Print interactive outline of file sections

The outline functions return a data frame that contains details of file location.

It also includes a print method that will provide a console output that will include clickable hyperlinks in RStudio (or if your terminal supports it). It works with both (qR)md and R files.

Outline elements include

Any code section
function definition (not shown in console by default)
TODO items
Parse cli hyperlinks
Plot or table titles
FIgures caption in Quarto documents (limited support for multiline caption currently)
test names
Indicator of recent modification
Colored output for
URL and gh issue detection and link creation.

By default

file_outline() prints the outline the active document if in RStudio
proj_outline() prints the outline of the active project if in RStudio
dir_outline() prints the outline of the active working directory by default or

Usage

file_outline(
  path = active_rs_doc(),
  pattern = NULL,
  alpha = FALSE,
  print_todo = TRUE,
  recent_only = FALSE
)

proj_outline(
  path = active_rs_proj(),
  pattern = NULL,
  dir_tree = FALSE,
  alpha = FALSE,
  recent_only = FALSE
)

dir_outline(
  path = ".",
  pattern = NULL,
  dir_tree = FALSE,
  alpha = FALSE,
  recent_only = FALSE,
  recurse = FALSE
)

Arguments

path: A character vector of file paths, a project. Defaults to the active file, project or directory.
pattern: A string or regex to search for in the outline. If specified, will search only for elements matching this regular expression. The print method will show the document title for context. Previously regex_outline
alpha: Whether to show in alphabetical order
print_todo: Should include TODOs in the file outline? If FALSE, will print a less verbose output with sections.
recent_only: Show outline for recent files
dir_tree: If TRUE, will print the fs::dir_tree() or non-R files in the directory
recurse: If TRUE recurse fully, if a positive number the number of levels to recurse.

Value

A outline_report object that contains the information. Inherits tbl_df.

A symbol will show for recently modified files.

Details

proj_outline() and dir_outline() are wrapper of file_outline().

In proj_outline(), path accepts project names, see proj_list() for how to set up reuseme to regognize your projects' locations.

The parser is very opinionated and is not very robust as it is based on regexps. For a better file parser, explore other options, like lightparser for Quarto, {roxygen2}

Will show TODO items and will offer a link to mark them as complete.

Note that proj_outline() strips some test files from the outline, as example test files (like in usethis repo) don't help understand a project's outline. Use dir_outline(recurse = TRUE) to make sure these are included in your outline.

Examples

file <- fs::path_package("reuseme", "example-file", "outline-script.R")
file_outline(file)
#> 
#> ── `example-file/outline-script.R`  Example for `file_outline()` 
#> `i` Load packages
#> `i` Wrangle + visualize data
#> `i` A great title
#> `i` TODO improve this Viz!

# Remove todo items
file_outline(file, print_todo = FALSE, alpha = TRUE)
#> 
#> ── `example-file/outline-script.R`  Example for `file_outline()` 
#> `i` A great title
#> `i` Load packages
#> `i` Wrangle + visualize data
