Create a list of hash paths that match a given pattern. You can also generate a hash with only the matching paths.
gem install glob
Or add the following line to your project's Gemfile:
gem "glob"
There are two types of paths: include
and exclude
.
include
path adds that node to the new hash.exclude
path is the one started by !
, and will prevent that path fromRules may also have groups. Let's say you want to target en.*
and pt.*
; you
case set {en,pt}.*
rather than having two separate rules.
The latest rules have more precedence; that means that if you have the rule
*.messages.*
, then add a following rule as !*.messages.bye
, all
*.messages.*
but *.messages.bye
will be included.
glob = Glob.new(
site: {
settings: {
name: "Site name",
url: "https://example.com"
}
},
user: {
settings: {
name: "User name"
}
}
)
glob << "*.settings.*"
glob.paths
#=> ["site.settings.name", "site.settings.url", "user.settings.name"]
glob.to_h
#=> {
#=> site: {
#=> settings: {
#=> name: "Site name"
#=> }
#=> },
#=> user: {
#=> settings: {
#=> name: "User name"
#=> }
#=> }
#=> }
Notice that the return result will have symbolized keys.
If the key contain dots, then the result will use \\.
as the escape sequence.
Similarly, you need to escape keys with dots when filtering results.
glob = Glob.new(
formats: {
".txt" => "Text",
".json" => "JSON",
".rb" => "Ruby"
}
)
glob << "*"
glob.paths
#=> ["formats.\\.json", "formats.\\.rb", "formats.\\.txt"]
glob.to_h
#=> {:formats=>{:".json"=>"JSON", :".rb"=>"Ruby", :".txt"=>"Text"}}
# Remove all existing matchers
glob.matchers.clear
glob << "formats.\\.rb"
glob.paths
#=> ["formats.\\.rb"]
glob.to_h
#=> {:formats=>{:".rb"=>"Ruby"}}
You can set new keys by using .set(path, value)
:
glob = Glob.new
glob << "*"
glob.set "a.b.c", "hello"
glob.to_h
#=> {:a=>{:b=>{:c=>"hello"}}}
glob.paths
#=> ["a.b.c"]
# The non-hash value will be replaced in case the new path overlaps it
glob.set "a.b.c.d.e", "hello"
glob.to_h
#=> {:a=>{:b=>{:c=>{:d=>{:e=>"hello"}}}}}
glob.paths
#=> ["a.b.c.d.e"]
