|

107
|

155
|
108 coding-system: list of coding systems specific to the langauge.
|
|
197
|
109
|
|
155
|
110 tutorial: a tutorial file name written in the language.
|
|
197
|
111
|
|
155
|
112 sample-text: one line short text containing characters of the language.
|
|
197
|
113
|
|
|
114 documentation: t or a string describing how Emacs supports the language.
|
|
|
115 If a string is specified, it is shown before any other information
|
|
|
116 of the language by the command `describe-language-environment'.
|
|
|
117
|
|
165
|
118 setup-function: a function to call for setting up environment
|
|
197
|
119 convenient for a user of the language.
|
|
155
|
120
|
|
197
|
121 If KEY is documentation or setup-function, you can also specify
|
|
|
122 a cons cell as INFO, in which case, the car part should be
|
|
|
123 a normal value as INFO for KEY (as described above),
|
|
|
124 and the cdr part should be a symbol whose value is a menu keymap
|
|
|
125 in which an entry for the language is defined. But, only the car part
|
|
|
126 is actually set as the information.
|
|
|
127
|
|
|
128 We will define more KEYs in the future. To avoid conflict,
|
|
|
129 if you want to use your own KEY values, make them start with `user-'."
