This takes in a vector of files and compares them against a text database of files with checksums. It's been heavily adapted from blogdown to provide utilities for removal and updating of the old database.
build_status( sources, db = "site/built/md5sum.txt", rebuild = FALSE, write = FALSE )
a character vector of ALL source files OR a single file to be rebuilt. These must be absolute paths
the path to the database
if the files should be rebuilt, set this to TRUE (defaults to FALSE)
if TRUE, the database will be updated, Defaults to FALSE, meaning that the database will remain the same.
If you supply a single file into this function, we assume that you want that
one file to be rebuilt, so we will always return that file in the
element and update the md5 sum in the database (if it has changed at all).
If you supply multiple files, you are indicating that these are the only files you care about and the database will be updated accordingly, removing entries missing from the sources.
a list of the following elements
build absolute paths of files to build
new a new data frame with three columns:
file the relative path to the source file
checksum the md5 sum of the source file
built the relative path to the built file
remove absolute paths of files to remove. This will be missing if there is nothing to remove
old old database (for debugging). This will be missing if there is no old database or if a single file was rebuilt.
