* view, vfilter: Add support for filtering tags and values out of a view, ↵Gravatar Joey Hess2014-03-02
| | | | | | | | | | using !tag and field!=value. Note that negated globs are not supported. Would have complicated the code to add them, without changing the data type serialization in a non-backwards-compatable way. This commit was sponsored by Denver Gingerich.
* views: add automatically constructed file location metadataGravatar Joey Hess2014-02-22
| | | | | | | | | | | | | | | | | | | | | | | When constructing views, metadata is available about the location of the file in the view's reference branch. Allows incorporating parts of the directory hierarchy in a view. For example `git annex view tag=* podcasts/=*` makes a view in the form tag/showname. Performance impact: I benchmarked git annex view tag=* in the conference proceedings repo to take 6.459s before this change, and 6.544s after. FWIW, I considered making the syntax for this be podcasts/*, which might be easier for the user to learn. However, I think it's not as good: * The user has to then juggle two different syntaxes, and podcasts/* will be expanded by the shell so they also need to quote it, while podcasts/=* is unlikely to be expanded by the shell. * It would allow for things like podcasts/*/* and *.mp3 which do not map well into views.

* add tip about metadata driven views (and more flexible view filtering)Gravatar Joey Hess2014-02-19
| | | | | | | | | | | | | | | | | | | | | | While writing this documentation, I realized that there needed to be a way to stay in a view like tag=* while adding a filter like tag=work that applies to the same field. So, there are really two ways a view can be refined. It can have a new "field=explicitvalue" filter added to it, which does not change the "shape" of the view, but narrows the files it shows. Or, it can have a new view added, which adds another level of subdirectories. So, added a vfilter command, which takes explicit values to add to the filter, and rejects changes that would change the shape of the view. And, made vadd only accept changes that change the shape of the view. And, changed the View data type slightly; now components that can match multiple metadata values can be visible, or not visible.
