Created attachment 81282 [details] testcase I've submitted a patch for review, which implements the proposal: https://gerrit.libreoffice.org/4465 I attach an HTML page with the new generated MathML code for the test case (as usual, you can open it in Firefox). Note that I've merged my fix for bug 66024 before working on this new bug because there could have been code overlap between the widehat/widevec/widetilde and the overstrike commands in SmXMLExport::ExportAttributes. However, I now think the two patches can apply independently. I've also prepared some changes to import menclose/mfrac@bevelled in the future. I don't plan to do that in that bug as I'm more concerned about the MathML export at the moment. Due the fact you already submitted a patch and are an expert on this domain, I mark this bug as NEW right away. Kind regards, Joren Marking these bugs assigned since I've already taken them. Frederic Wang committed a patch related to this issue. It has been pushed to "master": http://cgit.freedesktop.org/libreoffice/core/commit/?id=3b3ec32358aebd81ef5385f48dbf3ee4c93649e8 fdo#66086 - MathML export: wideslash, widebslash and overstrike The patch should be included in the daily builds available at http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours. More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback. |
Test case: {x wideslash y} newline {x widebslash y} newline overstrike {sometext} The result is <mtable> <mtr> <mtd> <mrow> <mrow/> </mrow> </mtd> </mtr> <mtr> <mtd> <mrow> <mrow/> </mrow> </mtd> </mtr> <mtr> <mtd> <mrow> <mrow> <mi mathvariant="italic">sometext</mi> </mrow> </mrow> </mtd> </mtr> </mtable> Proposal: - wideslash can be exported as <mfrac bevelled="true"> - There is not any <mfrac> equivalent for widebslash, so perhaps just use an <mo>\</mo>. - overstrike {sometext} can be exported as <menclose notation="horizontalstrike">.
