The test makes more sense in step6.
Thanks to kanaka for the read-string suggestion.
Introduction of tail call optimization in step5 was making let* affect
the parent environment. This was partially fixed in later steps.
Introduction of macros in step8 was breaking the evaluation of an
empty list. This was fixed by step 9 but never backported.
Add a step1 test to make sure that implementations are properly
throwing an error on unclosed strings.
Fix 47 implementations and update the guide to note the correct
behavior.
Fixes made to: ada, c, chuck, clojure, coffee, common-lisp, cpp,
crystal, d, dart, elm, erlang, es6, factor, fsharp, gnu-smalltalk,
groovy, guile, haxe, hy, js, livescript, matlab, miniMAL, nasm, nim,
objc, objpascal, ocaml, perl, perl6, php, plsql, ps, python, r,
rpython, ruby, scheme, swift3, tcl, ts, vb, vimscript, wasm, yorick.
Catchless try* test is an optional test. Not all implementations
support catchless try* but a number were fixed so they at least don't
crash on catchless try*.
- Add */run script for every implementation.
- Refactor Clojure build to allow individual jar files for each step.
- Update FFI version for es6 and miniMAL to work with newer node
versions.
The run scripts for the following could use some additional
refactoring:
- java: build individual step jar, use java -jar instead of mvn to run
- plpgsql: maybe combine plpgsql/run and plpgsql/wrap.sh
- vhdl: combine vhdl/run and vhdl/run_vhdl.sh
- vimscript: combine vimscript/run and vimscript/run_vimscript.sh
- Remove most of the step5 excludes in the Makefile except for ones
which don't have TCO capability at all (or the implementation is too
slow): bash, make, mal, matlab.
- Make perf_EXCLUDES consistent with other excludes.
- Add a print-FOO target which prints the resolved value of Makefile
variable FOO. For example, `make print-IMPLS` to print the list of
implementations.
The input string `(prn "abc` caused the nim implementaion (from step1
onwards) to enter an endless loop in tokenize (which eventually caused
out-of-memory).
The fix verfies that indeed the regex matches a non-empty substring
before adding that substring as a token.
