A new Java scratch was an empty file that couldn't run until a class and
main method were typed in. Languages can now define `scratch-template` in
`languages/<id>.toml`; a new scratch gets that content with the caret at
`$END$`.
- Java, Kotlin, Go, Rust, C and C++ get a runnable `main`.
- Other languages still start empty.
Opening a .class file showed binary content. Class files from library jars, project output directories, navigation, Go to Class and debugger frames now all go through one route to JDT class documents:
- Library classes open the attached source, or the FernFlower decompilation when there is none, read-only and marked as decompiled. java-debug's decompiled-source support is enabled, so breakpoints set in decompiled code map to the original lines and hit, and stepping into such classes lands on the right line.
- Output-directory classes (target/classes, build/classes) open their project source when it exists; otherwise the decompiled text is shown read-only with breakpoints disabled, because jdt.ls returns no line mapping for classes outside the Java model.
- The preferred content provider id is corrected to fernflowerContentProvider (attached sources still win), and the decompiled marker recognises the current FernFlower header.
Verified on macOS with a Maven project: library class from Libraries and Go to Class, breakpoint hit and step into decompiled code, output class with and without source. Not run on Windows, Linux or Gradle projects.
Fixes#394
Source and Test roots marked in Project Structure never reached jdtls, so projects without Maven, Gradle or Eclipse metadata relied on jdtls's inference. That inference could treat a package directory as the source root, which gave wrong-package and unresolved-import errors in the editor and in Run.
Marked roots now go to jdtls as `java.project.sourcePaths`. Unmarked projects use `src/main/java` and `src/test/java`, or `src`; other layouts keep the inference. Changing the roots restarts only jdtls, with a separate workspace per source model, because a cached invisible project does not pick up new folders. Maven, Gradle and Eclipse projects keep their own model. Ant layouts count as unmanaged, since jdtls has no Ant importer.
Settings sent to jdtls are now merged the same way for initialization, configuration requests and change notifications. A Run with no editor open finds a trigger file inside the source roots so the project still imports.
* feat(editor): Drag tabs and files between split panes
HTML5 drag and drop never reaches the webview while native file drop is
enabled, so tab, project-file and changelist drags did nothing. They now
run on pointer events:
- Drag an editor tab onto another pane, or onto a pane's edge to split it.
- Drag files from the Project view into an editor pane (center opens them
there, an edge opens them in a new split).
- Drag files between changelists in the Commit view.
- "Drag-and-drop with Alt pressed only" applies to tabs and stripe buttons.
* fix(lsp): Deliver server settings and start servers on a supported JDK
- workspace/configuration answers a server's own section (basedpyright)
from its settings block; basedpyright runs in "standard" mode and keeps
auto search paths on, so `src/` layouts resolve from `tests/`.
- jdtls: formatting follows the editor indent, calls complete without
guessed arguments, and JDK internals stay out of completion.
- `max-java` in a language server config picks an installed JDK no newer
than that (kotlin-language-server fails on JDK 25).
- Server initialization may take up to 5 minutes (first Gradle import).
- `lsp_resend_diagnostics` re-emits stored diagnostics after a reload.
- Spelling only checks declared names (not called methods like
`substring`) and accepts plurals of known software terms.
* feat(editor): Quick fixes, completion and navigation while typing
Quick fixes
- Errors get a red quick-fix bulb; Apply Quick Fix (⌥⇧↵) fixes the most
severe problem at the caret, and the error hover offers the fix directly.
- Code generated by a code action is re-indented to the file's style.
- Python: Implement abstract methods (⌃I or the bulb) from the bases.
- Duplicate code actions are listed once.
Completion
- Overloads sharing a name, and a name importable from several modules,
are no longer merged into one entry.
- Auto-import entries show the module they import from.
- Call snippets without a stop (`new ArrayList<>()`) leave the caret inside
the parentheses with parameter info, or past them when nothing takes
arguments; parameter info also opens after server call snippets.
- The selected item is resolved ahead of acceptance, so its auto-import
is applied (rust-analyzer).
Navigation and diagnostics
- Language server requests wait for pending edits, so Go to Declaration
right after typing answers for the current text; an empty answer right
after an edit is retried while the server catches up.
- Diagnostics come back after a window reload; error underlines stay
visible under typo / unused highlighting.
- Implementation gutter markers no longer refresh in a loop while the
server reports progress.
- A missing alternative server no longer shows as a server error.
* chore(lint): Skip agent worktrees under .claude
* fix(editor): Skip cancelled LSP requests and limit generated-code reformat
- Requests cancelled while waiting for pending edits are not sent.
- Code generated by an action is reformatted per changed hunk, so an added
import doesn't reformat the code between it and the generated lines.
- A long busy spell caused by a settle refresh re-runs it only once.
- Files dropped on a file row of another changelist move to that changelist.
- Python Implement methods: a nested class without bases ends the lookup,
class bodies continue through unindented string lines, and
`@abstractproperty` stubs become `@property`.
- Resend diagnostics goes through the host ops, and custom servers get
`max_java`.
* fix(editor): Rank the exact type first in Java constructor completion
jdtls appends the call or body to filterText (`String(${0})`); matching
on the label instead lets typing `String` rank `String` above
`StringBuilder` and the other types sharing its sort text.
* fix(editor): List identical completion items once
kotlin-language-server repeats a class once per classpath entry declaring
it, so `String()` and `String` were listed three times each.
* fix(editor): Keep the internal cancellation message out of the UI text catalog
