A minimal, declarative setup for productive Rust hacking on Emacs + Guix

I noticed there was a blatant lack of resources and documentation on this particular setup. So I rolled up my sleeves and wrote this article, which hopefully you find useful.

Automated changelog generation

When publishing a package for use by programmers, automated changelog generation is very beneficial. In this blog post, I explore how to do it in a simple way that works everywhere.

Introducing: Loki! An all-in-one, batteries-included LLM CLI tool

Loki started out as a fork of the fantastic AIChat CLI, where I just wanted to give it first-class MCP server support. It has since evolved into a massive passion project that's a fully-featured tool with its own identity and extensive capabilities! My goal is to make Loki a true "all-in-one" and "batteries-included" LLM tool.

Check out the release notes for a quick overview of everything Loki can do!

What Makes Loki Different From AIChat?

• First-class MCP support, with support for both local and remote servers
  • Agents, roles, and sessions can all use different MCP servers and switching between them will shutdown any unnecessary ones and start the applicable ones
  • MCP sampling is coming next
• Comes with a number of useful agents, functions, roles, and macros that are included out-of-the-box
• Agents, MCP servers, and tools are all managed by Loki now; no need to pull another repository to create and use tools!
  • No need for any more *.txt files
• Improved DevX when creating bash-based tools (agents or functions)
  • No need to have argc installed: Loki handles all the compilation for you!
  • Loki has a --build-tools flag that will build your bash tools so you can run them exactly the same way Loki would
  • Built-in Bash prompting utils to make your bash tools even more user-friendly and flexible
• Built-in vault to securely store secrets so you don't have to store your client API keys in environment variables or plaintext anymore
  • Loki also will inject additional secrets into your agent's tools as environment variables so your agents can also use secrets securely
• Multi-agent support out-of-the-box: You can now create agents that route requests to other agents and use multiple agents together without them trampling all over each other's binaries
• Improved documentation for all the things!
• Simplified directory structure so users can share full Loki directories and configurations without massive amounts of data, or secrets being exposed accidentally

What's Next?

• MCP sampling support, so that MCP servers can send back queries for the LLM to respond to LLM requests. Essentially, think of it like letting the MCP server and LLM talk to each other to answer your query
• Give Loki a TUI mode to allow it to operate like claude-code, gemini-cli, codex, and continue. The objective being that Loki can function exactly like all those other CLIs or even delegate to them when the problem demands it. No more needing to install a bunch of different CLIs to switch between!
• Integrate with LSP-AI so you can use Loki from inside your IDEs! Let Loki perform function calls, utilize agents, roles, RAGs, and all other features of Loki to help you write code.

Typst 0.14 was released. Bringing super cool new features and fixes to typst.

Typst is getting an even better alternative to latex.

Managarr v0.6.0 has been released with some fun new features!

Managarr is a terminal-based application for managing all your Servarr instances from one place. It provides a user-friendly interface to interact with your media libraries, making it easier to manage your downloads, monitor your series and movies, and perform various actions directly from the terminal.

It sports two modes: a TUI mode (Text User Interface) and a CLI mode (Command Line Interface).

TUI mode gives you an interactive User Interface right inside your terminal window, allowing you to navigate through your Sonarr and Radarr libraries, view details about your series and movies, and perform actions like adding or removing items, all through keyboard shortcuts.

CLI mode lets you execute commands directly from the terminal to manage your Servarr instances without needing to open the TUI. This is great for quick tasks or for integrating with scripts and automation tools.

The biggest change: Managarr now has themes!

The UI has been completely overhauled to support themes! You can now customize the look and feel of Managarr to suit your preferences. Choose from a variety of themes to change the color scheme and overall aesthetic of the application.

Here's just a few examples:

Default

Dracula

Watermelon Dark

You can also customize the themes to your heart's content! Check out the themes documentation for more details on how to create and apply your own themes.

Features

• Added support for alternative Vim-like navigation keybindings (hjkl movements) Discussion #34
• Added support for terminal-like backspace operations (Ctrl-h instead of Backspace)
• You can now specify the number of downloads to fetch from the CLI: managarr <sonarr/radarr> list downloads --count 1234
• You can now toggle movie monitoring from the CLI without needing to use the edit subcommand: managarr radarr toggle-movie-monitoring --movie-id 1234 #43
• You can also now toggle series monitoring from the CLI without needing to use the edit subcommand: managarr sonarr toggle-series-monitoring --series-id 1234 #43
• You can now also toggle movie/series monitoring directly from the Library view for each Servarr with the m key. No need to open the Edit [Series/Movie] modal anymore to simply toggle monitoring for an item! #43
• Users can now skip up/down tables 20 items at a time using Ctrl-d and Ctrl-u keys (mirroring the same functionality in the Helix editor). Alternatively, the standard PgUp and PgDown keys are supported for the same operation. This is particularly useful for large libraries with many items #45
• The total disk usage for any given series is now displayed in the Series Library view to mirror Radarr functionality #44
• All keybindings and help tips have been refactored into a unified, dynamic menu that displays the available keybindings for the current view. This is accessible by pressing ? in any view, and it will display the keybindings relevant to that view. #32
• Users can now add any number of custom headers to each Servarr's configuration, enabling support for OAuth and other custom authentication schemes for Servarr access #47

Fixes

• Fixed a bug that caused the Collection Details modal to vanish when attempting to add a new film to a collection
• Fixed a bug that caused the Radarr library to be rendered, then the Collections table to be rendered over it (merging the two), and then showing a popup which made for ugly and confusing UI
• Wrapped Season.statistics with Option to prevent a panic if the season doesn't have any statistics (edge-case, only happens with outdated Sonarr data) #35
• Corrected a bug that caused double key presses on Windows machines #40 (Thanks @cwesleys!)
• Defaulted to empty tags to improve fault tolerance within the Sonarr and Radarr UIs. This is in response to #42, #48. It seems like this may be a bug in Sonarr where a series can have an associated tag ID but that tag Id doesn't exist in the list of tags, but I still can't quite track it down.
• Fixed an issue that caused some panics to occur when video codecs are undefined in file metadata #38
• More than 10 downloads will be listed in the Downloads tabs for both Radarr and Sonarr
• Fixed a bug where Sonarr would have empty values on season releases for seeders/leechers instead of '0'
• Fixed a bug where some Radarr films don't have studios associated with them, so the studio field is now nullable, preventing crashes when loading the Radarr library

Security Fixes

• Upgraded to the most recent version of Tokio to mitigate CWE-664 Improper Control of a Resource Through its Lifetime
• Updated to the most recent patch of OpenSSL to mitigate CWE-416 Use-After-Free

Minor Changes

• Due to the new support for Vim-like navigation keybindings, the system logs are now opened using L instead of l
• Refactored the network module to be more idiomatic Rust and to improve maintainability

Documentation

• Update README.md to remove the cheeky Try Before You Buy heading since some users reported it as misleading; i.e. they thought it meant Managarr cost money. Managarr is and always will be, free

As always, thank you to everyone who reported an issue or requested a feature! You all make it a LOT easier to keep up with breaking API and add new features. If you have any feedback or suggestions, please don't hesitate to open an issue or discussion on the GitHub repository.

https://pest.rs/book/examples/awk.html 🎉

I aimed to keep it in line with the "demonstration of the Rust ecosystem" goal, so it can also be a great introduction to Rust for beginners who are looking for a fun project to work on. It's not perfect, but that's part of the fun! It leaves room for potential language extensions (to make the AWK clone more complete) and optimizations up to the reader as a follow-up.

The Integrity Data Platform (IDP) team decided to rewrite one of our heavy Queries Per Second (QPS) Golang microservices in Rust. It resulted in 70% infrastructure savings at a similar performance, but was not without its pitfalls.

This is a new password manager I wrote in Rust. This is supposed to replace 'passage' which I used previously. WDYT?

i made a gallery generator for my film photos! it uses Atkinson dithering (optional) for thumbnails and outputs clean static HTML with zero JavaScript.

this is actually my first Rust project that i've shipped, so i'm totally open to contributions, suggestions, or critiques.

I've found this to be pretty useful when needing to do recursive / multi-file search and replace. Also has bindings to work within terminal text editors like vim and helix.

Uses rust and ripgrep under the hood for speed.
