Forum: CFEngine Help Subject: Re: CFEngine Help: Re: Using defaults promises Author: zzamboni Link to topic: https://cfengine.com/forum/read.php?3,26481,26483#msg-26483
I'll let Mark or others with more insight into the language design pitch in, but I know that this is how CFEngine has always behaved: if a variable is not defined, then attempting to interpolate it results in the literal string being returned, rather than an empty string or something else. This is not completely unprecedented - for example, in many Unix shells, if you try to expand a glob expression that doesn't match any files, the default behavior is to return the glob string as is. E.g.: $ echo doesnotexist* doesnotexist* (although admittedly this behavior is also configurable in most shells). It would probably make sense and be useful to allow other behaviors when an undefined variable is used in interpolation. _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
