This is a very simple little tool to replace placeholders in templates by your desired name. It replaces all casings of a given string by the respective casings of your string.
Example invocation:
template-filler --source path/to/template --destination path/to/new/project --find FooBar --replace HomelessShelter
This replaces:
FooBar -> HomelessShelter
fooBar -> homelessShelter
foo-bar -> homeless-shelter
foo_bar -> homeless_shelter
FOO_BAR -> HOMELESS_SHELTER
foo bar -> homeless shelter
Foo Bar -> Homeless Shelter
foo.bar -> homeless.shelter
Foo.Bar -> Homeless.Shelter
foo/bar -> homeless/shelter
Foo/Bar -> Homeless/Shelter
If something goes wrong, you can find a backup of your files at ~/.local/share/template.
