<glazou_pain> dsinger: you have to use /invite, that's what I did

<glazou> so we have regrets from szilles, anne, molly, dbaron and probably plinss too

<glazou> hi ChrisL

hi daniel

<dsinger> Which module?

<scribe> scribenick: chrisl

column-break

<fantasai> http://lists.w3.org/Archives/Public/www-style/2009Apr/0490.html

http://lists.w3.org/Archives/Public/www-style/2009Apr/0270.html

am: showed three combinations in an email
... page-break-avoid and column-break-avoid, all combinations make sense
... supposr 2 col layout, something is a column and a half wide
... if we had two separate properties, column-break-avoid would make it start in the second column
... page-break-avoid would move it to the next page
... if they were totallyy separate
... however, a single break property would move things to the next column but not necessarily the next page

dg: so you would get a blank page

am: or a blank column before the next page break

<fantasai> break-inside: avoid | avoid-column | avoid-page

<fantasai> would give you all combinations

am: if we think page break is always a column break, then its hard to say thata page break is avoided but ok to start im mid column
... close to the opinion that its okay to have separate column and page properties

el: one property (as above) would do it as well as long as all combinations are listed

<dsinger> Can we lay out all cases? Near end of girst col, near end of second

<dsinger> Pb avoid, cb avoid

<dsinger> Pb+cb avoid?

am: advantage of separate properties is that you avoid first column breaks then page breaks

dg: also an issue of readability

el: can be readable with one property, with good choice of values. encourages people to think about pages when designing columns

<dsinger> A break over page would violate cb avoid?

dg: these are being confused

bb: more interesting question, they are semi independent so all combinations need to be considered either way

dg: some comninations will be unused

bb: is there a list of all the combinations?

am: email did not listall of them

<glazou> http://lists.w3.org/Archives/Public/www-style/2009Apr/0054.html

dg: avoid means 'try to avoid'

am: most common pattern is to avoid all breaks.

dg: column should take precedence over pages

am: some people think there are only two combinations, but differ on which two those are

el: happy to define all three

am: avoid colum, page, both makes sense to me

bb: agree with elika, define all three even though one is not useful
... avoid-both is ok, if you avoid a column break also avoids a column break

el: no, avoiding both means you prioritise avoiding page breaks over column breaks

<glazou> ok

<dsinger> right, col1 of page 2 is not col2 of page 1

cl: a page break always produces a new colum break

bb: if its too long then there is no need to push it anywhere

am: avoid is not forbid. its 'attempt to not break"

cl: no way to say 'minimise the total number of breaks'

am: good point, can be complex to optimise for that though

sg: see example with avoid-column

<fantasai> am: I would prefer to specify that you try to lay out, and if it doesn't fit, you push to the top of the next column

am: choice of keeping "most" of the article together
... prefer a break art the end rather than a break near the start
... page break is always a column break as well. that has to be made clear

el: i agree with alex. want avoid to mean 'try layout then push over a break'. more complex stuff needs different keeywords. avoid behaviour is simple and useful so is what we should do now

bb: seems fine

dg: seem close to consensus

el: page break inside option does not work,
... introducing a shorthand that combines both column and page is the best option

am: cleaner solution to forget the old property

el: have to support the old property

am: yes but avoid in new documents

<fantasai> http://lists.w3.org/Archives/Public/www-style/2009Apr/0270.html

(consensus seems to be reached)

<fantasai> el: We're down to either alias or shorthand

el so we eliminate the first of melindas options but have to choose between 2 and 3

bb: shorthand seems like overkill

am: fine with either

dg: would like to see a summing up and final proposal

el: can work with hakon to propose something that covers all three combinations, need to pick 2 or 3

2. Add three new column-breaking properties ('column-break-before', 'column-break-after', 'column-break-inside') and define their interactions with the existing page-breaking properties; also define three shorthands ('break-before', 'break-after', 'break-inside') that would set both page- and column-breaking values. Consider deprecating both page- and column-breaking properties in the future.

3. Define 'break-before', 'break-after', and 'break-inside' as aliases to 'page-break-before', 'page-break-after', and 'page-break-inside'.

am: does the alias mean all the values apply to the old properties?

el: no, one is a superset of the others

am: preferable from an implementor standpoint to allow all the properties

el: 'always' value would be a problem

am: ok so i prefer a new set of properties

el: so do I

cl: so everyone seems to like melindas option 2 best

resolution: Add three new column-breaking properties per melindas email oprtion 2 http://lists.w3.org/Archives/Public/www-style/2009Apr/0270.html

<fantasai> /resolution/RESOLVED/

<scribe> ACTION: fantasai work with hakon on spec text to define the column-break properties and interaction with page bbreak properties [recorded in http://www.w3.org/2009/04/29-CSS-minutes.html#action01]

<trackbot> Created ACTION-141 - Work with hakon on spec text to define the column-break properties and interaction with page bbreak properties [on Elika Etemad - due 2009-05-06].

email from svg on image fit

<glazou> http://lists.w3.org/Archives/Public/www-style/2009Apr/0490.html

"The naming was briefly discussed in another SVG telcon[1], and the conclusion was that the SVG WG prefers the naming 'content-fit' and 'content-position' because of the reasons already mentioned above.

"

el: concern is that for css, this only appies to images while the name implies it applies more widely eg to text content
... but cant comu up with a better name

dg: don't see a clash with the content property, but could live with it

el: wonder if we should ask for better names

dg: ack the problem and ask for a better name

<scribe> ACTION: daniel respond to http://lists.w3.org/Archives/Public/www-style/2009Apr/0490.html agreeing there is a problem but asking for a better name [recorded in http://www.w3.org/2009/04/29-CSS-minutes.html#action02]

<trackbot> Created ACTION-142 - Respond to http://lists.w3.org/Archives/Public/www-style/2009Apr/0490.html agreeing there is a problem but asking for a better name [on Daniel Glazman - due 2009-05-06].

almost-ready specs

dg: what can we move to PR?
... chris reported progress with implementations agfainst the colour module tests
... we are seen as very slow and need to publish and move forward
... other candidates?

el: namespaces?
... a parsing bug and one test is failing

dg: all implementations fail?

dg; who is doing implementation reports?

el: easy to do once implementations pass, test suite is not very long

dg: discussed media queries with anne, he thinks some will be untestable as we do not have suitable devices and that testing on desktop is enough
... concerned that we need to test on mono and character-cell devices
... desktop ones seem to be interoperable at this time, but some features do not apply

el: do we have any implementations for grid?

dg: no

el: should make an imp report for dersktop and survey what other devices actually exist. at end of 6 months if there are no implementations of some features or devices we can drop them from the spec

bb: not honest to say we pass a test if there are no implementations
... some implementatiosn can emullate and always pass
... currently no features at risk

cl: prefer to do an imp report then mark features at risk and republish

sz: only need to claim to be a device, not to actually be that device

dg: yes but not implementation claims to be a grid for example

sz: only issue in testing is if the right selection was made, not whether it then goes on to lay outcorrectly

dg: will not agree to implement like that and claim to have a feature that they in fact don't have

<Bert> If we test '@media (grid)' and '@media not (grid)' and Opera does the right thing for both, sin't that enough?

dg: can test for not-grid

el: probably sufficient.
... will have to say its sufficient

dg: anne had some tests for desktop only. no tests for other devices. WG should look at tests from Anne and contribute more
... as soon as we have tests, we can move forward

cl: where are anne's tests?

<Bert> http://tc.labs.opera.com/mediaqueries/

not listed on http://www.w3.org/Style/CSS/Test/

bb: because not reviewed yet

dg: will try to review for next week

cl: cdf testsuite has media query tests which could be re-used

sz: snapshot?

el: depends on 2.1 and selectors

sz: snapshot is important as it actually defines the current state

dg: don't think the snapshot is very useful

<dsinger> well, there will be browsers that are interoperable on defined modules...

<dsinger> bye
