Author	SHA1	Message	Date
Andrey Semashev	4b40364d6d	Work around compilation errors on clang-10 through 12.	2024-10-11 01:04:21 +03:00
Andrey Semashev	7c55a6cef8	Marked output_proxy assignment as const. This is also required for compliance with std::output_iterator concept.	2024-10-11 00:34:28 +03:00
Georgiy Guminov	1ea8087623	Check for compliance with output_iterator in function_output_iterator_test.	2024-10-11 00:29:20 +03:00
Andrey Semashev	e4eaeeac44	Make function_output_iterator compliant with std::output_iterator concept. Fixes https://github.com/boostorg/iterator/issues/85. Closes https://github.com/boostorg/iterator/pull/87.	2024-10-11 00:26:30 +03:00

René Ferdinand Rivera Morell	ce030ab2c3	Add support for modular build structure. (#84 ) * Make the library modular usable. * Switch to library requirements instead of source. As source puts extra source in install targets. * Remove not-needed reference to Conversion dependency. * Add missing b2 testing module import. * Add requires-b2 check to top-level build file. * Bump B2 require to 5.2 * Change all <source> references to <library>. * Update copyright dates. * Move inter-lib dependencies to a project variable and into the build targets. * Update build deps.	2024-08-19 01:22:08 +03:00

Andrey Semashev	7968dd3ea8	Replaced actions/checkout usage with manual download commands. This fixes the deprecation warnings for actions/checkout@v3. actions/checkout@v4 is not functional because of the upstream bug: https://github.com/actions/checkout/issues/1590	2024-02-06 00:17:16 +03:00
Andrey Semashev	dfe11e7144	Removed one more $ tag.	2024-01-03 01:43:52 +03:00
