Extend jv_number to use decNumber for storing number literals. Any math
operations on the numbers will truncate them to double precision.
Comparisons when both numbers are literal numbers will compare them
without truncation.
Delay conversion of numbers to doubles until a math operation is performed,
to preserve precision. A literal jv_number will only need conversion to
double once, and will reuse the resultant double on subsequent
conversions.
Outputting literal jv_numbers preserves the original precision.
Add strong pthread requirement to manage contexts/allocations for
converting numbers between their decNumber, string, and double formats.
Also flex is now optional.
The outputs of flex and bison are now committed. By default they get
built, but users who want to build from git can now
./configure --disable-maintainer-mode
to turn off the dependency on bison and flex.
Maintainers must, of course, commit the bison and/or flex outputs when
they make changes to parser.y and/or lexer.l, respectively.
The search path listed in an import directive can now be an array. The
top-level search path is appended. Null and empty strings in the path
terminate any search. The "." in "." and "./*" is replaced with the
directory containing the file doing the import (for command-line
programs this is the current directory, though that may be a bad idea).
No version numbers or anything of the sort are gratuitously added to the
search paths.
All this makes external package managers possible by allowing
dependencies to be installed local to dependents.
- Build binaries for multiple platforms
- Make a manpage out of the manual (see #19)
- Extract more tests from the documentation
- Fix a few documentation bugs uncovered by above.
