[pollen] Re: How to create a tag whose content is modified before rendering?

2018-01-20 Thread clozach
Oops! Never mind. I was just missing a pair of parentheses around the 
`default-tag-function`.

Solution (*pollen.rkt*)
















*#lang racket/base(require pollen/tag  racket/string  txexpr  
pollen/decode)(provide (all-defined-out))(define (title text) 
((default-tag-function 'book-title) (string-join (list " " 
text(define (root . items)  (decode (txexpr 'root '() items)  
#:txexpr-elements-proc decode-paragraphs  #:exclude-tags '(style 
script)))Sorry for the distraction. *

[pollen] How to create a tag whose content is modified before rendering?

2018-01-20 Thread clozach
*How can I achieve the Desired Output as shown below?*

I think I'm running into an issue with `define`. According to the docs, 
there are two forms of `define`, one which binds to the result of an 
expression, and the other to a procedure. It seems as if the 2nd, 
parameter-taking form is somehow stirpping the default-tag-function of its 
tag. How can I preserve the `txexpr` generated by `default-tag-function`?

Input (*test.poly.pm*)
#lang pollen

Joan Didion called Joseph Conrad's ◊title{Victory}, "maybe my favorite book 
in the world."

Input (*pollen.rkt*)















*#lang racket/base(require pollen/tag  racket/string  txexpr  
pollen/decode)(provide (all-defined-out))(define (title text) 
(default-tag-function 'book-title) (string-join (list " " text)))(define 
(root . items)  (decode (txexpr 'root '() items)  
#:txexpr-elements-proc decode-paragraphs  #:exclude-tags '(style 
script)))*Actual Output (*test.html*)


  
  : 
  


Joan Didion called Joseph Conrad's   Victory, "maybe my favorite 
book in the world."



Desired Output (*test.html*)


  
  : 
  


Joan Didion called Joseph Conrad's   Victory
, "maybe my favorite book in the world."
