I spent a couple hours already looking into this. The closest I could come to a working model using a scripting language was this: https://mail.gnome.org/archives/gnumeric-list/2015-November/msg00001.html which doesn't actually work. When I try it using python (aka python2.7) I observe: >> Traceback (most recent call last): >> File "./gnumeric-introspection", line 4, in <module> >> gi.require_version('GOffice','0.10') >> AttributeError: 'module' object has no attribute 'require_version' or using python3 (aka python3.5) it doesn't even get that far. I observe: >> Traceback (most recent call last): >> File "./gnumeric-introspection", line 3, in <module> >> import gi >> File "/usr/local/lib/python3.5/dist-packages/gi/__init__.py", line 39 >> print url >> ^ >> SyntaxError: Missing parentheses in call to 'print' Also, the closest I could come to useful documentation was this: https://lazka.github.io/pgi-docs/Gnm-1.12/classes.html https://lazka.github.io/pgi-docs/Gnm-1.12/classes/Workbook.html etc. which AFAICT makes no mention of saving a graph, or even inspecting the structures within a graph. -- Are there any working examples of gnumeric introspection that could be used as a model? -- Where should one look for documentation? -- Or would it be better to give up on introspection and just write in C, using ssconvert.c as a model? ======================= Also, given a workbook with multiple sheets and multiple graphs per sheet, what is the proper way to identify a particular graph? In .svg format, the objects have id="whatever" attributes, but AFAICT in .gnumeric format they don't. I suppose one could add a title to each graph, using a zero-point font, and use that for identification. Is there a better way? This may be related to the code in ssconvert.c where it says: >> * HACK: (bug 694408). >> * >> * We don't have a good way of specifying the >> * sheet. https://bugzilla.gnome.org/show_bug.cgi?id=694408 _______________________________________________ gnumeric-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/gnumeric-list
