Kotlin Viewer

Open and inspect Kotlin source in a browser-based code viewer with search and structural navigation. Processing stays in your browser.

Developer Input

Kotlin source

Kotlin Source Code

package com.example.viewer

class Greeter(private val prefix: String) {
    fun greet(name: String): String {
        return "$prefix, $name"
    }
}

Search Mode

query

Show line numbers Highlight keywords Generate outline Auto-run while typing

Paste source code or load the included working example.
Choose the search mode and adjust the additional setting.
Enable only the checks or output options needed for this review.
Select Render Viewer and inspect the output, status, and measured processing time.
Copy or download the result after reviewing heuristic findings.

This tool performs browser-based structural and static analysis. It does not replace the official Kotlin or Swift compiler.

Source input → string and comment masking → token or rule analysis → structured output → statistics and recommendations.

Heuristic findings are labeled for review. Confirm production code with the official compiler, IDE, and project test suite.

The loaded example is executable test input for the Kotlin Viewer. Run the tool to see its expected output and status.

Use complete declarations when possible so scope and block ranges can be estimated correctly.
Keep strings and comments intact; the analyzer masks them before structural processing.
Review every automatic conversion before replacing source in a production project.
Use the official compiler for final syntax, type, dependency, and platform validation.

How can I view Kotlin code with line numbers online?

Paste Kotlin source and the viewer renders numbered lines with basic syntax highlighting and code statistics.

Can I search Kotlin source code using regular expressions?

Yes. Select regex search mode and enter a valid JavaScript-compatible regular expression.

How do I navigate to Kotlin functions in a large file?

The generated outline lists detected classes and functions so you can review their line positions quickly.

Can this Kotlin viewer handle large source files?

It is designed for large text inputs and switches to a simplified rendering strategy when the source is very large.

Does the Kotlin viewer modify my code?

No. It escapes and highlights the source for display while preserving the original input.

Module	Purpose
Search Mode	Plain, case-sensitive, or regex search.
Outline	Lists detected declarations and line numbers.
Line View	Renders source with optional line numbers.
