I always have an interest in script languages like Bash, to provide an OS-wide ability to run tasks. Bash was my choice, and it works kinda well on Linux. But when I turn to Windows, which I use the most often, it sucks. I never want to use WSL to run some toy scripts, and Bash emulators are just slow and unsatisfying.
Python is great but still kind of huge, especially when I just want some text manipulations in the terminal.
Perl is widely used in my recent project in my job. It seems to be a better Bash and is very appealing to me. Also, Strawberry Perl (Perl environment on Windows) works just like how Perl on Linux does. So I speedrun Perl tutorials these two days and wrote this tiny program as a practice. It's so fun to have powerful regex support and explore sigil usages, while it's just so weird to write a class/package in Perl.
And oh, I'm learning piano from scratch. So, key signatures!
By default, it runs on Simplified Chinese.
./test.pl [-gbk] [-zh] [-en]
-gbk use gbk encoding instead of utf8 for output
(usually you never need this)
ps. Simplified Chinese Windows sucks.
-zh set language to Simplified Chinese
-en set language to English
On Windows, you may need to do:
perl -CSDA ./test.pl [other_arguments]
to run correctly.
When in the test, submit anything invalid to show the help message.
