These changes make it easier for others to extend usethis, i.e. to create workflow packages specific to their organization, or to use usethis in other packages.
proj_path() is newly exported. Use it to build paths within the active project. Like
proj_set(), it is not aimed at end users, but rather for use in extension packages. End users should use rprojroot or its simpler companion, here, to programmatically detect a project and build paths within it (#415, #425).
getOption("usethis.quiet") is consulted when printing user-facing messages. Set this option to
TRUE to suppress output, e.g., to use usethis functions quietly in another package. For example, use
withr::local_options(list(usethis.quiet = TRUE)) in the calling function (#416, #424).
proj_sitrep() reports current working directory, the active usethis project, and the active RStudio Project. Call this function if things seem weird and you’re not sure what’s wrong or how to fix it. Designed for interactive use and debugging, not for programmatic use (#426).
usethis has a new logo! (#429)
use_github() fails earlier, with a more informative message, in the absence of a GitHub personal access token (PAT). Also looks for the PAT more proactively in the usual environment variables (i.e., GITHUB_PAT, GITHUB_TOKEN) (#320, #340, @cderv).
The logic for setting DESCRIPTION fields in
use_description() got a Spring Cleaning. Fields directly specified by the user take precedence, then the named list in
getOption("usethis.description") is consulted, and finally defaults built into usethis.
use_description_defaults() is a new function that reveals fields found in options and built into usethis. Options specific to one DESCRIPTION field, e.g.
devtools.desc.license, are no longer supported. Instead, use a single named list for all fields, preferably stored in an option named
"devtools.desc" is still consulted for backwards compatibility). (#159, #233, #367)
edit_*() functions now return the target path, invisibly (#255).
edit_git_ignore(scope = "user") prefers
~/.gitignore, but detects an existing
~/.gitignore_global, if it exists. If a new global gitignore file is created, it is created as
~/.gitignore and recorded in user’s git config as the
create_from_github() gains several arguments and new functionality. The
protocol argument lets user convey whether remote URLs should be ssh or https. In the case of “fork and clone”, the original repo is added as
upstream remote. It is now possible – although rarely necessary – to directly specify the GitHub PAT, credentials (in git2r form), and GitHub host (#214, #214, #253).
use_github_labels() can create or update the colour of arbitrary GitHub issue labels, defaulting to a set of labels and colours used by the tidyverse packages, which are now exposed via
tidy_labels(). That set now includes the labels “good first issue” and “help wanted” (#168, #249).
browse_github_pat() goes to the webpage where a GitHub user can create a personal access token (PAT) for the GitHub API. If the user configures a PAT, they can use functions like
use_github() to easily create and connect GitHub repos to local projects. (#248, #257, @jeroen, via @jennybc).
use_tidy_github() creates a standard set of files that make a GitHub repository more navigable for users and contributors: an issue template, contributing guidelines, support documentation, and a code of conduct. All are now placed in a
.github/ subdirectory (#165, @batpigandme).
use_course() downloads a folder’s worth of materials from a ZIP file, with deliberate choices around the default folder name and location. Developed for use at the start of a workshop. Helps participants obtain materials from, e.g., a DropBox folder or GitHub repo (#196).
use_blank_slate() provides a way to opt in to an RStudio workflow where the user’s workspace is neither saved nor reloaded between R sessions. Automated for
scope = "project". Provides UI instructions for
scope = "user", for now (#139).
New projects that don’t exhibit other obvious criteria for being a “project” will include a sentinel, empty file named
.here, so they can be recognized as a project.
Substantial increase in unit test coverage.
use_tidy_versions() sets minimum version requirement for all dependencies.
This is a new package that extracts out many functions that previously lived in devtools, as well as providing more building blocks so you can create your own helpers. As well as the many new helpers listed below, there are three main improvements to the package:
usethis is gradually evolving towards supporting more general R “projects”, not just packages. This is still a work in progress, so please let me know if you use a function that you think should work with projects but doesn’t. You can also try out the new
create_project() which creates a basic RStudio project.
The concept of the working directory and the “base path” have been refined. Rather than using an argument to specify the active project, all
use_ functions now use a global active project setting, as returned by
proj_get(). This is cached throughout a session, although it will be updated by
create_project(). You’ll now get an clear error if you attempt to
use_something() outside of a project, and
create_something() will warn if you’re trying to create inside an existing project.
The output from all usethis commands has been reviewed to be informative but not overwhelming. usethis takes advantage of colour (using crayon and RStudio 1.1) to help chunk the output and clearly differentiate what you need to do vs. what has been done for you.
use_apl2_license() if you want to use the Apache 2.0 license.
use_tidy_description() puts description fields in a standard order and alphabetises dependencies.
use_usethis() opens your
.Rprofile and gives you the code to copy and paste in.
A new class of functions make it easy to edit common config files:
The license functions (
use_gpl3_license()) save a copy of the standard license text in
LICENSE.md, which is then added to
.Rbuildignore. This allows you to follow standard licensing best practices while adhering to CRANs requirements (#10).
use_package_doc() uses more modern roxygen2 template requires that less duplication.
use_readme_rmd() now puts images in
man/figures/ and no longer adds to
.Rbuildgnore. This ensures that the rendered
README.md will also work on CRAN (#16, #19). The first chunk now uses
include = FALSE and is named setup (#19).
Functions which require code to be copied now automatically put the code on the clipboard if it is available (#52).
create_package()no longer creates a dependency on the current version of
use_build_ignore() now strips trailing
