VSCode-PVS is a new integrated development environment for creating, evaluating and verifying PVS specifications. The environment redefines the way developers interact with PVS, and better aligns the PVS front-end to the functionalities provided by development environments used by software developers.
The main functionalities provided by the environment are as follows:
-
Syntax highlighting: PVS keywords and library functions are automatically highlighted.
-
Autocompletion and code snippets: Tooltips suggesting function names and language keywords are automatically presented in the editor when placing the mouse over a symbol name. Code snippets are provided for frequent modeling blocks, e.g., if-then-else.
-
Hover information for symbol definitions: Hover boxes providing information about identifiers are automatically displayed when the user places the cursor over an identifier.
-
Go-to definition: Click on the name of the identifier while holding down the Ctrl key to jump to the location where the identifier is declared.
-
Live diagnostics: Parsing is automatically performed in the background, and errors are reported in-line in the editor. Problematic expressions are underlined with red wavy lines. Tooltips presenting the error details are shown when the user places the cursor over the wavy lines.
-
Workspace Explorer: Interactive tree view showing all theories in the current workspace, name and status of theorems and typecheck conditions.
-
Proof Explorer + Integrated Terminal: Interactive tree view for viewing and editing the current proof. An integrated terminal allows interaction with the theorem prover. Auto-completion is provided (using the TAB key) for prover commands, as well as access to the commands history.
