8 * Changes in the m17n library 1.3.0
10 ** The `configure' script accepts the argument "--without-gui" to
11 suppress building GUI libraries.
13 ** The environment variable MDEBUG_OUTPUT_FILE can specify a file to
14 output the debugging log messages.
16 ** The member `candidate_changed' of MInputContext carries more
17 information; i.e. the list itself is changed, only an index is
20 ** The member `callback_list' of MInputDriver can have callback
21 functions `input-get-surrounding-text' and
22 `input-delete-surrounding-text'.
24 ** The minput_filter () function accepts special events
25 `input-focus-move', `input-focus-in', and `input-focus-out'.
27 ** Three letter codes of ISO639-2 are also accepted as language
30 ** New functions minput_get_description (), minput_get_commands (),
31 minput_assign_command_keys (), minput_get_variables (), and
32 minput_set_variable() are introduced for handling input methods.
34 ** New fucntions mtext_insert () and and mtext_replace () for
37 ** New functions mtext_uppercase (), mtext_titlecase (),
38 mtext_lowercase () implement "3.13 Default Case Operations" of The
41 ** New function mtext_line_break () implements the line breaking
42 algorithm of The Unicode Standard 4.0 UAX#14. The algorithm can be
43 controlled by the variable mdraw_line_break_option.
45 ** New function msymbol_is_managing_key () checks if a symbol is a
48 ** New function mtext_data () exports various information about
51 ** Function mfont_get_prop () accept properties `fontfile',
52 `font-acsent', `font-descent', and `max-advance'.
54 ** New function mfont_check () checks if a specific font can be used
55 for a specific script and language.
57 ** New function mface_equal () checks if two faces are equal or not.
60 * Changes in the m17n library 1.2.0
62 ** Two new variables MTEXT_FORMAT_UTF_16 and MTEXT_FORMAT_UTF_32.
63 They are initialized to one of MTEXT_FORMAT_UTF_16LE,
64 MTEXT_FORMAT_UTF_16BE, MTEXT_FORMAT_UTF_LE, MTEXT_FORMAT_UTF_32BE
65 dependending on the systems's endianess.
67 ** In the argument PLIST of mframe (), the key Mfont can be used to
68 specify which font-backend to use. The value must be Mx or Mfreetype.
70 ** New function mfont_list () returns a list of matching fonts.
72 ** New function m17n_status () returns the current initialization
75 ** New function minput_reset () resets the current input context.
77 ** Names of sample programs have prefix "m17n-" instead of single "m".
78 This is to avoid confiliction of program names included in the other
82 * Changes in the m17n library 1.1.0
84 ** The "configure" script now detects Fontconfig, Xft2, and GD
87 If Fontconfig library is found, the library find local font files
88 (that are to be handled by the Freetype library) by fontconfig, and if
89 Xft2 library is also found, draw text by Xft.
91 ** Mdevice (new symbol) is recoginized as a key in the argument PLIST
94 The value must be Mx (new symbol), Mgd (new symbol), or Mnil. See the
95 documentation of mframe () for more detail.
97 ** MDrawControl has a new member `anti_alias'.
99 If MDrawControl->anti_alias is nonzero, try to draw anti-aliased text
100 if local fonts are used for that text via Freetype. If Xft2 library
101 can be used, the anti-alias processing is done by Xft2's drawing
102 routine. Otherwise, the m17n library itself does it by assumming that
103 the background color is `background' property of a face.
105 ** Modification of face is now automatically refelected to the next
108 So, for instance, an application can change the default face of a
109 frame after the frame is created. The sample program "medit" utilize
112 ** New function mfontset_lookup () reports contents of a fontset.
114 ** New function mplist_deseriaze () parses an M-Text and generates a
117 ** The functions mfont_name () and mfont_from_name () are now obsolete
118 (still kept for backward compatibility). Use mfont_parse_name () and
119 mfont_unparse_name () instead.
121 ** The sample program "mdump" generates PNG image file instead of PBM.
123 It now runs only when the m17n library is configured with the Freetype
124 library and the GD library.
