Crosspost a blog post directory to one or more other repositories

Usage

crosspost_blog(post = getwd(), destinations, root = NULL, overwrite = FALSE)

Arguments

post: Path to the blog post folder to copy. Defaults to the current working directory, i.e. run this from inside the blog post's own folder.
destinations: A named character vector/list of destination directories, one per target repo, e.g. c(nasa = "NASA-Openscapes.github.io/news", nmfs = "nmfs-openscapes.github.io/blog"). The post folder is copied *into* each of these directories, keeping its original folder name. Entries can be relative (resolved against `root`) or absolute paths (used as-is, e.g. a repo cloned somewhere else).
root: Optional common parent folder that all repos live under, e.g. "~/github/repos/openscapes". Relative entries in `destinations` are resolved against this. Ignored for destinations that are already absolute paths.
overwrite: If FALSE (default), errors when a destination already has a folder for this post. If TRUE, replaces it.

Value

Invisibly, the full paths the post was copied to.

Examples

if (FALSE) { # \dontrun{
# All repos as siblings under one common folder (e.g. github/repos/openscapes/):
# only relative subpaths need to be given, resolved against `root`.
crosspost_blog(
  post = "website-new/blog/2026-09-09-openscapes_esip_summer_2026",
  root = "~/Documents/repos/github/openscapes/crossposting",
  destinations = c(
    nasa = "NASA-Openscapes.github.io/news",
    nmfs = "nmfs-openscapes.github.io/blog"
  )
)

# A destination cloned somewhere else entirely can be given as an absolute
# path, bypassing `root`:
crosspost_blog(
  post = "website-new/blog/2026-09-09-openscapes_esip_summer_2026",
  root = "~/Documents/repos/github/openscapes/crossposting",
  destinations = c(
    nasa = "NASA-Openscapes.github.io/news",
    nmfs = "/some/other/place/nmfs-openscapes.github.io/blog"
  )
)
} # }
