Introduction

Create Regular Expressions easily with code. By using a simple, English-like syntax, you can create any expression you want without actually knowing Regular Expressions. Use the Regcode API to match against a string directly or convert it to Regex.

You can try it out yourself here.

Regcode Example

To show the simplicity of Regcode, here is a basic example of what you could do without any effort. As well as the much more advanced regex it will generate. This is regcode for a simple URL.

hasBefore(https://) normal(www.) [character]{any} normal(.com)[or]normal(.net)

By running this using the Regcode API, you will generate a fully working Regex code that you can use anywhere.

/(?<=https:\/\/)www\.[A-Za-z\u00C0-\u017F]*(?:\.com|\.net)/

This can then be used to match with a string. For example, this string.

The url is https://www.regcodejs.com, here you go!

By running the regex (or regcode) statement on this string, it will return all matches it has found, resulting in the line below.

www.regcodejs.com

API Example

This exact example can be demonstrated using the Regcode API.

const regCode = new RegCode();
const code = "hasBefore(https://) normal(www.) [character]{any} normal(.com)[or]normal(.net)";
const sentenceToMatch = "The url is https://www.regcodejs.com, here you go!";

// look for matches
const match = regCode.match(code, sentenceToMatch);

// or convert to regex and match the normal way
const regex = regCode.convert(code);
const match = sentenceToMatch.match(regex);

Explanation

The example above is a very simple one. The convert method will return a regex statement that you can use any way you like. If you only want to find a match directly, you can do that using the match method.

The match for this particular regcode looks like this.

hasBefore(https://) - the match has to have https:// before, but it will not be included in the match.
normal(www.) - will look for www. in a row.
[character]{any} - will look for any international character, 0 or any times.
normal(.com)[or]normal(.net) - will match either .com or .net.
