Major changes: do not delete and recreate markers and curves for every tempo map
change, attach tempo curves directly to their (preceding) tempo marker, notable
cleanup of TempoCurve class to remove unnecessary members.
More tweaks expected since algorithm for matching markers and tempo map
points is not correct yet.
Editor::drop_regions() creates a new RegionInsertDrag()
with the region to drop to the timeline.
RegionInsertDrag is-a RegionMotionDrag is-a RegionDrag is-a Drag.
However the region does not yet exist on the timeline and
RegionView is NULL.
This will likely need an API change. e.g.
Directly pass the TimeDomain as argument. The information can
be provided by the region, or from the TimeAxisView or RouteUI
when dropping a new source/region.
Important logic from 6.9 was either missing or incorrectly implemented. New
version is much simpler - we just use the RoundDownMaybe mode of round_to_bbt()
to ensure that the note start is always within the current grid even if the
mouse is more than halfway "through" it.
MSVC is happy to ignore the above pragma although it aborts the build if it encounters #warning
#pragma GCC warning seems to work fine here for Clang - so start by changing just 1 x file to see if there's any detrimental effect for the other builds.
This means that we actually explicitly reposition all regions as part of the drag, and do not need to call
Editor::do_ripple(). We do still need to call Editor::ripple_marks() though
*now that you can grab "anywhere" in the region, trim edges are inferior because they are hard to hit
*modifier had to change anyway (since CTRL is used as a copy-drag on both mac and win), so that invalidates prior muscle memory
*potentially frees up modifier on the trim edge for some other purpose (anchored_trim)
Control Points should ignore x_constraint which is set in Drag::motion and potentially other places.
The only thing that should prevent CP sliding is can_slide which is false for the points at the ends of a region.
Ripple edit undo/redo needs a "recursive diff" of all regions
in the playlist. To work properly owned changes have to be
cleared first, previously unrelated edits were be collected too.
This includes a more consistent version of
7a89d56009 using rdiff() instead of explicitly
saving region diffs.
Previously x-axis threshold was in samples. This is
useless unless zoomed in to the max. So in most cases
the first-move was always in x-direction, making constrained
y-axis drags near impossible.
Furthermore the threshold for copy-drags was increased
as per #8686
Region positions were updated in the GUI, before the playlist
was catching up.
The butler thread reads a region using the region's new position,
but the playlist's old range.
Thread 1 (GUI)
```
#22 ARDOUR::Playlist::notify_layering_changed()
#26 ARDOUR::AudioPlaylist::region_changed
#27 ARDOUR::Playlist::region_changed_proxy
#35 ARDOUR::Region::send_change
#36 ARDOUR::Region::set_position
#37 RegionRippleDrag::remove_unselected_from_views
#38 RegionRippleDrag::finished
```
LayeringChanged() also triggers DiskIOProcessor::playlist_modified
which schedules a pending-override and summons the butler.
Note that when moving only a few regions the butler starts after all
updates have been completed.
Butler thread:

Region read fails:
```
libs/ardour/audioregion.cc:503 assert (position >= _position);
(gdb) p position
$1 = 1312000
(gdb) p _position
$2 = {<PBD::PropertyTemplate<long>> = {_have_old = true,
_current = 1336000, _old = 1312000} }
```
The DraggingView's time_axis_view (index) is set to the size of _time_axis_views
in ::motion() near line 1149. This makes it invalid as index into the vector.
Playlist changes do not include region-property changes.
When inserting a region, position(s) of other Regions may
change and those changes have to be recorded explicitly (for now).
see also RegionRippleDrag.
This is in preparation to subscribe to playhead cursor position
changes in the recorder-UI.
This change also clean up the API, replacing a public variable
with a const access method and follows #12 of
https://ardour.org/styleguide.html
When ripple moving a region all the subsequent regions will be moved, next
region in the playlist after the dragged one first, last region of the playlist
last.
Thus, when an automation point is ripple moved along a region past the starting
point of the next region, it will be moved again along with the next region as
the move of the next region occurs after moving the automation point.
This fix reverses the sequence of the ripple moves, last region in the playlist
will be moved first, the next after the dragged one, last. So no temporary
overlap of regions will occur.
As soon as we ripple drag the selected region out of the original track,
::remove_unselected_from_views() is called and the rippled regions on the
original track are not covered when ::remove_selected_from_views() is called
again in ::finished(). Therefore we need to shift the regions remaining on the
original track back and forth again, in order to have them properly in the undo
history.
RegionMoveDrag::finished_no_copy() calls ::clear_changes() on every selected
Region and then sets their positions again before committing the command to the
UndoHistory. By doing that no changes from the previous transaction spill over
into the current transaction.
This needs to be done in a similar way by in RegionRippleDrag::finished()
because otherwise a following undo action would also undo the changes of the
previous transaction for all the non selected rippled regions.
RegionRippleDrags across tracks are still borked, though.
Previously adding percussive-hits created sustained notes
using the current grid as duration. This allowed to create
overlapping notes with the overlap not being visible.
Most hardware MIDI drumkits do send an immediate note-off event
after each hit (if they send note-offs at all).
Ardour now follows suit and does the same when using the draw/edit tool.
Copyright-holder and year information is extracted from git log.
git history begins in 2005. So (C) from 1998..2005 is lost. Also some
(C) assignment of commits where the committer didn't use --author.
This is work in progress towards fixing stacked region's region-gain
and multiple discontinuous regions spanning multiple tracks.
AutomationRangeDrag::setup() still does not collect all AutomationLine
points for certain overlap scenarios. There's more to come...
* Both the session-start and session-end point should follow the is-free option
* Rename the end-is-free option to session-range-is-free, to reflect that change
* This fixes the problem: recording before the start marker would move the Start,
even if the user had already fixed the End marker.
We no longer assume that Snap always uses the visible ruler lines.
If you want to snap to the grid, and ignore the users zoom scale, use SnapPref::SnapToGrid_Unscaled
This fixes 2 (known) oversights: "snap region(s) to grid" and "regions whose start are left of the canvas edge".
Separate Snap from Grid. Lots of naming changes.
Multiple simultaneous snap options allowed. Grid is one of the possible Snap options.
Grid uses the same data as the rulers. Replace complicated tempo_lines with simple grid_lines.
The Grid is zoom-scale-sensitive along with the rulers. If you are zoomed out, grid becomes coarser.
Snapped Cursor is a line that follows the edit point, and indicates where the operation will occur.
This replaces and extends the line that appears with the Cut tool.
New associated preferences: snap_threshold and show_snap_cursor.
Generated by tools/f2s. Some hand-editing will be required in a few places to fix up comments related to timecode
