From: Iain Patterson Date: Thu, 21 Nov 2013 18:39:07 +0000 (+0000) Subject: Set environment from the GUI at install time. X-Git-Tag: v2.19~6 X-Git-Url: http://git.iain.cx/?a=commitdiff_plain;h=277723e318f71a9ff9948e3286df509af79c1dc8;p=nssm.git Set environment from the GUI at install time. Added an extra Environment tab to set a newline-separated list of environment variables to replace or be added to the service environment. Input is validated by relaunching nssm itself with the proposed environment set. --- diff --git a/ChangeLog.txt b/ChangeLog.txt index 668cebb..e7cff08 100644 --- a/ChangeLog.txt +++ b/ChangeLog.txt @@ -1,5 +1,8 @@ Changes since 2.18 ----------------- + * Support AppEnvironmentExtra to append to the environment + instead of replacing it. + * The GUI is significantly less sucky.
