Hi,

I don't know if this is the correct place to announce and post a new plugin... but here is mine.


The "Insert snippet" plugin adds a new menu entry "Insert/Text from page..." which shows a dialog box where you can enter some page path. Then, its content is added to the current edited page.

Current options are :
- remove title (from inserted text)
- increase header level (h1 goes h2, etc)
- insert backlink to source (above and/or under the inserted text)
- show full namespace (by default, only the basename will be shown)
- add some prefix before backlink (something like "**source : **")

It has been tested on zim 0.49 (Ubuntu)

I hope this can be useful.

PS :
- I can provide french gettext messages for translation
- you're welcome to fix incorrect english words in the plugin...

Best regards,
Pascal

I would like a plugin to reuse text snippets from some other pages.

Example : I create a page "my text templates" and set this as snippets
root in the plugin preferences.

I tried to create such a plugin, but I didn't find how to add zim
formatted text to the current insert point (textview/textbuffer).

Could you give me some advice ?
To insert formatted text you need to parse the text first in order to
get a "parse tree", then you can use the "insert_parsetree_at_cursor"
method. You can get a parsetree for a page with "get_parsetree" or use
the parser for the specific format (default wiki format most likely).

To parse a piece of text and insert it in the current page the plugin
would need to do the following ("self" being the plugin object and
"text" the snippet):

import zim.formats

format = zim.formats.get_format('wiki')
parser = format.Parser()
parsetree = parser.parse(text)

buffer = self.ui.mainwindow.pageview.view.get_buffer()
buffer.insert_parsetree_at_cursor(parsetree)
<<<<<

Hope this helps,

Jaap
