InLine

!! Deprecation warning !!

I'm not interested in developing InLine and using IntelliJ IDEA anymore since JetBrains dropped support for Free Rust Plugin and started focusing on new UI that is IMO ugly. I don't like the direction this IDE is going and decided to switch away.

You should consider using alternative plugins:

• Inspection Lens
• Inline Problems

You can consider using alternative IDE:

• VSCode - feature & plugin Rich IDE with not great UI (By Microsoft).
• Lapce - Middleground between VIM & VSCode with fast user-friendly UI similar to old IntelliJ IDEA UI, modal editing and built-in LSP & Inline errors. Lacks certain features, But is written in Rust so you can contribute.

InLine is highly customizable plugin that shows errors and hints inline.

Also supports gutter icons, colorful background and special effects.

• Errors are filtered on the line by priority
• Supports different fonts and languages
• Supports different hints styles After Line, Rust Style

Settings > Appearance & Behaviour > ⚙ InLine

Shortcuts:

• Hide/Show all errors alt K
• Change text style (After/Underline) alt L

In plugin settings you can:

• Show or hide specific level of errors - error, warning, weak warning, information
• Change text colors & text visibility for each error level
• Change text style to make it appear after line end or under line
• Change background colors & background visibility for each error level
• Change gutter icons visibility for each error level and select number of gutter icons
• Apply additional effect
• Change font of the hints
• Ignore some errors by description

Choices

There are already multiple plugins like this inspired by VSCode ErrorLens extension - check Inspired by section. I've decided to make my own because I want to have some extra features for code writing and demonstration purposes such as:

• Fill background of whole line
• Show error icons in gutter area for different kinds of errors
• Turn hint text off but make background stay

Future

In the future I am planning to add more customization such as:

• New effects
• Error description changing
• Additional ways to filter errors
