Hi devs, We need to decide what is the expected link reference serialization produced by the WYSIWYG editor when you create a link to a wiki page. I think we have to choose between 3 options: (1) Output untyped (ambiguous) link references whenever possible (2) Always output unambiguous (typed) link references (both 'doc:' and 'space:') (3) Always output 'doc:' link references (no 'space:' references) Let's see the details: = OPTION 1: Output untyped link references whenever possible = == <7.2 == Link from A.B * to A.WebHome (space home page) => [[WebHome]] * to A.C (same space) => [[C]] * to X.Y (different space) => [[X.Y]] * to X.WebHome => [[X.WebHome]] == 7.2+ == Link from A.B.WebHome * to A.WebHome (its parent) => [[space:A]] * to A.B.C or A.B.C.WebHome or A.C or A.C.WebHome (child or sibling) => [[C]] (very ambiguous) * to A.B.C.D or A.B.C.D.WebHome (nested page two levels or more below) => [[.C.D]] (ambiguous) * to A.C.D or A.C.D.WebHome (nested page under sibling) => [[A.C.D]] (ambiguous) * to X.Y.Z or X.Y.Z.WebHome => [[X.Y.Z]] (ambiguous) Link from A.B (terminal) * to A.WebHome (its parent) => [[space:A]] * to A.C or A.C.WebHome (sibling) => [[C]] (ambiguous) * to A.C.D or A.C.D.WebHome (nested page under sibling) => [[A.C.D]] (ambiguous) * to X.Y or X.Y.WebHome => [[X.Y]] (ambiguous) Link from A.B.C (terminal) or A.B.C.WebHome * to A.B.WebHome (its parent) => [[A.B]] (ambiguous) PROS: * shorter link references * hides WebHome from source syntax on 7.2+ CONS: * ambiguous link references * complex code * different output for <7.2 and 7.2+ in case of top level space [[WebHome]] or [[A.WebHome]] vs. [[space:A]] (we need to check if support for nested spaces is available) = OPTION 2: Always output unambiguous link references = == <7.2 == Link from A.B * to A.WebHome (space home page) => [[doc:WebHome]] (relative) * to A.C (same space) => [[doc:C]] (relative) * to X.Y (different space) => [[doc:X.Y]] * to X.WebHome => [[doc:X.WebHome]] == 7.2+ == Link from A.B.WebHome * to A.WebHome (its parent) => [[space:A]] * to A.B.C (terminal child) => [[doc:C]] (relative) * to A.B.C.WebHome (non-terminal child) => [[space:A.B.C]] (absolute) * to A.C (terminal sibling) => [[doc:A.C]] * to A.C.WebHome (non-terminal sibling) => [[space:A.C]] * to A.B.C.D (terminal descendant) => [[doc:.C.D]] (relative) * to A.B.C.D.WebHome (non-terminal descendant) => [[space:A.B.C.D]] (absolute) * to A.C.D (terminal descendant of sibling) => [[doc:A.C.D]] * to A.C.D.WebHome (non-terminal descendant of sibling) => [[space:A.C.D]] * to X.Y.Z => [[doc:X.Y.Z]] * to X.Y.Z.WebHome => [[space:X.Y.Z]] Link from A.B (terminal) * to A.WebHome (its parent) => [[space:A]] * to A.C (terminal sibling) => [[doc:C]] (relative) * to A.C.WebHome (non-terminal sibling) => [[space:A.C]] (absolute) * to A.C.D (terminal descendant of sibling) => [[doc:.C.D]] (relative) * to A.C.D.WebHome (non-terminal descendant of sibling) => [[space:A.C.D]] * to X.Y => [[doc:X.Y]] * to X.Y.WebHome => [[space:X.Y]] Link from A.B.C (terminal) or A.B.C.WebHome * to A.B.WebHome (its parent) => [[space:A.B]] (absolute) PROS: * unambiguous link references ("what you link is what you get") * slightly less complex code (but still complex) * hides WebHome from source syntax on 7.2+ CONS: * longer link references (because of "doc:" and "space:" prefixes) * cannot specify relative 'space:' references * different output for <7.2 and 7.2+ in case of [[doc:WebHome]] vs. [[space:A]] = OPTION 3: Always output 'doc:' references = == <7.2 == Link from A.B * to A.WebHome (space home page) => [[doc:WebHome]] (relative) * to A.C (same space) => [[doc:C]] (relative) * to X.Y (different space) => [[doc:X.Y]] * to X.WebHome => [[doc:X.WebHome]] == 7.2+ == Link from A.B.WebHome * to A.WebHome (its parent) => [[doc:A.WebHome]] * to A.B.C (terminal child) => [[doc:C]] (relative) * to A.B.C.WebHome (non-terminal child) => [[doc:.C.WebHome]] (relative) * to A.C (terminal sibling) => [[doc:A.C]] * to A.C.WebHome (non-terminal sibling) => [[doc:A.C.WebHome]] * to A.B.C.D (terminal descendant) => [[doc:.C.D]] (relative) * to A.B.C.D.WebHome (non-terminal descendant) => [[doc:.C.D.WebHome]] (relative) * to A.C.D (terminal descendant of sibling) => [[doc:A.C.D]] * to A.C.D.WebHome (non-terminal descendant of sibling) => [[doc:A.C.D.WebHome]] * to X.Y.Z => [[doc:X.Y.Z]] * to X.Y.Z.WebHome => [[doc:X.Y.Z.WebHome]] Link from A.B (terminal) * to A.WebHome (its parent) => [[doc:WebHome]] (relative) * to A.C (terminal sibling) => [[doc:C]] (relative) * to A.C.WebHome (non-terminal sibling) => [[doc:.C.WebHome]] (relative) * to A.C.D (terminal descendant of sibling) => [[doc:.C.D]] (relative) * to A.C.D.WebHome (non-terminal descendant of sibling) => [[doc:.C.D.WebHome]] (relative) * to X.Y => [[doc:X.Y]] * to X.Y.WebHome => [[doc:X.Y.WebHome]] Link from A.B.C (terminal) * to A.B.WebHome (its parent) => [[doc:WebHome]] (relative) Link from A.B.C.WebHome * to A.B.WebHome (its parent) => [[doc:A.B.WebHome]] (absolute) PROS: * unambiguous link references ("what you link is what you get") * relative references for nested non-terminal descendants * same output for <7.2 and 7.2+ * simpler code (easier to maintain) CONS: * doesn't hide WebHome from source syntax * longer link references (because of "doc:" prefix and "WebHome" suffix) I don't like ambiguous links so I'm against option (1). I don't think the WYSIWYG editor users care too much about the wiki syntax (option 2), as I commented on http://jira.xwiki.org/browse/XWIKI-13083, so I'm +1 for option (3). WDYT? Thanks, Marius
