Possible to look for multiple tickers in string?

[Diogovski]

If i use the .includes() function while looping for the object of the tickers i am able to get this
'BTC,ETH,BNB,XRP,ADA,SOL,DOGE,DOT,MATIC,SHIB,T,HI,OG,SHI,D,TH,MAT,A,IC,G,O,DOG,BT'
it returns all the one i need/want, but unfortunately it alsos breaks them appart

[tylim88]

you mean nameLookup?

not possible to transform multiple ticker in one string, but for your case you can do some parsing

import { cryptoSymbol } from "crypto-symbol";

const { nameLookup } = cryptoSymbol({});

const longString =
  "Price analysis 9/14: BTC, ETH, BNB, XRP, ADA, SOL, DOGE, DOT, MATIC, SHIB";

const splitted = longString.split(":");

const tickersArr = splitted[1].split(",");

const getNames = tickersArr.reduce((acc, item, index) => {
  return acc + nameLookup(item) + (index === tickersArr.length - 1 ? "" : ", ");
}, splitted[0] + ": ");

No i only want to return the tickers/symbols A sexta, 16/09/2022, 18:22, Acid Coder ***@***.***> escreveu:

[tylim88]

can you tell me
what is your input?
what is your expected output?

[Diogovski]

my input is different phrases, some only have bitcoin on it, others have other coins on it,
the expected output is the symbols of the coins mentioned on each phrase

[Diogovski]

Current input/output

expected output: only the symbols withput those with only 1,2 char...

[Diogovski]

currently using this to get the tickers , since using the getsymbol function doesnt work when trying to get multiple symbols.

[tylim88]

can you post the raw text for this one?

Current input/output

expected output: only the symbols withput those with only 1,2 char...

I will see what I can do tomorrow, bed time now

thx, its looking better now, i added something so it removes duplicates from the arrays ( mainly BTC ), now gonna try to figure out how to remove those that aren't actually referred as symbols but words

[tylim88]

some coin symbol are English word, you can add a list to filter it out

import { cryptoSymbol } from "crypto-symbol";

const { symbolLookup, nameLookup } = cryptoSymbol({});

const titleArr = [
  " Bitcoin exchange inflows see biggest one-day spike since March 2020 ",
  " Possession of Bitcoin still legal in China despite the ban, lawyer says ",
  " El Salvador's pro-Bitcoin president Nayib Bukele announces reelection bid ",
  " Celsius requests permission to sell off its stablecoins ",
  " Bitcoin price threatens $19.6K as Ray Dalio predicts 30% stocks crash ",
  " The Ethereum Merge to proof-of-stake is complete — What’s next? | Interview with Dr. Julian Hosp ",
  " Bitcoin price loses $20K, ETH price drops 8% after 'monumental' Ethereum Merge ",
  " Crypto for foreign trade: What do we know about Iran’s new strategy ",
  " Norwegian town wants 'noisy' Bitcoin miner out, CEO responds ",
  " Michael Saylor slams 'misinformation' about Bitcoin’s energy use ",
  " Price analysis 9/14: BTC, ETH, BNB, XRP, ADA, SOL, DOGE, DOT, MATIC, SHIB ",
  " Analyst on $17.6K BTC price bottom: Bitcoin 'not there yet' ",
  " BTC price clings to $20K as US stocks lose the equivalent of 4 Bitcoin market caps ",
  " Bitcoin is the perfect settlement layer to build apps on top of: Hiro CEO ",
  " Bitcoin margin long-to-short ratio at Bitfinex reaches the highest level ever "
];

const englishWords = ["layer", "ever", "build", "top", "caps"];

const answ = titleArr.map((title) => {
  const arr: string[] = [];
  const exist: Record<string, boolean> = {};
  title.split(" ").forEach((word) => {
    const isEnglishWord = englishWords.some((eword) => {
      return word.toLowerCase().includes(eword);
    });
    if (!isEnglishWord) {
      const found =
        symbolLookup(word) ||
        symbolLookup(nameLookup(word) || "hsuadhiudhsudhahdi");

      const isDuplicated = exist[`${found}`];
      exist[`${found}`] = true;
      !isDuplicated && found && arr.push(found);
    }
  });
  return arr;
});

console.log(answ);

there is problem with matching text like bitcoin's, because this is a lookup library, it can filter out unnecessary character but it cant match the closest text

example:
bitcoin' --> bitcoin --> found!
bitcoin's --> bitcoins --> not found!

[tylim88]

partially solved by using regex expression

import { cryptoSymbol } from "crypto-symbol";

const { symbolLookup, nameLookup } = cryptoSymbol({});

const titleArr = [
  " Bitcoin exchange inflows see biggest one-day spike since March 2020 ",
  " Possession of Bitcoin still legal in China despite the ban, lawyer says ",
  " El Salvador's pro-Bitcoin president Nayib Bukele announces reelection bid ",
  " Celsius requests permission to sell off its stablecoins ",
  " Bitcoin price threatens $19.6K as Ray Dalio predicts 30% stocks crash ",
  " The Ethereum Merge to proof-of-stake is complete — What’s next? | Interview with Dr. Julian Hosp ",
  " Bitcoin price loses $20K, ETH price drops 8% after 'monumental' Ethereum Merge ",
  " Crypto for foreign trade: What do we know about Iran’s new strategy ",
  " Norwegian town wants 'noisy' Bitcoin miner out, CEO responds ",
  " Michael Saylor slams 'misinformation' about Bitcoin’s energy use ",
  " Price analysis 9/14: BTC, ETH, BNB, XRP, ADA, SOL, DOGE, DOT, MATIC, SHIB ",
  " Analyst on $17.6K BTC price bottom: Bitcoin 'not there yet' ",
  " BTC price clings to $20K as US stocks lose the equivalent of 4 Bitcoin market caps ",
  " Bitcoin is the perfect settlement layer to build apps on top of: Hiro CEO ",
  " Bitcoin margin long-to-short ratio at Bitfinex reaches the highest level ever "
];

const englishWords = ["layer", "ever", "build", "top", "caps"];

const answ = titleArr.map((title) => {
  const arr: string[] = [];
  const exist: Record<string, boolean> = {};
  title.split(/[,.’'\s]/).forEach((word) => {
    const isEnglishWord = englishWords.some((eword) => {
      return word.toLowerCase().includes(eword);
    });
    if (!isEnglishWord) {
      const found =
        symbolLookup(word) ||
        symbolLookup(nameLookup(word) || "hsuadhiudhsudhahdi");

      const isDuplicated = exist[`${found}`];
      exist[`${found}`] = true;
      !isDuplicated && found && arr.push(found);
    }
  });
  return arr;
});

now it is able to match bitcoin's but still not able to match bitcoins, I will put this on roadmap
