check out [InjectJS](https://github.com/quoid/InjectJS).** - -## Usage - -**Version 2 and above requires Safari 13+** - -As of Version 2.0.0, this extension now supports multiple, domain specific, userscripts as well as supporting 2 different "userscript" types. It supports traditional javascript userscripts as well and css "userscripts" (or more commonly referred to as, userstyles). - -Click the extension's toolbar button to open the extension UI. - -**If you don't feel like reading, view [this markdown file](/etc/gifs.md) to watch some short agif tutorials.** - -**UI Overview** -![Userscripts Safari](/etc/ui-overview-01.png) -![Userscripts Safari](/etc/ui-overview-02.png) - -1. **Create New Userscript Button** - Click this button to create a new userscript. You will be able to choose what type of userscript you would like to create (css or js) -1. **Userscript Filter** - You can use this to filter through your existing userscript. **Note**, this element filters by userscript title, not desription. It supports the following flags to help you filter more efficiently: `!js`, `!css`, `!disabled`, `!enabled` -1. **Userscript Toggle** - Toggling this element with enable/disable it's injection into webpages -1. **Editor** - The editor; the place where you write the code for the userscripts -1. **Download Button** - Click this to download a copy of your userscript -1. **Delete Button** - Click this to delete the userscript; *note:* deleted userscripts get put into your trash bin -1. **Settings Button** - Click this to open the settings modal -1. **Status Info** - Look here for status message pertaining to the currently opened userscript -1. **Discard/Save Buttons** - After editing a userscript, clicking on the "discard" button will remove any changes made since the userscript was loaded; clicking on the "save" button will save your changes to the userscript -1. **Sidebar** - Newly added/created scripts go here -1. **Settings Modal** - The various settings for the extension -1. **Global Blacklist** - Domain patterns entered here will be excluded from userscript injection; adding `*://*.*` to the global blacklist will turn off injection for all userscripts - -## Userscript Metadata - -Version 2.0.0 introduces the common practice of using userscript metadata to drive certain functionality. The currently supported fields will be listed below. There *are* plans to support more fields in future updates. - -- `@name` - This will be the name that displays in the sidebar and be used as the filename - you can not use the same name for multiple scripts of the same type -- `@description`- Use this to describe what your userscript does - this will be displayed in the sidebar - there is a setting to hide userscript descriptions -- `@match` - Domain match patterns - you can use several instances of this field if you'd like multiple domain matches - view [this article for more information on constructing patterns](https://developer.chrome.com/extensions/match_patterns) -- `@exclude-match` - Domain patterns where you do *not* want the script to run -- `@include` - An alias for `@match` - functions exactly like `@match` -- `@exclude` - An alias for `@exclude-match` - functions exactly like `@exclude-match` -- `@inject-into` - allows the user to choose which context to inject the script into - - allows the user to choose which context to inject the script into - - values: auto, content, page (default) - - works like [violentmonkey](https://violentmonkey.github.io/api/metadata-block/#inject-into) -- `@run-at` - - allows the user to choose the injection timing - - document-start, document-end (default), document-idle - - works like [violentmonkey](https://violentmonkey.github.io/api/metadata-block/#run-at) -- `@weight` - - allows the user to further adjust script injection timing - - can be used to ensure one script injects before another - - ONLY accepts integers (floats, strings and everything else will be ignored) - - min value = 1, max value = 999, higher numbers (“heavier”) execute earlier - -**All userscripts need at least 1 `@match` or `@include` to run!** - -CSS Userscripts/styles can use the javascript metadata format or the Userstyle format. Both formats shown below are valid for **css** type. - -```js -// ==UserScript== -// @name Example -// @description An example -// @match *://github.com/* -// @match *://*.github.com/* -// ==/UserScript== -``` - -```css -/* ==UserStyle== -@name Example -@description An example -@match *://github.com/* -@match *://*.github.com/* -==/UserStyle== */ -``` - -## Userscript Save Location - -See how it is done [here](/etc/gifs.md#change-save-location). - -As of v2.1.0, the user can choose where their userscripts are saved to and loaded from. There's no api that allows this change to happen from the extension, so users must perform location changes from the host application. - -In order to change the location, you must either launch `Userscripts.app` as you would any other application, or open the settings modal within the browser extension and click the "settings" icon within the "Save location" row. - -Once the host app is open, you will see a button called "Change save location". Click this and select the directory where you'd like to save to/load from. - -**Save Location Notes** - -- Close all instances of the extension UI (browser app) before you change the save location. The extension will attempt to do this automatically, but it could fail (if it does, please bug report) - -- Currently, when changing the save location, the app does not copy over userscripts from the previous save/load directory - -- After a new save location is selected, if you rename or move that selected folder, the extension will continue to load/save to that location - the only way to remove the “link” is by trashing the folder or selecting a new save location - -## Notes & FAQs - -**Do I need to use the extension's editor to create new userscripts or to edit existing?** - -No; simply put your userscript in the extension's scripts folder. You can easily access this folder by clicking the link in the extension's settings modal option labelled "Save Location" or by visiting `~/Library/Containers/com.userscripts.macos.Userscripts-Extension/Data/Documents/scripts/`. - -If you are adding a new userscript, before injection will occur, you must open the extension UI by clicking on the extension's toolbar button. If you are editing an existing userscript through your own editor, you should not need to open the ui for the changes to take effect. - -**Can I change the location where my files are saved?** - -Not yet, but this is planned in a future update. - -**Are there any keyboard shortcuts?** - -Currently there is only one keyboard shortcut - `cmd+s` to save changes. *Note:* normal shortcuts like `cmd+z`, `cmd+shift+z`, etc... like you would have on any other normal webpage should still function. - -**I updated from Version 1.5.0, where did my previous userscript go?** - -Your previous userscript file *should* still exist after update. You can access its folder by clicking the link in the extension's settings modal option labelled "Save Location" or by visiting `~/Library/Containers/com.userscripts.macos.Userscripts-Extension/Data/Documents/`. - -**How can I help development** - -One of the best ways you can help development is to **[sign up to be a beta tester](https://forms.gle/QB46uYQHVyCxULue9)**. You will be able to test new features before they are released and help guide development by providing essential feedback. - -Another great way you can help out is by **[leaving a review for the app on the App Store](https://itunes.apple.com/us/app/userscripts/id1463298887)**. - -Further, any issue marked "help wanted" is actively seeking assistance. Please respond to those issues with feedback, guidance or offer coding assistance. Outside of those issues, it is fair to assume outstanding issues are already being worked on and new features are being actively developed. - -## Feedback & Support -If you need help doing something with this extension or you have an idea for an enhancement, please open an issue. Be sure to search current and closed issues before opening a new one. - -## Donate - -## Privacy Policy -Userscripts does not collect any data from its users nor monitor activities or actions you perform within the application and extension. This means everything that you do with the application and extension is private to you and is never shared with the developers or third parties. Since there is no data collection, there is no data retention of any kind. +Version 3 Information ## License diff --git a/gulpfile.js b/gulpfile.js index a7cee40f..1d5c2e44 100644 --- a/gulpfile.js +++ b/gulpfile.js @@ -1,169 +1,49 @@ -const { dest, parallel, series, src, watch } = require("gulp"); -const atImport = require("postcss-import"); -const autoprefixer = require("autoprefixer"); -const connect = require("gulp-connect"); +const {dest, series, src} = require("gulp"); const del = require("del"); -const htmlmin = require("gulp-htmlmin"); const inline = require("gulp-inline-source"); -const nunjucksRender = require("gulp-nunjucks-render"); const postcss = require("gulp-postcss"); -const sourcemaps = require("gulp-sourcemaps"); - -const sourcePath = "./src"; -let outputPath = "./build"; - - -function clean() { - if (process.env.NODE_ENV === "production") { - outputPath = "./extension/Userscripts Extension"; - return del(`${outputPath}/index.html`); - } else if (process.env.NODE_ENV === "demo") { - outputPath = "./demo"; - return del(`${outputPath}/**/*`); - } else { - // delete all files at the output path, except .gitignore - return del(`${outputPath}/**/*`); - } -} - -function css() { - // NODE_ENV production is set when using the "npm run build" command - // if NODE_ENV === production, no sourcemaps and minify the css - const path = `${sourcePath}/stylesheets/_main.css`; - - // autoprefix more browsers for demo page - var browsers = ["safari 13"]; - if (process.env.NODE_ENV === "demo") { - browsers = ["last 4 version"]; - } - - if ( - process.env.NODE_ENV != "production" - || process.env.NODE_ENV != "demo" - ) { - return src(path) - .pipe(sourcemaps.init()) - .pipe(postcss([ - atImport(), - autoprefixer({overrideBrowserslist: browsers}) - ])) - .pipe(sourcemaps.write()) - .pipe(dest(outputPath)); - } else { - return src(path) - .pipe(postcss([ - atImport(), - autoprefixer({overrideBrowserslist: browsers}) - ])) - .pipe(dest(outputPath)); - } -} +const autoprefixer = require("autoprefixer"); +const htmlmin = require("gulp-html-minifier-terser"); -function js() { - // not much is done to the JS files, they simply copied over - // they will be inlined in the html function, if doing a build/demo - return src(`${sourcePath}/js/**/*.js`) - .pipe(dest(`${outputPath}/js/`)); +// will be building from a clone of the public directory +// if not for this, the global stylesheets would get prefixed which are used in development +function copy() { + return src("./public/**/*") + .pipe(dest("./temp")); } -function lib() { - // not much is done to lib files, other than copying them over - // and inlining on build/demo - return src(`${sourcePath}/lib/**/*`) - .pipe(dest(`${outputPath}/lib/`)); +// autoprefix select stylesheets and overwrite in place +function autoprefix() { + return src(["./temp/build/bundle.css", "./temp/css/global.css"]) + .pipe(postcss([ + autoprefixer({overrideBrowserslist: ["last 4 version"]}) + ])) + .pipe(dest(file => file.base)); } -function html() { - // set a var for whether or not we are in dev/demo mode - // development var will be false when running the npm run build command - // during development we will NOT inline css or js files - // that way we can properly debug - // on builds everything will inlined to a single html file and minified - let demo = false; - let development = true; - let ignore = ["css", "js"]; - if ( - process.env.NODE_ENV === "production" - || process.env.NODE_ENV === "demo" - ) { - development = false; - ignore = []; - } - if (process.env.NODE_ENV === "demo") { - demo = true; - } - return src(`${sourcePath}/index.html`) - .pipe(nunjucksRender({ - // pass custom data to nunjucks for use throughout template(s) - // these are using in index.html to determine what to inline - data: { - demo: demo, - development: development - }, - path: [ - `${sourcePath}/macros`, - `${sourcePath}/partials` - ] - })) +// conditionally inline dev.js if bundling a demo page based on env var set in package.json +// inline the rest of the asset for a monolithic html file +function bundle() { + const d = process.env.NODE_ENV === "demo" ?
