I'm trying to replace uppercase letters with corresponding lowercase letters using regex. So that

EarTH:   1,
MerCury: 0.2408467,
venuS:   0.61519726,

becomes

earth:   1,
mercury: 0.2408467,
venus:   0.61519726,

in Sublime Text. How can I downcase letters only in words that contain both lower and uppercase letters? So that it affects venUs and not VENUS.

Regular expression

Find:\w+

Replace:\L$0

Sublime Text uses the Perl Compatible Regular Expressions (PCRE) engine from the Boost library to power regular expressions in search panels.

\L Converts everything up to lowercase

$0 Capture groups

In BBEdit works this (ex.: changing the ID values to lowercase):

Search any value: <a id="(?P<x>.*?)"></a> Replace with the same in lowercase: <a id="\L\P<x>\E"></a>

Was: <a id="VALUE"></a> Became: <a id="value"></a>

  • FIND: (\u)
  • REPLACE: \L$1$2

Operation confirmed in Notepad++.
Do not forget to check the "Match case" box.
