- extract the open logic into `openFile()` and return a `wrappedFile`
- extract the closing logic into `Close()` and make a method of `wrappedFile`
- rename `writeFile()` into `Write()` and make a method of `wrappedFile`
This allows to use the split parts alone while keeping overwriteFile() as simple
interface to use all in a row.
In `ReloadSettings()` the `filetype` can change upon globbed path given by
the `settings.json` or by identifying a different `filetype` based on the
file name given or pattern present inside the file.
To prevent further recursion caused by checking the `filetype` again, its
processing stops here and isn't considered in `DoSetOptionNative()`
once again where the callbacks are usually triggered.
Like in NewBuffer(), we need to update glob-based local settings
before updating the filetype, since the filetype itself may be among those
glob-based local settings.
* `UpdatePathGlobLocals()`
* to apply the settings provided within e.g. "/etc/*": {}
* `UpdateFileTypeLocals()`
* to apply the settings provided within e.g. "ft:shell": {}
We don't need to call `InitLocalSettings()` twice any longer.
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.
Add `matchbraceleft` option to allow disabling the default behavior
matching not just the brace under cursor but also the brace to the left
of it (which is arguably convenient, but also ambiguous and
non-intuitive). With `matchbraceleft` disabled, micro will only match
the brace character that is precisely under the cursor, and also when
jumping to the matching brace, will always move cursor precisely to the
matching brace character, not to the character next to it.
Nota bene: historical journey:
- There was already a `matchbraceleft` option introduced in commit
ea6a87d41a, when this feature (matching brace to the left) was
introduced first time. That time it was matching _only_ the brace
to the left, _instead_ of the brace under the cursor, and was
disabled by default.
- Later this feature was removed during the big refactoring of micro.
- Then this feature was reintroduced again in commit d1e713ce08, in
its present form (i.e. combined brace matching both under the cursor
and to the left, simulating I-beam cursor behavior), and it was
introduced unconditionally, without an option to disable it.
- Since then, multiple users complained about this feature and asked
for an option to disable it, so now we are reintroducing it as an
option again (this time enabled by default though).
Similarly to how we force `fastdirty` to true when opening a large file
(when creating the buffer), force it also when reopening a file, in case
the file on disk became large since we opened it.
