Added

  • TOC (Table of Contents) navigation is now enabled
    • #498, #511
    • TOC box generation is enabled when #b= Viewer parameter (= Viewer.loadPublication() function) is used, and the publication has TOC data. In HTML documents, TOC is marked up with e.g. <nav role="doc-toc">. Vivliostyle recognizes element that is selected with CSS selector [role=doc-toc], [role=directory], nav li, .toc, #toc as a TOC element.
    • [Viewer UI] vivliostyle/vivliostyle-ui#62
  • Support Web Publications and similar multi-HTML documents
    • #511
    • Supported document types with #b= Viewer parameter (= Viewer.loadPublication() function):
      • Unzipped EPUB
        • URL of the OPF file can be specified as well as the top directory of the unzipped EPUB files.
      • Web publication (a collection of HTML documents with reading order)
      • (X)HTML document
        • When (X)HTML document URL is specified, the URL is treated as primary entry page's, and a series of HTML files are automatically loaded.
          • When the web publication manifest is specified in the primary entry page (X)HTML document, the readingOrder in the manifest is used.
          • If manifest is not specified or "readingOrder" is not in the manifest, the (X)HTML documents linked from the TOC element that is selected with CSS selector [role=doc-toc], [role=directory], nav li, .toc, #toc are loaded.
  • Support loading documents from GitHub and some specific URLs
    • #499, #505, https://github.com/vivliostyle/vivliostyle.js/commit/3424d965
    • GitHub and Gist URLs can be directly specified. Vivliostyle loads raw github/gist content when github/gist URL is specified.
    • Aozorabunko (青空文庫) (X)HTML URL can be specified. Vivliostyle loads Aozorabunko's raw github content when Aozorabunko (X)HTML URL is specified.
    • JS Bin URL is converted to JS Bin output URL and can be loaded. This is useful for testing Vivliostyle output from small HTML + CSS code, as well as Gist.
  • Publication title and individual HTML document title are now passed to viewer UI
  • env(pub-title) and env(doc-title) environment variables for page headers with publication/document titles
    • #512
    • Spec: CSS Environment Variables Module Level 1 defines env() function, but env(pub-title) and env(doc-title) are not yet defined so far.
    • env(pub-title): publication title = EPUB, Web publication, or primary entry page HTML title. Enabled when #b= Viewer parameter (= Viewer.loadPublication() function) is used.
    • env(doc-title): document title = HTML title, which may be chapter or section title in a publication composed of multiple HTML documents
    • When title data are not found, i.e. no <title> element in HTML, or env(pub-title) with #x= Viewer parameter (= Viewer.loadDocument() function), the empty string "" is returned.
  • Viewport-percentage length units: vw, vh, vi, vb, vmin, vmax, and page-size-percentage units pvw, pvh, pvi, pvb, pvmin, pvmax
    • #507
    • Spec: CSS Values and Units - Viewport-percentage lengths, but page-size-percentage units are not defined so far.
    • Note: On paged media context, the viewport-percentage units vw, vh, vi, vb, vmin, vmax are relative to the size of the page area, i.e., the content area of a page box and not including margin, border and padding specified on @page rule. This makes a lot of sense, but page size relative units may also be necessary. The pvw, pvh, pvi, pvb, pvmin, pvmax units are similar to the vw, vh, vi, vb, vmin, vmax but the reference size is the page size including page margins.
  • Support CSS calc() function
  • [Viewer UI] New "User Style Preferences" in the Settings panel

  • [Viewer UI] Vivliostyle Viewer start page with document URL input and usage description
    • vivliostyle/vivliostyle-ui#65
    • When document URL parameter (#b= or #x=) is not specified, the start page is now displayed.
    • Document URL entered by user is reflected in the URL parameter #b=, and 　 when the Enter key is pressed, the document is loaded.

    • Spec: CSS Fragmentation Module Level 3
    • Note that the current implementation treats all values of break-inside other than auto as the same as avoid. The fine-grained control (distinguishing avoid, avoid-page, avoid-column and avoid-region) will be a future task and tracked with a separate issue.
    • Note that though the spec requires to honor multiple break-before/break-after values at a single break point, the current implementation choose one of them and discard the others. The fine-grained control of these break values will be a future task and tracked with a separate issue.

0.1.1 - 2015-05-06

Minor update with several changes and bug fixes.

Added

Changed

  • [core] Cascade page size specified in @page rules to page masters defined by @-epubx-page-master rules
    • #17
    • When @page rules and @-epubx-page-master rules are both specified, the page size specified by 'size' property in @page rules is applied to the selected page master. This behavior is not defined in the related specs. We added this behavior for a use case in which one wants to print content styled with Adaptive Layout on a paper sheet and wants to specify the sheet size by adding a (user) stylesheet containing @page rules with 'size' property.

Fixed

0.1.0 - 2015-04-28

Initial alpha release. Following features are added while keeping the original Adaptive Layout features.

Added

  • [viewer] Support spread view mode
    • #7
    • The spread view can be enabled by adding '&spread=true' to the end of the viewer URL.
    • Note: Page size calculation is incorrect when content with 'auto' page size is viewed in the spread view mode. This problem will be fixed in the next release.
  • [viewer] Added page navigation buttons
