TapeHead – A CLI tool for stateful random access of file streams

In plain words

TapeHead is a command-line tool for opening files and performing random access operations like seeking, reading, and writing while maintaining state. Created for debugging a driver when existing tools fell short, it serves developers and system engineers who need direct file manipulation capabilities. The tool enables stateful interaction with file streams through a CLI interface, making it useful for low-level debugging and file handling tasks.

CLI tool for stateful random access of file streams - emamoah/tapehead

File: "test.txt" (67 bytes) [RW] [pos:0]> seek 10 [pos:10]> read . 5 ello! [in:5, pos:15]> read 9 5 hello [in:5, pos:14]> quit Screen recording demo The tool runs a REPL session in which you can run commands to read, write, and seek to any position within the file stream. It's quite useful for tasks like debugging a driver, or anything that has to do with file streams. cargo install --git https://github.com/emamoah/tapehead.git Motivation I wrote a shabby version of this when I was trying to debug my scull driver , which controls a simple virtual character device. I was amazed I couldn't find a tool that allowed me to statefully seek, read and write to a file, so I just improvised some…from github.com

  Tailspin – A Log File Highlighter2023 · github.com · ▲139

  There are multiple programs for working with log files, both inside and outside of the terminal. These tools are feature rich and functional and offer lots of control to the user. However, a lot of the time I found myself just opening raw log files in `less`. I enjoy the simplicity of quickly skimming through the logs, but it was difficult when the wall of text was in one color. For this reason, I created a command line tool called `tailspin` (the name is a take on the `tail` command) that did one thing: highlighting of log files. It is configurable, but requires no setup. It defaults to…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser.
