SILE v0.10.15 Is Released

02 Mar 2021 — Caleb Maclennan

Version v0.10.15 of SILE has been released and is available for download! See the included CHANGELOG.md or review the commit history for more explicit details.

Summary of Improvements

This release fixes a couple of regressions and adds a couple small features. On the regression front, access to the interactive prompt has been restored and the table of contents metadata in PDFs is properly encoded again. For new features, COLR fonts are now automatically detected and the necessary support package is loaded when they are used, a new package allows spaces to be drawn using font-provided glyphs rather than assuming empty space, and another new package allows access to OpenType font features through more verbose fontspec names rather than their OpenType feature code names.

Features

  • fonts: Allow for code to be run when a font is first loaded (bdf05ab)
  • packages: Add \font-feature command (e2cf008)
  • packages: Add complex-spaces package (#1148) (b7451ae)

Bug Fixes

  • cli: Re-enable access to repl, input argument not required (a6434ee)

  • core: Allow builtin Lua bitwise operators on Lua 5.4 (5f0c2c7)

  • docker: Switch to BuildKit and make Docker Hub cooperate (783b104)

  • docker: Use patched glibc to work around outdated hosts (fa2532c)

  • docker: Use patched glibc to work around outdated hosts (#1141) (bf74417)

  • docker: Work around libtexpdf build having side effects (33510d9)

  • packages: Add CharacterVariant to features (929eca2)

  • utilities: Correct UTF-8/UTF-16 conversions (4863ed6)

SILE v0.10.14 Is Released

03 Feb 2021 — Caleb Maclennan

Version v0.10.14 of SILE has been released and is available for download! See the included CHANGELOG.md or review the commit history for more explicit details.

Summary of Improvements

This release introduces a new dependency on an external Lua UTF-8 string handling library. By introducing proper string handling instead of our home grown functions we knocked out several bugs including invalid encoding in the output when error tracing was turned on. We also added some (ironically, home grown) UTF-16 string handling to sanitize output of Font meta data.

Features

  • core: Make luautf8 library available in global scope (ab7e745)

Bug Fixes

  • build: Run autoupdate to fix autoconf issues (ab8307b)

  • core: Decode UTF-16BE strings in Windows platform name entries (e7662f8)

  • debug: Use UTF8 safe substring function in trace stack (495a5bf)

  • manual: Small error (d738b62)

SILE v0.10.13 Is Released

30 Nov 2020 — Caleb Maclennan

Version v0.10.13 of SILE has been released and is available for download! See the included CHANGELOG.md or review the commit history for more explicit details.

Summary of Improvements

This release brings a few bug fixes, most notably unscrambling Arabic (and some other complex script) shaping. Since current work in process includes significant changes to the document class API and these fixes have been sitting around for a while I figured it was time to give them a release number before anything potentially more disruptive lands.

Feature-wise the only significant improvement is complete coverage for all element types in the Pandoc document AST, enabling any converted documents to compile without errors. They might not be pretty out of the box yet, but at least they render and can be styled by adding or modifying commands.

Features

  • classes: Allow footnotes in plain class if package loaded (42c1ceb)
  • classes: Run deferred package init() on late load (0224fe3)

Bug Fixes

  • backends: Add complex shaping data to debug backend (a1a6509)

  • backends: Don't crash if debug output precedes regular (19c21f2)

  • build: Don't abuse libtool internals (for NetBSD packaging) (#1084) (048c8b5)

  • classes: Define \strong weight=700, not 600 (#1097) (68abf91)

  • packages: Add default options to simpletable (1f10c97)

  • packages: Correct math operations on grid spacing (5286188)

  • packages: Turn off complex flag for items in \latin-in-tate (b20690f)

SILE v0.10.12 Is Released

10 Oct 2020 — Caleb Maclennan

Version v0.10.12 of SILE has been released and is available for download! See the included CHANGELOG.md or review the commit history for more explicit details.

Summary of Improvements

This release fixes just two bugs. The simpler of the stops custom styles in verbatim blocks. Much more urgently, a backend fix correctly accounts for offsets calculated during the shaping process and stops resetting the PDF cursor position. This issue primarily broke Arabic, but typesetting any fonts with cursive positioning or mark placement rules were affected.

Bug Fixes

SILE v0.10.11 Is Released

25 Sep 2020 — Caleb Maclennan

Version v0.10.11 of SILE has been released and is available for download! See the included CHANGELOG.md or review the commit history for more explicit details.

Summary of Improvements

This release supports versions of Lua Penlight newer than 1.8.0. Previous releases of Penlight have contained a long-standing bug in the class inheritance system that we were side-stepping with our own workaround. In one case our workaround was actually relying on a side-effect of said Penlight bug and never should have worked. With a proper fix finally implemented in Penlight, our workaround started to fail. This release includes an emergency patch so that SILE can be made to work on systems with the latest Penlight release. Future releases will likely remove our workarounds entirely and require a recent version of Penlight with the fixed class inheritance system.

Additionally, this is the first release that officially supports running SILE as a GitHub Action. You can now call SILE directly in CI workflows on your own projects.

Other cleanup work now allows classes to specify their own framesets without inheriting the default ones. This has no visible effect for most documents but it does make debugging framesets a lot easier because there aren’t a bunch of empty frames behind the scenes inherited from other classes.

With special thanks to contributions from Fredrick Brennan, SVG support is much improved in this release. Specifically, shapes with holes now actually render as holes. Also, thanks to Johannes Maibaum’s contributions and careful eye, many examples from the manual which had fallen behind or had typos now actually work as documented.

Features

  • actions: Add configuration file to run as GitHub Action (ee2d509)
  • backends: Modify setCursor() to handle relative movements (7caa9c8)
  • classes: Make it possible to not use parent class framesets (99b9f50)
  • cli: Add Lua interpreter info to --version (bf5210d)

Bug Fixes

  • backends: Properly switch between normal and debug fonts (b53896e)
  • classes: Identify triglot class as triglot not diglot (495654a)
  • classes: Make declareFrames() workable by passing ids (27b6b4a)
  • classes: Move class setup code into deferred class:init() (6f470d7)
  • core: Patch Penlight 1.9.0 compatibility issue (1eb4290)
  • packages: Allow Hanmen frame creation to use optional ID arg (7853d5a)
  • packages: Fix hole drawing from svg in PDF (6521fd0)
  • packages: Remove extra space in \code in url (b90cd37), closes #1056
  • tooling: Expand variables so fonts are known dependencies of tests (88ac888)

Performance Improvements

  • backends: Reuse variables instead of recalculating values (02cce40)
