# 4.3.0-SNAPSHOT
* add `MarkwonInlineParserPlugin` in `inline-parser` module
* `JLatexMathPlugin` now supports both inline and block structures
this comes with a breaking change: `JLatexMathPlugin` now depends on `inline-parser` module and `MarkwonInlineParserPlugin` must be explicitly added to a `Markwon` instance:
```java
final Markwon markwon = Markwon.builder(this)
.usePlugin(MarkwonInlineParserPlugin.create())
.usePlugin(JLatexMathPlugin.create(textSize))
.build();
```
* `JLatexMathPlugin` now supports inline LaTeX structures via `MarkwonInlineParserPlugin`
dependency (must be explicitly added to `Markwon` whilst configuring)
* `JLatexMathPlugin`: add `theme` (to customize both inlines and blocks)
* `JLatexMathPlugin`: add `renderMode` to use previous (pre `4.3.0`) LaTeX rendering (`LEGACY` & `BLOCKS_AND_INLINES`)
* add `JLatexMathPlugin.ErrorHandler` to catch latex rendering errors and (optionally) display error drawable ([#204])
* `JLatexMathPlugin` add text color customization ([#207])
* `JLatexMathPlugin` will use text color of widget in which it is displayed **if color is not set explicitly**

<MavenBadge4 :artifact="'ext-latex'" />
This is an extension that will help you display LaTeX formulas in your markdown.
Syntax is pretty simple: pre-fix and post-fix your latex with `$$` (double dollar sign).
`$$` should be the first characters in a line.
This is an extension that will help you display LaTeX content in your markdown.
Since <Badge text="4.3.0" /> supports both blocks and inlines markdown structures (blocks only before `4.3.0`).
## Blocks
Start a line with 2 (or more) `$` symbols followed by a new line:
```markdown
$$
\\text{A long division \\longdiv{12345}{13}
$$
```
LaTeX block content will be considered ended when a starting sequence of `$` is found on
a new line. If block was started with `$$$` it must be ended with `$$$` symbols.
## Inline
Exactly `$$` before and after _inline_ LaTeX content:
```markdown
$$\\text{A long division \\longdiv{12345}{13}$$
```
:::warning
By default inline nodes are disabled and must be enabled explicitly:
```java
Markwon.builder(context)
.use(JLatexMathPlugin.create(textSize))
.build();
final Markwon markwon = Markwon.builder(this)
// required plugin to support inline parsing
.usePlugin(MarkwonInlineParserPlugin.create())
.usePlugin(JLatexMathPlugin.create(textView.getTextSize(), new JLatexMathPlugin.BuilderConfigure() {
@Override
public void configureBuilder(@NonNull JLatexMathPlugin.Builder builder) {
// ENABLE inlines
builder.inlinesEnabled(true);
}
}))
.build();
```
Please note that usage of inline nodes **require** [MarkwonInlineParserPlugin](../inline-parser/)
:::
This extension uses [jlatexmath-android](https://github.com/noties/jlatexmath-android) artifact to create LaTeX drawable.
## Config
```java
final Markwon markwon = Markwon.builder(context)
.usePlugin(JLatexMathPlugin.create(textSize, new BuilderConfigure() {
// create default instance of plugin and use specified text size for both blocks and inlines
JLatexMathPlugin.create(textView.getTextSize());
// create default instance of plugin and use specified text sizes
JLatexMathPlugin.create(inlineTextSize, blockTextSize);
JLatexMathPlugin.create(textView.getTextSize(), new JLatexMathPlugin.BuilderConfigure() {
@Override
public void configureBuilder(@NonNull JLatexMathPlugin.Builder builder) {
// enable inlines (require `MarkwonInlineParserPlugin`), by default `false`
builder.inlinesEnabled(true);
// use pre-4.3.0 LaTeX block parsing (by default `false`)
builder.blocksLegacy(true);
// by default true
builder.blocksEnabled(true);
// @since 4.3.0
builder.errorHandler(new JLatexMathPlugin.ErrorHandler() {
@Nullable
@Override
public void configureBuilder(@NonNull Builder builder) {
builder
.align(JLatexMathDrawable.ALIGN_CENTER)
.fitCanvas(true)
.padding(paddingPx)
// @since 4.0.0 - horizontal and vertical padding
.padding(paddingHorizontalPx, paddingVerticalPx)
// @since 4.0.0 - change to provider
.backgroundProvider(() -> new MyDrawable()))
// @since 4.0.0 - optional, by default cached-thread-pool will be used
.executorService(Executors.newCachedThreadPool());
public Drawable handleError(@NonNull String latex, @NonNull Throwable error) {
// Receive error and optionally return drawable to be displayed instead
return null;
}
}))
.build();
});
// executor on which parsing of LaTeX is done (by default `Executors.newCachedThreadPool()`)
builder.executorService(Executors.newCachedThreadPool());
}
});
```
## Theme
```java
JLatexMathPlugin.create(textView.getTextSize(), new JLatexMathPlugin.BuilderConfigure() {
@Override
public void configureBuilder(@NonNull JLatexMathPlugin.Builder builder) {
// background provider for both inlines and blocks
// or more specific: `inlineBackgroundProvider` & `blockBackgroundProvider`
builder.theme().backgroundProvider(new JLatexMathTheme.BackgroundProvider() {
@NonNull
@Override
public Drawable provide() {
return new ColorDrawable(0xFFff0000);
}
});
// should block fit the whole canvas width, by default true
builder.theme().blockFitCanvas(true);
// horizontal alignment for block, by default ALIGN_CENTER
builder.theme().blockHorizontalAlignment(JLatexMathDrawable.ALIGN_CENTER);
// padding for both inlines and blocks
builder.theme().padding(JLatexMathTheme.Padding.all(8));
// padding for inlines
builder.theme().inlinePadding(JLatexMathTheme.Padding.symmetric(16, 8));
// padding for blocks
builder.theme().blockPadding(new JLatexMathTheme.Padding(0, 1, 2, 3));
// text color of LaTeX content for both inlines and blocks
// or more specific: `inlineTextColor` & `blockTextColor`
builder.theme().textColor(Color.RED);
}
});

## `@since` annotation
Although it is not required it is a nice thing to do: add `@since $VERSION` comment to the code
whenever it is possible (at least for publicly accessible code - API). This would help
navigating the project without the need to checkout the full VCS history. As keeping track of
current and/or upcoming version can be error-prone it is better to insert a generic `@since code`
that can be properly substituted upon a release.
For example, `@since $nap` seems like a good candidate. For this a live template can be created and used
whenever a new API method/field/functionality-change is introduced (`snc`):
```
@since $nap;
```
This live template would be possible to use in both inline comment and javadoc comment.
