ged

ged is ed rewritten in pure Go. Ged is the wizard of earthsea.

Using ged

To install ged, you need Go >= 1.12. Once you have that, just:

$ go get github.com/jlowellwofford/ged

This will install ged in $GOPATH/bin.

To build by hand, use (inside the folder where you have the ged source):

$ git clone https://github.com/jlowellwofford/ged
$ cd ged
$ go build . 

Once you have ged in your path, you should be able to run it and it should behave more-or-less like GNU Ed.

About ged

ged is intended to be a feature-complete mimick of GNU Ed. It is a close enough mimick that the GNU Ed Man Page should be a reliable source of documentation. Divergence from the man page is generally considered a bug (unless it's an added feature).

There are a few known differences:

• ged uses go's regexp package, and as such may have a somewhat different regular expression syntax. Note, however, that backreferences follow the ed syntax of \<ref>, not the go syntax of $<ref>.
• there has been little/no attempt to make particulars like error messages match GNU Ed.
• rather than being an error, the 'g' option for 's' simply overrides any specified count.
• does not support "traditional" mode

The following has been implemented:

• Full line address parsing (including RE and markings)
• Implmented commands: !, #, =, E, H, P, Q, W, a, c, d, e, f, h, i, j, k, l, m, n, p, q, r, s, t, u, w, x, y, z

The following has not yet been implemented, but will be eventually:

• Unimplemented commands: g, G, v, V
• does not (yet) support "loose" mode
• does not (yet) support "restricted" mode
