The project page for morloc, a language where you can compose functions across languages under a common type system
Here is a template Morloc app. With a few more lines, we can pass in strongly-typed, polyglot Morloc libraries. I'll make a larger demo using an Elm-like architecture soon.

morloc: a workflow language for multi-lingual programming under a common type system
A conventional scientific workflow consists of many applications with untyped data flowing between them. Each application builds an internal data structure from input files, performs an operation, and...

Release #morloc v0.58.2! Now docstrings can specify how CLIs are generated. Arguments may be optional and have defaults. Records can be translated to groups of arguments.

Release #morloc v0.58.2! Now docstrings can specify how CLIs are generated. Arguments may be optional and have defaults. Records can be translated to groups of arguments.
The new #morloc getter and setter patterns are the most radical of the new changes in v0.57.1. They offer a succinct syntax for generating functions that access or update data. They replace the many little helper functions #morloc previously required. Here are a few examples:

*multi-line strings* allow triple-quotes to enclose strings that span multiple lines and automatically trims whitespace. See example below where the trimmed whitespace is highlighted:

*string interpolation* allows #morloc expressions to be substituted into strings. Currently the behavior is quite minimal and works only for expressions that evaluate to strings. In the future more formatting options will be added.

*placeholder syntax* allows expressions with underscores to be translated into lambas expression. For example:
![Show the expression `map (sub _ 1) [1,2,3]` which produces [0,1,2] and the expression `map (_,42) [1,2,3]` which generates the list of tuples [(1,42),(2,42),(3,42)].](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:2oih2zkmhzgfvx6ox2bnauv7/bafkreibkgl5sdpkhh5ubez6v6zym4ladmbehj5hi2erjnrsjag4zv3xp44@jpeg)

Releasing Morloc version 0.57.1! There are 5 major new features: placeholder syntax, string interpolation, multi-line strings, and getter and setter patterns. I'll introduce all of each of these in dedicated posts.

#morloc meetup this Saturday and Tuesday are canceled, we'll resume the week after. I've been under the rocks trying to fix Morloc's language selection algorithm -- brain's too fried to English.
Also, I've been thinking about strongly typed functional programming and AI. #hackathon #foreshadowing

Meetup tomorrow at 5pm ET (Aug 19). I'll introduce the install manager, review the composable CLI tools from last week and demo a FASTQ trimmer.
I'd also like to hear your thoughts on what #morloc would need for you to use it in your workplace.
See you on discord: t.co/PBu4CyrvZe

Almost got the #Treesitter grammar working!

Just needs a little cleaning and testing. Next I can do a little PR to GitHub and then will finally have colors in my repo code. This also can be used in editors like Zed and Neovim.

🌟 Huge thanks to everyone who joined the first virtual #morloc #hackathon yesterday!
We spent the day beta-testing the Morloc language, smoothing out install issues and running our first programs together.
🚀 Morloc execution is now tested on Linux, MacOS, and Windows (via WSL)!

Sharing the #morloc language! Compose functions across languages under a common type system. In #bioinformatics, build better workflows by switching from the file/application-based paradigm to a native function paradigm. Looking for adventurous first adopters!
