Development Tips

There files need to be modified while add a new site:

main.go: add entrance url
links.go -> SetLinks(): add case about target urls feature regex, eg: if url must have about, param 2 is .*?about.*
site/newsite: copy files from sibling folder, then develop and pass the test.
post.go -> TreatPost(): add case for new site domain.
