vscode-evplus

VSCode language support for Omron Adept eV+ / V+ robot programs (.pg, .v2): syntax highlighting, hover reference, completion, snippets, diagnostics, and an outline of the programs in each file.

Install

From the marketplace (once published): search "eV+ Robot Language".

From source:

npm install
npm run package
./install.sh

install.sh symlinks the extension into ~/.vscode-server/extensions/ (WSL) and copies it into Windows-side .vscode/extensions/ dirs, then reload VSCode.

What you get

• Grammar: control flow, program instructions, real/string/transformation functions, system switches/parameters, word operators, radix numbers (^HFF, ^B1010, ^17), strings, #precision.points, $string.vars, statement labels, .PROGRAM/.END blocks with folding. Keywords match case-insensitively; dotted user variables (req.mb) never false-match keyword tails.
• Hover: the manual's syntax line for the keyword under the cursor (all entries when a name is both instruction and function, e.g. SPEED).
• Completion: 260+ keywords with type and syntax, after any typed prefix.
• Snippets: .PROGRAM, IF, IFELSE, WHILE, DO/UNTIL, FOR, CASE.
• Auto-indent: indents after .PROGRAM/THEN/DO/ELSE/OF/VALUE:/ANY, dedents on END/ELSE/UNTIL/ANY/.END.
• Diagnostics: warns when code after a ; looks like a statement (in eV+ everything after ; is a comment, so a = 1 ; b = 2 only assigns a), when GOTO targets a label that doesn't exist in the program, and on unpaired .PROGRAM/.END.
• Outline: every .PROGRAM in the file appears in the Outline panel and breadcrumbs (jump with Ctrl+Shift+O).

Data generation

data/keywords.json and the grammar's keyword alternations are generated by tools/generate_data.py from an extraction of the eV+ Language Reference Guide (one markdown file per keyword entry, produced with pdftotext -layout from the manual PDF):

python3 tools/generate_data.py <path-to-docs>    # or set EVPLUS_DOCS

The committed data carries each keyword's name, type, and syntax line. If you own the manual, regenerate with --summaries for richer hover text from the manual's Function descriptions (keep that copy local — don't commit it).

Grammar patterns marked "comment": "GEN:<class>" get their match rewritten; the rest of the grammar is hand-maintained.

Tests

npm test        # tokenization snapshots + scope assertions + unit tests
npm run test:update   # refresh snapshots after intentional grammar changes

Visual check: node tools/preview.mjs tests/fixtures/all-constructs.pg out.html renders a file with the real grammar, then node tools/screenshot.mjs out.html out.png.
