A rule that defines a dependency between targets without actually providing any execution script.

This rule is useful when you want to specify that a target depends on another target but you do not want to execute any script to build it.

Usage

depRule(target, depends = NULL, task = "all")

Arguments

target

Target file name that depends on depends

depends

A character vector of prerequisite file names that target depends on.

task

A character vector of parent task names. The mechanism of tasks allows grouping rules. Anything different from 'all' will cause the creation of a new task depending on the given rule. Executing make taskname will then force building this rule.

Value

Instance of S3 class rmake.rule
