* Survive a removed CWD, as well as an empty rootPřemysl Eric Janouch2020-10-021-14/+22
| | | | | All the omitted error checking sometimes sucks a lot, and I need to include it later anyway.
* README.adoc: fix zsh integration snippetPřemysl Eric Janouch2020-10-021-0/+6
|
* Make the outer prompt look more normalPřemysl Eric Janouch2020-10-012-8/+10
| | | | | | | | There's a slight issue with the inverted cell representing the cursor standing out a bit too much amongst the rest of the characters. The resulting experience is a lot more consistent, though.
* Show external command line if appropriatePřemysl Eric Janouch2020-10-012-9/+27
| | | | | | | | | | | | | | Since I'm already dealing with the fish shell. All of our supported shells seem to handle cursor position in Unicode (wide character) codepoints. It was easiest and most straight-forward to pass the data through yet-unused program arguments. The cursor position is marked by a Unicode glyph equivalent to ACS_DIAMOND, although ncurses doesn't get a chance to make any ACS translation.
* README.adoc: clarify bash problemsPřemysl Eric Janouch2020-10-011-2/+3
| | | | | I've also tried tcsh but while it /can/ be used for directory navigation, it has several issues that are much more serious.
* README.adoc: fix up hswg compatibilityPřemysl Eric Janouch2020-10-011-6/+6
|
* README.adoc: split into subsectionsPřemysl Eric Janouch2020-10-011-14/+20
|
* README.adoc: add configuration for fishPřemysl Eric Janouch2020-10-011-1/+19
|
* Set cursor to child when going to parent dirPřemysl Eric Janouch2020-09-291-18/+26
| | | | | | | | | | | That is, if it's missing from our history. This makes for a more consistent experience when traversing the filesystem. Arguably, it's only good for when 'h' is bound to the 'parent' action. Also make sure that the offset and cursor are reset when the path is changed.
* CleanupPřemysl Eric Janouch2020-09-291-3/+2
|
* Add ability to run helpers externallyPřemysl Eric Janouch2020-09-292-13/+36
| | | | So far experimental and essentially undocumented.
* reload() doesn't really need to know the old pathPřemysl Eric Janouch2020-09-281-12/+13
| | | | | | | | | Just whether it's safe for it to keep an anchor on the current item. I've left in the safety check for an empty entries array, for the theoretical case of an empty or entirely filtered-out root directory. It will likely crash in that case, anyway, the cursor may be either -1 or 0.
* Make anchor processing a bit more obviousPřemysl Eric Janouch2020-09-281-2/+2
|
* Improve PAGER defaultsPřemysl Eric Janouch2020-09-281-2/+4
| | | | | | 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.
* README.adoc: talk about view and edit helpersPřemysl Eric Janouch2020-09-281-4/+18
|
* Expand a comment about overstriked underliningPřemysl Eric Janouch2020-09-281-1/+2
|
* Show error output from failed helpersPřemysl Eric Janouch2020-09-281-0/+6
| | | | | | | | | | | | | 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 algorithmPřemysl Eric Janouch2020-09-281-2/+2
| | | | | | | 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.
* Fix comment: the word "no-op" needs to be splitPřemysl Eric Janouch2020-09-281-1/+1
|
* Support tilde expansion in the "chdir" actionPřemysl Eric Janouch2020-09-281-5/+24
| | | | | | | | | | | | | | | 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 directoriesPřemysl Eric Janouch2020-09-271-1/+6
| | | | | | 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).
