Always discard result for a parser combinator
Tag : scala , By : leorick

should help you out In earlier versions of scala the discard method existed to throw away the results of a parser: , You can simply reference the extra parser result but not use it: otherParser ~ throwThisAway ~ anotherParser ^^ { case a ~ x ~ b => // eg.: SomeCaseClass(a,b)
otherParser ~ throwThisAway ~ anotherParser ^^ { case a ~ _ ~ b => ...

Haskell parsec: `many` combinator inside an `optional` combinator
Date : March 29 2020, 07:55 AM
this one helps. We can also state this slightly different: c in your parser may only succeed if it's followed by any token, which can be done with a single lookAhead: myParser = many (a <|> b <|> (c <* (lookAhead anyToken <?> "non C token"))) <* eof

When working with css child combinator on list i'm not getting the result I expected
Tag : html , By : Al Dimond

it should still fix some issue You forgot 2 lines in the html. After that, your style will work fine but it will also change the color of D, E and F because they are on the same level as H. <aside class="sitemap">
<ul class="pages">
<li>A</li>
<li>B</li>
<li>C
<ul>
<li>D</li>
<li class="featured">E</li>
<li>F</li>
</ul>
</li> <!-- add this line -->
<li>G</li>
<li> <!-- add this line -->
<ul>
<li>H
<ul>
<li class="featured">I</li>
<li>J</li>
</ul>
</li>
</ul>
</li>
</ul>
</aside>

CSS > combinator not getting result I expected
Date : March 29 2020, 07:55 AM
I wish did fix the issue. The > operator only selects the direct (first gen) children of the element. In the case of color, the child elements of that targeted element inherit that style rule: #outside>li {
color: green;
}
<ul id="outside">
<li>A</li>
<li>B</li>
<li>C</li>
<ul>
<li>D</li>
<li>E</li>
<li>F</li>
</ul>
<li>G</li>
</ul>
#three>#two {
color: green;
}
<div id="three">
three
<div id="two">
two
<header id="one">
one
<footer id="zero">
zero
</footer>
</header>
</div>
</div>
