Issue
Aim:extract sentences or paragraphs from the given syntax structure. Pick any random word/phrase between “{” & “}” separated by “|” and make one realistic output.
Input:
{Hi|Hello|Hola} @name, Good {Morning|Evening}. {I am|We are} very {glad|hapy) that you came here {to meet us.
Output1: Hi abc Good Morning, I am very glad that you came here to meet us.
Output2: Hola abc Good Evening, I am very happy that you came here to meet us.
Output3: Hello abc Good Morning, We are very glad that you came here to meet us.
function extract([beg, end]) {
const matcher = new RegExp(`${beg}(.*?)${end}`,'gm');
const normalise = (str) => str.slice(beg.length,end.length*-1);
return function(str) {
return str.match(matcher).map(normalise);
}
}
var str = "{Hi|Hello|Hola} @name, Good {Morning|Evening}. {I am|We are} very {glad|hapy) that you came here {to meet us."
const stringExtractor = extract(['{','}']);
const stuffIneed = stringExtractor(str)I have extract the words between {} in array and now trying to compare and replace them
Solution
One solution is by using regular expressions
Here is a code snippet
I isolated the {...} parts, then split them by |, used random and then replaced the original {...} part with the random element
let t = '{Hi|Hello|Hola} @name, Good {Morning|Evening}. {I am|We are} very {glad|hapy} that you came here to meet us.'
let matches = t.match(/{([A-Z ](\|*))*}/gi)
for (const match of matches) {
let splt = match.replace('{', '').replace('}', '').split('|')
t = t.replace(match, splt[Math.floor(Math.random() * splt.length)])
}
console.log(t)Second approach using a method
let t = '{Hi|Hello|Hola} @name, Good {Morning|Evening}. {I am|We are} very {glad|hapy} that you came here to meet us.'
function printSentence(sentence) {
let matches = t.match(/{([A-Z ](\|*))*}/gi)
for (const match of matches) {
let splt = match.replace('{', '').replace('}', '').split('|')
sentence = sentence.replace(match, splt[Math.floor(Math.random() * splt.length)])
}
console.log(sentence)
}
printSentence(t)
printSentence(t)
