RegEx: Modify text between sh. and ( to lowercase

Michael Wenzel · Jan 25, 2019, 7:54 PM

Hi,
I need help again in term of using regular expression for filtering.

I have a lot of text to modify.
The part of the text I have to modify to lower case after sh. and before (.

Here are two examples:
sh.Wetter.Darksky.currently.windSpeed.beaufort_string(“Windstille”)
sh.Tankstellen.Metro_Eibach.diesel(element[‘diesel’])

to be be converted to
sh.wetter.darksky.currently.windSpeed.beaufort_string(“Windstille”)
sh.tankstellen.metro_eibach.diesel(element[‘diesel’])

Thank you!

@Michael-Wenzel

you can easily do this by using a regex search/replace in notepad++

find what: (sh.)(.*?)(\()
replace with: $1\L$2$3
search mode: regular expression

gives you:

sh.wetter.darksky.currently.windspeed.beaufort_string("Windstille")
sh.tankstellen.metro_eibach.diesel(element['diesel'])

as result

@Michael-Wenzel

you’re welcome.

here’s a little explanation to get you started using regex so that you can easily adapt them for your needs:

search what:

(s.h):
the first is the beginning text that you are searching for
the brackets ( and ) define a string buffer, which will be available at the replace as variable $1.
every time you enclose another section in brackets, you will create a new string buffer variable $2 and so on.

(.*?):
this states that the text in between your beginning and the end can be anything with any length.
it’s content will be reflected as $2

(\():
this marks your end search character ( where you want to stop converting to lower case.
note: this looks weird, but it’s basically a ( bracket in between two brackets.
to make sure it is interpreted as text and not as a bracket that opens another buffer, it has to be “escaped” marked with a preceeding \.
it’s easier to read if some spaces are inserted: ( \( )

replace with:

$1\L$2$3

this needs almost no further information.
the string buffer variables $1 $2 and $2 are put together without spaces, and \L before $2 converts the second string variable to lower case

i’d call it a typo …
you’re not in a good mood today, am i right ?

@Meta-Chuh

Nono…mood is fine. You seem like a humorous guy, with all the emojis, thought you’d like the “facepalm” thing. Sorry. Certainly didn’t intend to offend.

@Alan-Kilborn
ahhh …
i only know text based face palm as:

(－‸ლ)

😂

glad you’re in a good mood, i was worried a bit, and i tend to ask freely.

OOKKKAAAYY - everybody seems to know what facepalms means except … MEEEE. :-)
What does it mean??

@Eko-palypse

I think a possible explanation for facepalm is “I can’t believe I did that”. In the usage above, making a mistake in the regex you are trying to explain the meaning of yields that reaction.
