ecb-methods-filter-nofilter allows to filter the tags/nodes of
the Methods-buffer by several criterias. As for the Sources- and the
History-buffer the same functionality is also available via the
popup-menu of the Methods-buffer.
ecb-methods-filteroffers only the tag-classes of the current mode. This means for sources not supported by semantic the tag-class filter will not be offered. And for semantic-supported sources exactly these tag-classes are offered the semantic-parser for the current major-mode offers. For example texi-sources can only be filtered by the tag-classes “Definitions” and “Sections” and java-sources can be filtered by “Methods”, “Variables”, “Classes” etc. In general the semantic-variable
semantic-symbol->name-assoc-listis used to get the right tag-classes.
ecb-show-tokens. If currently some of the above filters are applied they will be all removed.
Be aware that the tag-list specified by the option
ecb-show-tags is the basis of all filters, i.e. tags which are
excluded by that option will never be shown regardless of the filter
All tags which match the applied filter(s) will be displayed in the Methods-buffer. Such a filter is only applied to the current source-buffer, i.e. each source-buffer can have its own tag-filters.
These tag-filters can also applied to sources which are not supported by the semantic-parser but “only” by imenu or etags. But because for these sources not all information are avaiable the protection- and tag-class filter are not offered with such “non-semantic”-sources. See Non-semantic sources for further details about working with source-files not supported by the semantic-parser.
ecb-methods-filter is called with a prefix-argument then
an inverse filter is applied to the Methods-buffer, i.e. all tags
which do NOT match the choosen filter will be displayed in
Per default the choosen filter will be applied on top of already
existing filters. This means that filters applied before are combined
with the new filter. This behavior can changed via the option
The current active filter will be displayed in the modeline of the Methods-buffer [regexp, prot (= protection), tag-class, function (= filter-function)]. If an inverse filter has been applied then this is signalized by a preceding caret ^. If currently more than 1 filter is applied then always the top-most filter is displayed in the modeline but the fact of more than 1 filter is visualized by the number of the filters - included in parens. You can see all currently applied filters by moving the mouse over the filter-string in modeline of the Methods-buffer: They will displayed as help-echo.
The new option
ecb-default-tag-filter allow to define default
tag-filters for certain files which are applied automatically after
loading such a file into a buffer. The possible filters are the same
as offered by the command
ecb-methods-filter and they are
applied in the same manner - the only difference is they are applied
automatically. The files can be specified on a combined major-mode-
Usage-example: This can be used to display in outline-mode files (e.g. NEWS) only the level-1-headings by defining a filter regexp “^\* .*”.
