$c-continue(5)

NAME

$c-continue - C-mode; line continuation indent
$c-contmax - C-mode; line continuation maximum indent

SYNOPSIS

$c-continue integer; Default is 10
-n <= integer <= n

$c-contmax integer; Default is 16
-n <= integer <= n

DESCRIPTION

$c-continue and $c-contmax are part of the cmode(2m) environment for C programmers.

$c-continue sets the indent to be added to a split line, i.e. for an indent of 20, a continued statement would be indented to 30. A continued statement is a single c statement which is spread over 2 or more lines, the 2nd and any following lines would be indented to 30. For example

        thisIsAVeryLongVariableWhichMeansAssignmentsAreSplit = 
                  ThisIsTheFirstContinuedStatementLine + 
                  ThisIsTheSecondContinuedStatementLine + etc ; 

The indent is changed if there is an open bracket, continued statements are indented to the depth of the open bracket plus one, e.g.

        func(firstFuncArg, 
             secondFuncArg, 
             anotherBracketForFun(firstAnotherBracketForFunArg, 
                                  secondAnotherBracketForFunArg), 
             thirdFuncArg) ; 

$c-contmax sets an upper limit of the indentation where an open bracket is encountered, in the case where the leading indent of the function name and open bracket exceeds $c-contmax, then the continuation is reduced to the continuation indent.

The effect of $c-contmax is described as follows; if $c-contmax is set to a large value then the default open brace offset appearence is:-

longVariable = LongFunctionNameWhichMeans(isSoFar, 
                                          OverAndYouRunOutOfRoom) ; 

Setting $c-contmax to 16 gives:

longVariable = LongFunctionNameWhichMeans(isSoFar, 
                overAndYouRunOutOfRoom) ; 

Where by the second argument indent has been artificially reduced because of it's length.
