2022-10-25	ucode-mod-lua: improve error reporting	Jo-Philipp Wich
	Avoid redundancies in generated exception messages and include Lua tracebacks when catching exceptions in protected calls. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2022-08-30	ucode-mod-lua: various fixes	Jo-Philipp Wich
	Properly handle accesses to properties of the userdatum itself in the lua_uv_index() __index metamethod and treat integer keys as array indexes in case of wrapped ucode array values. Also fix an incorrect refcount decrement in the function. Also fix uc_lua_vm_get() and uc_lua_lv_getraw() to gracefully handle accesses to not defined or non-table values and ensure that those functions properly reset the Lua stack after they complete.

2022-08-26	ucode-mod-lua: support prototype lookups and method calls on ucode values	Jo-Philipp Wich
	Expose ucode arrays and objects with prototypes as userdata proxy objects to Lua and extend the userdata metadatable with an __index metamethod to lookup not found properties in the ucode values prototype chain. Also extend the __call metamethod implementation to infer method call status from the activation record in order to invoke ucode functions with the correct `this` context when called as method from Lua.

2022-07-27	ucode-mod-lua: add workaround for dynamic Lua extension loading	Jo-Philipp Wich
	Reopen self with dlopen(RTLD_GLOBAL) in order to export liblua symbols for runtime loading of dynamic Lua extensions. Reported-by: Stijn Tintel <stijn@linux-ipv6.be> Tested-by: Stijn Tintel <stijn@linux-ipv6.be> Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2022-05-30	contrib: introduce ucode-mod-lua	Jo-Philipp Wich
	The ucode-mod-lua library provides an ucode-to-Lua bridge and a set of functions to instantiate Lua VMs, invoke Lua functions as well as exchanging data structures between ucode and Lua. Example usage: #!/usr/bin/ucode 'use strict'; const lua = require("lua"); let vm = lua.create(); vm.set({ hello: function(...args) { print(`A ucode "Hello world" function called from Lua! Got arguments: ${args}\n`); }, data_from_ucode: { bool: true, float: 1.3, int: 0x11223344, string: "Hello from ucode!", array: [ 1, 2, 3, null, 5 ], object: { apple: "green", banana: "yellow", [5]: "foo", [-1]: null, nested: { a: [ 5, 6 ], b: { c: NaN } } }, regexp: /foo/ } }); vm.invoke("hello", true, 123, "Foo"); vm.eval('print("Print from Lua!", data_from_ucode.int * data_from_ucode.float);'); try { vm.invoke("error", "Throwing a Lua exception..."); } catch (e) { print(`Caught exception: ${e}\n`); } print(`Lua VM version is: ${vm.get('_G', '_VERSION').value()}\n`); Signed-off-by: Jo-Philipp Wich <jo@mein.io>
