Hi HN, author here.

I built this because I was tired of VS Code freezing or crashing whenever I accidentally opened a multi-gigabyte log file. While less or tail -f are great, I wanted the IDE features (regex search, copy-paste, highlighting) without the context switch.

This is a VS Code extension that spawns a Rust sidecar to handle the heavy lifting.

How it works:

1. I/O: It uses memmap2 to map the file into memory. This lets the OS manage paging, so opening a 10GB file consumes virtually no heap memory in the process.

2. Indexing: On load, it does a single pass to build a line index (Vec<u64> offsets). This allows O(1) access to any specific line range.

3. Frontend: The UI is a Webview with aggressive virtualization. Since browsers have a limit on element height (often around ~10M pixels), I implemented a coordinate scaling system to support scrolling through files with millions of lines.

4. Search: It runs in the Rust backend using the regex crate, streaming results back to the UI in chunks to avoid blocking the thread.

5. IPC: Communication happens via Stdin/Stdout JSON streaming.

Features:

- Instant open for large files (tested up to ~10GB).

- Follow mode (tail -f implementation with 500ms polling).

- Filtering that keeps real line numbers (useful for correlating with stack traces).

- Cross-platform binaries included (Mac/Linux/Win).

The code is open source, and I'd love to hear your thoughts on the Rust implementation, especially regarding the mmap safety or potential optimizations for the search logic.

I'm not looking for low hanging fruit, and I'm definitely not looking for links to products that "change the world." No attention sneakers. What I want to glean is: when you say, "I'm going to push exposure for my product today," what are the actual core things you do? How often do you do them? And what outcomes do you realistically expect?

For example, we're planning to host monthly events in SF to help other founders and operators learn something genuinely useful. (not "use our product," but "here's how to do x,y,z, sponsored by us.") Then we follow it with a: "Join our Discord to keep the conversation going and meet people like you."

We're still small, so we hired someone entry level to post content on social every day to build momentum, with the hope of identifying a spark we can double down on messaging-wise.

I could go on, but if no one reads or comments, it disappears into the ether. So I'll stop here and hope this grows into something we can all learn from, without fluff or shameless self-promotion getting in the way.
