# Reads the Miller DSL grammar file and generates Go code.

# This is not run on every build / commit / etc.

# It's intended to be run manually by the developer, as needed when mlr.bnf
|
|
# changes for example.
|

|

# Resulting auto-generated .go files should then be checked into source control.

# With verbose, *.txt files are created with information about LR1 conflicts
|

# etc. Please don't commit them.
|
|
#
|
|
# As of mid-2021 this takes easily 5-10 minutes to run.
