Write to PORT the expressions and blanks listed in LST.

Like 'read', but include <blank> objects when they're encountered. When BLANK-LINE? is true, assume PORT is at the beginning of a new line.

Read from PORT until the end-of-file is reached and return the list of expressions and blanks that were read.

Pretty-print OBJ with INDENT columns as the initial indent. ARGS are passed as-is to 'pretty-print-with-comments'.

Write OBJECT (typically a record) as a series of recutils-style fields to PORT, according to FIELDS. FIELDS must be a list of field name/getter pairs.

Apply MAKE to the values associated with KEYS in ALIST. Items in KEYS that are also in MULTIPLE-VALUE-KEYS are considered to occur possibly multiple times in ALIST, and thus their value is a list.

Read a recutils-style record from PORT and return it as a list of key/value pairs. Stop upon an empty line (after consuming it) or EOF.

Evaluate EXP, a gexp, on the host at SESSION, an SSH session. Ensure that all the elements EXP refers to are built and deployed to SESSION beforehand. When BUILD-LOCALLY? is true, said dependencies are built locally and sent to the remote store afterwards; otherwise, dependencies are built directly on the remote store.

Run a machine-usable REPL over ports INPUT and OUTPUT.

The protocol of this REPL is meant to be machine-readable and provides proper support to represent multiple-value returns, exceptions, objects that lack a read syntax, and so on. As such it is more convenient and robust than parsing Guile's REPL prompt.

Write the response corresponding to the evaluation of EXP to PORT, an output port. VERSION is the client's protocol version we are targeting.

Generate a RPM lead u8-list that uses NAME-VERSION, the name and version string of the package, and TARGET, a GNU triplet used to derive the target machine type.
