That is, if you say `ESO` then that's like using a +non-magical `E` in: `E|ESO|ZSO`. + +### But I have optional arguments?! + +You can provide more than one signature by separating them with pipes `|`. +If any signature matches the arguments then they'll be considered valid. + +So for example, say you wanted to write a signature for +`fs.createWriteStream`. The docs for it describe it thusly: + +``` +fs.createWriteStream(path[, options]) +``` + +This would be a signature of `SO|S`. That is, a string and and object, or +just a string. + +Now, if you read the full `fs` docs, you'll see that actually path can ALSO +be a buffer. And options can be a string, that is: +``` +path <String> | <Buffer> +options <String> | <Object> +``` + +To reproduce this you have to fully enumerate all of the possible +combinations and that implies a signature of `SO|SS|OO|OS|S|O`. The +awkwardness is a feature: It reminds you of the complexity you're adding to +your API when you do this sort of thing. + + +### Browser support + +This has no dependencies and should work in browsers, though you'll have +noisier stack traces. + +### Why this exists + +I wanted a very simple argument validator. It needed to do two things: + +1. Be more concise and easier to use than assertions + +2. Not encourage an infinite bikeshed of DSLs + +This is why types are specified by a single character and there's no such +thing as an optional argument. + +This is not intended to validate user data. This is specifically about +asserting the interface of your functions. + +If you need greater validation, I encourage you to write them by hand or +look elsewhere. + diff --git a/sandbox/testAppNevena/Front/node_modules/aproba/index.js b/sandbox/testAppNevena/Front/node_modules/aproba/index.js new file mode 100644 index 00000000..fd947481 --- /dev/null +++ b/sandbox/testAppNevena/Front/node_modules/aproba/index.js @@ -0,0 +1,105 @@ +'use strict' +module.exports = validate + +function isArguments (thingy) { + return thingy != null && typeof thingy === 'object' && thingy.hasOwnProperty('callee') +} + +const types = { + '*': {label: 'any', check: () => true}, + A: {label: 'array', check: _ => Array.isArray(_) || isArguments(_)}, + S: {label: 'string', check: _ => typeof _ === 'string'}, + N: {label: 'number', check: _ => typeof _ === 'number'}, + F: {label: 'function', check: _ => typeof _ === 'function'}, + O: {label: 'object', check: _ => typeof _ === 'object' && _ != null && !types.A.check(_) && !types.E.check(_)}, + B: {label: 'boolean', check: _ => typeof _ === 'boolean'}, + E: {label: 'error', check: _ => _ instanceof Error}, + Z: {label: 'null', check: _ => _ == null} +} + +function addSchema (schema, arity) { + const group = arity[schema.length] = arity[schema.length] || [] + if (group.indexOf(schema) === -1) group.push(schema) +} + +function validate (rawSchemas, args) { + if (arguments.length !== 2) throw wrongNumberOfArgs(['SA'], arguments.length) + if (!rawSchemas) throw missingRequiredArg(0, 'rawSchemas') + if (!args) throw missingRequiredArg(1, 'args') + if (!types.S.check(rawSchemas)) throw invalidType(0, ['string'], rawSchemas) + if (!types.A.check(args)) throw invalidType(1, ['array'], args) + const schemas = rawSchemas.split('|') + const arity = {} + + schemas.forEach(schema => { + for (let ii = 0; ii < schema.length; ++ii) { + const type = schema[ii] + if (!types[type]) throw unknownType(ii, type) + } + if (/E.*E/.test(schema)) throw moreThanOneError(schema) + addSchema(schema, arity) + if (/E/.test(schema)) { + addSchema(schema.replace(/E.*$/, 'E'), arity) + addSchema(schema.replace(/E/, 'Z'), arity) + if (schema.length === 1) addSchema('', arity) + } + }) + let matching = arity[args.length] + if (!matching) { + throw wrongNumberOfArgs(Object.keys(arity), args.length) + } + for (let ii = 0; ii < args.length; ++ii) { + let newMatching = matching.filter(schema => { + const type = schema[ii] + const typeCheck = types[type].check + return typeCheck(args[ii]) + }) + if (!newMatching.length) { + const labels = matching.map(_ => types[_[ii]].label).filter(_ => _ != null) + throw invalidType(ii, labels, args[ii]) + } + matching = newMatching + } +} + +function missingRequiredArg (num) { + return newException('EMISSINGARG', 'Missing required argument #' + (num + 1)) +} + +function unknownType (num, type) { + return newException('EUNKNOWNTYPE', 'Unknown type ' + type + ' in argument #' + (num + 1)) +} + +function invalidType (num, expectedTypes, value) { + let valueType + Object.keys(types).forEach(typeCode => { + if (types[typeCode].check(value)) valueType = types[typeCode].label + }) + return newException('EINVALIDTYPE', 'Argument #' + (num + 1) + ': Expected ' + + englishList(expectedTypes) + ' but got ' + valueType) +} + +function englishList (list) { + return list.join(', ').replace(/, ([^,]+)$/, ' or $1') +} + +function wrongNumberOfArgs (expected, got) { + const english = englishList(expected) + const args = expected.every(ex => ex.length === 1) + ?
