--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by David Malcolm <dmalc...@gcc.gnu.org>: https://gcc.gnu.org/g:1a2c62212bd912f5c8130e992ce282b542599f98 commit r16-487-g1a2c62212bd912f5c8130e992ce282b542599f98 Author: David Malcolm <dmalc...@redhat.com> Date: Thu May 8 20:41:35 2025 -0400 diagnostics: convert HTML output test plugin to 'experimental-html' sink [PR116792] In r15-3752-g48261bd26df624 I added a test plugin that overrode the regular output, instead emitting diagnostics in crude HTML form. In r15-4760-g0b73e9382ab51c I added support for multiple kinds of diagnostic output simultaneously, adding -fdiagnostics-add-output=DIAGNOSTICS-OUTPUT-SPEC -fdiagnostics-set-output=DIAGNOSTICS-OUTPUT-SPEC for adding/changing the kind of diagnostics output, supporting "text" and "sarif" output schemes. This patch promotes the HTML output code from the test plugins so that it is available from "-fdiagnostics-add-output=", using a new "experimental-html" scheme, to allow simultaneous text, sarif and html output, and to make it easier to experiment with. The patch adds Python-based testing of the emitted HTML. The patch does not affect the generated HTML, which is still crude, and not yet ready for end-users. I hope to improve it in followups. gcc/ChangeLog: PR other/116792 * Makefile.in (OBJS-libcommon): Add diagnostic-format-html.o. * diagnostic-format-html.cc: Move here from testsuite/gcc.dg/plugin/diagnostic_plugin_xhtml_format.cc.
