------------------------------------------------------------ Application manager ----------------------------------------

Goal / Utilities

• Download and install applications (scripts, appImages, zip files containing other files...)
• Check information about installed apps
• Remove apps or update them

Downloading and installing applications

The app manager should be able to download files from the Internet. It should also be able to handle all kinds

For installing applications, the app manager will ask from the user what do:

Pro download procedure

• Ask for the name of the program, and its version, and if it is a CLI program

• Ask from the user what kind of application it is (folder: d, executable: exe, script: s, zip file: z)

  Application type	directory	executable	script	zip file
  First instruction	show to tree of the folder	Move the executable to its destination	Move the script to its destination	extract to .temp_app and show to tree
  Second instruction	Ask the user user to give the path of the main executable	Ask the user to give the command for it to run	Ask the user to give the command for it to run	Ask the user to give the path of the main executable
  Third instruction	Ask to user to give the command for it to run	Ask the user whether it needs a desktop file or not	Ask the user if it needs a desktop file or not	Ask the user to give the command for it to run
  Fourth instruction	Ask to user whether it needs a desktop file or not	Create a local manifest for the app & add the app to the global manifest	Create a local manifest for the app & add the app to the global manifest	Ask to user whether it needs a desktop file or not
  Fifth instruction	Move the folder to its destination	-	-	Move the folder to its destination
  Sixth instruction	Create a local manifest for the app & add the app to the global manifest	-	-	Create a local manifest for the app & add the app to the global manifest

• Desktop file creation

  • Open a file at the $user/local/applications/$app_name.desktop

  • add the name and the version

  • Properties	Icon	Aliases	terminal
    Demand	ask the user to give the path of an icon or URL	ask the user to give some aliases	terminal=$cli

• Local manifest creation & schema

  • Create a file called manifest.mf at $app_location

  Name	Version	Execution
  name=$name	version=$version	exec=$exec_command

• Adding the app to the global manifest

  • The global manifest is a binary file containing python dictionaries

  • The schema of this dictionary is:

    {name: $name, path: $path}

Global
