0.12.0 (2021-09-22)


  • packages: Previous to this release footnote and folio frames took their font settings from a new typesetter with default settings. With this release the settings are now derived from the typesetter in the default frame, hence inheriting font family, size, leading, and other settings. Values can still be set using the same functions, but relative values such as font sizes are based on a different base.

0.11.1 (2021-09-03)

Bug Fixes

  • build: Avoid implied line continuation in makefile (f2af48f)
  • build: Require Git even building tarballs, used by package manager (aba8662)
  • languages: Update deprecated syntax in language options (3fb1719)

0.11.0 (2021-09-01)


  • packages: Previous to this release any and all leading between paragraphs (as set with document.parskip) –even a 0 height skip– would result in the skip of one full empty grid space — as if parskip had been set to something approximating a full line height. This change corrects the calculation so if a 0 height skip is added and everything fits, the next line or paragraph will continue uninterrupted in the next grid slot. To get the previous layout behavior back, document.parskip must be explicitly set to be something larger than 0. Even a minimal 1pt skip will result in paragraph spacing that includes one full grid height left blank as before:


  • utilities: Previous return value for breadcrumbs:contains() was just an depth index with -1 indicating no match. This made sense when I wrote it, but coming back to it for a new project I expected a boolean return value. Returning two values seems like the best option, but given the function naming it seemed to make sense to return the boolean first, hence the API breakage.

0.10.0 (2020-01-13)


  • This removes the auto-guessing file extension mechanism that allowed *.sil files to be loaded without specifying the full file name with extensions. A command like sile test will no longer find and build sile.sil, you must run sile test.sil. The mechanism that was doing this was a hack than only worked in some scenarios anyway, and dropping it instead of trying to cover all the edge cases will make it that much easier to use and document. Importantly it avoids edge cases where both *.xml, *.sil, and/or *.lua files all have the same name and the loader really has so idea which one you mean.

Note that packages may still be loaded with no file extension, this does not affect the require() mechanism that looks for *.lua and various other incantations by default.

No code changes, but the previous release was broken due to extraneous files in the tarball. Oh, the embarrassment.

0.9.5 (2019-01-07)

  • Experimental package manager.

  • The "smart" bare percent unit (where SILE guessed whether you meant height or width) has now moved from deprecated to error. Replace with %pw etc.

  • Language support: variable spaces in Amharic (and other languages if enabled with the shaper.variablespaces setting), improvements to Japanese Ruby processing, Uyghur hyphenation revisited and improved, Armenian hyphenation added.

  • You can now set the stretch and shrink values of a space using the shaper.spaceenlargementfactor, shaper.spaceshrinkfactor and shaper.spacestretchfactor settings.

  • You can use - as input filename to pipe in from standard input, and - as output filename to pipe generated PDF to standard output.

  • New letter class.

  • New commands: \neverindent and \cr

  • New units: ps (parskip) and bs (baselineskip)

  • Links generated via the url package are hyperlinked in the PDF.

  • You can now style folios (page numbers) by overriding the \foliostyle macro.

  • Languages may define their own counting functions by providing a counter function; you may also lean on ICU's number formatting to format numbers.

  • ICU is now required for correct Unicode processing.

  • Experimental support for SVG graphics and fonts. (see tests/simplesvg.sil)

  • Users may select the Harfbuzz subshaping system used (coretext, graphite, fallback etc.) by setting the harfbuzz.subshapers setting.

  • Fix typos in documentation (Thanks to Sean Leather, David Rowe).

Most other changes in this release are internal and non-user-visible, including:

  • Introduced vertical kern nodes.

  • Various fixes to pushback (end of page) logic, bidi implementation. ICU is now used for bidi.

  • Updated various examples to work with current internals.

  • Many and varied internal fixes and speedups, and improved coding style.

0.9.4 (2016-08-31)

Nearly 600 changes, including:

  • New packages include: letter spacing, multiple line spacing methods, Japanese Ruby, font specimen generator, crop marks, font fallback, set PDF background color.

  • Fixed handling of font weight and style.

  • Hyphenation: Correct hyphenation of Indic scripts, words with non-alphabetic characters in them, and allow setting hyphen character and defining hyphenation exceptions.

  • Relative dimensions ("1.2em") are converted to absolute dimensions at point of use, not point of declaration. So you can set linespacing to 1.2em, change font size, and it'll still work.

  • Default paper size to A4.

  • Changes to semantics of percent-of-page and percent-of-frame length specifications. (width=50% etc.)

  • Much improved handling of footnotes, especially in multicolumn layouts.

  • Support for: the libthai line breaking library, color fonts, querying the system font library on OS X, multiple Amharic justification conventions.

  • Added explicit kern nodes.

  • Changed to using Harfbuzz for the text processing pipeline; much faster, and much more accurate text shaping.

  • Rewritten and more accurate bidirectional handling.

  • Removed dependency on FreeType; use Harfbuzz for font metrics.

  • Fixed the definition of an em. (It's not the width of a letter "m".)

and much more besides.

0.9.3 (2015-10-09)

  • Support for typesetting Japanese according to the JIS X 4051 standard, both horizontally and vertically.

  • Unicode line-breaking support; scripts now line-break correctly even if they don't have specific language support. Optionally uses the ICU library if installed.

  • Font designers rejoice: you can now say \font[filename=...] to use uninstalled fonts.

  • Pango/Cairo support is now officially deprecated. Stop using it!

  • Improvements to USX Bible processing.

  • Experimental support for Structured PDF generation.

  • Support for Opentype kerning.

  • Support for custom frame direction (e.g. "TTB-LTR" for Mongolian).

  • Support for many-way parallel texts across pages or spreads.

  • Line breaking support for Myanmar, Javanese and Uyghur.

  • Support for boustrophedon Greek. No, really.

  • Various fixes to bidirectionality, discretionary hyphens, insertions, footnotes, grid typesetting, alignment.

  • Under-the-hood advancements for Harfbuzz.

0.9.2 (2015-06-02)

  • New packages for: rotated content, accessing OpenType features and ligatures, alternative input of Unicode characters, PDF bookmarks and links, input transformation.

  • Packages to help with typesetting chord sheets and bibles.

  • Experimental packages for bibliography management, typesetting URLs, Japanese vertical typesetting, balanced columns, and best-fit page breaking.

  • Support for quoted strings in the parameters to TeX-like commands.

  • Language support: Many fixes to Arabic; support for Tibetan and Kannada; hyphenation for many languages; much improved bidirectional typesetting.

  • Warn when frames are overfull.

  • Support for older versions of autotools, for Lua 5.3 and mingw32 environments.

  • Continuous integration and testing framework

  • Fixes to long-standing bugs in grid support, centering, ligatures, insertions and page breaking.

  • Better font handling and substitution.

  • Valid PDFs will still be generated on error/interruption.

  • Improved error handling and error messages.

  • Many miscellaneous bug fixes.

0.9.1 (2014-10-30)

  • The main change in this release is a new shaper based on Harfbuzz and a new PDF creation engine. This has greatly improved the output quality on Linux, as well as bringing support for multilingual typesetting and allowing future support of interesting PDF features. (It's also much faster.)

  • The new PDF library also allows images to be embedded in many different formats, rather than just PNG.

  • Documents can now be written in right-to-left languages such as Hebrew or Arabic, and it's possible to mix left-to-right and right-to-left text arbitrarily. (Using the Unicode Bidirectional Algorithm.)

  • Initial support for languages such as Japanese which have different word/line breaking rules.

  • Frames can be grouped into a set called a "master", and masters can be used to set the frame layout of a given page.

  • Hopefully a much easier installation process, by bundling some of the required Lua modules and using the standard autoconf ./configure; make strategy.

  • Support for Lua 5.2.
