Control Sequence Aware Version of strwrap

Description

These functions are deprecated in favor of the strwrap_ctl flavors.

Usage

  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 an object which can be converted to a character vector by `as.character`.
`width`	a positive integer giving the target column for wrapping lines in the output.
`indent`	a non-negative integer giving the indentation of the first line in a paragraph.
`exdent`	a non-negative integer specifying the indentation of subsequent lines in paragraphs.
`prefix`, `initial`	a character string to be used as prefix for each line except the first, for which `initial` is used.
`simplify`	a logical. If `TRUE`, the result is a single character vector of line text; otherwise, it is a list of the same length as `x` the elements of which are character vectors of line text obtained from the corresponding element of `x`. (Hence, the result in the former case is obtained by unlisting that of the latter.)
`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.
`wrap.always`	TRUE or FALSE (default), whether to hard wrap at requested width if no word breaks are detected within a line. If set to TRUE then `width` must be at least 2.
`pad.end`	character(1L), a single character to use as padding at the end of each line until the line is `width` wide. This must be a printable ASCII character or an empty string (default). If you set it to an empty string the line remains unpadded.
`strip.spaces`	TRUE (default) or FALSE, if TRUE, extraneous white spaces (spaces, newlines, tabs) are removed in the same way as base::strwrap does. When FALSE, whitespaces are preserved, except for newlines as those are implicit boundaries between output vector elements.
`tabs.as.spaces`	FALSE (default) or TRUE, whether to convert tabs to spaces. This can only be set to TRUE if `strip.spaces` is FALSE.
`tab.stops`	integer(1:n) indicating position of tab stops to use when converting tabs to spaces. If there are more tabs in a line than defined tab stops the last tab stop is re-used. For the purposes of applying tab stops, each input line is considered a line and the character count begins from the beginning of the input line.
