Rename files and/or directories using a syntactic naming function

Usage

syntacticRename(
  path,
  recursive = FALSE,
  fun = c("kebabCase", "snakeCase", "camelCase", "upperCamelCase"),
  quiet = FALSE,
  dryRun = FALSE
)

Arguments

path: character. File and/or directory paths.
recursive: logical(1). Should the function recurse into directories?
fun: character(1). Function name.
quiet: logical(1). Perform command quietly, suppressing messages.
dryRun: logical(1). Return the proposed file path modifications without modification.

Value

list. Named list containining from and to rename operations.

Details

Intelligently deals with a case-insensitive file system, if necessary. This is very useful for macOS and Windows.

Our syntactic naming functions can result in changes that only differ in case, which are problematic on case-insensitive mounts, and require movement of the files into a temporary file name before the final rename.

Examples

testdir <- AcidBase::tempdir2()
from <- file.path(testdir, c("helloWorld.txt", "fooBar.R"))
file.create(from)
#> [1] TRUE TRUE
print(basename(from))
#> [1] "helloWorld.txt" "fooBar.R"      
output <- syntacticRename(from)
