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.

A few questions regarding the language
Not that I've ever seen personally. They mostly exist as extensions in various places. Gforth has one, for example.

What forth implementation could be a good pick for writing a texteditor?
I don't know the status of gforth's 'minos2' offering but I see a mention of X11 which is a promising sight for Linux GUI work.

Aro: A C compiler written in Zig
For contrast, gforth (a prominent Forth interpreter, by Forth standards) generates+compiles+links binding code in C, at runtime, using the ordinary C toolchain. [0][1][2]
A bit 'out there' you may say, but on the plus side this approach enables handling header files and tidily expressing bindings without the need to implement their own C parser. [2]

which forth do you guys use for normal day to day scripting and programming
I use SP-Forth (production), Gforth (testing).

A Forth Indirectthreaded Pcode Vms Performance On
Gforth has to take special steps to ensure the OS doesn't prevent the transfer of control over to the dynamically generation instruction sequence.

x-in-y lines - Succintly written (<1000 non-obfuscated loc), fully-functional software in any language.
almost all my codes in https://github.com/phreda4/r3 and https://github.com/phreda4/r4 have less 1000 lines, but all forth have code with minimun lines of code

r4 Forth
Looking here I think they've made the decision to go with the MIT licence.

Share cool Forth programs!
I wrote many programs in r4 (32 bits windows).. see in https://github.com/phreda4/r4

r4 is for 32bit https://github.com/phreda4/r4

Looking for a simple forth compiler (producing asm/executables, not compiling forth words) to learn from, preferably in C family language
I have a vm in c for my forth, I have a compiler to asm (generate FASM output) but in the same lenguage, really a forth compiler is a simple program, there are a 1:1 correspondence in code genaration and words. here the 32bits source https://github.com/phreda4/r4/blob/master/r4/System/r4i86.txt here the 64bits with some optimizations: https://github.com/phreda4/r3d4/blob/master/r3/sys/r3asm0.r3 I hope this help
