I want ruby to look for a file in the current folder that ends with a certain extension. The extension would be .app.zip
How would I do this?
To get the first matching file in the current directory, you can use:
file=Dir['*.app.zip'].first
Or to find all .app.zip files in certain directory, for example files/*.app.zip, you can use something like :
Dir[File.join('files', '*.app.zip')].each |file|
puts "found: #{file}"
end
Alternative to Dir:
require "find"
Find.find(folder) do |file|
puts "#{file}" if file=~/\.app\.zip/
end

I want to find all zipfiles under a directory, and list their filenames (not the full path) to the customer, and copy the zip files under the current directory. Below is my script:
require 'fileutils'
Dir.glob('/ABC/DEF/GHI/XYZ/hello_world_1.2*.zip') do |z_file|
if File.file?(z_file)
puts "#{z_file.to_s}"
FileUtils.cp_r(z_file, ".")
end
end
Output:
/ABC/DEF/GHI/XYZ/hello_world_1.2.345.zip
/ABC/DEF/GHI/XYZ/hello_world_1.2.678.zip
My script lists the complete path, for example /ABC/DEF/GHI/XYZ/hello_world_1.2.345.zip. Need some direction on this. Any suggestion to improve it to print the zipfile names is appreciated.
You can use File::basename to get just the basename (xxx.zip) for your file.
Working code is:
require 'fileutils'
Dir.glob('/ABC/DEF/GHI/XYZ/hello_world_1.2*.zip') do |z_file|
if File.file?(z_file)
puts File.basename("#{z_file.to_s}")
FileUtils.cp_r(z_file, ".")
end
end
I'm trying to move files from one folder to another via Ruby, but I'm stuck trying to get Pathname.new to work. For reference the files are being held in array as an inbetween from their normal dir. I know I could move it via CLI but I'd like the program to do it for me. This is what I have so far. I know it's wrong; I just don't get how to fix it.
temp_array.each {|song| song.path(Pathname.new("/Users/tsiege/Desktop/#{playlist_name}"))}
Have a look at FileUtils.mv:
require 'fileutils'
temp_array.each do |song|
FileUtils.mv song.path, "/Users/tsiege/Desktop/#{playlist_name}"
end
Be sure that the directory #{playlist_name} exists before you do, though:
FileUtils.mkdir_p "/Users/tsiege/Desktop/#{playlist_name}"
To move files you can use FileUtils.mv:
require 'fileutils'
FileUtils.mv 'from.ext', 'to.ext'
http://ruby-doc.org/stdlib-1.9.3/libdoc/fileutils/rdoc/FileUtils.html#method-c-mv
And if you want a list of files in a directory you can use:
Dir['/path/to/dir/*']
http://ruby-doc.org/core-1.9.3/Dir.html
Lastly, you may also want to check if you have a file or directory:
File.file? file
File.directory? dir
http://ruby-doc.org/core-1.9.3/File.html#method-c-file-3F
I am learning unit testing with PHP and am following the TDD session on tutsplus: http://net.tutsplus.com/sessions/test-driven-php/
I have set up a ruby watchr script to run the PHPUnit unit tests every time a file is modified using Susan Buck's script: https://gist.github.com/susanBuck/4335092
I would like to change the ruby script so that in addition to testing a file when it is updated it will test all files that inherit from it. I name my files to indicate inheritance (and to group files) as Parent.php, Parent.Child.php, and Parent.Child.GrandChild.php, etc so the watchr script could just search by name. I just have no idea how to do that.
I would like to change:
watch("Classes/(.*).php") do |match|
run_test %{Tests/#{match[1]}_test.php}
end
to something like:
watch("Classes/(.*).php") do |match|
files = get all classes that inherit from {match[1]} /\b{match[1]}\.(.*)\.php/i
files.each do |file|
run_test %{Tests/{file}_test.php}
end
end
How do I do the search for file names in the directory? Or, is there an easier/better way to accomplish this?
Thanks
EDIT
This is what I ended up with:
watch("#{Library}/(.*/)?(.*).php") do |match|
file_moded(match[1], match[2])
end
def file_moded(path, file)
subclasses = Dir["#{Library}/#{path}#{file}*.php"]
p subclasses
subclasses.each do |file|
test_file = Tests + file.tap{|s| s.slice!(".php")}.tap{|s| s.slice!("#{Library}")} + TestFileEnd
run_test test_file
end
end
Where Library, Tests, and TestFileEnd are values defined at the top of the file. It was also changed so that it will detect changes in subfolders to the application library and load the appropriate test file.
I'm not entirely certain, but i think this will work:
watch("Classes/(.*).php") do |match|
subclasses = Dir["Classes/#{match[1]}*.php"]
filenames = subclasses.map do |file|
file.match(/Classes\/(.*)\.php/)[1]
end
filenames.each do |file|
run_test "Tests/#{file}_test.php"
end
end
It's probably not the cleaneast way, but it should work.
The first line saves all the relative paths to files in the Classes directory beginning with the changed filename in subclasses.
in the map block I use a regex to only get the filename, without any folder names or the .php extensions.
Hope this helps you
I have a little piece of Ruby code:
files.each do |file|
FileUtils.mkdir_p(File.dirname(target))
FileUtils.cp_r(file, target, :verbose => true)
end
I would like to add a check like
if file is a folder
# do this
if file is a file
# do that
How do I implement in Ruby?
You can use File.directory?("name") and/or File.file?("name").
Also a good idea to check out Pathname#directory? and Pathname#file?
I am working on an API that needs to load all of the .rb files in its current directory and all subdirectories. Currently, I am entering a new require statement for each file that I add but I would like to make it where I only have to place the file in one of the subdirectories and have it automatically added.
Is there a standard command to do this?
In this case its loading all the files under the lib directory:
Dir["#{File.dirname(__FILE__)}/lib/**/*.rb"].each { |f| load(f) }
require "find"
Find.find(folder) do |file|
next if File.extname(file) != ".rb"
puts "loading #{file}"
load(file)
end
This will recursively load each .rb file.
like Miguel Fonseca said, but in ruby >= 2 you can do :
Dir[File.expand_path "lib/**/*.rb"].each{|f| require_relative(f)}
I use the gem require_all all the time, and it gets the job done with the following pattern in your requires:
require 'require_all'
require_all './lib/exceptions/'
def rLoad(dir)
Dir.entries(dir).each {|f|
next if f=='.' or f=='..'
if File.directory?(f)
rInclude(f)
else
load(f) if File.fnmatch('*.rb', f)
end
}
end
This should recursively load all .rb files in the directory specified by dir. For example, rLoad Dir.pwd would work on the current working directory.
Be careful doing this, though. This does a depth-first search and if there are any conflicting definitions in your Ruby scripts, they may be resolved in some non-obvious manner (alphabetical by folder/file name I believe).
You should have a look at this gem. It is quite small so you can actually re-use the code instead of installing the whole gem.
