Ed-0.8

[dnicholson@…]

Apparently ed is alive. There have been three releases since the fall. Ed-0.5 released in March.

Wow. An update after only 12.5 years! Sun Jun 26 22:21:59 1994 -> 2006-11-11

This is now a simple CMMI app. No patch required. Compiles cleanly. Time is "less than 0.1 SBU." Disk space is 1.3Mb. Download size is 53Kb.

./configure --prefix=/usr
make
make check
sudo make install
sudo make install-man

Installs four files: ed, red, ed.1, and ed.info. Note that red is a hard link to ed, not a separate file. The info file is installed automatically. The man file must be installed separately.

Hmm, we may not want to jump at this so fast. I think there might be some issues with backwards compatibility, which is pretty much the only reason to even have ed. Read this thread on bug-ed. It's not too inspiring.

Interesting read, I like this statement. "ed is a program I do not use, a program I do not like, and a program I am voluntarily maintaining to help the GNU project just because nobody else wants to maintain it"

Anyway, the following test is working in ed 0.5

cat > test <<EOF
That was a bug in 0.4
http://lists.gnu.org/archive/html/bug-ed/2007-02/msg00000.html
EOF
ed test <<EOF
%s/a bug in 0.4/fixed in 0.5
%s/2007-02\/msg00000/2007-03\/msg00012
w
q
EOF
cat test
That was fixed in 0.5

Indeed there are problems with this version. Reading the ed message list, ed-0.5 hangs with 100% cpu usage with:

ed < /dev/null

instead of simply terminating or giving some type of error message.

Moving to future. Don't implement until the above problem is fixed.

[Ag. Hatzimanikas]

Version increment to 0.8. Searching through the archives, I can't see any bug report, so moving this from future to 6.3.

[Ag. Hatzimanikas]

Fixed in r7126.

Alexander, I removed the warning. If still there is a problem, please report it and I will revert the change.

Thanks Bruce.
