Time constant in emacs org-mode formula - emacs

Is there any way to have time constant in org spreadsheet formula? For example, I would like to have something like this:
#>$3=#>$5-'08:00:00'*vcount(#2..#-1)
to calculate how much longer I've been at work than i have to be :) The #>$5 is the total sum of hours I've been at work and #2..#-1 are the rows with days I've been working
Thanks a lot

It may help you:
| 16:00 | 1 | 8:00 |
| 1d 16:00 | 3 | 16:00 |
| 8:00 | 3 | -16:00 |
| -8:00 | 2 | -1d 0:00 |
| -1d 16:00 | -6 | 8:00 |
| 8:00 | 1 | 0:00 |

Creating a function using DrRacket that takes two lists and outputs it as a fraction

Write a function that takes two lists of numbers, numerators and denominators, and returns a list of fractions produced by dividing numerators by denominators. If one list is shorter than the other, assume that the corresponding numbers are all 1s. Don't worry about zeros in the denominators (it's ok if your function breaks when dividing by zero).
Input: (list 1 2 3) (list 1 3 5)
Output: (list 1/1 2/3 3/5)
You can solve it by recursion:
(define (r-map func l1 l2 (default-l1 1) (default-l2 1) (acc '()))
(cond ((and (null? l1) (null? l2)) (reverse acc))
((null? l1) (r-map func '() (cdr l2) default-l1 default-l2 (cons (func default-l1 (car l2)) acc)))
((null? l2) (r-map func (cdr l1) '() default-l1 default-l2 (cons (func (car l1) default-l2) acc)))
(else (r-map func (cdr l1) (cdr l2) default-l1 default-l2 (cons (func (car l1) (car l2)) acc)))))
The nice thing with this function is that you can change the default value for each list independently from each other.
Test it:
(define a '(1 2 3))
(define b '(4 5 6))
(define c '(10 20))
(define d '(40 50 60 70))
;; run all combinations of the four:
(let ((lists (list a b c d)))
(for*/list [(x lists)
(y lists)]
(list `(r-map ,x ,y ,default-l1 ,default-l2) '=> (r-map / x y))))
It returns:
Welcome to DrRacket, version 6.11 [3m].
Language: racket, with debugging; memory limit: 128 MB.
'(((r-map (1 2 3) (1 2 3) 1 1) => (1 1 1))
((r-map (1 2 3) (4 5 6) 1 1) => (1/4 2/5 1/2))
((r-map (1 2 3) (10 20) 1 1) => (1/10 1/10 3))
((r-map (1 2 3) (40 50 60 70) 1 1) => (1/40 1/25 1/20 1/70))
((r-map (4 5 6) (1 2 3) 1 1) => (4 2 1/2 2))
((r-map (4 5 6) (4 5 6) 1 1) => (1 1 1))
((r-map (4 5 6) (10 20) 1 1) => (2/5 1/4 6))
((r-map (4 5 6) (40 50 60 70) 1 1) => (1/10 1/10 1/10 1/70))
((r-map (10 20) (1 2 3) 1 1) => (10 10 1/3))
((r-map (10 20) (4 5 6) 1 1) => (2 1/2 4 1/6))
((r-map (10 20) (10 20) 1 1) => (1 1))
((r-map (10 20) (40 50 60 70) 1 1) => (1/4 2/5 1/60 1/70))
((r-map (40 50 60 70) (1 2 3) 1 1) => (40 25 20 70))
((r-map (40 50 60 70) (4 5 6) 1 1) => (10 10 10 70))
((r-map (40 50 60 70) (10 20) 1 1) => (4 2 1/2 60 70))
((r-map (40 50 60 70) (40 50 60 70) 1 1) => (1 1 1 1)))
Let's do this a bit more straightforwardly.
There are two simple cases:
Both lists are empty; the result is '()
Neither list is empty; cons the fraction of the cars onto the result of recursing.
Short-circuiting out the tricky cases:
(define (fractions ns ds)
(cond [(and (null? ns) (null? ds)) '()]
[(null? ns) 'only-denominators]
[(null? ds) 'only-numerators]
[else (cons (/ (car ns) (car ds)) (fractions (cdr ns) (cdr ds)))]))
Test:
> (fractions '() '())
'()
> (fractions '(1 2) '(4 5))
'(1/4 2/5)
> (fractions '(1 2 3) '(4 5))
'(1/4 2/5 . only-numerators)
> (fractions '(1 2) '(4 5 6))
'(1/4 2/5 . only-denominators)
If there are only numerators, the results are the same as those numerators, since x/1 is the same as x:
...
[(null? ds) ns]
...
And if there are only denominators, you divide 1 with each element.
This is easy with map:
...
[(null? ns) (map (lambda (d) (/ 1 d)) ds)]
...
In full:
(define (fractions ns ds)
(cond [(and (null? ns) (null? ds)) '()]
[(null? ns) (map (lambda (d) (/ 1 d)) ds)]
[(null? ds) ns]
[else (cons (/ (car ns) (car ds)) (fractions (cdr ns) (cdr ds)))]))
Test:
> (fractions '() '(4 5 6))
'(1/4 1/5 1/6)
> (fractions '(1 2 3) '())
'(1 2 3)
> (fractions '(1 2 3) '(4 5))
'(1/4 2/5 3)
> (fractions '(1 2) '(4 5 6))
'(1/4 2/5 1/6)

But using test8 it gives an error:
7 is not a string designator.
Which led me to write a file like so:
(supertux-tiles
(tilegroup
(name (_ "Snow"))
(tiles
"7"
)
)
)
Which then compiles fine and the xml is generated upon, but I don't know how to convert all the integers into their string representation, reading from the list. I tried parsing the string and using the write-to-string method but I think I'm missing something.
Any help will be grated.
Thanks!
-- EDIT --
Changing string with princ-to-string as coredump suggested fixes the parsing evaluation of raw numbers within the string, however, when attempting to evaluate symbols such as t this is what it happens:
no dispatch function defined for #\T
using as an example the following
(tile
; dupe of tile 70, this one will be removed.
(id 63)
(deprecated #t)
(images
"tilesets/background/backgroundtile1.png"
)
)
It looks, though, that evaluating to a variable outside Lisp will be kept by only checking for the "t" xml tag.
This got solved.
A quick search on google lead to the following repository (https://github.com/Vifon/sexp-to-xml/blob/master/sexp-to-xml.lisp); the linked code is enough to reproduce the error. Note that when I run it from inside Emacs/Slime, the debugger shows the backtrace:
0: (STRING 7)
1: (SEXP-TO-XML--INSIDE-TAG (7 8 9 202 13 14 ...))
2: (SEXP-TO-XML--NEW-TAG (TILES 7 8 9 202 13 ...))
3: (SEXP-TO-XML--INSIDE-TAG ((TILES 7 8 9 202 13 ...)))
4: (SEXP-TO-XML--INSIDE-TAG ((NAME (_ "Snow")) (TILES 7 8 9 202 13 ...)))
5: (SEXP-TO-XML--NEW-TAG (TILEGROUP (NAME (_ "Snow")) (TILES 7 8 9 202 13 ...)))
6: (SEXP-TO-XML--INSIDE-TAG ((TILEGROUP (NAME #) (TILES 7 8 9 202 13 ...))))
7: (SEXP-TO-XML--NEW-TAG (SUPERTUX-TILES (TILEGROUP (NAME #) (TILES 7 8 9 202 13 ...))))
8: (SEXP-TO-XML-UNQUOTED (SUPERTUX-TILES (TILEGROUP (NAME #) (TILES 7 8 9 202 13 ...))))
Pressing v on various stack frames listed above, I can locate the places where the code currently is halted across the call stack.
I did not load a lisp file, but just evaluated the different forms in the current Emacs buffer, so there is no source file associated with functions. Yet, the AST form is stored for debugging purposes and the debugger can pinpoint where code execution currently is, wrapped in a fake (#:***HERE*** ...) form:
(SB-INT:NAMED-LAMBDA SEXP-TO-XML--INSIDE-TAG
(SEXP)
(BLOCK SEXP-TO-XML--INSIDE-TAG
(IF SEXP
(IF (LISTP (CAR SEXP))
(PROGN
(SEXP-TO-XML--NEW-TAG (CAR SEXP))
(SEXP-TO-XML--INSIDE-TAG (CDR SEXP)))
(PROGN
(PUSH (FORMAT-TAG (#:***HERE*** (STRING (CAR SEXP)))) *OUTPUT*)
(SEXP-TO-XML--INSIDE-TAG (CDR SEXP)))))))
Calling string on arbitrary values won't work, you need to replace that by princ-to-string in sexp-to-xml--inside-tag. Then it works as expected.

validate moves and move pieces on the board in Lisp

because don´t return nothing and show nothing
what I´m doing wrong?
Let's take a look at the validation function. First, make sensible limebreaks: when a multiline form is closed, break the line.
(defun validate-movements (x y board)
"Function that receives two indexes and board to validate movement"
(cond ((and
;; validation of rows and columns
(>= x 0)
(>= y 0)
(<= x 9)
(<= y 9)
(= (apply '+
(mapcar (lambda (L)
(cond ((atom L) 0)
((or (not (equal (nth 0 L ) x))
(not (equal (nth 1 L) y)))
0)
(T 1)))
board))
0))
0)
(T nil )))
A condition that has only two possible outcomes is better handled through if:
(defun validate-movements (x y board)
"Function that receives two indexes and board to validate movement"
(if (and
;; validation of rows and columns
(>= x 0)
(>= y 0)
(<= x 9)
(<= y 9)
(= (apply '+
(mapcar (lambda (L)
(cond ((atom L) 0)
((or (not (equal (nth 0 L ) x))
(not (equal (nth 1 L) y)))
0)
(T 1)))
board))
0))
0
nil))
Comparators like <= can take more arguments:
(defun validate-movements (x y board)
"Function that receives two indexes and board to validate movement"
(if (and (<= 0 x 9)
(<= 0 y 9)
(= (apply '+
(mapcar (lambda (L)
(cond ((atom L) 0)
((or (not (equal (nth 0 L) x))
(not (equal (nth 1 L) y)))
0)
(T 1)))
board))
0))
0
nil))
Since your board is a list of lists (one 10-element sublist per line), a line will never be an atom:
(defun validate-movements (x y board)
"Function that receives two indexes and board to validate movement"
(if (and (<= 0 x 9)
(<= 0 y 9)
(= (apply '+
(mapcar (lambda (L)
(cond ((or (not (equal (nth 0 L) x))
(not (equal (nth 1 L) y)))
0)
(T 1)))
board))
0))
0
nil))
Again, a two-clause conditional is better an if:
(defun validate-movements (x y board)
"Function that receives two indexes and board to validate movement"
(if (and (<= 0 x 9)
(<= 0 y 9)
(= (apply '+
(mapcar (lambda (L)
(if (or (not (equal (nth 0 L) x))
(not (equal (nth 1 L) y)))
0
1))
board))
0))
0
nil))
Now, I wanted to tell you how booleans are much easier to express logic with. However, that condition makes no sense to me: you seem to check that there is some line on the board that carries the x coordinate in its first field and the y coordinate in the second.
Maybe you wanted to check that the target coordinate is empty?
(defun target-valid-p (x y board)
(and (<= 0 x 9)
(<= 0 y 9)
(null (nth x (nth y board)))))
Next, the move function. Again, linebreaks:
(defun move-piece (x y dx dy board)
"Function that receives two indexes and board to move the piece on the board"
(mapcar (lambda (L)
(cond
((atom L) L)
((and (equal (nth 0 L) x)
(equal (nth 1 L) y))
(list (+ (nth 0 L) dx) (+ (nth 1 L) dy) (nth 2 L)
(nth 3 L) (nth 4 L) (nth 5 L) (nth 6 L)
(nth 7 L) (nth 8 L) (nth 9 L)))
(T L)))
board))
Your lines are never atoms:
(defun move-piece (x y dx dy board)
"Function that receives two indexes and board to move the piece on the board"
(mapcar (lambda (L)
(cond
((and (equal (nth 0 L) x)
(equal (nth 1 L) y))
(list (+ (nth 0 L) dx) (+ (nth 1 L) dy) (nth 2 L)
(nth 3 L) (nth 4 L) (nth 5 L) (nth 6 L)
(nth 7 L) (nth 8 L) (nth 9 L)))
(T L)))
board))
Two-branch conditional is if:
(defun move-piece (x y dx dy board)
"Function that receives two indexes and board to move the piece on the board"
(mapcar (lambda (L)
(if (and (equal (nth 0 L) x)
(equal (nth 1 L) y))
(list (+ (nth 0 L) dx) (+ (nth 1 L) dy) (nth 2 L)
(nth 3 L) (nth 4 L) (nth 5 L) (nth 6 L)
(nth 7 L) (nth 8 L) (nth 9 L))
L))
board))
Use list* and nthcdr to update part of a list:
(defun move-piece (x y dx dy board)
"Function that receives two indexes and board to move the piece on the board"
(mapcar (lambda (L)
(if (and (equal (nth 0 L) x)
(equal (nth 1 L) y))
(list* (+ (nth 0 L) dx)
(+ (nth 1 L) dy)
(nthcdr 2 L))
L))
board))
Now it seems that you again just update the first two cells of the line. Maybe I didn't understand your data model, but I would have thought that you just want to update the cells at the given coordinates:
(defun move-piece (x y dx dy board)
(let ((new-board (copy-tree board))
(new-x (+ x dx))
(new-y (+ y dy))
(piece (nth x (nth y board))))
(setf (nth x (nth y new-board)) nil
(nth new-x (nth new-y new-board)) piece)
new-board))

Sorting entries in emacs diary file

I use emacs diary.
As I append both future plans and daily review in the diary file,
the entries in the file results in not following chronological order.
When I review the diary file at some occasion, I would like to have these entries sorted.
Is there any commands or lisp that I can use to modify the diary file so that the entries get sorted in the chronological order?
A long time ago, I wrote myself a sort function:
(defun diary-sort-diary-keyfun nil
"Key function to order diary entries.
Entries sort in the groups: (days, anniversaries, cyclics, blocks, dates), with any unrecognised
forms before the groups.
Within each group, entries are in ascending date order.
You can prefix entries with `#' to comment them out without affecting sort order.
Prefixing with `&' also does not affect sort order."
(let ((number "\\s-+\\([0-9]+\\)")
(months '("Dec" "Nov" "Oct" "Sep" "Aug" "Jul" "Jun" "May" "Apr" "Mar" "Feb" "Jan"))
(days '("Saturday" "Friday" "Thursday" "Wednesday" "Tuesday" "Monday" "Sunday")))

It's likely that I've assumed European date order, but if you prefer a different order, it shouldn't be hard to adapt it accordingly.
The way it works is that the keyfun returns a string that begins with two digits for the entry type (00 for unknowns, 10 for day-of-week entries, up to 60 for non-repeating dates), followed by a big-endian representation of the entry, like ISO 8601.
The interactive function, diary-sort-diary-file, then uses this keyfun. It saves any Local variables section, reinstating it at the end of the file (this is nice when you've inserted entries from calendar, as they get appended). If you have any LocalWords lines (for Ispell), then you could use similar code to keep that intact, or you could adapt the keyfun to place them last.

In icalendar.el, function icalendar--datetime-to-iso-date, change format from "%d%s%d%s%d" to "%04d%s%02d%s%02d".
Add this to your initialization:
(setq
diary-date-forms diary-iso-date-forms
calendar-date-style 'iso
)
Edit old entries in your diary-file to the ISO standard, formatted as above, i.e YYYY/MM/DD. (The ISO standard is really YYYY-MM-DD).
Now further add this to your initialization:
(defun sort--diary (diary-filename)
(with-current-buffer
(set-buffer (find-file-noselect (expand-file-name diary-filename)))
(goto-char (point-min))
(while (search-forward "\C-j " nil t)
(replace-match "^j "))
(sort-lines nil (point-min) (point-max))
(goto-char (point-min))
(while (search-forward "^j" nil t)
(replace-match "\C-j"))
(save-buffer)))
(defvar sort--diary-filename (expand-file-name diary-file)
"History for sort--diary diary-filename")
(defun sort-diary (diary-filename)
"Sort diary file. Requires dates to use ISO standard"
(interactive (list (read-from-minibuffer
"diary file name: "
(car sort--diary-filename)
nil nil 'sort--diary-filename)))
(sort--diary diary-filename))
Now you can sort your diary by calling sort-diary.

How to print a list as matrix in Common Lisp

I am working in Common Lisp, trying to make Windows game minesweeper.
I have a list (1 1 1 2 2 2 3 3 3) and want to print that like matrix
(1 1 1
2 2 2
3 3 3)
How to do that?
Edit
I am at the beginning of
(format t "Input width:")
(setf width (read))
(format t "Input height:")
(setf height (read))
(format t "How many mines:")
(setf brMina (read))
(defun matrica (i j)
(cond ((= 0 i) '())
(t (append (vrsta j) (matrica (1- i) j) ))))
(setf minefield (matrica width height))
(defun stampaj ()
(format t "~%~a" minefield ))
Another example, using the pretty-printer for fun:
(defun print-list-as-matrix
(list elements-per-row
&optional (cell-width (1+ (truncate (log (apply #'max list) 10)))))
(let ((*print-right-margin* (* elements-per-row (1+ cell-width)))
(*print-miser-width* nil)
(*print-pretty* t)
(format-string (format nil "~~<~~#{~~~ad~~^ ~~}~~#:>~%" cell-width)))
(format t format-string list)))
Works like this:
CL-USER> (print-list-as-matrix (loop for i from 1 to 9 collect i) 3)
1 2 3
4 5 6
7 8 9
NIL
CL-USER> (print-list-as-matrix (loop for i from 1 to 25 collect i) 5)
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
NIL
CL-USER> (print-list-as-matrix (loop for i from 1 to 16 collect i) 2)
1 2
3 4
5 6
7 8
9 10
11 12
13 14
15 16
Like this:
(defun print-list-as-grid (list rows cols)
(assert (= (length list) (* rows cols))
(loop for row from 0 below rows do
(loop for col from 0 below cols do
(princ (car list))
(princ #\space)
(setf list (cdr list)))
(princ #\newline)))
* (print-list-as-grid '(a b c d e f g h i) 3 3)
A B C
D E F
G H I
NIL
