Today I had to create an easy maintainable link-list inside an FCE. As TYPO3 does not offer any native link-lists, you have to make it yourself. Well after some time and try-out I got something working, and a beer from Steffen (thank you very much). It works similar to the tt_content.bullets, just that in this case each line contains a text and where it links, like this:

Title | http://google.com - - Google
Title | http://wikipedia.org - - Wikipedia

You may recognize it’s just a text and a complete typolink-parameter. Easy enough - you think. Well take a look and decide if you’ve made the same.

Here is the code (public domain):

10 = TEXT
10.field = field_links
10.wrap =
|

10 {
	trim = 1
	split {
		token.char = 10
		cObjNum = 1

		1.parseFunc >

		# the negative match has to be done first, because the
		# following split actually changes the current-value
		1.1 = TEXT
		1.1.current = 1
		1.1.wrap =
|

		1.1.if.value.current = 1
		1.1.if.matches = /\|/
		1.1.if.negate = 1

		# continue with destructive splitting
		1.2 = TEXT
		1.2.current = 1
		1.2.wrap =
|

		1.2.if.value.current = 1
		1.2.if.matches = /\|/

		1.2.trim = 1
		1.2.split {
				token = |
				cObjNum = |*|1||2|*|

				# we don’t put the string into value, so we would not need to delete it
				# if we would delete it with ‘>’, the LOAD_REGISTER will not work
				1.parseFunc >
				1.1 = LOAD_REGISTER
				1.1.title.current = 1

				# we don’t put the string into value, so we don’t overwrite 2.1
				# if we would overwrite 2.1, the RESTORE_REGISTER will kill all data
				2.parseFunc >
				2.2 = RESTORE_REGISTER
				2.trim = 1

				# so this is it, first fragment into value, second directly into typolink
				# the order of execution is sorted, so don’t worry about the strange order here
				2.1 = TEXT
				2.1.data = register:title
				2.typolink {
					parameter.current = 1
					ATagParams = rel=”shadowbox”
					target =
					extTarget =
				}
		}
	}
}

Most often, when you search something extremly simple and obvious, you have a hard time finding it. The simpler and the more obvious, the harder. This time I wanted to send a listing of a directory structure per email, no complex content, no HTML no Doc (how again do you export directory-trees directly into a graphic or document?).

Here is the result (public domain):

#!/bin/bash

target=.
prefix=
last=

if test $# -gt 0; then
  target="$1"
fi
if test $# -gt 1; then
  prefix="$2"
fi

for sub in "$target"/*; do
   if test -f "$sub"; then
      num=$(ls -1 "$sub" | wc -l)
      if [ $num -gt 0 ]; then
         last=”$sub”
      fi
   fi

   if test -d “$sub”; then
      num=$(ls -1 “$sub” | wc -l)

         echo “$prefix” \+- ${sub#$target\/}
      fi
      if [ "$last" = "$sub" ]; then
         echo “$prefix” \`- ${sub#$target\/}
      fi
   fi
done

for sub in “$target”/*; do
   if test -d “$sub”; then
      num=$(ls -1 “$sub” | wc -l)
      if [ $num -gt 0 ]; then
         echo “$prefix” \|

         if [ "$last" != "$sub" ]; then
            echo “$prefix” \+- ${sub#$target\/}
            echo “$prefix” \|\ \ \|
            treef “$sub” “$prefix | ”
         fi
         if [ "$last" = "$sub" ]; then
            echo “$prefix” \`- ${sub#$target\/}
            echo “$prefix” \ \ \ \|

If you got faster variatoins of this quick hack fitting my needs, I’m going to update the code with your suggestions. Here BTW is an example of the output:
