Each alphabet contains a set of ranges and other stuff that can be either wildcard special characters or plain text. To overcome this there must be a fine way to use alphabets.

The Sigma block now provides a custom "more free" alphabet maker. But I think there must be a special range block for the Sigma

Because of the way Regulex designed it's parser we have to have a system to look for the next node and if lookahead perform both nodes together, not like this:

Back Reference block was not added to Orchestra (and causes problems: #19) because there needed to be a good design for it. Back-reference can be as simple as:

The problem here is: there is no guarantee of safety of the number. So one might suggest using options to remove the possibility of unsafe numbers:

However this is also a very bad practice as one can not determine the group numbers within a range:

Another problem here is the name groups, in the future we can support named captures as:
(<name>something) and this can also be viewed as:

So clearly there is a need for a good idea towards implementing this

Quartet is missing these special characters

• `\b' --> word boundary
• `\B' --> not word boundary
• \w --> word

On whitespace with only one element checked you get nothing:

Orchestra's Menu bar must be only visible on the macOS. On Windows and Linux the menubar will be augmented to the title less window and destroyed the whole UI.

Therefore these steps are needed:

• Disabling menubar on Windows and Linux
• Adding a Keyboard-Event Manager to handle the shortcuts without using menubar.
• Adding all the missing buttons of the menubar to the UI5's ribbon.

When I run npm install I get the following error because of macos-alias package:

npm ERR! code EBADPLATFORM
npm ERR! notsup Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})
npm ERR! notsup Valid OS:    darwin
npm ERR! notsup Valid Arch:  any
npm ERR! notsup Actual OS:   linux
npm ERR! notsup Actual Arch: x64

it's not clear how to build / run orchestra IDE
what is system dependencies and how to install them ?
how to build orchestra IDE itself ?

PS : Great job btw!

There was a bug within the views that if you were in the playground view and resized the screen, once you got back to editor you would see no editor. That happened was that when switch happens between tabs other views get to be hidden thus the resize would have no effect on Blockly. That's why the resize had to be done manually at the time of the switch:

    function onChangeWindowToEditor ( ) {
        CurrentActiveView = 'editor';
        document.getElementById( EditorWindowScreenElement ).hidden = false;
        document.getElementById( PlaygroundWindowScreenElement ).hidden = true;
        document.getElementById( TabsPlaceholder ).className = 'editor-tab';

        Blockly.fireUiEvent( window, 'resize' );
    }

FIX COMMIT

How To Build?.md has a question mark in the filename, which prevents the file being checked out from the repo. Windows does not allow filenames to contain question marks.

When I run yarn run build-linux I get the following result:

yarn run v1.3.2

That's it, it's not working, so both window.scrollTo and jump functions are broken and help page can't scroll

Introduction

RegExp Unicode Property Escapes are new parts of JavaScript RegExp tools we need to have in order to support the upcoming JavaScript editions. With this coming then we have to have two different generators for the plain text inputs in the QuartetCore that results having a transpiler like Babel and TypeScript to convert future editions of JS (ES7 or ES8 maybe) into ES5/ES6 editions in order to keep our backward-compatibility support.

Also this means that the architecture of the blocks must be configurable so that in run-time we can add or remove blocks from the toolbox for different language supports

Supporting other languages

We also have to have full compatibility with UTS18 RL1.2 in order to support other languages

Block Changes

Static blocks

The other thing to have for this big change is to have for example the Digit block be compiled to different things with or without Unicode support:

// in case of normal compile:
/\d/

// in case of Unicode in mind compile:
/\p{Decimal_Number}/u

Now thin actually means a lot. Because maybe the use is not after having the all Unicode chars matched within the context and only basic Latin ones (/[0-9]/) to be matched. This is the point where the blocks must be redesigned.

Compiler Implementation

The best option is to compile to fully ES6 RegExps and then have the code to be down-compiled to ES5 if needed with tools like RegExpU

What is not complete for the first version:

Orchestra

• About needs to be refined
• Playground needs to be fixed
  • If possible better editor (monaco really is not designed for this)
  • bigger / smaller font sizes
  • sidebar list of matches
• Ribbon supporting all buttons
  • night mode
  • window controls
• Quick Tests
• Tutorial Reference Page
• Language Reference
  • Fully refined for Orchestra 1.0 language
  • Sidebar TOC be fixed
• File format to become stable and freeze for first version
  • import only compatible files
  • having file version
• Extension Server
  • implement a right protocol for communication

Concerto

• Spaces must be fixed

Orchestra Connector

• For the first version connector must be there for the Visual Studio Code

This is what reduces:
(?:(?:<...>)) to (?:<...>)

But it has this problem:
