Check for Presence of Control Sequences

Description

This function is deprecated in favor of the strsplit_ctl.

Usage

strsplit_sgr(
  x,
  split,
  fixed = FALSE,
  perl = FALSE,
  useBytes = FALSE,
  warn = getOption("fansi.warn", TRUE),
  term.cap = getOption("fansi.term.cap", dflt_term_cap()),
  normalize = getOption("fansi.normalize", FALSE),
  carry = getOption("fansi.carry", FALSE),
  terminate = getOption("fansi.terminate", TRUE)
)

Arguments

`x`	a character vector, or, unlike `base::strsplit` an object that can be coerced to character.
`split`	character vector (or object which can be coerced to such) containing regular expression(s) (unless `fixed = TRUE`) to use for splitting. If empty matches occur, in particular if `split` has length 0, `x` is split into single characters. If `split` has length greater than 1, it is re-cycled along `x`.
`fixed`	logical. If `TRUE` match `split` exactly, otherwise use regular expressions. Has priority over `perl`.
`perl`	logical. Should Perl-compatible regexps be used?
`useBytes`	logical. If `TRUE` the matching is done byte-by-byte rather than character-by-character, and inputs with marked encodings are not converted. This is forced (with a warning) if any input is found which is marked as `"bytes"` (see `Encoding`).
`warn`	TRUE (default) or FALSE, whether to warn when potentially problematic Control Sequences are encountered. These could cause the assumptions `fansi` makes about how strings are rendered on your display to be incorrect, for example by moving the cursor (see `?fansi`). At most one warning will be issued per element in each input vector. Will also warn about some badly encoded UTF-8 strings, but a lack of UTF-8 warnings is not a guarantee of correct encoding (use `validUTF8` for that).
`term.cap`	character a vector of the capabilities of the terminal, can be any combination of "bright" (SGR codes 90-97, 100-107), "256" (SGR codes starting with "38;5" or "48;5"), "truecolor" (SGR codes starting with "38;2" or "48;2"), and "all". "all" behaves as it does for the `ctl` parameter: "all" combined with any other value means all terminal capabilities except that one. `fansi` will warn if it encounters SGR codes that exceed the terminal capabilities specified (see `term_cap_test` for details). In versions prior to 1.0, `fansi` would also skip exceeding SGRs entirely instead of interpreting them. You may add the string "old" to any otherwise valid `term.cap` spec to restore the pre 1.0 behavior. "old" will not interact with "all" the way other valid values for this parameter do.
`normalize`	TRUE or FALSE (default) whether SGR sequence should be normalized out such that there is one distinct sequence for each SGR code. normalized strings will occupy more space (e.g. "\033[31;42m" becomes "\033[31m\033[42m"), but will work better with code that assumes each SGR code will be in its own escape as `crayon` does.
`carry`	TRUE, FALSE (default), or a scalar string, controls whether to interpret the character vector as a "single document" (TRUE or string) or as independent elements (FALSE). In "single document" mode, active state at the end of an input element is considered active at the beginning of the next vector element, simulating what happens with a document with active state at the end of a line. If FALSE each vector element is interpreted as if there were no active state when it begins. If character, then the active state at the end of the `carry` string is carried into the first element of `x` (see "Replacement Functions" for differences there). The carried state is injected in the interstice between an imaginary zeroeth character and the first character of a vector element. See the "Position Semantics" section of `substr_ctl` and the "State Interactions" section of `?fansi` for details. Except for `strwrap_ctl` where `NA` is treated as the string `"NA"`, `carry` will cause `NA`s in inputs to propagate through the remaining vector elements.
`terminate`	TRUE (default) or FALSE whether substrings should have active state closed to avoid it bleeding into other strings they may be prepended onto. This does not stop state from carrying if `carry = TRUE`. See the "State Interactions" section of `?fansi` for details.
