Thus, even if +XEmacs-specific widgets (such as the basic text window, the Lucid +menubar, and the recently added tab control) can be adapted to render +text via Xft, older widgets (such as buttons and labels) and ``modern'' +widgets derived from traditional widgets (the progress gauge) still +expect their font resources to be converted to server-side fonts. Then +text is rendered by calls to the core protocol via Xlib, rather than by +calls to the XRender protocol via Xft. + +It's even possible to imagine a situation where a widget is composed of +components which draw their own text (＠emph{predefined widgets}) as well +as new components which can draw using more modern methods. Handling +this will either require reworking the Emacs face mechanism to provide a +way to determine whether this widget can use that font, or ways to give +each of several different widgets, even different components of a given +widget, a different face property.

[AC21.5] gnuserv-related doc improvements 20 years

From an external perspective, configuration of the +library consists of generating a valid XML tree and feeding that to +FcConfigParse. The only other mechanism provided to applications for +changing the running configuration is to add fonts and directories to the +list of application-provided font files. + +The intent is to make font configurations relatively static, and shared by +as many applications as possible. It is hoped that this will lead to more +stable font selection when passing names from one application to another. +XML was chosen as a configuration file format because it provides a format +which is easy for external agents to edit while retaining the correct +structure and syntax. + +Font configuration is separate from font matching; applications needing to +do their own matching can access the available fonts from the library and +perform private matching. The intent is to permit applications to pick and +choose appropriate functionality from the library instead of forcing them to +choose between this library and a private configuration mechanism. The hope +is that this will ensure that configuration of fonts for all applications +can be centralized in one place. Centralizing font configuration will make +simplify and regularize font installation and customization. + +＠node Font Properties, Font Matching, Font Configuration, Overview +＠section Font Properties + +While font patterns may contain essentially any properties, there are some +well known properties with associated types. Fontconfig uses some of these +properties for font matching and font completion. Others are provided as a +convenience for the applications rendering mechanism. Some symbolic +constants are provided for common values or enumerated types. +＠xref{Constants}, for the list of standard properties and values. + + +＠node Font Matching, Font List Matching, Font Properties, Overview +＠section Font Matching + +Fontconfig performs matching by measuring the distance from a provided +pattern to all of the available fonts in the system. The closest matching +font is selected. This ensures that a font will always be returned, but +doesn't ensure that it is anything like the requested pattern. + +Font matching starts with an application constructed pattern. The desired +attributes of the resulting font are collected together in an FcPattern +object. Each property of the pattern can contain one or more values; these +are listed in priority order; matches earlier in the list are considered +"closer" than matches later in the list. + +The initial pattern is modified by applying the list of editing instructions +specific to patterns found in the configuration; each consists of a match +predicate and a set of editing operations. They are executed in the order +they appeared in the configuration. Each match causes the associated +sequence of editing operations to be applied. + +After the pattern has been edited, a sequence of default substitutions are +performed to canonicalize the set of available properties; this avoids the +need for the lower layers to constantly provide default values for various +font properties during rendering. + +The canonical font pattern is finally matched against all available fonts. +The distance from the pattern to the font is measured for each of several +properties: foundry, charset, family, lang, spacing, pixelsize, style, +slant, weight, antialias, rasterizer and outline. This list is in priority +order---results of comparing earlier elements of this list weigh more +heavily than later elements. + +There is one special case to this rule; family names are split into two +bindings; strong and weak. Strong family names are given greater precedence +in the match than lang elements while weak family names are given lower +precedence than lang elements. This permits the document language to drive +font selection when any document specified font is unavailable. + +The pattern representing that font is augmented to include any properties +found in the pattern but not found in the font itself; this permits the +application to pass rendering instructions or any other data through the +matching system. Finally, the list of editing instructions specific to +fonts found in the configuration are applied to the pattern. This modified +pattern is returned to the application. + +The return value contains sufficient information to locate and rasterize the +font, including the file name, pixel size and other rendering data. As +none of the information involved pertains to the FreeType library, +applications are free to use any rasterization engine or even to take +the identified font file and access it directly. + +The match/edit sequences in the configuration are performed in two passes +because there are essentially two different operations necessary -- the +first is to modify how fonts are selected; aliasing families and adding +suitable defaults. The second is to modify how the selected fonts are +rasterized. Those must apply to the selected font, not the original pattern +as false matches will often occur. + +＠node Font List Matching, Font Names, Font Matching, Overview +＠section Font List Matching + +While many applications want to locate a single font best matching their +search criteria, other applications need to build a set of fonts which can +be used to present any Unicode data. Fontconfig provides an API to generate +a list sorted by the nearness of each font to the pattern. Every font in +the system is considered, the best matching fonts are placed first. The +application then can select whether the remaining fonts are unconditionally +included in the list, or whether they are included only if they cover +portions of Unicode not covered by any of the preceeding fonts. + +The list resulting from this match is represented by references to the +original font patterns and so consumes very little memory. Using a list +entry involves creating a pattern which combines the information from the +font with the information from the original pattern and executing the font +substitutions. + +＠node Font Names, LANG Tags, Font List Matching, Overview +＠section Font Names + +Fontconfig provides a textual representation for patterns that the library +can both accept and generate. The representation is in three parts, first a +list of family names, second a list of point sizes and finally a list of +additional properties: + +＠example + <families>-<point sizes>:<name1>=<values1>:<name2>=<values2>... +＠end example + +Values in a list are separated with commas. A hyphen or comma in a family +name must be escaped with a backslash. The name needn't include either +families or point sizes; they can be elided. If the family name only is +given, the hyphen may be omitted. If there are no additional properties, +no trailing colon should be used. In addition, there are +symbolic constants that simultaneously indicate both a name and a value. +Here are some examples: + +＠example +Times-12 12 point Times Roman +Times-12:bold 12 point Times Bold +Courier:italic Courier Italic in the default size +Monospace:matrix=1 .1 0 1 The users preferred monospace font + with artificial obliquing +Mikachan\-PB-16 12 point Mikachan-PB +＠end example + +＠node LANG Tags, , Font Names, Overview +＠section LANG Tags + +Each font in the database contains a list of languages it supports. This is +computed by comparing the Unicode coverage of the font with the orthography +of each language. Languages are tagged using an RFC-3066 compatible naming +and occur in two parts -- the ISO639 language tag followed a hyphen and then +by the ISO 3166 country code. The hyphen and country code may be elided. + +Fontconfig has orthographies for several languages built into the library. +No provision has been made for adding new ones aside from rebuilding the +library. It currently supports 122 of the 139 languages named in ISO 639-1, +141 of the languages with two-letter codes from ISO 639-2 and another 30 +languages with only three-letter codes. + +＠node The fontconfig API, Configuration File Format, Overview, Top +＠chapter The fontconfig API + +＠example +#include <fontconfig/fontconfig.h> +#include <fontconfig/fcfreetype.h> +＠end example + +＠menu +* Constants:: +* Data Types:: +* Functions:: +＠end menu + +＠node Constants, Data Types, The fontconfig API, The fontconfig API + +While fontconfig is designed to be extensible, it provides a comprehensive +set of standard properties and values for fonts. + +The following table gives the list of standard font properties.

This buf is now fixed and should never occur. + +*** Fixed a bug concerning accessing root-drives in native window-XEmacs + Fixes an annoying behavior of the native windows-version of XEmacs: When a + path contains only a drive-letter and a : (e.g. C:) then + `expand-file-name' (and a lot of other file-operations) do not interpret + this path as root of that drive. So ECB adds temporary a trailing + `directory-sep-char' and calls file-operations like `expand-file-name' + with this new path because then `expand-file-name' treats this as root-dir + of that drive. For all (X)Emacs-version besides the native-windows-XEmacs + this fix is not needed and takes no effect. + +*** Better recognizing of remote CVS-root-repositories for the VC-support + +** Enhancement for the VC-support + +*** New option `ecb-vc-xemacs-exclude-remote-cvs-repository' + This excludes directories with a remote cvs-repository from VC-check. This + option takes only effect for XEmacs and is needed cause of the outdated + VC-package of XEmacs which offers no heuristic state-checking and also no + option `vc-cvs-stay-local'. So this option takes only effect if + `vc-cvs-stay-local' is not avaiable. In this case ECB treats directories + which are managed by CVS but have a remote repository as if the directory + would not being managed by CVS (so the files are not checked for their + VC-state). This is done to avoid blocking XEmacs cause of running full + cvs-commands (e.g. ``cvs status'') for a bunch of files over the net. + +*** Added beta-support for Clearcase + There is already an identify-backend-function `ecb-vc-dir-managed-by-CC' + and a check-state-function `ecb-vc-check-CC-state' and an advice for + `clearcase-sync-from-disk' which enable automatic state-update after + checkin/out. These code seems to work quite well but nevertheless there + are some problems so this Clearcase-support is not added per default to + `ecb-vc-supported-backends'. + + So if you want Clearcase-support you have to customize the option + `ecb-vc-supported-backends' and add these functions mentioned above (the + advice of `clearcase-sync-from-disk' takes only effect if the function + `ecb-vc-dir-managed-by-CC' can be found in `ecb-vc-supported-backends' and + ECB is active!). But use it at your own risk. Of course the best would be + if a lot of people would test this Clearcase-support and fix the + encountered problems ;-).

In fact, patches which +provide Xft support have been available for several years, but the +authors have been unwilling to deal with several important issues which +block integration. These are ＠emph{Mule}, and more generally, +＠emph{face} support; ＠emph{widget} support (including the toolbar and +menubar); and ＠emph{redisplay refactoring}. + +＠c Describe Alexey Gladkov and Yury Konovalov's work. + +However, in late 2003 Eric Knauel <knauel＠(a)informatik.uni-tuebingen.de> +and Matthias Neubauer <neubauer＠(a)informatik.uni-freiburg.de> put forward +a relatively complete patch which was robust to daily use in ISO 8859-1 +locales, and Stephen Turnbull began work on the integration issues. At +this point a (private) CVS branch is available for Stephen's patch +(branch point tag ＠samp{sjt-xft-bp}, branch tag ＠samp{sjt-xft}), and +one may be made available for the Knauel-Matthias patch soon. + +＠menu +* Better Rendering Support -- Issues:: +* Better Rendering Support -- Implementation:: +* Better Rendering Support -- Current Status:: +* Better Rendering Support -- Configuration with the Interim Patches:: +＠end menu + + +＠node Better Rendering Support -- Issues, Better Rendering Support -- Implementation, , Future Work -- Better Rendering Support +＠subsection Better Rendering Support -- Issues +＠cindex better rendering support, issues +＠cindex issues, better rendering support + +Of course it's ``unfair'' to demand that the implementers of a nice +feature like anti-aliasing support deal with accumulated cruft of the +last few years, but somebody must, sometime soon. Even core developers +are complaining about how slow XEmacs is in some applications, and there +is reason to believe that some of the problem is in redisplay. +Adding more ＠emph{ad hoc} features to redisplay will make the whole +module more complex and unintelligible. Even if it doesn't inherently +further detract from efficiency, it will surely make reform and +refactoring harder. + +Similar considerations apply to Mule support. If Xft support is not +carefully designed, or implemented with Mule support soon, it will +undoubtedly make later Mule implementation far more difficult than it +needs to be, and require redundant work be done (＠emph{e.g.}, on +＠samp{Options} menu support). + +Besides the design issue---and many users are requesting more +flexibility, primarily face support, from the widgets---with widget +support there is also an aesthetic issue. It is horribly unimpressive to +have clunky bitmapped fonts on the decorations when pleasant antialiased +fonts are available in the buffer. + +Finally, these issues interact. Widgets and faces are inherently +heavyweight objects, requiring orders of magnitude more computation than +simply displaying a string in a fixed font. This will have an +efficiency impact, of course. And they interact with each other; Mule +was designed for use in buffers and display in Emacs windows---but a +widget's content is usually not a buffer, and widgets need not be +displayed in a window, but may appear in other contexts, especially in +the gutters. So specifiers will probably have to be reworked, in order +to properly support display of different faces in non-buffer, non-window +contexts. + +＠node Better Rendering Support -- Implementation, Better Rendering Support -- Current Status, Better Rendering Support -- Issues, Future Work -- Better Rendering Support +＠subsection Better Rendering Support -- Implementation +＠cindex better rendering support, implementation +＠cindex implementation, better rendering support + +Stephen is thinking in terms of the following components of a +comprehensive proposal. + +＠table ＠strong +＠item Font configuration +In XEmacs, font configuration is handled via ＠emph{faces}. Currently +XEmacs uses a special type of ＠emph{font specifier} to map XEmacs +locales to font names. Especially under X11, this can cause annoying +problems because of the unreliability of X servers' mappings from +＠samp{XLFD} names to X11 fonts, over which XEmacs has no influence +whatsoever. However, the ＠file{fontconfig} library which is used with +＠file{Xft} provides much more reliable mapping, along with a more +reliably parsable naming scheme similar to that used by TrueType fonts +on MS Windows and the Macintosh. Since the capabilities of font +specifiers and ＠file{fontconfig} overlap, we should consider using +＠file{fontconfig} instead of ＠samp{XLFD} names. This implies that use +of ＠file{Xft}'s rendering functionality should be separated from use of +＠file{fontconfig}. + +＠item Font menus +The ＠samp{Options->Font} and ＠samp{Options->Font Sizes} menus are +broken, by design, not just by ＠file{Xft}. Although they work better +in Eric and Matthias's patch than in Stephen's, even their version has +the problem that many fonts are unavailable because they don't match the +current size---which is very strange, since ＠file{Xft} fonts are of +course scalable. But the whole idea of requiring that the font match +the size is strange. And the ＠samp{Options->Font Weights} menu is just +disabled, and has been for eons. + +＠item X resources +Currently in Stephen's patch there are ＠emph{four} treatments of font +resources. There are the ＠samp{XEmacs.(a)var{face}.attributeFont} +resources used to set a single global font specification. In the +widgets, some (still) have a ＠samp{font} resource using the automatic +＠file{Xt} resource conversion to ＠samp{FontStruct}, some have separate +＠samp{font} and ＠samp{xftFont} resources with the former automatically +converted to ＠samp{FontStruct} by ＠file{Xt} and the latter left as a +string, to be converted by ＠samp{XftParseName} later, and some have a +single ＠samp{font} resource which is converted to ＠samp{FontStruct} by +＠file{Xt} or the latter left as a string, depending on whether +＠file{Xft} was enabled by ＠samp{configure} or not. + +Stephen thinks that all of these should be converted to use the face +approach, perhaps with some way to set specifications for individual +widgets, frames, or buffers. This will require some careful design work +to incorporate face support in the widgets. We should just accept any +or all of ＠samp{font}, ＠samp{fontSet}, and ＠samp{fontList} resources, +treat them all as lists of font names, either ＠samp{XLFD}- or +＠file{fontconfig}-style, parse them ourselves (ie, not use the ＠file{Xt} +resource manager), and add them to font specifiers as appropriate. But +this will require a bit of thought to obey POLA vis-a-vis usual ＠file{Xt} +conventions. + +＠item Rendering engine objects +With the introduction of the ``Xft patch,'' the X11, Macintosh, and MS +Windows platforms are all able to support multiple font rendering +engines in the same binary. Generically, there are several tasks that +must be accomplished to render text on the display. In both cases the +code is rather disorganized, with substantial cross-platform duplication +of similar routines. While it may not be worthwhile to go the whole way +to ＠samp{RENDERER_HAS_METHOD} and ＠samp{MAYBE_RENDMETH}, refactoring +these modules around the notion of interfacing a ``generic rendering +engine interface'' to ``text'' seems like a plausible way to focus this +work. + +＠item Colors, fonts, and faces +Besides the rendering engine itself, the XEmacs implementations of these +objects are poorly supported by current widget implementations, +including the traditional menubar and toolbar, as well as the more +recent button, tab control, and progress bar widgets. The refactoring +suggested under ``Rendering engine objects'' should be conducted with an +eye to making these widgets support faces, perhaps even to the extent of +allowing rendering to X pixmaps (which some Athena widgets support, +although they will not support rendering via Xft directly). Especially +with ＠samp{XRender} technology this should not be horribly inefficient. + +＠item Specifiers, charsets, and languages +Traditionally Mule uses a rather rigid and low-level abstraction, the +＠emph{charset}, to characterize font repertoires. Unfortunately, +support for a given charset is generally neither necessary nor +sufficient to support a language. Worse, although X11's only means for +indicating font repertoires is the font's ＠emph{registry}, the actual +repertoire of many fonts is either deficient or font-dependent. The +only convenience is that the registry maps directly to a Mule charset in +most cases, and vice versa. + +To date, XEmacs Mule has supported identification of appropriate fonts +to support a language's repertoire of characters by identifying the +repertoire as a subset of a union of charsets. To each charset there is +a regular expression matching the registry portion of a font name. Then +instantiation of a font proceeds by identifying the specifier domain, +and then walking down the list of specifications, matching the regexp +against font names until a match is found. That font is requested from +the system, and if not found, the process continues similarly until a +font that can be loaded is found. + +This has several problems. First, there's no guarantee that the union +will be disjoint. This problem manifests both in the case of display of +Unicode representations of text in the ＠samp{POSIX} default locale, +where glyphs are typically drawn from several inappropriate fonts. A +similar problem often occurs, though for a different reason, in +multilingual messages composed using ＠file{Gnus}'s ＠samp{message-mode} +and MIME support. This problem ＠emph{cannot} be avoided with the +current design; it is quite possible that a font desired in one context +will be shadowed by a font intended to get higher priority in a +semantically different but syntactically similar (as far as Mule can +tell) context. (Of course, one could attach a different face as a text +property, but that requires programming support; it can't be done by +user configuration.) The problem is only exacerbated as more and more +Unicode fonts, supporting large repertoires with substantial overlap +across fonts, are designed and published. + +A second problem is that registry names are often inaccurate. For +example, the Japanese JIS X 0208 standard was first published in 1978 +(as a relabelling of an older standard). It was then revised in 1983, +again in 1990, and once again in 2000, with slight changes to the +repertoire and mapping in each revision. Technically, these standards +can be distinguished in properly named fonts as ＠samp{jisx0208.1978}, +(a)samp{jisx0208.1983}, ＠samp{jisx0208.1990}, ＠samp{jisx0208.2000}, but +all of them are commonly simply labelled ＠samp{jisx0208}, and Western +distributors, of course, generally lack the expertise to correctly +relabel them. + +A third problem is that you generally can't tell if there are ``holes'' +in the repertoire until you try to display the glyph. + +All of this tends to break standard idioms for handling Mule fonts in +＠file{init} files because they depend on charsets being disjoint +repertoires. + +The TrueType fonts (and the later OpenType standard) provides for a +proper character set query (as a Boolean vector indexed by Unicode code +points), as well as providing a list of supported languages. + +I propose that we take advantage of these latter facilities by allowing +a font to be specified either as a string (a font name), or as a list +whose head is the font name and whose tail is a list of languages and +Mule charsets (for backward compatibility) that user intends to use the +font to display. This will probably require a change to the specifier +code. + +As mentioned above, specifiers will probably also have to be enhanced to +recognize ＠samp{widget} locales and domains, instead of the current hack +where special ＠samp{widget} and ＠samp{gui-element} faces are created. + +＠item Customize + +Customize needs to deal with all this stuff!! +＠end table + + +＠node Better Rendering Support -- Current Status, Better Rendering Support -- Configuration with the Interim Patches, Better Rendering Support -- Implementation, Future Work -- Better Rendering Support +＠subsection Better Rendering Support -- Current Status +＠cindex better rendering support, current status +＠cindex current status, better rendering support + +Stephen has a branch containing his stuff in XEmacs CVS.

The menubar on the other hand uses Font for both, but +converts to FontStruct if Xft is not compiled in, and leaves it as a +string if Xft is compiled in. There is no equivalent facility for +XftFont yet, and creating one that handles both FontStruct and XftFont +depending on XEmacs's configuration and the font name seems error-prone +at best. Probably we will revert to a simple string representation for +this resource, and convert to a face in XEmacs rather than a font in +Xt/Xft. +＠example +XEmacs*Tabs.xftFont: Bitstream Vera Sans-18 +XEmacs*menubar.font: Bitstream Vera Sans-18 +XEmacs.modeline.attributeFont: Bitstream Charter-26 +XEmacs.default.attributeFont: Bitstream Vera Sans Mono-24 +＠end example +No, I don't understand why I need to use different point sizes to get +what looks like good balance to my eyes.

XEmacs was crashing because the Athena Label +widget tried to access a nonexistent font in its initialization +routine. The font didn't exist because although no core X11 font +corresponding to the spec existed, an Xft font was found. So the XEmacs +font instance existed but it did not specify an X11 core font, only the +Xft font. When this object was used to initialize the font for the +Label widget, None (0) was passed to XtSetArgs, then XtCreateWidget was +called, and the internal initialization routine attempted to access that +(nonexistent) font while computing an X11 graphics context (GC). + +A similar issue applies to colors, but there Xft colors keep the pixel +data internally, so (serendipitously) the X11 color (＠emph{i.e.}, pixel) +member does get updated. + ＠item Colors, fonts, and faces Besides the rendering engine itself, the XEmacs implementations of these objects are poorly supported by current widget implementations, -- Graduate School of Systems and Information Engineering University of Tsukuba http://turnbull.sk.tsukuba.ac.jp/ Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Economics of Information Communication and Computation Systems Experimental Economics, Microeconomic Theory, Game Theory
