Preview for "Update"

by ww (Archbishop)
on Dec 05, 2012 at 22:40 UTC ( #1007421=monkdiscuss: print w/replies, xml ) Need Help??

Brethern and Sistern (excuse the homo sap bias):

For the too-many-th time, I discovered after posting that I'd omitted a critical point, markup or something else that left me dissatisfied with the node and then turned myself into a serial updater by adding an error for every correction.

Therefore, seizing the bull by the bs ^H^H^H ... er, horns, may we discuss a possible change to the update capability; namely, an optional "preview before updating" configuration, which might be added to the option for direct posting without previewing which exists for Monks of certain orders?

Alternately, we might add a second, "preview" button to the existing "update" button and redirect the action that way.

And, actually I'm very curious about why this hasn't surfaced recently. It may be this has engendered little interest previously or that it's a fundamentally 'bad idea' or that it's in the 'too hard' box (but, without suggesting I'm sure I could do the job, I don't see why that would be the case).

What say you?

    Hi ww, and welcome to the monastery!

    May I direct your attention to the Search box that's located at the top-left corner of every page here at PerlMonks, and suggest that you try entering the term "preview update", and then click on the adjacent button :-)

    You may find this and this. And even this, which seems to suggest that we once had it, before somebody broke it and never got around to fixing it.

    Anyway, enjoy your time here at the monastery.
    Don't forget to always use strict; and use warnings;
    And whatever you do, never, NEVER forget to use your <code> tags!


      And '<grin> back at you, Monsignor and author of many wise posts' :-).

      Yes, we've both been around to see this one arise before: Your first cite is from 2008; the second from 2009 and the third from 2000. While those qualify as "recently" when discussing geological time -- or even when considering events of the last decade, neither seems to have appeared nor been acted upon more recently.

      And those treads illuminate some possibilities: for example using a (later discarded) draft-reply-to oneself (almut RIP) or an alternate of using one's my scratchpad (Cardinal moritz). Yup, that's an approach, but kludgy, IMO and certainly not a very direct way of facilitating a preview.

      f00li5h admits to using the same method I've (shamefacedly) described.

      So the state of affairs remains as decribed by bofh_from_oz in Preview for Node Updates? (2005, cited by jdporter in the thread beginning at No preview on Update of a Node?...) and perhaps summed up by tye in Re: Preview for Node Updates? ( duh :), which I understand to mean that he doesn't intend to make this a personal priority (which is scarcely faultable) and that we pmdevs (some, like me, of questionable skills to do other than deal with rendering) have left the idea lie fallow if not "dropped the ball" entirely.

      Hence, I thought some merit might exist in re-raising the issue, but since, to date (and hour), your response is the only one, perhaps this is an idea of no great interest to the majority of the Monks, even tho a large proportion of the active Monks began to visit the Monastery only after the last prior discussion....

      /me trails off, still hoping for more responses.

        Take a ++ to your OP as "I agree", at least from me.

    With or without a preview button, you will always discover a typo seconds after you hit the update button.

      Oh. uh... now I understand. I'd always thought that was Murphy twiddling the bits. :-)

      Even so, if its "a typo" that might be an improvement over my usual everlasting fountain of cascading errors.

        It has long been known that clicking "Print" introduces errors into hardcopy documents. Seems like we have a related effect with "Update".

    IMHO the 'preview' has great merit. I always read the node again after posting and I'm amazed how often I find typos and grammar errors.

    I especially find writing 'perl' for 'per' as one of my weaknesses :-)

    Just my 2 cents...
