Updated: Catalan v0.0.2 (Wednesday 9-17)
Catalan: a combinatorics library for Julia, focusing mostly (as of now) on enumerative combinatorics and permutations. As overflows are expected even for low values, most of the functions always return BigInt, and are marked as such below.
This library provides the following functions: - bell(n): returns the n-th Bell number; always returns a BigInt; - catalan(n): returns the n-th Catalan number; always returns a BigInt; - derangement(n)/subfactorial(n): returns the number of permutations of n with no fixed points; always returns a BigInt; - doublefactorial(n): returns the double factorial n!!; always returns a BigInt; - fibonacci(n): the n-th Fibonacci number; always returns a BigInt; - hyperfactorial(n): the n-th hyperfactorial, i.e. prod([i^i for i = 2:n]; always returns a BigInt; - integer_partitions(n): returns a Vector{Int} consisting of the partitions of the number n. - jacobisymbol(a,b): returns the Jacobi symbol (a/b); - lassalle(n): returns the nth Lassalle number An defined in arXiv:1009.4225 (OEIS A180874); always returns a BigInt; - legendresymbol(a,p): returns the Legendre symbol (a/p); - lucas(n): the n-th Lucas number; always returns a BigInt; - multifactorial(n): returns the m-multifactorial n(!^m); always returns a BigInt; - multinomial(k...): receives a tuple of k_1, ..., k_n and calculates the multinomial coefficient (n k), where n = sum(k); returns a BigInt only if given a BigInt; - primorial(n): returns the product of all positive prime numbers <= n; always returns a BigInt; - stirlings1(n, k): the signed (n,k)-th Stirling number of the first kind; returns a BigInt only if given a BigInt.
Young diagrams ––––––– Limited support for working with Young diagrams is provided.
- partitionsequence(a): computes partition sequence for an integer partition a - x = a \ b creates the skew diagram for partitions (tuples) a, b - isrimhook(x): checks if skew diagram x is a rim hook - leglength(x): computes leg length of rim hook x - character(a, b): computes character the partition b in the ath irrep of Sn

Updated: Cbc v0.1.0 (Tuesday 9-16)
This is a Julia interface to the mixed-integer linear programming solver [Cbc]. Cbc is a high-performance open-source solver. A basic high-level `mixintprog` interface is provided through the [MathProgBase] package.
The supported platforms are Linux, OS X, and Windows. Binaries are provided for Windows and OS X, and will be installed by default. On Linux, Cbc will be automatically compiled from source. Ensure that a C++ compiler is installed first; on Debian-based systems, install the `build-essential` package.
[Cbc]: https://projects.coin-or.org/Cbc
### Using with [MathProgBase]
Cbc provides a solver object that can be passed to `mixintprog in MathProgBase (and used to create instances of the solver-independent `AbstractMathProgModel`` type):
using Cbc
using MathProgBase
mixintprog(..., CbcSolver(Option1=value1,Option2=value2,...))see the MathProgBase documentation for further information.
[MathProgBase]: https://github.com/JuliaOpt/MathProgBase.jl
Options are solver-dependent, and unfortunately not well documented. The following options are likely to be the most useful:
- ``seconds`` -- Solution timeout limit. (Must be a ``Float64``)
- ``logLevel`` -- Set to 1 to enable solution output.
- ``maxSolutions`` -- Terminate after this many feasible solutions have been found.
- ``maxNodes`` -- Terminate after this many branch-and-bound nodes have been evaluated.
- ``allowableGap`` -- Terminate after optimality gap is less than this value (on an absolute scale).
- ``ratioGap`` -- Terminate after optimality gap is smaller than this relative fraction.
- ``threads`` -- Set the number of threads to use for parallel branch & bound
The complete list of parameters can be found by running the `cbc executable and typing `?`` at the prompt.

Updated: ClusterManagers v0.0.3 (Saturday 9-27)
Currently support exists for :
- Sun Grid Engine - Scyld - HTCondor
Updated: Color v0.3.8 (Thursday 9-18)
   
This library provides a wide array of functions for dealing with color. This includes conversion between colorspaces, measuring distance between colors, simulating color blindness, and generating color scales for graphics, among other things.
## Colorspaces
What follows is a synopsis of every colorspace implemented in Color.jl. Any color value can be converted to a similar value in any other colorspace using the convert function.
E.g.
convert(RGB, HSL(270, 0.5, 0.5))Depending on the source and destination colorspace, this may not be perfectly lossless.

Updated: Compose v0.3.9 (Friday 9-26)
Compose is a vector graphics library for Julia. It forms the basis for the statistical graphics system Gadfly.
## Synopsis
Unilke most vector graphics libraries, compose is thoroughly declarative. Rather than issue a sequence of drawing commands, graphics are formed by sticking various things together and then letting the library figure out how to draw it. The "things" in this case fall one of three types: Property, Form, and Canvas. "Sticking together" is primary achieved with the compose function.
The semantics of composition are fairly simple, and once grasped provide a consistent and powerful means of building vector graphics.

Updated: DataArrays v0.2.1 (Friday 9-19)
  
The DataArrays package extends Julia by introducing data structures that can contain missing data. In particular, the package introduces three new data types to Julia:
- `NA`: A singleton type that represents a single missing value.
- `DataArray{T}`: An array-like data structure that can contain values of type `T`, but can also contain missing values.
- `PooledDataArray{T}`: A variant of `DataArray{T}` optimized for representing arrays that contain many repetitions of a small number of unique values -- as commonly occurs when working with categorical data.

Updated: Diversity v0.2.1 (Sunday 9-14)
Diversity is a Julia package that provides functionality for measuring alpha, beta and gamma diversity of subcommunities and ecosystems. It uses the diversity measures described in the arXiv paper [arXiv:1404.6520 (q-bio.QM)](http://arxiv.org/abs/1404.6520), *How to partition diversity*. It also provides a series of other related and older diversity measures through sub-modules for compatibility. This package is still in alpha, and so we do not guarantee its correctness, although we are aware of no issues with it. Please raise an issue if you find any problems.
- b47153d Richard Reeve: Added in Generalised Jaccard measure, generalisedjaccard()
- f9efb4b Richard Reeve: Corrected language to use subcommunity throughout code and documentation.
- 822364c Richard Reeve: Now exporting and testing the subcommunity functions (not community).
- 534b14b Richard Reeve: Fixed use of community and sub-community in other code.
- ff20a9b Richard Reeve: We replace beta with rho throughout. rho is 1 / beta (and similarly for the barred version), but we have realised this is the more fundamental concept. We add beta back in for compatibility reasons, but it is deprecated.

Updated: DoubleDouble v0.1.0 (Friday 9-19)
DoubleDouble.jl is a Julia package for performing extended-precision arithmetic using pairs of floating-point numbers. This is commonly known as "double-double" arithmetic, as the most common format is a pair of C-doubles (Float64 in julia), though DoubleDouble.jl will actually work for any floating point type. Its aim is to provide accurate results without the overhead of BigFloat types.
The core routines are based on the ideas and algorithms of [Dekker (1971)][dekker1971].
Interface –––––– The main type is Double, with two floating-point fields: hi, storing the leading bits, and lo storing the remainder. hi stored to full precision, rounded to nearest, hence for any Double x, abs(x.lo) <= 0.5*eps(x.hi). Although these types can be created directly, the usual interface is the double function:
julia> using DoubleDoublejulia> x = double(pi) Double{Float64}(3.141592653589793,1.2246467991473532e-16)
julia> eps(x.hi) 4.440892098500626e-16
The other type defined is a Single which is simply a wrapper for a floating-point type, but whose results will be promoted to Double.
Examples ––––-

- f7d944b Simon Byrne: fix typo in test/rem

New: GLAbstraction v0.0.3 (Monday 9-15)
A simple library, which makes the use of OpenGL a little bit more convinient and Julian.
### Features * Some linear algebrae, to do all kinds of transformations. * Aliases for ImmutableArrays, which are more GLSL alike (e.g. Vector3{Float32} -> Vec3, Matrix4x4{Float32} -> Mat4) * All the different glUniform functions are wrapped and the right function is determined via multiple dispatch (just works for ImmutableArrays and Real numbers) * Buffers and Texture objects are wrapped, with best support for arrays of ImmutableArrays. * Shader loading is simplified and offers templated shaders and interactive editing of shaders and type/error checks. * Offers the type RenderOject, which helps you preparing the OpenGL state to render data with a shader. * Event handling with React * Two camera types (PerspectiveCamera and OrthogonalCamera), which can be instantiated with a list of React signals from GLWindow. You can also supply your own signals. * Some wrappers for often used functions, with embedded error handling and more Julian syntax

Everything is in the wiki now: https://github.com/SimonDanisch/GLPlot.jl/wiki
New: GLText v0.0.3 (Monday 9-15)
New: GLWindow v0.0.3 (Monday 9-15)
Simple package to create an OpenGL window. It also wraps the window events into React signals. Supposedly more than one window creation library will be suppported, but so far it just creates them with GLFW. createwindow will return a screen object which basically just wraps all the signals and exposes the handle to the underlying glfw window. These are the exposed Signals:
Screen.inputs = [ :insidewindow => Input(false), :open => Input(true),:window_size => window_size(Vector{Float64}(width, height), :framebuffer_size => Input(Vector2(0)), :windowposition => Input(Vector2(0)), :unicodeinput => Input('0'), :buttonspressed => Input(IntSet()),# Set of pressed keyboard keys :buttondown => Input(0), :buttonreleased => Input(0), :mousebuttonspressed => Input(IntSet()), # Set of pressed mousekeys :mousedown => Input(0), :mousereleased => Input(0), :mouseposition => mouseposition, :mouseposition_glfw_coordinates => mouseposition_glfw, :scroll_x => Input(0), :scroll_y => Input(0) ]

Updated: Gadfly v0.3.9 (Friday 9-26)
Julia 0.3 
Julia 0.4 
  
Gadfly is a plotting and data visualization system written in Julia.
It's influenced heavily by Leland Wilkinson's book The Grammar of Graphics and Hadley Wickham's refinment of that grammar in ggplot2.
It renders publication quality graphics to PNG, Postscript, PDF, SVG. The SVG backend uses embedded javascript, powered by Snap.svg to add interactivity like panning, zooming, and toggling.
Check out the manual for more details and examples.

Updated: Jewel v0.9.0 (Wednesday 9-24)
Jewel.jl is a collection of IDE related code. It also handles communication with Light Table, although this is entirely seperate (in the LightTable folder) and may be removed eventually.
It handles things such as:
- Extensible autocompletion
- Pulling code blocks out of files (given a cursor position)
- Finding relevant documentation or method definitions at the cursor
- Detecting the module a file belongs to
- Evaluation of code blocks with correct file, line and module data
If you want any info on using this package as support for another IDE feel free to drop me a line.

Updated: JuMP v0.5.8 (Wednesday 9-24)
JuMP is a domain-specific modeling language for [mathematical programming] embedded in [Julia]. It currently supports a number of open-source and commercial solvers ([CPLEX], [COIN Clp], [COIN Cbc], [ECOS], [GLPK], [Gurobi], [Ipopt], [MOSEK], and [NLopt]) for a variety of problem classes, including [linear programming], [(mixed) integer programming], [second-order conic programming], and [nonlinear programming].
[mathematical programming]: http://en.wikipedia.org/wiki/Mathematical_optimization [Julia]: http://julialang.org/ [COIN Clp]: https://projects.coin-or.org/Clp [COIN Cbc]: https://projects.coin-or.org/Cbc [ECOS]: https://github.com/ifa-ethz/ecos [GLPK]: http://www.gnu.org/software/glpk/ [Gurobi]: http://www.gurobi.com/ [MOSEK]: http://mosek.com/ [CPLEX]: http://www-01.ibm.com/software/commerce/optimization/cplex-optimizer/ [Ipopt]: https://projects.coin-or.org/Ipopt [NLopt]: http://ab-initio.mit.edu/wiki/index.php/NLopt [linear programming]: http://en.wikipedia.org/wiki/Linear_programming [(mixed) integer programming]: http://en.wikipedia.org/wiki/Integer_programming [second-order conic programming]: http://en.wikipedia.org/wiki/Second-order_cone_programming [nonlinear programming]: http://en.wikipedia.org/wiki/Nonlinear_programming
JuMP makes it easy to specify and solve optimization problems without expert knowledge, yet at the same time allows experts to implement advanced algorithmic techniques such as exploiting efficient hot-starts in linear programming or using callbacks to interact with branch-and-bound solvers. JuMP is also fast - benchmarking has shown that it can create problems at similar speeds to special-purpose commercial tools such as AMPL while maintaining the expressiveness of a generic high-level programming language. JuMP can be easily embedded in complex work flows including simulations and web servers.
Our documentation includes an installation guide, quick-start guide, and reference manual.
Latest Release: 0.6.1 (via `Pkg.add`) * documentation * examples * Testing status:  
Development version: * documentation * examples * Testing status:    * Changes: see NEWS

Updated: Lazy v0.5.0 (Wednesday 9-24)
Pkg.add("Lazy")Lazy.jl provides Julia with the cornerstones of functional programming - lazily-evaluated lists and a large library of functions for working with them. It's also a repository for some neat macros, which you might be useful to you even if you don't want lazy lists (see below).
Firstly, the canonical examples, in Julia:
# Note : prepends. Don't forget the semicolon! # Fibonacci sequence defined in terms of itself: fibs = @lazy 0:1:(fibs + drop(1, fibs));take(20, fibs) #=> (0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181)
isprime(n) = @>> primes begin take_while(x -> x<=sqrt(n)) map(x -> n % x == 0) any; ! end
primes = filter(isprime, range(2));
take(20, primes) #=> (2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71)
If you've done any functional programming, you already know how to use Lazy.jl; just head down to the reference below to see what functions are available.

New: LevelDB (Tuesday 9-23)
LevelDB is Google's open source on-disk key-value storage library that provides an ordered mapping from string keys to binary values. In many applications where only key based accesses are needed, it tends to be a faster alternative than databases. LevelDB was written in C++ with a C calling API included. This module provides a Julia interface to LevelDB using Julia's ccall mechanism.

Updated: MachineLearning v0.0.2 (Friday 9-26)
  
The MachineLearning package represents the very beginnings of an attempt to consolidate common machine learning algorithms written in pure Julia and presenting a consistent API. Initially, the package will be targeted towards the machine learning practitioner, working with a dataset that fits in memory on a single machine. Longer term, I hope this will both target much larger datasets and be valuable for state of the art machine learning research as well.

Updated: Mathematica v0.1.1 (Wednesday 9-24)
The Mathematica.jl package provides an interface for using Wolfram Mathematica™ from the Julia language. You cannot use Mathematica.jl without having purchased and installed a copy of Mathematica™ from Wolfram Research. This package is available free of charge and in no way replaces or alters any functionality of Wolfram's Mathematica product.
The package provides is a no-hassle Julia interface to Mathematica. It aims to follow Julia's philosophy of combining high-level expressiveness without sacrificing low-level optimisation.
Pkg.add("Mathematica")` Provided Mathematica is installed, its usage is as simple as:
using Mathematica
Fibonacci(1000)
#=> 43466557686937456435688527675040625802564660517371780402481729089536555417949051890403879840079255169295922593080322634775209689623239873322471161642996440906533187938298969649928516003704476137795166849228875All of Mathematica's functions are available as both functions and macros, and splicing ($) works as you would expect:
Integrate(:(x^2), :x) # or @Integrate(x^2, x) #=> :(*(1//3,^(x,3)))@Integrate(log(x), {x,0,2}) #=> :(+(-2,log(4)))
eval(ans) # or @N($ans) # or N(ans) # or @N(Integrate(log(x), {x,0,2})) #=> -0.6137056388801094
Including those that return Mathematica data:
@Plot(x^2, {x,0,2})
#=> Graphics[{{{},{},{Hue[0.67, 0.6, 0.6],Line[{{4.081632653061224e-8,1.6659725114535607e-15},...}]}}}, {:AspectRatio->Power[:GoldenRatio, -1],:Axes->true, ...}]Mathematical data can participate in Julia functions directly, with no wrapping required. For example -
using MathLink
d = BinomialDistribution(10,0.2) #=> BinomialDistribution[10, 0.2]
probability(b::MExpr{:BinomialDistribution}) = b.args[2]
probability(d) #=> 0.2Julia compatible data (e.g. lists, complex numbers etc.) will all be converted automatically, and you can extend the conversion to other types.
Note that Mathematica expressions are not converted to Julia expressions by default. Functions/macros with the ::Expr hint (see below) will convert their result, but for others you must use convert or MathLink.to_expr.
Log(-1) #=> Times[0 + 1im, :Pi]
convert(Expr, ans) #=> :(*(0 + 1im,Pi))
N(Log(-1)) #=> 0.0 + 3.141592653589793imPrinting and warnings are also supported:
Print("hi")
#=> hi
@Print(x^2/3)
#=> 2
# x
# --
# 3
Binomial(10)
#=> WARNING: Binomial::argr: Binomial called with 1 argument; 2 arguments are expected.
#=> Binomial[10]Finally, of course:
WolframAlpha("hi") #=>

New: ModernGL v0.0.3 (Monday 9-15)
OpenGL bindings for OpenGL 3.0 and upwards. As OpenGL 3.0 has a lot of overlaps with OpenGL 2.1, OpenGL 2.1 is partly supported as well.
My philosophy is to keep this library strictly a low-level wrapper, so you won't find any error handling (besides for the function loading itself) or abstractions in this package.
Updated: Mustache v0.0.5 (Thursday 9-25)
Mustache is a text-based template system available in many languages.
This package ports over most of the mustache.js implementation for use in julia.
The mustache folks say:
Mustache is a logic-less template syntax. It can be used for HTML,
config files, source code - anything. It works by expanding tags in a
template using values provided in a hash or object.This code is a fairly faithful translation of code of https://github.com/janl/mustache.js/blob/master/mustache.js
All credit should go there. All bugs are my own.
Some basic examples with julia:
using Mustache;tpl = mt"the position is {{x}} and tail is {{y}}"
render(tpl, {"x"=>1, "y"=>2})
Yields
the position is 1 and tail is 2The first argument of render can be an IO instance. If it is not given, then sprint is used to provide one.
The non-standard string literal mt, used above to make the tpl object, is optional. If used, then the parsing is done at compile time and should be faster when used in a loop, say. A triple-quoted form is also available.
Similarly, we can use a module as a view such as Main:
x = 1; y = "two"
render(tpl, Main)gives
"the position is 1 and tail is two"Or, with a temporary module:
module TMP
x = 1; y = "two"
end
render("{{x}} and {{y}}", TMP) |> printlnOne can use Composite Kinds. This may make writing show methods easier:
using Distributions
tpl = "Beta distribution with alpha={{alpha}}, beta={{beta}}"
render(tpl, Beta(1, 2))gives
"Beta distribution with alpha=1.0, beta=2.0"One can iterate over data frames. Here is a template for making a web page:
tpl = "
<title>{{Title}}</title>
{{#d}}
{{/d}}
"This can be used to generate a web page for whos-like values:
_names = Array(String, 0)
_summaries = Array(String, 0)
m = Main
for s in sort(map(string, names(m)))
v = symbol(s)
if isdefined(m,v)
push!(_names, s)
push!(_summaries, summary(eval(m,v)))
end
end
using DataFrames
d = DataFrame(names=_names, summs=_summaries)
out = render(tpl, {"Title" => "A quick table", "d" => d})
print(out)
This can be compared to using an array of Dicts, convenient if you have data by the row:
A = [{"a" => "eh", "b" => "bee"},
{"a" => "ah", "b" => "buh"}]
tpl = mt"{{#A}}Pronounce a as {{a}} and b as {{b}}. {{/A}}"
render(tpl, {"A" => A}) |> print
yielding
Pronounce a as eh and b as bee. Pronounce a as ah and b as buh.
This project deviates from that of http://mustache.github.com in a few significant ways:
- The partials tag (the `>` tag) is not implemented.
- The tags are only demarked with `{{` and `}}`.
- Julian structures are used, not JavaScript objects. As illustrated, one can use Dicts, Modules, DataFrames

Updated: OpenStreetMap v0.6.0 (Friday 9-26)
This package provides basic functionality for parsing, viewing, and working with OpenStreetMap map data. The package is intended mainly for researchers who want to incorporate this rich, global data into their work, and has been designed with both speed and simplicity in mind, especially for those who might be new to Julia.
- 3763077 Ted Steiner: Wrote a basic simulator for a grid-based street network.
- b9b84c1 Ted Steiner: Moved function to add a new node from crop.jl to nodes.jl. No actual functionality changes.
- 55fb101 Ted Steiner: Wrote tests for grid streetmap simulation.
- 41f8c47 Ted Steiner: Changed coordinates.jl unit test to use approximate floating point comparison.
- d19b93a Ted Steiner: Updated floating point tests to use @test_approx_eq rather than @test.
- 2a284d4 Ted Steiner: Changed grid city simulation so that nodes are 100 meters apart rather than 1 meter.
- 3b11f7a Ted Steiner: Added option to construct a reverse routing network. It might be useful in some cases.
- 45ad68b Ted Steiner: Segment types now contain their distance.
- c07c132 Ted Steiner: Eliminated type checking on "dijkstra" in function "extractRoutes." It's not necessary, and I needed to be able to send different variants of the DijkstraStates algorithm. This shouldn't have an effect for any OpenStreetMap package users.

Updated: PyCall v0.4.9 (Thursday 9-18)
 
This package provides a @pyimport macro that mimics a Python import statement: it imports a Python module and provides Julia wrappers for all of the functions and constants therein, including automatic conversion of types between Julia and Python.
It also provides facilities for lower-level manipulation of Python objects, including a PyObject type for opaque Python objects and a pycall function (similar in spirit to Julia's ccall function) to call Python functions from the Julia language with type conversions.

Updated: Roots v0.1.7 (Wednesday 9-24)
This package contains simple routines for finding roots of continuous scalar functions of a single real variable. The basic interface is through the function fzero which dispatches to an appropriate algorithm based on its argument(s):
- `fzero(f::Function, a::Real, b::Real)` and `fzero(f::Function, bracket::Vector)` call the `find_zero` algorithm to find a root within the bracket `[a,b]`. When a bracket is used, the algorithm is guaranteed to converge to a value `x` with either `f(x) == 0` or at least one of `f(prevfloat(x)*f(x) < 0` or ``f(x)*f(nextfloat(x) < 0`. (The function need not be continuous to apply the algorithm, as the last condition can still hold.)
- `fzero(f::Function, x0::Real; order::Int=0)` calls a derivative-free method. The default method is a bit plodding but more robust to the quality of the initial guess than some others. For faster convergence and fewer function calls, an order can be specified. Possible values are 1, 2, 5, 8, and 16. The order 2 Steffensen method can be the fastest, but is in need of a good initial guess. The order 8 method is more robust and often as fast. The higher-order method may be faster when using `Big` values.
- `fzero(f::Function, x0::Real, bracket::Vector)` calls a derivative-free algorithm with initial guess `x0` with steps constrained to remain in the specified bracket.
- `fzeros(f::Function)` (for a polynomial function) and `fzeros(p::Poly)` (for a `Polynomials.jl` instance) calls `real_roots`, which implements a somewhat slow algorithm to find the real roots of a polynomial. The main issue involved with this function is the finding of a GCD for `p` and its derivative (which is used to find a square-free polynomial with the roots of `p`). This can be subject to numeric issues when the polynomial has high degree or nearby roots.
For convenience, when f is not a polynomial function, fzeros(f::Function, a::Real, b::Real) will split the interval [a,b] into many subintervals and apply fzero to each bracketing subinterval. This naive algorithm will miss double zeros that lie within the same subinterval and miss zeros where the function does not cross the $x$ axis.
- The `roots` function from the `Polynomials` package will find all the roots of a polynomial. Its performance degrades when the polynomial has high multiplicities. The `multroot` function is provided to handle this case a bit better. The function follows algorithms due to Zeng, ["Computing multiple roots of inexact polynomials", Math. Comp. 74 (2005), 869-903](http://www.ams.org/journals/mcom/2005-74-250/S0025-5718-04-01692-8/home.html). This function can be called via `multroot(f::Function)` or `multroot(p::Poly)`.
- For historical purposes, there are implementations of Newton's method (`newton`), Halley's method (`halley`), and the secant method (`secant_method`). For the first two, if derivatives are not specified, they will be computed using the `PowerSeries` package.

New: Showoff v0.0.1 (Friday 9-19)
Showoff provides an interface for consistently formatting an array of n things, e.g. numbers, dates, unitful values. It's used in Gadfly to label axes and keys.
It defines a function called showoff that takes an AbstractArray of some type and returns an array of strings of the same length.
If you want your type to look nice when plotted, just define a showoff function. Here's an example.
import Showoff
immutable Percent
value::Float64
end
function Showoff.showoff(xs::AbstractArray{Percent})
return [string(x, "%") for x in showoff([x.value for x in xs])]
end
Now we (and more importantly, Gadfly) can print percentages like:
map(println, showoff([Percent(100 * rand()) for _ in 1:20]))
60.505943%
73.255897%
97.477079%
43.330976%
69.023165%
52.580184%
13.011683%
22.718034%
93.843776%
29.875979%
64.110999%
91.203653%
91.534161%
80.684188%
81.674362%
11.530227%
30.498260%
38.876922%
35.444115%
8.857208%
Notice, that compared to show, these all have the same number of digits trailing the ., and look nice when right-aligned.
When no specialized showoff is defined, it falls back on the show function.

Updated: TextPlots v0.3.0 (Friday 9-19)
 
Fancy terminal plotting for Julia using Braille characters. Inspired by Drawille but not based on it due to its restrictive license (AGPL). TextPlots.jl is free for all under the MIT license.
TextPlots.jl aims for as much elegance and aesthetics as possible for a terminal (unicode) plotting library. It should be able to plot any continuous real-valued function, and any small-to-medium collection of points.

Updated: TikzPictures v0.1.2 (Saturday 9-20)
This library allows one to create Tikz pictures and save in various formats. It integrates with IJulia, outputting SVG images to the notebook.
In order to use this library, lualatex must be installed. The texlive and miktex distributions include lualatex. You must also have dvisvgm installed. On Ubuntu, you can get these, if not already present, by running sudo apt-get install texlive-latex-base and sudo apt-get install texlive-binaries.
You also need pdf2svg. On Ubuntu, you can get this by running sudo apt-get install pdf2svg. On Windows, you can download the binaries from http://www.cityinthesky.co.uk/opensource/pdf2svg/. Be sure to add pdf2svg to your path (and restart).

Updated: URIParser v0.0.3 (Thursday 9-25)
This Julia package provides URI parsing according to RFC 3986.
 
The main interaction with the package is through the URI constructor, which takes a string argument, e.g.
julia> using URIParser
julia> URI("hdfs://user:password@hdfshost:9000/root/folder/file.csv")
URI(hdfs://user:password@hdfshost:9000/root/folder/file.csv)
julia> URI("https://user:password@httphost:9000/path1/path2;paramstring?q=a&p=r#frag")
URI(https://user:password@httphost:9000/path1/path2;paramstring?q=a&p=r#frag)
julia> URI("news:comp.infosystems.www.servers.unix")
URI(news:comp.infosystems.www.servers.unix)
Additionally, there is a method for taking the parts of the URI individually, as well as a convenience method taking host and path which constructs a valid HTTP URL:
julia> URI("hdfs","hdfshost",9000,"/root/folder/file.csv","","","user:password")
URI(hdfs://user:password@hdfshost:9000/root/folder/file.csv)
julia> URI("google.com","/some/path")
URI(http://google.com:80/some/path)
Afterwards, you may either pass the API struct directly to another package (probably the more common use case) or extract parts of the URI as follows:
julia> uri = URI("https://user:password@httphost:9000/path1/path2;paramstring?q=a&p=r#frag")
URI(https://user:password@httphost:9000/path1/path2;paramstring?q=a&p=r#frag)
julia> uri.schema
"https"
julia> uri.host
"httphost"
julia> dec(uri.port)
"9000"
julia> uri.path
"/path1/path2;paramstring"
julia> uri.query
"q=a&p=r"
julia> uri.fragment
"frag"
julia> uri.specifies_authority
true
The specifies_authority may need some extra explanation. The reson for its existence is that RFC 3986 differentiates between empty authorities and missing authorities, but there is not way to distinguish these by just looking at the fields. As an example:
julia> URI("file:///a/b/c").specifies_authority
true
julia> URI("file:///a/b/c").host
""
julia> URI("file:a/b/c").specifies_authority
false
julia> URI("file:a/b/c").host
""
Now, while the file schema consideres these to be equivalent, this may not necessarily be true for all schemas and thus the distinction is necessary.
