The world of correct words of our spell-checker is this list. If a typed-in word is not found in our list of correct words, we want to suggest a correction. We use the list we have downloaded in the preparation step above. If yes: the word is correct, if not: it’s incorrect. The solution is simple: have a list of correct words and check whether the typed-in word can be found in that list.

If not correct, offer a possible correction.

Check whether the typed-in word is correct.

How can we implement a basic working solution? Our spell checker has to do two things: Open your text editor of choice and look for “spell check” or just start typing a (miss-spelled) word into Google and you’ll receive a “did you mean xy” answer. I won’t risk too much if I assume that you have already seen a spell-checker work.

the very basic solution offers a lot of room for improvement and can be extended into an almost infinitely complex piece of software.

it is a practical application that everyone has seen before.

a (somewhat) working prototype can be developed very easily in a few lines of code.

I chose to use a spell checker as an example because of several advantages: That’s all that is needed to get started! Why a spell checker? If you don’t want to follow step-by-step the final project can be found in Github. Later we are using this to run our program outside the repl. The project is already executable, type in lein run and you will be greeted with the beloved “Hello World” message. Every new change we do requires to load our file again (there’s another way to accomplish that but for now, this is good enough) Use cursor up/down keys for going through the command history.

Load the program by entering (load-file "src/clojure_spellchecker/core.clj").

In the clojure-spellchecker run: lein repl.

Whenever it says: “try in REPL” do following steps:

Download and put it into the resources folder. A google search for “list of English words” gives us some choices, for example this long (109582) list of English words. project.clj will only require one change later on.src/clojure_spellchecker/core.clj is our main Clojure file.During this tutorial we are going to edit only two files: As we use Leiningen, this is going to be a snap. Preparations before we start Create a new project If you are an absolute beginner and don’t know the difference between a map and a list then this might be too much to start with. More information in the Clojure tutorial 3.

USING CLOJURE WITH NEDIT HOW TO

Know how to start a Clojure REPL (well, just type lein repl) and how it works. It’s quite dense, but I’d say spending an hour or so is sufficient for this tutorial. I recommend working through some of the Clojure tutorial 2.

Please follow the instructions on their website how to download and install it on your system.Ī little bit of Clojure knowledge would be good. I’d appreciate any feedback, especially from Clojure beginners, to let me know if you found that approach useful or not. I also try to not overwhelm the reader by giving just enough knowledge about Clojure to get started and answer the questions. That way, the reader is invited to come up with an own solution first before seeing the tutorial’s solution. The solutions are hidden and can be revealed by clicking on the. I’m going to describe in a step-by-step manner how to build a spell checker, but instead of just showing the solutions, questions and exercises are offered that build up to a working example. Programming is primarily learned by doing. I’d like to experiment with a slightly different type of tutorial. Applying min-key with partial distance to our word list.Aimed at Clojure beginners, gives just enough knowledge about the language to start developing. A step-by-step guide that invites the reader to participate. Summary: A Clojure tutorial building a spell checker.
