FuzzyFinder – in 10 lines of Python

In plain words

FuzzyFinder is a Python tool that implements the fuzzy file-finding feature common in code editors. It filters a collection of filenames based on partial string input, allowing users to locate files by typing fragments from the full path rather than complete names. The tool demonstrates how to narrow down file suggestions as users type, making it useful for developers who want to understand or implement similar search functionality.

From the sources

FuzzyFinder is a popular feature available in decent editors to open files. The idea is to start typing partial strings from the full path and the list of suggestions will be narrowed down to match the desired file. This is an extremely useful feature and it's quite easy to implement. We have a collection of strings (filenames). We're trying to filter down that collection based on user input. The user input can be partial strings from the filename. Let's walk this through with an example. Here is a collection of filenames: When the user types 'djm' we are supposed to match ' dj ango_ m igrations.py' and ' dj ango_ad m in_log.py'. The simplest route to achieve this is to use regular…from blog.amjith.com

  Haystack – an IDE for exploring and editing code on an infinite canvas2024 · haystackeditor.com · ▲546

  Hi HN, we’re building Haystack Editor (https://haystackeditor.com/), a canvas-based IDE that automates the boring stuff (plumbing, refactoring, and finding code) so that you can focus on the exciting parts of software development! You can see a quick overview of Haystack at https://www.youtube.com/watch?v=c2uZnR5D_cc! (It's currently only on Mac OS but we're working on Linux and Windows. Edit: just added a Linux download!) Haystack was born out of our frustrations with working in large and mature codebases, specifically with navigating and editing functional…

  Frontend Fuzzy Search2024 · github.com · ▲120

  I have spent several years working on search engines in the backend and have now utilized that experience to develop a fuzzy search library for the frontend. It's fast, accurate and can be used for all languages. It should be easy to integrate into your Javascript / Typescript projects. If you test it and find any edge cases that did not work for you please let me know. The implementation is based on 3-grams by the book, augmented with a novel trick of sorting the characters within the 3-grams for enhanced accuracy. For a detailed explanation you may refer to my related blog post at…

  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…
