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.

Creating a compiler in Java
There are a few different tool-sets for producing Java byte code. I'm not sure which one to suggest, because back when I last needed one (end of '96), there were none, so I wrote my own. But I assume that most people use ASM or something similar.

Microfeatures I'd like to see in more languages
This is one that I like a lot. Years ago (1997 timeframe) I had implemented it in a Java compiler, and a few years later in a Java library (https://github.com/oracle/coherence/blob/4e6e343e1ffd9bbfea3...) that would create an exception on the assertion failure and parse its stack trace to find the source code file name, and read it to find the text of the assertion that failed, etc. so it could build the error message ...
In Ecstasy, we built the support directly into the compiler again:

What's going on behind type type declaration?
For the debugger (but not required by the runtime), there is an optional table that points to the ranges of ops at which names and types are bound to registers
-
Resources to understand code generation from AST?
FWIW - here's an AST for Java that directly emits Java byte code: https://github.com/oracle/coherence/tree/master/prj/coherence-core/src/main/java/com/tangosol/dev/compiler/java

Why text only.
It has been "experimented with" many times. Here's an example from TDE, a component-based development environment from Tangosol (now part of Oracle).

Anybody have tips for writing a Recursive Descent Parser for an AST? [ JS ]
If it helps, here's a Java recursive descent parser that I wrote years ago.
-
A new kind of scope?
If you want to see an example, here's a Context interface from a multi-language compiler framework (compiling multiple different languages to Java byte-code) that I wrote years ago.

Are Functional Programming Languages the best option for Crafting a Compiler?
I built an entire Java compiler in four months, from scratch, by myself, over twenty years ago. (Now owned by Oracle; still used today. Thank you, Larry.) But starting from a well written spec for a simple language like Java is orders of magnitude easier than developing a new language, runtime model, and tool-chain from scratch.

How to build an AST with a list of Tokens? (Recursive Descent)
As mentioned, the various parsing methods each contribute back an AST node, so on the way down the recursion, they are parsing, and on the way back up from the recursion, they are building the tree. Here's a fairly simple recursive descent Java compiler written in Java that I wrote a few years back, in case you are looking for an example.
-
Do these examples belong to syntax or semantics and are they handled by syntactic or semantic analysis?
If you're curious how some of this can be implemented in a Java compiler, I wrote one years ago. For example, checking that the left side is an l-value:

ChipWits (1984) was programmed in MacFORTH because...
I recently found a little C-like scripting language, S-Lang (aka slang) that is a stack machine that allows some explicit stack manipulation. This almost feels like programming directly in Java VM byte codes or FORTH. Not for the faint of heart.

The S-Lang programming library is a software library for Unix, Windows, VMS, OS/2, and Mac OS X. It provides routines for embedding an interpreter for the S-Lang scripting language, and components to facilitate the creation of text-based applications.[3] The latter class of functions include routines for constructing and manipulating keymaps, an interactive line-editing facility, and both low- and high-level screen/terminal management functions. It is distributed under the terms of the GNU General Public License.
