Saving a buffer every time without even checking if it was modified
(i.e. even when the user is not editing the buffer) is wasteful,
especially if the autosave period is set to a short value.
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.
Instead of passing a single brace pair to FindMatchingBrace(), make it
traverse all brace pairs in buffer.BracePairs on its own.
This has the following advantages:
1. Makes FindMatchingBrace() easier to use, in particular much easier
to use from Lua.
2. Lets FindMatchingBrace() ensure that we use just one matching brace -
the higher-priority one. This fixes the following issues:
([foo]bar)
^
when the cursor is on `[`:
- Both `[]` and `()` pairs are highlighted, whereas the expected
behavior is that only one pair is highlighted - the one that the
JumpToMatchingBrace action would jump to.
- JumpToMatchingBrace action incorrectly jumps to `)` instead of
`]` (which should take higher priority in this case).
In contrast, with `((foo)bar)` it works correctly.
When updateDiffSync() is called asynchronously, it should lock the
line array when calling Bytes(), to prevent race if the line array is
being modified by the main goroutine in the meantime.
The callback passed to UpdateDiff() is superfluous: in the synchronous
case screen.Redraw() is not needed anyway (since the screen is redrawn
at every iteration of the main loop), and in the asynchronous case
UpdateDiff() can just call screen.Redraw() directly.
Ensure that the selection start is always before the selection end,
regardless of the direction of a mouse selection, to make
h.Cursor.Deselect() handle its `start` argument correctly.
This makes the cursor behavior after mouse selections consistent with
the cursor behavior after keyboard selections.
Fixes#3055
Previously `CursorDown` function called `Deselect` with a wrong
argument which lead to the situation when cursor was moved to the
start instead of the end of the selection

Fix the following buggy behavior:
1. bind "<n><a>" to the Paste action in the command bar
2. open a split pane, type some text and press Ctrl-q to close it
3. answer "n" to the "Save changes before closing?" prompt
4. press Ctrl-e to open the command prompt and press "a"
-> result: instead of inserting the "a" letter, clipboard is pasted.
It is not really defined what is the meaning of this return value.
Currently this value is always true. And even if this value actually
meant something (for example, the result of the last executed action
in the chain), we should not use this value in HandleEvent(). The key
event handling logic should behave the same regardless of whether the
action triggered by this key succeeded or not.
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.
Fix `set filetype unknown` not working as expected in the following
scenario:
1. open foo.txt (no filetype detected) -> ft is `unknown`, highlighted
with default.yaml, as expected
2. `set filetype go` -> ft is `go`, highlighted with go.yaml as expected
3. `set filetype unknown` -> ft is still `go`, still highlighted with
go.yaml (whereas expected behavior is: ft is `unknown`, highlighted
with default.yaml)
Fix that by always updating b.SyntaxDef value, not reusing the old one.
This also makes the code simpler and easier to understand.
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().
We should call the onSetActive callback not only when switching to
another bufpane within the same tab but also when switching to another
tab.
Note on implementation details:
- In SetActive() we need to check if the tab is not already active, to
avoid calling onSetActive for an already active bufpane.
- We cannot check that just by checking if the tab index passed to
SetActive() is different from the current active tab index, since this
index may remain the same even if the tab itself is different (in the
case of removing a tab from the tablist). So we need to check the tab
itself, not just the tab index. So we introduce the isActive field,
to track the tab's active state in the Tab structure itself.
This is necessary as a preparation to introduce a lock for the whole LineArray.
The modification can then be done without trying to lock the same lock twice.

Adding InitRuntimeFiles() to buffer_test.go has changed the behavior
of this test: now it tests not just buffer editing per se, but also
how well buffer editing works together with syntax highlighting (since
InitRuntimeFiles() loads syntax files, and many of the test buffers
match the json header pattern in the json.yaml syntax file, so they are
"highlighted" as json). This revealed long existing races between
buffer editing and syntax highlighting.
Until we fix those races, temporarily disable InitRuntimeFiles() in this
test.
When initializing runtime files (syntax files etc) in tests, initialize
built-in runtime files only, to ensure that the tests are not affected
by whatever is in ~/.config/micro/ on the test machine.
micro_test.go already ensures that, by using its own temporary directory
as an (empty) config directory. So we only need to fix buffer_test.go
and rtfiles_test.go. In those tests, don't repeat the same dance with
a temporary directory, instead just ignore the config directory.
Adding InitPlugins() to tests has caused noisy error logs when running
the buffer_test.go test (although the test result is still PASS):
2024/03/23 15:14:30 Plugin does not exist: autoclose at autoclose : &{autoclose autoclose <nil> [runtime/plugins/autoclose/autoclose.lua] false true}
2024/03/23 15:14:30 Plugin does not exist: comment at comment : &{comment comment <nil> [runtime/plugins/comment/comment.lua] false true}
2024/03/23 15:14:30 Plugin does not exist: diff at diff : &{diff diff <nil> [runtime/plugins/diff/diff.lua] false true}
2024/03/23 15:14:30 Plugin does not exist: ftoptions at ftoptions : &{ftoptions ftoptions <nil> [runtime/plugins/ftoptions/ftoptions.lua] false true}
...
These errors are caused simply by the fact that plugins are initialized
but not loaded. Adding config.LoadAllPlugins() to buffer_test.go "fixes"
this problem.
However, at the moment it doesn't seem a good idea to load plugins in
buffer_test.go, since buffer_test.go doesn't properly initialize Lua. It
only does ulua.L = lua.NewState() but doesn't do the other stuff that
init() in cmd/micro/initlua.go does. As a result, plugins will not be
able to do anything correctly.
So in order to initialize Lua correctly we need to be inside cmd/micro/,
so we cannot do it in buffer_test.go or any other tests except
micro_test.go.

* Revert "Don't expose Go timers directly to lua"
This reverts commit 4ffc2206ee.
Reason for revert: some plugins happen to use raw Go timers via
time.AfterFunc(), in an unsafe way (without synchronizing their
async code with micro). Let them keep doing that for now, in an
unsafe way but at least without immediate crashes.
Fixes#3209
* Add TODO about Go timers deprecation
`unknown` is a valid value for the `filetype` option (and executing
`set filetype unknown` does what is expected: it forces filetype
autodetection). So let's add `unknown` to the autocomplete suggestions
for `filetype`, along with actual filetypes.
Replacing header patterns with signature patterns was a mistake, since
both are quite different from each other, and both have their uses. In
fact, this caused a serious regression: for such files as shell scripts
without *.sh extension but with #!/bin/sh inside, filetype detection
does not work at all anymore.
Since both header and signature patterns are useful, reintroduce support
for header patterns while keeping support for signature patterns as well
and make both work nicely together.
Also, unlike in the old implementation (before signatures were
introduced), ensure that filename matches take precedence over header
matches, i.e. if there is at least one filename match found, all header
matches are ignored. This makes the behavior more deterministic and
prevents previously observed issues like #2894 and #3054: wrongly
detected filetypes caused by some overly general header patterns.
Precisely, the new behavior is:
1. if there is at least one filename match, use filename matches only
2. if there are no filename matches, use header matches
3. in both cases, try to use signatures to find the best match among
multiple filename or header matches
The original meaning of foundDef was: "we already found the final syntax
definition in a user's custom syntax file". After introducing signatures
its meaning became: "we found some potential syntax definition in a
user's custom syntax file, but we don't know yet if it's the final one".
This makes the code confusing and actually buggy.
At least one bug is that if we found some potential filename matches in
the user's custom syntax files, we don't search for more matches in the
built-in syntax files. Which is wrong: we should keep searching for as
many potential matches as possible, in both user's and built-in syntax
files, to select the best one among them.
Fix that by restoring the original meaning of foundDef and updating the
logic accordingly.
* rtfiles: Initialize all-/realFiles and Plugins in InitRuntimeFiles
* command: Reload plugins at ReloadCmd too
* command: Don't reload plugins in case of ReloadConfig()
* rtfiles: Split InitRuntimeFiles() into one func for assets and one for plugins
* rtfiles: Remove the unnecessary init function
With this modification the InitRuntimeFiles() and InitPlugins() (if needed)
must be called first, otherwise uninitialized runtime file variables are most
likely.
InfoBar should really receive the resize event, to know the window width
in order to do horizontal scrolling of the command line when it doesn't
fit in the screen. Although currently it doesn't scroll the command line
at all (see issue #2527) and just ignores the resize event, but we
should fix that anyway, so let's forward the resize event to it.

Exposing locking primitives to lua plugins is tricky and may lead to
deadlocks. Instead, if possible, it's better to ensure all the needed
synchonization in micro itself, without leaving this burden to lua code.
Since we've added micro.After() timer API and removed exposing Go timers
directly to lua, now we (probably?) have no cases of lua code possibly
running asynchronously without micro controlling when it is running. So
now we can remove lua.Lock.
This means breaking compatibility, but, until recently lua.Lock wasn't
workable at all (see #2945), which suggests that it has never been
really used by anyone. So it should be safe to remove it.
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.
Passing options via micro -option=value in the command line should only
temporarily override the option value for the current micro session,
not change it permanently in settings.json. But currently it wrongly
writes it to settings.json in the case when the value passed via command
line is the default value of this option, while the current permanent
setting in settings.json is a non-default value.
Fixes#3005
