This adds a "timer" module to the CLI that provides a Timer class with
a static sleep() method. Not the most exciting functionality in the
world, but it requires the full hunk of libuv integration:
- The CLI sets up libuv and runs the event loop.
- Added a new directory src/module for CLI modules.
- Updated all the make scripts to handle it.
- Reorganized some other CLI code.
- Add a script that downloads and compiles libuv.
- Hook that up to the Makefile so it pulls down libuv on build.
- Add a separate "vm" target that just builds the VM library and skips
libuv.
- Link to libuv when compiling the CLI.
- Update the XCode project to link to libuv too.
Linux and Windows support isn't done yet, but it should be pretty
straightforward to add to the Python script.
* Eliminate "new" reserved word.
* Allow "this" before a method definition to define a constructor.
* Only create a default constructor for classes that don't define one.
If a test expected an error and found at least one, it would not fail
on any other expected errors that didn't occur.
Also, some tests were expecting a compile time error message even though
the test script doesn't validate those (yet).
The test function was getting monolithic, so I went ahead and split it
into a separate little class.
Previously, fibers had a hard-coded limit to how big their stack size
is. This limit exists in two forms: the number of distinct call frames
(basically the maximum call depth), and the number of unique stack
slots.
This fixes the first half of this by dynamically allocating the call
frame array and growing it as needed. This makes new fibers smallers
since they can start with a very small array. Checking and growing as
needed doesn't noticeably regress the perf on the other benchmarks, and
it makes a new fiber benchmark about 45% faster.
The stack array is still hardcoded, but that will be in another commit.
-Wextra does several extra checks during the compiling. Unfortunately one of the extra check is for unused parameters.
Several functions have unused parameters (mostly the WrenVM* vm).
This makes it clear which files are part of the VM (i.e. the Wren library)
and which are part of the CLI. Makes a directory for the latter so it has
some room to grow.
This probably totally broke the VS project. If you can fix that, send me
a PR!
- "make all" builds all combinations of configurations
- Binaries are built to "bin"
- (For convenience, the release interpreter also goes in the top level dir)
- Libraries are built to "lib"
This will also make it easier to support building and testing other
configurations like Nan tagging versus union, computed goto, etc.
