simple template replacement

Post by tomtoo »

Howdy guys,

I want to label a text file with something like, ",1," ",2," etc, and
copy what follows the 1 to what precedes the 2, etc, then stick it into
corresponding spot in a template.

There are regular expressions and junk in there I'm not too
comfortable with, so I thought I'd rather ask than struggle.
:-)

Hmm a bit too vague there...! You'd probably need to supply sample source data and stuff. But some thoughts:

Code: Select all

(set 'text {foo foo ,1, bar bar ,2, baz baz ,3,})
(find-all {(.*?),1,} text)
Here $1 now contains the first match of the parenthesized term - foo foo.

To move stuff around, you can try rebuilding the target string from the components you found.

Code: Select all

(set 'text {foo foo ,1, bar bar ,2, baz baz ,3,})
(replace {(.*?),1,(.*?),2,(.*?)} text (string $3 $2 $1) 0)
(println text)
;->  bar bar foo foo  baz baz ,3,

sorry about that.

Code: Select all

,1,
Heading
,2,
paragraph paragraph paragraph paragraph paragraph 
paragraph paragraph paragraph paragraph paragraph 
paragraph paragraph paragraph paragraph paragraph 

,3,
listitem
,4,
listitem
,5,
nested listitem

,6,
paragraph paragraph paragraph paragraph paragraph 
paragraph paragraph paragraph paragraph paragraph 
Is that better?

I'd like to write a plain old text file and not have to worry about the mark-up, or worse, some mark-up helper that's just as bad. This seems simple to me. maybe better than the comma-digit-comma thing would just be the digit on a line by itself.

The output I have in mind are pdfs or whatever via latex.

Thanks!

I'm not convinced I understand what you mean - unless you just want to sort the different sections of the file according to the number that 'precedes' them...? (because "copy what follows the 1 to what precedes the 2," doesn't seem to do much...).

If that's what you want, though, here's a script that sorts a file based on what you define as a section divider:

Code: Select all

(set 'l (parse (read-file ((main-args) 2)) "\n" 0)) ; or whatever reads the file

(set 'temp-store '() 'section '())

(define (new-section? lst lmnt)
   (if (starts-with (lst lmnt) ",\\d," 0))) ;-< section starts with ,1, ,2, etc.

(for (i 0 (- (length l) 1))
   (when (new-section? l i)
       (push section temp-store -1)
       (set 'section '()))
   (push (l i) section -1))

(push section temp-store -1)
(sort temp-store)
(print (join (flat (clean empty? temp-store)) "\n"))
(exit)

Hi guys,

this thing I have more or less working only correctly makes ten replacements. can you see what's wrong?

               ))

(define (c cc)
  (set (sym (cc 0)) (cons (cc 1) '())))

(map c box)


(set 'a (read-file "bb.html"))

(dolist (item e)

hmm, some wild code there.

Edit: I think I see what you're doing now. It's doing 12 for me. Because the length is 12... ?

The replace loop replaced 1= and 2= before it does 11= and 12=

It sees the embedded 1= in 11= and 2= in 12= and replaces it after it does the original 1= and 2=

Use a more unique looking tag, something like =1= =2= ... =11= =12= etc...

P.S. Interesting use for transpose I had never thought of... Lutz, should this be documented? Or is there a better function to use for a string matrix? Or should a flag be added to transpose to prevent floating point conversion in these cases?

yeah, pretty wild. I often hesitate to "show off" just because it's so dang ugly...

I get 12 replacements but only 10 correct replacements. For 11 and up it replaces from somewhere in the first ten.

Perhaps check those regex/find things. Perhaps "2=" is found twice, once in 2= once in 12=...?

I like wild code... :0

Since version 7.4.8 'transpose' handles any data type and it only re-arranges data. There is no transformation from integers to floats anymore when transposing matrices containing numbers. The documentation fixes this for 10.2:

Thanks guys, that did the trick. originally, the tags were ",1," and I changed them to "1=". I changed them back. :-)
