humextra

C++ library and programs for processing Humdrum data files.

Downloading

To download from a terminal if you have git installed on your system: git clone https://github.com/craigsapp/humextra

Otherwise you can download from the "zip" link at the top of this page (https://github.com/craigsapp/humextra/archive/master.zip). From the command line you can download the humextra ZIP file with this command in linux: wget https://github.com/craigsapp/humextra/archive/master.zip or use curl in OS X: curl -L https://github.com/craigsapp/humextra/archive/master.zip > master.zip Then unzip the file with this command: unzip master.zip

If you want to use the "git" command to download the humextra software, check to see if it is installed on your computer by typing this command in the terminal: which git It should return with the location of the command in the file structure, such as: /usr/bin/git If which git does not reply with any location, then you will have to install git. There are several ways to install it:

(1) In linux/unix, use some automated installation system which is installed on your computer. Some possible methods: yum install git, apt-get install git (Ubuntu), or emerge git (Gentoo).

(2) in OS X, use a package management system such as Homebrew (http://mxcl.github.io/homebrew) or MacPorts (http://macports.org). For example, to install Homebrew type the following command in the terminal: ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)" Homebrew and MacPorts are two OS X equivalents of apt-get/yum/emerge which are used to install software over the internet on linux systems.

In Mac OS X 10.9 (Mavericks) you should first install the Xcode command-line compiling tools using this command: xcode-select --install This will install xcode command-line tools over the internet after you click on a few pop-up windows.

For older Mac OS X versions, you will need to first install XCode from the Apple App Store (free). After installing XCode, go into its menu system and install the command-line development tools: (a) click on the Downloads tab in XCode (b) select "command line tools" (c) click on "install" button.

To install git after homebrew/macports and XCode command line tools are installed. type brew install git if using Homebrew, or sudo port install git if using MacPorts.

IDEs such as Eclipse (http://www.eclipse.org/downloads) have a git interface built into them. Other GUI-based git programs can be found at this link: http://git-scm.com/downloads/guis . These might be more appropriate for MS Windows, although you will have to install a unix terminal system such as cygwin (http://www.cygwin.com) to use the humextras program in MS Windows.

Compiling

To compile everything, type within the main humextra directory: make If using OS X, see the above notes on XCode in the Download section if you get a complaint about the make command not being found.

To compile only the humextra library: make library

To compile all humextra programs (after making the library): make programs

To compile a particular humextra program (after making the library): make humcat

To test that the programs have been compiled successfully, try typing: bin/keycor h://wtc/wtc1f01.krn which should reply with an estimate of the key for J.S. Bach's Well-Tempered Clavier, Book I fugue 1: The best key is: C Major

Installing

Compiled programs will be stored in the humextra/bin sub-directory. To use these programs from any location in the file system, you must tell the computer where to search for them. This is done in the terminal by adding the bin directory to the $PATH variable. Type echo $PATH to see what directories are currently being searched for commands. A lazy way of installing would be to copy the programs in humextra/bin into one of those locations, such as /usr/bin.

A more proper way would be to update the $PATH environmental variable. To do this you will need to know which shell you are using. Type echo $SHELL in the terminal to see which one: bash or tcsh are the two main ones. If you are using bash, then you can temporarily add humextra/bin to the $PATH with this command: PATH=$PATH:/location/of/humextra/bin To do the same in tcsh (without the outer set of quotes): setenv PATH $PATH":/location/of/humextra/bin"

For a more permanent installation the $PATH must be updated in the login scripts for bash/tcsh, either for a single user or for the entire system. For an individual user in bash add this line: export PATH=$PATH:/location/of/humextra/bin to the file ~/.bashrc . For tcsh, add the line setenv PATH $PATH":/location/of/humextra/bin to the file ~/.csrhc . Alternatively, the PATH environmental variable may need to be set in ~/.profile.If you want to install for all users on a computer system then you would add such lines to the system login script (which will vary on the version of unix you are using).

Online Commands

Most command-line tools from Humdrum Extras can be run online from this page. These online versions of the programs were compiled with Emscripten into JavaScript and run directly in your browser. Here are some of the online version of the humextra tools:

barnum, beat, blank, cint, dittox, extractx, gettime, harm2kern, hgrep, hum2xml, humcat, humtable, keycor, location, minrhy, mvspine, myank, pitchmix, prange, prettystar, ridx, rscale, runningkey, sample, satb2gs, scaletype, scordur, serialize, thrux, tntype, transpose, voicecount.

Updating

To update if you downloaded with git: git pull

Then either type make to recompile the external libraries, the humextra library and the programs, or type make update to compile just the humextra library and programs, or make libupdate to update only the library file without recompiling example programs. If you installed by download a ZIP file, then you would need to re-download another ZIP file with the updated code.

When using git to download and update the humextra repository, you can add these lines to ~/.gitconfig:

    [alias]
        hist = log --pretty=format:\"%h %ad | %s%d [%an]\" --graph --date=short

Then the command git hist will give a short listing of changes (one commit per line) sorted in reverse chronological order.

Documentation

All humextra programs include an option called --options which will list all of the defined options for the program along with their aliases and default values. For example here is the options list for the barnum program:

barnum --options
   r|remove=b
   s|start=i:1
   a|all=b
   debug=b
   author=b
   version=b
   example=b
   h|help=b

The line r|remove=b means that the barnum program accepts an option called -r or equivalently --remove which is a Boolean type of option (it does not take arguments, but is rather a switch to turn on a feature in the program). The line s|start=i:1 means that the -s or --start option requires an integer argument, and the default value if not given is the value 1. Options can also have types d for double arguments (floating-point numbers) and s for string arguments.
