Support creating hard links (in additional to symlinks) #301
Description
With for example, gitman.yml:
location: vendor/gitman
sources:
- repo: https://github.com/jacebrowning/gitman.git
name: gitman
rev: main
type: git
links:
- source: doc
target: vendor/doc/gitman
And .gitignore:
vendor/gitman
vendor/doc/gitman will be a symlink, and content in vendor/gitman will be ignored.
For my project I want to keep copies of the libraries I use, and since git does not follow symlinks the approach above does not work.
I could of course remove the entry in .gitignore, but then I get a lot of unneeded resources.
Hard links seem to be the way to resolve this. Suggested implementation, gitman.yml:
location: vendor/gitman
sources:
- repo: https://github.com/jacebrowning/gitman.git
name: gitman
rev: main
type: git
hardlinks:
- source: doc
target: vendor/doc/gitman
vendor/doc/gitman would be a regular directory, each file inside would be a hardlink, and any nesting directory would be recreated with the same name as a directory (not symlink). Like a copy (cp -r) but the files are hard linked instead of copies.
Of course hard links has some limitations, has to be on same file system for instance. So an option to fallback to a copy would perhaps required.
