Device and frame internals are referred to from +many places in the redisplay and console code. The best that can be +done therefore is to create a whole new console type, even though much +code will be shared. (Ben Wing has complained about the code +duplication in the GTK+ v1 console, and probably would not be happy with +the unpublished Qt console or Andrew Choi's Carbon console, but it's +hard to see how those consoles could have been done better without +fixing the abstractions in the X (actually Xt), MS Windows, and tty +consoles as well as doing a complete refactoring of the console, device, +and frame code.) + +What is desireable is sharing console, device, and frame methods across +platforms in a more general way, reducing the amount of duplicated code +by pulling it back into the redisplay engine proper or the Lisp modules +as appropriate. For example, we should be able to use +＠samp{make-frame-on-device} to share a single X connection among GTK, X, +and Xft frames. Xft is partially implemented, but GTK would be much +harder (impossible?) because it has its own event loop. (Xft shares the +Xt event loop with the X console.) + +The way all methods get added to the console type is uncool. A console +should be a composite, which indicates a collection of I/O resources +``used together.'' It should indicate where operations that change +``focus'' search for targets, ＠emph{i.e.}, by default new frames are +created on the selected device of the console where the input that +invoked the command was received, ＠samp{pop-to-buffer-other-window} only +considers existing windows on the same device of the same console, +(a)emph{etc.} But it should be possible to assemble consoles out of +component input channels, imaging devices, and multimedia (audio) +channels. + +The following notes may provide some guidance to those who wish to +create new console types (＠emph{i.e.}, port the redisplay code to a new +platform). They are based on an unsuccessful attempt to refactor the +Xft code into a new console type while sharing most routines with the X +console. (For clarification or suggestions, feel free to write +＠email{stephen＠(a)xemacs.org,Stephen Turnbull}.) + +The first thing to realize is that the naming of many modules obscures +their relationship to the console abstraction. For example, the +＠file{objects-＠var{console-type}}, ＠file{redisplay-＠var{console-type}}, +and ＠file{glyphs-＠var{console-type}} series of modules have nothing to +do with Lisp objects and little to do with redisplay, respectively. +Rather they implement abstractions used for rendering on each console +type, such as fonts and colors (＠file{objects}) and string and graphics +drawing primitives (＠file{rendering}). These modules are conceptually +part of the console implementations, not part of redisplay or Lisp. + +Public methods of a console are implemented as C functions declared +＠code{static}, following a rigid naming convention: +＠samp{＠var{console-type}_＠var{method-name}}. Methods are bound to the +console type in the ＠samp{console_type_create_＠var{file}} functions for +each console component (console, device, and frame) using the +＠samp{CONSOLE_HAS_METHOD} family of macros. Methods for displaying +images are bound using the ＠samp{IIFORMAT_HAS_DEVMETHOD} family of +macros. Methods are invoked using the ＠samp{CONMETH}, ＠samp{DEVMETH}, +and ＠samp{FRAMEMETH} families of macros, which look up the relevant +methods in the object's table of methods. + +(a)strong{N.B.} All of the object tables are actually references to +console method tables. To create a variant of an existing console, +there is a ＠samp{CONSOLE_INHERITS_METHOD} constructor, but this actually +constructs the name of the parent's method pointer and stores in the +derived console type's method table. Of course this is time-efficient, +and since there are few console types it is a neglible waste of space. +However in practice this may have contributed to breaking the various +abstractions, and the variant console must be coded in the same file as +the parent (because the methods are static). Another minor symptom of +the incompleteness of the abstraction is the fact that the API for +inheritance of device methods for image formats is named +＠samp{IIFORMAT_HAS_SHARED_METHOD}, although the semantics are identical. + +One problem encountered in attempting to create an Xft console type as a +derivative of the X console type was that there is no support for such +union types in the consistency-checking code, whether for the +fundamental Lisp consistency checks (the ＠samp{CHECK_SOMETHING} family +of macros) or for the error-checking variants of many functions. These +APIs all simply check for the apparent console type, which is a single +symbol (or enumerator). + +To create a new console with mostly new methods, it's probably best to +copy all of the ＠file{＠var{function}-＠var{console-type}} files from a +similar console (or several, if the new console type seems like a +combination of several existing console types), renaming the files by +substituting ＠var{new-console-type} for ＠var{console-type}. Then +proceed in the obvious way by renaming methods from +＠samp{＠var{console-type}_＠var{method-name}} to +＠samp{＠var{new-console-type}_＠var{method-name}}, and implementing them. + +Once you've done that, then the fun starts. Insert the initialization +functions (＠samp{syms_of_＠var{file}}, ＠samp{vars_of_＠var{file}}, +＠samp{console_type_create_＠var{file}}, ＠emph{etc.}) in ＠samp{main_1} in +(a)file{emacs.c}. + +Add a device creation function ＠samp{make-＠var{console-type}-device} in +(a)file{device.el}. Add the device type to the calls to +＠samp{Face-frob-property} in ＠file{faces.el}, as well as calls to the +device initializer functions for devices and frames, and ``additional +frobbing'' in that file. + +You may wish to add an option to force the initial frame to that device +type to ＠file{emacs.c}. Don't forget to document it in the command help +function in ＠file{startup.el}. + +You may need to add support for your console type in +＠samp{init_event_stream} in ＠file{event-stream.c}. + +If your console has a different UI for fonts or colors, or adds new +capability, you may need to add a ＠file{(a)var{console-type}-faces.el} +file, or add code to the ＠file{(a)var{parent-type}-faces.el} file, to +support new font or color capability. Probably initialization code in +(a)file{faces.c} will be needed too. + +A check for the console type is probably needed in ＠samp{init_redisplay} +in ＠file{redisplay.c}. + +Ditto for the ＠file{(a)var{console-type}-init.el} file. + +Don't forget that Emacs windows are console-dependent, too. At least a +＠samp{WINDOW_＠var{console-type}_P}-checking macro should be added in +(a)file{window-impl.h}. -＠node Modules for the Basic Displayable Lisp Objects, , The Window Object, Consoles; Devices; Frames; Windows +Note that this project failed; there are probably many other details to +be implemented that I didn't get to.

The Lisp types returned will conform to TYPE: string string boolean `t' or `nil' integer integer double (float) float matrix not implemented charset not implemented void not implemented Symbols with names of the form "fc-result-DESCRIPTION" are returned when the desired value is not available. These are fc-result-type-mismatch the value found has an unexpected type fc-result-no-match there is no such attribute fc-result-no-id there is no value for the requested ID The types of the following standard properties are predefined by fontconfig. The symbol 'fc-result-type-mismatch will be returned if the object exists but TYPE does not match the predefined type. It is best not to specify a type for predefined properties, as a mistake here ensures error returns on the correct type. Each standard property has a convenience accessor defined in fontconfig.el, named in the form "fc-pattern-get-PROPERTY". The convenience functions are preferred to `fc-pattern-get' since a typo in the string naming a property will result in a silent null return, while a typo in a function name will usually result in a compiler or runtime \"not fboundp\" error. You may use `defsubst' to define convenience functions for non-standard properties. family String Font family name style String Font style. Overrides weight and slant slant Int Italic, oblique or roman weight Int Light, medium, demibold, bold or black size Double Point size aspect Double Stretches glyphs horizontally before hinting pixelsize Double Pixel size spacing Int Proportional, monospace or charcell foundry String Font foundry name antialias Bool Whether glyphs can be antialiased hinting Bool Whether the rasterizer should use hinting verticallayout Bool Use vertical layout autohint Bool Use autohinter instead of normal hinter globaladvance Bool Use font global advance data file String The filename holding the font index Int The index of the font within the file ftface FT_Face Use the specified FreeType face object rasterizer String Which rasterizer is in use outline Bool Whether the glyphs are outlines scalable Bool Whether glyphs can be scaled scale Double Scale factor for point->pixel conversions dpi Double Target dots per inch rgba Int unknown, rgb, bgr, vrgb, vbgr, none - subpixel geometry minspace Bool Eliminate leading from line spacing charset CharSet Unicode chars encoded by the font lang String List of RFC-3066-style languages this font supports The FT_Face, Matrix, CharSet types are unimplemented, so the corresponding properties are not accessible from Lisp at this time. If the value of a property returned has type FT_Face, FcCharSet, or FcMatrix, `fc-result-type-mismatch' is returned. The following properties which were standard in Xft v.1 are obsolete in Xft v.2: encoding, charwidth, charheight, core, and render. */ (pattern, property, id, type)) { FcChar8 *fc_property; /* UExtbyte * */ FcResult fc_result; FcValue fc_value; /* process arguments */ CHECK_FCPATTERN (pattern); #if 0 /* Don't support the losing symbol-for-property interface. */ property = SYMBOLP (property) ? symbol_name (XSYMBOL (property)) : property; #endif if (STRINGP (property)) { fc_property = (FcChar8 *) extract_fcapi_string (property); } else { /* if we allow symbols, this would need to be list3 (Qlambda, list1 (Qobject), list3 (Qor, list2 (Qstringp, Qobject), list2 (Qsymbolp, Qobject))) or something like that? */ dead_wrong_type_argument (Qstringp, property); } if (!NILP (id)) CHECK_NATNUM (id); if (!NILP (type)) CHECK_SYMBOL (type); /* get property */ fc_result = FcPatternGet (XFCPATTERN_PTR (pattern), fc_property, NILP (id) ? 0 : XINT(id), &fc_value); switch (fc_result) { case FcResultMatch: /* wrap it and return */ switch (fc_value.type) { case FcTypeInteger: return ((!NILP (type) && !EQ (type, Qinteger)) ?
