+## cgit-gopher
+
+The plan is to equip cgit with a Gopher (RFC 1436) front-end. This would
+be possible by replacing the functions in ui-*.c with appropriate
+functions to generate Gopher contents. In practice, all the html-related
+stuff should be replaced by simple text, and the output simplified (we
+can't have more than one link per line in Gopher).
+
+It seems that ui-tree.c is a good place to start for a proof-of-concept.
+
+(20180724-16:19)
+
+ The PoC works. Now we should produce proper selectors for the stuff in
+ the tree page. In particular:
+
+ - Distinguish between files and directories/links
+ - construct an appropriate selector path (see cgit_tree_link in
+ ui-shared.c)
+
+ N.B.: We don't need to support all the stuff in cgit. In particular,
+ the 'virtual-root' variable might be a bit cumbersome to implement,
+ since we need an explicit way to signal the Gopher server that we
+ need the script (i.e., the presence of a '?' after the name of the CGI
+ script).
+
+(20180725 - 9:30)
+
+ The easiest way to inject a Gopher interface seems to be through
+ cmd.c, since the functions to be called for each action are defined in
+ there. It should be sufficient to provide a gopher-cmd.c and to
+ replace all the ui-*.c files with the corresponding ui70-*.c
+ counterparts which implement the Gopher interface.
+
+ Again, we should start from ui-repolist.c and ui-tree.c, which are the
+ two necessary bits for a viable proof-of-concept.
+
+(20180729 - 6:20)
+
+ The PoC is complete. The cgit-70 cgi script implements all the basic
+ functionalities of cgit. I am sure more is to be done, but the result
+ is not bad at all.

+ ---------------------------
+
+cgit-70 is a mod/fork of cgit (https://git.zx2c4.com/cgit/), the popular
+web-front-end to git. cgit-70 provides a dynamic interface to git
+repositories over Gopher. I started working on a proof-of-concept of a
+simple gopher interface to git, modifying a few functions in cgit, but
+after the first bits fell nicely into place, I decided to keep going and
+replace as much as possible of the web interface with corresponding
+gopher-friendly stuff. The result is cgit-70.
+
+You can see cgit-70 in action at:
+
+ gopher://cgit.mine.nu/1/cgit-70.cgi
+
+and you can clone the repo at:
+
+ http://cgit.mine.nu/cgit-70
+
+All you need to run cgit-70 is a gopher server that supports the same
+CGI interface defined by geomyidae (http://git.r-36.net/geomyidae/). If
+you like shell-stuff, you could also give a try to gosher
+(http://cgit.mine.nu/gosher), which implements the same interface.
