grepl_text_files: Find Files with Text that Matches a Pattern
In patelm9/cave: Package Management Package

Find files in a path that contains text that matches a pattern. The files in the given path can also be optionally subset based on a pattern of its own before the files are read into the caller environment, useful feature for cases where the path contains a mix of different file types and only text files need to be read.

grepl_text_files(
  path = ".",
  file_pattern = NULL,
  all.files = FALSE,
  recursive = FALSE,
  text_pattern,
  ignore.case = TRUE,
  perl = FALSE,
  fixed = FALSE,
  useBytes = FALSE
)

`path`	a character vector of full path names; the default corresponds to the working directory, `getwd()`. Tilde expansion (see `path.expand`) is performed. Missing values will be ignored. Elements with a marked encoding will be converted to the native encoding.
`all.files`	a logical value. If `FALSE`, only the names of visible files are returned. If `TRUE`, all file names will be returned.
`recursive`	logical. Should the listing recurse into directories?
`ignore.case`	if `FALSE`, the pattern matching is case sensitive and if `TRUE`, case is ignored during matching.
`perl`	logical. Should Perl-compatible regexps be used?
`fixed`	logical. If `TRUE`, `pattern` is a string to be matched as is. Overrides all conflicting arguments.
`useBytes`	logical. If `TRUE` the matching is done byte-by-byte rather than character-by-character. See ‘Details’.
