Description

smc-get is a library and command-line tool for installing, uninstalling, etc. level packages from the Secret Maryo Chronicles Contributed Levels Repository.

Prototype Notice

This program is a prototype for functionality that will eventually be merged with Secret Maryo Chronicles. It is subject to change and should not be used for anything other then testing.

Usage

Using it as a command-line

smc-get's main purpose is to be used as a command-line utility. It should be executed in the syntax:

smc-get COMMAND [PARAMETERS...]

Where COMMAND is the command and PARAMATERS... are the parameters for that command.

To get help on the various commands, use the help command.

smc-get help [COMMAND]

Ommit the COMMAND if you want general usage information.

Configuration file

smc-get requires a configuration file when used as a commandline tool. By default it searches for smc-get.yml in the config/ subdirectory of your smc-get installation, then for smc-get-conf.yml in the user's home directory and then for the file specified via the -c commandline switch, if existant. Values set in later evaluated configuration files override those in prevously evaluated ones; see

smc-get help

for more explanation. If you want to use the CUI from your scripts, you can specify a config file via -c, but make sure it contains all possible options, otherwise those in the global or user-level config files may affect your program. See below for an example.

Be careful when using sudo, because it changes the environment variables. smc-get may not find your user-level configuration file when using sudo, because it derives the path from the USER environment variable which may get set to root when using sudo.

In the configuration file you can set some general options, look into the file which is quite self-explanatory. A sample configuration may look like this:

data_directory: "/usr/local/share/smc"
repo_url: "https://github.com/Luiji/Secret-Maryo-Chronicles-Contributed-Levels/raw/master/"

Using it as a library

smc-get, although mainly targetted at being a command-line utility, may also be used as a library. This is useful when, for instance, creating a GUI front-end.

To initialize the library, indicate which repository you are using and where you want smc-get to install the packages to (which is usually your SMC installation path)

SmcGet.setup(
  "https://github.com/Luiji/Secret-Maryo-Chronicles-Contributed-Levels/raw/master/",
  "/usr/local/share/smc"
)

For interacting with the SMC repository, smc-get exposes an object-oriented API centered around the SmcGet::Package class. After you initialized the library as explained above, you can query, install and uninstall packages.

pkg = SmcGet::Package.new("mypackage")
pkg.install

If the function fails, it will raise various exceptions. When creating a GUI, you should catch these exceptions and present them as message boxes.

begin
  Package.new("mypackage").install
rescue SmcGet::Errors::NoSuchPackageError
  alert 'No such package "mypackage"!'
end

All errors smc-get raises are subclasses of SmcGet::Errors::SmcGetError. That means, if you rescue from this exception, you can handle all package-related errors at once:

begin
  Package.new("mypackage").install
rescue SmcGet::Errors::SmcGetError => e
  alert e.message
end

Furhtermore, these error messages should have a pretty informative message set, so unless you want to localize the error messages you can just reach them through (the messages, not the whole exceptions, of course).

The configuration file only contains settings for the commandline user interface, so you don't need it here. If you want to use the CUI from your scripts, do

require "smc_get"
require "smc_get/cui"

cui = SmcGet::CUI.new(ARGV)
cui.start

The configuration file from the config/ directory will automatically be loaded as well as the user-level configuration file; you may specify another configuration file by placing the appropriate option in ARGV:

ARGV.unshift("-c")
ARGV.unshift("YOURCONFIGFILE.yml")

cui = SmcGet::CUI.new(ARGV)
cui.start
