Show HN: Codigo – The Programming Language Repository

https://codigolangs.com
78•adamjhf•1mo ago
Codigo is a site I've built for discovering, exploring and comparing programming languages, including language news, trends and code examples.

I couldn't find any definitive resource for finding new languages and comparing them, so decided to make one.

It combines dynamic data from sources like PyPL Index, TIOBE Index and official feeds as well as static data about each language defined in a structured format. The language data is open-contribution and can be updated by anyone on the GitHub repository: https://github.com/codigo-langs/codigo.

I styled it specifically for coders - using a monospaced font and terminal-esque styling, along with many common IDE themes to choose from.

Codigo is built using Rust, Axum, HTMX and Alpine.js.

Keen to hear any feedback!

Why is the C++ example for 100 doors 10,000x over-complicated compared to the C version?

Is this a sick joke?

benatkin•1mo ago
It gets the last one, maybe it would be better if it got the first one: https://rosettacode.org/wiki/100_doors#C
philocalyst•1mo ago
Wondering if you would be interested in plugging into my

https://github.com/philocalyst/lang-config

Which contains comment tokens, block and line, common language servers, special pairs, recognized shebangs, root scopes, etc.

It's mostly for use in one of my other projects, although you can see some of its higher aspirations one day in the README. Would love to collaborate with you and make it useful for a real use-case outside my own! If any of the information contained there could be useful! Reach out through an issue or through an email (linked in my github profile) if you're keen

I’m interested in a list of new open-source programming languages released in the last 5, 3, and 1 years - ideally organized by category. Does such a list exist anywhere?

EDIT: minimal wikidata version: https://w.wiki/E5e3

genewitch•1mo ago
How? Just a bunch of volunteers? Make a wiki-like and let people edit it, show HN, and maybe eventually PL makers will add their PL to your database.

Even if you scrape Wikipedia, or stack overflow or whatever, you're going to miss the newest and also the esoteric and possibly even wider use stuff. Basically you can't do it alone.

My life is a series of "why doesn't this exist? Oh, what a gigantic pain in the ass. That's why it doesn't exist. God bless anyone who makes this, because it ain't gunna be me" situations. I hope someone has done what you are looking for.

pella•1mo ago
I have created a minimal wikidata query https://w.wiki/E5e3

  SELECT ?language ?languageLabel ?inceptionDate 
         (GROUP_CONCAT(DISTINCT ?website; SEPARATOR=", ") AS ?websites)
         (GROUP_CONCAT(DISTINCT ?developerLabel; SEPARATOR=", ") AS ?developers)
         (GROUP_CONCAT(DISTINCT ?paradigmLabel; SEPARATOR=", ") AS ?paradigms)
  WHERE {
    # Find items that are either programming languages or types of programming languages
    {
      ?language wdt:P31 wd:Q9143 .  # programming language
    } UNION {
      ?language wdt:P31 wd:Q116481801 .  # type of programming language
    }
    
    # Get the inception date
    ?language wdt:P571 ?inceptionDate .
    
    # Filter for languages created within the last 10 years
    FILTER(?inceptionDate >= "2009-05-12"^^xsd:dateTime)
    
    # Optional properties to get more information
    OPTIONAL { ?language wdt:P856 ?website . }  # official website
    OPTIONAL { 
      ?language wdt:P178 ?developer . 
      ?developer rdfs:label ?developerLabel .
      FILTER(lang(?developerLabel) = "en")
    }  # developer
    OPTIONAL { 
      ?language wdt:P3966 ?paradigm . 
      ?paradigm rdfs:label ?paradigmLabel .
      FILTER(lang(?paradigmLabel) = "en")
    }  # programming paradigm
    
    ?language rdfs:label ?languageLabel .
    FILTER(lang(?languageLabel) = "en")
  }
  GROUP BY ?language ?languageLabel ?inceptionDate
  ORDER BY DESC(?inceptionDate)  # Sort by date, newest first
  LIMIT 100
genewitch•1mo ago
It's a good start, and i can't think of missing items off-hand, and i didn't know you could do that. I've done queries like this on the wiki sql itself locally, but i didn't know there was a notebook interface to querying like that.
pella•1mo ago
I’m glad to see there’s a substantial metadata system powering the portal (and even minimal Wikidata integration + CC0-1.0 license! )

This is the Julia: https://github.com/codigo-langs/codigo/blob/master/languages...

I assume the initial database was built on Wikidata plus a lot of data cleaning. Is the code for the Wikidata synchronization available anywhere? I can’t seem to find it in the repo.

One thing you could add is a free-form wiki-style description field, where you could even embed an "awesome" list for each language, for example: https://github.com/coderonion/awesome-julia-list

adamjhf•1mo ago
Yes, some initial data was scraped from Wikidata, but there is no synchronisation. For reference, I've added the Wikidata queries here: https://github.com/codigo-langs/codigo/tree/master/scripts/w...

Good idea on including awesome lists! I'll take a look at that.

worldsayshi•1mo ago
Would be interesting to see which languages a language has influenced in addition to which influenced it.
blami•1mo ago
Great job! Would be lovely to have filters on when language was created. Also one minor nit, I am not super mouse oriented person and wanted to bookmark the site but ctrl+d is mapped to scroll down.
adamjhf•1mo ago
Thanks for raising that. I've changed that key mapping now to a less common one to avoid conflicts.
tgv•1mo ago
You might want to add some relation between the versions of Ada. Each is basically a superset of the previous version. You could treat them as one, and specify per feature from which version onward it is part of the language, e.g. https://www.adaic.org/advantages/ada-comp-chart
adamjhf•1mo ago
Yes, at the moment it’s just a flat listing of languages. Will think about how to solve for dialects etc. without making it overly complex.
cranberryturkey•1mo ago
how do I add https://smashlang.com?
adamjhf•1mo ago
New languages can be added by adding a relevant YAML file to https://github.com/codigo-langs/codigo/tree/master/languages, following the defined schema.

If you change the theme, sometimes the theme dropdown shows white text on a white background.

e.g. on chrome / Ubuntu, change theme to material or nord-dark, then dropdown is all white (shows if you hover the items)

Same if you go to a programming language page, the drop down for code examples is white on white

adamjhf•1mo ago
Thanks for flagging. This is hopefully fixed now.
WillAdams•1mo ago
How are you defining "programming language"?

TeX is listed: https://codigolangs.com/language/TeX

but OpenSCAD is not.

anentropic•1mo ago
What is it?
elviejo•1mo ago
You can also look at pldb.com It has a huge list of programming languages and its attributes.
aredox•1mo ago
