\title{Concatenate Strings in a List}
\usage{
stri_join_list(x, sep = "", collapse = NULL)

stri_c_list(x, sep = "", collapse = NULL)

stri_paste_list(x, sep = "", collapse = NULL)
}
\arguments{
\item{x}{a list consisting of character vectors}

\item{sep}{a single string; separates strings in each of the character
vectors in \code{x}}

\item{collapse}{a single string or \code{NULL}; an optional
results separator}
}
\value{
Returns a character vector.
}
\description{
These functions concatenate all the strings in each character vector
in a given list.
\code{stri_c_list} and \code{stri_paste_list} are aliases for
\code{stri_join_list}.
}
\details{
Unless \code{collapse} is \code{NULL}, the result will be a single string.
Otherwise, you get a character vector of length equal
to the length of \code{x}.

Vectors in \code{x} of length 0 are silently ignored.

If \code{collapse} or \code{sep} has length greater than 1,
then only the first string will be used.

stri_join_list(

stri_join_list(

   'Spam spam bacon sausage and spam.')),

   stri_extract_all_regex(
      c('spam spam bacon', '123 456', 'spam 789 sausage'), '\\\\p{L}+'
   ),
sep=',')
