Since we now expose our own micro.After() API which is more convenient
and safer to use than directly using Go timers, we can remove exposing
Go timers to lua directly.
If we add something like this to init.lua:
config.AddRuntimeFile("status", config.RTHelp, "help/foo.md")
then start micro and run "help foo", the resulting error message looks
weird:
Unable to load help textfooopen plugins/status/help/foo.md: file does not exist
Change it to:
Unable to load help text for foo: open plugins/status/help/foo.md: file does not exist
- 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.
Handle the case when the cursor itself hasn't really moved to
another line, but its line number has changed due to insert
or remove of some lines above.
In this case, if the cursor is still at its new trailingws,
we should not reset NewTrailingWsY to -1 but update it to the
new line number.
A scenario exemplifying this issue:
Bind some key, e.g. Alt-r, to such a lua function:
function insertNewlineAbove(bp)
bp.Buf:Insert(buffer.Loc(0, bp.Cursor.Y), "\n")
end
Then in a file containing these lines:
aaa
bbb
ccc
insert a space at the end of bbb line, and then press Alt-r.
bbb and ccc are moved one line down, but also the trailing space
after bbb becomes highlighted, which isn't what we expect.
This commit fixes that.
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.
Added option `hltaberrors` which helps to spot sloppy whitespace errors
with tabs used instead of spaces or vice versa.
It uses the value of `tabstospaces` option as a criterion whether a
tab or space character is an error or not.
If `tabstospaces` is on, we probably expect that the file should contain
no tab characters, so any tab character is highlighted as an error.
If `tabstospaces` is off, we probably expect that the file uses
indentation with tabs, so space characters in the initial indent part
of lines are highlighted as errors.
* Fix gutter overwriting other split pane
When we resize a split pane to a very small width, so that the gutter
does not fit in the pane, it overwrites the sibling split pane.
To fix it, clean up the calculation of gutter width, buffer width and
scrollbar width, so that they add up exactly to the window width, and
ensure that we don't draw the gutter beyond this calculated gutter
width (gutterOffset).
As a bonus, this also fixes the crash #3052 (observed when resizing a
split pane to a very small width, if wordwrap is enabled), by ensuring
that bufWidth is never negative.
[*] By the gutter we mean of course gutter + diffgutter + ruler.
* Don't display line numbers if buffer width is 0 and softwrap is on
If softwrap is enabled, the line numbers displayed in the ruler depend
on the heights of the displayed softwrapped lines, which depend on the
width of the displayed buffer. If this width is 0 (e.g. after resizing
buffer pane to a very small width), there is no displayed text at all,
so line numbers don't make sense. So don't display line numbers in this
case.
* Fix buffer text overwriting scrollbar when window width is 1 char
Fix the following funny issue: if we open 3 vertical split panes (i.e.
with 2 vertical dividers between them) and drag the rightmost divider
to the left (for resizing the middle and the rightmost split panes), it
does not stop at the leftmost divider but jumps over it and then hovers
over the leftmost split pane. And likewise with horizontal split panes.
* Update docs to include `matchbracestyle`
* Add `matchbracestyle` to infocomplete.go
* Add validator and default settings for `matchbracestyle`
* Highlight or underline braces based on `matchbracestyle`
* Add `match-brace` to default colorschemes
* Correct `FindMatchingBrace()` counting
Make brace under the cursor have priority over brace to the left in
ambiguous cases when matching braces

* SpawnMultiCursorUp/Down: change order of adding cursors
SpawnMultiCursor{Up,Down} currently works in a tricky way: instead of
creating a new cursor above or below, it moves the current "primary"
cursor above or below, and then creates a new cursor below or above the
new position of the current cursor (i.e. at its previous position),
creating an illusion for the user that the current (top-most or
bottom-most) cursor is a newly spawned cursor.
This trick causes at least the following issues:
- When the line above or below, where we spawn a new cursor, is shorter
than the current cursor position in the current line, the new cursor
is placed at the end of this short line (which is expected), but also
the current cursor unexpectedly changes its x position and moves
below/above the new cursor.
- When removing a cursor in RemoveMultiCursor (default Alt-p key), it
non-intuitively removes the cursor which, from the user point of view,
is not the last but the last-but-one cursor.
Fix these issues by replacing the trick with a straightforward logic:
just create the new cursor above or below the last one.
Note that this fix has a user-visible side effect: the last cursor is
no longer the "primary" one (since it is now the last in the list, not
the first), so e.g. when the user clears multicursors via Esc key, the
remaining cursor is the first one, not the last one. I assume it's ok.
* SpawnMultiCursorUp/Down: move common code to a helper fn
* SpawnMultiCursorUp/Down: honor visual width and LastVisualX
Make spawning multicursors up/down behave more similarly to cursor
movements up/down. This change fixes 2 issues at once:
- SpawnMultiCursorUp/Down doesn't take into account the visual width of
the text before the cursor, which may be different from its character
width (e.g. if it contains tabs). So e.g. if the number of tabs before
the cursor in the current line is not the same as in the new line, the
new cursor is placed at an unexpected location.
- SpawnMultiCursorUp/Down doesn't take into account the cursor's
remembered x position (LastVisualX) when e.g. spawning a new cursor
in the below line which is short than the current cursor position, and
then spawning yet another cursor in the next below line which is
longer than this short line.
* SpawnMultiCursorUp/Down: honor softwrap
When softwrap is enabled and the current line is wrapped, make
SpawnMultiCursor{Up,Down} spawn cursor in the next visual line within
this wrapped line, similarly to how we handle cursor movements up/down
within wrapped lines.
* SpawnMultiCursorUp/Down: deselect when spawning cursors
To avoid weird user experience (spawned cursors messing with selections
of existing cursors).
It is useful to be able to use mouse not only for adding new cursors
but also for removing them. So let's modify MouseMultiCursor behavior:
if a cursor already exists at the mouse click location, remove it.
If ~/.config/micro/plug directory contains a plugin with the same name
as a built-in plugin, the expected behavior is that the user-defined
plugin in ~/.config/micro/plug is loaded instead of the built-in one.
Whereas the existing behavior is that the built-in plugin is used
instead of the user-defined one. Even worse, it is buggy: in this case
the plugin is registered twice, so its callbacks are executed twice
(e.g. with the autoclose plugin, a bracket is autoclosed with two
closing brackets instead of one).
Fix this by ensuring that if a plugin with the same name exists in the
~/.config/micro/plug directory, the built-in one is ignored.
Fixes#3029

* Fixed newline format detection for files not ending with a newline
Files with Windows-style line endings were being converted to
Unix-style if the file did not end with a newline
* Updated file format detection fix for consistency
Similarly to the crash fixed by #2967, which happens if sudo failed,
a crash also happens when sudo even fails to start. The reason for
the crash is also similar: nil dereference of screen.Screen caused by
the fact that we do not restore temporarily disabled screen.
To reproduce this crash, set the `sucmd` option to some non-existing
command, e.g. `aaa`, and try to save a file with root privileges.
* Fix panic due to invalid regex in a syntax file
When a user's custom syntax file has a malformed filename regex or
header regex, MakeHeaderYaml() returns error but we do not properly
handle it, which results in a panic due to a dereference of the `header`
pointer which is nil:
Micro encountered an error: runtime.errorString runtime error: invalid memory address or nil pointer dereference

* Do not ignore invalid filename regex error in a syntax file
When the filename regex in a syntax file is malformed but the subsequent
header regex is correct, the filename regex error gets silently ignored,
since the `err` value is overwritten by the subsequent successful header
regex result.
Add HistorySearchUp and HistorySearchDown actions which are similar to
HistoryUp and HistoryDown but search for the prev/next history item
whose beginning matches the currently entered text in the infobuffer
(more precisely, the text before cursor).
Also fixed the following issue: if we scrolled to an older history item
and then edit the infobuffer, this older item gets modified.
We should not edit old history entries. So in this case set HistoryNum
to the last (newly added) item and modify the last item.
On modern Linux systems, it can take 30 seconds for
the data to actually hit the disk (check
/proc/sys/vm/dirty_expire_centisecs).
If the computer crashes in those 30 seconds, the user
may end up with an empty file as seen here:
https://github.com/neovim/neovim/issues/9888
This is why editors like vim and nano call
the fsync syscall after they wrote the file.
This syscall is available as file.Sync() in Go.
Running strace against micro shows that fsync is
called as expected:
$ strace -f -p $(pgrep micro) -e fsync
strace: Process 3284344 attached with 9 threads
[pid 3284351] fsync(8) = 0
Also, we now catch errors returned from w.Flush().
* 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
Bump zyedidia/terminal, which is the actual dependency. We can get the
information we need from the Term's pty file rather than using a buffer
connected to stdout.
Fixes#2775
Add color groups for displaying statuslines of inactive split panes
and the suggestions menu with colors different from the statusline
of the active pane.

Since now bufpane handles mouse move and release events generically and
separately from mouse press events, that creates a mess when we dispatch
a mouse press event to an inactive pane without making it active.
For example:
1. Click the right button on an inactive pane. It remains inactive.
2. Then click the left button on it. It becomes active, and an
unexpected text selection appears.
The reason is that the release event for the first click was dispatched
to a wrong pane - the (then) active one, so the (then) inactive pane
didn't get the release event and treats the second click not as a mouse
press but as a mouse move.
The simplest way to fix it is to avoid this scenario entirely, i.e.
always activate the pane when clicking any mouse button on it, not just
the left button.
For mouse wheel motion events we keep the existing behavior: the pane
gets the event but doesn't become active. Mouse wheel motion events are
not affected by the described issue, as they have no paired "release"
events.
