8 * Changes in the m17n library 1.4.0
10 ** If the environment variable "M17NDIR" is not set, the directory
11 "~/.m17n.d" is serched for database files.
13 ** New function mfont_list_family_names () returns a list of available
16 ** New functions mlanguage_list (), mlanguage_code (),
17 mlanguage_name_list (), and mlanguage_text () return various
18 language-related information.
20 ** New functions mscript_list () and mscript_language_list () return
21 various script-related information.
23 ** New function msymbol_put_func (), msymbol_get_func (),
24 mplist_put_func (), mplist_get_func (), mface_put_hook (), and
25 mface_get_hook () are available to avoid unsafe casting of function
26 pointer. New macro M17N_FUNC and new type M17NFunc are also
30 * Changes in the m17n library 1.3.0
32 ** The `configure' script accepts the argument "--without-gui" to
33 suppress building GUI libraries.
35 ** The environment variable MDEBUG_OUTPUT_FILE can specify a file to
36 output the debugging log messages.
38 ** The member `candidate_changed' of MInputContext carries more
39 information; i.e. the list itself is changed, only an index is
42 ** The member `callback_list' of MInputDriver can have callback
43 functions `input-get-surrounding-text' and
44 `input-delete-surrounding-text'.
46 ** The minput_filter () function accepts special events
47 `input-focus-move', `input-focus-in', and `input-focus-out'.
49 ** Three letter codes of ISO639-2 are also accepted as language
52 ** New functions minput_get_description (), minput_get_commands (),
53 minput_assign_command_keys (), minput_get_variables (), and
54 minput_set_variable(), minput_get_title_icon() are introduced for
55 handling input methods.
57 ** New fucntions mtext_insert () and and mtext_replace () for
60 ** New functions mtext_uppercase (), mtext_titlecase (),
61 mtext_lowercase () implement "3.13 Default Case Operations" of The
64 ** New function mtext_line_break () implements the line breaking
65 algorithm of The Unicode Standard 4.0 UAX#14. The algorithm can be
66 controlled by the variable mdraw_line_break_option.
68 ** New function msymbol_is_managing_key () checks if a symbol is a
71 ** New function mtext_data () exports various information about
74 ** Function mfont_get_prop () accept properties `fontfile',
75 `font-acsent', `font-descent', and `max-advance'.
77 ** New function mfont_check () checks if a specific font can be used
78 for a specific script and language.
80 ** New function mface_equal () checks if two faces are equal or not.
83 * Changes in the m17n library 1.2.0
85 ** Two new variables MTEXT_FORMAT_UTF_16 and MTEXT_FORMAT_UTF_32.
86 They are initialized to one of MTEXT_FORMAT_UTF_16LE,
87 MTEXT_FORMAT_UTF_16BE, MTEXT_FORMAT_UTF_LE, MTEXT_FORMAT_UTF_32BE
88 dependending on the systems's endianess.
90 ** In the argument PLIST of mframe (), the key Mfont can be used to
91 specify which font-backend to use. The value must be Mx or Mfreetype.
93 ** New function mfont_list () returns a list of matching fonts.
95 ** New function m17n_status () returns the current initialization
98 ** New function minput_reset () resets the current input context.
100 ** Names of sample programs have prefix "m17n-" instead of single "m".
101 This is to avoid confiliction of program names included in the other
105 * Changes in the m17n library 1.1.0
107 ** The "configure" script now detects Fontconfig, Xft2, and GD
110 If Fontconfig library is found, the library find local font files
111 (that are to be handled by the Freetype library) by fontconfig, and if
112 Xft2 library is also found, draw text by Xft.
114 ** Mdevice (new symbol) is recoginized as a key in the argument PLIST
117 The value must be Mx (new symbol), Mgd (new symbol), or Mnil. See the
118 documentation of mframe () for more detail.
120 ** MDrawControl has a new member `anti_alias'.
122 If MDrawControl->anti_alias is nonzero, try to draw anti-aliased text
123 if local fonts are used for that text via Freetype. If Xft2 library
124 can be used, the anti-alias processing is done by Xft2's drawing
125 routine. Otherwise, the m17n library itself does it by assumming that
126 the background color is `background' property of a face.
128 ** Modification of face is now automatically refelected to the next
131 So, for instance, an application can change the default face of a
132 frame after the frame is created. The sample program "medit" utilize
135 ** New function mfontset_lookup () reports contents of a fontset.
137 ** New function mplist_deseriaze () parses an M-Text and generates a
140 ** The functions mfont_name () and mfont_from_name () are now obsolete
141 (still kept for backward compatibility). Use mfont_parse_name () and
142 mfont_unparse_name () instead.
144 ** The sample program "mdump" generates PNG image file instead of PBM.
146 It now runs only when the m17n library is configured with the Freetype
147 library and the GD library.
