bonjour Yves,
yes, Textallion is still alive (I'm using it almost every day). Last release and
commits are from last november, but I have some more to commit soon
(mostly custom templates for easing the publishing to a page size
different from A4)
There isn't yet a convenient editor for
handling textallion/txt2tags syntax. The closest I can get is an online
editor which can use txt2tags (with some writing guide with clickable
buttons), and you can export to latex or xetex with one-click:
https://bitbucket.org/farvardin/lionwiki-t2t/There is a demo there:
http://wiki.txt2tags.org/demos/lionwiki-t2tIn
this demo you can't export to latex because it's not installed on this
server, but it's possible to do on your own server / computer. For the
record, I've made a huge document of more than 100 pages using this, we
can enter data using the wiki (so several people can use it at the same
time), and we gather all the pages in the final textallion document,
which can be exported on the fly in latex (or xetex) and then in pdf.
The
downside is while editing you only get plain text, without some sort of
syntax highlight. If there is one day a txt2tags renderer in
javascript, maybe it would be possible to edit your txt2tags/textallion
documents like this:
http://nicedit.com/But you can also edit only some sections of the document.
For your last question, I don't think it's possible to interrupt like this numbered lists.
some text (or section title)
+ item 1
+ item 2
some text (or section title)
+ item 3
will work but the "some text" below the first part of the list will be aligned to it, and it will display:
some text (or section title)
1. item 1
2. item 2
some text (or section title) (with extra margin)
3.item 3
You can add an extra space after the first part of the list:
some text (or section title)
+ item 1
+ item 2
some text (or section title)
+ item 3
but then item 3 will start again from 1 :
some text (or section title)
1. item 1
2. item 2
some text (or section title) (no extra margin)
1.item 3
It's a limitation of txt2tags I guess.
