After reading the documentation, reviewing the forum and seeing the comments, I have tried to move a code that I have using scantokens to tl_rescan:.

I want to save the result in a variable and then execute them, with scantokens works OK, but I use several times :D which is not recommended.

With tl_rescan: I do not achieve the expected result and I can not configure newlinechar (which only appears twice in the documentation), I have searched for examples but I have not found any to be able to adapt.

This is my sample file:

documentclass{article}

usepackage{filecontentsdef}

usepackage[enable-debug]{expl3}

usepackage{xparse}

ExplSyntaxOn

debug_on:n{check-declarations,deprecation,check-expressions}

% myscantokens

NewDocumentCommand{myscantokens}{+m}

 {

  group_begin:

  tl_set:Nn l_tmpa_tl {#1}

  tl_put_right:Nx l_tmpb_tl % 

    { 

     tex_newlinechar:D = 13

     tex_everyeof:D = { exp_not:N }

     exp_not:N scantokens exp_after:wN { l_tmpa_tl }

     tex_newlinechar:D = 10 scan_stop:

    }

  l_tmpb_tl

  group_end:

 }



% mytlrescan

tl_new:N l_tmpc_tl

cs_generate_variant:Nn tl_set_rescan:Nnn { NnV }

NewDocumentCommand{mytlrescan}{+m}

 {

  group_begin:

  tl_set:Nn l_tmpa_tl {#1}

  tl_set_rescan:NnV l_tmpb_tl { } l_tmpa_tl

  tl_put_right:Nx l_tmpc_tl %

    {

     tex_newlinechar:D = 13

     tex_everyeof:D = { exp_not:N }

     l_tmpb_tl

     tex_newlinechar:D = 10 scan_stop:

    }

    l_tmpc_tl

  group_end:

 }

ExplSyntaxOff

pagestyle{empty} % only for example

begin{document}

section{Default texttt{textbackslash filecontentsexec}}



begin{filecontentsdef*}{jobname.tmp}{macroA}

Test environment with verb+filecontentsdef*+. verb+macroA+ its global.par

section{Using texttt{textbackslash scantokens}}

myscantokens{macroA}



section{Using texttt{textbackslash tl_rescan:nn}}

And so it looks:

How do I configure {setup} in tl_rescan: to get the expected result?
