[incubator-annotator] branch css-selector updated (61aec4d ->
f375738)
This is an automated email from the ASF dual-hosted git repository.
gerben pushed a change to branch css-selector
in repository https://gitbox.apache.org/repos/asf/incubator-annotator.git.
discard 61aec4d Add describeCss & tests
new f375738 Add describeCss & tests
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (61aec4d)
\
N -- N -- N refs/heads/css-selector (f375738)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 1 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.

[incubator-annotator] 01/01: Add describeCss & tests
Posted by ge...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
gerben pushed a commit to branch css-selector
in repository https://gitbox.apache.org/repos/asf/incubator-annotator.git
commit f375738cdb0f4a1f369bb49f91b23c1dbc5f396e
Author: Gerben <ge...@treora.com>
AuthorDate: Tue May 25 00:59:21 2021 +0200
Add describeCss & tests
- css-selector-generator gives an error when a scope is passed..
- using @mdev/finder instead gave syntax errors due to ‘export’ token.
May be worth trying to fix?
Should we stop our insistence on Ranges both for scopes and matches?
Makes little sense for CssSelector.
