ucode - The ucode Scripting Language

Age	Commit message (Collapse)	Author
2021-07-11	treewide: move header files into dedicated directory	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-07-11	treewide: consolidate typedef naming	Jo-Philipp Wich
	Ensure that all custom typedef and vector declaration type names end with a "_t" suffix. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-07-11	vm: make root exception handler configurable	Jo-Philipp Wich
	So far, the VM simply printed exception information to stderr if the exception was not catched in managed code. Host programs embedding ucode might want to customize that behaviour, so refactor the current defualt behaviour into a callback function and add a public getter and setter to allow changing the exception handler callback.

2021-07-11	lib, vm: reimplement exit() as exception type	Jo-Philipp Wich
	Instead of invoking exit(3) from uc_exit(), use a new EXCEPTION_EXIT exception type to instruct the VM to shutdown cleanly. This is required to not terminate the host program in case libucode is embedded and loaded scripts invoke the exit() function. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-07-11	treewide: move ressource type registry into vm instance	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-05-25	lexer: implement raw code mode	Jo-Philipp Wich
	Enabling raw code mode allows writing ucode scripts without any template tag decorations (that is, without the need to provide an initial opening '{%' tag). Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-05-10	vm: implement mechanism to change output file descriptor	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-05-07	vm: truncate long values after 60 chars in trace output	Jo-Philipp Wich
	Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-05-04	syntax: implement support for 'use strict' pragma	Jo-Philipp Wich
	Support per-file and per-function `"use strict";` statement to opt into strict variable handling from ucode source code. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-05-04	lib: add support for pretty printing JSON to printf() and sprintf()	Jo-Philipp Wich
	Honour precision specifiers when parsing `J` format strings to enable or disable JSON pretty printing. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-04-27	treewide: ISO C / pedantic compliance	Jo-Philipp Wich
	- Shuffle typedefs to avoid need for non-compliant forward declarations - Fix non-compliant empty struct initializers - Remove use of braced expressions - Remove use of anonymous unions - Avoid `void *` pointer arithmetic - Fix several warnings reported by gcc -pedantic mode and clang 11 compilation Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2021-04-25	treewide: rework internal data type system	Jo-Philipp Wich
	Instead of relying on json_object values internally, use custom types to represent the different ucode value types which brings a number of advantages compared to the previous approach: - Due to the use of tagged pointers, small integer, string and bool values can be stored directly in the pointer addresses, vastly reducing required heap memory - Ability to create circular data structures such as `let o; o = { test: o };` - Ability to register custom `tostring()` function through prototypes - Initial mark/sweep GC implementation to tear down circular object graphs on VM deinit The change also paves the way for possible future extensions such as constant variables and meta methods for custom ressource types.
