Usage¶
Running WebPPL programs:
webppl examples/geometric.wppl
Arguments¶
Requiring Node.js core modules or WebPPL packages:
webppl model.wppl --require fs
webppl model.wppl --require webppl-viz
Seeding the random number generator:
webppl examples/lda.wppl --random-seed 2344512342
Compiling WebPPL programs to JavaScript:
webppl examples/geometric.wppl --compile --out geometric.js
The compiled file can be run using nodejs:
node geometric.js
Passing arguments to the program¶
Command line arguments can be passed through to the WebPPL program by
placing them after a single --
argument. Such arguments are parsed
(with minimist) and the
result is bound to the global variable argv
.
For example, this program:
display(argv);
When run with:
webppl model.wppl -- --my-flag --my-num 100 --my-str hello
Will produce the following output:
{ _: ['model.wppl'], 'my-flag': true, 'my-num': 100, 'my-str': 'hello' }
Once compiled, a program takes its arguments directly, i.e. the --
separator is not required.
