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.

PoE's Filters aren't fancy, so I fixed that. I'm proud to announce PoeFilterX, my new Advanced PoE Filter Tool!
While I do like projects like this in this case I think I like the way filter spirit solved it more. I can do something like:
-
Introducing the Future of Item Filters - PoE Dynamic Loot Filter
This looks like a great collection of ideas, many of which I have already implemented in my own filter-generating tool (which compared to yours is more advanced on the internal feature side but has basic CLI + terrible UI). I think we could collaborate to create something together (I could already mention many possible features - poe.ninja-based generation, filter template description language, color/strictness presets). I have large amounts of notes from working with filters (many not published on my github project).

Significant bug within item filters - invisible items under certain Continue statements

- Filter Spirit - write filters with enhanced syntax. Compile filter templates. Use variables, poe.ninja data and more!

Fixing Left and Mutual Recursions in Grammars
Debugging a complex PEG is a nightmarish task. I use various tools, but I couldn't find anything out there that will let you set a breakpoint in a file that's being parsed and let you explore the parsing state.
The most useful tools I found were adjacent to the cpp-peglib library: https://github.com/yhirose/cpp-peglib
This comes with a PEG playground: https://yhirose.github.io/cpp-peglib/
I really liked pegdebug: https://mqnc.github.io/pegdebug/
With sample output here: https://mqnc.github.io/pegdebug/example/output.html
pegdebug is nice for small sets of data, but it rapidly gets swamped by anything over about 50 lines.
If anyone has other suggestions for debugging PEGs, please reply and let me know,.

I used yhirose's PEG (parsing expression grammar) libraryfor parsing.

What are some cool modern libraries you enjoy using?
By the same author, https://github.com/yhirose/cpp-peglib is also very nice.

A Good Tool for Resuming Parsers?
Most of the research into this sort of incremental and differential parsing unsurprisingly looks to be in the Haskell community, but I was hoping that someone here might know of some C++-friendly tools that might support generating parsers that support interruption and resuming. cpp-peglib looked really promising, but its parsers don't look like they can be engaged from any but the initial state.
- yhirose/cpp-peglib - A single file C++ header-only PEG (Parsing Expression Grammars) library
What are some alternatives?
parsergen - Self-hosted parser/scanner generator from LR grammar with semantic annotations in C++20
PEGTL - Parsing Expression Grammar Template Library
spirit - Boost.org spirit module
ctpg - Compile Time Parser Generator is a C++ single header library which takes a language description as a C++ code and turns it into a LR1 table parser with a deterministic finite automaton lexical analyzer, all in compile time.
mewa - Compiler-compiler for writing compiler frontends with Lua
scope_guard - A modern C++ scope guard that is easy to use but hard to misuse.
