Org-JuliaLang

• IniFile.jl :: Reading and writing Windows-style INI files.
• JLD.jl :: HDF5 interface for the Julia language to save and load julia variables while preserving native types.
• JSON.jl :: JSON parsing and printing.

---

Data Types

• ASCIIByte.jl :: Julia package to deal with Characters of 8 bits.
• AutoFormat.jl
• BigRationals.jl :: A BigRational package for Julia using GMP.
• Codecs.jl :: Common data encoding algorithms.
• DanaTypes.jl :: Types for continuous variables or parameters.
• DictViews.jl :: KeysView and ValuesView types for dynamic low-overhead views into the entries of dictionaries.
• DotPlusInheritance.jl :: Expression parser that simulates type inheritance.
• EMLTranslator.jl :: Adds Inheritance to julia composite type.
• FixedPointNumbers.jl :: This library exports fixed-point number types. A fixed-point number represents a fractional, or non-integral, number. In contrast with the more widely known floating-point numbers, fixed-point numbers have a fixed number of digits (bits) after the decimal (radix) point. They are effectively integers scaled by a constant factor.
• Formatting.jl :: A Julia package to provide Python-like formatting support.
• FreeTypeAbstraction.jl :: A Julian abstraction layer over FreeType.jl.
• frange
• ImagineFormat.jl :: Read .imagine file formats in Julia.
• jenks.jl
• julia-prettyshow :: A module to provide simple pretty printing facilities with base functionality for indentation etc, and a pshow (pretty show) implementation for julia ASTs.
• LHEF.jl :: Quick and dirty implementation of the Les Houches Event Format, for particle Physics, in terms of Fortran commonblocks where the information is embedded in a minimal XML-style structure.
• MacroTools.jl :: A library providing helpful tools for writing macros, notably a very simple templating system with some functions.
• Modifyfield.jl :: It creates functions to modify immutable fields of a composite type inside a container.
• MonkeyString.jl :: Fast string implementation inspired by SpiderMonkey.
• MPFI.jl :: A MPFI wrapper for Julia.
• MutableStrings.jl :: Mutable string types for Julia.
• MUtils.jl :: channels(), tspaces(), kvspaces() and more.
• Netpbm.jl :: Load and save Netpbm images in Julia. The Netpbm format is a graphics format using the extensions portable pixmap format (PPM), the portable graymap format (PGM) and the portable bitmap format (PBM), collectively referred as the portable anymap format (PNM).
• ReTerms.jl :: Package providing abstract random-effects terms and specific types.
• Ratios.jl :: Faster Rational-like types for Julia.
• Scalar.jl :: Scalar Types.
• SimpleStructs.jl :: Easy to use struct definition with defaults and value constraints, as well as auto-defined user-friendly constructors.
• [StringDistances.jl](https://github.com/matthieugomez/StringDistances.jl] :: String Distances in Julia.
• TexExtensions.jl :: Tex Pretty printing of Julia Base types.
• Units.jl :: Infrastructure for handling physical units for the Julia programming language.
• YAML.jl :: A flexible data serialization format that is designed to be easily read and written by human beings.

Type Parameters

• AutoTypeParameters.jl :: A Julia library to reversibly encode "any" value so that it can be used as a type parameter.
• FileIO2.jl :: File Object Type Hierarchy.
• FreeType.jl :: FreeType 2 bindings API wrapper.
• Parameters.jl :: Types with default field values, keyword constructors and (un-)pack macros.
• StringInterpolation.jl :: String interpolation for non-standard string literals.
• Strings.jl :: Testing out a new String representation.
• Traits.jl :: Traits package contracts on a type or a tuple of types and allows dispatch to work with them.
• TupleTypes.jl :: A testbed for an API to access Tuple parameters.
• TypeCheck.jl :: a type checker for Julia.
  • DOCS
  • "% coverage" for Number documentation, for example, what % of concrete types have abs() defined?
• Typeclass.jl :: Prototype typeclasses for Julia.
• TypeGraph.jl :: Visualize the Julia type system.
• TypeTree.jl :: source code and the interactive D3 visualization of a Julia type tree.

Programming Paradigms

Packages and resources that support various programming styles, Software Architecture and CS paradigms.

• BitRegs.jl :: Julia package for bit and register operations.
• InterVal.jl :: Intervals are inter-values, an interval is its values and their intra-values.
• LilKanren.jl :: A collection of Kanren implementations in Julia. miniKanren is an embedded Domain Specific Language for logic programming.
• Programming Language Theory :: Mathematics, Compilers, Functional Programming, and other papers.

Control Flow

• Hooking.jl :: Function entry hooking for julia and c functions.
• StatefulIterators.jl :: A stream-like wrapper around iterable objects.

Double Dispatch

• julia-pattern-dispatch :: Support for method dispatch in Julia based on pattern matching.

Functional Programming

• FunctionalUtils.jl :: Functional Julia – based on fogus/lemonad.
• Glob.jl :: Posix-compliant file name pattern matching.
• Lazy.jl :: Functional programming for Julia.
• Monads.jl :: Monadic expressions and sequences for Julia.
  • DOCS :: https://monadsjl.readthedocs.org/
• PatternDispatch.jl :: Method dispatch based on pattern matching for Julia.

Grammatical Evolution

• Evolution.jl :: Evolutionary Computation in Julia.
• GrammaticalEvolution :: An evolutionary technique that is similar to Genetic Programming (GP). However, unlike GP, it doesn't suffer the same problems with fixing damaged trees. Instead, it uses a grammar that is combined with a genome of integers. The genome is used to select which branch to follow for or-rules.

Macros

• RegexVar.jl :: A macro to fill variables straight from the string.
• Reexport.jl :: Julia macro for re-exporting one module from another.
• MacroUtils.jl :: Collection of Julia macros.

• UTime.jl :: Universal Time using local system timezone.

Meta Programming

• Sugar.jl.

Resources

• Meta Programming Manual

Multi-Threading

• OCCA.jl :: Julia interface into OCCA2 by @tcew, an extensible multi-threading programming API written in C++.

Program Analysis

Libs for memory management (malloc), bounds checking, literals and other base program analysis options.

• CallGraphs.jl :: A package for analyzing source-code callgraphs, particularly of Julia's src/ directory. The main motivation for this package was to aid in finding all functions that might trigger garbage collection by directly or indirectly calling jl_gc_collect; however, the package has broader uses.
• dataflow.jl :: Introduction to dataflow analysis using julia.
• ExpressionPatterns.jl :: Match, Destructure and Dispatch on expressions.
