Skip to contents

Migrate odin code. This function takes a path to existing odin code and writes out migrated code to a new file. It is possible that no code will be migrated, in which case the written contents will be identical to those read.

Usage

odin_migrate(path, dest)

Arguments

path

Path of the odin code to read

dest

Path of the destination code. It can be the same as dest, in which case the file will be overwritten.

Value

Nothing; called for side effects only

Examples

# A file 'path' contains odin code using old features:
writeLines(readLines(path))
#> initial(x) <- 0
#> deriv(x) <- x * r
#> r <- user()

# Migrate this file in place (by overwriting)
odin_migrate(path, path)
#>  Migrating 1 statement
#>  Wrote '/tmp/RtmpaB1x3n/file179262c476a3.R'

writeLines(readLines(path))
#> initial(x) <- 0
#> deriv(x) <- x * r
#> r <- parameter()
