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