Rendering SLS fails due to "\" in Windows

[varun bhatnagar]

Hi,

I have a saltstack (Carbon version) setup with Windows minions. I am trying to get the binary path of a service and this is how my state file looks:

# cat test.sls

{% set test_var = salt.service.info("SDRSVC") %}

run_command:

  module.run:

    - name: test.echo

    - text: "{{ test_var['BinaryPath'] }}"

WhenI execute it I am getting an error saying found unknown escape character 'W'; line 6

It considers \Windows as an escape chaaracter.

# salt -t 60 '192.168.133.129' state.apply test

192.168.133.129:

    Data failed to compile:

----------

    Rendering SLS 'base:test' failed: found unknown escape character 'W'; line 6

---

run_command:

  module.run:

    - name: test.echo

    - text: "C:\Windows\system32\svchost.exe -k SDRSVC"    <======================

---

Any suggestions on how to fix this?

Backslash (\) is escaping character in YAML when the string enclosed by double quote “

http://www.yaml.org/spec/1.2/spec.html#id2776092

In your SLS, YAML will understand that \W is escaping W character as it has some special meaning.

So solutions are:

- Enclosed your path by single quote ‘{{ ABC }}’, then \ will not be “thought” as escaping

- Or, keep the double quotes but replace all backslash \ with double backslashes -> \\

"C:\\Windows\\system32\\svchost.exe -k SDRSVC”

Hello Viet,

Thanks!
