Markdown Math

Build

I'll assume the myscript version is 2.0.1.

Download MyScriptInteractiveInk-Runtime-iOS and unzip at the project root.

Place ingun.markdown-math.c that is sent you by email under MyCertificate/ folder.

The version is fixed to 2.0.1 in the ci_scripts/ci_post_clone.sh script.

Linting

# install
brew install swiftlint

# run
swiftlint --fix --strict markdown-math/*.swift

How to run MyScript Examples on your iPad

Change the sample's bundle identifier to ingun.markdown-math.
Copy the contents of /MyCertificate/ingun.markdown-math.c and paste to .../MyCertificate.c

Implement MyScript Demo

Download sample from myscript/interactive-ink-examples-ios.

Import Demo and Frameworks to project. Choose Create groups when adding the folders.

Make some changes.

Header search path

Add ${SRCROOT}/Frameworks or wherever the Frameworks folder is to Header Search Paths as recursive.

Remove conflicting project data

Remove Demo/Supporting Files/ and Demo/Classe/Utils/AppDelegate.swift and Demo/MyCertificate/

Change Prev and Next to Cancel and Done

In Main.storyboard, change the Prev and Next at the bottom toolbar to Cancel and Done by setting System Item. Remove + button.

In MainViewModel, set default value of previousButtonEnabled and nextButtonEnabled to true. It has to remain true and never change so search for all their usages and delete.

Remove + button at the bottom toolbar and addPartBarButtonItem and their usages from MainViewController.

Notify Done and Cancel

In EditorWorker.swift, Call MyScriptSampleObserver.done(tex: String) and MyScriptSampleObserver.cancel() from func loadNextPart() and func loadPreviousPart() respectively.

    func loadNextPart() {
        if let editor = self.editor,
           let part = editor.part{
            let type = part.type
            editor.waitForIdle() // Waits until part modification operations are over.
            if let aaa = try? editor.export(selection: editor.rootBlock,
                                        mimeType: IINKMimeType.laTeX
            ) {
                MyScriptSampleObserver.shared().delegate?.done(tex: aaa)
            }
        }
    }

    func loadPreviousPart() {
        MyScriptSampleObserver.shared().delegate?.cancel()
    }

Import LaTex to editor

In MainViewModel, append following code to didLoadPart()

    func didLoadPart(title: String, index: Int, partCount: Int) {
        // ...
        if let editor = self.editor, let tex = MyScriptSampleObserver.shared().latex {
            try? editor.import(mimeType: IINKMimeType.laTeX, data: tex, selection: editor.rootBlock)
        }
    }

Bundle Resources

Go to project setting > Build Phases > Copy Bundle Resources and add .../recognition-assets as folder.

Remove all the individual files under recognition-assets added by adding Demo folder before.

Import Swift into ObjC

In SmartGuideViewController.mm, change Swift module import header to #import "markdown_math-Swift.h"

Remevo redundant UI components

In Demo/Clasess/Scenes/Main.storyboard, remove Navigation Item > Right Bar Button Items > More Bar Button Item.

In Demo/Classes/Scenes/Toolbar/Toolbar.storyboard, remove Highlighter, Style, and Lasso button.
