Replace spaces in text with chosen character (useful when processing queries containing spaces – they are often turned into “+” or “_”).

>>> replaceSpaces '_' "hi   there"
"hi___there"

Convert the 1st character of a string to upper case.

This function is dumber than it could've been; when the 1st character doesn't have a single-character uppercase form (like “ß”), it is left intact instead of being converted (“Ss” in the case of “ß”). This is good, however; for instance, if the “proper” capitalisation rule was applied to e.g. Wikipedia links, a link to the article on “ß” would've been rendered as “Ss”, which is a redirect to “Schutzstaffel”.

Strip given prefix from a string, or do nothing if the string doesn't have given prefix.

This function is case-insensitive.

>>> tryStripPrefixCI "FOO" "FooBAR"
"BAR"

>>> tryStripPrefixCI "foo" "quux"
"quux"

Strip given prefix from a string.

This function is case-insensitive.

>>> stripPrefixCI "FOO" "FooBAR"
Just "BAR"

>>> stripPrefixCI "foo" "quux"
Nothing

Choose the 2nd value if the 1st is empty (equal to mempty).

A printf-like function which fully supports Text as an input and output format and which uses {} instead of % to indicate placeholders. If you use it, don't forget to enable OverloadedStrings.

This is a lightweight alternative to something like the text-format package, and it's closer to printf and simpler to use.
