8 * Changes in the m17n library 1.5.5
10 This release is just for bug fixing.
13 * Changes in the m17n library 1.5.4
15 ** New coding system names "Shift_JIS" and "windows-XXXX" are
19 * Changes in the m17n library 1.5.3
21 This release is just for bug fixing.
24 * Changes in the m17n library 1.5.2
26 This release is just for bug fixing.
29 * Changes in the m17n library 1.5.1
31 This release is just for bug fixing.
34 * Changes in the m17n library 1.5.0
36 ** New API layer FLT is created.
38 ** New environment variable MDEBUG_FLT is available to turn on
39 printing debug information for FLT, and these are now obsolete;
40 MDEBUG_FONT_FLT, MDEBUG_FONT_OTF.
42 ** New functions mchartable_min_char () returns the mininum character.
43 that is set some value in a char-table. New funcion
44 mchartable_min_char () is for the maximum character.
47 * Changes in the m17n library 1.4.0
49 ** If the environment variable "M17NDIR" is not set, the directory
50 "~/.m17n.d" is serched for database files.
52 ** New function mfont_list_family_names () returns a list of available
55 ** New functions mlanguage_list (), mlanguage_code (),
56 mlanguage_name_list (), and mlanguage_text () return various
57 language-related information.
59 ** New functions mscript_list () and mscript_language_list () return
60 various script-related information.
62 ** New function msymbol_put_func (), msymbol_get_func (),
63 mplist_put_func (), mplist_get_func (), mface_put_hook (), and
64 mface_get_hook () are available to avoid unsafe casting of function
65 pointer. New macro M17N_FUNC and new type M17NFunc are also
69 * Changes in the m17n library 1.3.0
71 ** The `configure' script accepts the argument "--without-gui" to
72 suppress building GUI libraries.
74 ** The environment variable MDEBUG_OUTPUT_FILE can specify a file to
75 output the debugging log messages.
77 ** The member `candidate_changed' of MInputContext carries more
78 information; i.e. the list itself is changed, only an index is
81 ** The member `callback_list' of MInputDriver can have callback
82 functions `input-get-surrounding-text' and
83 `input-delete-surrounding-text'.
85 ** The minput_filter () function accepts special events
86 `input-focus-move', `input-focus-in', and `input-focus-out'.
88 ** Three letter codes of ISO639-2 are also accepted as language
91 ** New functions minput_get_description (), minput_get_commands (),
92 minput_assign_command_keys (), minput_get_variables (), and
93 minput_set_variable(), minput_get_title_icon() are introduced for
94 handling input methods.
96 ** New fucntions mtext_insert () and and mtext_replace () for
99 ** New functions mtext_uppercase (), mtext_titlecase (),
100 mtext_lowercase () implement "3.13 Default Case Operations" of The
101 Unicode Standard 4.0.
103 ** New function mtext_line_break () implements the line breaking
104 algorithm of The Unicode Standard 4.0 UAX#14. The algorithm can be
105 controlled by the variable mdraw_line_break_option.
107 ** New function msymbol_is_managing_key () checks if a symbol is a
110 ** New function mtext_data () exports various information about
113 ** Function mfont_get_prop () accept properties `fontfile',
114 `font-acsent', `font-descent', and `max-advance'.
116 ** New function mfont_check () checks if a specific font can be used
117 for a specific script and language.
119 ** New function mface_equal () checks if two faces are equal or not.
122 * Changes in the m17n library 1.2.0
124 ** Two new variables MTEXT_FORMAT_UTF_16 and MTEXT_FORMAT_UTF_32.
125 They are initialized to one of MTEXT_FORMAT_UTF_16LE,
126 MTEXT_FORMAT_UTF_16BE, MTEXT_FORMAT_UTF_LE, MTEXT_FORMAT_UTF_32BE
127 dependending on the systems's endianess.
129 ** In the argument PLIST of mframe (), the key Mfont can be used to
130 specify which font-backend to use. The value must be Mx or Mfreetype.
132 ** New function mfont_list () returns a list of matching fonts.
134 ** New function m17n_status () returns the current initialization
137 ** New function minput_reset () resets the current input context.
139 ** Names of sample programs have prefix "m17n-" instead of single "m".
140 This is to avoid confiliction of program names included in the other
144 * Changes in the m17n library 1.1.0
146 ** The "configure" script now detects Fontconfig, Xft2, and GD
149 If Fontconfig library is found, the library find local font files
150 (that are to be handled by the Freetype library) by fontconfig, and if
151 Xft2 library is also found, draw text by Xft.
153 ** Mdevice (new symbol) is recoginized as a key in the argument PLIST
156 The value must be Mx (new symbol), Mgd (new symbol), or Mnil. See the
157 documentation of mframe () for more detail.
159 ** MDrawControl has a new member `anti_alias'.
161 If MDrawControl->anti_alias is nonzero, try to draw anti-aliased text
162 if local fonts are used for that text via Freetype. If Xft2 library
163 can be used, the anti-alias processing is done by Xft2's drawing
164 routine. Otherwise, the m17n library itself does it by assumming that
165 the background color is `background' property of a face.
167 ** Modification of face is now automatically refelected to the next
170 So, for instance, an application can change the default face of a
171 frame after the frame is created. The sample program "medit" utilize
174 ** New function mfontset_lookup () reports contents of a fontset.
176 ** New function mplist_deseriaze () parses an M-Text and generates a
179 ** The functions mfont_name () and mfont_from_name () are now obsolete
180 (still kept for backward compatibility). Use mfont_parse_name () and
181 mfont_unparse_name () instead.
183 ** The sample program "mdump" generates PNG image file instead of PBM.
185 It now runs only when the m17n library is configured with the Freetype
186 library and the GD library.
