if it changes via the call to `typeEnforce()` via the `ref` based argument thne same old - No need for us to set it here in the event of no changes, we are writing back the exact same Instruction/object-reference * TypeChecker (unit tests) - Upgraded to the new `typeEnforcer()` method signature * TypeChecker - Improved documentation for `typeEnforce()` * TypeChecker - Added TODO regarding pointer coercion with integers in `Pointer + Integer` case (for pointer airthmetic) * TypeChecker - Added a new branch which currently throws an exception as it is unimplememted - This branch (above) is in `attemptCoercion()` and is to handle the coercion of `Integer` to `Pointer` for pointer arithmetic - When doing the typechecking/codegen for `BinaryOp`, disable the pointer coercion call to `attemptPointerAriehmeticCoercion()`, instead now make calls in those cases they apply, to `typeEnforce()` - The above stuff is still broken, not yet implemented. * TypeChecker - Cannot use cast as that can return false positives for an all pointer case as all `Pointer`s are `Integer`s - Added `isPointerType(Type)` to check the above - Added then also `isIntegralTypeButNotPointer(Type)` which checks for an `Integer` type but excluding if it is a `Pointer` - Updated the checks in the `BinaryOperator` branch of `typeCheckThing(DNode)` to do this * TypeChecker - Need to do the `Pointer` checks first in `attemptCoercion(Type, Value)` * TypeChecker - `attemptCoercion(Type, Value)` now returns a `CastedValueInstruction` to cast the `Integer` type to the `Pointer` type * TypeCHecker - Catch mis use of type enforcement by using `isIntegralTypeButNotPointer(Type)` and isPointerType`(Type)` for the previous commit * TypeChecker - Refresh the types after the potential calls to `typeEnforce(..., ..., ..., ...)` * Pipeline - Use `set -e` for `simple_pointer.t` test in emit stage * Pipelines (emit stage) - Previous compilation may have succeeded, meaning ./tlang.out never gets updated and exits fine with 0, but we only use the last commands exit status to check for a pass for a test. - By setting this if COMPILATION fails then we exit with its code and the test status is set via that * Pipelines - Removed the `set -e` code as the correct `Exception` now causes a non-zero exit code from the changes made in `varass_vardec_dependency` * DGen - Added notice for issue #140 * TypeChecker - Made `isIntegralTypeButNotPointer(Type)` public - Made `isPointerType(Type)` public * Instructions - `CastedValueInstruction` now is unrelaxed by default but can be set (tis aids in how it can be emitted later for issue #140) * DGen - Added some checks for certain conditions whereby pointer coercion requires relaxing the casted operands (coerced operands) * DGen - Relax `CastedValueInstruction`(s) when appropriate in `BinaryOpInstr` handling code - Removed panics * DGen - Added relaxation support to the code emitting code for `CastedValueInstruction` * DGen - make debug messages for when relaxation occurs for `CastedValueInstruction` emitting more clear * TypeChecker - Implemented `biggerOfTheTwo(Integer, Integer)` which determines the biggest of the two `Integer`-based types and returns that one. * TypeChecker - Fixed incorrect variable name in `biggerOfTheTwo(Integer, Integer)` * TypeChecker - Throw an error in the case where a `BinaryOperatorExpression` occurs with non-`Integer`-based instructions (at least for now) * TypeChecker - If both types are `Integral` (but not `Pointer`) then smaller coerces to bigger, if they however are equal then signed coerces to unsigned * TypeChecker - Removed now irrelevant comment * TypeChecker - Don't throw exception here, rather let the `isSameType(Type, Type)` check handle that - We still keep the warning we print about missing cases implementation-wise * TypeChecker - Fixed explanation * TypeChecker - Marked related issue * TypeChecker - Implemented ` isStackArrayType(Type typeIn)` - WIP: Added a check for handling `StackArray -> Pointer` coercion to `attemptCoercion(Type, Value)` * TypeChecker - `attemptCoercion(Type, Value)` will now ensure firstly that the `StackArray`'s component type matches that of the `Pointer`'s referred type, if not throw an exception, if so, then return a `CastedValueInstruction` * TypeChecker - Print out a debug message when attempting to coerce a `StackArray` to a `Pointer` - Fixed the error message thrown when a `StackArray` could not be coerced to a `Pointer` due to the component type != ptr's referred type - `FunctionCall` handling now has the `canCoerceStackArray()` code disabled and uses the `typeEnforce()` method * TypeChecker - Type checking code for `FunctionCall` * TypeCheck - Completed TODO comment * TypeChecker - Added a TODO * TypeChecker - Added FIXME where the `typeEnforce()` call need to be made for the `ReturnStmt`'s return expression's type to match or be checked-against the containing `Function`'s * TypeChecker - `ReturnStmt` now uses `typeEnforce()` * Test cases - Added two new checks for checking the return type of a function and matching a `ReturnStmt`'s expression's type to it * TypeChecker - Removed assertion check, rather let the exception thrown handle the error - Only after we know the finally-parenting `Container` is a `Function` (should we reference `funcContainer` * Test cases - Removed explicit cast from `simple_function_recursion_factorial.t` * TypeChecker - If we have a `LiteralValue` and a non-`LiteralValue` then coerce the `LiteralValue` towards the non`-LiteralValue` via `typeEnforce()` - This should allow the correct range checking of literal values within the range of the to-type and not require annoying explicit casts * Test cases - Removed now-unneeded explicit casts on literal values in `simple_function_recursion_factorial.t` * TypeChecker - Added comment describing the process used - Removed now-completed TODO * TypeChecker - Removed some dead code - Removed now-completed FIXME/TODO * TypeChecker - Removed old type checking code for variable declarations with assignments - Removed old type checking code for standalone variable assignments * Dub - Upgraded `jcli` to version `0.25.0-beta.2` * Dub - Upgtraded package `jcli` to version `0.25.0-beta.3` * - Try using latest version of `dmd`
