Andreas Kling	98f2da9834	LibJS: Rename Cell::visit_children() => Cell::visit_edges() ... The GC heap is really a graph of cells, so "children" didn't quite feel appropriate here.	2020-11-28 17:16:48 +01:00
Andreas Kling	6861c619c6	LibJS: Move most of Interpreter into VM ... This patch moves the exception state, call stack and scope stack from Interpreter to VM. I'm doing this to help myself discover what the split between Interpreter and VM should be, by shuffling things around and seeing what falls where. With these changes, we no longer have a persistent lexical environment for the current global object on the Interpreter's call stack. Instead, we push/pop that environment on Interpreter::run() enter/exit. Since it should only be used to find the global "this", and not for variable storage (that goes directly into the global object instead!), I had to insert some short-circuiting when walking the environment parent chain during variable lookup. Note that this is a "stepping stone" commit, not a final design.	2020-09-27 20:26:58 +02:00
Linus Groh	4f6912c605	LibJS: Store basic traceback in Exception ... Nothing fancy like line numbers, but Exception now stores a list of function names up to the current call frame.	2020-06-02 15:22:34 +02:00
Emanuele Torre	937d0be762	Meta: Add a script check the presence of "#pragma once" in header files ... .. and make travis run it. I renamed check-license-headers.sh to check-style.sh and expanded it so that it now also checks for the presence of "#pragma once" in .h files. It also checks the presence of a (single) blank line above and below the "#pragma once" line. I also added "#pragma once" to all the files that need it: even the ones we are not check. I also added/removed blank lines in order to make the script not fail. I also ran clang-format on the files I modified.	2020-05-29 07:59:45 +02:00
Andreas Kling	faddf3a1db	LibJS: Implement "throw" ... You can now throw an expression to the nearest catcher! :^) To support throwing arbitrary values, I added an Exception class that sits as a wrapper around whatever is thrown. In the future it will be a logical place to store a call stack.	2020-03-24 22:21:58 +01:00
