Ibis is a portable Python dataframe library and multi-backend query engine that provides a unified interface for executing data transformations across diverse compute engines. It functions as a Python SQL expression compiler and dialect transpiler, allowing users to define data logic once and execute it across cloud warehouses, embedded databases, and distributed clusters without rewriting code. The project distinguishes itself through a database backend abstraction that decouples transformation logic from the underlying execution engine. It enables polyglot data workflows by mixing raw SQL s
Provides the ability to filter elements within an array column using a specific predicate.
Go Package of validators and sanitizers for strings, numerics, slices and structs
Returns a new slice containing only elements that pass a specified condition.
Dollar 是一个 Swift 函数式编程库,提供了一套用于集合操作、字符串处理、数学计算以及日期和时间管理的综合工具包。它作为过滤、聚合和重构数组及字典的实用工具集。 该项目实现了柯里化(currying)、记忆化(memoization)和函数组合等函数式编程模式。它还具备链式包装器接口,允许在提取最终结果之前按顺序应用多次数据转换。 该库涵盖了广泛的功能领域,包括文本清理和大小写转换、正则表达式操作,以及阶乘和除数等数学值的计算。它还包含用于解析 Unix 时间戳和计算相对时间偏移的工具。 该工具包通过泛型方法扩展了 Swift 标准库类型,以实现数据转换和聚合。
Provides predicate-based filtering to create subsets of arrays or remove empty values.
Koka 是一种具有代数效应系统的静态类型函数式编程语言。它使用强大的类型系统在编译时验证程序正确性并跟踪副作用。 该语言的特点是采用引用计数编译器,将源代码转换为原生 C 代码,消除了对跟踪垃圾回收器的需求。它采用基于感知的就地更新来减少内存开销,并利用尾递归模 cons 进行常量空间数据结构构建。 该系统提供了一个全面的标准库,涵盖了具有任意精度算术的数值运算、具有高效视图的字符串处理以及用于无限结构的共感数据建模。它还包括对硬件采样执行分析的内置支持,以及用于处理异常和异步流的可组合机制。
Provides predicates for filtering elements and dropping leading items from lists.
