Major Section: ACL2-BUILT-INS
Use princ$ to do basic printing of atoms (i.e., other than cons
pairs). In particular, princ$ prints a string without the surrounding
double-quotes and without escaping double-quote characters within the string.
Note that princ$ is sensitive to the print-base, print-radix, and
print-case; see set-print-base, see set-print-radix, and
see set-print-case. Princ$ returns state.
Examples:
ACL2 !>(princ$ "Howdy ho" (standard-co state) state)
Howdy ho<state>
ACL2 !>(pprogn (princ$ "Howdy ho" (standard-co state) state)
(newline (standard-co state) state))
Howdy ho
<state>
ACL2 !>(princ$ "ab\"cd" *standard-co* state)
ab"cd<state>
ACL2 !>
ACL2 !>(princ$ 17 *standard-co* state)
17<state>
ACL2 !>(set-print-base 16 state)
<state>
ACL2 !>(princ$ 17 *standard-co* state)
11<state>
ACL2 !>(set-print-radix t state)
<state>
ACL2 !>(princ$ 17 *standard-co* state)
#x11<state>
ACL2 !>(princ$ 'xyz *standard-co* state)
XYZ<state>
ACL2 !>(set-print-case :downcase state)
<state>
ACL2 !>(princ$ 'xyz *standard-co* state)
xyz<state>
ACL2 !>
See fmt for more sophisticated printing routines, and see IO for general information about input and output.
