In r-lib/pkgman: Another Approach to Package Installation

Match system requirement descriptions to the database

Description

In the usual workflow pak matches the SystemRequirements fields of the DESCRIPTION files to the database.

Usage

sysreqs_db_match(specs, sysreqs_platform = NULL)

Arguments

specs	Character vector of system requirements descriptions.
sysreqs_platform	System requirements platform. If NULL, then the sysreqs_platform \evalman_config_link("configuration option") is used, which defaults to the current platform. Set this option if \eval.packageName does not detect your platform correctly.

Details

The sysreqs_db_match() function lets you match any string, and it is mainly useful for debugging.

Value

Data frame with columns:

• spec: the input specs.

• sysreq: name of the system library or tool.

• packages: system packages, list column of character vectors. Rarely it can be an empty string, e.g. if a pre_install script performs the installation.

• pre_install: list column of character vectors. Shell script(s) to run before the installation.

• post_install: list column of character vectors. Shell script(s) to run after the installation.
