* - declare-macro has returned.Eduardo Julian2015-05-017-67/+157
| | | | | | - Method-invocation special forms now take the wanted method as an unprefixed symbol, instead of as text. - Some fixes in lux.analyser.host. - Lambda analysis now just returns the origin exo-type instead of the endo-type. - Made some changes to the type of the CompilerState.
* - Implemented pattern-matching for records.Eduardo Julian2015-04-304-44/+111
| | | | - Added some code to allow variant creation with existential types. (NOTE: Check if it's actually valid) - Modify var cleanup to leave the var as-is if it has been deleted. (NOTE: Need to find out why a variable is left prior to being deleted)
* - Improved the way vars are deleted by including code to remove all ↵Eduardo Julian2015-04-301-8/+28
| | | | references to the removed var from other vars.
* - Made a slight correction to the Syntax type when it comes to records ↵Eduardo Julian2015-04-291-17/+33
| | | | | | | (slot-names are no longer Text, but Syntax). - lux/type;bound? no longer does further derefs to check for bound-ness? - Improved the way 2 type-vars are type-checked. - When cleaning type-vars, the dereffed typed is no longer cleaned again.
* - Fixed some errors in lux.lux.Eduardo Julian2015-04-2811-161/+189
| | | | | | | | | | | | - Added the ability to export from def. - Added an optimized lambda macro. - Finished record analysis & compilation. - Fixed a bug in tuple, function & record analysis wherein AppT wasn't being performed prior to analysing the expression under analysis. - Fixed several bugs wherein "fail*" was needed but "fail" was used. - Added a case for records in base;show-ast. - Made an improvement for AllT in type;show-type. - Corrected an error in pattern-matching compilation wherein casts weren't being performed to make sure the source datum was of the necessary type for PM. - Removed the (now unnecessary) lux/macro.
* - Added a new type of definition (#TypeD (,)), to take advantage of an ↵Eduardo Julian2015-04-261-10/+28
| | | | optimization where I can skip doing a full-blowing type-check by doing a pointer-check with &type/Type for both the exo-type and the endo-type.
* - lux/analyser/def has been renamed to lux/analyser/module.Eduardo Julian2015-04-266-239/+275
| | | | | - Renamed a few defs in lux.lux. - No more type-test shortcut inside lux/analyser/lux. - Defs are now being classified as either (#ValueD <type>) or (#MacroD <macro>).
* Made a correction to lux.lux and the analyser regarding how to handle type-vars.Eduardo Julian2015-04-262-5/+13
|
* Made a small change in regards to how global defs are resolved.Eduardo Julian2015-04-263-6/+14
|
* - Macros are no longer declared. Instead, they are automatically detected.Eduardo Julian2015-04-263-16/+95
|
* - No more Any (Top) and Nothing (Bottom) types.Eduardo Julian2015-04-256-294/+282
|
* - More accurate AllT environment management by using (Maybe TypeEnv) instead ↵Eduardo Julian2015-04-251-29/+56
| | | | of TypeEnv. The performance of the type-checker also improved thanks to that.
* - Migrated all the record data-structures to the new tuple-like format.Eduardo Julian2015-04-238-95/+122
|
* - Fused lux;local-envs & lux;global-envs as lux;envs.Eduardo Julian2015-04-235-70/+58
|
* - Added a dummy implementation of "export'".Eduardo Julian2015-04-236-68/+58
| | | | | - Fixed a bug wherein bool pattern-matching was only considered total if there was a wildcard, despite true & false cases where provided. - Changed the syntax of the jvm-interface special form. - Refactored the lux;writer, lux;eval-ctor & lux;loader fields of the CompilerState into a single data-structure which is now stored under the lux;host field
* - Removed analyse-2, as it was redundant.Eduardo Julian2015-04-238-62/+87
| | | | | - Fixed several bugs within lux.lux. - Renamed "check'" to ":'" and "coerce" to ":!".
* - Fixed several bugs in lux.luxEduardo Julian2015-04-1910-273/+307
| | | | | | | - Fixed an error in lux.base/analyse-2 - Modified the analyser so the symbols that identify all of the special forms must mandatorily have "" as their prefix. - Fixed a bug in the binary operations at lux.analyser.host wherein the types where being omitted. - Fixed a bug when closing-over variables inside lambda bodies wherein the names of bindings where being stores as (incomparable) arrays, instead of as (comparable) strings.
* - Solved the bug wherein type-inferencing was causing computational ↵Eduardo Julian2015-04-173-114/+110
| | | | | | | complexity to explode and cause the compiler to become very slow (solved it by removing type-inference from tuples). - Also removed type-inference from functions/lambdas. - Added a small optimization to improve the efficiency of type-checking by not doing a thorough type-check when a global or local binding has a type variant with the same cases as Type, and it's exo-type is also like this (hopefully, it will never happen that someone will exploit this to make the compiler do something weird...)
* - |do bindings are now based on pattern matching (that way, tuple ↵Eduardo Julian2015-04-1610-374/+366
| | | | | | | | destructuring can be done at do). - Patterns are no longer put inside a MatchAC structure, but are instead just moved around as lists. - Code outside of &type can no longer create/delete type-vars directly, but must now rely on with-var & with-vars to manage the life-cycle of type-vars. - Simplified pattern-matching analysis at lux/analyser/case. - The LEFT_APP optimization in check* has been replicated on the other side as RIGHT_APP, to attempt to improve performance of pattern-matching.
* - Type-vars can now be deleted and be scoped (through with-var).Eduardo Julian2015-04-168-332/+474
| | | | | - Fixed a few bugs with types and pattern-matching. - Fixed a bug wherein primitive-analysis did now unify the primitive type with the exotype. - Modified lambda-analysis so functions subject to universal quantification can manage better the universally-quantified variables.
* - Fixed a few type-related bugs.Eduardo Julian2015-04-159-325/+284
| | | | - Variants now need types to be specified both when constructing them as when deconstructing them (in pattern-matching). - Simplified DataT types by no-longer requiring a list of params, so only the tame name is necessary.
* - Function names & parameters now take prefixes into account.Eduardo Julian2015-04-097-63/+155
| | | | | - Added more cases for totality checking in pattern-matching. - Fixed a bug when type-checking function application that used the exo-type for both the function being applied as to the application itself. - Fixed a few minor bugs scattered around that had to do with wrong number of arguments being passed to functions.
* - Renamed exec to |do.Eduardo Julian2015-04-0821-504/+665
| | | | | - :let within |do now uses |let instead of let. - The analyser now does totality analysis and structures the pattern matching, with the compiler only compiling the generated structures. - Local bindings with case' can now be prefixed arbitrarily. (Note: must do the same with functions).
* - Identifiers with just a semi-colon in front now have "lux" as their ↵Eduardo Julian2015-04-026-177/+189
| | | | | | | | | module, instead of the local module. (e.g. ;map, #;Cons, ;All) - The type-checker now takes into account 2 types: an exo-type (imposed by outside forces) and an endo-type (generated through inference) - Fixed a few bugs in the analyser and the type-system. - &type/solve* is now the actual type-checker and &type/solve invokes solve* with an empty fixpoint environment. - The exo-type of Statements is Nothing. - variants, tuples and def' are being analyzed properly now.
* - Beginning to add type-system + type-inferencer.Eduardo Julian2015-03-3011-400/+482
| | | - Removed exec, get@' & set@' special forms, as they are not primitive enough as to be part of the language.
* - Fixed the bug that caused the infinite look while compiling the file.Eduardo Julian2015-03-226-24/+61
|
* - Added code-cursors (file-name, line-number, column-number) as metadata on ↵Eduardo Julian2015-03-2210-297/+359
| | | | lexer nodes & parser nodes.
* - Added the reading-phase and it's associated structure as the mediator ↵Eduardo Julian2015-03-214-306/+394

| | | | - Fixed a bug when compiling lambda instantiation (the bug had to do with compiling the env variables passed to the closure). - Fixed a bug in the lexer wherein the backquote (`) wasn't being recognized.
* - Changed once more the syntax of the prefix for host special forms. It's ↵Eduardo Julian2015-03-0813-571/+260
| | | | | | | | | | now "jvm-" instead of "jvm;" - Fixed the bug where the same local vars/registers were getting registered more than once and the class-verifier complained. - Fixed a bug where the "end label" for pattern-matching bodies was never inserted. - Simplified the analyser by removing "self" calls and having self be just a local for the "this" object (register 0). - Removed the lambda-folding optimization. - The compiler state now holds and environment for naming globally-scoped lambdas.

| | | | of using custom classes for that.
* Code compiles again! (although, I had to employ a hack for "fold", as ↵Eduardo Julian2015-03-0111-110/+272
| | | | | | function self-calls are broken). Also fixed several small bugs, including the one that caused ".apply" to never make progress (always returned a function with count 0). Also fixed an issue with scopes that caused class-names to be generated improperly.
