Javascript 将任意字符串插入sweet.js输出
如何在sweet.js生成的输出中插入任意字符串 这对于以编程方式执行基于不同条件的字符串不同的操作非常有用 例如,在下面代码的第25行,我想插入一个字符串作为结果 sweet.js代码:Javascript 将任意字符串插入sweet.js输出,javascript,sweet.js,Javascript,Sweet.js,如何在sweet.js生成的输出中插入任意字符串 这对于以编程方式执行基于不同条件的字符串不同的操作非常有用 例如,在下面代码的第25行,我想插入一个字符串作为结果 sweet.js代码: import { produceNormalParams } from './abc/produceNormalParams' import { produceParamChecks } from './abc/produceParamChecks' import { produce
import { produceNormalParams } from './abc/produceNormalParams'
import { produceParamChecks } from './abc/produceParamChecks'
import { produceInnerChecks } from './abc/produceInnerChecks'
syntax function = function(ctx) {
let funcName = ctx.next().value;
let funcParams = ctx.next().value;
let funcBody = ctx.next().value;
//produce the normal params array
var normalParams = produceNormalParams(funcParams)
//produce the checks
var paramChecks = produceParamChecks(funcParams)
//produce the original funcBody code
var inner = produceInnerChecks(funcParams)
var someArbitraryString = "console.log('hey')"
//put them together as the final result
var result = #`function ${funcName} ${normalParams} {
${someArbitraryString}
${paramChecks}
${inner}
}`
return result
}
输入示例:
module.exports = multiply
function multiply(a:array,b,c:array) {
return a * c
}
示例输出:
// Example Output
module.exports = multiply;
function multiply(a_31, b_32, c_33) {
console.log('hey')
if (Object.prototype.toString.call(a_31) !== "[object Array]") throw new Error("Must be array:" + a_31);
if (Object.prototype.toString.call(c_33) !== "[object Array]") throw new Error("Must be array:" + c_33);
return a_31 * c_33;
}
虽然不能在语法模板中插入任意字符串,但可以插入其他语法模板
import { produceNormalParams } from './abc/produceNormalParams' for syntax;
import { produceParamChecks } from './abc/produceParamChecks' for syntax;
import { produceInnerChecks } from './abc/produceInnerChecks' for syntax;
syntax function = function(ctx) {
let funcName = ctx.next().value;
let funcParams = ctx.next().value;
let funcBody = ctx.next().value;
//produce the normal params array
var normalParams = produceNormalParams(funcParams);
//produce the checks
var paramChecks = produceParamChecks(funcParams);
//produce the original funcBody code
var inner = produceInnerChecks(funcParams);
var someArbitrarySyntax = #`console.log('hey')`;
//put them together as the final result
var result = #`function ${funcName} ${normalParams} {
${someArbitrarySyntax}
${paramChecks}
${inner}
}`;
return result
}
注意import语句后面的语法。这些是编译时导入可用所必需的。示例up起作用。但是,是否有可能获取通过编程生成的现有字符串。。。e、 函数getString{return'abcdef'}并将其转换为语法,我基本上希望将一些参数传递给库,让库返回字符串,然后插入该字符串,而不是在当前时间。如果它是您的库,并且您没有在任何其他上下文中使用它,那么您可以让它返回语法模板而不是字符串。
