| 2022-02-07 | source: convert source objects into proper uc_value_t type | Jo-Philipp Wich | |
| Instead of implementing a custom limited refcount logic, turn uc_source_t instances into proper uc_value_t objects. Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-02-07 | treewide: rework function memory model | Jo-Philipp Wich | |
| - Instead of treating individual program functions as managed ucode types, demote uc_function_t values to pointers into a uc_program_t entity - Promote uc_program_t to a managed type - Let uc_closure_t claim references to the owning program of the enclosed uc_function_t - Redefine public APIs uc_compile() and uc_vm_execute() APIs to return and expect an uc_program_t object respectively - Remove vallist indirection for function loading and let the compiler emit the function id directly when producing function construction code Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-29 | program: rename bytecode load/write functions, track path of executed file | Jo-Philipp Wich | |
| Extend source objects with a `runpath` field which contains the original path of the source being executed by the VM. When instantiating source objects from file paths, the `runpath` will be set to the `filename`. When instantiating source buffers using `uc_source_new_buffer()`, the runpath is initially unset. A new function `uc_source_runpath_set()` can be used to adjust the runtime path being associated with a source object. Extend bytecode loading logic to set the source buffer runtime path to the precompiled bytecode file path being loaded and executed. This is required for `sourcepath()` and relative paths in `include()` to function correctly when executing precompiled programs. Finally rename `uc_program_from_file()` and `uc_program_to_file()` to `uc_program_load()` and `uc_program_write()` respectively since the load part now operates on an `uc_source_t` input buffer instead of a plain `FILE *` handle. Adjust users of these API functions accordingly. Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-18 | program: implement support for precompiling source files | Jo-Philipp Wich | |
| - Introduce new command line flags `-o` and `-O` to write compiled program code into the specified output file - Add support for transparently executing precompiled files, the lexical analyzing and com,pilation phase is skipped in this case Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-18 | source: refactor source file handling | Jo-Philipp Wich | |
| - Move source object pointer into program entity which is referenced by each function - Move lineinfo related routines into source.c and use them from lexer.c since lineinfo encoding does not belong into the lexical analyzer. - Implement initial infrastructure for detecting source file type, this is required later to differentiate between plaintext and precompiled bytecode files Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-18 | compiler, vm: use a program wide constant list | Jo-Philipp Wich | |
| Instead of storing constant values per function, maintain a global program wide list for all constant values within the current compilation unit. Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-18 | types: add initial infrastructure for function serialization | Jo-Philipp Wich | |
| - Introduce a new "program" entity which holds the list of functions created during compilation - Instead of storing pointers to the in-memory function representation in the constant list, store the index of the function within the program's function list - When loading functions from the constant list, retrieve the function by index from the program entity Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-04 | vallist: store double values in a platform neutral manner | Jo-Philipp Wich | |
| Import the binary64 double packing routines from the struct module and use them to store numeric double values in a platform agnostic big endian format. Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2022-01-04 | treewide: rework numeric value handling | Jo-Philipp Wich | |
| - Parse integer literals as unsigned numeric values in order to be able to represent the entire unsigned 64bit value range - Stop parsing minus-prefixed integer literals as negative numbers but treat them as separate minus operator followed by a positive integer instead - Only store unsigned numeric constants in bytecode - Rework numeric comparison logic to be able to handle full 64bit unsigned integers - If possible, yield unsigned 64 bit results for additions - Simplify numeric value conversion API - Compile code with -fwrapv for defined signed overflow semantics Signed-off-by: Jo-Philipp Wich <jo@mein.io> | |||
| 2021-12-08 | vm: introduce value registry | Jo-Philipp Wich | |
| Introduce a new, lazily allocated value registry which can be used by C code to store values which should not be garbage collected. The registry is a plain ucode object internally and treated as GC root but not exposed to ucode script code, this allows it to retain references to values which are otherwise completely unreachable from ucode scripts.

| 2021-10-11 | syntax: introduce optional chaining operators | Jo-Philipp Wich | |
| Introduce new operators `?.`, `?.[…]` and `?.(…)` to simplify looking up deeply nested property chain in a secure manner. The `?.` operator behaves like the `.` property access operator but yields `null` if the left hand side is `null` or not an object. Like `?.`, the `?.[…]` operator behaves like the `[…]` computed property access but yields `null` if the left hand side is `null` or neither an object or array. Finally the `?.(…)` operator behaves like the function call operator `(…)` but yields `null` if the left hand side is `null` or not a callable function.
