Inconsistency of whether to capitalize a character after numbers among different versions

[msmx-mnakagawa]

From the following style, this package generates different classnames based on its version.

.table--5columns-10rows {
  background: red;
}

Some versions generate table5Columns10Rows, and others do table5columns10rows.

Depending on its version, whether to capitalize c in 5columns and r in 10rows, which are characters after numbers, differs.

Minimal reproducible example

https://github.com/msmx-mnakagawa/typed-scss-modules-char-after-number-minimal-reproduction

Steps to Reproduce (for bugs)

1. Clone the example repository.
2. Install dependencies.

   $ yarn
   

3. Confirm the version of typed-scss-modules is 6.3.0.
4. Execute the transform npm script, which generates a type definition file as target.scss.d.ts from target.scss.

   $ yarn transform
   

5. Confirm the command generated a capitalized classname as table5Columns10Rows in the target.scss.d.ts.
6. Install the typed-scss-modules@8.1.1, which would be the latest version for now, instead of the current version.

   $ yarn add -D [email protected]
   

7. Execute the transform again.

   $ yarn transform
   

8. Confirm the command generated a non-capitalized classname as table5columns10rows.

Expected Behavior

• Clarify which behavior is correct.
• Align behaviors among versions.

Context

IMO, it would be better to align to capitalize.

This is because the latest version of postcss-modules, on which Vite depends, generates a capitalized classname at a runtime.

We can confirm that to do the following steps after the last step of Steps to Reproduce section.

9. Confirm the version of postcss-modules installed with [email protected] is 6.0.1, which would be the latest version for now.
10. Execute the postcss-modules npm script, which consoles a pair of key/value of the classname.

    $ yarn postcss-modules
    

11. Confirm the command shows a capitalized key like the following in your console.

    { table5Columns10Rows: '_table--5columns-10rows_fs1ss_1' }
