I use litElement with vaadin and have next code
<vaadin-app-layout .drawerOpened='false'>
<vaadin-drawer-toggle slot="navbar" ></vaadin-drawer-toggle>
<vaadin-tabs selected="-100" slot="drawer" orientation="vertical" theme="minimal" style="margin: 0 auto; flex: 1;">
${this.renderTabsDependOnStatusAccess()}
</vaadin-tabs>
<div class="content" >
<div id="outlet"></div>
</div>
</vaadin-app-layout>
but my vaadin-drawer-toggle component is still open, how can I make it private by default and wats wrong with my example
I've not used this component, but I'll guess that in JS it's drawerOpened while in HTML it's drawer-opened. Also, boolean attributes are usually present or not, so instead of drawer-opened="false" you probably just remove it. Plain drawer-opened would be true.
If this HTML or in the LitElement render()? In the latter you may want to use ?drawer-opened="${this.isDrawerOpen}" and toggle a property this.isDrawerOpen

I need to add an icon near myLink in razor view,
in .html page i use ` Requête optimisée.
Now i have
#Html.ActionLink("Requete optimisée", "Index", "Requete")
Dont know where to add my icon .
I wouldn't use ActionLink and would do the following:
<a href="#Url.Action("Index","Requete")" class="my-link-class">Requete optimisée
<div class="my-icon"><img src="#Url.Content("~/icon.jpg")" alt="Icon Image" /></a>
More code but also more freedom and control over what is going on.
If you want show an icon just put a img tag before your link:
<img src="~/Content/Images/Image.png" />
#Html.ActionLink("Requete optimisée", "Index", "Requete")
And if you want to display image link then use this:
#Html.ActionImage("Requete optimisée", "Requete", "~/Content/Images/Image.png")

At my company we have a very complex build-system based on Ant. Understanding it took me a long time. I'm currently restructuring it and would also make it easier for new developers to win through it.
Is there any (good) documentation-generator that can generate a documentation based on build.xml-files and their includes?
You can write XSLT rules to convert it to HTML with the links or smth like this.
(Hmm, or much easier may be using CSS for build.xml)
i.e.
<target name="tar1" depends="tar2, tar3">
....
</target>
will come to
<div class="target">
<a name="tar1"><p class="name">tar1</p></a>
<div class="deps-list">
Depends on:
<ul>
<li>tar2</li>
<li>tar3</li>
</ul>
</div>
<div class="content">
Tasks:
<ul>
<li><p class="taskname">Copy</p><p class="taskargs">args...</p></li>
...
</ul>
</div>
</div>

I am trying to create a simple calculator application .
calculator.html.erb
<input type=text name="operand_one" value="0"></td>
<input type=text name="operand_two" value="0"></td>
.
.
.
<input type=text name="output" value="<% =#result %>"></td>
I am able to get the output correctly but the values of the first two text boxes changes to 0 , I need to know how to retain these values ..
You're hardcoding the value to "0" with this part of the code
value="0"
you could change the lines to
<input type=text name="operand_one" value="#value_one"></td> #etc...
and in your controller
#value_one = 0 unless X
but X depends on how your controller works - do you go to a new action to solve the problem in the calculator? if so you'll have to use the params hash.
Not related to the question, but why are you using text for your calculation fields? and are you hard coding that html or it's just the output?

hi i have a value like this in html.erb
<img src="<%= file.title, file_path(file) %>" alt=""/>
but when I placed the above code it throws an error
SyntaxError in Files#index
the error comes on file_path(file) section . Is there a way to accomplish this ? like declare a variable and assign it to something ?
Though I did not get whay you are trying to achieve but you can try to do it like this
<img src="<%= "#{file.title}, #{file_path(file)}" %>" alt=""/>
You should declare file (a better naming is #file) in the controller action which is associated with this view. There you can do whatever you want with your variable.

Just to help other developers, because there is no similar question on SO.
div class=(is_active? ? 'active' : 'inactive')
div class=('active' if is_active?)
See the examples below:
div class=(is_active? ? 'active' : 'inactive')
div class=('active' if is_active?)
The same approach can be used to assign dynamic values to other attributes.
I use array of classes and nil element if there is no need to include class in list, then compact array to remove nil elements and finally join all together.
div class=(["cday", "col-md-1", day.day == 1 ? "col-md-offset-#{day.cwday-1}" : nil].compact.join(' '))
If you have multiple conditions I am doing right now something like
div class=(('foo ' if is_foo?) + ('bar' if is_bar?))
Though I feel it to be a blemish if is_bar? return false and the generated HTML results in
<div class="foo "></div>
(the blemish is the blank character after the foo). If someone had a solution for that would be awesome.
