C Mode facilitates the editing of C files. Much of the latter part of the
development of the jed editor was done using this mode. This mode may be
customized by a judicious choice of the variables C_INDENT and
C_BRACE as well as the bindings of the curly brace keys {
and }. Experiment to find what you like or write your own using the
S-Lang interface.
By default, the ENTER key is bound to the function
newline_and_indent. This does what its name suggests: inserts a
newline and indents. Again, some modes may rebind this key. In addition,
the keys {, }, and TAB are also special in this mode.
The TAB key indents the current line and the { and }
keys insert themselves and reindent. If you do not like any of these
bindings, simply rebind the offending one to self_insert_cmd.
Finally, the key sequence ESC ; is bound to a function called
c_make_comment. This function makes and indents a C comment to the
column specified by the value of the variable C_Comment_Column. If
a comment is already present on the line, it is indented.
