Replaces the lines between <!-- BEGIN name --> and <!-- END name -->
with lines, surrounded by a blank line on each side. The markers are kept,
so repeated calls with the same lines leave the file unchanged.
Usage
replace_block(path, name, lines, write = TRUE)
Arguments
- path
Path to the file.
- name
Marker name. Each marker must occur exactly once, BEGIN before
END, or the call is an error.
- lines
Character vector of replacement lines.
- write
If FALSE, report whether the file would change without
writing it, as a staleness check needs.
Value
TRUE if the file changed (or would change), otherwise FALSE.
