I pretty like the consistency of esbuild CLI [1]. It has three kinds of options: 1. no-valued option: --example 2. single-valued option: --key=value 3. multi-valued option: --elements:1st --elements:2nd Short options are ruled out, although it accepts the short option -h for discoverability. I particularly like the repeated option pattern for multi-valued options. This avoids ambiguities such as: cli --elements 1st 2nd arg Yes, the ambiguity may be removed by using doubled dashes. However, this is error-prone. I often wondering whether a more familiar syntax for the second and third kinds could be adopted. For instance: --key value --elements 1st --elements 2nd [1] https://github.com/evanw/esbuild https://github.com/evanw/esbuild
