Swaping `MainTab` calls to `h.tab` will not change the normal micro
behaviour.
This changes will make possible to call `ForceQuit`, `VSplitIndex` and
`HSplitIndex` for tabs that aren't main one.
When adding a new `BufPane` it is always being inserted last into `MainTab().Panes`.
This leads to a confusion when using the actions `PreviousSplit`, `NextSplit` as the previous/next split may not be the expected one.
How to reproduce:
- Launch micro and insert char "1"
- Open a new vsplit via the command `vsplit` and insert "2"
- Switch back to the left split (1) by using `PreviousSplit`
- Again open a new vsplit via command: `vsplit` and type char "3"
- Now switch between the 3 splits using `PreviousSplit`, `NextSplit`
Switching from most left split to the most right, the expected order would be 1, 3, 2 but actually is 1, 2, 3.
Also tweaked the behavior of Paragraph/{Previous/Next} so that it skips
all empty lines immediately next to cursor position, until it finds the
start/end of the paragraph closest to it. Once it finds the paragraph
closest to it, the same behavior as before applies. With the previous
behavior if the cursor was surrounded by empty lines, then
Paragraph/{Previous/Next} would only jump to the next empty line,
instead of jumping to the start/end of a paragraph.
Instead of calling execAction() and then letting it check whether it
should actually execute this action, do this check before calling
execAction(), to make the code clear and straightforward.
Precisely: for multicursor actions, call execAction() in a loop for
every cursor, but for non-multicursor actions, call execAction() just
once, without a loop. This, in particular, allows to get rid of the
hacky "c == nil" check, since we no longer iterate a slice that may
change in the meantime (since SpawnMultiCursor and RemoveMultiCursor
are non-multicursor actions and thus are no longer executed while
iterating the slice).
- SpawnMultiCursor and RemoveMultiCursor actions change the set of
cursors, so we cannot assume that it stays the same. So refresh the
`cursors` list after executing every action in the chain.
- If execAction() did not execute an action since it is not a
multicursor, it should return true, not false, to not prevent
executing next actions in the chain.
The lastCutTime feature (reset the clipboard instead of appending to the
clipboard if the last CutLine was more than 10 seconds ago) was
implemented 8 years ago but was always buggy and never really worked,
until we have accidentally found and fixed the bug just now. No one ever
complained or noticed that, which means it is not a very useful feature.
Fixing it changes the existing behavior (essentially adds a new feature
which did not really exist before) and there is no reason to assume that
this new behavior will be welcome by users. So it's better to remove
this feature.
According to tcell documentation, Rune() should only be used for KeyRune
events. Otherwise its return value is not guaranteed and should not be
relied upon.
This fixes issue #2947: Esc key not working on Windows, since tcell
sends lone Esc key event with rune == 0 on Unix but with rune == 27
(the keycode) on Windows.
- Add a new Duplicate action which just duplicates the selection (and
returns false if there is no selection).
- Change the behavior of the DuplicateLine action to only duplicate the
current line, not the selection.
- Change the default action bound to Ctrl-d from DuplicateLine to
Duplicate|DuplicateLine, so that the default behavior doesn't change.
This allows the user to rebind keybindings in a more flexible way, i.e.
to choose whether a key should duplicate just lines, or just selections,
or both, - in a similar fashion to Copy, Cut, Delete actions.
Weird behavior is observed e.g. if we cut some lines with CutLine, then
copy some selection with Copy, then cut some other lines with CutLine,
and then paste. The pasted cliboard contains not just the lines that
were cut at the last step, but also the selection that was copied before
that.
Fix that by resetting the CutLine's repeated line cuts whenever we
copy anything to the clipboard via any other action (Cut, Copy or
CopyLine).
If onBufPaneOpen callback execution fails (e.g. due to a Lua runtime
error), report this error to the user, like we do for all other Lua
callbacks, rather than silently continue working as if nothing
happened.
After reloading a file that has been externally modified, the buffer
view may become invalid: the displayed subset of lines of the file may
no longer exist, since the file may have been truncated. So relocate the
buffer view in this case.
In particular, this fixes crashes caused by out of bounds accesses to
the line array by displayBuffer() trying to display no longer existing
lines.
Currently onSetActive is called when the user clicks with the mouse on
a pane even if this pane is already active. We should avoid calling it
in this case.
Implementation detail: like with tabs in the previous commit, we cannot
check if the pane is already active just by checking the index passed
to the Tab's SetActive() (since the index may not change while the pane
itself changes), we need to check state of the pane itself. So we move
the onSetActive invocation from the Tab's SetActive() to the BufPane's
SetActive().
- If a mouse event is bound to a Lua function, pass *tcell.EventMouse to
this Lua function, so that it can find out the position where a button
was clicked etc, just like the built-in MousePress and MouseMultiCursor
actions.
- Make mouse actions more a first-class citizen: allow chaining them and
running onAction and preAction callbacks for them, just like key actions.
Improve user experience: if we are at a line with a new (i.e.
not highlighted yet) trailingws and we begin selecting text,
don't highlight the trailingws until we are done with selection,
even if we moved the cursor to another line while selecting.
Added option `hltrailingws` for highlighting trailing whitespaces
at the end of lines. Note that it behaves in a "smart" way.
It doesn't highlight newly added (transient) trailing whitespaces
that naturally occur while typing text. It would be annoying to
see transient highlighting every time we enter a space at the end
of a line while typing.
So a newly added trailing whitespace starts being highlighting
only after the cursor moves to another line. Thus the highlighting
serves its purpose: it draws our attention to annoying sloppy
forgotten trailing whitespaces.
* Add reload setting
Can be set to:
* auto - Automatically reload files that changed
* disabled - Do not reload files
* prompt - Prompt the user about reloading the file.
* option: Add default value for reload option and documentation

* Comment fix & gofmt fix
* Goto next/previous diff commands
These commands will work in `git` repositories or whenever `set diff on` is
working. They are bound to `Alt-[` and `Alt-]` by default. I would prefer
`Alt-Up` and `Alt-Down`, but that's already taken.
There are no tests at the moment; I'm looking into writing some since that will
be needed for the rest of the plan to make
https://github.com/zyedidia/micro/discussions/2753 a reality. I'm not sure how
difficult that will be.
* Realign JSON in keybindings.md
When we temporarily disable the screen (e.g. during TermMessage or
RunInteractiveShell), if the mouse is pressed when the screen is still
active and then released when the screen is already stopped, we aren't
able to catch this mouse release event, so we erroneously think that the
mouse is still pressed after the screen is restarted. This results in
wrong behavior due to a mouse press event treated as a mouse move event,
e.g. upon the left button click we see an unexpected text selection.
So need to reset the mouse release state to "released" after restarting
the screen, assuming it is always released when the screen is restarted.
If we press mouse, drag and then release, the release event is
generated twice, since both mouse press and mouse drag events have been
saved in mousePressed map. To fix that, ensure that we only store mouse
press events in it.
Introduce separate mouse release and mouse drag (move while pressed)
events: MouseLeftRelease, MouseLeftDrag, MouseRightRelease etc,
to allow binding them to actions independently from mouse press events
(MouseLeft, MouseRight etc).
This change:
- Makes it possible to handle mouse release and drag for arbitrary mouse
events and actions (including Lua actions), not just for MouseLeft as
in the current code.
- Fixes issue #2599 with PastePrimary and MouseMultiCursor actions:
selection is pasted not only when pressing MouseMiddle but also when
moving mouse with MouseMiddle pressed; similarly, a new multicursor is
added not only when pressing Ctrl-MouseLeft but also when moving mouse
with Ctrl-MouseLeft pressed.
My initial approach was not to introduce new events for mouse release
and mouse drag but to pass "mouse released" info to action functions
in addition to *tcell.EventMouse to let the action functions do the
necessary checks (similarly to what MousePress is already doing). But
then I realized it was a bad idea, since we still want to be able also
to bind mouse events to regular key actions (such as PastePrimary)
which don't care about mouse event info.
* Improve buffer view relocation after jumping to a far-away location
When the cursor is moved to a location which is far away from the
current location (e.g. after a search or a goto line), the buffer view
is always relocated in such a way that the cursor is at the bottom or
at the top (minus scrollmargin), i.e. as if we just scrolled to this
location. It's not like in other editors, and IMHO it's annoying. When
we jump to a new location far away, we usually want to see more of its
context, so the cursor should be placed closer to the center of the
view, not near its edges.
This change implements the behavior similar to other editors:
- If the distance between the new and the old location is less than one
frame (i.e. the view either doesn't change or just slightly "shifts")
then the current behavior remains unchanged.
- Otherwise the current line is placed at 25% of the window height.
* Postpone calling onBufPaneOpen until the initial resize
It is currently not possible to find out the geometry of a newly created
bufpane in onBufPaneOpen lua callback: bp:GetView() returns {0,0,0,0}
instead of the actual window. The reason is that the bufpane view is not
properly initialized yet when the bufpane is created and the callback is
triggered. It is initialized a bit later, at the initial resize.
So postpone calling onBufPaneOpen until after the initial resize.
* Improve buffer view relocation when opening a file at a far-away location
When a file is opened with the initial cursor location at a given line
which is far away from the beginning of the file, the buffer view is
relocated so that the cursor is at the bottom (minus scrollmargin)
as if we just scrolled to this line, which is annoying since we'd rather
like to see more of the context of this initial location.
So implement the behavior similar to the earlier commit (which addresses
a similar issue about jumping far away after a search or goto):
- If the initial cursor location is less than one frame away from the
beginning of the buffer, keep the existing behavior i.e. just display
the beginning of the buffer.
- Otherwise place the cursor location at 25% of the window height.
* Support for highlighting all search matches (hlsearch)
hlsearch is implemented efficiently using the buffer's line array,
somewhat similarly to the syntax highlighting.
Unlike the syntax highlighter which highlights the entire file,
hlsearch searches for matches for the displayed lines only.
Matches are searched when the given line is displayed first time
or after it was modified. Otherwise the previously found matches
are used.
* Add UnhighlightSearch action
and add it to the list of actions triggered by Esc key by default.
* Add comment explaining the purpose of search map
* Add hlsearch colors to colorschemes
Mostly just copied from the corresponding original (mostly vim) colorschemes.
* Highlight matches during/after replace as well
As a side effect it also changes the last search value, i.e. affects FindNext
and FindPrevious, but it's probably fine. In vim it works the same way.
* Improve hlsearch option description
