I'm using Codekit to compile and process SCSS, and recently it was recommended to upgrade from Liblass to Dart, for future proofing.
This seems to be an easy switchover, however I do have one snippet of code that is throwing an error during compilation. I wonder if anyone might be able to assist with? The error is: Dart Sass failed with this error: Error: expected "$".
The code in question is intended to iterate over a number of nth-child() elements and incrementally apply a transition-delay to them, increasing by 150ms per item.
#for $i from 1 to 50 {
&:nth-child($i) { transition-delay: calc($i * 150ms); }
}
Thank you.
You need to interpolate the variable:
#for $i from 1 to 50 {
&:nth-child(#{$i}) { transition-delay: calc(#{$i} * 150ms); }
}

In my rails app, I get a syntax error somewhere in a huge js file that is presumably generated by webpacker. But it seems to be some sort of angular/material code. If I don't include material design, the error goes away, so it seems to be related to material design. This is the part that causes the syntax error:
function instantiateSupportedAnimationDriver() {
return !(function webpackMissingModule() { var e = new Error("Cannot find module '#angular/animations/browser'"); e.code = 'MODULE_NOT_FOUND'; throw e; }())() ? new !(function webpackMissingModule() { var e = new Error("Cannot find module '#angular/animations/browser'"); e.code = 'MODULE_NOT_FOUND'; throw e; }())() : new !(function webpackMissingModule() { var e = new Error("Cannot find module '#angular/animations/browser'"); e.code = 'MODULE_NOT_FOUND'; throw e; }())();
}
Note that telling me how to fix the syntax error doesn't help me. This code is not in my control and I wouldn't know how to effectively patch it. Besides, it's a frequently used piece of code, I doubt that it has a syntax error, probably something in plumbing is incorrect.
Some context: I probably don't get all the mechanics right. I am trying to make the combination Rails + Webpacker + Typescript + Angular + Material work. It's quite tricky, I find nothing useful on it on the web and I seem to be pretty much the first one to do it. I saw some suggestions to make an api-only rails app, but I don't like that...
I never really figured out why this caused a syntax error in a seemingly unrelated file, but I had some "unmet peer dependency" warnings and when I fixed them, this went away.
I'm trying to use the haskell-src-exts package to parse Haskell modules. Currently, I'm trying to parse the acme-io package's module, but I keep getting this error no matter what parse mode I try:
*** Exception: fromParseResult: Parse failed at [System/IO/Unsafe/Really/IMeanIt] (1:57): TemplateHaskell is not enabled
The module mentioned makes no references to TemplateHaskell, not in it's LANGUAGE pragma, nor is there a $ anywhere in the source file.
I'm wondering if my parse mode has something to do with it - here it is:
defaultParseMode { parseFilename = toFilePath m
, baseLanguage = Haskell2010
, extensions = []
, ignoreLanguagePragmas = True
, ignoreLinePragmas = True
, fixities = Nothing
}
I've also tried to replace the extensions field with knownExtensions from the parsing suite, without any luck.
This is a duplicate question of this answer - using the parseFile function fixed the issue. However, the reader should note that haskell-src-exts uses different parsing than GHC - I ran into another similar issue right after this, because haskell-src-exts can't handle multi-param contexts without -XMultiParamTypeClasses, yet GHC can, borking the parser if you're scraping Hackage. Hint may be a better option, can't say for sure though.
I've noticed that calling hh_client is not always returning correct result. For example: I have following pieces of code:
backend\ConvertMessage.hh:
<?hh // strict
namespace ApiBackend\ConvertMessage {
enum Status: int {
success = 0;
// ... error codes
};
// ... some other classes
};
other place in project:
throw new \SoapFault(
'Server',
\ApiBackend\ConvertMessage\Status::getNames()[$result->status]
);
Sometimes, after doing some changes in project I get following error message: Could not find static method getNames in type ApiBackend\ConvertMessage\Status (Typing[4090])
When I remove a semicolon after one of closing curly brackets, hh_client stops displaying error. But when I insert semicolon back on its place, typechecker still gives me No errors! message.
This is not the only file that causes this problem - it happens to all enums.
It seems to me that it is problem with some cache of either hh_client or hh_server.
Thanks in advance for helping me with solving this problem (and sorry if my english is not too good).
You are probably using an outdated version of HHVM. This problem sounds an awful lot like this race condition, which was fixed in HHVM 3.5.0 and newer (and was backported into the 3.3.3 LTS release). Notably, 3.4.x still had the bug.
What version of HHVM are you using?
I am using a REXML Ruby parser to parse an XML file. But on a 64 bit AIX box with 64 bit Ruby, I am getting the following error:
REXML::ParseException: #<REXML::ParseException: #<RegexpError: Stack overflow in
regexp matcher:
/^<((?>(?:[\w:][\-\w\d.]*:)?[\w:][\-\w\d.]*))\s*((?>\s+(?:[\w:][\-\w\d.]*:)?[\w:][\-\w\d.]*\s*=\s*(["']).*?\3)*)\s*(\/)?>/mu>
The call for the same is something like this:
REXML::Document.new(File.open(actual_file_name, "r"))
Does anyone have an idea regarding how to solve this issue?
I've had several issues for REXML, it doesn't seem to be the most mature library. Usually I use Nokogiri for Ruby XML parsing stuff, it should be faster and more stable than REXML. After installing it with sudo gem install nokogiri, you can use something like this to get a DOM instance:
doc = Nokogiri.XML(File.open(actual_file_name, 'rb'))
# => #<Nokogiri::XML::Document:0xf1de34 name="document" [...] >
The documentation on the official webpage is also much better than that of REXML, IMHO.
I almost immediately found the answer.
The first thing I did was to search in the ruby source code for the error being thrown.
I found that regex.h was responsible for this.
In regex.h, the code flow is something like this:
/* Maximum number of duplicates an interval can allow. */
#ifndef RE_DUP_MAX
#define RE_DUP_MAX ((1 << 15) - 1)
#endif
Now the problem here is RE_DUP_MAX. On AIX box, the same constant has been defined somewhere in /usr/include.
I searched for it and found in
/usr/include/NLregexp.h
/usr/include/sys/limits.h
/usr/include/unistd.h
I am not sure which of the three is being used(most probably NLregexp.h).
In these headers, the value of RE_DUP_MAX has been set to 255! So there is a cap placed on the number of repetitions of a regex!
In short, the reason is the compilation taking the system defined value than that we define in regex.h!
This also answers my question which i had asked recently:
Regex limit in ruby 64 bit aix compilation
I was not able to answer it immediately as i need to have min of 100 reputation :D :D

In a GSP file I write something like this:
${tgs.singleGameSheets.find{it.matchnumber==1}.awayPlayer.fullname()}
But I receive the following error:
org.codehaus.groovy.control.MultipleCompilationErrorsException:
startup failed:
C__STS_Projekte_TischtennisManager_grails_app_views_league__showGameSheet_gsp:
49:expecting '}', found ')' # line 49, column 134.
heets.find{it.matchnumber==1 })
The problem seems to be the double closure as I've found a bug report here.
Unfortunately the solution from the bugreport with the %= and % at the beginning and the end of the tag is not working for me.
Are there any other workarounds or solutions for this double closure problem?
I'm using Grails 1.3.7.
You may have to split this up in to two lines.
Try assigning the find results to a separate var first
<% def r = tgs.singleGameSheets.find{it.matchnumber==1} %>
${r*.awayPlayer.fullname()}
I would recommend firstly to do this sort of data processing in the controller and hand data that is as well prepared as possible down to the view.
If you are unable to do that, I would recommend trying to use parenthesis:
${tgs.singleGameSheets.find{it.matchnumber==1}.awayPlayer.fullname()}
becomes
${(tgs.singleGameSheets.find{it.matchnumber==1}.awayPlayer.fullname())}
That has worked for me on past occasions where I had to do ${(someCollection.findAll { someClause })}
