[Fix] #6

[Kristinita]

1. Behavior before pull request

I create a new Markdown file → Ctrl+Shift+P (⌘⇧p for Mac) → Pelican: Insert Metadata → metadata insert:

Ctrl+Shift+P (⌘⇧p for Mac) → Pelican: Update Article Date → Date metadata variable update:

2. Behavior after pull request

I add a new metadata variable Modified.

I create a new Markdown file → Ctrl+Shift+P (⌘⇧p for Mac) → Pelican: Insert Metadata → metadata with new Modified variable insert, Modified value = Date value:

Ctrl+Shift+P (⌘⇧p for Mac) → Pelican: Update Modified → Modified variable update, Date variable stay constantly.

3. Argumentation

See @jachin arguments. Date variable — time, when we create article or page. Modified variable — last update time article or page. We must update Modified, not Date. See File Metadata section in official documentation.

4. Testing environment

Operating system and version:
Windows 10 Enterprise LTSB 64-bit EN
Sublime Text:
Build 3126
Syntax:
Markdown

5. Notes

1. I'm sorry, I don't know reStructuredText — I don't know, how my changes will work in rst files.
2. This pull request don't solve [Feature request] Modified setting update on save #30 issue. Modified variable doesn't update by save.

Thanks.

Sorry, I don't see, that for Sublime Text 3 you have a specific branch.
