This is moderately messy. Process was principally: * xargs rg --files-with-matches '^use Title;' | grep 'php$' | \ xargs -P 1 -n 1 sed -i -z 's/use Title;/use MediaWiki\\Title\\Title;/1' * rg --files-without-match 'MediaWiki\\Title\\Title;' . | grep 'php$' | \ xargs rg --files-with-matches 'Title\b' | \ xargs -P 1 -n 1 sed -i -z 's/\nuse /\nuse MediaWiki\\Title\\Title;\nuse /1' * composer fix Then manual fix-ups for a few files that don't have any use statements.
