Online Lower Case Converter

I want to know how to make whatever the user inputs to ignore case in my method:

public static void findPatient() {    if (myPatientList.getNumPatients() == 0) {        System.out.println("No patient information is stored.");    }    else {        System.out.print("Enter part of the patient name: ");        String name = sc.next();        sc.nextLine();        System.out.print(myPatientList.showPatients(name));    }}

How do I take a string and convert it to lower or upper case in Ruby?

I want to convert strings to lower or upper case in JavaScript in the locale I wanted. I think standard functions like toUpperCase() and toLocaleUpperCase() do not satisfy this need. toLocale functions do not behave as they should.

For example, in Safari 4, Chrome 4 Beta, Firefox 3.5.x on my system it converts strings with Turkish characters incorrectly. The browsers respond to navigator.language as "en-US", "tr", "en-US" respectively. But there is no way to get user's Accept-Lang setting in the browser as far as I could found. Only Chrome gives me "tr" although I have configured every browser Turkish locale preferred. I think these settings only affect HTTP header, but we can't access to these settings via JavaScript.

In the Mozilla documentation it says

The characters within a string are converted to ... while respecting the current locale. For most languages, this will return the same as ...

I think it's valid for Turkish, it doesn't differ it's configured as en or tr. In Turkish it should convert "DİNÇ" to "dinç" and "DINÇ" to "dınç" or vice-versa.

Is there any JavaScript library that satisfies this need? I think it should not only converting correctly in user's locale, but also it should support conversion via a locale parameter. Because developers cannot access to user's configured preferred language.

I have to store value in one Endeca property but in lowercase. Values can be in uppercase or in lowercase in the source file but I have to store it in lowercase in the Endeca property.

Any pointer on how I can proceed will be helpful.

Assume a multi-line text file file in which some lines start with whitespaces.

$ cat filefoo Baz  baz QUX    QUx QuuxBaZ QuxBazaaR

Further assume that I wish to convert all those lines that start with a keyword (e.g. "baz") to lowercase letters, irrespective if (a) that keyword is written in lower- or uppercase letters (or any combination thereof) itself, and (b) that keyword is preceeded by whitespaces.

$ cat file | sought_commandfoo Baz        # not to lowercase (line does not start with keyword)  baz qux      # to lowercase    QUx Quuxbaz qux        # to lowercaseBazaaR         # not to lowercase (line does not start with keyword, but merely with a word containing the keyword)

I believe that awk is the tool to do it, but I am uncertain how to implement the case-insensitivity for the keyword matching.

$ cat file | awk '{ if($1 ~ /^ *baz/) print tolower($0); else print $0}'foo Baz  baz qux    QUx QuuxBaZ Qux       # ERROR HERE: was not replaced, b/c keyword not recognized.BazaaR

EDIT 1:Adding IGNORECASE=1 appears to resolve the case-insensitivity, but now incorrectly converts the last line to lowercase.

$ cat file | awk '{IGNORECASE=1; if($1~/^ *baz/) print tolower($0); else print $0}'foo Baz  baz qux    QUx Quuxbaz quxbazaar       # ERROR HERE: should not be converted to lowercase, as keyword not present (emphasis on word!).
