ROS Ruby Client: rosruby ======= [ROS](http://ros.org) is Robot Operating System developed by [Willow Garage](http://www.willowgarage.com/) and open source communities. This project supports ruby ROS client. You can program robots by ruby, very easily. **Homepage**: http://otl.github.com/rosruby **Git**: http://github.com/OTL/rosruby **Author**: Takashi Ogura **Copyright**: 2012 **License**: new BSD License **Latest Version**: 0.2.0 Requirements ---------- - ruby (1.8.x/1.9.x) - ROS (electric/fuerte) - ROS requires python2.7 or more libraries Let's start --------------- Install ROS and ruby first. ROS document is [http://ros.org/wiki/ROS/Installation](http://ros.org/wiki/ROS/Installation) . You can install ruby by apt. ```bash $ sudo apt-get install ruby ``` Download rosruby into your ROS_PACKAGE_PATH. ````bash $ git clone git://github.com/OTL/rosruby.git ``` please add RUBYLIB environment variable, like below (if you are using bash). ```bash $ echo "export RUBYLIB=`rospack find rosruby`/lib" >> ~/.bashrc $ source ~/.bashrc ``` To use with precompiled electric release ----------------------- If you are using precompiled ROS distro, use the msg/srv generation script (rosruby_genmsg.py) If you are using ROS from source, it requires just recompile the msg/srv packages by rosmake rosruby. ```bash $ rosrun rosruby rosruby_genmsg.py ``` This converts msg/srv to .rb which is needed by sample programs. If you want to make other packages, add package names for args. For example, ```bash $ rosrun rosruby rosruby_genmsg.py geometry_msgs nav_msgs ``` Sample Source -------------- ## Subscriber ```ruby #!/usr/bin/env ruby require 'ros' require 'std_msgs/String' node = ROS::Node.new('/rosruby/sample_subscriber') node.subscribe('/chatter', Std_msgs::String) do |msg| puts "message come! = \'#{msg.data}\'" end while node.ok? node.spin_once sleep(1) end ``` ## Publisher ```ruby #!/usr/bin/env ruby require 'ros' require 'std_msgs/String' node = ROS::Node.new('/rosruby/sample_publisher') publisher = node.advertise('/chatter', Std_msgs::String) msg = Std_msgs::String.new i = 0 while node.ok? msg.data = "Hello, rosruby!: #{i}" publisher.publish(msg) sleep(1.0) i += 1 end ``` Note ---------------- Ruby requires 'Start with Capital letter' for class or module names. So please use **S**td_msgs::String class instead of **s**td_msgs::String. Try Publish and Subscribe ---------------------- You needs three terminal as it is often for ROS users. Then you run roscore if is not running. ```bash $ roscore ``` run publisher sample ```bash $ rosrun rosruby sample_publisher.rb ``` run subscription sample ```bash $ rosrun rosruby sample_subscriber.rb ``` you can check publication by using rostopic. ```bash $ rostopic list $ rostopic echo /chatter ``` Try Service? ---------------------- ```bash $ rosrun rosruby add_two_ints_server.rb ``` run client with args ('a' and 'b' for roscpp_tutorials/TwoInts) ```bash $ rosrun rosruby add_two_ints_client.rb 10 20 ``` and more... ---------------------- You need more tools for testing, generating documentations. ```bash $ sudo apt-get install rake gem $ sudo gem install yard redcarpet simplecov ``` do all tests ------------------------- run roscore if is not running. ```bash $ roscore ``` and run the unit tests. ```bash $ roscd rosruby $ rake test ``` documents -------------------------- you can generate API documents using yard. Document generation needs yard and redcarpet. You can install these by gem command like this. ```bash $ gem install yard redcarpet ``` Then try to generate documentds. ```bash $ rake yard ``` You can access to the generated documents from [here](http://otl.github.com/rosruby/doc/).
== Easily add colors, boxes, repetitions and emojis to your terminal output using pipes (|). Install using the Ruby Gem: > gem install pipetext Includes a library module which can be included in your code: require 'pipetext' class YellowPrinter include PipeText def print(string) write('|Y' + string + '|n') end end printer = YellowPrinter.new printer.print('This is yellow') The gem includes a command line interface too: > pipetext > pipetext '|Ccyan|n' Easily set your bash prompt colors using pipetext: > PS1=$(pipetext '|$|g\u|n@|g\h|n:|g\w|n$ ') Works with files: > pipetext <filename> Works with pipes too: > echo '|RRed test |u1f49c|n' | pipetext --- | pipe || & ampersand && Toggle (&) background color mode |& smoke |s white |W black text on white background |k&w red |r bright red |R red background &r green |g bright green |G green background &g blue |b bright blue |B blue background &b cyan |c bright cyan |C cyan background &c yellow |y bright yellow |Y yellow background &y magenta |m bright magenta |M magenta background &m --- Hex RGB color codes: Foreground |#RRGGBB Background &#RRGGBB Palette colors (256) using Hex: |p33&pF8 Clear Screen |! black with white background |K&w Blinking |@ white with magenta background |w&m invert |i smoke with green background |s&g Underlined |_ red with cyan background |r&c Italics |~ bright red with blue background |R&b Bold |+ green with yellow background |g&y Faint |. bright green with red background |G&r Crossed out |x normal color and background |n&n Escape Sequence |\ Center text using current position and line end number |{text to center} Add spaces to line end |; Set line end |]# Set current x,y cursor position |[x,y] Terminal bell |[bell] Move cursor up 1 line |^ Hide cursor |h Move cursor down 1 line |v Unhide cursor |H Move cursor forward 1 character |> Sleep timer in seconds |[#s] Move cursor back 1 character |< Sleep timer in milliseconds |[#ms] Capture variable |(variable name=data) Display variable |(variable name) Add to variable |(variable name+=data) Subtract from variable |(variable name-=data) Multiple variable |(variable name*=data) Divide variable |(variable name/=data) Copy variable to current number |(#variable name) |$ toggles [ and ] around empty sequences automatically for bash command prompts --- Emojis: https://unicode.org/emoji/charts/full-emoji-list.html |[Abbreviated CLDR Short Name] 😍 |[smiling face with heart-eyes] or ⚙ |[gear] 💤 |[zzz] 👨 |[man] 😍 |[sm f w he e] ✔ |U2714 ❌ |U274c ☮ |u262E 💎 |u1f48e 💜 |u1f49c --- Single or double line box mode with |- or |= ┌──┬──┐ ╔══╦══╗ +--+--+ <-- Draw this with this: |15 |-[--v--] |=[--v--] |o[--v--] │ │ │ ║ ║ ║ | | | |15 |-! ! ! |=! ! ! |o! ! ! 123456789012345├──┴──┤ ╠══╩══╣ +--+--+ |y1234567890|g12345|n|->--^--< |=>--^--< |o>--^--< 15 Spaces │ │ ║ ║ | | |c15|n Spaces|6 |-! ! |=! ! |o! !
