#magic

Code analyzer for the ooc programming language.

Linux quick install

If you only want to use the release and won't bother with compiling anything yourself, this quick guide is for you.

Install node 0.12 (Ubuntu)

Taken from here (active as of september 2015)

If the first one doesn't do it for you, go here (active as of september 2015)

• 1: Open up a terminal window
• 2: sudo apt-get update && sudo apt-get upgrade
• 3: curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash -
• 4: sudo apt-get install -y nodejs

Install magic

• 1: Download the latest release and unpack it to a location of your choosing
• 2: cd MAGIC_FOLDER
• 3: sudo cp magic /usr/local/bin

Done! Now head over to the usage section.

very much readme

Very, very early alpha stage.

• The lexer must be improved and streamlined.
• A parse tree is yet to be implemented.
• The analyzer will work with a proper parse tree, once implemented. This will enable more complex checks. Right now, a limited set of checks has been hacked together using the token list generated from each file.
• A tab width of 4 is assumed.

requirements

Known to work on Linux (x64), status on other platforms is unknown at this time.

• 1: g++ 4.2 or newer (node.js requirement)
• 2: node.js
• 3: Typescript compiler (if you want to build it yourself)

if you don't have node.js and/or the Typescript compiler

First, install g++. Open up a terminal window and issue the following command, then follow the on-screen instructions.

sudo apt-get install g++

The node.js version provided by aptitude is outdated, so do not install via apt-get. Instead, download and unpack node.js into any folder, then follow the steps outlined below.

cd NODE_FOLDER
./configure
make
sudo make install

You may have to restart the terminal. Now that we've installed node.js, it's time to update npm (node package manager) and then install the Typescript compiler.

sudo npm install -g npm

sudo npm install -g typescript

Now verify that Typescript has been installed:

tsc --v

It should give you version 1.5.3 or greater.

installation

You can install magic in two different ways:

• Using the provided install script
• Using the pre-compiled release file

using the install script

magic's default install location is /usr/local/bin, which requires you to run the installer as root.

cd MAGIC_FOLDER
sudo ./install

If you want to install magic to a different location, you may give the installer that location as an argument. Depending on the location, you may have to run the installer as root.

./install ~/apps/bin

The installer will build the project for you. For ease of use, make sure you have magic's location in your $PATH. To find out, issue the command echo $PATH in the terminal.

using the release

• Download the latest release and unpack it
• Move the file magic to a location of your choosing (we recommend /usr/local/bin or any other standard bin directory(this may require sudo))
• That's it.

build

If you have modified magic and want to rebuild it, make sure you're in magic's root folder, then do one of the following:

• Compile directly: tsc. The build output is located in ./build. To run magic, issue node ./build/magic.js TARGET_DIR
• Run the installer: See Using the install script

usage

If you don't specify a target directory, your current location will be used.

magic [TARGET DIRECTORY]

magic ~/projects/my_awesome_project/source

• The target directory is processed recursively.
• The analyzer output (if any) is currently directed to the console. For projects with a lot of violations, redirecting to a file is recommended.

magic ~/projects/my_awesome_project/source > violations.txt

If you want to run the analyzer on a single file, simply specify the filename. You may also specify a list of files, separated by a space.

magic ~/projects/my_awesome_project/source/math/Quaternion.ooc

If your shell supports wildcard expansion, you may also specify wildcards to process files that match a certain pattern, for example, to analyze all files that start with Matrix:

magic ~/projects/my_awesome_project/source/math/Matrix*.ooc

You may also sort the output of each file by line number, by using -s

magic -s [TARGET]

ignore list

If you want to prevent magic from analyzing certain folders or files in your project directory, create a file called .magicignore and put it in the root folder of your project. In this file you add everything you want to keep from magic, relative to the project root folder.

Example:

lib/somethirdpartylibrary
source/math/Transform.ooc

troubleshooting

Here are some problems that may occur along the way, and hopefully, solutions to them.

• I have installed magic, but can't seem to run it? Make sure the system knows where to look for it. Try executing command -v magic. The output should point to where magic is installed, if it is empty, then you need to add magic's location to your $PATH.
