VS Code extension assets for the Procedural Programming Language (.ppl).

Included in v0.6

Everything in v0.3, plus support for newer PPL additions:

Syntax, outline, hover, completion, references, and semantic highlighting for enum declarations and variants
Type-alias parsing (type Name = ...) and module-level let / const globals
Highlighting and literal hover support for 0x / 0b / 0o numbers and _ digit separators
Struct field defaults, shorthand/update-spread snippets, if expressions, and break / continue keywords

Included in v0.3

Everything in v0.2, plus a full set of compiler-aware editor features driven by a lightweight in-extension index of every .ppl file in the workspace (including std/):

Hover — routine signatures with their doc comments, struct layouts, operator declarations, and built-in keyword/type documentation
Outline & breadcrumbs — routines, types (with their fields), and operators via a Document Symbol provider, plus workspace symbol search (Ctrl+T)
Completion — keywords, built-in types, in-scope locals/parameters, all workspace routines (inserted as a call template) and types, literals, and import path completion for std.* and sibling modules
Signature help — parameter hints as you fill in a routine call, with the active argument highlighted (variadics handled)
References (Shift+F12) for routines, types, operators, and locals
CodeLens — a ▶ Run action above main and reference counts above routines and types (toggle with ppl.codeLens.enabled)
Semantic highlighting — scope-aware coloring that distinguishes routine calls, types, parameters, locals, and struct fields (toggle with ppl.semanticHighlighting.enabled)
Sharper diagnostics — squiggles now span the compiler's caret underline (not just one character), and note: lines attach as related information
Compiler-insight commands — PPL: Show LLVM IR / Assembly / AST / Tokens open the corresponding --emit output in a side editor, and PPL: Build Executable links the active file, surfacing errors in the Problems panel
Status bar item — reflects the last compile result (ok / errors / compiling / compiler-not-found); click it to open the output channel

Included in v0.2

Run button (▶ in the editor title bar) and PPL: Run File command/context-menu entry that compiles and runs the active .ppl file with ppl run in an integrated terminal, reusing the configured ppl.compilerPath / ppl.cargoPath resolution

Included in v0.1

Syntax highlighting for current PPL declarations, literals, operators, match, comments, imports, extern routine, intrinsic routine, enum, type aliases, globals, unsigned scalars, pointers, arrays, function-pointer types, and packed varargs (...)
Language configuration for // comments, bracket matching, auto-closing pairs, number suffixes, and basic indentation
Snippets for routine, procedures, extern routine, packed varargs, type, enum, type aliases, globals, if/else, if expressions, while ... do, do ... while, for ... while ... do, match, operators, imports, function pointer types, casts, struct update, and raw byte pointers
Go to Definition (Ctrl+Click / F12) for local variables, for initializers, routine parameters, top-level routines/externs, type names/usages, user-defined operators, and imported modules
Compiler diagnostics in the editor for saved .ppl files, using the project compiler output

What this does not include

Language Server Protocol integration (features run in-process from the extension's own index rather than a separate server)
In-memory semantic diagnostics/type checking for unsaved files (diagnostics run the real compiler on save)
Rename and formatting
Type inference, so member completion after . is intentionally left off rather than guessed

Develop and run

Open this editors/vscode folder.
Install extension development dependencies in your VS Code environment if needed.
Press F5 in VS Code to launch an Extension Development Host.
Open any .ppl file in the new window.

If you prefer packaging later, this folder is already structured as a standalone extension with package.json, syntaxes/, snippets/, and language-configuration.json.
