Put function in your blogdown post's YAML header to have the packages be the packages used in your post (wrapper around funspotr::spot_pkgs()).

## Usage

spot_tags(
file_path = knitr::current_input(),
used = FALSE,
drop_knitr = FALSE,
yaml_bullet = NULL,
...
)

## Arguments

file_path

Default is the file being knitted but can change to some other file (e.g. in cases where the code for the post may reside in a different file).

used

Default is FALSE. If TRUE will pass to show_pkgs_used() rather than show_pkgs(). (Mainly useful for showing actual packages used rather than meta-packages being called like tidyverse or tidymodels. Also uses a more strict parsing method.

drop_knitr

Many blogdown posts have knitr::opts_chunk$set() in them and you may not want this tag showing-up. Default is to keep this, but set to FALSE to drop "knitr" from being tagged. yaml_bullet Default is NULL meaning that file_path is read-in and correct format is guessed based on "spot_tags" appearance with either a hyphen or bracket (corresponding with bulleted or array format in the YAML header). If it's first occurrence happens on a line that contains a bracket the value becomes FALSE else it becomes TRUE. If set to NULL and "spot_tags" is not detected at all in file_path it will default to FALSE. yaml_bullet can also be specified directly with either TRUE or FALSE. TRUE entails that spot_tags() is set in a YAML bullet, FALSE indicates the user is inputting it in an array (see examples below). See examples for how to hard-code. ... Any additional arguments to pass to spot_pkgs*(). ## Value Character vector in a format meant to be read while evaluating the YAML header when rendering. ## Details tags: - "r funspotr::spot_tags()" OR tags: ["r funspotr::spot_tags()"]  Note that you must wrap in double quotes. Thanks Yihui for getting this working and for suggesting the function! Note requires blogdown >= 1.9 to work blogdown#647. ## See also spot_pkgs(), spot_pkgs_used() ## Examples  ## To review input interactively from within rstudio you might also try: # funspotr::spot_tags(rstudioapi::getSourceEditorContext()$path)
