471269a374 Define BOOST_PARSER_SUBRANGE, and use it consistently. subrange.hpp is now 
only included in C++17 builds.

Fixes #69.

3e7812ebe5 Simplify detail::is_variant and remove enable_variant. Turns out 
detail::is_variant_v is not actually used, except in one place in the printing
code, and it's not even essential there.

69e4f47bff Work around the busted-ass static_asserting op<< in boost::optional by 
recognizing all enabled optionals, and printing them the same as we do
std::optional.  Applied the same logic to variants too, for consistency.

c8ce2cace5 Add a special seq_parser combining rule that makes a std::string ot of two 
adjacent char/char32_t values.

Partially addresses #55.

b6ffe5fbe3 Change detail::sequence_of and detail::container_and_value_type so that they 
generate std::strings from repeated char32_ts and combine char32_ts with
adjacent strings.  Update docs accordingly.

Partially addresses #55.

cd284572c9 Add support for parsing into attributes whose types are optionals or variants 
other than the ones from std:: (e.g. boost::optional, boost::variant, and
boost::variant2::variant).

Fixes #53.

745b1b151d Add a small example to the parser test that shows that you do not need Sprit 
2's hold[] directve.  Fix an error exercised by the example.

3ebbd9e08c Correct an error in repeat_parser's choice of attribute. Sometimes it is 
necessary to use the value_type of the container out-param, rather than the
attribute generated by the subparser.

Fixes #52.

Zach Laine
2b0053bf83 Add no_case[] directive, and associated changes to char, string, and boolean 
parsers to make it work; uses the recently-added Unicode case-folding
operation.  Needs docs.

Fixes #44.

f34f096c66 Add logic to repeat_parser analogous to the logic in seq_parser, to enable 
implicit tuple <-> struct conversions.

d0fe18b61d Add single-code point Unicode case folding function; data and tests are 
generated from CaseFolding.txt.

Partially addressed #44.

Zach Laine
d60d33e40b Finish implementing support for parsing into structs as if they were tuples. 
This makes it possible to map from sequence parsers onto structs with no
semantic actions.  Also, add a doc section describing how parsing structs
works (including a couple of short example programs).

Fixes #45.
Partially addresses #28.

0e78ea2d26 Remove the T >> T -> std::vector<T> attribute combining rule from seq_parser. 2024-01-03 02:04:04 -06:00
Zach Laine
7883b8ed1e Update docs to reflect the new detail::sequence_of<T> semantics (std::string 
for sequence of char, std::vector<T> for everything else).  Also, update one
of the examples to match the associated test code.

Partially addresses #36.

f08255cf94 Use a tuple instead of a pair in seq_parser::{make_temp_result,combine}. Add a 
third tuple to the output of make_temp_result; this tuple is true/false values
indicating whether this parser's attribute was merged with an adjacent
parser's container of attributes of the same type.

Fixes #36.

2020e44fda Radically change the way that repeat_parser generates a sequence of 
attributes.  It now produces std::string when Attribute is char, and
std::vector<Attribute> otherwise (except for nope special-casing of course).

Partial fix for #36.

24d18b4eaf Remove the documentation section "An Odd Case", which was obviated by the 
previous commit.  Also remove the test cases that exercised that case.

d34d4b7e6a Remove the seq_parser C<T> >> C<T> -> C<T> collapsing rule. Add special logic 
for recursive rules to make accumulating recursive parsers like
recursive_string_rule in the parser_rule test easier to write.
