Hi Francois, There have been a few threads about this on the plumbing mailing list, and there's an ongoing thread on Github as well.
https://github.com/Prismatic/schema/pull/134#issuecomment-52088191 The upshot is that it's a fundamental limitation of `either` that it can't provide good error messages, because it doesn't know which schema any particular data is "supposed to" be validated against. I would highly encourage you to use `s/if`, `s/cond`, or other options instead -- they will provide much better error messages out of the box, and are more efficient to boot. FWIW, `either` used to actually print the schemas as you mention, but we actually found that in most cases it made errors *more difficult* to understand because the list of huge schemas obscured the context of the error, which was typically much more useful. -Jason On Wed, Aug 13, 2014 at 6:19 AM, François Rey <fmj...@gmail.com> wrote: > The resulting message is generated by the walk method of the s/Either > record, see this line: > > https://github.com/Prismatic/schema/blob/ce582d1602abde47143a618745cdd079e0cdaf44/src/cljx/schema/core.cljx#L437 > > Perhaps removing the quote before 'schemas would make the message clearer: > > (list 'some (list 'check '% (utils/value-name x)) schemas)) > > > That would be a quick fix to avoid a strange message, and may have been > what was intended originally (typo bug?). > Otherwise one would have to change the logic, perhaps by accumulating the > result of walking each contained schema and combine them perhaps like this: > > (conj 'or res) > > > the idea being to display a list of test for each schema or'ed together. > > I'm copying this in the prismatic mailing list for the record, perhaps > Jason has further comments on this. > > François > > -- > You received this message because you are subscribed to the Google Groups > "Plumbing and Graph: the Clojure utility belt" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to prismatic-plumbing+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
