tinygem - The fast ruby gem manager
tinygem is a simple ruby gem manager in a single file with only about 600 LOC. There are no dependencies except for ruby itself, not even rubygems.
- Manage multiple package environments for separate projects (Similar to rip)
- Simple and fast
- Can manage rubygems for multiple ruby versions at the same time (I tested 1.8, 1.9 and rubinius)
- RUBYLIB load path is exported by the tool
Why another package manager?
My linux distribution has really buggy rubygem support. Installation for multiple ruby versions doesn't work. And everyone knows rubygems is a fat hog. Yesterday I had enough and removed all system gems.
After investigating other package managers for a while, the alternatives didn't really satisfy me: the concept of rip is good but it is too hacky with all those small scripts. Therefore it is very difficult to debug. Actually it didn't work at all for me due to gems with packaging standard violations.
Besides it depends on external package managers like rubygems or rpg which are used for fetching gems etc. Finding gems in the index and fetching them is quite an easy task using a bit tar-magic.
Conclusion: I wanted something simple to deploy, at best a single script with no external dependencies and definitely no dependency to rubygems. And I wanted the possibility to manage gems for multiple ruby versions without much hassle. So here it is: The package tinygem!
Beware of bugs in the above code; I have only proved it correct, ... ;) - no really, this thing was written in one day - no promises!
Very simple: Copy the file 'tinygem' and put it on the search path.
Install a gem, export the tinygem environment variables and use the installed gem (In this case rake).
$ tinygem install rake $ `tinygem export base 18` $ rake
$ tinygem tinygem: Simple ruby package manager Usage: tinygem <command> [options] Commands: env Manage environment export Export environment variables (search paths) index Update package index install Install package list List installed packages remove Remove package search Search package in the index (wildcards supported) update Update packages
Create/Switch to environment
tinygem env test Environment test created Environment test is active
$ tinygem env rm test Environment test removed Environment base is active
Export environment variables
Export environment variables (enable installed packages)
$ `tinygem export test 18`
Do not forget the backticks! Otherwise the variables will not be evaluated in the shell and you will see something like this
$ tinygem export test 18 export RUBYLIB=... PATH=...
Update package index
$ tinygem index Fetch http://rubygems.org/latest_specs.4.8.gz Fetch http://rubygems.org/specs.4.8.gz Fetch http://rubygems.org/prerelease_specs.4.8.gz
Install a package in the active environment.
$ tinygem install rake (test 18) rake-0.8.7 installed (test 19) rake-0.8.7 installed (test rbx) rake-0.8.7 installed
The first word in the parantheses is the environment, the second is the ruby version. You can install packages only for specific ruby implementations, in this case ruby 1.8 and rubinius.
$ tinygem install -r 18 -r rbx rake (test 18) rake-0.8.7 installed (test rbx) rake-0.8.7 installed
Install a specific version:
$ tinygem install rake-0.8.4 (test 18) rake-0.8.4 installed (test 19) rake-0.8.4 installed (test rbx) rake-0.8.4 installed
List installed packages
$ tinygem list rbx 18 19 rbx nokogiri 18.104.22.168 22.214.171.124 126.96.36.199 rake 0.8.7 0.8.7 0.8.7 test (active) 18 19 rbx rake 0.8.7 0.8.7
Remove package from the active environment.
$ tinygem remove rake (test 18) rake-0.8.7 removed (test 19) rake-0.8.7 removed (test rbx) rake-0.8.7 removed
Ruby implementations can be specified using '-r' as for 'tinygem install'.
Search a package
This command shows all available versions in the index. Wildcards are supported.
$ tinygem search creol* creole-0.3.6 creole-0.3.3 creole-0.3.4 creole-0.3.5 creole-0.3.6
Update a package
$ tinygem update (test 18) rake-0.8.4 replaced with rake-0.8.7 (test 19) rake-0.8.4 replaced with rake-0.8.7 (test rbx) rake-0.8.4 replaced with rake-0.8.7
- Fork tinygem
- Create a topic branch - git checkout -b my_branch
- Push to your branch - git push origin my_branch
- Create an issue with a link to your branch
- Write test cases
- Extensive testing with different gems
- Support for different package sources (git etc)
- Configurable gem servers
- More strict dependency checking
