Is the language name case sensitive for syntax highlighting?

Question

I often use the syntax-highlighting feature of Stack Exchange in order to make my code easier to read.

```lang-python
for k in range(0, 10):
    print(k)
```

for k in range(0, 10):
    print(k)

There are many different ways to capitalize a string such as lang-python:

• Lang-Python
• LANG-Python
• lang-PYTHON

Is the language tag case sensitive for syntax highlighting? I often mistype it and write something like "lang-Pythn" but no error messages are displayed.

Answer 1

Tl;dr lang- must be lowercase, capitalization on the language name can be anything

Let's try it out in the formatting sandbox:

All lowercase:

```lang-python
for i in range(10):
    if i % 2:
        print(i)
```

for i in range(10):
    if i % 2:
        print(i)

All caps:

```LANG-PYTHON
for i in range(10):
    if i % 2:
        print(i)
```

for i in range(10):
    if i % 2:
        print(i)

Language name all caps:

```lang-PYTHON
for i in range(10):
    if i % 2:
        print(i)
```

for i in range(10):
    if i % 2:
        print(i)

All mixed caps:

```LaNg-PyThOn
for i in range(10):
    if i % 2:
        print(i)
```

for i in range(10):
    if i % 2:
        print(i)

Language name mixed caps:

```lang-PyThOn
for i in range(10):
    if i % 2:
        print(i)
```

for i in range(10):
    if i % 2:
        print(i)
