lexer nodes & parser nodes.
|
|
between raw source-code and the lexing-phase.
|
|
|
|
- System works correctly once more.
|
|
- Corrected more bugs in the system.
|
|
- Changed indents to symbols.
- Corrected some of the bugs in the system. Many more still awaiting fixes.
|
|
- Finished moving the codebase to use the functions from lux.base with the "&" prefix.
|
|
- Migrated more of the compiler's data-structures to using Lux's format.
|
|
- Compiler-state is now using Lux record-format.
- Went from Error+Ok to Left+Right.
|
|
- Finishing implementing the type-system.
- Migrating more of the data-structures used in the compiler to the ones used by Lux itself.
|
|
- Added invokespecial & invokeinterface.
- Added putstatic & putfield.
- Corrected primitive conversions & bitwise operators to take into account (un)boxing.
|
|
- Added bitwise operators.
- Added synchronization primitives (monitor enter & exit).
- Added exception-handling.
- Added conversions between primitive values.
|
|
|
|
format as lux data-structures, to ease communication between the compiler & macros.
|
|
- Made a small change in float & double comparisons to make sure NaN < n.
|
|
- The lexer now allows "-" in front of numbers to get negative numbers.
|
|
|
|
- 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.
|
|
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.
|
|
- Added a list of optimizations to do in the future (after the language is functionally complete).
|
|
of using custom classes for that.
|
|
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.
|
|
- For some reason, when I fail at compilation due to mistaken use of tags/variants, I don't get the right error reported.
[Fixes]
- Solved a problem where stack values weren't being properly cleaned-up when pattern-matching on variants and branch bodies.
|
|
- Simplified the code for handling definitions and macros.
- Slightly changed the names of the fields of tuple classes.
- Added a (currently empty) optimization phase.
|
|
Codebase still needs to be simplified further, though.
Also, an explicit optimization phase, between analysis and compilation, must be established.
|
|
- Split lux/analyser/env into "env" & "def" modules.
- Renamed lux/analyser/util to "base".
|

|
## "compiler" subsystem now (almost) compiles.
|
|
## Reorganized a lot of analyser code and got the analyser to compile.
|
|
|
|
|
|
## Good-bye let-expressions...
|
|
|
|
|
|
- The monadic implementation of macros is almost done.
- Missing error-handling.
[Fixes]
- The output folder is now generated on each compiler run to avoid exceptions thrown by the class-loader.
|
|
- Fixed the errors in the compiler due to its restructuring as monadic code.
- Fixed a bug in the analyser where 'case' forms has "Nothing" as their type.
[Refactor]
- Now there only one way to raise/fold lambda-bodies.
|
|
- The analyser trying to match function calls first was messing around with variant construction.
[Working on]
- Monadic macros.
|
|
- The compiler is now working properly post-refactoring.
- The code for generating lambdas was refactored, though it needs to be broken-down further.
|
|
- Huge refactoring of the lux/compiler ns.
- No more difference between compiling global lambda definitions vs regular lambdas.
|
|
- 'def' with 'lambda' as value now experiences a rewrite to eliminate the localized lambda-name and use the name of the global-def for the sake of making it easier to understand to users/programmers.
|
|
- Improved the way raise-bindings works.
|
|
- Almost finished rebuilding lambda syntax so it always has local names and only takes 1 argument.
|
|
[Enhancements]
- Restructured the lexer a bit.
- Restructured the parser a lot.
- Changed the syntax a bit.
- Module-names are now separated from def-names by a colon (e.g. module/submodule:var)
- i+ -> iadd, i- -> isub, i* -> imul, i/ -> idiv
- Added a (incomplete) way to annotate defs. Currently, only serves to mark defs as macros.
- Removed "import" and "use". "require" is meant to be the way to load modules.
- Did some major refactoring, cleaning and upgrading in the analyser. Though there is still some work pending.
|
|
- Simplified lexer.
- Parser now does cleanup of comments & white-space, plus balancing of parens/brackets/braces and checking for even number of elements in records.
- Lexer & parser now share state.
|
|
- Removed a lot of useless comments & logging.
- Removed the useless test1.lux file.
|
|
- Removed the issue that was causing the compiler to never display the true source of errors.
[Enhancements]
- Separated the prelude (lux.lux) and utils (util.lux) from the code at test2.lux
- The compiler now handles module-separation a bit better
[Cleanup]
- Removed the unnecessary another.lux
[Temporary]
- The base classes/interfaces are now assumed to be in the "lux" module, but they must be moved to "lux/host"
|
|
Source code is looked-up inside a "source" directory.
|
|
.class files are now stored inside an "output" directory.
|
|
- In let forms, the local had the wrong data-structure as a type.
[Enhancements]
- Can now instance objects.
- Java-interop now handles array inputs.
- System now has object array creation, storing and retrieving.
