** Algorithm details
-*** Why?
-Based on a quick count, similar programs are implemented in 6 languages, 9 platforms and 15+ projects. The core algorithm is choosing a word, an accent character and an interval to display it, and how to do that best is quite important. However, how exactly each project implements that algorithm is generally buried in unrelated code, and mostly undocumented. It is extremely difficult and time consuming to figure out the exact algorithm and differences between them for each project, and I don't think it's hardly ever been done. This sucks. Users would like to know so they can pick one. Developers would like to know so that they can improve their implementation of the algorithm.
-
-So, I am opening a bug on every project I find, asking them to document what file and function(s) their algorithm is implemented in, and preferably to document it in english as well. The following is an example.
-
-*** Algorithm code location
-This project's implementation is located in ./spray.el
-The functions =spray--word-at-point=, =spray--update= and =spray-start= contain the main of the algorithm. Word splitting is also duplicated the same way as in those functions throughout ./spray.el.
+*** Main algorithm code location
+In =./spray.el=, the functions =spray--word-at-point=, =spray--update= and =spray-start= contain the main algorithm of choosing a word, an accent character and an interval to display it. Word splitting is also duplicated the same way as in those functions throughout ./spray.el.
*** Algorithm translated from code to english
-words are split at space, tab and newline characters, and if any of the characters =.!?;= appear in a word, a blank word is appended to the current word
+Words are split at space, tab and newline characters, and if any of the characters =.!?;= appear in a word, a blank word is appended to the current word.
-each word is displayed for (60 / the choosen wpm) seconds, except if the word contains any of =:,= or is greater than 9 characters long, in which case it is displayed for twice as long
+Each word is displayed for (60 / the choosen wpm) seconds, except if the word contains : or , or is greater than 9 characters long, in which case it is displayed for twice as long.
The accent location is chosen as the nth character in a word, depending on its length, based on the following table
| length | accent position |
| 6-9 | 3 |
| 10-13 | 4 |
| 14+ | 5 |

+*** Why?
+Based on a quick count, similar programs are implemented in 6 languages, 9 platforms and 11+ projects. Every one has a similar algorithm to choose a word, an accent character and an interval to display it. How to do that best is quite important. However, how each project does it is generally buried in unrelated code, and mostly undocumented. It is prohibitively time consuming to figure out the algorithm and differences between them for each project. This sucks. Users would like to know so they can pick one. Developers would like to know so they can get ideas and spread improvements among different projects.
