Simple question: How do you read a line from terminal to a token list variable in expl3?



The following is what I tried:



documentclassarticle
usepackageexpl3

begindocument
ExplSyntaxOn

read c_term_ior to l_tmpa_tl
tl_show:N l_tmpa_tl

ior_get:NN c_term_ior l_tmpa_tl
tl_show:N l_tmpa_tl

ExplSyntaxOff
enddocument


resulting in the expected behavior for the read version, but in q_no_value for the ior_get:NN version.

          You are looking for ior_get_term:nN (or perhaps ior_str_get_term:nN), added as candidates in March 2019. You'd do something like



          documentclassarticle
          usepackageexpl3

          begindocument
          ExplSyntaxOn
          ior_get_term:nN Foo ~ bar l_tmpa_tl
          tl_show:N l_tmpa_tl

          ExplSyntaxOff
          enddocument


          Due to an internal change of how input streams are managed, to make the check whether they are open more robust, the effect is that ior_get:NN no longer works with c_term_ior and for this reason ior_get_term:Nn has been introduced. Unfortunately, the documentation wasn't updated to reflect this.
