Language parsing
A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form (BNF). A lexer performs lexical analysis, turning text into tokens. A parser takes tokens and builds a data structure like an abstract syntax tree (AST). The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar.

I did a quick search of the issues, both open and closed, but didn't see something like what I'm proposing.
The problem I am having is that reek is throwing up warnings for scaffolding code that hasn't yet been fleshed out. I've included an example below.
I'd like a mechanism that will let me suppress all warnings for a function in the particular instance that the function is not yet impleme
Document the API
Feature Request
It would be great to include API documentation. The Usage docs are great as a walkthrough, but when you want to go fast ("what is the name for the Field
parameter for a constant value?"), API docs provide a faster answer.
Another use case: I want to inspect the __fields__
on a model, and had to read the code to get the attribute name I was looking for.

The spec in https://github.com/estree/estree/blob/master/es2020.md states
bigint property is the string representation of the BigInt value. It doesn't include the suffix n.
Should this represent the source text or a normalized notation?
In other words; is the AST for 1048575n
equivalent to that of 0xfffffn
or not due to the .bigint
field?
Tree sitter compiled with emscripten
(which I guess is currently distributed via npm
) aborts the process in case of any unhandled promise rejections.
This is very weird and not acceptable.

its either

when I run my executable and ask for help myapp.exe --help the summary gets line wrapped.
I would like for each line in my summary to have a new line between.
I have tried every mechanism to make this work to no joy (also looked in the dragonfruit code a little) but couldn't find a quick fix.

Everything in diagrams.css should be scoped to some wrapping css class, because as is it cannot be bundled with the rest of an app's css because of styles like this:
div {
-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

svg {

Curre
add a min() and max() property that shortcuts generating a list of events if possible.
If the Python Object model had a __min__()
and __max__()
this would be easier, but a min and max method is still better.
How it would work:
If the instance has a _dtstart or _until return those values instead of iterating and expanding the entire set of data.
This would be a massive speedup.

Children aren't meant to be manually managed in an array. Instead, the idea is that you should call underlying library's appendChild
and similar methods in your appendChild
.
Declaring classes and keeping track of children in arrays and then calling render
kind of goes against that because you're ignoring the valuabl

Justification
As a convenience to aid support issues, the "friendly" name of the Windows installation should be looked up from the raw version number.
Description
Currently, the RD logs OS version shows as a raw number, e.g.
Operating System: Microsoft Windows NT 6.2.9200.0 x64
Whilst this is technically correct, it's not particular

I'm copying text one tab into another to run it with another recipe. But when I change back to the first tab, the text I originally selected is no longer selected. It would be nice if this is remembered because when working with a wall of text, it's near impossible to figure out where I was.
This applies to both to input and th
