I''m trying to add elements to an array with the plusingment operator.
However the following results in
err: Could not retrieve catalog from remote server: Error 400 on SERVER: Syntax
error at ''+>''; expected ''}'' at
/etc/puppet/modules/php/manifests/params.pp:17
(This isn''t a question of whether or not php53 will be happy with
php-pecl-memcache, its about extending arrays).
class php::params {
case $osmajor {
''5'': {
$phpService = ''php53''
$phpModules = [
''php-pecl-memcache'',
]
}
default: {
$phpService = ''php''
$phpModules = [
''php-pecl-memcached'',
]
}
}
$phpVersion = ''latest''
$phpModules +> [ "${phpService}-mysql",
"${phpService}-xml",
"${phpService}-mbstring",
"${phpService}-cli",
"${phpService}-gd",
"${phpService}-soap",
]
}

This does work though:
class php::params {
case $osmajor {
''5'': {
$phpService = ''php53''
$Modules = [
''php-pecl-memcache'',
]
}
default: {
$phpService = ''php''
$Modules = [
''php-pecl-memcached'',
]
}
}
$phpVersion = ''latest''
$phpModules = [ "${phpService}-mysql",
"${phpService}-xml",
"${phpService}-mbstring",
"${phpService}-cli",
"${phpService}-gd",
"${phpService}-soap",
$Modules,
]
}

This is a Puppet invariant. The plussignment operator gives the *illusion* of appending to an array variable that belongs to a different scope, but would normally be visible in the current scope as a result of dynamic scoping. It is best to think of it as creating a new variable of the same name in the current scope, with a value derived from the original one''s as directed by the plussignment. Plussignment cannot be applied to a variable that has already been declared in the current scope, either directly or by a different plussignment, on account of the prohibition against changing existing variables'' values. Also, be aware that scoping in Puppet does not follow the same rules as it does in many programming languages. Most blocks (delimited in Puppet by curly braces, {}) do not establish new scopes. Aside from the global scope, only class bodies, definition bodies, and node declarations establish new scopes. Because plussignment is inherently connected to dynamic scoping, and dynamic scoping is deprecated, it would be best to find a different way to do what you''re trying to do.
