Unicon (programming language)

Unicon (programming language) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Unicon (programming language) rather than just read about it. In short: Unicon is a programming language designed by American computer scientist Clint Jeffery with collaborators including Shamim Mohamed, Jafar Al Gharaibeh, Robert Parlett and others. Unicon descended from Icon and a preprocessor for Icon called IDOL.

Key takeaways

Unicon (programming language) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Unicon (programming language) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Unicon (programming language) from memory before moving on to harder problems.

Reference excerpt

Unicon is a programming language designed by American computer scientist Clint Jeffery with collaborators including Shamim Mohamed, Jafar Al Gharaibeh, Robert Parlett and others. Unicon descended from Icon and a preprocessor for Icon called IDOL. Compared with Icon, Unicon offers better access to the operating system as well as support for object-oriented programming. Unicon began life as a merger of three popular Icon extensions: an OO preprocessor named Idol, a POSIX filesystem and networking interface, and an ODBC facility. The name is shorthand for "Unified Extended Dialect of Icon."

Features Compared with Icon, many of the new features of Unicon are extensions to the I/O and system interface, to complement Icon's core control and data structures. Rather than providing lower-level APIs as-is from C, Unicon implements higher level and easier to use facilities, enabling rapid development of graphic- and network-intensive applications in addition to Icon's core strengths in text and file processing.

Feature list Classes and packages Exceptions as a contributed class library - see mailing list Loadable child programs Monitoring of child programs Dynamic loading of C modules (some platforms) Multiple inheritance, with novel semantics ODBC database access dbm files can be used as associative arrays Posix system interface 3D graphics True concurrency (on platforms supporting Posix threads) When run as a graphical IDE, the Unicon program ui.exe continues to offer links to Icon help. The official Unicon programming book in PDF format is a popular way to learn Unicon. The book includes an introduction to object-oriented development as well as UML. It includes useful chapters on topics such as the use of Unicon for CGI. Recent additions to Unicon include true concurrency.

Unicode Unicon is not yet Unicode-compliant. There are opportunities posted at a help-wanted page.

Worked examples

Example 1 — a first encounter with Unicon (programming language)

Start with the simplest possible case. Write down what Unicon (programming language) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Unicon (programming language) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Unicon (programming language) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Unicon (programming language)

In research: Unicon (programming language) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Unicon (programming language) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Unicon (programming language) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Icon programming language family, Pattern matching programming languages, SNOBOL programming language family, so understanding it makes those chapters shorter.
In everyday life: Look for Unicon (programming language) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
