In nextflow I would love to see my script in its final form, meaning after nextflow has replaced $myfavouritevariable ecetera ... is that possible? Something like:
process myproc {
...
script:
"""
# my bash script here
"""
afterEvaluation:
print final script to file
}
For each process execution, Nextflow generates a .command.sh file in the working directory (i.e. ./work) that contains the final "fully rendered" command with all substitutions applied. For example:
process myproc {
tag "$name"
input:
val name
script:
"""
echo "Hello ${name}"
"""
}
workflow {
names = Channel.of('Mark', 'Luke', 'John', 'Matthew')
myproc( names )
}
Results:
$ nextflow run main.nf -ansi-log false
