"Custom formats for individual tags.
|
|
|
|
This gives a list that maps from tag names to lists of formatting
|
|
expressions. The car of each element gives a tag name and the
|
|
cdr gives a list of Elisp expressions that modify the tag. If
|
|
the list is empty, the tag will simply be hidden. Otherwise,
|
|
each expression will be evaluated in order: for the first
|
|
expression, the variable `tag' will be bound to the tag name; for
|
|
each later expression, the variable `tag' will be bound to the
|
|
result of the previous expression. In this way, each expression
|
|
can build on the formatting performed by the previous expression.
|
|
The result of the last expression will displayed in place of the
|
|
tag.
|
|
|
|
For example, to replace a tag with another string, simply use
|
|
that string as a formatting expression. To change the foreground
|
|
of a tag to red, use the expression
|
|
(propertize tag 'face '(:foreground \"red\"))
|
|
|
|
See also `notmuch-tag-format-image', which can help replace tags
|
|
with images."
