Estimated Reading Time for Blog Posts, Articles, etc.

A simple Kotlin/Java implementation of Medium's Read Time calculation.

Examples (TL;DR)

import net.thauvin.erik.readingtime.ReadingTime

// ...

val rt = ReadingTime(htmlText)
println(rt.calcEstimatedReadTime()) // eg: 2 min read

To get the estimated reading time in seconds use the calcReadingTimeInSec() function.

• View Kotlin or Java Examples.

Gradle, Maven, etc.

To use with Gradle, include the following dependency in your build file:

repositories {
    mavenCentral()
}

dependencies {
    implementation("net.thauvin.erik:readingtime:0.9.1")
}

Instructions for using with Maven, Ivy, etc. can be found on Maven Central.

The following properties are available:

    text,
    wpm = 275,
    postfix = "min read",

    excludeImages = false, 
    extra = 0,
    roundingMode = RoundingMode.HALF_EVEN
)

ReadingTime.imgCount(htmlText) // Returns the count of images. (HTML img tags)

JSP

A JSP tag is also available for easy incorporation into web applications:

<%@taglib uri="https://erik.thauvin.net/taglibs/readingtime" prefix="t"%>
<t:readingtime
    wpm="275"
    postfix="min read"
    plural="min read"
    excludeImages="false"
    extra="0">some_text</t:readingtime>

None of the attributes are required.
