Add PSC (.psc) indexing and share TclOO class metadata across files so class
definitions discovered via PSC layers can be used for completions, signature
help, inlay hints, and "go to definition". Key behavior changes:
- Client file watcher now includes *.psc and .vscode launch paths/tests updated
to use the postprocessor test folder; .gitignore updated to ignore that folder.
- Server watches .psc changes and refreshes a PSC script index; new
tools/tcloo_navigation.py exposes tcloo_definition used by the language server
to resolve cross-file class/constructor/method definitions.
- Language server uses class_snapshot(document.path) when producing TclOO
completions, signature help, and inlay hints so resolved class metadata is
available across files.
Also includes related docs/changelog updates, minor code formatting cleanups,
and added tests for PSC/TclOO behavior.
Add conservative, document-local TclOO type inference and tooling so the server
can offer method completions, signature help, and inlay parameter hints for
statically resolvable TclOO receivers (including `new`/`create`, `my`, and
simple return-chains). Also surface class names as completion items and emit
semantic tokens for class declarations/references.
Notable changes:
- New tcloo_* tools: completion, symbols, and argument parsing; integrated into
on_completion, signature_help, inlay hint generation and semantic token
highlighting. Completions are returned early when an OO receiver context is
detected.
- Use a completion-friendly parser fallback when the main AST fails (TclSyntaxError)
so editing-in-progress code still yields useful completions.
- Add CompletionItemKind.Class to command kinds, exclude class items from the
poco completion name cache, and include new unit tests for the TclOO helpers.
This adds tooling to statically extract Tcl variable names from syntax
trees without evaluating substitutions, enabling better completions
for array elements and plain variables. The new helpers are wired
into the completion and navigation flows and are supported by tests
covering array keys and substitutions.
- Introduce variable_names.py with variable_name() and array_key_parts()
- Wire static name extraction into completion and symbol indexing
- Add tests for array key completion with substitutions
The generated event handler snippet now declares the proc with an args block.
This enables parameters to be referenced within the handler body.

for Tcl to provide variable, procedure, namespace, and path suggestions.
- Adds snippet-backed commands and arguments for Tcl blocks and paths.
- Refactors tcl_argument_completion and updates the LSP to use dynamic path,
variable, and namespace completions with snippet kinds.
- Introduced a Tcl command-aware completion engine and wired to LSP.
- Added a new module with Tcl commands, options, and contextual matching.
- Updated completion to favor command-aware items and args.
Adds context-aware completion ranking and document highlights for Tcl.

Adds LSP call hierarchy support for TCL procedures and MOM events.
A symbol index and identity logic underpin incoming and outgoing calls.
LSP call hierarchy features are wired and changelog/README updated.
- Implement data encoding for call hierarchy items and identity restoration
- Wire LSP server to expose prepare_call_hierarchy, incoming_calls, and outgoing_calls
- Add tests for cross-file calls and edge cases
The changes align the project with the 2025.0.0 lsprotocol
release, removing the old backport and updating type hints
in the protocol hooks to use Sequence where appropriate. The
dist-info and packaging metadata for older lsprotocol
versions are replaced with the new 2025.0.0 artifacts.
- Remove exceptiongroup backport used on Python <3.11
- Use Sequence instead of List in LS protocol hooks
- Replace old dist-info with 2025.0.0 metadata
This change removes outdated development and debugging guidance
from the README and streamlines the licensing note. It also deletes
the embedded debugger license file and relies on the main LICENSE
file for terms.
- Remove outdated debugging guidance from README
- Delete embedded debugger license file and rely on LICENSE
Embed the NX Tcl Remote Debugger into the NX Postprocessor extension.
Add a new debugging client, protocol, and adapter logic to
drive attach/launch, breakpoints, stepping, and evaluation
via the runtime adapter.
- Introduced a client debugger with a new adapter and protocol
- Wired attach/launch, breakpoints, stepping, and evaluation
- Updated docs and licensing to reflect the embedded debugger
This change adds cached and incremental analysis for the LSP
server to improve responsiveness. The client now debounces
diagnostic updates to avoid excessive recomputation. The
server introduces per-document line caches and various
caches for completions, inlay hints, and metadata to
support faster, incremental updates.
- Debounce diagnostics on text changes to reduce noise.
- Add caches for completions, inlay hints, and metadata.
- Introduce incremental analysis with per-document line caches.
Adds configurable inlay hints for TCL procedures and merges signatures from built-ins and workspace files. The feature supports parameterNames and suppressWhenArgumentMatchesName and respects an optional range filter and current-file priority.
- Introduces built-in and custom inlay hint builders
- Honors inlayHints parameterNames and suppression options
- Adds tests validating hints, ranges, and priority rules
This adds a small DSL-aware helper to extract CDL event
declarations and generate a ready-to-use snippet. It also
extends hover support to show the snippet and parameter
hints for CDL events, improving developer productivity.
- Generate a MOM event handler scaffold and local vars
- Hover shows the generated snippet and mom_ parameter hints
Adds an end-to-end Python debug workflow for the extension.
Includes a new prepare-debug.ps1 script and a VS Code task.
Extends the Python server and extension to coordinate a debug session and safe startup.
- Add prepare-debug.ps1 and a VS Code task to build the debug bundle
- Enable Python debug wiring in the server and tests
- Ensure a single stable Python debug session during startup
The changes introduce a Tcl symbol index powering LSP navigation
features across the workspace. A navigation API exposes
snapshots and update hooks, enabling goto-definition,
references, and rename using the index. Background indexing
now watches Tcl files and rebuilds the index to stay in sync.
- Add Tcl symbol index and navigation snapshot API
- Wire go-to-definition, references, and rename using the index
- Watch Tcl files and refresh the index in the background
Adds a thread-safe incremental index and snapshot API for LSP.
Introduces cache invalidation and file operation hooks for delete
and rename. This keeps indices in sync with disk changes.
Supports reindexing TCL files from disk when needed.
- Adds workspace file change handlers to sync indices on delete/rename.
- Introduces locking and snapshot helpers to safely access shared state.
- Refactors to invalidate caches on edits and reindex TCL files.
Adds a signature help system for TCL commands.
The LSP server now exposes signature help for custom and
built-in MOM procedures, enabling parameter hints while editing.
Tests and documentation were added to cover common usage.
- Adds signature_help module to parse and present signatures
- Integrates with LSP server to provide signature help on the client
- Adds tests for custom and built-in procedures
The formatter now calculates and passes explicit leading and trailing whitespace around expression content to the `_brace` method. This ensures correct rendering of single-line expressions that include braces.
- Move TCL folding range computation from client to language server, avoiding duplicate regions.
- Serialize language server restarts to prevent multiple server instances running concurrently.
- Pin server-side Python dependencies to specific minor versions for improved stability and predictability.
- Make debug server connection non-fatal, allowing the language server to start even if the debugger isn't attached.
- Optimize semantic token generation by caching Tclint plugin commands.
