tern
allows sql scripts reference scripts in sub folders with the syntax{{ template "path/to/script" . }}
.sqlc
does not accept this syntax appears within migration scripts, which means you either gives up the nice organizational feature of tern, or gives up sqlc.By adding a pre-processor func
TransformStatements()
next toRemoveRollbackStatements()
, this PR allows sqlc to fetch content of script files referenced by tern template syntax and replace the syntax lines with the actual sql file content.
