In rappster/descriptionr: Extended processing features for package DESCRIPTION files

descriptionr (v0.1.3)

Processing of package DESCRIPTION files

Installation

require("devtools")
devtools::install_github("Rappster/conditionr")
devtools::install_github("Rappster/descriptionr")
require("descriptionr")

Quick intro

For a package project loaded via devtools::load_all() and assuming that the current working directory corresponds to the package project's root directory:

getPackageDescription()
## Alternative way:
getPackageDescription(from = getwd())
getPackageDescription(from = file.path(getwd(), "DESCRIPTION"))
## --> this would actually call `getPackageDescriptionFromFile()`

getPackageDescription(fields = "Date")
getPackageDescription(fields = "Nonexisting")

For a loaded package:

require("devtools")
getPackageDescription(from = "devtools")
## Alternative way:
getPackageDescription(from = file.path(.libPaths()[1], "devtools"))
getPackageDescription(from = file.path(.libPaths()[1], "devtools/DESCRIPTION"))
## --> this would actually call `getPackageDescriptionFromFile()`

getPackageDescription(from = "devtools", fields = "Built")
