This commits replaces a significant part of the code handling these
features. A lot of responsibilities are moved from SketchController to
Sketch, though the code involved is rewritten mostly.
Most of the handling now happens inside Sketch, including various checks
against the new filename. Basically SketchController processes the user
input to decide what needs to be done, and Sketch checks if it can be
done and does it.
If problems occur, an IOException is thrown, using a translated error
message that is shown by SketchController as-is. This might not be the
best way to transfer error messages (regular IOExceptions might contain
less-friendly messages), so this might need further improvement later.
In addition to moving around code and responsibilities, this code also
changes behaviour in some places:
- Because Sketch and SketchFile are now in control of renames and
saves, they can update their internal state after a rename. This
removes the need for reloading the entire sketch after a rename or
save as and allows `Editor.handleOpenUnchecked()` to be removed.
- When renaming the entire sketch, all files used to be saved before
renaming, since the sketch would be re-opened after renaming. Since
the re-opening no longer happens, there is no longer a need to save
the sketch, so any unsaved changes remain unsaved in the editor after
renaming the sketch.
- When renaming or adding new files, duplicate filenames are detected.
Initially, this happened case sensitively, but it was later changed to
use case insensitive matching to prevent problems on Windows (where
filenames cannot differ in just case). To prevent complexity, this
did not distinguish between systems. In commit 5fbf9621f6 (Sketch
rename: allowig a case change rename if NOT on windows), the
intention was to only do case insensitive checking on Windows, but it
effectively disabled all checking on other systems, making the check
not catch duplicate filenames at all.
With this commit, all these checks are done using `File.equals()`
instead of comparing strings, which is already aware of the case
sensitivity of the platform and should act accordingly.
- Some error messages were changed.
- When adding a file, an empty file is not created directly, but only a
SketchFile and EditorTab is added. When the sketch is saved, the file
is created.
- When importing a file that already exists (thus overwriting it),
instead of replacing the SketchFile instance, this just lets the
EditorTab reload its contents. This was broken since the introduction
of EditorTab. The file would be replaced, but not this was not
reflected in the editor, which is now fixed. This change allows
`Sketch.replaceFile()` to be removed.
- When importing a file that does not exist yet (thus adding it), a tab
is now also added for it (in addition to a SketchFile). This was
broken since the introduction of EditorTab, and would result in the
file being added, but not shown in the editor.
This commit adds a `Sketch.renameFileTo()` method, to rename a single
file within the sketch. It would be better to integrate its contents
into `Sketch.renameTo()`, but that does not have access to the `Sketch`
instance it is contained in. This will be changed in a future commit.
This makes a few related changes:
- `FileUtils.replaceExtension()` is introduced to handle replacing the
.pde extension with .ino.
- Instead of iterating .pde files on disk, this iterates SketchFiles in
memory, saving another lookup from filename -> SketchFile later.
- `SketchController.renameCodeToInoExtension()` is removed. Now it no
longer needs to look up the SketchFile and FileUtils handles the
extension replacement, this method did not have any reason to exist
anymore.
- Instead of hardcoding the .pde extension, a new
Sketch.OLD_SKETCH_EXTENSIONS constant is introduced.
Sketch already stores the sketch folder, and the sketch name should be
identical to the folder name. In the case where the filename passed to
the sketch constructor is not the primary .ino file (named after the
sketch), this will slightly change behaviour. However, the calling code
should prevent this from happening, and with the old code, some internal
assumptions were probably violated, so this changes makes handling this
situation a bit more robust.
Since the actual filename passed to Sketch is no longer used, it is no
longer required to pass the name of the primary .ino file. At some
point, the constructor should probably be changed to accept a folder
name instead of a filename, but that would require a lot of changes
to trace this back through the code, so this is something for later.
Previously, it returned a File object, which the Sketch separately
stored from the primary SketchFile. By letting it just return the
SketchFile, and let callers query that for the filename, Sketch does not
need to store the File object itself and there is less chance of info
getting out of sync.
Instead, just the File object when requested. It is not used during
normal operation (just when adding files, or using save as), so no point
in already creating the object in the constructor.
That name more accurately reflects its purpose: It represents a single
file within a sketch. This just updates the class name and variable
names referring to these objects and some comments, so no behaviour
should change.
Previously, the index of the SketchCode instance in the list kept by
Sketch was kept, which isn't really robust.
With this change, Sketch.indexOfCode is no longer needed and is removed.
For determining if the current file was a sketch file, it previously
(indirectly) used a hardcoded "ino" comparison. Now, it uses
`SKETCH_EXTENSIONS` so it also applies to .pde files and the hardcoded
"ino" (and the methods leading up to it) can be removed.
This lets it use FileUtils.splitFilename and reference Sketch.EXTENSIONS
and the new Sketch.DEFAULT_SKETCH_EXTENSION directly, allowing to remove
a few helper functions.
Sketch is now called SketchController, since it didn't really represent
a sketch, but just handled the GUI-related stuff for a given sketch
(note that it is not strictly a controller in the MVC-sense, but it does
have a similar function). SketchData more accurately represented the
actual sketch, so it is now called Sketch. Below, the new names are
used.
Editor now keeps both a current Sketch and SketchController object, and
the Sketch object is created by Editor and passed to SketchController,
instead passing a File and letting SketchController create the Sketch.
Wherever possible, code now uses the Sketch directly (or indirectly,
through the new `SketchController.getSketch()`) and the accessors in
SketchController that merely forwarded to Sketch have been removed.
There are few things that now live in SketchController but should be
moved to Sketch (`isModified()`, `isUntitled()`), so some of the code
still has a dependency on SketchController that should be removed later.
This commit mostly renames classes, methods and variables, it should not
change the behaviour in any way.
