[CLI Tool] Show HN: Linux CLI tool to provide mutex locks for long running bash ops Been exploring claude and spec-based coding, I think it turned out fairly successful.

[Other] Show HN: A 'Choose Your Own Adventure' written in Emacs Org Mode I authored and developed an interactive children&#x27;s book about entrepreneurship and money management. The journey started with Twinery, the open-source tool for making interactive fiction, discovered right here on HN. The tool kindled memories of reading CYOA style books when I was a kid, and I thought the format would be awesome for writing a story my kids could follow along, incorporating play money to learn about transactions as they occurred in the story.<p>Twinery is a fantastic tool, and I used it to layout the story map. I really wanted to write the content of the story in Emacs and Org Mode however. Thankfully, Twinery provided the ability to write custom Story Formats that defined how a story was exported. I wrote a Story Format called Twiorg that would export the Twinery file to an Org file and then a Org export backend (ox-twee) to do the reverse. With these tools, I could go back and forth between Emacs and Twinery for authoring the story.<p>The project snowballed and I ended up with the book in digital and physical book formats. The Web Book is created using another Org export backend.<p>Ten Dollar Adventure: <a href="https:&#x2F;&#x2F;tendollaradventure.com" rel="nofollow">https:&#x2F;&#x2F;tendollaradventure.com</a><p>Sample the Web Book (one complete storyline&#x2F;adventure): <a href="https:&#x2F;&#x2F;tendollaradventure.com&#x2F;sample&#x2F;" rel="nofollow">https:&#x2F;&#x2F;tendollaradventure.com&#x2F;sample&#x2F;</a><p>I couldn&#x27;t muster the effort to write a special org export backend for the physical books unfortunately and used a commercial editor to format these.<p>Twiorg: <a href="https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;twiorg">https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;twiorg</a><p>ox-twee: <a href="https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;ox-twee">https:&#x2F;&#x2F;github.com&#x2F;danishec&#x2F;ox-twee</a><p>Previous HN post on writing the transaction logic using an LLM in Emacs: <a href="https:&#x2F;&#x2F;blog.tendollaradventure.com&#x2F;automating-story-logic-with-llms&#x2F;" rel="nofollow">https:&#x2F;&#x2F;blog.tendollaradventure.com&#x2F;automating-story-logic-w...</a><p>Twinery 2: &lt;<a href="https:&#x2F;&#x2F;twinery.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;twinery.org&#x2F;</a>&gt; and discussion on HN: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32788965">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=32788965</a>

[DevOps] Show HN: GitGuard - Painless GitHub PR Automations Hey HN,<p>Every team I&#x27;ve been on has cobbled together some sort of combination of GitHub branch protections and custom scripts to make sure that PRs conform to organization policies and best practices.<p>Things like:<p>- When {X} file is changed, require review from team {Y}<p>- When a new db migration is added, ensure that a special set of tests pass<p>- Require multiple approvals when the PR is very large<p>- Add a special label to PRs that include breaking changes<p>- Allow emergencies &#x2F; hotfixes to break glass and bypass all of the above<p>Most teams tend to start out with a little script running in GitHub actions to enforce all of these policies but it tends to get out of hand and become hard to maintain. PRs that should require scrutiny slip through the cracks, and others that should be allowed through are unnecessarily blocked.<p>That&#x27;s why I made GitGuard (<a href="https:&#x2F;&#x2F;gitguard.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;gitguard.dev&#x2F;</a>)<p>GitGuard lets you write and maintain these policies in a custom DSL so simple it looks like pseudocode. The policies are checked on every single PR nearly instantly (no need to wait for a GitHub actions runner) and the results are reported in plain english.<p>Right now policies can make simple assertions about PR metadata and take some stateful actions (adding labels, requesting review) but I&#x27;d love to hear more from HN about how GitGuard could be even more useful.

[CLI Tool] Show HN: ggc – A terminal-based Git CLI written in Go Hi HN,<p>I built ggc (<a href="https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc">https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc</a>), a terminal-based Git CLI tool written in Go.<p>ggc provides: - A fast interactive UI (like `fzf`) for common Git operations<p>- Traditional subcommands (e.g. `ggc add`, `ggc commit`)<p>- Git-compatible config support (`ggc config` reads from `git config`)<p>- Built-in aliases and workflow automation (e.g. `ggc addcommitpush`)<p>The goal is to improve developer productivity by combining interactive workflows with scriptable CLI operations.<p>It&#x27;s still under active development, but I&#x27;d love feedback from the community!<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc">https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc</a> Demo GIF: <a href="https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc#demo">https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc#demo</a><p>Thanks!
