8 * Changes in the m17n library 1.6.0
10 ** Libtool 1.5.26 can be used to build the library from CVS source.
13 * Changes in the m17n library 1.6.0
15 ** For handling new spec in the Unicode 5.2, these new APIs are added
17 mflt_enable_new_feature
18 mflt_iterate_otf_feature
23 * Changes in the m17n library 1.5.5
25 ** Now libtool 2.2.4 or the later is required to build the library
29 * Changes in the m17n library 1.5.4
31 ** New coding system names "Shift_JIS" and "windows-XXXX" are
35 * Changes in the m17n library 1.5.3
37 This release is just for bug fixing.
40 * Changes in the m17n library 1.5.2
42 This release is just for bug fixing.
45 * Changes in the m17n library 1.5.1
47 This release is just for bug fixing.
50 * Changes in the m17n library 1.5.0
52 ** New API layer FLT is created.
54 ** New environment variable MDEBUG_FLT is available to turn on
55 printing debug information for FLT, and these are now obsolete;
56 MDEBUG_FONT_FLT, MDEBUG_FONT_OTF.
58 ** New functions mchartable_min_char () returns the mininum character.
59 that is set some value in a char-table. New funcion
60 mchartable_min_char () is for the maximum character.
63 * Changes in the m17n library 1.4.0
65 ** If the environment variable "M17NDIR" is not set, the directory
66 "~/.m17n.d" is serched for database files.
68 ** New function mfont_list_family_names () returns a list of available
71 ** New functions mlanguage_list (), mlanguage_code (),
72 mlanguage_name_list (), and mlanguage_text () return various
73 language-related information.
75 ** New functions mscript_list () and mscript_language_list () return
76 various script-related information.
78 ** New function msymbol_put_func (), msymbol_get_func (),
79 mplist_put_func (), mplist_get_func (), mface_put_hook (), and
80 mface_get_hook () are available to avoid unsafe casting of function
81 pointer. New macro M17N_FUNC and new type M17NFunc are also
85 * Changes in the m17n library 1.3.0
87 ** The `configure' script accepts the argument "--without-gui" to
88 suppress building GUI libraries.
90 ** The environment variable MDEBUG_OUTPUT_FILE can specify a file to
91 output the debugging log messages.
93 ** The member `candidate_changed' of MInputContext carries more
94 information; i.e. the list itself is changed, only an index is
97 ** The member `callback_list' of MInputDriver can have callback
98 functions `input-get-surrounding-text' and
99 `input-delete-surrounding-text'.
101 ** The minput_filter () function accepts special events
102 `input-focus-move', `input-focus-in', and `input-focus-out'.
104 ** Three letter codes of ISO639-2 are also accepted as language
107 ** New functions minput_get_description (), minput_get_commands (),
108 minput_assign_command_keys (), minput_get_variables (), and
109 minput_set_variable(), minput_get_title_icon() are introduced for
110 handling input methods.
112 ** New fucntions mtext_insert () and and mtext_replace () for
115 ** New functions mtext_uppercase (), mtext_titlecase (),
116 mtext_lowercase () implement "3.13 Default Case Operations" of The
117 Unicode Standard 4.0.
119 ** New function mtext_line_break () implements the line breaking
120 algorithm of The Unicode Standard 4.0 UAX#14. The algorithm can be
121 controlled by the variable mdraw_line_break_option.
123 ** New function msymbol_is_managing_key () checks if a symbol is a
126 ** New function mtext_data () exports various information about
129 ** Function mfont_get_prop () accept properties `fontfile',
130 `font-acsent', `font-descent', and `max-advance'.
132 ** New function mfont_check () checks if a specific font can be used
133 for a specific script and language.
135 ** New function mface_equal () checks if two faces are equal or not.
138 * Changes in the m17n library 1.2.0
140 ** Two new variables MTEXT_FORMAT_UTF_16 and MTEXT_FORMAT_UTF_32.
141 They are initialized to one of MTEXT_FORMAT_UTF_16LE,
142 MTEXT_FORMAT_UTF_16BE, MTEXT_FORMAT_UTF_LE, MTEXT_FORMAT_UTF_32BE
143 dependending on the systems's endianess.
145 ** In the argument PLIST of mframe (), the key Mfont can be used to
146 specify which font-backend to use. The value must be Mx or Mfreetype.
148 ** New function mfont_list () returns a list of matching fonts.
150 ** New function m17n_status () returns the current initialization
153 ** New function minput_reset () resets the current input context.
155 ** Names of sample programs have prefix "m17n-" instead of single "m".
156 This is to avoid confiliction of program names included in the other
160 * Changes in the m17n library 1.1.0
162 ** The "configure" script now detects Fontconfig, Xft2, and GD
165 If Fontconfig library is found, the library find local font files
166 (that are to be handled by the Freetype library) by fontconfig, and if
167 Xft2 library is also found, draw text by Xft.
169 ** Mdevice (new symbol) is recoginized as a key in the argument PLIST
172 The value must be Mx (new symbol), Mgd (new symbol), or Mnil. See the
173 documentation of mframe () for more detail.
175 ** MDrawControl has a new member `anti_alias'.
177 If MDrawControl->anti_alias is nonzero, try to draw anti-aliased text
178 if local fonts are used for that text via Freetype. If Xft2 library
179 can be used, the anti-alias processing is done by Xft2's drawing
180 routine. Otherwise, the m17n library itself does it by assumming that
181 the background color is `background' property of a face.
183 ** Modification of face is now automatically refelected to the next
186 So, for instance, an application can change the default face of a
187 frame after the frame is created. The sample program "medit" utilize
190 ** New function mfontset_lookup () reports contents of a fontset.
192 ** New function mplist_deseriaze () parses an M-Text and generates a
195 ** The functions mfont_name () and mfont_from_name () are now obsolete
196 (still kept for backward compatibility). Use mfont_parse_name () and
197 mfont_unparse_name () instead.
199 ** The sample program "mdump" generates PNG image file instead of PBM.
201 It now runs only when the m17n library is configured with the Freetype
202 library and the GD library.
