Escape chars printed raw in partial console output since 0.7.0

Escape chars printed raw in partial console output since 0.7.0 (works ok in 0.6.3)

Test environment

• Jenkins Version: 2.222.3
• AnsiColor Version: 0.7.0
• Hostsystem: Linux x64

Expected behavior

I would expect the colors/format to appear correctly when/if Jenkins console truncates long output (/console) and not only when the full output is displayed (/consoleFull).

Actual behavior

The escape sequences are printed raw on truncated console output. [clicking Full Log link displays the expected behavior]

Steps to reproduce the behavior

Any output that colorizes the output and is truncated by jenkins console doesn’t seem to be working as expected.

Thank you for the report. I had a lot of trouble trying to reproduce this.

Turns out this happens for Jenkins instances which never had a default, global ansicolor options set. My test box had (even if they are all re-set to defaults now) and this prevented me from encountering the bug.

This means that a dirty, short-term solution is to set a global color map and then immediately remove it.

I don’t have much free time at the moment but will try to come up with a permanent fix in the coming days.

For those of you which use Configuration as Code to manage Jenkins, here’s the config snippet that enables the global color map:

unclassified:
  ansiColorBuildWrapper:
    globalColorMapName: "xterm"

Maybe setting the global color map name to the empty string will also fix the problem.
