DailyTags

DailyTags is a flexible markdown library that supports custom tags and markups.

The library parses a given markup into rich text for Jetpack Compose. DailyTags comes with Markdown and HTML support by default (please, see the supported features) and is very easy to extend to support custom markups.

The library parses text source into nodes which are then styled using AnnotatedString. No WebView is required. All you need is to create a rule that defines how the text is extracted and styled. More examples below!

DailyTags aims to be:

• ⚡ fast
• 🪶 lightweight(less than 50kb)
• 👋 easy to use
• 🏗️ extensible
• 📎 flexible

The library provides defaults to display Markdown content along with giving all the means to tweak the appearance as much as you wish!This repository contains DailyTags source code and a sample app.

📦 Installation

Add the following configuration to the build.gradle files:

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation "com.github.DmytroShuba:DailyTags:1.0.0"
}

🔨 Usage

Markdown

DailyTags supports most of the Markdown features, but not all (the supported features).

To parse Markdown content use SimpleMarkupParser and MarkdownRules together:

val source = "Hello world"
val rules = MarkdownRules.toList()
val parser = SimpleMarkupParser()
val content = parser
    .parse(source, rules)
    .render()
    .toAnnotatedString()

Text(text = content)

Markdown and HTML

val source = "Hello world"
val rules = MarkdownRules.toList() + HtmlRules.toList()
val parser = SimpleMarkupParser()
val content = parser
    .parse(source, rules)
    .render()
    .toAnnotatedString()

Text(text = content)

Custom tags

1. Create a pattern with a regular expression to find the specified content.

val PATTERN_HIGHLIGHT_BLUE = Pattern.compile("^
   
    ([
    \s\S]+?)<
    \/hl-blue>
    "
   )

2. Create rules for your patterns. A rule includes the pattern and styling configuration for the matched content:

val blueRule = PATTERN_HIGHLIGHT_BLUE.toRule(spanStyles = SpanStyle(color = Color.Blue))

3. Use custom rules when parsing the content:

val parser = SimpleMarkupParser()
val rules = listOf(blueRule, ...)
val content = parser
    .parse(source, rules)
    .render()
    .toAnnotatedString()
