Using iTerm's Semantic History with viMay 15 2015
If you’re running the nightly version of iTerm (which, if you like surprises, I suggest you do) you might have noticed a new feature called Semantic History.
In short, Semantic History allows you to ⌘-click on a filename (in your terminal) and perform an action on that file (or rather, with that filename).
Obviously, the ideal action is to open that file in that terminal window, in
your editor, but if you use
vi, the default option might not be enough for
you… mainly because
vi is probably not listed as an option.
You can find the “Semantic History” feature under Preferences -> Profiles -> Advanced.
You might think that the “Run command” option is what you want, but you’d be wrong! This simply runs a new process, separate from your existing session.
What you actually want is the “Run coprocess” command. This will run the given command in the same session that the filename was clicked in.
Because iTerm is helpful, in addition to filenames, it can also recognize line
vi will jump you to the end of the file if no line number
is specified (if it’s just a regular filename).
Hence, the ideal coprocess to run is as follows:
[ -z "\2" ] && echo vi \1 || echo vi +\2 \1
This checks if the
\2 param is zero-length or not. If it is, it just calls
vi on the filename. If not, it calls
+\2 which makes
vi jump to
the line number.
