Multiline String Support

[ephos]

Hello, I saw another issue open and then closed by the person that opened it regarding this with no other comments.

Current state:

something:
  name: test
  key:
  - '-----BEGIN PGP MESSAGE-----'
  - 'Version: GnuPG v2.0.22 (GNU/Linux)'
  - 'blah'
  - 'blah'
  - 'blah'
  - '-----END PGP MESSAGE-----'

Desired state:

something:
  name: test
  key: |
    -----BEGIN PGP MESSAGE-----
    Version: GnuPG v2.0.22 (GNU/Linux)
    blah
    blah
    blah
    -----END PGP MESSAGE-----

Apologies if it is something I am doing, I tried various options but couldn't seem to get it to handle the multiline string.

Hi @ephos,

First of all, my apologies for not getting back to you sooner.

Secondly, I tried this:

PS /home/gabriel> $data = @'
>> something:
>>   name: test
>>   key: |
>>     -----BEGIN PGP MESSAGE-----
>>     Version: GnuPG v2.0.22 (GNU/Linux)
>>     blah
>>     blah
>>     blah
>>     -----END PGP MESSAGE-----
>> '@
PS /home/gabriel> $x = ConvertFrom-Yaml $data
PS /home/gabriel> $x["something"]["key"]
-----BEGIN PGP MESSAGE-----
Version: GnuPG v2.0.22 (GNU/Linux)
blah                              
blah                                     
blah       
-----END PGP MESSAGE-----
           
PS /home/gabriel> ConvertTo-Yaml $x          
something:             
  key: |        
    -----BEGIN PGP MESSAGE-----
    Version: GnuPG v2.0.22 (GNU/Linux)
    blah
    blah
    blah
    -----END PGP MESSAGE-----
  name: test

Would you mind pasting an example of what you tried?

Sorry I also just saw this reply! I just tried it out and it looks like it may work, I am going to try it tomorrow to see if it fixes what I saw when I originally opened the issue. Below is what I tried and it seems to honor the multi line string.

$yaml = @"
something:
  name: test
  key: |
    -----BEGIN PGP MESSAGE-----
    Version: GnuPG v2.0.22 (GNU/Linux)
    blah
    blah
    blah
    -----END PGP MESSAGE-----
"@

# Deserialize
$object = $yaml | ConvertFrom-Yaml

# Updated value
$newPGPMsg = @"
-----BEGIN PGP MESSAGE-----
Version: GnuPG v2.0.22 (GNU/Linux)
foo
foo
foo
-----END PGP MESSAGE-----
"@

# Update the value
$object.something.key = $newPGPMsg
$object.something.key 

# Serialize back to YAML
$object | ConvertTo-Yaml
