I am writing a formula to install some packages and would like to give the user control to install a version of his/her choice.
For example:
brew install git <-version->
I have been trying to find examples on how to implement this in my formula but cannot find any. I am kinda new to ruby so am struggling a bit. Can/how do I do this?
This is not supported by Homebrew. You may be interested in the homebrew-versions tap, which illustrates how Homebrew manages multiple versions of software.
The Formula Cookbook describes many of the things you can do in a formula, including how to accept options.

I am literally fighting for my life to get this machine setup for react native development. There have been crazy amount of problems and brew install do not work without arch -arm64. Is this a problem? Why is this?
PS: I am new to mac OS
Its just a question for knowledge
I encourage you to take a look at this repo, mac-dev-setup. All the formulae are pretty well maintained in the homebrew-core.
If you have further doubt, you can also raise in the discussions to get quicker response.
Im facing the following situation:
1. I wish to use TF 1.12 with MKL on windows
2. I have to use pip (our system supports only it so far)
problem is that currently Im unable to compile TF1.12 on windows (only on linux..).
I found that Conda has it right out of the box! so I was thinking
"hmm lets take it from Conda, probably someone has thought about it :)"
never the less, havent find any package or program that can do it, so I've decided to use Stack-overflows' power to look for the solution.
any help in this subject would be really appreciated
I have Python 3 on OSX Yosemite installed with Brew. I want to make some simple charts (like in Excel). I run Python from bash. Which library should I investigate, and the proper way to have it installed? I am looking for library which is easy to install, and then easy to use. Output probably png files?
matplotlib is a good choice.
How to install it on OS-X is mentioned in the installation FAQ.
Especially in combination with IPython notebooks it gives you a nice interactive environment to play with it.
Another alternative would be gnuplot. Pre-built packages are available.
It is not tied to Python, it is basically a domain specific language for graphing. There are python bindings available, gut it is also not difficult to use it with subprocess.
If you can use commercial libraries, you may also consider ChartDirector.
I found a lot of tutorials how to build application with Ruby and Qt, but i have no idea how anybody else will be able to run it! I am using Ubuntu 11.10, ruby 1.9.2 with rvm and:
rbqtapi -v output "QtRuby 2.0.5 using Qt-4.7.4"
P.S. I have no idea how to build *.deb, it will be my first desktop app, not web.
please have a look on http://shoesrb.com/ this is the best way I heard off for writing GUI apps.
Shoes has now not it's greatest time, but we put our best time to make it better, give it a try and someone will help you.
In case you are in need of assistance just ask as question on #shoes IRC channel on freenode servers.
If you're sold on QT, then you will need your users to install all the support libraries for QT (and anything else), then you can upload a rubygem to rubygems.org for your users to download.
Once, they've installed the support libraries, you'd only need to update your rubygem, which is fairly quick and easy for updates.
You may also wan to look at visualruby. It uses GTK. Then you'd install the GTK libraries instead of the QT ones.
http://www.visualruby.net
As far as .deb packages go, I tried to research the same thing with little success. The rubygems packaging system is designed to distribute ruby programs, so it is the best way to go. Also, you'll need to install different support libraries for different platforms. If you look at visualruby's install page, you can see how to install GTK for Linux and Windows.
Good Luck.
got a new mac, need to have it setup ready for development. I heard great things about macports, should i use it? Is it really easier than manually download and compile? anyone has any problems using it?
It is for typical ruby web development stuff.
thanks
Try homebrew. It's really good because it's highly optimized, and has no redundant packages.
It's also built in Ruby, which seems particularly relevant to you.
It really is easier than doing it manually. For example:
sudo port install gimp
will download, build, and install Gimp, plus all its dependencies. There are a lot of dependencies.
If you're doing "typical" stuff, the versions of stuff in MacPorts will be sufficient. Only if you need to be on the bleeding edge will you need to bypass MacPorts and download and install manually.
While macports can make installation easier, it's the difference between 4 commands (wget/tar/configure/make) and 1 command. Where macports really shines is in package management. If you're primarily interested in Ruby development, RubyGems might be all you need. If you're doing Ruby on Rails, macports will be quite helpful with all the non-ruby software you'll need. If you want to go completely GUI, you can use Porticus as a macports frontend.
I have had the occasional problem during the build phase, but that's under Tiger, which is behind the times.
I prefer macports, but some people like doing it themselves. Macports tends to be behind releases, but it's still good for me
The strongest problem with macports is that it's not cross platform, and it's hard to specify a well defined development scenario (e.g. you use Foo version 1.2.3, Bar version 0.5.6 etc.). It makes your life easier, but as of today, I still haven't found a decent solution to the definition and building of a development runtime environment which is efficient, easy and cross platform. See also this question.
So my suggestion is: go with macports, unless you want very strict control of your development environment.
You should use a package manager unless you have a well defined, specific reason not to.
'Course, I prefer fink.
