Changelog

Source: NEWS.md

command 0.3.0

Variable-length file arguments

• Added cmd_assign_collect() and cmd_assign_collect_quiet(), which assign every unnamed command-line argument to the one argument that was not passed by name.
• extract_make(), extract_shell(), makefile(), and shell_script() read calls to cmd_assign_collect(). A character vector of paths becomes one file name per element, and in a Makefile the last element is the target.
• extract_make(), extract_shell(), makefile(), and shell_script() now recognize cmd_assign_quiet(), cmd_assign_collect_quiet(), and a call written with a command:: or command::: prefix.
• The dot-name convention for file arguments has been documented in the help for cmd_assign() and cmd_assign_collect().
• shell_script() orders commands by matching output paths with input paths.
• cmd_assign() and cmd_assign_collect() reject a named command-line argument that is passed more than once.
• makefile(), shell_script(), extract_make(), and extract_shell() read literal values from calls. A name or a function call such as file.path() or paste() is an error.

Command-line values

• A named argument is split on the first =, so the value may itself contain =. An argument with an empty name, such as --=value, is an error.

Shell commands

• extract_shell() and shell_script() leave a plain length-1 vector unchanged, and quote a path or value only when it contains a space or a character that is special to the shell. NULL is written as --name=NULL.
• shell_script() rejects a quiet value that is not TRUE or FALSE.

Bug fixes

• The message for a missing directory now says that the directory does not exist.

Documentation

• Revised the package description and the help pages.

command 0.2.0

CRAN release: 2026-07-23

Dependence on ‘fs’ package (#8)

• Removed dependence on fs package

Handling of empty strings (#6)

• Empty command line values like --v= (from an undefined Make variable) are now an error unless the corresponding cmd_assign() argument is character
• When an empty string is assigned, the message notes that the value is an empty string

Paths

• extract_make() and extract_shell() no longer prefix relative paths with ./

DESCRIPTION and package help (#5)

• Revised descriptions, and removed internal keyword from command-package.R.

renv (#7)

• Added use_renv(), which activates a renv project at the start of scripts run with Rscript (which skips .Rprofile).
• Added article “Using command with renv”

command 0.1.4

• Added test coverage

command 0.1.3

CRAN release: 2025-11-22

Documentation

• Tidied articles, and added detail on the way that extract_make() and extract_shell() treat dotted vs non-dotted arguments.

Bug fixes

• Fixed bug in extract_shell(), extract_make(), shell_script(), and makefile() where the shell commands or Makefile rules created by these function used absolute paths to R scripts, rather than relative paths.

command 0.1.2

CRAN release: 2025-10-16

• Expanded description and provided options to turn off messages.

command 0.1.0

• Initial CRAN submission.
