C# Humanizer
last modified July 6, 2023
In this article we use the Humanizer.Core library to humanize strings, datetimes, numbers, and quantities. By humanizing we mean making information easier to understand for people.
$ dotnet add package Humanizer.Core
We add the library to our project.
Transforming text
The Transform method transforms a string using the provided
transformers.
using Humanizer; Console.OutputEncoding = System.Text.Encoding.UTF8; var msg = "an old falcon in the sky"; Console.WriteLine(msg.Transform(To.LowerCase)); Console.WriteLine(msg.Transform(To.SentenceCase)); Console.WriteLine(msg.Transform(To.TitleCase)); Console.WriteLine(msg.Transform(To.UpperCase)); var msg2 = "старый сокол в небе"; Console.WriteLine(msg2.Transform(To.LowerCase)); Console.WriteLine(msg2.Transform(To.SentenceCase)); Console.WriteLine(msg2.Transform(To.TitleCase)); Console.WriteLine(msg2.Transform(To.UpperCase));
In the program, we transform the case of the strings.
$ dotnet run an old falcon in the sky An old falcon in the sky An Old Falcon in the Sky AN OLD FALCON IN THE SKY старый сокол в небе Старый сокол в небе Старый Сокол В Небе СТАРЫЙ СОКОЛ В НЕБЕ
Truncating string
When we cannot show the whole string in the display, it is a common practice to shorten the string with a truncation suffix (usually three dots).
using Humanizer; var msg = "an old falcon in the sky"; Console.WriteLine(msg.Truncate(15)); Console.WriteLine(msg.Truncate(15, Truncator.FixedLength, TruncateFrom.Left)); Console.WriteLine(msg.Truncate(15, "...", TruncateFrom.Left)); Console.WriteLine(msg.Truncate(15, "...")); Console.WriteLine(msg.Truncate(4, "...", Truncator.FixedNumberOfWords)); Console.WriteLine(msg.Truncate(15, "...", Truncator.FixedNumberOfCharacters));
We use the Truncate method to shorten a string. We can shorten
strings based on chars or words. The strings can be shortened from right or
from left.
$ dotnet run an old falcon … …con in the sky ...n in the sky an old falco... an old falcon in... an old falcon i...
Roman numerals
We can transform numbers from Arabic to Roman numerals.
using Humanizer;
int[] vals = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 20, 100, 125, 500, 1000, 1555 };
var nromans = new List<string>();
var narabic = new List<int>();
foreach (var e in vals)
{
nromans.Add(e.ToRoman());
}
var rliterals = new string[]
{
"I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX", "X", "XI",
"XX", "C", "CXXV", "D", "M", "MDLV"
};
foreach (var e in rliterals)
{
narabic.Add(e.FromRoman());
}
Console.WriteLine(string.Join(",", nromans));
Console.WriteLine(string.Join(",", narabic));
We define an array of numbers. We transform them to Roman numerals and then back to Arabic numerals.
nromans.Add(e.ToRoman());
The ToRoman converts the value to Roman number.
narabic.Add(e.FromRoman());
The FromRoman converts Roman numbers into Arabic numbers.
$ dotnet run I,II,III,IV,V,VI,VII,VIII,IX,X,XI,XX,C,CXXV,D,M,MDLV 1,2,3,4,5,6,7,8,9,10,11,20,100,125,500,1000,1555
Transforming numbers to words
The ToWords method transforms a number into a word. The
ToOrdinalWords transforms a number into an ordinal word.
using Humanizer;
int[] vals = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 20, 100, 125, 500, 1000, 1555 };
foreach (var e in vals)
{
Console.WriteLine(e.ToWords());
}
Console.WriteLine("-------------------------");
foreach (var e in vals)
{
Console.WriteLine(e.ToOrdinalWords());
}
We have an array of integer values. These are transformed into words and ordinal words.
$ dotnet run one two three four five six seven eight nine ten eleven twenty one hundred one hundred and twenty-five five hundred one thousand one thousand five hundred and fifty-five ------------------------- first second third fourth fifth sixth seventh eighth ninth tenth eleventh twentieth hundredth hundred and twenty-fifth five hundredth thousandth thousand five hundred and fifty-fifth
Singularize & pluralize words
The Singularize method singularizes the provided input considering
irregular words while the Pluralize method pluralizes it.
using Humanizer;
var words = new string[]
{
"geese", "octopi", "mice", "passers-by", "men", "men-servants",
"dormice", "lice", "teeth", "feet"
};
foreach (var word in words)
{
Console.WriteLine(word.Singularize());
}
Console.WriteLine("-------------------------");
var words2 = new string[]
{
"goose", "octopus", "mouse", "passer-by", "man", "man-servant",
"dormouse", "louse", "tooth", "foot"
};
foreach (var word in words2)
{
Console.WriteLine(word.Pluralize());
}
We singularize and pluralize a bunch of English words.
$ dotnet run goose octopus mouse passers-by man men-servant dormice louse tooth foot ------------------------- geese octopi mice passer-bies men man-servants dormouses lice teeth feet
Note that passer-by, man-servant and dormouse words were incorrectly inflected.
Dates and times
We can humanize datetime values with Humanize.
using Humanizer; using Humanizer.Localisation; Console.WriteLine(TimeSpan.FromDays(486).Humanize(maxUnit: TimeUnit.Year)); Console.WriteLine(TimeSpan.FromDays(486).Humanize(precision: 3, maxUnit: TimeUnit.Year)); Console.WriteLine(TimeSpan.FromMinutes(1600).Humanize(4)); Console.WriteLine(TimeSpan.FromMinutes(1600).Humanize()); Console.WriteLine(TimeSpan.FromMinutes(1600).Humanize(maxUnit: TimeUnit.Hour)); Console.WriteLine(TimeSpan.FromMilliseconds(5553005).Humanize(3)); Console.WriteLine(DateTime.UtcNow.AddHours(-30).Humanize()); Console.WriteLine(DateTime.UtcNow.AddHours(-2).Humanize()); Console.WriteLine(DateTime.UtcNow.AddHours(30).Humanize()); Console.WriteLine(DateTime.UtcNow.AddHours(2).Humanize());
The precision option sets the maximum number of time units to
return. The default is 1 which means the largest unit is returned. The
maxUnit sets the maximum unit of time to output.
$ dotnet run 1 year 1 year, 3 months, 29 days 1 day, 2 hours, 40 minutes 1 day 26 hours 1 hour, 32 minutes, 33 seconds yesterday 2 hours ago tomorrow an hour from now
