SCT is a simple tool to extract code destined to students or for correction from a master file.
For the moment only language which use // to comment code are supported.
Given the following master file (demo.scala):
import spark
object MainApp {
//![
def methodToImplement() = someImplementation
//!-
// def methodToImplement() = ???
//!]
//![-
// // TODO: Some instruction given to the students, but missing from the correction.
//!]
def main(args: Array[String]) {
//![
Code only available in the correction, with no alternative for student.
//!-]
}
}Running sct -s demo.scala outputs the following code (comment the part for the correction and uncomment the part for the student):
import spark
object MainApp {
//![
// def methodToImplement() = someImplementation
//!-
def methodToImplement() = ???
//!]
//![-
// TODO: Some instruction given to the students, but missing from the correction.
//!]
def main(args: Array[String]) {
//![
// Code only available in the correction, with no alternative for student.
//!-]
}
}Running sct -os demo.scala outputs the following code (only the part for the student):
import spark
object MainApp {
def methodToImplement() = ???
// TODO: Some instruction given to the students, but missing from the correction.
def main(args: Array[String]) {
}
}Running sct -co demo.scala outputs the following code (only the part for the correction):
import spark
object MainApp {
def methodToImplement() = someImplementation
def main(args: Array[String]) {
Code only available in the correction, with no alternative for student.
}
}If you want to transform every scala file in a directory into its student version, you can use the following command:
fd -e scala -H --ignore-file=<(sct -so .sctignore) -x sh -c "sct -so {} | sponge {}"If you want to copy a transformed hierarchy of files into a new directory, you can use the following command:
DEST_DIR="../student2021"; fd -t f -H --ignore-file=<(sct -so .sctignore) -x sh -c "mkdir -p $DEST_DIR/{//}; sct -so {} > $DEST_DIR/{}"cabal install exe:sct --install-method=copy --overwrite-policy=always --installdir=dist
stack install --local-bin-path=dist
