pnpm run package
code --install-extension dist/pine-tools-*.vsix

Reload VS Code window after install. Use pnpm run watch for live development.

pnpm test

CLI

node dist/packages/cli/src/cli.js file.pine

Or after install:

pine-validate file.pine

LSP Server

Library Imports

Pine libraries (import User/Library/Version) have no discoverable source. Use /// @source to enable IntelliSense:

/// @source ./libs/my-library.pine
import User/MyLibrary/1 as myLib

x = myLib.myFunction(close)  // completions, hover, go-to-definition

Place the directive immediately before the import. Path is relative to current file.

Acknowledgements

vendor/ contains the source of published Pine Script libraries, used only to derive each library's exported-symbol set (pine-data/v6/libraries.json) so the linter can validate imported-library member calls (flagging calls to functions a library does not export). Each file retains its original license header.

All vendored libraries are licensed under the Mozilla Public License 2.0 (https://mozilla.org/MPL/2.0/) by their respective authors. Libraries published under non-redistributable or unstated terms are deliberately not vendored; the linter stays lenient on those imports.

TradingView's own ta and RelativeValue libraries are TradingView's pure-Pine reference implementations. The community libraries are the work of, in alphabetical order: algotraderdev, andre_007, Bjorgum, boitoki, DevLucem, HeWhoMustNotBeNamed, HoanGhetti, HPotter, jason5480, jdehorty, jmosullivan, kaigouthro, LonesomeTheBlue, loxx, LucF, LudoGH68, PineCoders, reees, RicardoSantos, robbatt, TFlab, toodegrees, Trendoscope, and ZenAndTheArtOfTrading.
