# Bidirectional links with eev
Eduardo Ochs

Consider the two sexps below:
(code-c-d "foobar" "/tmp/foo/bar/" :anchor)
(code-c-d "fb" "/tmp/foo/bar/" :anchor)
Each one of them defines several "short hyperlink" functions. After
running them the three sexps below are roughly equivalent:
(find-file "/tmp/foo/bar/plic.txt")
(find-foobarfile "plic.txt")
(find-fbfile "plic.txt")
The "`code-c-d`"s above also define functions with even shorter names
– `find-foobar` and `find-fb` - that point to "anchors" in files in
the directory `/tmp/foo/bar/`. The three sexps below are roughly
equivalent -
(find-fline "/tmp/foo/bar/plic.txt" "«bletch»")
(find-foobar "plic.txt" "bletch")
(find-fb "plic.txt" "bletch")
Until feb/2022 the only way that I had to produce these hyperlinks to
anchors quickly required a LOT of muscle memory… I had to type this,
M-1 M-h M-w M-h M-h 9*<down> M-h M-2 M-h M-y M-h M-- M-h M-w M-k
where the number of "`<down>`"s depended on whether I preferred
`find-foobar` of `find-fb` - i.e., of on what is my preferred "code"
for the "directory" `/tmp/foo/bar/`; either "`foobar`" or "`fb`".
In this presentation I will show a much better way to generate short
hyperlinks to anchors and push these short hyperlinks to the kill
ring, and how I use that to create bidirectional hyperlinks between my
notes on a language $LANGUAGE and programs written in that language.
