Introducing ASF: An Open-Source Scripting Framework Embedded in VBA for Microsoft Office Automation

Hey r/opensource!

I'm excited to share ASF (Advanced Scripting Framework), a pure VBA-based noscripting language and runtime that turns Microsoft Office apps like Excel into dynamic noscript hosts. ASF embeds a C-like DSL with features like first-class functions, shared-write closures, array/object literals, and functional methods (map, filter, reduce, etc.), all while integrating seamlessly with VBA via FFI and VBA-Expressions for advanced math/stats/finance computations.

Why open-source? ASF started as a hobby extension to VBA-Expressions but evolved into a full framework after a year of development, passing 85+ unit tests for reliability. It's MIT-licensed, with the goal of fostering a community around modernizing VBA without external dependencies. Whether you're building sandboxed macros, custom DSLs, or data pipelines, ASF makes it easy and safe.

Key highlights:

- Syntax: Imperative control flow (if/else, for/while, switch, try/catch) + functional patterns.
- Expressivity: Nested/recursive array ops, e.g., a.map(fun(o){return {k: o.k*2, arr: o.arr.map(fun(x){return x+1})};});.
- Interop: Bridge to call custom native VBA functions directly.

Repo: https://github.com/ECP-Solutions/ASF (v1.0.3 released with docs, tests, and examples).

We welcome contributions—bug fixes, new methods, or tests! If you're into evolving VBA or Office dev, check it out and star/fork. Feedback appreciated!

Laid off looking for routine

Hi, I was recently laid off from Amazon. I understand why this happened to me and Im on my way to interview prep.

The thing is I dont know how to switch from a routine of working on a project with a team to working by yourself on leetcode (with possibly no end in sight).

Is there an open source project which I can treat as my work and collaborate with it's devs? Im looking for a community that discusses sho is working on what and have milestones.

What are the most intimidating parts of building an open source app?

I've built 2 open source apps in the past. It was a lot more challenging than I thought going in. I'm working on a framework to make building them easier.

As the noscript says, I'm curious what was hard about the process or what's intimidating / scary if you've never built one? It could be anything from design, implementation and auth to distributing and sharing your work online. It could also just be things like being nervous about security or not knowing how to do something. Interested in any and all experiences!

Why is it important to divide libraries into sub-libraries?

I've been creating open source libraries for quite some time. In the beginning, I thought it was cool to create a large library with cool features. However, over time, I realized that this approach has a lot of problems:

\- I began to notice that I began to want to reuse many pieces of one project in other libraries. What should I do then, copy the code? It's a bad idea.

\- Over time, the boundaries of abstractions begin to "blur" due to the growing size of the project.

\- Promoting 1 large library is much more difficult than 20 small ones. Creating one large library is one touch of the audience, and 20 libraries is 20 touches. Each touch is like buying a lottery ticket, and the more of them, the easier it is to "win" the audience's attention.

\- The quality of the code in a large repository will inevitably be lower. The larger the project, the more difficult it is to maintain consistently high quality across the entire code base and contain the growth of technical debt.

These and many other problems were solved when I started splitting my large libraries into several small ones. What do you think about this? What is your experience?

LibreWeddingPlanner; completely free and open source tool for managing guests, overseeing expenses, and other important aspects of planning your wedding!

I stumbled across this project on the Fediverse recently, and because the people who build it don't have a Reddit account, I figured I'd spread the good word myself!

**LibreWeddingPlanner** is an AGPL-Licensed, self-hostable platform for—you guessed it—planning a wedding! It functions as a potential alternative to something like TheKnot. The cutest thing about it is that it was, according to their Mastodon account, built because one of the devs wanted a F/LOSS tool to plan their own wedding, which is super sweet! If you don't want to self-host, you can also use their own instance.

All development happens on Codeberg, where their git repo is hosted: https://codeberg.org/LibreWeddingPlanner/ (and if you don't know about Codeberg, it's a community-funded alternative to GitHub, powered by the F/LOSS git forge software, Forgejo!)

On top of that, they have a social media profile on the Fediverse, as previously mentioned, and this is their profile: https://ruby.social/@libreweddingplanner (You can just search for @libreweddingplanner@ruby.social from your own instance and find them that way, too!)

From what I can tell, they currently do not have a way to donate, so the best we can all do to support this new alternative to proprietary software is to spread the word! Which is precisely what I'm doing, lol.

If any of y'all end up using it yourselves, 1.) Congratulations on the big day! and 2.) Do be sure to let the devs know about what you thought; they're very active on Fedi and seem to be very hopeful to improve the project.

Windows 10 revert from 11

Not sure how to tag this for flair or if I can get help here but thought it couldn’t hurt. We have specific namesake programs we use at our business and the programs will not work on windows 11. (Those companies are working on a fix for windows 11 but it won’t be for a few months) So instead of losing money from being without said programs that contain printable products to sell I need to revert a Windows 11 laptop back to windows 10. This wasn’t done recently so there’s not a backup still in windows before the upgrade.

So far my solution has been to create a bootable windows 10 usb using Rufus and backing up files to upload later once on 10 again. I guess my question is there an easier way to do this? I understand I won’t have support on windows 10 but this computer only has one use for us so not worried about that.

Lenovo Laptop x64 Currently on Windows 11 Pro.

Help, my project is taking off!

First off, I know this is complaining on a high level. But this is a situation I haven't had before and I don't know how to handle it.

I made a OSH physiotherapy game console for kids with chronic illnesses that require daily inhalation and breathing physiotherapy. I designed the hardware, I made the OS, I made games that can be loaded from SD card in an app-like system.

I primarily made this for one of my kids who has such a chronic illness.

I then put it on github, including the source code, the 3D print files and a detailed denoscription of how to make it. And then crickets. Nobody really cared about it.

Until I talked to the head of a local self-help group for that kind of illness, and she really started pushing the project. Two hospitals use that device now together with a few kids who use it at home. None of them wanted to build it themselves (even though it's quite simple) and I had to manufacture them.

Now one of the hospitals wants to make a paper on that game console and they ordered 30pcs from me, which is awesome, but at that volume I have to find a way to tax all this, might have to get certifications and all that, and now it's much more stressful than just the hobby thing I did for my kid. They also want some software changes to work with the stuff they need for the paper. The kids are asking for more games that I now have to make.

It's just not fun any more and it's becoming more and more of a chore.

Right now I wish I could just hand off the project to someone else, but there's no one else. As almost always open sourcing doesn't mean that anyone is contributing.

How do I deal with stuff like that?

I made a visual grid that shows your subnoscriptions sized by how much they actually cost you

Hey everyone! I built a simple tool that turns my subnoscriptions into a proportional treemap - bigger box = bigger monthly spend.

Seeing it visually was honestly a bit confronting. I knew streaming services cost money, but I didn't realize they made up quite a lot of my total subnoscription spend until I saw them as massive boxs. Made it pretty easy to decide what to cut first.

What it does:

Shows all your subnoscriptions as proportional boxes
Instantly highlights which services dominate your budget
Useful for deciding what's actually worth keeping vs what to cancel

Privacy-focused:

No signup required
100% free (personal project, I make nothing from this)
All data stays in your browser - nothing sent anywhere

Try it here: visualize.nguyenvu.dev
Source code: hoangvu12/subgrid

Would love feedback, is this actually useful, or am I the only one who needed to see it visually to take action? Open to suggestions on what would make it better.
