Bug ID: 456846
Summary: Kate Snippets: not clear how to work with selected
text
Product: kate
Version: 22.04.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: plugin-snippets
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
The docs for Snippets could use some love:
https://docs.kde.org/trunk5/en/kate/kate/kate-application-plugin-snippets.html
I am looking for a way to wrap the selected text in tags, for example to help
with MediaWiki Translate extension. Searching all over the web, I found many
others looking for the same information.
There is an old blog post with relevant discussion in the comments:
https://milianw.de/blog/snippets-in-kdevelop-kate.html
It is said that at some point this used to work:
<strong>%{selection}</strong>
There is a function in the view API view.selectedText() but it does not seem to
be applying or maybe I am missing something.
https://docs.kde.org/trunk5/en/kate/katepart/dev-scripting.html#dev-scripting-api
Given this in the Snippet tab
<translate>${text}</translate>
and in the Scripts tab
text = view.selectedText();
the variable will be simply be replaced by "text".
I also tried with editor.clipboardText() but the result was still "text", which
I don't understand at all.
If I use the percentage sign instead of dollar sign, like %{text}, the result
will just be %{text}.
I found this doc from 2010 that explains the difference between $ and %
variables: https://kate-editor.org/2010/02/03/snippets-in-kdevelop-kate/
"snippet gets inserted (properly indented) and potential placeholders/variables
get expanded. A variable is something like %{date} or ${email}. Also take a
look at the API documentation.
variables that get inserted via “${…}” will be “selectable”, meaning you can
jump from one var to the other by hitting TAB / Shift TAB
the %{…} vars will only get expanded and inserted, without getting selectable."
