Cannot re-parse multi-line strings

[j-shilling]

I'm running into an issue trying to encode multi-line strings and then parse them again. For example, when I run:

(->  "
build_the_package:
  stage: build
  script: |-
    if [ -z \"${CUSTOM}\" ]; then
      ./mvnw package
    fi
"
  (yaml-parse-string :object-key-type 'string)
  yaml-encode
  yaml-parse-string)

I get a cryptic message "Unable to parse YAML stream. Parser finished before end of input 21/99." This seems to be because yaml-enocde does not encode multi-line strings with the |- syntax but instead escapes all the new lines:

(->  "
build_the_package:
  stage: build
  script: |-
    if [ -z \"${CUSTOM}\" ]; then
      ./mvnw package
    fi
"
  (yaml-parse-string :object-key-type 'string)
  yaml-encode)
;;=> "
;;=>build_the_package: 
;;=>  script: \"if [ -z \\\"${CUSTOM}\\\" ]; then\\n  ./mvnw package\\nfi\"
;;=>  stage: build"

Thanks for bringing this up! There was definitely a bug in the way that escape characters were being handled. I mistakenly put the parsing rule as ?\\ + ?\n as opposed to ?\\ + ?n. With this change in the round trip should work. I apologize for the cryptic error message though. I'll open a ticket for improving error messages of parsing errors.

Thanks @zkry ! My tests are now working--or at least, all the problems are on my end now.
