Make anchor processing a bit more obvious 2020-09-28 22:18:17 +02:00

Improve PAGER defaults 
We basically need less(1), nothing else will work correctly.

I'm not sure where I took pager(1) from, might be a Debian thing.

Show error output from failed helpers 
Usually, when the pager or the editor fail and return a non-zero
exit status, they display a message on the standard error output.

We might also try to redirect this output to show_mesage() but
it might not fit as a whole, so, given the relative rareness
of this situation, this slight inconsistency shouldn't be much
of an issue.

It'd also be possible to redirect the output to run_pager() but
in doing so, we might make the problem recursive.

Fix tilde expansion algorithm 
In principle correct, in practice completely broken.

I wrongly assumed basic_string::find() would behave like strcspn(),
and also used a nonsensical string index to check for the tilde.

Support tilde expansion in the "chdir" action 
The tilde may be escaped, and this first escape may be escaped
as well, so all paths should be expressable.

All will just work(TM) for those who need it, and those who start
filenames with backslashes are begging to have their foot shot.

It appears that even Shift JIS, Big5, GB 18030, and GBK are
compatible with Unix paths, meaning they don't redefine the slash
(0x2F), so I'm okay with my direct multibyte string handling in
unknown locales.

Legacy stuff smells.

Make F3 change directories 
Best complemented with a less(1) configuration that also quits on F3,
just like mcview.  Or invoke sdn with PAGER=mcview, even though you
lose the ability to view the help that way (but gain filters).

Fixes for previous commits 
".." used to be hidden together with hidden files,
and the symlink patch introduced a compiler warning.
