History

imp 0ed032933f When building picobsd, define WITHOUT_OPENSSL and WITHOUT_KERBEROS and remove the now-redundant checks for RELEASE_CRUNCH. This originally was defined for building smaller sysinstall images, but was later also used by picobsd builds for a similar purpose. Now that we've moved away from sysinstall, picobsd is the only remaining consumer of this interface. Adding these two options reduces the RELEASE_CRUNCH special cases in the tree by half.		2014-06-06 04:09:07 +00:00

README

$FreeBSD$

ed is an 8-bit-clean, POSIX-compliant line editor.  It should work with
any regular expression package that conforms to the POSIX interface
standard, such as GNU regex(3).

If reliable signals are supported (e.g., POSIX sigaction(2)), it should
compile with little trouble.  Otherwise, the macros SPL1() and SPL0()
should be redefined to disable interrupts.

The following compiler directives are recognized:
DES		- to add encryption support (requires crypt(3))
NO_REALLOC_NULL	- if realloc(3) does not accept a NULL pointer
BACKWARDS	- for backwards compatibility
NEED_INSQUE	- if insque(3) is missing

The file `POSIX' describes extensions to and deviations from the POSIX
standard.

The ./test directory contains regression tests for ed. The README
file in that directory explains how to run these.

For a description of the ed algorithm, see Kernighan and Plauger's book
"Software Tools in Pascal," Addison-Wesley, 1981.
