*Tilde.Club* has
|
|
[The Traditional Vi](https://ex-vi.sourceforge.net/)
|
|
installed on its premises.
|
|
It is not just another
|
|
[Vi clone](https://texteditors.org/cgi-bin/wiki.pl?ViFamily),
|
|
but the direct continuation
|
|
of Bill Joy's legendary work at Berkeley.
|
|
The binaries are in `/usr/archaic/bin/`
|
|
and the man pages
|
|
(separately for `ex` and `vi`)
|
|
in `/usr/archaic/share/man/man/`.
|
|
|
|
You can invoke *The Traditional Vi* in several ways
|
|
(in the order of increased engagement):
|
|
|
|
1. by the full path to the executable:
|
|
|
|
/usr/archaic/bin/vi
|
|
|
|
2. by adding it as an alias to your shell's `rc` file
|
|
(`~/.bashrc` for *Bash*), e.g:
|
|
|
|
alias tvi=/usr/archaic/bin/vi
|
|
|
|
and then invokng *Vi* by typing `tvi`,
|
|
|
|
3. by adding the locations *Vi* and its documentation
|
|
in front of the `PATH` and `MANPATH` environment variables
|
|
in your shell's profile script
|
|
(for *Bash*, `~/.bash_profile` or `~/.profile`):
|
|
|
|
export PATH="/usr/archaic/bin/:$PATH"
|
|
export MANPATH="/usr/archaic/share/man/man:$MANPATH"
|
|
|
|
The latter method has the advantage
|
|
of affecting subshells,
|
|
so that if you specify `vi` as the default editor
|
|
in your e-mail or news client, or another CLI program,
|
|
it will invoke *The Traditional Vi*,
|
|
ditto for your shell scripts
|
|
and the `EDITOR` environment variale.

## Building
|
|
|
|
*The Traditional Vi* is surprisingly easy to build from
|
|
[its source](https://sourceforge.net/p/ex-vi/code/).
|
|
You only need to locate the following line in `Makefile`:
|
|
|
|
TERMLIB = termlib
|
|
|
|
and replace the value with `curses` or `ncurses`,
|
|
depending on your preferred terminal library.
|
|
Now you can build and install the project with:
|
|
|
|
make && make install
|
