NAME
====
Text::MathematicalCase - convert to/from mathematical case
SYNOPSIS
========
```raku
use Text::MathematicalCase; # just mc
say mc "Hello World" :serif:bold; # 𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝
use Text::MathematicalCase :all; # mc lc uc adverbs
say uc "𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝"; # 𝐇𝐄𝐋𝐋𝐎 𝐖𝐎𝐑𝐋𝐃
```
DESCRIPTION
===========
Text::MathematicalCase is module that exports an `mc` subroutine that implements converting to/from "mathematical case". Just like you can have UPPERCASE or lowercase, you can also have 𝐦𝐚𝐭𝐡𝐞𝐦𝐚𝐭𝐢𝐜𝐚𝐥 𝐜𝐚𝐬𝐞.
"Mathematical case" is basically text expressed in the alphanumeric symbols of the [Mathematical Alphanumeric Symbols](https://en.wikipedia.org/wiki/Mathematical_Alphanumeric_Symbols) unicode block. In it, several styles are supported:
- serif: serif, 𝐬𝐞𝐫𝐢𝐟 𝐛𝐨𝐥𝐝, 𝑠𝑒𝑟𝑖𝑓 𝑖𝑡𝑎𝑙𝑖𝑐, 𝒔𝒆𝒓𝒊𝒇 𝒃𝒐𝒍𝒅 𝒊𝒕𝒂𝒍𝒊𝒄
- sans-serif: 𝗌𝖺𝗇𝗌-𝗌𝖾𝗋𝗂𝖿, 𝘀𝗮𝗻𝘀-𝘀𝗲𝗿𝗶𝗳 𝗯𝗼𝗹𝗱, 𝘴𝘢𝘯𝘴-𝘴𝘦𝘳𝘪𝘧 𝘪𝘵𝘢𝘭𝘪𝘤, 𝙨𝙖𝙣𝙨-𝙨𝙚𝙧𝙞𝙛 𝙗𝙤𝙡𝙙 𝙞𝙩𝙖𝙡𝙞𝙘
- script: 𝓈𝒸𝓇𝒾𝓅𝓉, 𝓼𝓬𝓻𝓲𝓹𝓽 𝓫𝓸𝓵𝓭
- fraktur: 𝔣𝔯𝔞𝔨𝔱𝔲𝔯, 𝖋𝖗𝖆𝖐𝖙𝖚𝖗 𝖇𝖔𝖑𝖉
- monospace: 𝚖𝚘𝚗𝚘𝚜𝚙𝚊𝚌𝚎
- double-struck: 𝕕𝕠𝕦𝕓𝕝𝕖-𝕤𝕥𝕣𝕦𝕔𝕜
It optionally also exports an `lc` and/or a `uc` subroutine (that perform the same function as the standard `lc` and `uc` subroutines, but are aware of mathematical case characters). And it optionally exports an `adverbs` subroutine that lists all the possible combinations of adverbs that can be passed on to the `mc` subroutine.
This distribution also installs a `mc` script for easy access to the mathematical case functionality.
SUBROUTINES
===========
mc
--
say mc "Hello World" :serif:bold; # 𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝
Convert a string to mathematical case with the given adverbs.
lc
--
use Text::MathematicalCase ;
say lc "𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝"; # 𝐡𝐞𝐥𝐥𝐨 𝐰𝐨𝐫𝐥𝐝
Convert a string to lowercase taking mathematical case into account as well.
uc
--
use Text::MathematicalCase ;
say uc "𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝"; # 𝐇𝐄𝐋𝐋𝐎 𝐖𝐎𝐑𝐋𝐃
Convert a string to uppercase taking mathematical case into account as well.
adverbs
-------
use Text::MathematicalCase ;
.say for adverbs;
# :double-struck
# :fraktur
# :fraktur:bold
# :monospace
# :sans-serif
# :sans-serif:bold
# :sans-serif:bold:italic
# :sans-serif:italic
# :script
# :script:bold
# :serif
# :serif:bold
# :serif:bold:italic
# :serif:italic
SCRIPTS
=======
mc
--
$ mc "Hello World" --double-struck
ℍ𝕖𝕝𝕝𝕠 𝕎𝕠𝕣𝕝𝕕
$ mc --double-struck < file-with-text
ℂ𝕠𝕟𝕥𝕖𝕟𝕥 𝕠𝕗 𝕗𝕚𝕝𝕖-𝕨𝕚𝕥𝕙-𝕥𝕖𝕩𝕥
The `mc` script either takes a string, or reads from `STDIN` and performs the mathematical case transformation as indicated by its named arguments.
