"*Function to use for displaying tags in the methods buffer.
This functionality is set on major-mode base, i.e. for every major-mode a
different function can be used. The value of this option is a list of
cons-cells:
- The car is either a major-mode symbol or the special symbol 'default which
means if no function for a certain major-mode is defined then the cdr of
the 'default cons-cell is used.
- The cdr is the function used for displaying a tag in the related
major-mode.
Every function is called with 3 arguments:
1. The tag
2. The parent-tag of tag \(can be nil)
3. The value of the function `ecb-font-lock-tags'.
Every function must return the display of the tag as string, colorized if
the third argument is not nil.
The following functions are predefined:
- For each element E of `ecb--semantic-format-function-list' exists a
function with name \"ecb--<E>\". These functions are just aliase to
the builtin format-functions of semantic. See the docstring of these
functions to see what they do.
Example: `semantic-format-tag-name' is an
element of `ecb--semantic-format-function-list'. Therefore the
alias-function for this element is named `ecb--semantic-format-tag-name'.
- For each element in `ecb--semantic-format-function-list' with name
\"semantic-XYZ\" a function with name \"ecb-XYC\" is predefined. The
differences between the semantic- and the ECB-version are:
+ The ECB-version displays for type tags only the type-name and nothing
else \(exceptions: In c++-mode a template specifier is appended to the
type-name if a template instead a normal class. If the tag-name of a
type-tag is the empty-string \(tag has no name) then always the
type-specifier is displayed - see `ecb-type-tag-display'.).
+ The ECB-version displays type-tags according to the setting in
`ecb-type-tag-display'. This is useful for better recognizing
different classes, structs etc. in the ECB-method window.
For all tags which are not types the display of the ECB-version is
identical to the semantic version. Example: For
`ecb--semantic-format-tag-name' \(the builtin semantic formatter) the
pendant is `ecb-format-tag-name'.
This functionality also allows the user to display tags as UML. To enable
this functionality set the function for a major-mode \(e.g. `jde-mode') to
`ecb--semantic-format-tag-uml-concise-prototype',
`ecb--semantic-format-tag-uml-prototype', or
`ecb--semantic-format-tag-uml-abbreviate' the ECB-versions of these functions.
If the value is nil, i.e. neither a function for a major-mode is defined nor
the special 'default, then `ecb--semantic-format-tag-prototype' is used for
displaying the tags.

"*How to display semantic type-tags in the methods buffer.
Normally all tag displaying, colorizing and facing is done by semantic
according to the value of `ecb--semantic-format-face-alist' and the semantic
display-function \(e.g. one from `ecb--semantic-format-function-list'). But
sometimes a finer distinction in displaying the different type specifiers of
type-tags can be useful. For a description when this option is evaluated look
at `ecb-tag-display-function'!
This functionality is set on a major-mode base, i.e. for every major-mode a
different setting can be used. The value of this option is a list of
cons-cells:
- The car is either a major-mode symbol or the special symbol 'default which
means if no setting for a certain major-mode is defined then the cdr of
the 'default cons-cell is used.
- The cdr is a list of 3-element-lists:
1. First entry is a semantic type specifier in string-form. Current
available type specifiers are for example \"class\", \"interface\",
\"struct\", \"typedef\", \"union\" and \"enum\". In addition to these
ones there is also a special ECB type specifier \"group\" which is
related to grouping tags \(see `ecb-post-process-semantic-taglist' and
`ecb-group-function-tags-with-parents'). Any arbitrary specifier can be
set here but if it is not \"group\" or not known by semantic it will be
useless.
2. Second entry is a flag which indicates if the type-specifier string from
\(1.) itself should be removed \(if there is any) from the display.
3. Third entry is the face which is used in the ECB-method window to display
type-tags with this specifier. ECB has some predefined faces for this
\(`ecb-type-tag-class-face', `ecb-type-tag-interface-face',
`ecb-type-tag-struct-face', `ecb-type-tag-typedef-face',
`ecb-type-tag-union-face', `ecb-type-tag-enum-face' and
`ecb-type-tag-group-face') but any arbitrary face can be set here. This
face is merged with the faces semantic already uses to display a tag,
i.e. the result is a display where all face-attributes of the ECB-face
take effect plus all face-attributes of the semantic-faces which are not
set in the ECB-face \(with XEmacs this merge doesn't work so here the
ECB-face replaces the semantic-faces; this may be fixed in future
versions).
The default value is nil means there is no special ECB-displaying of
type-tags in addition to the displaying and colorizing semantic does. But a
value like the following could be a useful setting:
\(\(default
\(\"class\" t ecb-type-tag-class-face)
\(\"group\" nil ecb-type-tag-group-face))
\(c-mode
\(\"struct\" nil ecb-type-tag-struct-face)
\(\"typedef\" nil ecb-type-tag-typedef-face)))
This means that in `c-mode' only \"struct\"s and \"typedef\"s are displayed
with special faces \(the specifiers itself are not removed) and in all other
modes \"class\"es and grouping-tags \(see `ecb-tag-display-function',
`ecb-group-function-tags-with-parents') have special faces and the \"class\"
specifier-string is removed from the display.

"*Functions used for searching external tags clicked in the methods buffer.
The methods buffer displays for oo-languages the parents of a
type under a special bucket \"Parents\". Languages like C++, CLOS
and Eieio allow to define the implementation of a method outside
of the class definition and even in another file. In the
methods-buffer of ECB such externaly defined methods are
collected and displayed under a 'virtual' faux type-tag named as
the class-qualifier of the methods. This faux-tag is virtual
because it does not extist in the parsed buffer.
If a user clicks either onto such a faux-type-tag or onto a
parent-tag then ECB tries to find the definition of the
underlying type on a name-basis, displaying the containing file
as buffer in the current edit-window and jumping to the start of
the type-definition in this buffer.
Finding such external types can be very complex and there are
several roads to success. ECB uses per default methods based on
the semantic-analyzer. But this option allows to define own
find-functions and tell ECB to uses them.
This functionality is set on a `major-mode' base, i.e. for every
`major-mode' a different setting can be used. The value of this
option is a list of cons-cells:
- The car is either a `major-mode' symbol or the special symbol 'default.
- The cdr is a list of find-functions or nil.
ECB first performs all find-functions defined for current
`major-mode' \(if any) anf then all find-functions defined for
the special symbol 'default \(if any).
ECB offers some predefined senseful finding-functions. Currently there are:
- `ecb-search-type-tag-by-semantic-analyzer' (most powerful)
- `ecb-search-type-tag-by-semanticdb'
- `ecb-jde-show-class-source' (for major-mode `jde-mode' when coding in java)
This function does not only the searching but displays the founded tag.
See the documentation of these function for details how they work.
But you can add any arbitrary function if the following conditions are
fulfilled:
- The function gets a semantic tag representing the external type which should
be found. This is a positionless-tag \(otherwise it would not be hard to go
to it) and it's either a faux-tag \(for which `ecb--semantic-faux-tag-p' is
not nil; the function can use this check if necessary) or a simple tag
containing only a name an a tag-class. The tag-class for both is 'type.
- The return value of the function must be one of:
+ nil: No tag is found
+ t: A tag has been found and also be displayed in the edit-window \(this
prevents ECB from running further function of this option because the
searched tag is already displayed. So a function should only return t if
all is fine and no further actions are needed.
+ A positioned semantic tag \(for which `ecb--semantic-tag-with-position-p'
returns not nil) which represents the found external type-tag.
It's strongly recommended for the function not to display the found
location for itself but to return a positioned semantic tag! But sometimes
the displaying is integrated in a third-party find-function like
`jde-show-class-source' which is used by `ecb-jde-show-class-source'. In
these cases the function has to return t if the searched tag has been
successfully displayed.
Precondition for a find-function:
Current buffer is the buffer the clicked faux- or parent tag belongs to
Current point depends on the clicked tag:
- In case of a faux-tag it's the start of the first child of the
faux-tag. There must be at least one adopted child-tag because
otherwise we would not have the faux-tag
- In case of an external parent-tag its the the start of the
external tag itself."

Generally ECB calls semantic to get the list of tags for current source-file
of current edit-window. Per default ECB does never automatically force a
reparse of the source-file - this is only done on demand by calling
`ecb-rebuild-methods-buffer'. So per default the idle-scheduler of semantic is
responsible for reparsing the source-file and when this is necessary \(see
`semantic-idle-scheduler-mode' for further details). This is the most
user-resonsible and therefore the recommended approach. So it's strongly
recommended to enable `semantic-idle-scheduler-mode' because then reparsing is
always done during idle-time of Emacs and is also interruptable.
But if this idle-scheduler is switched off then ECB offers two possibilities
\(with this option):
- Not forcing itself a reparse when tags are needed by ECB: then a user
declines knowingly Emacs/semantic-driven parsing of code when he/she
switches off the idle-mode of semantic. This is the default behavior of ECB
and the default value of this option. But this has also the consequence that
the methods-buffer is only filed on demand via `ecb-rebuild-methods-buffer'
\(bound to \[C-c . r])!
- Forcing a reparse when tags are needed: Then ECB forces semantic to parse
the source-file when ECB needs tags to display. For this behavior this
option has to be set to not nil.
Note 1: This option takes only effect when `semantic-idle-scheduler-mode' is
not enabled!
Note 2: The term \"forcing a reparse by semantic\" is a simplification:
It uses the function `semantic-fetch-tags' which can decide that the cached
tags are up-to-date so no real reparsing is necessary - but it can also run a
full reparse and this reparse is not being done when Emacs is idle but
immediatelly and not interruptable \(as with the idle-scheduler of semantic)!"

'collapsed. See also `ecb-methods-separate-prototypes'.
The tags in the methods buffer are displayed in the order as they appear in
this list.
Tag Type
----------
A Semantic tag type symbol \(for all possible type symbols see documentation
of semantic):
- include
- type
- variable
- function
- rule
- section \(chapters and sections in `info-mode')
- def \(definitions in `info-mode')
or one of the following:
- t: All tag types not specified anywhere else in the list.
- parent: The parents of a type.
Display Type
------------
A symbol which describes how the tags of this type shall be shown:
- expanded: The tags are shown in an expanded node.
- collapsed: The tags are shown in a collapsed node.
- flattened: The tags are added to the parent node.
- hidden: The tags are not shown.
Sort Method
-----------
A symbol describing how to sort the tags of this type:
- name: Sort by the tag name.
- access: Sort by tag access (public, protected, private) and then by name.
- nil: Don't sort tags. They appear in the same order as in the source
buffer.

the prototypes from the real function/methods. Then with `ecb-show-tags' the
user can define different display-settings for each of them. If this option is
nil then the prototypes and the real functions are filled in the same bucket
and displayed plain and there is no sorting between prototypes and functions
possible. If this option is switched on then it is senseful that

There are three different choices:
- 'never: This is the default and means that calling `ecb-methods-filter'
always adds the new filter on top of already existing filters. So you can
combine several filter to one combined like this example: 'Display only all
public methods having the string \"test\" in its name.' With this setting
the filters can only be cleared by calling `ecb-methods-filter' and then
choosing \"nothing\".

filter before applying the new one.

The value of this option is either the symbol 'all \(all tags are expanded
regardless of their type) or a list of symbols where each symbol is a valid
semantic tag-type. For a description of semantic tag types see option
`ecb-show-tags'.
But this option also defines if bucket-nodes in the ECB-method-buffer \(e.g.
\"\[Variables\]\") should be expanded. Therefore valid symbols for this list
are also all cars of the variable `semantic-symbol->name-assoc-list'.
If there is a bucket-name \(the node-name stripped of the settings in
`ecb-bucket-node-display') which is not contained as cdr in
`semantic-symbol->name-assoc-list' then the symbol with this bucket-name as
name is also a valid symbol for this list. Example: In ECB there are buckets
\"\[Parents\]\". The bucket-name is \"Parents\" and the valid symbol-name is
then 'Parents.
