Regular Expressions

A regular expression is a sequence of characters that specifies a search pattern in text. Usually such patterns are used by string-searching algorithms for “find” or “find and replace” operations on strings, or for input validation.

VS Code

To transform the obsidian markdown link [what-is-blockchain](./what-is-blockchain/what-is-blockchain) into [[what-is-blockchain]] using a regex in VSCode, you can use the following pattern:

• Find: regex \[([^\]]+)\]\(\./\1/\1\)

• Replace with: regex \[\[$1\]\]

Explanation:

\[([^\]]+)\]: Matches the text inside the square brackets [ ]. The ([^]]+) captures the content between the brackets.

\(\./\1/\1\): Matches the link (./something/something) where something is the same text captured in the first part.
