2018-07-08 22:39:46 -07:00
Brett Zamir 9f65b1adb9 - Breaking change: Extension now formatted as export (and `this` is set to editor, including for `callback`)
- Breaking change: Locale now formatted as export
- Breaking change: Moved out remaining modular i18n (imagelib) to own folder
- Breaking change: Drop `executeAfterLoads` (and getJSPDF/getCanvg)
- Breaking change: `RGBColor` must accept `new`
- Breaking change: canvg - `stackBlurCanvasRGBA` must be set now by function (`setStackBlurCanvasRGBA`) rather than global; `canvg` now a named export
- Breaking change: Avoid passing `canvg`/`buildCanvgCallback` to extensions (have them import)
- Fix: i18nize imaglib more deeply
- Fix: Positioning of Document Properties dialog (Fixes #246)
- Fix (regression): PDF Export (Fixes #249)
- Fix (regression): Add polyfill for `ChildNode`/`ParentNode` (and use further)

- Refactoring( RGBColor) `RGBColor` as class, without rebuilding constants, optimize string replacement, move methods to prototype, use templates and object literals, use `Object.keys`
- Refactoring (canvg) Use classes more internally, use shorthand objects; array extras, return to lazy-loading
- Refactoring: Use Promises in place of `$.getScript`; always return Promises in case deciding to await resolving
- Refactoring: Avoid importing `RGBColor` into `svgutils.js` (jsPDF imports it itself)
- Refactoring: Arrow functions, destructuring, shorter property references
- Refactoring: Fix `lang` and `dir` for locales (though not in use currently anyways)
- Refactoring: Provide path config for canvg, jspdf
2018-06-12 06:50:28 +08:00
Brett Zamir 8c9e40d349 - Breaking change: Rename config file to `svgedit-config-iife.js` (or for the module version, `svgedit-config-es.js`);
also expect one directory higher; incorporates #207 (@iuyiuy)
- Breaking change: Separate `extIconsPath` from `extPath` (not copying over icons)
- Breaking change: Don't reference `custom.css` in HTML; can instead be referenced in JavaScript through
    the config file (provided in `svgedit-config-sample-iife.js`/`svgedit-config-sample-es.js` as `svgedit-custom.css` for
    better namespacing); incorporates #207 (@iuyiuy)
- Breaking change: Remove minified jgraduate/spinbtn files (minified within Rollup routine)
- Fix: Zoom when scrolled; incorporates #169 (@AndrolGenhald), adapting for conventions; also allow avoidance when shift key pressed
- Fix: Update Atom feed reference in HTML
- Fixes related to recent commits: Some path and method name fixes needed, function order, missing methods, variable scope declaration, no need for DOMContentLoaded listeners in modules, switch back to non-default export, avoid trimming nullish, deal with mock tests, fix `math.matrixMultiply`, use jquery-svg where needed for array/SVG attributes; add babel-polyfill and defer script to imagelib; other misc. fixes
- Enhancement: Move config-sample.js out of `editor` directory
- Enhancement: For `callback`-style extensions, also provide config object; add following
   to that object: buildCanvgCallback, canvg, decode64, encode64, executeAfterLoads, getTypeMap, isChrome, ieIE, NS, text2xml
- Enhancement: Complete ES6 modules work (extensions, locales, tests), along with Babel;
    make Node build routine for converting modular source to non-modular,
    use `loadStylesheets` for modular stylehsheet defining (but parallel loading);
- Enhancement: Add `stylesheets` config for modular but parallel stylesheet loading with `@default` option for simple inclusion/exclusion of defaults (if not going with default).
- Refactoring: Clean up `svg-editor.html`: consistent indents; avoid extra lbs, avoid long lines
- Refactoring: Avoid embedded API adding inline JavaScript listener
- Refactoring: Move layers and context code to `draw.js`
- Refactoring: Move `pathActions` from `svgcanvas.js` (though preserve aliases to these methods on `canvas`) and `convertPath` from `svgutils.js` to `path.js`
- Refactoring: Move `getStrokedBBox` from `svgcanvas.js` (while keeping an alias) to `svgutils.js` (as `getStrokedBBoxDefaultVisible` to avoid conflict with existing)

- Testing: Update QUnit to 2.6.1 (node_modules) and Sinon to 5.0.8 (and add sinon-test at 2.1.3) and enforce eslint-plugin-qunit linting rules; update custom extensions
- Testing: Add node-static for automating (and accessing out-of-directory contents)
- Testing: Avoid HTML attributes for styling
- Testing: Add npm `test` script
- Testing: Comment out unused jQuery SVG test
- Testing: Add test1 and svgutils_performance_test to all tests page
- Testing: Due apparently to Path having not been a formal class, the test was calling it without `new`; refactored now with sufficient mock data to take into account it is a class
- npm: Update devDeps
- npm: Add html modules and config build to test script
2018-05-25 20:03:14 +08:00
Brett Zamir ae2394f086 (INCOMPLETE: ES6 Module conversion and linting)
- Breaking change: Require `new` with `EmbeddedSVGEdit` (allows us to use `class` internally)
- Breaking change: If `svgcanvas.setUiStrings` must now be called if not using editor in order
    to get strings (for sake of i18n) (and if using path.js alone, must also have its `setUiStrings` called)
- Breaking change (ext-overview-window): Avoid global `overviewWindowGlobals`
- Breaking change (ext-imagelib): Change to object-based encoding for namespacing of
    messages (though keep stringifying/parsing ourselves until we remove IE9 support)
- Breaking change: Rename `jquery.js` to `jquery.min.js`
- Breaking change: Remove `scoped` attribute from `style`; it is now deprecated and
    obsolete; also move to head (after other stylesheets)
- Enhancement: Make SpinButton plugin independent of SVGEdit via
    generic state object for tool_scale
- Enhancement: Remove now unused Python l10n scripts (#238)
- Enhancement: ES6 Modules (including jQuery plugins but not jQuery)

- Enhancement (Optimization): Compress images using imageoptim (and add
    npm script) (per #215)
- Fix: i18nize path.js strings and canvas notifications
- Fix: Attempt i18n for ext-markers
- Refactoring (ext-storage): Move locale info to own file imported by the extension (toward modularity; still should be split into separate files by language and *dynamically* imported, but we'll wait for better `import` support to refactor this)
- Refactoring: For imagelib, add local jQuery copy (using old 1.4.4 as had
    been using from server)
- Refactoring: For MathJax, add local copy (using old 2.3 as had been using from
    server); server had not been working
- Refactoring: Remove `use strict` (implicit in modules)
- Refactoring: Remove trailing whitespace, fix some code within comments
- Refactoring: Expect `jQuery` global rather than `$` for better modularity
    (also to adapt line later once available via `import`)
- Refactoring: Prefer `const` (and then `let`)
- Refactoring: Add block scope keywords closer to first block in which they appear
- Refactoring: Use ES6 `class`
- Refactoring `$.isArray` -> `Array.isArray` and avoid some other jQuery core methods
    with simple VanillaJS replacements
- Refactoring: Use abbreviated object property syntax
- Refactoring: Object destructuring
- Refactoring: Remove `uiStrings` contents in svg-editor.js (obtains from locale)
- Refactoring: Add favicon to embedded API file
- Refactoring: Use arrow functions for brief functions (incomplete)
- Refactoring: Use `Array.prototype.includes`/`String.prototype.includes`;
    `String.prototype.startsWith`, `String.prototype.trim`
- Refactoring: Remove now unnecessary svgutils do/while resetting of variables
- Refactoring: Use shorthand methods for object literals (avoid ": function")
- Refactoring: Avoid quoting object property keys where unnecessary
- Refactoring: Just do truthy/falsey check for lengths in place of comparison to 0
- Refactoring (Testing): Avoid jQuery usage within most test files (defer script,
    also in preparation for future switch to ES6 modules for tests)
- Refactoring: Make jpicker variable declaration indent bearable
- Refactoring (Linting): Finish svgcanvas.js
- Docs: Mention in comment no longer an entry file as before
- Docs: Migrate old config, extensions, and FAQ docs
- Licensing: Indicate MIT is license type of rgbcolor; rename/add license file name for
    jgraduate and screencast to reflect type (Apache 2.0); rename file to reflect it
    contains license information (of type MIT) for Raphael icons

- Fix: `addBezierCurve` in canvg.js had undeclared `i`
- Fix: Undeclared variable in opera widget
- Fix: Screencast `showNotes`
