Passing nullptr to functions with nullable parameter (`*parent = nullptr`) crashes

1

For this kind of interface: ```cpp TreeItem *create_item(TreeItem *parent = nullptr, int32_t idx = -1); ``` Current `binding_generator.py` generates implementation like below: ```cpp TreeItem *Tree::create_item(TreeItem *parent, int32_t idx) { /*...

String::String(const char*) is expecting latin1 instead of UTF-8

7

Since #695, `String::String(const char*)` is now internally calling `string_new_with_latin1_chars` instead of `string_new_with_utf8_chars`. diff: https://github.com/godotengine/godot-cpp/commit/bf8fc4c53d07cf8ac4d8343364899c197076fbc2#diff-20a0dfd8072691f654c12adb6aecabee9d3247fb99488b37539dab1d967c97b8L77-L79 Because of this change, we can't pass non-latin1 characters for String-like parameters anymore. For example, `node->get_node("Path/To/NonLatin1/名前")`...

These are definetely evil: ``` cpp #ifndef PI #define PI 3.14159265358979323846 #endif #ifndef TWO_PI #define TWO_PI 6.28318530717958647693 #endif #ifndef M_TWO_PI #define M_TWO_PI 6.28318530717958647693 #endif #ifndef FOUR_PI #define FOUR_PI 12.56637061435917295385 #endif...

Custom debug handler support for X3

5

In Spirit.Qi, we had `qi::debug(...)` function for specifying custom debug handler. https://github.com/boostorg/spirit/blob/889babc3839e12ac0bba448ecd7150956d17c783/include/boost/spirit/home/qi/nonterminal/debug_handler.hpp#L75-L123 However in X3's current implementation, `simple_trace` is hard-coded: https://github.com/boostorg/spirit/blob/889babc3839e12ac0bba448ecd7150956d17c783/include/boost/spirit/home/x3/nonterminal/detail/rule.hpp#L60-L91 I'd love to see custom debug handler support in...

X3: recursive rules reach template instantiation limit too quickly?

13

I was writing JSON-like grammar which have many popular types, such as "Int", "Float", "String", "Variable", "Array", etc. In my X3 grammar, the content of "Array" rule contains "Variable", and...

x3::unicode::lit does not take single unicode character literal

3

These two both work: ```cpp // defined in boost/spirit/home/x3/string/literal_string.hpp auto const dollar_def = x3::standard::lit("$"); // double quotes // `lit` delegates to: boost/spirit/home/x3/char/char.hpp auto const dollar_def = x3::standard::lit('$'); // single quotes...

X3 lacks boolean parser for unicode char type

8

I think we could provide simple typedefs in EDIT: `bool_policies` must be updated too; however there's some hard-coded string literals in bool_policies.hpp which simply do not match the unicode char...

I've recently started adding `boostorg/boost` as a git submodule for my own application. After experimenting, I've discovered that doing so will make your `git status` commands very slow (here ~3secs;...
