This sounds like a description of Guile's REPL itself.  Are you looking
to implement your own simple REPL for educational purposes?

Yes and yes.

Here are some relevant sections of the Guile manual to get started:

  https://www.gnu.org/software/guile/manual/html_node/Scripting-Examples.html
  
https://www.gnu.org/software/guile/manual/html_node/Read_002fLoad_002fEval_002fCompile.html
  https://www.gnu.org/software/guile/manual/html_node/Line_002fDelimited.html
  https://www.gnu.org/software/guile/manual/html_node/Strings.html

The first link gives several small examples of Guile scripts.  The
second documents procedures to read, evaluate, and print S-expressions,
and in particular the 'read', 'eval', and 'write' procedures, which are
the three main components of a REPL.  The third link documents
procedures to read a single line of input as a string, and the fourth
documents the string operations.

Would you like to start by looking over these sections of the manual,
and then asking more questions as they arise?
