[xwiki-devs] [Proposal] Define a set of User Experience guidelines for XWiki

by Guillaume Lerouge

Hi Devs, Following-up on Caty's email ( http://markmail.org/message/3vukpehxeiflfjfw) I'd like us to get a bit more organized when it comes to improving XWiki's User Experience. This would allow us to make the product better and to gather more feedback from the community (such as Thibaut's email, see http://markmail.org/message/3bdk4jaziuqs6zvi ). In order to make our product great I think it would be good for us to agree on a set of standards and best practices related to UX. There are 2 levels to this initiative: 1. Agree on a set of broad rules 2. Agree on the implementation specifics for each rule A broad rule is a general rule that has to be followed when designing & coding a new feature: 1. "Always design a feature with one or more specific personas in mind" 2. "Respect consistency -> all UI items in XWiki should look & behave in the same way" Specifics are details related to the implementation of any given rule: 1. Choose the style to use for all buttons (see http://incubator.myxwiki.org/xwiki/bin/view/Standards/ for examples) 2. Define the personas we're targetting (see http://dev.xwiki.org/xwiki/bin/view/Design/ImproveXWikiUserExperience for examples) I'd like to get your feedback on the following points: - Is that a good idea overall? - Do you think we can make it an integral part of our development process? If the feedback is positive I'll start a discussion about the general UX rules we should make XWiki follow, then new ones for the specifics of each rule once we've agreed on some or all of them. Thanks, Guillaume -- Guillaume Lerouge Product Manager - XWiki Skype: wikibc Twitter: glerouge http://guillaumelerouge.com/

[xwiki-devs] [Proposal] Making "Edit this attachment" an advanced feature in the advanced edit mode

by Silvia Rusu

Hi devs, I propose we make "Edit this attachment" in the "Attachments" tab an advanced feature in the advanced edit mode. When trying to use "Edit this attachment": - in IE you get the following message: "Could not initialize a required ActiveX object" - in FF 3.5.2 installing the extension delivers the following message:"FoxWiki 1.0b could not be installed because it is not compatible with Firefox 3.5.2". - installing the extension on an older version of FF requires additional configuration, which the average user may not know how to perform. Under the above circumstances I think "Edit this attachment" will cause confusion for the average user instead of providing a useful tool.

[xwiki-devs] [Proposal] Remove "History" from the "Choose editor" panel

by Silvia Rusu

Hi Devs, I propose we remove "History" from the "Choose editor" panel in Edit mode. If you look at the "Edit" entry in the XWiki action menu you will see the following sub-menus: - WIKI - WYSIWYG - INLINE FORM - PAGE ACCESS RIGHTS - OBJECTS - CLASS The entries in the "Choose editor" panel are all "Edit" sub-menus, except for "History". I think the "History" tab in View mode should be enough. WDYT?

You >can also use XEclipse which has syntax highlighting and some >autocompletion for velocity (you'd need to use the 1.2RC1 version). I can agree with that. Velocity might be the simplest language for you but for started I could not find a good Velocity language tutorial. Even though the support I get from IntelliJ is really helpful the strange syntax is making it difficult to code (return values through parameters for example) but the real difficulty comes from the fact that I cannot debug velocity in any efficient way but the real thing I cannot stand is the fact that Velocity just ignore any problems. This might be good for a simple web site but for an application like a blog this is not good in my view. At least with Groovy I have a fairly well defined language and some mailing lists that can help me with problems and it ensures that NPEs, undefined methods etc are handled. >> What I found out is that I was msot >> of the time better off rewriting stuff starting with small chunks >> rather >> than trying to take existing code and reuse it all at once.

I rather have a good, robust and reliable Blog application even if I would have to download it separately. But first I need to see how well a Blog in Groovy would work and what the limitations (like the programming rights) mean. To keep it easy I think I will start with implementing what we have in BlogSheet/BlogCode to just list the current entries in a blog. If I can then create a Blog Post Entry with Groovy I should pretty much be able to compare the two. Personally I am more interested to get the stuff going well for my own Blog but I am willing to go the extra mile to provide it to the community. Cheers - Andy

[xwiki-devs] [VOTE] Use PNG instead of GIF for the silk icons

by Sergiu Dumitriu

Hi devs, Short version: we need to replace GIFs with transparent PNGs for the Silk icon set. 3 options: A. use "filter: AlphaImageLoader" in our CSS, time consuming for our devs B. serverside content negotiation to send GIFs only to IE6, doesn't really fix the problem for IE6 C. use a third party library that handles this for us, but does not work under certain security restrictions Long version: Originally, silk icons are PNGs, with alpha transparency. The problem with them is that in IE6 they don't display nice, since they have a gray background. So, instead we're currently using GIFs, but this approach has some big issues: - GIFs are indexed, so they have at most 256 colors out of the millions possible in PNGs. This is not such a big issue, since most icons don't use so many colors. - PNGs are smaller (in bytes) than GIFs. - Since gifs don't have alpha transparency, they have an almost-white border around the colored pixels, which makes them ugly on non-white backgrounds (this is obvious on really dark backgrounds). This is a real blocker for using darker themes in Colibri. Now, switching to PNGs directly is not a good option, since most of our end users are (forced to be) using IE6. Some tricks are possible: A. Change the CSSs to contain a filter which enables the PNG transparency. This can be done in several ways: A1 - manually (hard for developers, breaks CSS validity) A2 - automatically at build time (breaks CSS validity) A3 - dynamically in the SkinAction (won't work if the CSS is served by the container) The advantage is that we can control which images are transformed. The disadvantage is that it might not work under certain security restrictions. B. Implement a kind of content-negotiation trick that sends PNGs or GIFs depending on the user agent. This is easy to do with a few Apache HTTPD settings, but it's not cross-platform at all. We can also do it in the SkinAction, but again, doesn't work if the request does not pass through it. The advantage is that it always works, since it's always an image. The disadvantage is that icons will continue to look ugly in IE6, since they are GIFs. C. Use http://www.twinhelix.com/css/iepngfix/ which automatically fixes all images in IE. The advantages are that it is the most easy solution to implement, with the least amount of effort, it fixes most problems, and requires little maintenance. The disadvantage is that it won't work under certain security restrictions, and that a clean and fast integration will requirer to add some mechanism of identifying which images to fix (it can be incompatible with other tools that do their own PNG fix, like Google Maps). None of the alternatives is perfect, but my personal preference goes to C. -- Sergiu Dumitriu http://purl.org/net/sergiu/
