gophed: burrowing the gopherspace with ed =============================================== `gophed` is a simple gopher client in a POSIX shell script. `gophed` uses ed(1) as a pager and navigator, and is based on an original idea of an ed-based client by Solene Rapenne (gopher://bitreich.org/1/usr/solene/). `gophed` is distributed under the ISC License. A copy of the LICENSE is available in the repo. The first time you run `gophed` you need to initialise it via: ./gophed -i This will create a few symlinks in the current folder, namely `g`, `v`, and `d`, which will be used as `gophed` commands. Once `gophed` has been initialised, you can start visiting some gopherholes: ./gophed / kalos.mine.nu 70 or equivalently: ./v / kalos.mine.nu 70 This command will download the corresponding resource, and print it on output with line numbers. An excerpt is reported below: ... 15 i+------------------------------------------+ Err kalos.mine.nu 70 16 i Welcome to kalos.mine.nu Gopher-hole Err kalos.mine.nu 70 17 i+------------------------------------------+ Err kalos.mine.nu 70 18 0 About me /me.txt kalos.mine.nu 70 19 0 About this gopherhole /about.txt kalos.mine.nu 70 20 1 Contacts /contacts kalos.mine.nu 70 21 i Err kalos.mine.nu 70 22 1 My gopherhole @SDF /users/katolaz sdf.org 70 23 1 My gopherhole @republic.circumlunar.space /~katolaz/ republic.circumlunar.space 70 24 1 My Phlog @republic.circumlunar.space /~katolaz/phlog republic.circumlunar.space 70 25 i+------------------------------------------+ Err kalos.mine.nu 70 26 i Projects Err kalos.mine.nu 70 27 i+------------------------------------------+ Err kalos.mine.nu 70 28 1 Burrow the Burrows (crawling the Gopherspace) /burrow/index.gph kalos.mine.nu 70 29 1 gosher -- a Gopher server in a shell script /software/gosher kalos.mine.nu 70 ... = The final "=" is the `gophed` default prompt. No need to say that you can change the default prompt to any single character by changing the PROMPT variable. Now, if you want to visit the selector at line 23, you would type: !./g % 24 [ENTER] at the prompt. This will effectively spawn another `gophed` instance, telling it to get the selector at line 23 in the current document, and to load the corresponding resource. In this case we will have something like: 1 i ________ ____ Err republic.circumlunar.space 70 2 i /_ __/ /_ ___ / __ \_ ______ _______ _____ ____ Err republic.circumlunar.space 70 3 i / / / __ \/ _ \ / / / / | /| / / __ `/ ___/ | / / _ \/ __ \ Err republic.circumlunar.space 70 4 i / / / / / / __/ / /_/ /| |/ |/ / /_/ / / | |/ / __/ / / / Err republic.circumlunar.space 70 5 i /_/ /_/ /_/\___/ /_____/ |__/|__/\__,_/_/ |___/\___/_/ /_/ Err republic.circumlunar.space 70 6 i Err republic.circumlunar.space 70 7 i ____ __ __ _ __ __ Err republic.circumlunar.space 70 8 i / __ )/ /___ ______/ /___________ ___ (_) /_/ /_ Err republic.circumlunar.space 70 9 i / __ / / __ `/ ___/ //_/ ___/ __ `__ \/ / __/ __ \ Err republic.circumlunar.space 70 10 i / /_/ / / /_/ / /__/ ,< (__ ) / / / / / / /_/ / / / Err republic.circumlunar.space 70 11 i /_____/_/\__,_/\___/_/|_/____/_/ /_/ /_/_/\__/_/ /_/ Err republic.circumlunar.space 70 12 i Err republic.circumlunar.space 70 13 i+------------------------------------------------------------------+ Err republic.circumlunar.space 70 14 i "their swords were forged by dwarves, in the mists of time..."

Typing q [ENTER] again will bring you back in history again. If you give a `q` command on the first page, you will leave `gophed`. If you would instead like to save the resource pointed by a selector, you will use the command: !./d % NUMBER [ENTER] where NUMBER is the number of the line where the selector appears in the current page. The resource will be saved at "HOSTNAME/URI" where HOSTNAME is the name of the host and URI is the path to the resource. If you don't remember which line is which, you can just give: %n [ENTER] at the prompt. If you don't remember which resource you are currently visiting, typing: f [ENTER] at the `gophed` prompt will give some hints. If you are an ed(1) user, you will totally understand what we are up to here, and probably will now have a good laugh. If you don't know how to use ed(1), instead, then this is probably the right time to start learning it. Remember: ed(1) is the standard editor, and an awesome one at that... HND KatolaZ
