;;; Commentary:
|
||
|
||
;; The docstring for the function `type-break-mode' summarizes most of the
|
||
;; details of the interface.
|
||
|
||
;; This package relies on the assumption that you live entirely in Emacs,
|
||
;; as the author does. If that's not the case for you (e.g. you often
|
||
;; suspend Emacs or work in other windows) then this won't help very much;
|
||
;; it will depend on just how often you switch back to Emacs. At the very
|
||
;; least, you will want to turn off the keystroke thresholds and rest
|
||
;; interval tracking.
|
||
|
||
;; If you prefer not to be queried about taking breaks, but instead just
|
||
;; want to be reminded, do the following:
|
||
;;
|
||
;; (setq type-break-query-mode nil)
|
||
;;
|
||
;; Or call the command `type-break-query-mode' with a negative prefix
|
||
;; argument.
|
||
|
||
;; If you find echo area messages annoying and would prefer to see messages
|
||
;; in the mode line instead, do M-x type-break-mode-line-message-mode
|
||
;; or set the variable of the same name to t.
|
||
|

|
||
"Enable or disable typing-break mode.
|
||
This is a minor mode, but it is global to all buffers by default.
|
||
|
||
When this mode is enabled, the user is encouraged to take typing breaks at
|
||
appropriate intervals; either after a specified amount of time or when the
|
||
user has exceeded a keystroke threshold. When the time arrives, the user
|
||
is asked to take a break. If the user refuses at that time, Emacs will ask
|
||
again in a short period of time. The idea is to give the user enough time
|
||
to find a good breaking point in his or her work, but be sufficiently
|
||
annoying to discourage putting typing breaks off indefinitely.
|
||
|
||
The user may enable or disable this mode by setting the variable of the
|
||
same name, though setting it in that way doesn't reschedule a break or
|
||
reset the keystroke counter.
|
||
|
||
If the mode was previously disabled and is enabled as a consequence of
|
||
calling this function, it schedules a break with `type-break-schedule' to
|
||
make sure one occurs (the user can call that command to reschedule the
|
||
break at any time). It also initializes the keystroke counter.
|
||
|
||
The variable `type-break-interval' specifies the number of seconds to
|
||
schedule between regular typing breaks. This variable doesn't directly
|
||
affect the time schedule; it simply provides a default for the
|
||
`type-break-schedule' command.
|
||
|
||
If set, the variable `type-break-good-rest-interval' specifies the minimum
|
||
amount of time which is considered a reasonable typing break. Whenever
|
||
that time has elapsed, typing breaks are automatically rescheduled for
|
||
later even if Emacs didn't prompt you to take one first. Also, if a break
|
||
is ended before this much time has elapsed, the user will be asked whether
|
||
or not to continue. A nil value for this variable prevents automatic
|
||
break rescheduling, making `type-break-interval' an upper bound on the time
|
||
between breaks. In this case breaks will be prompted for as usual before
|
||
the upper bound if the keystroke threshold is reached.
|
||
|
||
If `type-break-good-rest-interval' is nil and
|
||
`type-break-good-break-interval' is set, then confirmation is required to
|
||
interrupt a break before `type-break-good-break-interval' seconds
|
||
have passed. This provides for an upper bound on the time between breaks
|
||
together with confirmation of interruptions to these breaks.
|
||
|
||
The variable `type-break-keystroke-threshold' is used to determine the
|
||
thresholds at which typing breaks should be considered. You can use
|
||
the command `type-break-guesstimate-keystroke-threshold' to try to
|
||
approximate good values for this.
|
||
|
||
There are several variables that affect how or when warning messages about
|
||
imminent typing breaks are displayed. They include:
|
||
|
||
`type-break-mode-line-message-mode'
|
||
`type-break-time-warning-intervals'
|
||
`type-break-keystroke-warning-intervals'
|
||
`type-break-warning-repeat'
|
||
`type-break-warning-countdown-string'
|
||
`type-break-warning-countdown-string-type'
|
||
|
||
There are several variables that affect if, how, and when queries to begin
|
||
a typing break occur. They include:
|
||
|
||
`type-break-query-mode'
|
||
`type-break-query-function'
|
||
`type-break-query-interval'
|
||
|
||
The command `type-break-statistics' prints interesting things.
|
||
|
||
Finally, a file (named `type-break-file-name') is used to store information
|
||
across Emacs sessions. This provides recovery of the break status between
|
||
sessions and after a crash. Manual changes to the file may result in
|
||
problems."

If called interactively, the user is prompted for their guess as to how

many words per minute they usually type. This value should not be your

maximum WPM, but your average. Of course, this is harder to gauge since it

can vary considerably depending on what you are doing. For example, one

tends to type less when debugging a program as opposed to writing

documentation. (Perhaps a separate program should be written to estimate

average typing speed.)

From that, this command sets the values in `type-break-keystroke-threshold'

based on a fairly simple algorithm involving assumptions about the average

length of words (5). For the minimum threshold, it uses about a fifth of
|
||
the computed maximum threshold.
|
||
|
||
When called from Lisp programs, the optional args WORDLEN and FRAC can be
|
||
used to override the default assumption about average word length and the
|
||
fraction of the maximum threshold to which to set the minimum threshold.

FRAC should be the inverse of the fractional value; for example, a value of

2 would mean to use one half, a value of 4 would mean to use one quarter, etc."
