我正在用 NodeJS 编写一个命令行程序,我目前的想法是我希望将参数解析和逻辑放入index.js其中,然后将实际代码放入单独的文件中的函数中。
我遇到的问题是如何编写参数依赖和冲突。出于某种原因cmd,从不包含论点。它仅适用于--help.
我究竟做错了什么?如何在 switch 内部检查其他参数的存在或不存在?
'use strict'
const minimist = require('minimist')
module.exports = () => {
const args = minimist(process.argv.slice(2))
let cmd = args._[0] || 'help'
if (args.version || args.v) {
console.log("Version 0.1")
exit
}
if (args.help || args.h) {
const help =
`
Usage: ddparser [OPTION]... [FILE]...
Parses DD toml files and updates a webpage accordingly.
--help Prints this help page
--validate Validates input file [requires --input]
--k1-dry-run Print K1 changes without doing it [requires --input] [conflicts with --k1-commit]
--k1-commit Commit k1 changes to website [requires --k1-token] [conflicts with --k1-dry-run]
--k1-token K1 token [requires --k1-commit]
--input DD toml file to parse [required]
`
console.log(help)
}
// all args below needs content from the toml file to work
// should exit with error if config.toml isn't found
switch (cmd) {
case 'validate':
// error if --input is not specified
// error if any other argument is given
// read config.toml
// read --input toml file
break
case 'k1-dry-run':
// error if --input is not specified
// error if any other argument is given
// run --validate first and error if it fails
// read config.toml
// read --input toml file
break
case 'k1-commit':
// error if --input is not specified
// error if --k1-token is not specified
// run --validate first and error if it fails
// read config.toml
// read --input toml file
break
