If -p flag is not set, we should bail on all three kinds
of errors, not just runtime errors. This includes
parse and compile errors. Before, parse and compile errors
were not properly affected by the :exit parameter to require, which
in turn caused scripts to not bail on parse or compile errors.
Using the new break special form, the loop
macro was cleaned up. Loop bindings are also
able to be used immediately after declaration, so
forms like (loop [x :range [0 10] :while (< x 5)] (print x)) will
now compile correctly.
Allow overriding functions in the core libray to provide better
functionality on startup. Used to include our getline function in
the repl but use a simpler version in the core library.
If a comment is not followed by a newline character, then
we got a false parse error. This is because the comment
state is left on the parse stack when we finished parsing, and
since the parse stack was not emtpy, we assumed an error.
This commit adds the parser/eof function, which lets the parser know
that an eof was reached. Before, we simply added a fake newline
character in some cases, and in the case of reading a file, we did
nothing, hence the bug.
This replaces a lot of the functionality in require by moving
it to module/find. module/native-paths and module/image-paths are also
merged into the one module/paths to make it easier to extend. This of
course breaks some of the less important API - module/native-paths no
longer exists.
Images are precompiled libraries. They can be created programmatically
via the `write-image` function and then loaded with `require` or
`import`. They can also be run by the command line tool - you must
specify the path to the image without the .jimage extension.
This should speed up start time and reduce malloc/free
usage to about 15% of what is what previously for startup.
The current cost is slightly larger binary as the representaion
of the image is currently less compact than source code.
There was an implementation for stacktraces in both
run.c and in core.janet, status-pp. The commit removes
the one in core.janet in favor of the C based stacktrace, which
is exposed via debug/stacktrace. Lots of reshuffling of run-context
ensued as well, which resulted in an api that is a bit cleaner.
The system path can more easily modified at runtime,
and the module/cache and module/loading tables are now exposed.
Properly cache native modules as well.
to make janet function calls easier and faster from C (still
needs an object pool for fibers, though). Fix bug in scan-number
and add many more peg tests.
