Does Realm models actually require getters and setters? : <p>I cannot find it clearly documented anywhere if getters and setters are actually required for fields in a Realm Model. For example, the documentation at <a href="https://realm.io/docs/java/latest/api/io/realm/RealmObject.html" rel="noreferrer">https://realm.io/docs/java/latest/api/io/realm/RealmObject.html</a> says</p>
<blockquote>
<p>The only restriction a RealmObject has is that fields are not allowed
to be final, transient' or volatile. Any method as well as public
fields are allowed. When providing custom constructors, a public
constructor with no arguments must be declared and be empty.</p>
<p>Fields annotated with Ignore don't have these restrictions and don't
require either a getter or setter.</p>
</blockquote>
<p>Which seems to hint that it is required with getters and setters for non-ignored fields. Yet, the documentation at <a href="https://realm.io/docs/java/latest/#customizing-objects" rel="noreferrer">https://realm.io/docs/java/latest/#customizing-objects</a> says</p>
<blockquote>
<p>It is possible to use RealmObjects almost like POJOs. Extending from
RealmObject, you can let the fields be public, and use simple
assignments instead of setters and getter.</p>
</blockquote>
<p>and then show the code for a Realm Model that does not have any getters and setters and instead have public fields we should use. Really? I thought Realm didn't even store any values in the actual fields, so reading and writing from them is probably a bad idea? I mean their debugging docs <a href="https://realm.io/docs/java/latest/#debugging" rel="noreferrer">https://realm.io/docs/java/latest/#debugging</a> state:</p>
<blockquote>
<p>Unfortunately these values are wrong because the field values are not
used. Realm creates a proxy object behind the scenes and overrides the
getters and setters in order to access the persisted data in the Realm</p>
</blockquote>
<p>So could someone please enlighten me? Can I skip getters and setters and just stick with public fields? Is there any thorough docs on this?</p>

Matplotlib canvas as numpy array artefacts : <p>I want to convert a matplotlib figure into a numpy array. I have been able to do this by accessing the contents of the renderer directly. However, when I call imshow on the numpy array it has what looks like aliasing artefacts along the edges which aren't present in the original figure.</p>
<p>I've tried playing around with various parameters but can't figure out how to fix the artefacts from imshow. The differences in the images remain if I save the figures to an image file.</p>
<p>Note that what I want to achieve is a way to confirm that the content of the array is the same as the figure I viewed before. I think probably these artefacts are not present in the numpy array but are created during the imshow call. Perhaps approriate configuration of imshow can resolve the problem.</p>
<pre><code>import matplotlib.pyplot as plt
import numpy as np
from matplotlib.patches import Rectangle
import math
fig = plt.figure(frameon=False)
ax = plt.gca()
ax.add_patch(Rectangle((0,0), 1, 1, angle=45, color="red"))
ax.set_xlim(-2,2)
ax.set_ylim(-2,2)
ax.set_aspect(1)
plt.axis("off")
fig.canvas.draw()
plt.savefig("rec1.png")
plt.show()
X = np.array(fig.canvas.renderer._renderer)
fig = plt.figure(frameon=False)
ax = plt.gca()
plt.axis("off")
plt.imshow(X)
plt.savefig("rec2.png")

Symfony 4 | Custom configuration file : I have been searching for a little while but I cannot find anything useful (or at least I think so).
My goal is to add to a new symfony 4.4 project an extra config file to define some behavior of the system, it could be anything, like, pancakes.yaml:
```yaml
pancakes:
enablePancakes: false
```
I wish to know how can I load that config file, find a way to read its parameters and values to change some custom behavior the system might have but honestly I think I'm not smart enough to undestand what the documentation says.
For now it could be anything, like printing the config file values, idk, for now I only need to know how to load it.
Any tip or help would be a great help for me, I'm kinda lost here

How to properly capture user's keystrokes in C#, i.e. respecting SHIFT key and differentiating between upper/lower-case characters? : I have written the following C# program to capture the user's keystrokes.
It works perfectly, except that all keys are logged as lower-case without taking the SHIFT key into account (see below).
I have read all of the Win32 API's documentation. Still I much be missing something.
How can I correct this program to log keystrokes properly?
If I enter `HelloWorld!!!`, the following keys are output in log.txt:
h
e
l
l
o
w
o
r
l
d
1
1
1
I.e., it does not consider SHIFT, which is the purpose of `GetKeyboardState()`?

The number of registers in CUDA CC 5.0? : I have a GeForce GTX 745 (CC 5.0).
The deviceQuery command shows that the total number of registers available per block is 65536 (65536 * 4 / 1024 = 256KB)
I wrote a kernel that uses an array of size 10K and the kernel is invoked as following.
I tried two ways to allocated the array:
// using registers
fun1() {
short *arr = new short[100*100]; // 100*100*sizeof(short)=256K / per thread
....
delete[] arr;
}
fun1<<<4, 64>>>();
// using global memory
fun2(short *d_arr) {
...
}
fun2<<<4, 64>>>(d_arr);
I can get the correct result in both manner.
The first one which uses registers runs much faster.
But when invoking the kernel using 6 blocks i got the wrong answer.
fun1<<<6, 64>>>();
Now i'm wondering actually how many of registers can i use? And how is it related to the number of blocks ?

Is there an API to make use of the Windows Speech Recognition's MouseGrid feature? : <p>I'm hoping to use Microsoft's built in Mouse Grid feature. The feature is typically used via the Windows Speech Recognition feature to systematically narrow down where to click the screen via your voice. </p>

Browser Form Behavior : Normally I use JSON API and SPA for when I make web apps, but I am trying to learn how to use the more simple method server-side template-ing and default form behavior.
Right now I am doing something very similar to what is seen [here][1]. The only difference is that i changed the `action` to `"/"` in the form for simplicity and handle the GET and POST from the same Handler (filtering by method type).
The initial web page renders fine, the data gets sent correctly in a POST, I answer the POST with a just a 200 but then my webpage goes blank.
How do i tell the browser to keep or rerender the original page? Do i need to send an HTML response to the POST? Something other than a 200?

int vol()

}
}
Hey guys I had created the following programme in my java tutorial. The problem is that i am not able to compute the volume of the box which has the double datatype.
The programme result shows the following:
volume is0.0
volume is0.0
volume is192
volume is192
Secondly i have a doubt in the java concept Method overloading, as i know that in method overloading we can use the same method name with different parameters but as i created the volume method, i had to modify the name of the methods(volume,vol) so as to overload the volume method and get the answer. why is it like that
Eagerly waiting for your reply guys as i am just new to the java programming language. i would a;so request you to paste the corrected code while answering.

SVGs in C#, draw multiple complex rectangles. : I'm creating a gannt chart to show hundreds of calendars for individual instances of orders, currently using an algorthim to draw lines and rectangles to create a grid, the problem is I'm the bitmaps are becoming far to large to draw, taking up ram, I've tried multiple different methods including drawing the bitmaps at half size and scaling them up (comes out horribly fuzzy) and still to large.
I want to be able to draw SVGs as I figure for something that draws large simple shapes should reduce the size dramatically compared to bitmaps.
the problem is I cant find anything on msdn that includes any sort of c# library for drawing svgs and I dont want to use external code.
Do I need to create It in XAML or is there a library similar to how bitmaps are drawn ?
[current bitmap version, either going out of bounds on the max size or just freezing because system is out of memeory][1]

Python: how to rewrite a list in a different style? : I am generating most common items from a list using this code:
content_count = [item for item in content_S if item[:1].isupper()]
content_E = Counter(content_count)
E = content_E.most_common(3)
the code generate a list like this:
E = [('item1', 8), ('item2', 6), ('item3', 5)]
Is there a way to convert the list E into something like this:
S = ['item1', 'item2', 'item3']
Searched for an answer here but no luck.

Is it possible to create product keys for my electron application? : <p>I want to build a desktop application and be able to publish product keys or serial numbers.Before the user can use the application he will be requested to enter the product key/serial number.</p>
<p>Similar to Microsoft Office when they provide keys like XXXX-XXXX-XXXX-XXXX</p>
<p>The idea I have is to sell the app based on licenses and providing product key for every device seems more professional than accounts (usernames and passwords).</p>
<p>so my questions are:</p>
<p>1) Is it possible to accomplish this with <code>electron</code>?</p>
<p>2) Can you advice me wether I should go for serial numbers (if it is doable) or accounts? or are there better options?</p>
<p>3) if you answered the second question. Please state why?</p>

Java: I have implemented 3 Search Algorithms. How I store these algorithms in a list (as method calls) and iterate over them in main? : **Briefing:**
I have implemented three search algorithms to break a lock. A lock can be broken by the actions shaking, pulling, pulling, or poking. These are 4 methods can be applied to the given lock. This lock has a length anywhere from 1 to 16, meaning that if the length was 16, 16 back to back actions in the correct order will need to be done. For example, a length two lock that can be unlocked by pulling and then poking will need to be pulled and then poked. The data structure devised to solve this is a tree where each parent has 4 children that correspond to actions. These search algorithms climb the tree in many ways to find the correct solution to break a given lock.
**Set-up of Solution & Problem:**
I have one class called *Tree* that has 3 Search algorithms: Breadth-First, Depth-Limited, and Iterative-Deepening Search. In this same class, I have 2 helper methods to help each algorithm break a lock combination (check, which checks if the sequence of actions up to the child being viewed is a solution, and depth, which determines the depth of a given child). I also have a Node class that is used by Tree to create the root and subsequent children. **Now,** I want to store each algorithm in an array, so that I can iterate over each algorithm, and collect data for each algorithm from a main function. I have looked a little into the *Command Pattern regarding Polymorphism*. It seems that it might work, but I am confused on how I would have to organize my current solution to adapt. Perhaps there is a better solution than the Command Pattern. I can create a main in the Tree and simply call each algorithm there, but that seems a bit "sloppy" to me. Any suggestions?

How can I store looped data into an array in java : Firstly I am a beginner in java script. I want to store all the looped data into the Course_Code and Grade arrays. everything works except that only the last entered value is store. what must i do to save all the data in the array.
<script>
const MIN = 999;
const MAX = 10000;
const minLet = 64;
const maxLet = 91;
const GRADE_VALUE = 'parseInt(7)%parseInt(6)%parseInt(5)%parseInt(4)%parseInt(3)%parseFloat(1.5)';
var i;
var j;
var Grade = new Array();
var Course_Code = new Array();
while (willingnes != false)
{
var willingnes = confirm('Do you want to enter new Course Code? Click OK to continue or Cancel to stop?');
if(willingnes == true)
{
Course_Code = prompt('Enter your Course Code','AAA1000');
var Digits = parseInt(Course_Code.slice(-4)); // extract the last four digits from course code
while(Course_Code.charCodeAt(0)<minLet || Course_Code.charCodeAt(0)>maxLet || Course_Code.charCodeAt(1)<minLet || Course_Code.charCodeAt(1)>maxLet ||Course_Code.charCodeAt(2)<minLet || Course_Code.charCodeAt(2)>maxLet || isNaN(Digits) || Digits<MIN || Digits>MAX) {
alert('Your input was invalid');
Course_Code = prompt('Enter your Course Code','AAA1000');
}
Grade = prompt('Input a valid Course grade:');
while(GRADE_VALUE.indexOf(Grade)<0){
alert('Invalid Course value.');
Grade = prompt('Re-enter valid course grade:');
}
}
}
alert(Course_Code);
alert(Grade);
</script>

line brake i #each#command : I have a html file that gets data from an .js file with #each command like this:
{{#each ssarr ../Maxss this}}
<td>{{this}}</td>
{{/each}}
that output the data in a long line.
Is it in some way possible to make a linebrake after 10 values so the row does not be so long?

Couldn't understand this SWIFT Fucntion : <p>Hope you are doing well. Would anyone please explain this code to me? I am still not getting how we got 120 here. When the parameters were passed to the function, where was it saved? How did it determine max and min before calculating? </p>
<p>Would be really appreciated if anyone could explain it for me please..</p>

How to test component callback invoked by child component callback in React with Enzyme? : <p>Say I have the following application:</p>
<pre><code>class Child extends React.Component {
render() {
return <button onClick={this.handleChildOnClick}>{this.props.children}</button>;
}
handleChildOnClick() {
this.props.onChildClick('foo');
}
}
class Parent extends React.Component {
render() {
return <Child onChildClick={this.handleParentOnClick}>click me</Child>;
}
handleParentOnClick(text) {
this.props.onParentClick(12345);
}
}
class App extends React.Component {
render() {
return <Parent onParentClick={(num) => console.log(num)} />;
}
}
</code></pre>
<p>I'm having a hard time figuring out the proper way to test the <code>Parent</code> component. The <code>Child</code> and <code>App</code> one are not a problem, but the <code>Parent</code>...</p>
<p>I mean, how do I test that a click on the <code>Child</code> component is going to invoke the <code>Parent</code> click callback without:</p>
<ol>
<li>...rendering <code>Child</code>. <code>Parent</code> should be tested in isolation as a shallow render. <code>Child</code> will also be tested in isolation and if I do a mount render, I'm basically testing the click callback on the <code>Child</code> twice.</li>
<li>...directly invoking <code>handleParentOnClick</code> on the <code>Parent</code> instance. I shouldn't depend on the exact implementation of <code>Parent</code> for this. If I change the name of the callback function, the test will break and it could very well be a false positive.</li>
</ol>
<p>Is there a third option?</p>

Is it possible to alias an import? : <p>In c# when pulling in a library that has a lot of name collisions with existing code, there's a way to alias the import so you don't need to fully clarify the namespace for each use. eg:</p>
<pre><code>using MyCompany.MyLibrary.Model as MMM
</code></pre>
<p>then you could do</p>
<pre><code>MMM.MyObject
</code></pre>
<p>instead of</p>
<pre><code>MyCompany.MyLibrary.Model.MyObject
</code></pre>
<p>With the recent update to swift 3.0, I've found some of my model objects are now colliding with the <code>Foundation</code> types, and I've been forced to prefix things that used to have an <code>NS</code> prefix in the class name with <code>Foundation.classname</code>. It would be great if I could type alias the import of my model library much like the c# example given above. Is this possible in swift 3.0? If not is there another strategy to avoid name collisions that would result in having to write the framework name in front of each type? I'm considering going back to prefixing my class names like we did in obj-c, but I'm trying to explore my options before I do that.</p>

'n' variable in rust loop undeclared? : I don't understand where this 'n' variable in the below code comes from or what exactly it is, the author says it reads 20 bytes at a time bytes at a time, where is this coming from? My real problem is figuring out how to read from a rust TcpStream, but I think I understand that part and would just like to know where 'n' comes from.
I am trying to implement an HTTP client (sorta) in Rust as my one of my first projects and I'm trying to follow this code:
```rust
fn handle_client(mut stream: TcpStream) {
// read 20 bytes at a time from stream echoing back to stream
loop {
let mut read = [0; 1028];
match stream.read(&mut read) {
Ok(n) => {
if n == 0 {
// connection was closed
break;
}
stream.write(&read[0..n]).unwrap();
}
Err(err) => {
panic!(err);
}
}
}
}
```
I haven't really tried anything yet because I want to understand before I do.

Vimeo video stops playing on Android 6 devices : <p>I'm trying to play video's from Vimeo in my app. The problem is that on Android 6 devices the video stops playing after a certain time. On devices with a lower API everything plays fine.</p>
<ul>
<li>The time depends on the quality. For the video of the provided url's below plays a certain minutes (1 to 3). How lower the video quality how longer it keeps playing.</li>
<li>After 1 to 3 minutes the mediaplayer throws an ProtocolException. The app does not crash on this but the video freezes when the buffered video piece is played. <code>[MediaHTTPConnection] readAt 25182208 / 32768 => java.net.ProtocolException: unexpected end of stream and shows this in de log</code></li>
<li>After the exception the video plays 30 seconds (buffered), then the application outputs this <code>[MediaPlayer] error (1, -1004)</code></li>
</ul>
<p>We're emailing for weeks now with Vimeo Support but they can't provide a solution or a possible cause. Now after weeks of mailing the support desk says that they're not supporting Android, but we've tried their suggestions:</p>
<ul>
<li>Use the redirected and unredirected url's</li>
</ul>

<ul>
<li><p>Use a video view instead of a mediaplayer </p></li>
<li><p>We've tried a native Android and a Xamarin Android implementation</p></li>
<li><p>Try to download the file => this works but we want to stream because some video's are longer then 30 minutes (>100mb). Uncomment the code in the onCreate in the DownLoadActivity to test downloading.</p></li>
</ul>
<p>In the browser everything works fine. </p>

Filling a progressbar via a variable : <p>I am using four ProgressBars in my AndroidApp.
First of all I want them all to be empty, and when I update a Variable, I want one of the ProgressBars to get filled a bit. But only up to a "goal" that I want to set in beforehand. For example as soon as the Variable hits 1000, the ProgressBar should be filled and a message should pop up or something like that, when the variable is 500, it should be halfway filled and so on.</p>
<p>These are my problems, I think they might all be solved by knowing how to bind a ProgressBar to a variable? If so, please tell me how I can achieve that, else, please tell me how I can still get my plan done. THANK YOU!</p>

Why is self a required parameter for a method? : <p>Let's say that I have a tiny code like this:</p>
<pre><code>#!/usr/bin/env python3
class Dog():
def __init__(self, name, age):
self.name = name
self.age = age
def sit(self):
print(self.name + " is now sitting.")
my_dog = Dog('willie',6)
my_dog.sit()
</code></pre>
<p>As I understand, the line <code>my_dog = Dog('willie',6)</code> creates an instance named <code>my_dog</code>. It calls the <code>__init__</code> function, converts it internally to <code>Dog.__init__(my_dog, willie, 6)</code> and sets the <code>my_dog.name</code> and <code>my_dog.age</code> variables to <code>willie</code> and <code>6</code>? Now when the <code>my_dog.sit()</code> is executed, then why does the method <code>sit()</code> require a <code>self</code> as a parameter? Is it because if there is another instance of the same class(for example, <code>your_dog</code>), then it knows to use <code>your_dog.name</code> instead of <code>my_dog.name</code>?</p>

Overload the + operator to add an object with int : <p>I have just learned operator overloading and I am having trouble overloading the '+' operator to add an object with int. I am also not sure with how to overload the '<<' to output an object. </p>
<p>Any advice or help would be greatly appreciated.</p>
<pre><code>#include<iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
class CLOCK
{
public:
int h, m, s;
CLOCK()
{
h = 0;
m = 0;
s = 0;
}
CLOCK(int hour, int minute, int second)
{
hour = h;
minute = m;
second = s;
}
CLOCK operator+(int time)
{
CLOCK c(*this);
c.m += time;
return c;
}
CLOCK operator++(int)
{
CLOCK c(h,m,s);
h++;
return c;
}
friend ostream &operator<<(ostream &output, const CLOCK &c)
{
output << c.h << c.m << c.s << endl;
return output;
}
};
int main()
{
CLOCK c(10, 10, 10);
cout << c << endl; // should display 101010
c = c + 10; // should display 10 minutes to my clock

Android signature verification : <p>I have got lot of doubts to be cleared in the case of Android signature verification and its vulnerability. </p>
<p>Once we generate apk for an application we can unpack the apk and edit resource files using apktool. As we repack the edited apk back it loses its signature. I can resign the unsigned apk using the jarsigner with my own private key that i used while generating the apk. I found an application named zipsigner in playstore which can be used to sign such kind of unsigned apk. </p>
<p>So when this zipsigner signs the unsigned apk, whether the apk is signed with my same private key or with a different key? Because my META-INF folder still holds the XXX.SF and XXX.RSA files which holds the information of my private key. If it is with my same private key then the new apk will be an upgrade for my application or if it is a different key i will be having two different applications with same name. </p>
<p>From the above situations there are possibilities that malware could be included in my apk while repacking. There seems to be a loophole in Android's signature verification mechanism where the message digest of the files inside the META-INF folder are not included in the MANIFEST.MF as well as in the XXX.SF file. This creates a possibility for anyone to include malware codes inside these folders, repack the apk and resign it with the zipsigner application. </p>
<p>I was searching for a solution where i can prevent files being added into the META-INF folder and i found one from the below blog. But I'm unable to get the point of the solution. This looks like more of a research topic so there is not much information available in the internet. Can someone try and figure out the solution specified in the blog. The blog link is specified below the question. </p>

Why is adding methods to a type different than adding a sub or an operator in perl6? : <p>Making subs/procedures available for reuse is one core function of modules, and I would argue that it is the fundamental way how a language can be composable and therefore efficient with programmer time: </p>
<p>if you create a type in your module, I can create my own module that adds a sub that operates on your type. I do not have to extend your module to do that.</p>
<pre><code># your module
class Foo {
has $.id;
has $.name;
}
# my module
sub foo-str(Foo:D $f) is export {
return "[{$f.id}-{$f.name}]"
}
# someone else using yours and mine together for profit
my $f = Foo.new(:id(1234), :name("brclge"));
say foo-str($f);
</code></pre>
<p>As seen in <a href="https://stackoverflow.com/questions/55814075/overloading-operators-for-a-class">Overloading operators for a class</a> this composability of modules works equally well for operators, which to me makes sense since operators are just some kinda syntactic sugar for subs anyway (in my head at least). Note that the definition of such an operator does not cause any surprising change of behavior of existing code, you need to import it into your code explicitly to get access to it, just like the sub above.</p>
<p>Given this, I find it very odd that we do not have a similar mechanism for methods, see e.g. the discussion at <a href="https://stackoverflow.com/questions/34504849/how-do-you-add-a-method-to-an-existing-class-in-perl-6">How do you add a method to an existing class in Perl 6?</a>, especially since perl6 is such a method-happy language. If I want to extend the usage of an existing type, I would want to do that in the same style as the original module was written in. If there is a .is-prime on Int, it must be possible for me to add a .is-semi-prime as well, right?</p>
<p>I read the discussion at the link above, but don't quite buy the "action at a distance" argument: how is that different from me exporting another multi sub from a module? for example the rust way of making this a lexical change (Trait + impl ... for) seems quite hygienic to me, and would be very much in line with the operator approach above.</p>
<p>More interesting (to me at least) than the technicalities is the question if language design: isn't the ability to provide new verbs (subs, operators, methods) for existing nouns (types) a core design goal for a language like perl6? If it is, why would it treat methods differently? And if it does treat them differently for a good reason, does that not mean we are using way to many non-composable methods as nouns where we should be using subs instead?</p>

Is it possible to spread a list inside a list in Kotlin? : <p>It is possible to do argument unpacking in Kotlin similar to how it is done in Python? E.g.</p>
<pre><code>>>> a = [1,2,3]
>>> b = [*a,4,5,6]
>>> b
[1, 2, 3, 4, 5, 6]
</code></pre>
<p>I know that it is possible in Kotlin as follows:</p>
<pre><code>>>> listOf(1, 2, 3, *listOf(4,5,6).toTypedArray())
[1, 2, 3, 4, 5, 6]
</code></pre>
<p>Feels like there is an easier way in Kotlin. Any ideas?</p>

"İ".toLowerCase() != "i" : <p>In Turkish, there's a letter <code>İ</code> which is the uppercase form of <code>i</code>. When I convert it to lowercase, I get a weird result. For example:</p>

<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var string_tr = "İ".toLowerCase();
var string_en = "i";
console.log( string_tr == string_en ); // false
console.log( string_tr.split("") ); // ["i", "̇"]
console.log( string_tr.charCodeAt(1) ); // 775
console.log( string_en.charCodeAt(0) ); // 105</code></pre>
</div>
</div>
</p>
<p><code>"İ".toLowerCase()</code> returns an extra character, and if I'm not mistaken, it's <a href="http://www.fileformat.info/info/unicode/char/0307/index.htm" rel="noreferrer">COMBINING DOT ABOVE (U+0307)</a>.</p>
<p>How do I get rid of this character?</p>
<p>I could just filter the string:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>var string_tr = "İ".toLowerCase();
string_tr = string_tr.split("").filter(function (item) {

console.log(string_tr.split(""));</code></pre>

</p>
<p>but am I handing this correctly? Is there a more preferable way? Furthermore, why does this extra character appear in the first place?</p>
<p>There's some inconsistency. For example, in Turkish, there a lowercase form of <code>I</code>: <code>ı</code>. How come the following comparison returns true</p>

white space control in jekyll - why does {%- ... -%} a la liquid not work? : <p>The <a href="https://help.shopify.com/themes/liquid/basics/whitespace" rel="noreferrer">liquid documentation</a> states that </p>
<blockquote>
<p>By including hyphens in your assign tag, you can strip the generated whitespace from the rendered template ... if you don't want any of your tags to output whitespace, as a general rule you can add hyphens to both sides of all your tags ({%- and -%}):</p>
</blockquote>
<p>When I try in jekyll</p>
<pre><code>{%- case key -%}
</code></pre>
<p>I get the error</p>
<pre><code>Error: Liquid syntax error (line 139): Tag '{%- case key -%}' was not
properly terminated with regexp: /\%\}/
</code></pre>
<p>There are many posts about excessive whitespace in the jekyll generated html, for example <a href="https://www.sylvaindurand.org/compressing-liquid-generated-html/" rel="noreferrer">Compressing Liquid generated code</a>.</p>
<p>They all complain about dilute HTML output and discuss plug-ins as solution.
My simple questions are:</p>
<ol>
<li>Why does <code>{%- ... -%}</code> not work in jekyll ?</li>
<li>Why behaves jekyll differently than the liquid documentation suggests</li>
</ol>
