Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Why should I care wether my shell is POSIX compliant?
If we're detaching from POSIX, why not get more wild? Why not xonsh or something? Also I found this lua inspired shell which could be cool: https://github.com/hush-shell/hush

Working with JSON in traditional and next-gen shells like Elvish, NGS, Nushell, Oil, PowerShell and even old-school Bash and Windows Command Prompt
Maybe hush (https://github.com/hush-shell/hush) should be included in this list.

Guide: Hush Shell-Scripting Language
While being extremely small is a worthy goal, I suppose the aim of Hush is to make writing larger shell scripts easier and less error-prone. It's more for the niche of Perl of old than of minimal shells like ash.
For a very limited device, a very limited shell like that in Busybox is sufficient, because it likely does not need large shell scripts, or a lot of interactive work.
Looking at [1], current Hush is under 700k, which is still way smaller than Python or Perl, with much of its expressiveness.

If you're not using a lexer generator for your compiler, why?
Yes, you can check the code here: https://github.com/gahag/hush

Visual Basic for Applications Language Specification [pdf]
Perhaps the one from ANTLR's collection [0] is a good start (there are also others ANTLR VB6 grammars documented elsewhere). It does require knowing ANTLR, but that should be less effort for someone already familiar with language implementation, particularly, the visitor pattern (my favorite reference [1]).

Postgres Language Server: Implementing the Parser
Where is the SQLite test suite, please? I'd be very interested.
There are already SQL grammars, check https://github.com/antlr/grammars-v4 specifically in here I think https://github.com/antlr/grammars-v4/tree/master/sql I contributed to one of them, and I wrote my own for some personal work. Be warned, it's very involved, very complex and MSSQL is rather ill-defined.
Names bracket identifiers) in SQL are bloody awful. Sometimes square brackets are even compulsory, and why you can usually replace [...] with the SQL standard "..." , not always! Trust me, it gets worse.
I don't find antlr grammars to be brittle, and while they can lose in performance (by how much I don't know, perhaps quite considerably) they are very easy to maintain and I am very fortunate to have antlr to work with.

Llama: Add Grammar-Based Sampling
This grammar "library" was cited as an example of what the format could look like:.
https://github.com/antlr/grammars-v4
There is everything from assembly and C++ to glsl and scripting languages, arithmetic, games, and other weird formats.

Structured Output from LLMs (Without Reprompting!)
> Which brings me to the other approach: steering the LLM's output __as it is generating tokens__
A relevant PR:
https://github.com/ggerganov/llama.cpp/pull/1773
The plan is to support arbitrary grammar files to constrain tokens as they are generated, like the ones here:
https://github.com/antlr/grammars-v4

SQL-Parsing
Have a look at jooq - I know this has been used to rewrite SQL from one dialect to another, so it MUST be capable of collating code activity metrics. Look here. Otherwise, you might want to look into writing your own parser. ANTLR has a T-SQL dialect parser script here.

How should I prepare for AI-driven changes in the industry as a Software Engineering Manager
Find a Perl grammar file for ANTLR, like https://github.com/antlr/grammars-v4/tree/master/perl Save the grammar file as Perl.g4 in your project. Now, you can create the Kotlin program: import org.antlr.v4.runtime.* import org.antlr.v4.runtime.tree.ParseTree import java.io.File
- Can you create a cpp file in a program like you could a txt file?

DELD: An experimental HTTP-Client
Antlr is another option. You could generate a parser using the JSON antlr grammar.
- Are there any resources available to convert a code from Basic to C++? need to do this for the sake of an assignment. anything will be helpful
