sprintf-kit

sprintf-kit is a JavaScript library providing a modular `printf` format string parser and basic formatter. It allows developers to create custom `sprintf`-like functions by explicitly configuring specific modifier resolvers (e.g., for `%s`, `%d`). The library's core is its detailed `printf` syntax parser, which breaks down format strings into literals and placeholder metadata. It also offers a format function generator and a parts resolver generator, enabling granular control over how strings are processed and substitutions are applied. Currently at version 2.0.2, the package has seen infrequent but recent maintenance, with the last major update (v2.0.0) occurring in 2018, focusing on internal structure and advanced parsing capabilities. Its modularity and explicit modifier configuration differentiate it from simpler `sprintf` implementations that might bundle all modifiers by default.
