Installation

To install the project in your Pharo image execute:

    Metacello new
    	githubUser: 'jecisc' project: 'SystemInteraction' commitish: 'v1.x.x' path: 'src';
    	baseline: 'SystemInteraction';
    	load

To add it to your baseline:

    spec
    	baseline: 'SystemInteraction'
    	with: [ spec repository: 'github://jecisc/SystemInteraction:v1.x.x/src' ]

Note that you can replace the #v1.x.x by another branch such as #development or a tag such as #v1.0.0, #v1.? or #v1.1.?.

Documentation

With this project it is possible to launch commands in different ways.

Blocking commands

If you want a blocking command returning the result of the command:

SICommand waitForCommand: 'ls'

You can add arguments:

SICommand waitForCommand: 'ls' arguments: { '-h'. '-l' }

You can also want you command to be a blocking command but to not care about the stdout of the command:

SICommand waitForCommand: 'ls' silently: true.
SICommand waitForCommand: 'ls' arguments: { '-h'. '-l' } silently: true

Non blocking commands

If you want a non blocking command:

SICommand executeCommand: 'open'

You can add arguments:

SICommand waitForCommand: 'mkdir' arguments: { 'testDir' }

Execute a script

It is possible to execute a script in two ways:

• If you have a file, you can execute it via SICommand class>>#executeScriptFile:silently:
• If you just have the script in the form of a text, you can execute it via SICommand class>>#executeScript:silently:

Utilities

This project also contains some utilities such has:

• Copying a folder to another using a system command
• Deleting a folder using a system command
• Unzipping a zip archive
• Creating a zip archive

dir := 'testDir' asFileReference.
dir ensureCreateDirectory.

(dir / 'test1.txt') ensureCreateFile.
(dir / 'test2.txt') ensureCreateFile.
(dir / 'test3.txt') ensureCreateFile.
(dir / 'test4.txt') ensureCreateFile.

dir2 := 'destination' asFileReference.
dir2 ensureCreateDirectory.

SICommand default copyAll: dir to: dir2.

SICommand default deleteAll: dir.
SICommand default deleteAll: dir2.


ZnClient new
	url: 'https://github.com/jecisc/SystemInteraction/archive/master.zip';
	downloadTo: 'master.zip'.
	

zip := 'master.zip' asFileReference.
unzipped := 'unzipDest' asFileReference.

SICommand default unzip: zip asFileReference to: unzipped.

SICommand default zip: { unzipped } to: 'testArchive.zip'.


SICommand default deleteAll: zip.
SICommand default deleteAll: unzipped.
SICommand default deleteAll: 'testArchive.zip'.

More might comes in the future.

Version management

This project use semantic versioning to define the releases. This means that each stable release of the project will be assigned a version number of the form vX.Y.Z.

• X defines the major version number
• Y defines the minor version number
• Z defines the patch version number

When a release contains only bug fixes, the patch number increases. When the release contains new features that are backward compatible, the minor version increases. When the release contains breaking changes, the major version increases.

Thus, it should be safe to depend on a fixed major version and moving minor version of this project.
