While creating this variable in stata14 I've got an error (198)
this is the variable that I want to generate:
g ncskew =(-(([_n])*([_n-1])^(1.5)*(sum(returns^3))))///
/(([_n-1])*([_n-2])*(sum(returns^2)^(1.5))
It is quite a puzzle but I think that the brackets are well placed.
Any help or advice would be appreciated.
The problem that jumps out at my eye is that the /// at the end of the first line is not preceded by any whitespace. That is a syntax error.
The other problem is that you have 13 opening parentheses ( and just 12 closing parentheses ). Is this your actual code or a mis-typed copy?
Whether that are the only problems with your code, I cannot say. If that is your actual code, fix that first and see what happens.

I have the following segment of comment in my code file (the last line is intentionally missing the slash characters - that the error):
// * Cube Back Text from Méi guī
// 一颗 心 怕 摔倒 打破
//"yī kē xīn pà shuāi dǎo dǎ pò"
// "It's the heart afraid of breaking"
// 不敢 起舞 欢 歌
// "bù gǎn qǐwǔ huāngē"
// "that never learns to dance."
不敢起舞欢歌 (dance)
But the red error dot appears on the second character of the second line (second slash of the line "// * Cube Back Text from Méi guī".
Stranger, if I remove various quotes in the comment, the character that is hilited changes.
I assume this has something to do with a recursive structure somewhere in the parser that is continuing to parse the quotes inside the comment itself and ultimately figures out where to signal the error.
I suppose this is a bug ("semi-bug") that I should post to the GitHub list - to completely ignore anything past the second slash on a commented line, or some other change so that the error tag shows up on the line where the error actually is?
As it is, I futzed around about 10 minutes wondering if OpenSCAD just didn't like files longer than 575 lines.
I get the same problem when I try your example or modify it slightly but it worked perfectly when I replaced everything with random Latin characters so I think the bug has a lot to do with the Chinese ideographs you used.
In any case, I only copied the small sample you gave so it probably have nothing to do with the length of the file.
Maybe i'm missing something, but does anyone know how the debugging line numbering works in BigQuery?
I get an error like this:
Failed to save view. 2.196 - 2.226: Ambiguous column name eventcode.
and I'm not sure what the address 2.196-2.226 means. Specifically, what does the decimal signify? The second line of my query is very short (just SELECT *), so I don't think the numbers after the decimal indicate a character range?
Anyway -- I can't find any info for it in the docs, so any help here would be great
Line counting is most like shifted by 1 so it is actually line number #1 (not #2)
196 - 226 points to char range on that line with piece of code that introduces ambiquity - just the second piece (that has already existing aliac or column name for it)
Somehow for some first lines line numbering is incremented by 1 - it can be a bug on BQ UI side.
Btw, I noticed same strange behaviour in CodeMirror BQ UI is using, so it can be CodeMirror's bug too
I know there are a lot of resources with regex for it. But I could not find the one I want.
My problem is:
I want to remove one line comments (//) from obj-c sources, but I don't want to break the code in it. For instance, with this regex: #"//.*" I can remove all comments, but it also corrupts string literal:
#"bsdv//sdfsdf"
I played with non-capturing parentheses (?:(\"*\")*+), but without success.
Also I found this expression for Python:
r'(\".*?\"|\'.*?\')|(/\*.*?\*/|//[^\r\n]*$)'
It should cover my case, but I've not figure out how to make it work with obj-c.
Please, help me to build proper regex.
UPDATE: Yeah, that's a tough one, I know there're a lot of caveats, other than the one I described. I would appreciate if someone post regex that only fix my issue. Anyway, I gonna post my solution, without regex soon, I hope it will be helpful for anyone who struggling with such problem too.
Try this regex:
(?:^|.*;(?!.*")|#(?:define|endif|ifn?def|import|undef|...).*)\s*(//[^\r\n]+$)

Description
Discussion
Besides all the warnings expressed in the comments, I assume that a single line can appear in two distinct cases:
Case 1: Alone on its line preceded or not by blank chars
Case 2: Not Alone on its line preceded or not by blank chars, and other chars.
In the first case, we match the beginning of the line (^ with /m flag). Then we search zero or more blank chars (\s*) and finally the single line comment: //[$\r\n]+$.
In the second case, if there are other chars on the line, they form statements. Any statement is ended by a semicolon ;. So we search the last statement and its corresponding semicolon .*;(?!.*"). Then we search the single line comment. Those other chars can be also preprocessor statements. In this case, they are introduced by a sharp #.
One important keypoint is that I assume the code passed to the regex is a code that compiles.
There is more
Don't forget also to add some other pre-processor directives that may apply in your case. Check this SO answer: https://stackoverflow.com/a/18014883/363573
I'm using IDEA 13.0.1. A unit test is failing because of some line separator stuff. But when I try to compare the two results, IDEA says "Contents have differences only in line separators".
And I can't find a setting where I can say show me these differences. Is there one?
I ran into the same issue, I couldn't find a way to show the difference by clicking show differences, but if you put a break point and look at the strings, they have the line separator written out. For me one string had \n and one had \r\n. \r is also a possible line separator.
I ran into the same problem recently. I found a workaround for it, is not that pretty but did the job:
yourString.replaceAll("\n", "").replaceAll("\r", "");
The key is in what #user1633977 said.
To solve this problem, always use System.lineSeparator() to create your separators. That way they will always be the same and will be OS-independant.
(Remember that different OS can use different symbols as line separators).
I've made some function that generates an email template. Code it generates is pure HTML with CSS. Problem is compiler does this odd error and highlights each time '#' sign appears which is needed to define colors in CSS. I did try to change '#' to '/pound/' and then string.Replace() on RETURN but no luck. I'm more into C# so there i can escape special characters by using '\' before them but something f$#$ed up there... Once i remove '#' all back to normal and compiles well.
Any guesses ?
btw, i'm using StringBuilder to generate lines of code with sb.Append().
ie.
sb.Append("<div style=""color:#333"">some text</div>")
I think it's a bug,
to reproduce it I used VB.NET 2 (VS 2005), I wrote your instruction:
sb.Append("<div style=""color:#333"">some text</div>")
no problem,
I added some extra " to have the error message you got,
I then fixed everything, all errors disappeared except yours.
Solution: Delete that line, error disappeared, ctrl-z (undo) --> all ok!
I was receiving this same exact error and was able to simply copy the line, delete the line out, re-add a new line, and paste.
