0ae8ebe8 GM |
138 | "Function to indent the arguments of a Lisp function call. |
139 | This is suitable for use as the value of the variable | |
140 | `lisp-indent-function'. INDENT-POINT is the point at which the | |
141 | indentation function is called, and STATE is the | |
142 | `parse-partial-sexp' state at that position. Browse the | |
143 | `lisp-indent' customize group for options affecting the behavior | |
144 | of this function. | |
145 | ||
146 | If the indentation point is in a call to a Lisp function, that | |
147 | function's common-lisp-indent-function property specifies how | |
148 | this function should indent it. Possible values for this | |
149 | property are: | |
150 | ||
151 | * defun, meaning indent according to `lisp-indent-defun-method'; | |
152 | i.e., like (4 &lambda &body), as explained below. | |
153 | ||
154 | * any other symbol, meaning a function to call. The function should | |
155 | take the arguments: PATH STATE INDENT-POINT SEXP-COLUMN NORMAL-INDENT. | |
156 | PATH is a list of integers describing the position of point in terms of | |
157 | list-structure with respect to the containing lists. For example, in | |
158 | ((a b c (d foo) f) g), foo has a path of (0 3 1). In other words, | |
159 | to reach foo take the 0th element of the outermost list, then | |
160 | the 3rd element of the next list, and finally the 1st element. | |
161 | STATE and INDENT-POINT are as in the arguments to | |
162 | `common-lisp-indent-function'. SEXP-COLUMN is the column of | |
163 | the open parenthesis of the innermost containing list. | |
164 | NORMAL-INDENT is the column the indentation point was | |
165 | originally in. This function should behave like `lisp-indent-259'. | |
166 | ||
167 | * an integer N, meaning indent the first N arguments like | |
168 | function arguments, and any further arguments like a body. | |
169 | This is equivalent to (4 4 ... &body). | |
170 | ||
171 | * a list. The list element in position M specifies how to indent the Mth | |
172 | function argument. If there are fewer elements than function arguments, | |
173 | the last list element applies to all remaining arguments. The accepted | |
174 | list elements are: | |
175 | ||
176 | * nil, meaning the default indentation. | |
177 | ||
178 | * an integer, specifying an explicit indentation. | |
179 | ||
180 | * &lambda. Indent the argument (which may be a list) by 4. | |
181 | ||
182 | * &rest. When used, this must be the penultimate element. The | |
183 | element after this one applies to all remaining arguments. | |
184 | ||
185 | * &body. This is equivalent to &rest lisp-body-indent, i.e., indent | |
186 | all remaining elements by `lisp-body-indent'. | |
187 | ||
188 | * &whole. This must be followed by nil, an integer, or a | |
189 | function symbol. This indentation is applied to the | |
190 | associated argument, and as a base indent for all remaining | |
191 | arguments. For example, an integer P means indent this | |
192 | argument by P, and all remaining arguments by P, plus the | |
193 | value specified by their associated list element. | |
194 | ||
195 | * a symbol. A function to call, with the 6 arguments specified above. | |
196 | ||
197 | * a list, with elements as described above. This applies when the | |
198 | associated function argument is itself a list. Each element of the list | |
199 | specifies how to indent the associated argument. | |
200 | ||
201 | For example, the function `case' has an indent property | |
202 | \(4 &rest (&whole 2 &rest 1)), meaning: | |
203 | * indent the first argument by 4. | |
204 | * arguments after the first should be lists, and there may be any number | |
205 | of them. The first list element has an offset of 2, all the rest | |
206 | have an offset of 2+1=3." | |
