Installation

See releases.

Windows users

On Windows, you can use winget to install ClipCC.

winget install ClipTeam.ClipCC

Arch Linux users

For Arch Linux users, you can install the AUR package clipcc or clipcc-beta-bin:

yay -S clipcc

Or

yay -S clipcc-beta-bin

Note that these two packages conflict with each other.

Developer Instructions

Releasing a new version

Let's assume that you want to make a new release, version 3.999.0, corresponding to clipcc-gui version 0.1.0-prerelease.20yymmdd.

1. Merge clipcc-gui:
   1. cd clipcc-gui
   2. git pull --all --tags
   3. git checkout scratch-desktop
   4. git merge 0.1.0-prerelease.20yymmdd
   5. Resolve conflicts if necessary
   6. git tag scratch-desktop-v3.999.0
   7. git push
   8. git push --tags
2. Prep scratch-desktop:
   1. cd scratch-desktop
   2. git pull --all --tags
   3. git checkout develop
   4. npm install --save-dev 'clipcc-gui@github:clipteam/clipcc-gui#scratch-desktop-v3.999.0'
   5. git add package.json package-lock.json
   6. Make sure the app works, the diffs look reasonable, etc.
   7. git commit -m "bump clipcc-gui to scratch-desktop-v3.999.0"
   8. npm version 3.999.0
   9. git push
   10. git push --tags
3. Wait for the CI build and collect the release from the build artifacts

A note about clipcc-gui

Eventually, the scratch-desktop branch of the Scratch GUI repository will be merged with that repository's main development line. For now, though, the scratch-desktop branch holds a few changes that are necessary for the Scratch app to function correctly but are not yet merged into the main development branch. If you only intend to build or work on the scratch-desktop repository then you can ignore this, but if you intend to work on clipcc-gui as well, make sure you use the scratch-desktop branch there.

Previously it was necessary to explicitly build clipcc-gui before building scratch-desktop. This is no longer necessary and the related build scripts, such as build-gui, have been removed.

Prepare media library assets

In the scratch-desktop directory, run npm run fetch. Re-run this any time you update clipcc-gui or make any other changes which might affect the media libraries.

Run in development mode

npm start

Make a packaged build

npm run dist

Node that on macOS this will require installing various certificates.

Signing the NSIS installer (Windows, non-store)

This section is relevant only to members of the Scratch Team.

By default all Windows installers are unsigned. An APPX package for the Microsoft Store shouldn't be signed: it will be signed automatically as part of the store submission process. On the other hand, the non-Store NSIS installer should be signed.

To generate a signed NSIS installer:

1. Acquire our latest digital signing certificate and save it on your computer as a p12 file.
2. Set WIN_CSC_LINK to the path to your certificate file. For maximum compatibility I use forward slashes.
   • CMD: set WIN_CSC_LINK=C:/Users/You/Somewhere/Certificate.p12
   • PowerShell: $env:WIN_CSC_LINK = "C:/Users/You/Somewhere/Certificate.p12"
3. Set WIN_CSC_KEY_PASSWORD to the password string associated with your P12 file.
   • CMD: set WIN_CSC_KEY_PASSWORD=superSecret
   • PowerShell: $env:WIN_CSC_KEY_PASSWORD = "superSecret"
4. Build the NSIS installer only: building the APPX installer will fail if these environment variables are set.
   • npm run dist -- -w nsis

Workaround for code signing issue in macOS

Sometimes the macOS build process will result in a build which crashes on startup. If this happens, check in Console for an entry similar to this:

failed to parse entitlements for Scratch[12345]: OSUnserializeXML: syntax error near line 1

This appears to be an issue with codesign itself. Rebooting your computer and trying to build again might help. Yes, really.

See this issue for more detail: https://github.com/electron/electron-osx-sign/issues/218

Make a semi-packaged build

This will simulate a packaged build without actually packaging it: instead the files will be copied to a subdirectory of dist.

npm run dist:dir

Debugging

You can debug the renderer process by opening the Chromium development console. This should be the same keyboard shortcut as Chrome on your platform. This won't work on a packaged build.

You can debug the main process the same way as any Node.js process. I like to use Visual Studio Code with a configuration like this:

    "launch": {
        "version": "0.2.0",
        "configurations": [
            {
                "name": "Desktop",
                "type": "node",
                "request": "launch",
                "cwd": "${workspaceFolder:scratch-desktop}",
                "runtimeExecutable": "npm",
                "autoAttachChildProcesses": true,
                "runtimeArgs": ["start", "--"],
                "protocol": "inspector",
                "skipFiles": [
                    // it seems like skipFiles only reliably works with 1 entry :(
                    //"<node_internals>/**",
                    "${workspaceFolder:scratch-desktop}/node_modules/electron/dist/resources/*.asar/**"
                ],
                "sourceMaps": true,
                "timeout": 30000,
                "outputCapture": "std"
            }
        ]
    },

Resetting the Telemetry System

This application includes a telemetry system which is only active if the user opts in. When testing this system, it's sometimes helpful to reset it by deleting the telemetry.json file.

The location of this file depends on your operating system and whether or not you're running a packaged build. Running from npm start or equivalent is a non-packaged build.

In addition, macOS may store the file in one of two places depending on the OS version and a few other variables. If in doubt, I recommend removing both.

• Windows, packaged build: %APPDATA%\Scratch\telemetry.json
• Windows, non-packaged: %APPDATA%\Electron\telemetry.json
• macOS, packaged build: ~/Library/Application Support/Scratch/telemetry.json or ~/Library/Containers/edu.mit.scratch.scratch-desktop/Data/Library/Application Support/Scratch/telemetry.json
• macOS, non-packaged build: ~/Library/Application Support/Electron/telemetry.json or ~/Library/Containers/edu.mit.scratch.scratch-desktop/Data/Library/Application Support/Electron/telemetry.json

Deleting this file will:

• Remove any pending telemetry packets
• Reset the opt in/out state: the app should display the opt in/out modal on next launch
• Remove the random client UUID: the app will generate a new one on next launch
