ed72dcf82d Rename the header <janet/janet.h> to <janet.h> 
Makes it easier to use and remember, and makes the
variable `module/*headerpath*` make more sense.

1e70c97ef0 Allow enabling/disabling of peg module. 
Use compiler define -DJANET_NO_PEG to turn off the peg module.

6d5ff43de7 Make amalg build cleaner. 
Don't pull in a global header <janet/janet.h> unless we need to.

fe27df528c Boot core library from image rather than source 
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.

19e59705b9 Main rule in peg is always 0 
After we changed peg bytecode emission to
preallocate space for an instruction before
emitting sub rules, the rules are numbered
in the order that they are compiled. This means
that the main rule is always 0.
We can remove the explicitly stored main rule in
the peg structure.

611543c48b Add source amalgamation 
The amalgamated source concatenates all sources
to a file janet.c which can be used for
embedding janet, much in the same way as sqlite
or mongoose.

b4934ceddc Make parser errors a bit better for files with no closing 
delimiters.

c4114fbcdb Add quote special to peg syntax to make captures terser. 2019-01-17 19:28:42 -05:00

95f2bbe0a0 Add highlight.janet tool which can highlight 
janet source code and output html or terminal escaped code.
Also made re entrant calls into the vm provide better
error messages.

612a245961 More work on peg. Disable indexed backrefs and replace substitution 
with accumulation.

d0fc29338c Add error special form in Peg to allow construction of grammar errors 
for more useful grammars that could eventually be used in a compiler.

1304f9263b Update peg docs and make bad backrefs not error the whole pattern, but just cause the current match attempt to fail. 2019-01-14 21:47:55 -05:00

90313afd40 Update PEG documentation and peg syntax. 
Disable tail calls in the root scope for better
stacktraces, as the root scope may contain a single call
to a failing function, as in the case of the test suite.

d0ec89c7c1 Update Matchtime captures to not include all of the 
matched text automatically, and fix pattern recursion
in grammars.

192705113e Add Matchtime captures to peg (Equivalent to LPegs lpeg.Cmt). 
This allows that pattern to call an external function to
check if some text should match or not. This allows for
matching any possible language a computer can recognize.

ff0d3a0081 Compile pegs to bytecode with (peg/compile). Peg 
performance is improved, and peg syntax has been expanded with a few
more keywords.

798c88b4c8 Update peg to allow functions over captures. Update C API 
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.

83f4a11bf3 Add some more tests, add parameterized captures to patterns, 
and fix some bugs.

d7626f8c57 Add more capturing capabilities including substitutions, as well 
as back references for PEGs. More documentation is needed for PEG
syntax, but the amount required will need an external document, not
just a docstring.

no captures, so not yet ready.
