* Handle FC_CHARCELL in xftfont_openLars Ingebrigtsen2019-11-17
| | | | | | * src/xftfont.c (xftfont_open): FC_CHARCELL is apparently an alias for FC_DUAL used in some east Asian fonts (bug#35079). Modelled after a patch suggested by Kenichi Handa.

* Prefer HTTPS to FTP and HTTP in documentationPaul Eggert2017-09-13
| | | | | | | | | | | | | Most of this change is to boilerplate commentary such as license URLs. This change was prompted by ftp://ftp.gnu.org's going-away party, planned for November. Change these FTP URLs to https://ftp.gnu.org instead. Make similar changes for URLs to other organizations moving away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and fsf.org when this works, as this will further help defend against man-in-the-middle attacks (for this part I omitted the MS-DOS and MS-Windows sources and the test tarballs to keep the workload down). HTTPS is not fully working to lists.gnu.org so I left those URLs alone for now.

* Reduce color allocation/query traffic in the TrueColor case.Ken Raeburn2015-10-08
| | | | | | | | | | | | | | | | | | | | | | | | When working with an X visual with TrueColor class, pixel values can be generated from the RGB values according to mask value provided by the server on connection. Some of the image-handling code was already doing this. * src/xterm.h (x_make_truecolor_pixel): New function; code taken from lookup_rgb_color. (x_mutable_colormap): New function. * src/image.c (lookup_rgb_color): Move pixel composition code to x_make_truecolor_pixel. (x_kill_gs_process): Call x_mutable_colormap. * src/xfaces.c (x_free_colors, x_free_dpy_colors): Call x_mutable_colormap. * src/xftfont.c (xftfont_get_colors): Call x_query_colors. * src/xterm.c (x_query_colors): For a TrueColor display, decompose the pixel value into RGB values directly, and don't send a request to the server. (x_alloc_nearest_color): For a TrueColor display, construct the pixel value with x_make_truecolor_pixel. (x_copy_color): For an immutable color map, just return the provided pixel value.
* Fix display of glyphless characters with problematic fontsEli Zaretskii2015-05-28
| | | | | | | | | | | | | | | | | | | | | | | | * src/w32term.c (x_draw_glyph_string_background): Force redraw of glyph string background also when the font in use claims preposterously large global height value. Helps to remove artifacts left from previous displays when glyphless characters are displayed as hex code in a box. * src/xterm.c (x_draw_glyph_string_background): Force redraw of glyph string background also when the font in use claims preposterously large global height value. Helps to remove artifacts left from previous displays when glyphless characters are displayed as hex code in a box. * src/w32font.c (w32font_draw): Fix background drawing for glyphless characters that display as acronyms or hex codes in a box. * src/xftfont.c (xftfont_draw): Fix background drawing for glyphless characters that display as acronyms or hex codes in a box. * src/xdisp.c (produce_glyphless_glyph): Compute reasonable values for it->ascent and it->descent when the font claims preposterously large global values. (FONT_TOO_HIGH): Move from here... * src/dispextern.h (FONT_TOO_HIGH): ...to here.
* Use bool for boolean in xfont.c, xftfont.c, xgselect.cPaul Eggert2015-01-21
| | | | | | | | | | * xfont.c (xfont_driver, xfont_chars_supported) (xfont_text_extents): * xftfont.c (xftfont_get_colors, xftfont_open) (xftfont_prepare_face, xftfont_done_face) (xftfont_cached_font_ok): * xgselect.c (xg_select): Use bool for boolean.
* Prefer INLINE functions in font.h to match style used in lisp.hDmitry Antipov2015-01-16
| | | | | | | | | | | | * font.h (FONTP, FONT_SPEC_P, FONT_ENTITY_P, FONT_OBJECT_P) (CHECK_FONT, CHECK_FONT_SPEC, CHECK_FONT_ENTITY, CHECK_FONT_OBJECT) (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT, CHECK_FONT_GET_OBJECT): Now functions. * font.c (Ffont_otf_alternates, Fquery_font, Ffont_get_glyphs): * ftfont.c (ftfont_shape): * macfont.m (macfont_shape): * w32uniscribe.c (uniscribe_shape): * xftfont.c (xftfont_shape): Adjust CHECK_FONT_GET_OBJECT users.
* Compute C decls for DEFSYMs automaticallyPaul Eggert2015-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes Bug#15880. This patch also makes Q constants (e.g., Qnil) constant addresses from the C point of view. * make-docfile.c: Revamp to generate table of symbols, too. Include <stdbool.h>. (xstrdup): New function. (main): Don't process the same file twice. (SYMBOL): New constant in enum global_type. (struct symbol): Turn 'value' member into a union, either v.value for int or v.svalue for string. All uses changed. (add_global): New arg svalue, which overrides value, so that globals can have a string value. (close_emacs_global): New arg num_symbols; all uses changed. Output lispsym decl. (write_globals): Output symbol globals too. Output more ATTRIBUTE_CONST, now that Qnil etc. are C constants. Output defsym_name table. (scan_c_file): Move most of guts into ... (scan_c_stream): ... new function. Scan for DEFSYMs and record symbols found. Don't read past EOF if file doesn't end in newline. * alloc.c, bidi.c, buffer.c, bytecode.c, callint.c, casefiddle: * casetab.c, category.c, ccl.c, charset.c, chartab.c, cmds.c, coding.c: * composite.c, data.c, dbusbind.c, decompress.c, dired.c, dispnew.c: * doc.c, editfns.c, emacs.c, eval.c, fileio.c, fns.c, font.c, fontset.c: * frame.c, fringe.c, ftfont.c, ftxfont.c, gfilenotify.c, gnutls.c: * image.c, inotify.c, insdel.c, keyboard.c, keymap.c, lread.c: * macfont.m, macros.c, minibuf.c, nsfns.m, nsfont.m, nsimage.m: * nsmenu.m, nsselect.m, nsterm.m, print.c, process.c, profiler.c: * search.c, sound.c, syntax.c, term.c, terminal.c, textprop.c, undo.c: * window.c, xdisp.c, xfaces.c, xfns.c, xftfont.c, xmenu.c, xml.c: * xselect.c, xsettings.c, xterm.c: Remove Q vars that represent symbols (e.g., Qnil, Qt, Qemacs). These names are now defined automatically by make-docfile. * alloc.c (init_symbol): New function. (Fmake_symbol): Use it. (c_symbol_p): New function. (valid_lisp_object_p, purecopy): Use it. * alloc.c (marked_pinned_symbols): Use make_lisp_symbol instead of make_lisp_ptr. (garbage_collect_1): Mark lispsym symbols. (CHECK_ALLOCATED_AND_LIVE_SYMBOL): New macro. (mark_object): Use it. (sweep_symbols): Sweep lispsym symbols. (symbol_uses_obj): New function. (which_symbols): Use it. Work for lispsym symbols, too. (init_alloc_once): Initialize Vpurify_flag here; no need to wait, since Qt's address is already known now. (syms_of_alloc): Add lispsym count to symbols_consed. * buffer.c (init_buffer_once): Compare to Qnil, not to make_number (0), when testing whether storage is all bits zero. * dispextern (struct image_type): * font.c (font_property_table): * frame.c (struct frame_parm_table, frame_parms): * keyboard.c (scroll_bar_parts, struct event_head): * xdisp.c (struct props): Use XSYMBOL_INIT (Qfoo) and struct Lisp_Symbol * rather than &Qfoo and Lisp_Object *, since Qfoo is no longer an object whose address can be taken. All uses changed. * eval.c (run_hook): New function. Most uses of Frun_hooks changed to use it, so that they no longer need to take the address of a Lisp sym. (syms_of_eval): Don't use DEFSYM on Vrun_hooks, as it's a variable. * frame.c (syms_of_frame): Add defsyms for the frame_parms table. * keyboard.c (syms_of_keyboard): Don't DEFSYM Qmenu_bar here. DEFSYM Qdeactivate_mark before the corresponding var. * keymap.c (syms_of_keymap): Use DEFSYM for Qmenu_bar and Qmode_line instead of interning their symbols; this avoids duplicates. (LISP_INITIALLY, TAG_PTR) (DEFINE_LISP_SYMBOL_BEGIN, DEFINE_LISP_SYMBOL_END, XSYMBOL_INIT): New macros. (LISP_INITIALLY_ZERO): Use it. (enum symbol_interned, enum symbol_redirect, struct Lisp_Symbol) (EXFUN, DEFUN_ARGS_MANY, DEFUN_ARGS_UNEVALLED, DEFUN_ARGS_*): Move decls up, to avoid forward uses. Include globals.h earlier, too. (make_lisp_symbol): New function. (XSETSYMBOL): Use it. (DEFSYM): Now just a placeholder for make-docfile. * lread.c (DEFINE_SYMBOLS): Define, for globals.h. (intern_sym): New function, with body taken from old intern_driver. (intern_driver): Use it. Last arg is now Lisp integer, not ptrdiff_t. All uses changed. (define_symbol): New function. (init_obarray): Define the C symbols taken from lispsym. Use plain DEFSYM for Qt and Qnil. * syntax.c (init_syntax_once): No need to worry about Qchar_table_extra_slots.
