Fix regression introduced while implementing nano-like page up/down in
commit b2dbcb3e: if the view is already at the end of the buffer and
the last line is even above the bottom, i.e. there are some empty
lines displayed below the last line (e.g. if we have scrolled past the
last line via the mouse wheel), pressing PageDown not just moves the
cursor to the last line but also unexpectedly adjusts the view so that
the last line is exactly at the bottom.
Fix regression introduced in commit fdacb28962 ("CopyLine, CutLine,
DeleteLine: respect selection"): when CopyLine, CutLine or DeleteLine is
done in the last line of the buffer and this line is not empty, this
line gets selected but does not get copied/cut/deleted (and worse, it
remains selected).
Print release version tag in tools/build-version.go even if the commit
being checked has a tag that is not a version number if there are no
commits ahead.
action/command: Allow `-vsplit` & `-hsplit` as optional argument for `help`
Additionally the help, vsplit and hsplit command can now open multiple files like the tab command.
Commit 9fdea82542 ("Fix various issues with
`SpawnMultiCursor{Up,Down}`") changed SpawnMultiCursorUp/Down actions to
honor softwrap, i.e. spawn cursor in the next visual line within a
wrapped line, which may not be the next logical line in a buffer. That
was done for "consistency" with cursor movement actions CursorUp/Down
etc. But it seems there are no actual use cases for that, whereas at
least some users prefer spawning multicursor in the next logical line
regardless of the softwrap setting. So restore the old behavior.
Fixes#3499
In cursor's Goto(), which is currently only used by undo and redo, we
restore remembered LastVisualX and LastWrappedVisualX values. But if
the window had been resized in the meantime, the LastWrappedVisualX
may not be valid anymore. So it may cause the cursor moving to
unexpected locations.
So for simplicity just reset these values on undo or redo, instead of
using remembered ones.
Restore the original meaning of LastVisualX before commit 6d13710d93
("Implement moving cursor up/down within a wrapped line"): last visual x
location of the cursor in a logical line in the buffer, not in a visual
line on the screen (in other words, taking tabs and wide characters into
account, but not taking softwrap into account). And add a separate
LastWrappedVisualX field, similar to LastVisualX but taking softwrap
into account as well.
This allows tracking last x position at the same time for both cases
when we care about softwrap and when we don't care about it. This can be
useful, for example, for implementing cursor up/down movement actions
that always move by logical lines, not by visual lines, even if softwrap
is enabled (in addition to our default CursorUp and CursorDown actions
that move by visual lines).
Also this fixes a minor bug: in InsertTab(), when `tabstospaces` is
enabled and we insert a tab, the amount of inserted spaces depends on
the visual line wrapping (i.e. on the window width), which is probably
not a good idea.
Since we already have the StoreVisualX() helper, use it all over the
place instead of setting LastVisualX directly.
This will allow us to add more logic to StoreVisualX() add let this
extra logic apply everywhere automatically.
When saving a file with sudo fails (e.g. if we set `sucmd` to a
non-existent binary, e.g. `set sucmd aaa`), we erroneously return
success instead of the error, as a result we report to the user that
that the file has been successfully saved. Fix it.
When we are saving a file with sudo, if we interrupt sudo via Ctrl-c,
it doesn't just kill sudo, it kills micro itself.
The cause is the same as in the issue #2612 for RunInteractiveShell()
which was fixed by #3357. So fix it the same way as in #3357.
