Question

I have a text with variables like [abcderere].
In order to detect those variables i decided to create the following regex :

(\[.+?\])

It does work with string like [azerty][qwerty] but I want my regex to also detect String like [[azerty] because it matches the pattern but it doesn’t work

Answer 1

Perhaps this will help:

(\[[^\[\]]+\])
^ ^^     ^  ^^
| ||     |  ||
| |+-----+  ||
| +---------+|
+------------+

Given a string such as [[azerty], it will skip the first square bracket and match [azerty]. For the string [[azerty][foobar]] it will match [azerty] and [foobar]. Demo here.
