Python (re)

CPython stdlib `re`. Unicode-aware `\w` and `\d` by default.

GOSupported

Go (RE2)

Linear-time matching. No backreferences or lookarounds.

Pattern

regexengine-agnostic
^\.[^.\s/\\][^/\\]*$

Raw source: ^\.[^.\s/\\][^/\\]*$

How it works

`^\.` requires leading dot. `[^.\s/\\]` requires the next character to not be another dot, whitespace, or slash. `[^/\\]*$` allows any additional non-slash characters.
