I would like to add next plugin to Ikiwiki. It's `progressbar` or simply `progress`.
|
|
I'm not sure what plugin name better is, probably that shorter ;) I know that
|
|
[DokuWiki](http://wiki.splitbrain.org/plugin:progressbar) has similar plugin,
|
|
so I think it can be useful also for Ikiwiki users.
|
|
|
|
Here is proposition of the plugin syntax:
|
|
|
|
\[[!progress done=50]]
|
|
|
|
Of course, `done` argument is integer from 0 to 100.
|
|
|
|
A here is its HTML result:
|
|
|
|
<div class="progress">
|
|
<div class="progress-done" style="width: 50%">50%</div>
|
|
</div>
|
|
|
|
Note: I was trying with `<span>` tags too, but that tag is inline, so I can't
|
|
set `width` property for it.
|
|
|
|
> In the poll plugin, I ended up using a `<hr>` for the progress-like
|
|
> thing. One reason I did so is because it actually works in text-mode
|
|
> browsers (w3m, lynx), that do not support css or colorized
|
|
> divs. Since the hr is an element they display, just setting its width can
|
|
> make a basic progress-type display. The style then makes it display
|
|
> better in more capable browsers.
|
|
>
|
|
> The other advantage to that approach is that the htmlscrubber lets
|
|
> through the `class` and `width` fields, that are all that are needed for
|
|
> it to work. No need to work around htmlscrubber.
|
|
>
|
|
> So I suggest adapting this to use similar html. --[[Joey]]
|
|
|
|
>> I just had a brief play with this. It seems there are some trade-offs involved.
|
|
>> The `width` attribute of an `<hr>` tag is deprecated, but that's not the big one.
|
|
>> I can't see how to place text next to an `<hr>` tag. I note that in the
|
|
>> [[plugins/poll]] plugin there is text above and below the 'graph line', but none
|
|
>> on the same line as the graph. I prefer the way the current code renders,
|
|
>> with the percentage complete appearing as text inside the graph.
|
|
>>
|
|
>> So, if we use `hr` we get:
|
|
>>
|
|
>> - Graph line on text / non-css browsers
|
|
>> - No percentage complete text on the same line as the graph line
|
|
>> - Deprecated HTML
|
|
>>
|
|
>> If we use `div` we get:
|
|
>>
|
|
>> - Need to clean up after HTMLScrubber (which is not hard - already implemented)
|
|
>> - Get the percentage written as text on text / non-css browsers
|
|
>> - Get the percentage on the same line as the graph in css browsers
|
|
>>
|
|
>> I'm strongly in favour of having the percentage text label on the graph, and on
|
|
>> text based browsers I think having the text label is enough -- the lack of the line
|
|
>> in that case doesn't bother me.
|
|
>> So, given the choice between the two suggested techniques, I'd take the second and
|
|
>> stay with div... unless you know how to get text next to (or within) an `<hr>` tag. -- [[Will]]

Default CSS styles for the plugin can be like below:
|
|
|
|
div.progress {
|
|
border: 1px solid #ddd;
|
|
/* border: 2px solid #ddd; */
|
|
width: 200px;
|
|
background: #fff;
|
|
padding: 2px;
|
|
/* padding: 0px; */
|
|
border: 2px solid #aaa;
|
|
background: #eee;
|
|
}
|
|
div.progress-done {
|
|
height: 14px;
|
|
background: #ff6600;
|
|
font-size: 12px;
|
|
text-align: center;
|
|
vertical-align: middle;
|
|
}
|
|
|
|
You can use alternative, commented CSS code for `div.progress` if you dislike
|
|
padding around done strip.

Any comments? --[[Paweł|ptecza]]

|
|
|
>> Below is the CSS I've been using -- [[Will]]
|
|
|
|
div.progress {
|
|
margin-top: 1ex;
|
|
margin-bottom: 1ex;
|
|
border: 1px solid #888;
|
|
width: 400px;
|
|
background: #eee;
|
|
color: black !important;
|
|
padding: 1px;
|
|
}
|
|
div.progress-done {
|
|
background: #ea6 !important;
|
|
color: black !important;
|
|
text-align: center;
|
|
padding: 1px;
|
|
}
|
|
|
|
> This looks like a nice idea. If I could add one further suggestion: Allow your

|
|
|
|
\[[!progress totalpages="bugs/* and backlink(milestoneB)" donepages="bugs/* and backlink(milestoneB) and !link(bugs/done)"]]
|
|
|
|

|
|
|
>> Thanks a lot for your comment, Will! It seems very interesting for me.
|
|
>> I need to think more about improving that plugin. --[[Paweł|ptecza]]
|
|
|
|
>> Attached is a [[patch]] (well, source) for this. You also need to add the proposed CSS above to `style.css`.
|
|
>> At the moment this plugin interacts poorly with the [[plugins/htmlscrubber]] plugin.
|
|
>> HTMLScrubber plugin removes the `style` attribute from the `progress-done` `div` tag, and so it defaults
|
|
>> to a width of 100%. -- [[Will]]
|
|
|
|
>>> Thank you for the code! I know how to fix that problem, because I had
|
|
>>> the same issue while writing [[todo/color_plugin]] :) --[[Paweł|ptecza]]
|
|
|
|
>>>> Ahh - good idea. Patch updated to work with HTMLScrubber. --[[Will]]
