Create gem wrappers for easy use of gems in cron and other system locations.
## Configuration / Defaults
In `~/.gemrc` you can overwrite this defaults:
```ruby
wrappers_path: GEM_HOME/wrappers
wrappers_environment_file: GEM_HOME/environment
wrappers_path_take: 1
```
It is not yet possible to put variables in the configuration,
only relative and full paths will work, open a ticket if you need variables.
## Generating wrappers
By default wrappers are installed when a gem is installed,
to rerun the process for all gems in `GEM_HOME` use:
```bash
gem wrappers regenerate
```
## Showing current configuration
To see paths that are used by gem run:
```bash
gem wrappers
```
## Environment file
User can provide his own `environment` file,
in case it is not available during generating wrappers it will be created using this template:
```erb
export PATH="<%= path.join(":") %>:$PATH"
export GEM_PATH="<%= gem_path.join(":") %>"
export GEM_HOME="<%= gem_home %>"
```
The path elements are calculated using this algorithm:
```ruby
ENV['PATH'].split(":").take(Gem.path.size + path_take)
```
