Self-hosted transpiler

[nikodemus]

Able to compile itself. Efficiency of generated code a non-issue.

• build and execute generated C as part of tests
• selector mangling
• proper main
• integers
• unary messages
• binary messages
• keyword messages
• let
• assignment
• simple blocks
• blocks with arguments
• block closures
• slots & instance constructors & instance variable access
• class
• self
• return
• assignments to slots
• prefix messages
• class references
• Self
• Primitive Booleans
• is
• Block #finally
• floats
• strings
• static allocation for literal strings
• define integer
• define float
• define string
• True & False
• define boolean
• dynamic bindings
• interface definitions
• type annotations: value
• type annotations: method argument
• type annotations: block argument
• interface typechecks
• type annotations: let binding
• generate forward-declarations for builtin vtables (currently hardcoded)
• type annotations: slot
• type annotations: method return value
• type annotations: block return value
• automatic reader methods
• arrays
• extend
• panic
• import lang.any
• import lang.stringOutput
• Class#includes:
• import needs to handle transitive dependencies automatically in transpiler
• import lang.object
• import lang.boolean
• handle transitive relative imports in self-hosted interpreter and transpiler
• required methods
• import lang.iterable
• import lang.interval
• import lang.number
• import lang.integer
• import lang.float
• selector
• import lang.collection
• import lang.ordered
• import lang.array
• backtrace for runtime errors
• clean up #== and #isEquivalent (-> Boolean or not, defined where?)
• implement C3 linearization for interface inheritance
• import lang.string
• TestTranspilerPreludeFloat fails when run without --fork-all - presumably an earlier tests leaves behind something?
• records
• define arrays
• define records & instances
• import lang.character
• import lang.closure
• import lang.exception
• #perform:with:
• import lang.selector
• import lang.record
• import lang.test
• transpiler Main class#run:in: instead of #run.
• import lang.output
• impl FilePath
• impl File
• impl FileStream
• import lang.filepath
• import lang.file
• import lang.filestream
• impl Time
• import lang.time
• import bytearray (fails because making it Ordered breaks something)
• import dictionary. Plan: alist-style implementation for now.
• interpolated strings
• transpiler to handle prelude properly: import into global environment
• import impl.parser
• transpile with whole prelude 🔥
• Class and Interface globals in transpiler (and evaluator)
• interface inheritance in runtime allocated classes
• instantiation of slotless runtime classes
• instantiation of heap-allocated runtime classes
• class inheritance in runtime allocated classes
• transpile evaluator 🔥
• import lang.class
• import lang.interface
• uniquefy mangled global names
• System#command:
• transpile transpiler 🔥
