Cd
A Crystal library for walking through directories and manipulating file entries in its object-oriented way.
Installation
Add this to your application's shard.yml
:
dependencies:
cd:
github: mosop/cd
Code Samples
Changing the Current Directory
Cd.into("/path/to/foo") do
Dir.current # "/path/to/foo"
end
Further Inside
Cd.into("/path/to/foo") do |foo|
foo.cd("bar") do |bar|
bar.cd("baz") do
Dir.current # "/path/to/foo/bar/baz"
end
end
end
Searching Underlying Entries
Cd.into("/path/to/foo") do
foo.glob("src/**/*.cr") do |entry|
puts entry
end
end
Output Example:
/path/to/foo/src/foo/bar.cr
/path/to/foo/src/foo/version.cr
/path/to/foo/src/foo.cr
Helpers
Cd.into("/path/to/foo") do
foo.symlink?
foo.real_path
foo.join("bar", "baz")
foo.cp "/path/to/dst"
end
Creating Temporary Directories
Cd.tmp("/path/to/tmp") do |tmp|
tmp.cd("foo") do
Dir.current # "/path/to/tmp/fLC8nt/foo"
end
end
Dir.exists?("/path/to/tmp/fLC8nt/foo") # false
Make it Your Own
class SpecDir < Cd::DirEntry
def files
glob("**/*_spec.cr")
end
end
class CrystalDir < Cd::DirEntry
dir "spec", SpecDir
any "shard.yml"
def specs
spec.glob("*_spec.cr")
end
def shard
YAML.parse(shard_yml.read)
end
def version
shard["version"].as_s
end
end
kemal = CrystalDir.new("/path/to/kemal")
puts "Listing kemal (v#{kemal.version}) specs."
kemal.spec.files.each do |f|
puts f
end
Output example:
Listing kemal (v0.17.5) spec files.
