Hi, I am currently trying to include the line:

sed -i 's/DEFINER=[^*]*\*/\*/g' dump.sql into my script: contents: """ section, but am getting an error:

ERROR system | failed to load plan: unknown escape sequence:

Any ideas on how I can modify the sed line so that Cue doesn't complain please?

Thanks

Hi! 👋
guessing this is what you need :). https://cuelang.org/docs/tutorials/tour/types/stringraw/

script: contents: #"""

  sed -i 's/DEFINER=[^*]*\*/\*/g' dump.sql

CUE
"Raw" Strings

CUE does not support raw strings in the strictest sense. Instead it allows modifying the escape delimiter by requiring an arbitrary number of hash # signs after the backslash by enclosing a string literal in an equal number of hash signs on either end.
This works for normal and interpolated strings. Quotes do not have to be escaped in such strin...

So, are you saying that I just need to prepend a # to my initial """?

prepend to initial and append/"postpend" to final

🙂 So what does the # do then?

It seems to help quite a bit when there are *, #, \and some other problematic chars in the multi-line string. Especially if you need to have the literal sequence \( and don't want it to indicate string interpolation. You just need to adjust how you do interpolation to use same number of hash chars.

#

Here I'll use ### as example:

// The first time you run the hello
// action as `dagger do hello --log-format plain`,
// make sure to run `dagger project update` first,
// so that all required dependencies are available.

package hello

import (
  "dagger.io/dagger"
  "universe.dagger.io/bash"
  "universe.dagger.io/alpine"

)

dagger.#Plan & {
  client: env: GREETING: string
  actions: {
    _alpine: alpine.#Build & {
      packages: bash: _
    }

    // Hello world
    hello: bash.#Run & {
      input: _alpine.output
      script: contents: ###"""
        # this is a comment
        echo 'DEFINER=redactablestuff*DEFINER=redactablestuff*' > dump.sql 
        sed -i 's/DEFINER=[^*]*\*/\*/g' dump.sql
        cat dump.sql
        echo "Hello \###(client.env.GREETING)!"
