I have an array that I am trying to localize and for the most part it works. Where I have a problem is in trying to get a value returned from the Localizable.strings file for any value that contains a space in my base language, for example with "Blue Cheese" I've tried putting the key in quotes and also tried various ways to escape the space but have no luck. Any ideas would be greatly appreciated. I know I could do this with other approaches but none of them seem as simple as what I am trying which also saves me from having to define all of the items in the base language Localizable.strings file. The actual array has many more items than the example below.
func fillFoodArray () {
var foodChoices = ["Veal","Chicken","Turkey","Charcuterie","Lamb","Blue Cheese"]
foodArray.removeAll(keepCapacity: true)
for food in foodChoices {
foodArray.append(NSLocalizedString(food,comment:food))
}
}
Have you tried to initialize the array with localization?
var foodChoices = [
NSLocalizedString("Veal", comment:"Comment for Veal"),
NSLocalizedString("Chicken", comment:"Comment for Veal"),
NSLocalizedString("Turkey", comment:"Comment for Veal"),
NSLocalizedString("Charcuterie", comment:"Comment for Veal"),
NSLocalizedString("Lamb", comment:"Comment for Veal"),
NSLocalizedString("Blue Cheese", comment:"Comment for Veal")
]

the problem is that the text has value which declares the day before the text
so idk how to translate this text that includes value.
untilEventDay =
'${pDate.difference(DateTime.now()).inDays},days/ until event day'
.tr;
in translation page :
,days/ until next event day': 'ڕؤژ ماوه/ تاوهكو ئیڤێنتی داهاتوو',
you should separate the value's string from your translation
var eventDayCountDownTitle = '${pDate.difference(DateTime.now()).inDays}' + ',' + days/ until event day'.tr;
and if you need your day number to be in a specific language, you can use a map or a helper method. map solution would be something like this:
Map<String,String> englishToPersianNumber = {'1' : '۱'}
and then use it in your string :
englishToPersianNumber[pDate.difference(DateTime.now()).inDays.toString()]
Important: to have a cleaner code, you can create a helper method to generate your desired string, and call it in your text widget. the code would be more understandable that way. Also, you can add handle any conditions that may later be added to the string generator. like if it's the last day, write something else instead of 0 days remaining.
String eventDayCountDownTitle(int remainingDays) {
if(remainingDays == 0) return "Less than One day to the event".tr;
return '${remainingDays.toString}' + ',' + 'days/ until event day'.tr;
}
ps. your question's title is wrong, you should change it to what you're explaining in the caption
First, I'm very new to Swift, and coding in general. I'm trying to use the correct terminology, so I apologize if it makes no sense. Doing my best!
Ok, so there appears to be a lot of information/answers on ways to random select strings (or integers, etc) from an array without repetition. However, in my current application, I am not using an array (I kind of am but not directly related to the question). But rather a #State designation, in which the variable has an initial value (a string with a number and letter) and is later updated when a button is pushed. The string changes to a randomly selected string from my assets folder based on the file name, which will be the same word but with a different number and letter. What is the simplest way to keep from updating to strings that have already appeared?
Example of what the code looks like:
#State var relevantWord = "bird"
Button {
let randoNum = Int.random(in: 1...5)
let x = ["a", "b", "c", "d"]
let randoLet = x.randomElement()
relevantWord = "bird" + String(randoNum) + String(randoLet)
}
So, the relevantWord variable starts as "bird2c" for example, and each time the button is pushed, it will change to "bird3b" then "bird4a" etc. I just want to keep it from repeating and return nothing when the assets are depleted. Thanks!
Currently I'm working in a project with flutter, but I realize there is a need in the management of the variables I'm using.
Basically I want to delete the last character of a string I'm concatenating, something like this:
string varString = 'My text'
And with the help of some method or function, the result I get:
'My tex'
Am I clear about it? I'm looking for some way which helps me to 'pop' the last character of a text (like pop function in javascript)
Is there something like that? I search in the Dart docs, but I didn't find anything about it.
Thank you in advance.
You can take a substring, like this:
string.substring(0, string.length - 1)
If you need the last character before popping, you can do this:
string[string.length - 1]
Strings in dart are immutable, so the only way to do the operation you are describing is by constructing a new instance of a string, as described above.
var str = 'My text';
var newStr = (str.split('')..removeLast()).join();
print(newStr);
Another way:
var newStr2 = str.replaceFirst(RegExp(r'.$') , '');
print(newStr2);
I'm porting my Swift app to Flutter and for localising it I'm following this https://github.com/billylev/flutter_localizations but I can't see how to insert placeholder to insert a value in the translated values.
Basically the guide uses
String text(String key) {
return _localisedValues[key] ?? "$key not found";
}
to get the corresponding key:value pair from a .json file as
{
"Shop": "Negozio",
}
I just pass it in the Textwidget as :
Text(AppLocalizations.instance.text('Shop')).
How to modify text to insert one or more placeholders and how would be the .json be constructed?
Say for the value "User": "User" I'd like to insert a value after the transaction I can simply use a string sum and add the value as `Text(
AppLocalizations.instance.text('User') + ' ${widget.user.name}', but if I need to insert a value in the middle of the translated sentence, eg a message, I don't see how to accomplish it.
I need it to make localised versions of incoming push notification, and they have args.
In Swift I have it like this:
"ORDER_RECEIVED_PUSH_TITLE" = "Order number: %#";
"ORDER_RECEIVED_PUSH_SUBTITLE" = "Shop: %#";
"ORDER_RECEIVED_PUSH_BODY" = "Thank you %#! We received your order and we'll let you know when we start preparing it and when it's ready. Bye";
Any suggestions on how to accomplish that in Flutter?
Many thanks
I was suggested this package https://pub.dev/packages/sprintf#-installing-tab- and it works just as I needed. Sprintf just lets you specify one or more placeholders in a String and pass an array of args.
https://developermemos.com/posts/using-sprintf-flutter-dart. for more info, even this is pretty much it. So for example
"ORDER_RECEIVED_PUSH_TITLE" = "Order number: %#";
in the .json file would be :
{
"ORDER_RECEIVED_PUSH_TITLE": "Oder number: %s"
}
and using it would be
String orderNumber = 'some uuid';
Text(Sprintf(AppLocalitazions.instance.text('ORDER_RECEIVED_PUSH_TITLE'),[orderNumber]);
Hope this helps others.
I have this string: "C:\Procesos\rrhh\CorteDocumentos\Cortados\10001662-1_20060301_29_1_20190301.pdf" and im trying to get this part : "20190301". The problem is the lenght is not always the same. It would be:
"9001662-1_20060301_4_1_20190301".
I've tried this: item.ToString.Substring(66,8), but it doesn't work sometimes.
What can I do?.
This is a code example of what I said in my comment.
Sub Main()
Dim strFileName As String = ""
Dim di As New DirectoryInfo("C:\Users\Maniac\Desktop\test")
Dim aryFi As FileInfo() = di.GetFiles("*.pdf")
Dim fi As FileInfo
For Each fi In aryFi
Dim arrname() As String
arrname = Split(Path.GetFileNameWithoutExtension(fi.Name), "_")
strFileName = arrname(arrname.Count - 1)
Console.WriteLine(strFileName)
Next
End Sub
You could achieve this using a simple regular expressions, which has the added benefit of including pattern validation.
If you need to get exactly eight numbers from the end of file name (and after an underscore), you can use this pattern:
_(\d{8})\.pdf
And then this VB.NET line:
Regex.Match(fileName, "_(\d{8})\.pdf").Groups(1).Value
It's important to mention that Regex is by default case sensitive, so to prevent from being in a situations where "pdf" is matched and "PDF" is not, the patter can be adjusted like this:
(?i)_(\d{8})\.pdf
You can than use it directly in any expression window:
PS: You should also ensure that System.Text.RegularExpressions reference is in the Imports:
You can achieve it by this way as well :)
Path.GetFileNameWithoutExtension(Str1).Split("_"c).Last
Path.GetFileNameWithoutExtension
Returns the file name of the specified path string without the extension.
so with your String it will return to you - 10001662-1_20060301_29_1_20190301
then Split above String i.e. 10001662-1_20060301_29_1_20190301 based on _ and will return an array of string.
Last
It will return you the last element of an array returned by Split..
