Description

Usage
drake_meta(target, config)
Arguments
target |
Character scalar, name of the target to get metadata. |
config |
Top-level internal configuration list produced

Details
The metadata helps determine if the
target is up to date or outdated. The metadata of imports
is used to compute the metadata of targets.
Target metadata is computed with drake_meta()
, and then
drake:::store_outputs()
completes the metadata
after the target is built.
In other words, the output of drake_meta()
corresponds
to the state of the target immediately before make()
builds it.
See diagnose()
to read the final metadata of a target,
including any errors, warnings, and messages in the last build.
Value
A list of metadata on a target. Does not include
the file modification time if the target is a file.
That piece is computed later in make()
by
drake:::store_outputs()
.
