Change History -------------- 2020-08-31 luaotfload v3.15 * The font database is updated more reliably if fonts get deleted. * In multiple error cases, error messages are shown instead of silently generating bad output. * Write glyph ids instead of internal identifiers to DVI files. This allows using OpenType fonts when working with dvilualatex. (This requires additional support from the DVI reader) * The set of font features which are enabled by default has been changed to be more similar to HarfBuzz. Especially Above-base mark Positioning (abvm), Below-base mark Positioning (blwm), Contextual Alternates (calt), Cursive Positioning (curs), Distances (dist), and Required Contextual Alternates (rclt) are now enabled by default for all scripts. * Added a mathfontdimen font feature which allows emulating fontdimen values from xetex or traditional \TeX\ math fonts. * Initial support for variable fonts in node mode. 2020-05-01 luaotfload v3.14 * bug fix for luaotfload-tool, luaotfload-tool --list=basename failed (texlive list) * fontloader patched to resolve issue #124 2020-05-01 luaotfload v3.13 * A problem with text fonts with minimal math table has been fixed (issue 148.) In new luaotfload versions, math parameters will only be loaded for fonts with `script=math`. If you do want to set math parameters for fonts with other scripts, add `-nomathparam`. We strongly recommend against setting math parameters for text fonts because these would overwrite parameters from actual math fonts. * A bug in harf-mode that could lead to missing chars and freezing was corrected (issue 141). * A font size problem in harf-mode has been fixed (issue 147). * An error if the main function was called twice has been fixed (issue 145). * Allow .ttf fonts to be loaded with a map file with luahbtex (issue 142) (issue 143). * Fonts installed for a single user on windows are now found (issue 138). * A problem with wrong \TeX-ligatures in harf mode has been fixed (issue 139). * The debugging output has been changed (issue 131). * a missing U+1E9E (Capital ß) in a font is replaced by SS instead of giving a missing character. * extended the color handling to be compatible with the luacolor package * sync with context files from 2020-04-30 2020-02-02 luaotfload v3.12 * new experimental feature multiscript * new experimental feature fallback * extension of the color feature to color output glyphs * Small bug correction 2019-11-10 luaotfload v3.11 * Changed the handling of the script key in harf mode to be more compatible with behaviour of the node mode. It now expects the name of a script that is actually in the font instead of a ISO 15924 script tag. See issue 117. * Corrected a number of small typos and bugs in harf mode. 2019-11-04 luaotfload v3.1 * added code to use the harfbuzz library of luahbtex ("mode=harf") * fonts in ttc can now be indexed by name * remove a number of lua tables from the global enviroment (_G) to reduce the polution. Kept there are only the tables luaotfload, fonts and nodes. * sync with context files from 2019-10-29 2019-09-13 luaotfload v3.0 * invisible option to avoid that some glyph are shown (issue #63) * correct small bug in xheight calculation 2019-08-11 luaotfload v2.99 * some clean up * fix a bug in luaotfload.aux.resolve_fontname() (issue #76) * removed dependency on slnunicode (PR#72) * sync with context files from 2019-08-11 2019-06-20 luaotfload v2.98 * add embolden key * add missing char detection issue #65 * sync with context files from 2019-07-04 2019-05-18 luaotfload v2.97 * fix issue #47 * fix whatsits interfering with letterspacing (issue #53) * fix luaotfload-tool switches version and find not working correctly (PR#59) * fix luaotfload-tool support of ttc fonts (PR#58) * sync with context files from 2019-05-18 (improves handling of large fonts, see e.g. issue #55 and PR#58) 2019-01-28 luaotfload v2.96 * repaired broken letterspace (issue #38) * changed handling of spaces in letterspacing * changed handling of ligatures in letterspacing * corrected detection of bold fonts (issue #41) 2019-01-28 luaotfload v2.95 * imported context files of 2019-01-28 * changed bold indification (for lucida demi bold) (issue #33) * changed handling of tex file (issue #35) * changed resolver code (pr #36) 2019-01-14 luaotfload v2.94 * imported context files of 2018-12-19 * removed luaotfload-characters from init - use the basics-chr instead. * allow custom fontloaders through the mode-key https://github.com/u-fischer/luaotfload/pull/25 * resolved issue #29 2018-10-28 luaotfload v2.93 * reinserted forgotten man files * unified and improved version/module info for automatic tagging 2018-10-21 luaotfload v2.92 * better deva support, issue #9 * test for --safer and abort, issue #12 * newest context files * correct file: syntax for tfm files, issue #11. 2018-10-03 luaotfload v2.91 * solved copy & paste of variant glyphs, https://tex.stackexchange.com/questions/451442/localized-glyphs-locl-have-unicode-value-ufffd * solved problem with PUA no longer accessible with \char, see https://github.com/u-fischer/luaotfload/issues/7 2018-09-21 luaotfload v2.9 * added various testfiles for the l3build system/travis tests to the github repository * solved a bug regarding directions https://github.com/u-fischer/lua-font-pond/issues/12 * adapted luaotfload-letterspace to new fontloader * solved the case problem see https://github.com/u-fischer/lua-font-pond/issues/6 * Fix parsing of font.conf see https://github.com/lualatex/luaotfload/pull/420 * imported new versions of the context files - fontloader is compatible with luatex 1.08 again * adapted the files list * created a luaotfload-filelist.lua which describes the files of the package * removed some not functional files * adapted mkstatus to use the new file list. 2017-01-29, luaotfload v2.8: * Latest fontloader code. * Support for Luatex 1.0. * Integration of the extended AFM handler. * Fixes to font family assignment. * Skip initialization if Luaotfload is already loaded. * Optical sizes advertised by fonts treated as big points. 2016/04/21, luaotfload v2.7: * Rework lookup chaining. * Combining glyphs from different fonts (``combo: ...`` requests). * Glyph fallbacks. * Latest fontloader code. * Adapt packaging to changed upstream file layout. * Remove support for builtin Fontforge libraries (this includes the PFA, PFB, DFONT, and feature file readers). * Allow configuration of anonymous lookups. 2015/12/09, luaotfload v2.6 * Add ``sign`` target to makefile for automated package signing. * Add ``--dumpconf`` option to luaotfload-tool for generating configuration files. * Move fontloader files to subtree src/fontloader. * New script ``mkimport`` facilitates maintainance of code imported from Context. * Revised letterspacing, now utilizing the ``node.direct`` interface. * Revized colorization of fonts, utilizing ``node.direct`` (Dohyun Kim). * Colorization was moved to the ``post_linebreak_filter`` stage. * Move remaining functionality from ``luaotfload-override`` into initialization. * Write names index if fonts were removed. * Separate module loading from initialization. * Custom fontloader package with the files from Lualibs removed. * Swappable fontloader via configuration option. * Lualibs are now a dependency when used in a TeX run as well. * Respect interword spaces when letterspacing. 2014/07/13, luaotfload v2.5 * Remove legacy code. * Remove compatibility with the old mkluatexfontdb script. * Remove test directory. Use https://bitbucket.org/phg/lua-la-tex-tests instead. * Remove luaotfload.lua from luaotfload.dtx; it is now a separate file luaotfload-main.lua. * Standard source tree structure: the code is now located in the ./doc, ./scripts, ./src, ./build, and ./misc directories. * Move the heavier LPEG parsers from luaotfload-features (syntax) and luaotfload-database (fontconfig) into the new file luaotfload-parsers.lua. * Move logging routines from luaotfload-override in to luaotfload-log. * Scan local font files (``--local`` flag to luaotfload-tool, flag ``scan_local`` during TeX run). * Add bisection mode (``--bisect``) to luaotfload-tool. * Add functions for accessing the database: ``aux.font_index()`` and ``aux.read_font_index()``. * Distinguish XDG configuration paths (Reuben Thomas) * Optional configuration via rc files. * Configure default features via configuration file. 2013/12/31, luaotfload v2.4 * Additional self-tests, now in separate file (luaotfload-diagnostics.lua) * Better path and directory handling, especially on Windows * database now indexes Type1 fonts (PFA, PFB) and makes them accessible with style modifiers (requires --format=+pfa,pfb option to luaotfload-tool) * Test runner (script mktests) * New luaotfload-tool option: ``--no-reload`` * ``luaotfload-tool --find`` now understands request syntax * text (Lua script) version of the font index is filtered through gzip by default, the ``--no-compress`` option of luaotfload-tool will prevent this * rename ``luaotfload-merged.lua`` (the fontloader package from Context) to ``luaotfload-fontloader.lua`` * Treat arguments of the ``letterspace`` option as percentages; add ``kernfactor`` option that behaves as before. * Remove imported version of typo-krn.lua. Xetex-style per-font letterspacing is now the canonical method. * Merge functionality from extralibs (fake Context layer) into luaotfload-letterspace.lua as it is only needed there anyways. 2013/07/10, luaotfload v2.3a * Detect LuaJIT interpreter (LuaJITTeX) * Self-test functionality for luaotfload-tool.lua (option ``--diagnose``) 2013/07/03, luaotfload v2.3: * New experimental lookups: ``kpse`` (kpathsea), ``my`` (callback) * Precedence of texmf over system fonts can be requested using the ``--prefer-texmf`` option of luaotfload-tool * Resolve file names to full paths at later stage * Rewrite the output of ``\fontname`` via ``patch_font`` callback * Allow blacklisting directories * Drop compatibility layer * Remove dependency on luaotfload-lib-dir (references to dir.glob() and dir.mkdirs()) * luaotfload-tool now displays extensive information about a font if given the argument --inspect 2013/05/20, luaotfload v2.2: * There is now a central, non-personal dev repo on github: https://github.com/lualatex/luaotfload * Synchronisation with ConTeXt from TeXLive 2013, inducing backward-incompatible changes in the font structure. A backward-compatibility layer has been added for the current versions of fontspec, unicode-math and microtype, but it should disapear in a future version. * Synchronisation with ConTeXt is now easier and can be done by just updating luaotfload-merged.lua (<= luatex-fonts-merged.lua from the LuaTeX-Plain format) * Improved and extended documentation * Font filenames are stored in the database (file: lookups more efficient) * Optional caching of name: lookups (uses separate cache file) * Rewriting and increased fidelity of XeTeX emulation * Renaming mkluatexfontdb into luaotfload-tool (the old behavior is kept if the script is symlinked or renamed mkluatexfontdb) * Added options to luaotfload-tool for simple database queries * Logging facilities have been rewritten and allow for more granularity * All files have been renamed, abandoning cryptic acronyms; also the new prefix is "luaotfload" (<= "otfl") * The Adobe Glyph List (font-age.lua) is now built via script (mkglyphlist) * Hans adapted the font loader to several of our requests (attribute allocation, custom merged package name etc.) * Auxiliary functions for package authors * Man page for luaotfload-tool * Unsupported v1.3 codebase is included in the luaotfload-*lua files. Crude, but effective way to support older Luatex binaries * implemented basic cache control/stats option for luaotfload-tool * Character list is generated from char-def.lua (mkcharacters) 2013/04/27, luaotfload v1.3: * blacklisting lingoes.ttf (segfaults) * unblacklisting ttc fonts (warning: may break LuaTeX < 0.65) * fixing font cache file name with non-ascii characters 2013/04/25, luaotfload v1.29: * Reverting the unified resolver, as the database was rebuilt too often which made the compilation longer.
