So you've used smartgame to turn your SGF file into a friendly JavaScript object, have you? Now you need a smartgamer to let you navigate and manipulate that smartgame.
For most projects, you'll just want to install smartgamer locally and add it to your project's dependencies in package.json:
$ npm install --save smartgamer
If you want (for whatever reason) to use smartgame anywhere, you can install it globally.
$ npm install -g smartgamer
var sgf = require('smartgame');
var smartgamer = require('smartgamer');
var fs = require('fs');
// Grab an SGF file from somewhere
var example = fs.readFileSync('sgf/example.sgf', { encoding: 'utf8' });
var gamer = smartgamer(sgf.parse(example));
// Go to a specific move
gamer.goTo(4);
// Navigate between moves
gamer.next();
gamer.previous();
// Chain navigation together
gamer.next().next();
gamer.last().previous();
gamer.goTo(4).next(1);
// Get / set comments
gamer.comment();
gamer.comment('Losing move!');
// Get the current node
gamer.node();
// Get the modified smartgame
var newSGF = smartgame.generate(gamer.getSmartgame());
fs.writeFileSync('new-example.sgf', newSGF, { encoding: 'utf8' });
Coming soon! Until then, just checkout index.js. If you care about having this documented, please let me know and I'll make it happen.
