|
124 coding-system VALUE is a list of coding systems that are good
|
|
|
125 for saving text written in this language environment.
|
|
|
126 This list serves as suggestions to the user;
|
|
|
127 in effect, as a kind of documentation.
|
|
|
128
|
|
|
129 coding-priority VALUE is a list of coding systems for this language
|
|
|
130 environment, in order of decreasing priority.
|
|
|
131 This is used to set up the coding system priority
|
|
|
132 list when you switch to this language environment.
|
|
|
133
|
|
|
134 input-method VALUE is a default input method for this language
|
|

135 environment.
|

136

|
|
137 features VALUE is a list of features requested in this

138 language environment.
|
|
|
139
|
|
|
140 tutorial VALUE is a tutorial file name written in the language.
|
|
|
141
|
|
|
142 locale VALUE is a list of locale expressions, which serve
|
|
|
143 two purposes: (1) Determining the language
|
|
|
144 environment from the current system locale at
|
|
|
145 startup, and (2) determining how to set the system
|
|
|
146 locale when the language environment is changed.
|
|
|
147 Each expression will be tried in turn, and should
|
|
|
148 be a string (for case (1), the string is matched
|
|
|
149 against the current locale using the regular
|
|
|
150 expression \"^STRING[^A-Za-z0-9]\"; for case (2),
|
|
|
151 the string is passed directly to
|
|
|
152 `set-current-locale' until a non-nil result is
|
|
|
153 returned), or a function of one argument. For
|
|
|
154 case (1), this argument will be a locale, and the
|
|
|
155 function should return t or nil to indicate
|
|
|
156 whether this locale matches the language
|
|
|
157 environment; for case (2), the argument will be
|
|
|
158 nil, and the function should call
|
|
|
159 `set-current-locale' itself and return the set
|
|
|
160 locale string if the locale was successfully set,
|
|
|
161 and nil otherwise.
|
|
428
|
162
|
|
771
|
163 NOTE: This property is *NOT* used under MS Windows;
|
|
|
164 instead, the `mswindows-locale' property is used.
|
|
|
165
|
|
|
166 cygwin-locale VALUE specifies a general Unix-style C library
|
|
|
167 locale that will be used to initialize the LANG
|
|
|
168 environment variable under MS Windows native, when the
|
|
|
169 system cannot test out the locales specified in the
|
|
|
170 `locale' property. This is so that Cygwin programs
|
|
|
171 can be run from an MS Windows native XEmacs. If not
|
|
|
172 specified, the last entry in `locale' will be used.
|
|
|
173
|
|
|
174 native-coding-system VALUE is a single coding-system expression, or a
|
|
|
175 list of such expressions. These expressions are
|
|
|
176 used to compute the operating system's native
|
|
|
177 coding system, i.e. the coding system to be used
|
|
|
178 as the alias for `native' and `file-name'. This
|
|
|
179 specifies the coding system used for text
|
|
|
180 exchanged with the operating system, such as file
|
|
|
181 names, environment variables, subprocess
|
|
|
182 arguments, etc. Each expression should be either
|
|
|
183 a symbol naming a coding system or a function
|
|
|
184 (anything that is `functionp') of one argument,
|
|
|
185 which is passed the current locale corresponding
|
|
|
186 to this language environment and should return a
|
|
|
187 coding system or nil. Each expression is tried in
|
|
|
188 turn until a coding system is obtained. If there
|
|
|
189 is no non-nil result, or no value is specified for
|
|
|
190 this property, the first coding system listed
|
|
|
191 under the `coding-system' property is used.
|
|
|
192
|
|
|
193 NOTE: This is *NOT* used under MS Windows.
|
|
|
194 Instead, `mswindows-multibyte-system-default'
|
|
|
195 is always used, since the system default code
|
|
|
196 page is what the Win32 API routines make use
|
|
|
197 of, and this cannot be changed. (We get around
|
|
|
198 this by using the Unicode versions whenever
|
|
|
199 possible -- i.e. on Windows NT/2000, and on
|
|
|
200 Windows 9x with the few API's that support
|
|
|
201 Unicode.)
|
|
|
202
|
|
|
203 mswindows-locale VALUE is an element of the form MSWINDOWS-LOCALE, or
|
|
|
204 a list of such elements. Each element is an MS
|
|
|
205 Windows locale, of the form that can be passed to
|
|
|
206 `mswindows-set-current-locale'. This property is used
|
|
|
207 both to determine the current language environment at
|
|
|
208 startup (by matching MSWINDOWS-LOCALE against the
|
|
|
209 value returned by `mswindows-user-default-locale') and
|
|
|
210 to set the values of `set-current-locale' and
|
|
|
211 `mswindows-set-current-locale' when the current
|
|
|
212 language environment is changed. (The correct CLIB
|
|
|
213 locale can always be generated by passing in the
|
|
|
214 SUBLANG, with dashes in place of underscores, or the
|
|
|
215 LANG if there's no SUBLANG. The return value will be
|
|
|
216 the canonicalized locale, in proper CLIB form.)
|
|
|
217
|
|
|
218 If there is no value for this property, the MS Windows
|
|
|
219 locale is assumed to have the same name as the
|
|
|
220 language environment."
