Attached is an Emacs program for vocabulary drilling. I wrote it quite some
time ago and planned to release back then but got distracted. Well, better
is late than never.
The program uses simple text files with colon-separated values as
dictionaries.
Enjoy,

;; voctest.el - an Emacs vocabulary test program

;; Commentary:
;; Voctest allows you to test your vocabulary, based on a dictionary.
;; It displays a word and a number of translations, where only one of
;; them is correct. User responds by pressing a number, corresponding
;; to the "right" translation. If a user presses 'q' (case doesn't matter)
;; the program quits.
;; The following goodies are supported:
;; 'c' - toggle automatic display of the correct answer if the user
;; makes a mistake (default: OFF)
;; '?' - give a quick hint for a number of seconds, defined by the value
;; of the `voctest-hint-time' variable. After a hint, the answer
;; is not counted.
;; The program is not restricted to translations only. The structure of the
;; dictionary file allows you to use other things - for example to test
;; your knowledge of words' gender in French or German, or the way
;; to write a word in Kanji, based on it's Hiragana spelling (well, I'm
;; not sure the latter will work, since the Japanese codeset may use ':')
;; Moreover, in the future multi-field dictionaries will be supported,
;; thus allowing various types of testing for the same dictionary.
;; The number of choices displayed is defined by the `voctest-num-choices'
;; variable. It must be in the [2..9] region.
;; The function to start is 'voctest'. You will be prompted for a
;; dictionary file to use. By default, the file is looked in the directory,
;; specified by a `voctest-dictionary-directory' variable. The default file
;; is specified by the `voctest-default-file' variable.
;; The dictionary in the file consists of entries. Each entry occupies
;; a line and has the following structure:
;;
;; field1 : field2 : ... : fieldN
;;
;; for example `field1' may be a word, `field2' - it's article, `field3/ -
;; it's translation in Russian, and `field4' - translation in Hebrew.
;; Spaces and tabs don't matter.
;; The test direction is specified by the `voctest-test-direction' variable.
;; It is a pair of numbers, where the first one is the field number to use
;; (starting with 0) for words in questions, and the second one - the field
;; number to fetch the answer choices. The NIL symbol instead of number will
;; make voctest fetch the last entry in the article
;; For highlighting, the following faces are defined:
;; voctest-question-face - for the word in question
;; voctest-answer-face - for the answer choices
;; voctest-right-count-face - for the `Right' count
;; voctest-wrong-count-face - for the `Wrong' count
