%description    devel
gstr is a single-header UTF-8 string library for C providing grapheme-aware
functions that operate on what users perceive as characters, not bytes.
Handles emoji, CJK, combining marks, and all Unicode correctly using UAX #29
grapheme cluster segmentation and Unicode 17.0.0 character property tables.
Zero dependencies.

61 functions in two layers:

UTF-8 layer (15): utf8_decode, utf8_encode, utf8_valid, utf8_next, utf8_prev,
utf8_cpcount, utf8_next_grapheme, utf8_prev_grapheme, utf8_cpwidth,
utf8_charwidth, utf8_is_zerowidth, utf8_is_wide, utf8_truncate,
gstr_is_unicode_punctuation, gstr_is_whitespace_cp

Grapheme layer (46): gstrlen, gstrnlen, gstrwidth, gstroff, gstrat, gstrcmp,
gstrncmp, gstrcasecmp, gstrncasecmp, gstrstartswith, gstrendswith, gstrchr,
gstrrchr, gstrstr, gstrrstr, gstrcasestr, gstrcount, gstrspn, gstrcspn,
gstrpbrk, gstrsub, gstrcpy, gstrncpy, gstrcat, gstrncat, gstrdup, gstrndup,
gstrsep, gstrltrim, gstrrtrim, gstrtrim, gstrrev, gstrreplace, gstrlower,
gstrupper, gstrellipsis, gstrfill, gstrlpad, gstrrpad, gstrpad, gstrwtrunc,
gstrwlpad, gstrwrpad, gstrwpad, gstr_is_whitespace, gstr_is_whitespace_ascii

# Run the assertion-based test suites (they use the shared test_macros.h, need
# test/ on the include path, and return non-zero on failure). The grapheme-walk
# binary is intentionally excluded: it is a diagnostic visualization tool that
# always exits 0 (so it gates nothing) and prints raw, deliberately invalid
# UTF-8 to demonstrate malformed-input handling, which aborts the
# unbuffer/expect wrapper that COPR runs the build under.

%changelog
* Thu Jun 25 2026 Edward J Edmonds <edward.edmonds@gmail.com> - 3.0.1-2
- Drop the grapheme-walk diagnostic from %%check: it always exits 0 (gates
  nothing) and prints raw invalid UTF-8 that aborts COPR's unbuffer/expect
  build wrapper. The five assertion suites still run and gate the build.

* Thu Jun 25 2026 Edward J Edmonds <edward.edmonds@gmail.com> - 3.0.1-1
- Update to 3.0.1 (packaging metadata fix; library header unchanged from 3.0.0)
- Upstream now ships the canonical project URL in gstr.pc.in, so drop the
  spec-side URL override when generating the pkg-config file

* Thu Jun 25 2026 Edward J Edmonds <edward.edmonds@gmail.com> - 3.0.0-1
- Update to 3.0.0
- Add Unicode punctuation/symbol classification (gstr_is_unicode_punctuation,
  CommonMark 0.31.2 definition) and Unicode White_Space classification
  (gstr_is_whitespace, gstr_is_whitespace_ascii, gstr_is_whitespace_cp)
- Update Unicode character property tables to Unicode 17.0.0
- Ship a pkg-config file (provides pkgconfig(gstr))
- Use the canonical project URL (github.com/deths74r/gstr) for URL, Source0,
  and the generated pkg-config file
- Run the full test suite (6 suites) in %%check
- Drop obsolete gstr-zig removal from %%prep (no longer present in the source)

* Wed Feb 11 2026 Edward J Edmonds <edward.edmonds@gmail.com> - 2.0.2-3
- Make main package archful so tests run on all architectures in koji
- Move detailed description to devel subpackage
- Add %%{optflags} to test compilation in %%check
- Disable debuginfo generation (header-only library has no compiled binaries)
- Add SPDX license headers to source files and README.md

* Fri Jan 23 2026 Edward J Edmonds <edward.edmonds@gmail.com> - 2.0.0-1
- Initial package
