Is it possible to escape whole declaration?
This complies fine in less.js (I'm using less.app)
margin: e(" 0 10px");
But this throws an error:
e("margin: 0 10px");
I've tried putting 'margin' in a variable but without success.
Sorry that's not possible. A couple things though:
The official escape designation (according to lesscss.org is the tilde-quote, not the e() syntax, like so:
margin: ~"0 10px";
Second, the code you provided is not nearly complex enough to warrant a LESS CSS string literal. Please share the actual code that you are having trouble with. You may want to close this question and ask another one.
Third, remember that you can include a .css file - it will not be compiled, just dumped into the output. The syntax is identical to a standard CSS import:
#import "myfile.css";
After many attempts, I got this to compile and output in my less file.
font-family: e("'object-fit: contain;'");
This is a hack for IE object-fit (I got that idea from object-fit

I'm removing builder pattern on multiple places. Following example would help me with the task, but mainly I'd like to learn how to use live templates more.
Preexisting code:
Something s = s.builder
.a(...)
.b(bbb)
.build();
and I'd like to remove it to:
Something s = new Something();
s.setA(...);
s.setB(bbb);
part of it can be trivially done using intellij regex, pattern: \.(.*)$ and replacement .set\u$1. Well it could be improved, but lets keep it simple.
I can create surround live template using variable:
regularExpression(SELECTION, "\\.(.*)", "\\u$1")
but \\u will be evaluated as u.
question 1: is it possible to get into here somehow \u functionality?
but I might get around is differently, so why not try to use live temlate variable:
regularExpression(SELECTION, "\\.(.)(.*)", concat(capitalize($1), "$2"))
but this does not seem to work either. .abc is replaced to bc
question 2: why? How would correct template look like? And probably, if it worked, this would behave incorrectly for multiline input. How to make it working and also for multiline inputs?
sorry for questions, I didn't find any harder examples of live templates than trivial replacements.
No, there is no \u functionality in the regularExpression() Live Template macro. It is just a way to call String.replaceAll(), which doesn't support \u.
You can create a Live Template like this:
set$VAR$
And set the following expression for the $VAR$ variable:
capitalize(regularExpression(SELECTION, "\\.(.*)", "$1"))
When trying to filter by tag, there is a small popup:
I have been looking for logfmt around, but all I can find is key=value format.
My questions are:
Is there a way for something more sophisticated? (starts_with, not equal, contains, etc)
I am trying to filter by url using http.url="http://example.com?bla=bla&foo=bar". I am pretty sure the value exists because I am copy/pasting from my trace. I am getting no results. Do I need to escape characters or do something else for this to work?
I did some research around logfmt as well. Based on the documentation of the original implementation and in the Python implementation of the parser (and respective tests), I would say that it doesn't support anything more sophisticated (like starts_with, not equal, contains). And this is because the output of the parser is a simple dictionary (with no regex involved in the values).
As for the second question, using the same mentioned Python parser, I was able to double-check that your filter looks fine:
from logfmt import parse_line
parse_line('http.url="http://example.com?bla=bla&foo=bar"')
Output:
{'http.url': 'http://example.com?bla=bla&foo=bar'}
This makes me suspect of an issue on the Jaeger side, but this is as far as I could go.
I am currently working on a Java project, and I am finding IntelliJ Idea's code style system to be extreamly frustrating as it refuses to accept the settings that I want to give it. Specifically, I want spaces around various operators unless they're inside a for loop's header. For example, the following code should be output:
for(int x=0;x<10;++x){ // no spaces around operators when they're in a for loop's header
System.out.println(x);
}
int a = 10; //spaces around = when not in a for loop's header
int b = 50;
a = b;
if(a < b){ //an if statement is not a for loop's header
doSomething();
}
In essence, I want IntelliJ to make an exception to normal space rules when in the header of a for loop, removing these spaces. It looks absolutely disgusting to me to have what should be a dense construction filled with superfluous spaces, to the point that it is making me not want to use IntelliJ Idea at all, despite its numerous great features. THis, for example, severely diminishes the utility of its automatic refactoring ability because I need to manually go through and fix its formatting errors after every refactor.
When I look in the code style settings, the "around operators" checkboxes seem to have no mechanism for a different setting inside for loops:
How can I get IntelliJ Idea to format my code correctly?
I'm using a Velocity template to generate an e-mail. Within that e-mail, I want to create a mailto link that will look like this:
Link
I have this chunk of code that properly creates that link:
Link
That code works, but it's nearly impossible to read. I want to put some line breaks in there so that I'd have something more like this:
<a href="mailto:
#foreach(${person} in ${people})
${person.email}
#if($foreach.hasNext)
,
#end
#end
?subject=My%20Subject%20Line">Link</a>
I find that to be much easier to read, but Velocity will include all the whitespace into the output and causes the link that it produces to break.
Is there any way to format the code the way I want and tell Velocity to ignore all the whitespace throughout that segment?
Thanks!
A first option is to use comments:
<a href="mailto:#*
*##foreach(${person} in ${people})#*
*#${person.email}#*
*##if($foreach.hasNext)#*
*#,#*
*##end#*
*##end#*
*#?subject=My%20Subject%20Line">Link</a>
Another option is to add a pre-processing that will remove all indenting spaces and carriage returns.
Yet another is to do it as a post-processing.
The way to add this pre- or post- processing is dependent on the context in which you are using Velocity.
So I'm trying to make it so the I get all the text out of a css class.
For instance,
h1 {
font-weight: bold;
}
I need to get a string which will contain "font-weight: bold;"
I also need to make sure this doesn't get mixed up with other classes. Basically imagine that was in the middle of a huge css file. How would I get just that class.
(it is ok to ignore things such as h1.blah or variations of h1.)
This would be the RegEx to grab anything inside of a standard h1 declaration. It takes into account spacing and so forth. You probably want more finely-tuned results, but the question lacks the specificity necessary to address the problem further.
