Template Spec¶

Subcommands such as install and download accept one or more TEMPLATESPEC strings. The format is, in essence, almost identical to <package-name-spec> described in the DNF documentation.

In short, the spec is matched against the following list of NEVRA forms, in decreasing orders of priority:

name-[epoch:]version-release
name
name-[epoch:]version

Note that unlike DNF, arch is currently ignored as the template packages should all be of noarch.

One can also use globs in spec strings. See Section Globs for details.

Refer to Section NEVRA Matching in the DNF documentation for details.

Globs¶

Template Spec strings, repo ids, and search patterns support glob pattern matching. In particular, the following special characters can be used:

*: Matches any number of characters.
?: Matches exactly one character.
[]: Matches any enclosed character.
[!]: Matches any character except those enclosed.

In particular, note that {}, while supported by DNF, is not supported by qvm-template.
