[BUG] Leading zeros are stripped from template filename when starting with tt0xxxx

[ghdoca]

Describe the bug
When creating a file from a template and the filename is an imdbId like tt0780504 the leading zero is deleted and the filename is tt780504.
This happens when the file name format is off and the input is manual or the file name format is on and the input is from a variable.
If the variable is prefixed with "" it does not work as obviously this is not allowed in a filename.

To Reproduce
Steps to reproduce the behavior in Obsidian:

1. Open Obsidian and create a macro and then add a template
2. Run the macro and it will ask for a filenname
3. Input tt0780504 and filename is tt780504

Expected behavior
It should not strip the leading zero.

This happend because the file already existed but the trigger is not on?

So is it actually a problem of the trigger? Shouldn't it ask what to to when the file already exists and the button is off?

Hey! Thanks for reporting this. The bug has been fixed and merged.

If you want QuickAdd to create a new file when the target name already exists, set your Template choice to:
If the target file already exists -> Create another file

Then choose one of these naming behaviors:

• Increment trailing number
  Example: tt0780504.md -> tt0780505.md
• Append duplicate suffix
  Example: tt0780504.md -> tt0780504 (1).md

The specific issue you hit was with Increment trailing number, where leading zeros could be stripped. That now works correctly.

The fix will be included in the next release. If you still see incorrect numbering after updating, please reply with your exact Template choice settings and an example filename.
