Strugglin with XYEXP

[ploegsteert]

Hello,

First I'd like to thank you for all the great work you did on this tool ! It's amazing.

I'm just having a problem with a shell script containing :

docker ps -a --format '{{.ID}} {{.Names}}'

As you can see, this command contains code that looks exactly like XYEXP. I'd like to espace it or disable macro expression for this particular script. Is it possible ?

Thank you in advance for your answer.

Hi! Thanks for the kind words, and for reporting this!

For an immediate workaround, you can split the opening braces across adjacent quoted strings (POSIX trick, works in most shells):

docker ps -a --format '{''{.ID}} {''{.Names}}'

This prevents xyOps from recognizing the {{ sequences as expressions. The shell joins the quoted strings back together, so Docker receives the original format string: {{.ID}} {{.Names}}.

We're also working on an escape mechanism for the next version, so you can preserve literal templates like these more easily.

I'll update this issue when the feature is available! Should only be a few days. We release 1 - 2 times per week.

Oh, I didn't knew that ! Thanks a lot, it's working great !

We're also working on an escape mechanism for the next version, so you can preserve literal templates like these more easily.

This just shipped in xyOps v1.1.5. You can now include a comment anywhere in your script that includes the symbol XY_NO_EXP and it will disable all macro substitution for that parameter.

Example:

#!/bin/bash
# XY_NO_EXP

docker ps -a --format '{{.ID}} {{.Names}}'

Hope this helps! Cheers!
