From 4a1fa42ccd6843dc5c1f815983ed1033aa3b75b6 Mon Sep 17 00:00:00 2001 From: Vincent Guyader Date: Thu, 23 Apr 2026 23:21:15 +0200 Subject: [PATCH 01/15] chore: run fusen::sepuku() to drop fusen workflow Removes dev/flat_*.Rmd and dev/config_fusen.yaml, strips the "Generated by {fusen}" banners from R/, tests/, and vignettes/.

It also offers dependency install helpers and `renv` integration. It can also be used outside of a package to list dependencies of arbitrary R scripts or Rmd/qmd files. + +## Common commands + +Run from the package root in an R session (the package is developed with `devtools` / `usethis` / `fusen`): + +- `devtools::load_all()` — load the in-development package. +- `devtools::document()` — regenerate `NAMESPACE` and `man/*.Rd` from roxygen. +- `devtools::test()` — run the full test suite (`tests/testthat/`). +- `testthat::test_file("tests/testthat/test-amend-description.R")` — run a single test file. The tests in `test-amend-description.R` and `test-renv_create.R` are gated on `NOT_CRAN`; to run them locally wrap with `withr::with_envvar(list("NOT_CRAN" = "true"), { ... })` as in `dev/dev_history.R`. +- `devtools::check()` — full R CMD check (also run by CI via `.github/workflows/R-CMD-check.yaml`). +- `devtools::build_vignettes()` — builds the four vignettes in `vignettes/`. +- `attachment::att_amend_desc()` — the package's own dog-food step to refresh `DESCRIPTION`; parameters are read from `dev/config_attachment.yaml` (edit that file rather than retyping arguments). + +There is no `Makefile`; `dev/dev_history.R` is the canonical scratchpad of maintainer commands (dependency refresh, CRAN prep, reverse-dep checks). + +## Architecture + +### Core function layers + +There are three layers, roughly: + +1. **Extractors** — pure functions that parse one source and return a character vector of package names. One file per source type: `att_from_namespace.R`, `att_from_rmds.R` (Rmd + qmd), `att_from_rscripts.R`, `att_from_examples.R`, `att_from_data.R`, `att_from_description.R`. These can be called standalone, outside a package. +2. **DESCRIPTION writers** — `att_to_description.R` (despite the filename, this is where `att_amend_desc()` / `att_to_desc_from_pkg()` / `att_to_desc_from_is()` live — this is the biggest file in the package at ~450 lines and orchestrates all the extractors) and `set_remotes.R` (fills `Remotes:` by inspecting locally-installed packages via `find_remotes()`). +3. **Config, install, renv helpers** — `amend_with_config.R` (load/save/compare `dev/config_attachment.yaml`), `install_from_description.R`, `create_dependencies_file.R` + `dependencies_file_text.R` (emit `inst/dependencies.R`), `create_renv.R` (generate dev/prod `renv` lockfiles). + +The typical user entry point is `att_amend_desc()`: it calls extractors on each directory, unions the results, classifies into `Imports` vs `Suggests` based on which directory the package was found in, and rewrites `DESCRIPTION` via the `{desc}` package. + +### Config-driven parameter loading + +`att_amend_desc()` has many arguments (ignore lists, extra suggests, dir overrides). `amend_with_config.R` implements a three-way reconcile between (a) arguments passed by the user, (b) previously-saved values in `dev/config_attachment.yaml`, and (c) function defaults. If the user passes non-default args that also differ from the saved config, it errors and asks the user to pick `update.config = TRUE` or `use.config = FALSE`. When adding a new argument to `att_amend_desc()`, you must also: add it to the `local_att_params` list inside the function, and make sure `save_att_params()`/`load_att_params()` round-trip it. + +### Test fixtures + +`inst/dummypackage/` is a minimal fake R package used as the fixture for most tests (and README examples). Tests copy it into `tempfile()` before mutating it — preserve that pattern for new tests so they stay hermetic. There is also `inst/dummyfolder/` for non-package script tests, and a collection of `f*.R` / `*.Rmd` / `*.qmd` files under `tests/testthat/` that are raw parse targets for the extractors (not test scripts themselves — they have no `test_that`). + +## Conventions + +- Tidyverse style guide, roxygen2 with markdown (`Roxygen: list(markdown = TRUE)` in `DESCRIPTION`). +- User-facing changes go in a new bullet at the top of `NEWS.md` under the current development version header. +- New exports must be declared via `@export` roxygen tags; `NAMESPACE` is regenerated, not hand-edited. +- `dev/` is `.Rbuildignore`d — it is developer-only and not shipped to CRAN. diff --git a/R/amend_with_config.R b/R/amend_with_config.R index f4c1193..d4e1675 100644 --- a/R/amend_with_config.R +++ b/R/amend_with_config.R @@ -1,4 +1,3 @@ -# WARNING - Generated by {fusen} from dev/flat_save_att_params.Rmd: do not edit by hand #' Compare input from the user to config file or default inputs #' diff --git a/R/create_dependencies_file.R b/R/create_dependencies_file.R index ce5b610..6f2058a 100644 --- a/R/create_dependencies_file.R +++ b/R/create_dependencies_file.R @@ -1,4 +1,3 @@ -# WARNING - Generated by {fusen} from dev/flat_create_dependencies_file.Rmd: do not edit by hand #' Create the list of instructions to install dependencies from a DESCRIPTION file #' diff --git a/R/dependencies_file_text.R b/R/dependencies_file_text.R index 216ed2c..a930a2d 100644 --- a/R/dependencies_file_text.R +++ b/R/dependencies_file_text.R @@ -1,4 +1,3 @@ -# WARNING - Generated by {fusen} from dev/flat_create_dependencies_file.Rmd: do not edit by hand #' dependencies_file_text #' diff --git a/dev/config_fusen.yaml b/dev/config_fusen.yaml deleted file mode 100644 index 61eb94e..0000000 --- a/dev/config_fusen.yaml +++ /dev/null @@ -1,24 +0,0 @@ -flat_create_dependencies_file.Rmd: - path: dev/flat_create_dependencies_file.Rmd - state: active - R: - - R/create_dependencies_file.R - - R/dependencies_file_text.R - tests: - - tests/testthat/test-dependencies_file_text.R - - tests/testthat/test-create_dependencies_file.R - vignettes: vignettes/create-dependencies-file.Rmd - inflate: - flat_file: dev/flat_create_dependencies_file.Rmd - vignette_name: Create dependencies file - open_vignette: false - check: false - document: true - overwrite: 'yes' - clean: ask -flat_save_att_params.Rmd: - path: dev/flat_save_att_params.Rmd - state: active - R: R/amend_with_config.R - tests: tests/testthat/test-amend_with_config.R - vignettes: [] diff --git a/dev/flat_create_dependencies_file.Rmd b/dev/flat_create_dependencies_file.Rmd deleted file mode 100644 index 88e2083..0000000 --- a/dev/flat_create_dependencies_file.Rmd +++ /dev/null @@ -1,368 +0,0 @@ ---- -title: "flat_create_dependencies_file.Rmd empty" -output: html_document -editor_options: - chunk_output_type: console ---- - -```{r development, include=FALSE} -library(testthat) -``` - -```{r development-load} -# Load already included functions if relevant -pkgload::load_all(export_all = FALSE) -``` - - -```{r function-dependencies_file_text} -#' dependencies_file_text -#' -#' Create the text of create_dependencies_file() -#' -#' @param ll a vector of all packages -#' @param remotes_orig a vector of remotes -#' @param install_only_if_missing Logical Modify the installation instructions to check, beforehand, if the packages are missing .

This closes several gaps reported on GitHub: - #120/#132: false positives from `::` inside string literals or comments (xpath `following-sibling::td`, CSS `label::after`, `sprintf('%s::plot()', ...)`) are now ignored. - #128: `use("pkg", ...)` (R >= 4.4) is now detected. - #129: named-arg forms are supported: `library(package = "pkg")`, `require(lib.loc = ..., package = ...)`, `requireNamespace("pkg", lib.loc = ...)`, `getFromNamespace("fn", "pkg")`, `loadNamespace()`, `asNamespace()`, `attachNamespace()`, `getNamespace()`, `packageVersion()`. Fixture `tests/testthat/f_edge_cases.R` and new test file `tests/testthat/test-edge-cases.R` document the cases.

The previous walker crashed with `argument "el" is missing, with no default` on any script containing them, which meant most real R files silently fell back to the legacy regex detector. A new `walk_elem()` helper inspects each sub-expression as a promise and skips empty symbols without forcing them into a local binding. - `att_from_rscript()` gains an `encoding` argument (default `getOption("encoding")`) instead of hardcoding UTF-8. Avoids a regression for Latin-1 / Windows-1252 scripts on Windows. - Restrict `pkg_intro_calls` to the documented set (`library`, `require`, `requireNamespace`, `loadNamespace`, `use`, `getFromNamespace`). `packageVersion()`, `getNamespace()`, `asNamespace()`, `attachNamespace()` are intentionally *not* treated as dependency introducers — they are commonly used for feature detection and would otherwise silently expand `Imports`. - Emit a `warning()` when the AST parser fails and we fall back to the legacy regex detector, naming the offending file. Broken scripts are no longer silently degraded. - Replace `expect_silent()` around `att_from_rmd()` with explicit type and length assertions, and verify the `knitr::opts_knit` auto-detect expression directly rather than re-running the purl pipeline through `system()`. The previous tests were flaky on CI because knitr/purl and `system()` both write to stdout. - Update `test-rscript.R` expectation for `escape_newline.R`: the former assertion (`c("rmarkdown", "glue", "knitr")`) relied on regex false positives inside glue string literals. With AST detection, only `glue` is a real call (via `glue::glue_collapse`); the other two must not be detected.
