I got a couple of response from a json which includes curly braces such as ${title} or {title}
How can I replace these vaules with values I preselected?
For example:
jsonString = '{title}.2019.mkv'
jsonString2 = '${title}.2019.mkv'
How can I replace the field in those Strings with values I preselected like:
var title = 'Avengers'
Maybe I should just use regex or is there a better way?
In case you need to replace part of the string you can use
'{title}.2019.mkv'.replaceFirst('{title}', 'Avengers')

I have a messages in file like below and I am using com.univocity.parsers.csv.CsvParser to split the string based on delimiter(in this case its -)
1-bc-"name"-def-address
1-abc-"name-def-address
I create my CsvParser object like
private val settings = new CsvParserSettings()
settings.getFormat.setDelimiter('-')
settings.setIgnoreLeadingWhitespaces(true)
settings.setIgnoreTrailingWhitespaces(true)
settings.setReadInputOnSeparateThread(false)
settings.setNullValue("")
settings.setMaxCharsPerColumn(-1)
val parser = new CsvParser(settings)
and parse the input message like :
for (line <- Source.fromFile("path\\test.txt").getLines) {
println(parser.parseLine(line).toList)
}
and the output is:
List(1, bc, name, def, address)
List(1, abc, name-def-address)
If you see the output you can see that for 1st message the string was split properly however for second message it takes everything as a value after first double quote. Does anyone know why the behavior is like this and how can I get the desired output? I am reading every message as a string to it should simple treat a quote/double quote as a character.
Author of this library here. When the quote is found after your - delimiter, the parser will try to find a closing quote.
The easiest way around this is to make the parser simply ignore quotes with:
settings.getFormat().setQuote('\0');
Hope it helps.
How do I make scala ignore the quotes inside of a String?
e.g.
val line1 = "<row Id="85" PostTypeId="1""
I want <row Id="85" PostTypeId="1" to be considered as a single string. However scala outputs error thinking that "<row Id=" is a string and everything after it is not related
Thanks in advance
val line1 = """<row Id="85" PostTypeId="1""""
Note those triple quotes ("""blahblah""") - to parse the string without escaping.
I have Strings in the following structure:
cmd, addr, data, data, data, data, ……., \n
For example:
"write,A0001000,00000000, \n"
I have to know how many words the String has.
I know that I can go over the String and search for the number of commas, but is there more effective way to do it?
UVM provides a facility to do regexp matching using the DPI, in case you're already using that. Have a look at the functions in uvm_svcmd_dpi.svh
Verilab also provides svlib, a package containing string matching functions.
A simpler option would be to change the commas(,) to a space, then you can use $sscanf (or $fscanf to skip the intermediate string and read directly from a file), assuming each command has a maximum number of words.
int code; // returns the number of words read
string str,word[5];
code = $sscanf(str,"%s %s %s %s %s", word[0],word[1],word[2],word[3],word[4]);
You can use %h if you know a word is in hex and translate it directly to a numeric value instead of a string.
The first step is to define extremely clearly what a word actually is vis. what constitutes the start of a word and what constitutes the end of the word, once you understand this, if should become obvious how to parse the string correctly.
In Java StringTokenizer is the best way to find the count of words in a string.
String sampleString= "cmd addr data data data data...."
StringTokenizer st = new Tokenizer(sampleString);
st.countTokens();
Hope this will help you :)
In java you can use following code to count words in string
public class WordCounts{
public static void main(String []args){
String text="cmd, addr, data, data, data, data";
String trimmed = text.trim();
int words = trimmed.isEmpty() ? 0 : trimmed.split("\\s+").length;
System.out.println(words);
}
}
I'm working on a new application and i need to make a messages interface with lookup, using the key to find the value (like ConstantsWithLookup, but capable to receive parameters). I have being investigating Dictionary class functionality but it lacks message customization through parameters.
With ConstantsWithLookup i can make the following:
myConstantsWithLookupInterface.getString("key");
and get something like:
Field must be filled with numbers
But i need to do this:
myMessagesWithLookupInterface.getString("key", "param1", "param2",...);
and get something like:
Field _param1_ must be filled with numbers greater than _param2_
I have no clue how to do this.
Use GWT regular expressions:
//fields in your class
RegEx pattern1 = RegEx.compile("_param1_");
RegEx pattern2 = RegEx.compile("_param2_");
public String getString(String key, String replace1, String replace2){
// your original getString() method
String content = getString(key);
content = pattern1.replace(content,replace1);
content = pattern2.replace(content,replace2);
return content;
}
If your data contains Field _param1_ must be filled with numbers greater than _param2_ then this will replace _param1_ with content of string replace1.
