Now that JSRef<T> is gone, there is no need to have helper traits.
On components/script/*.rs:
# Remove imports.
/^ *use dom::[a-z]+::\{.*Helpers/ {
s/\{(Raw[^L]|[^L][^a])[a-zA-Z]+Helpers, /\{/
s/, (Raw[^L]|[^L][^a])[a-zA-Z]+Helpers([,}])/\2/g
s/\{([a-zA-Z]+)\}/\1/
/\{\}/d
s/::self;$/;/
}
/^ *use dom::[a-z]+::\{?(Raw[^L]|[^L][^a])[a-zA-Z]+Helpers\}?;$/d
On components/script/dom/*.rs:
# Ignore layout things.
/^(pub )?(impl|trait).*Layout.* \{/,/^}$/ { P; D; }
# Delete helpers traits.
/^(pub )?trait ([^L][^ ]|L[^a])[^ ]+Helpers(<'a>)? \{$/,/^\}$/D
# Patch private helpers.
/^impl.*Private.*Helpers/,/^\}$/ {
s/^impl<'a> Private([^L][^ ]|L[^a])[^ ]+Helpers(<'a>)? for &'a ([^ ]+) \{$/impl \3 {/
/^ *(unsafe )?fn .*\(self.*[<&]'a/ {
s/&'a /\&/g
s/<'a, /</g
}
/^ *(unsafe )?fn /s/\(self([,)])/\(\&self\1/
}
# Patch public helpers.
/^impl.*Helpers/,/^\}$/ {
s/^impl(<'a>)? ([^L][^ ]|L[^a])[^ ]+Helpers(<'a>)? for (&'a )?([^ ]+) \{$/impl \5 {/
/^ *(unsafe )?fn .*\(self.*[<&]'a/ {
s/&'a /\&/g
s/<'a, /</g
}
/^ *(unsafe )?fn .*\(&?self[,)]/s/(unsafe )?fn/pub &/
/^ *pub (unsafe )?fn /s/\(self([,)])/\(\&self\1/
}
The few error cases were then fixed by hand.
