formatting

问题 I have this code which is producing a timestamp and then parsing. DateTimeFormatter formatter = DateTimeFormatter .ofPattern("yyyyMMdd kk:HH:ss.SSSZ") .withLocale(Locale.getDefault()) .withZone(ZoneId.systemDefault()); Instant now = Instant.now(); String formatted = formatter.format(now); Instant parsed = formatter.parse(formatted, Instant::from); When it runs, the last line produces an exception: java.time.format.DateTimeParseException: Text '20180123 12:12:45.648-0500' could not be parsed:

问题 This seems weird. Java 8 is formatting the output differently depending on whether the millis is zero. How do you force Java 8 (1.8.0_20) to always spit out the millis regardless of if they're zero or not? public static void main(String[] args) { TemporalAccessor zeroedMillis = DateTimeFormatter.ISO_OFFSET_DATE_TIME.parse("2015-07-14T20:50:00.000Z"); TemporalAccessor hasMillis = DateTimeFormatter.ISO_OFFSET_DATE_TIME.parse("2015-07-14T20:50:00.333Z"); System.out.println(DateTimeFormatter.ISO

问题 I am trying to separate non-numbers from numbers in a Python string. Numbers can include floats. Examples Original String Desired String '4x5x6' '4 x 5 x 6' '7.2volt' '7.2 volt' '60BTU' '60 BTU' '20v' '20 v' '4*5' '4 * 5' '24in' '24 in' Here is a very good thread on how to achieve just that in PHP: Regex: Add space if letter is adjacent to a number I would like to manipulate the strings above in Python. Following piece of code works in the first example, but not in the others: new_element = [

问题 I have the following line in Powershell to output an array of data. The problem I am having is that Name,Title,Department do not go into columns. Instead I get a single column with each row in a single cell with tabs between. $outList | Format-Table Name,Title,Department -auto >c:\Scripts\test2.csv How can I output into columns? 回答1: You should be using the Export-Csv cmdlet instead. $outList | Export-Csv -path c:\scripts\test.csv -NoTypeInformation If you need only selected fields, pipe it

问题 I am trying to set a range of cells between bold cells. Here is what I have so far: With Worksheets("FC01.RPT") .Cells(.Rows.Count, 1).End(xlUp).Offset(2) = "Individual Rate Guest" Instead of using "Individual Rate Guest", how can I write it so that it will look for a bold format? Thanks! 回答1: This is how you would find the first two bold cells (offset to create a range between) in Column E of your worksheet regardless of content. You can replace the * with text if you wanted bold text of a

问题 I wanted to imitate Python's rjust , ljust , and center functions using the format! macro, but I was only able to work out a solution where you can pass in the string and the width. If you want to pass in the fill-argument it doesn't work. The documentation tells me that it is possible to provide variables to format! and for the width argument it works just fine. When I try to use a variable for fill, the compiler does not recognize the pattern. Just the width as a variable works: fn rjust

问题 Which formatter VCode uses? I read somewhere VC uses jsbeautifier so I tried adding a compatible ignore comment to my .ejs template, but to no avail. 回答1: As far as I know, there is no way to do this without an extension. However, you have full control of the formatting if you use this extension. It also uses js-beautify, but it adds configuration. As specified in the js-beautify docs, the "preserve" directive only works in javascript sections. I have tested this in the script tag of an ejs
