Overview

Package walkers examples TSL tree walking, and helps to generate SQL and MongoDB query filters. sql.Walk and mongo.Walk methods can be used to create such filters.

Squirrel walk code: https://github.com/yaacov/tsl/blob/master/pkg/walkers/sql/walk.go

SQL generation example: https://github.com/yaacov/tsl/blob/master/cmd/tsl_sqlite/main.go

Usage:

filter, err := sql.Walk(tree)

sql, args, err := sq.Select("name, city, state").
     From("users").
     Where(filter).
     ToSql()

BSON walk code: https://github.com/yaacov/tsl/blob/master/pkg/walkers/mongo/walk.go

BSON generation example: https://github.com/yaacov/tsl/blob/master/cmd/tsl_mongo/main.go

Usage:

// Prepare a bson filter
filter, err = mongo.Walk(tree)

// Run query
cur, err := collection.Find(ctx, filter)
