Escaping backslashes in CI output

Continua CI Bugs

I have problem with outputting network path as log messages and as comments.

\\serverHostname\data\output\master
Outputted to comment or log message look like this → \serverHostname\data\output\master

\\serverHostname\data\output\release\branch
Outputted to comment or log message look like this → \serverHostname\data\output elease\branch

So 2 backslashes are escaped to one, and \r is escaped to return carriage ?

When I escape \\ with \\\\, the output is \\\\ :smiley:
When I escape \r with \\r, the output is \release :smiley:

Hi Michal,

What action or code are you using to output the log messages and comments?

No escaping is required when using the Log Entry action:

From your previous posts, I’m guessing that you are outputting the log messages and comments from a Powershell script. In this case, you do have to escape all backslashes. e.g.

write-Host "@@continua[message value='\\\\serverHostname\\data\\output\\master' status='information']"
write-Host "@@continua[message value='\\\\serverHostname\\data\\output\\release\\branch' status='information']"

write-Host "@@continua[addBuildComment comment='\\\\serverHostname\\data\\output\\master']"
write-Host "@@continua[addBuildComment comment='\\\\serverHostname\\data\\output\\release\\branch']"

This outputs the following to the log:

And the following comments:
