Module tf.advanced.options

Display Settings.

Display options are used by

tf.advanced.display.plain

and

tf.advanced.display.pretty

and other display functions.

This class manages

  • the provisining of options with defaults,
  • the overriding options by passing options as arguments to display functions
  • the retrieval of option values by the rest of the application.

distinction between interface options and display options

  • all interface options are also display options and can be passed as arguments to display functions
  • interface options have a checkbox in the TF browser

Parameters

baseTypes : string | iterable, optional `None``
interface option Node types at the bottom of pretty displays. The default is app dependent, usually the slot type of the corpus.
colorMap : dict, optional None

Which nodes of a tuple (or list of tuples) will be highlighted. If colorMap is None or missing, all nodes will be highlighted with the default highlight color, which is yellow.

But you can assign different colors to the members of the tuple: colorMap must be a dictionary that maps the positions in a tuple to a color.

  • If a position is not mapped, it will not be highlighted.
  • If it is mapped to the empty string, it gets the default highlight color.
  • Otherwise, it should be mapped to a string that is a valid CSS color.

color names

The link above points to a series of handy color names and their previews.

highlights takes precedence over colorMap

If both highlights and colorMap are given, colorMap is ignored.

If you need to micro-manage, highlights is your thing. Whenever possible, use colorMap.

condensed : boolean, optional False

interface option indicates one of two modes of displaying the result list:

  • True: instead of showing all results one by one, we show container nodes with all results in it highlighted. That way, we blur the distinction between the individual results, but it is easier to oversee where the results are. This is how SHEBANQ displays its query results. See also the parameter condenseType.
  • False: make a separate display for each result tuple. This gives the best account of the exact result set.

mixing up highlights

Condensing may mix-up the highlight coloring. If a node occurs in two results, at different positions in the tuple, the colorMap wants to assign it two colors! Yet one color will be chosen, and it is unpredictable which one.

condenseType : string, optional None
interface option The type of container to be used for condensing results. The default is app dependent, usually verse or tablet.
edgeFeatures : string | iterable, optional None

interface option Edge features that will be shown on the interface, in pretty displays. The selection of edge features to show will be in effect if forceEdges is True. Otherwise, the display of edge features depends on whether it is in the extraFeatures or tupleFeatures (which will be set after a query).

The default is app dependent, it consist of all the edge features in the dataset, except oslots.

edgeHighlights : dict

Custom highlighting of edges.

The keys are the names of edge features. For each such key, the value is a set or mapping of edges defined by that edge feature that should be highlighted. Only edges that are involved in the display will be highlighted.

If the value is a set, the specified edges will be highlighted with a default color (blue).

If it is a dictionary, it should map edges to colors. Any color that is a valid CSS color qualifies.

If you map an edge to the empty string, it will get the default highlight color.

An edge is a pair of nodes, represented as a tuple of two node numbers.

You can also map the following pseudo edges to colors:

  • (fromNode, None): all outgoing edges of fromNode;
  • (None, toNode): all incoming edges of toNode.

There are no edge highlights in plain display.

end : int, optional None
end is the end point in the iterable of results. If None, displaying will stop after the end of the iterable.
extraFeatures : string | iterable, optional ()

A string or iterable of (node-/edge-) feature names. These features will be loaded automatically. In pretty displays these features will show up as feature=value, provided the value is not None, or something like None.

Automatic loading

These features will load automatically, no explicit loading is necessary.

values from other nodes

Suppose you want to display a value from a related node, e.g. a gloss that is available on lex nodes but not on word nodes, and you want to show it on the word nodes. Then you may specifiy lex:gloss, meaning that Text-Fabric will look up a lex node from the current node (by means of L.u(w, otype='lex'), and if it finds one, it will read the gloss feature from it.

fmt : string, optional None

interface option fmt is the text format that will be used for the representation. E.g. text-orig-full.

Text formats

Use T.formats to inspect what text formats are available in your corpus.

full : boolean, optional False

For pretty displays: indicates that the whole object should be displayed, even if it is big.

Big objects

Big objects are objects of a type that is bigger than the default condense type.

hiddenTypes : string | iterable, optional None

interface option Node types that will not be shown in displays. All node types can be hidden, except the slot type and the section types. Structure types can be hidden.

Meaning

Nodes of hidden types will not be skipped, but they do not add visible structure to the display. The material under those nodes will still be displayed. For example, if the corpus has verses divided into half verses, and you are not interested in the half verse division, you can make half verses hidden. The content of the half verses is still shown, but the half verse division is gone.

The default is app dependent, usually the empty set.

showEdges : boolean | optional True
interface option If True, edges are shown in pretty displays, provided they are also selected in edgeFeatures. If False all edges are hidden.
hideTypes : boolean | optional True
interface option If True, hidden types are in fact hidden, otherwise the hiding of types has no effect.
highlights : dict | set, optional {}

When nodes such as verses and sentences and lines and cases are displayed by plain() or pretty(), their contents is also displayed. You can selectively highlight those parts.

highlights={} is a set or mapping of nodes that should be highlighted. Only nodes that are involved in the display will be highlighted.

If highlights is a set, its nodes will be highlighted with a default color (yellow).

If it is a dictionary, it should map nodes to colors. Any color that is a valid CSS color qualifies.

If you map a node to the empty string, it will get the default highlight color.

Highlights in plain display will be done, also for nodes deeply buried in the top node. Slots are higlighted by coloring the background, all other nodes by colored frames around their material.

one big highlights dictionary

It is OK to first compose a big highlights dictionary for many tuples of nodes, and then run prettyTuple() for many different tuples with the same highlights. It does not harm performance if highlights maps lots of nodes outside the tuple as well.

lineNumbers : boolean, optional False

interface option indicates whether line numbers should be displayed.

source data

Line numbers are with respect to the source data file that is contains the origin material of the node in question, if a datasource provides a feature that contains line numbers.

configuration

Whether a corpus has line numbers, and in which feature they are stored for which node types is configured in a corpus dependent app.

If the corpus has no line numbers, the default is None.

multiFeatures : boolean, optional False
interface option indicates whether pretty displays should show all possible node features provided they have a non-empty value. The feature otype is excluded from this.
noneValues : set, optional None

A set of values for which no display should be generated. The default set is None and the strings NA, none, unknown.

None is useful

Keep None in the set. If not, all custom features will be displayed for all kinds of nodes. So you will see clause types on words, and part of speech on clause atoms, al with value None.

Suppress common values

You can use noneValues also to suppress the normal values of a feature, in order to attract attention to the more special values, e.g.

noneValues={None, 'NA', 'unknown', 'm', 'sg', 'p3'}

None values affect all features

Beware of putting to much in noneValues. The contents of noneValues affect the display of all features, not only the custom features.

plainGaps : boolean, optional True
interface option indicates whether gaps types should be displayed in plain displays. In pretty displays gaps are marked by dotted left-right borders of the nodes around the gaps. In plain displays such borders are generally disruptive, but it is possible to show them.
prettyTypes : boolean, optional False
interface option indicates whether node types should always be displayed in pretty displays. The node type of slot nodes is never displayed.
queryFeatures : boolean, optional True
interface option indicates whether pretty displays should show the features mentioned in the last query and their values.
showGraphics : boolean, optional True

interface option indicates whether plain and pretty displays should include associated graphic elements.

configuration

Whether a corpus has graphics for some nodetypes and how to get them is configured in a corpus dependent app.

If the corpus has no graphics, the default is None.

showMath : boolean, optional False

interface option indicates whether plain and pretty displays should interpret the $ to mark mathematical formulas in TeX notation.

real dollars

If you have a corpus where the character $ is used in an ordinary way, this option should be set to False.

skipCols : set, optional set()

indicates columns to skip in show(), table(); no effect on prettyTuple() and plainTuple(). Also no effect if condensed is True.

The columns are not really removed, but the cells in the columns become empty.

So it will not disturb the highlighting of the tuples involved, and it does not disturb the working of colorMap.

The value may be a space-separated string of numbers, or an iterable of integers. Columns start at 1.

standardFeatures : boolean, optional True
interface option indicates whether pretty displays should show standard features and their values. If a feature is both a standard feature and it is mentioned in the last query, it will still be shown if standardFeatures is off and queryFeatures is on.
start : integer, optional None
start is the starting point for displaying the iterable of results. (1 is the first one). If None, displaying starts at the first element of the iterable.
suppress : set, optional set()
a set of names of features that should NOT be displayed. By default, quite a number of features is displayed for a node. If you find they clutter the display, you can turn them off selectively.
tupleFeatures : iterable of 2-tuples, optional ()

A bit like "extraFeatures" above, but more intricate. Only meant to steer the A.export() function below into outputting the features you choose.

It should be a tuple of pairs

(i, features)

which means that to member i of a result tuple we assign extra features.

features may be given as an iterable or a space separated string of feature names.

withPassage : boolean or set, optional True
indicates whether a passage label should be put next to a displayed node or tuple of nodes. When passed with table(), or plainTuple(), the value may also be a set of integers, indicating the columns whose nodes will be linked with a web link (the first column is column 1).
withLabels : boolean, optional True
interface option indicates whether pretty displays should show labels.
withNodes : boolean, optional False

interface option indicates whether node numbers should be displayed.

zooming in

If you are in a Jupyter notebook, you can inspect in a powerful way by setting withNodes=True. Then every part of a pretty display shows its node number, and you can use the following APIs to look up all information about each node that the corpus has to offer:

withTypes : boolean, optional False
interface option indicates whether node types should be displayed. The node type of slot nodes is never displayed.

    **interface option**
    indicates one of two modes of displaying the result list:

    *   `True`: instead of showing all results one by one,

    **interface option**
    The type of container to be used for condensing results.
    The default is app dependent, usually `verse` or `tablet`.

edgeFeatures: string | iterable, optional None
    **interface option**
    Edge features that will be shown on the interface, in pretty displays.
    The selection of edge features to show will be in effect
    if `forceEdges` is `True`.
    Otherwise, the display of edge features depends on whether it is in the

    If it is a dictionary, it should map edges to colors.
    Any color that is a valid
    [CSS color](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value)
    qualifies.

    If you map an edge to the empty string, it will get the default highlight color.

    An edge is a pair of nodes, represented as a tuple of two node numbers.

    You can also map the following pseudo edges to colors:

    *   `(fromNode, None)`: all outgoing edges of `fromNode`;
    *   `(None, toNode)`: all incoming edges of `toNode`.

    There are no edge highlights in plain display.

end: int, optional None
    `end` is the end point in the iterable of results.
    If `None`, displaying will stop after the end of the iterable.

extraFeatures: string | iterable, optional ()

    !!! hint "Automatic loading"
        These features will load automatically, no explicit loading is
        necessary.

    !!! hint "values from other nodes"
        Suppose you want to display a value from a related node, e.g. a `gloss`
        that is available on `lex` nodes but not on `word` nodes, and you
        want to show it on the word nodes.
        Then you may specifiy `lex:gloss`, meaning that Text-Fabric will
        look up a `lex` node from the current node (by means of `L.u(w, otype='lex')`,
        and if it finds one, it will read the `gloss` feature from it.

fmt: string, optional None
    **interface option**
    `fmt` is the text format that will be used for the representation.
    E.g. `text-orig-full`.

    !!! hint "Text formats"
        Use `T.formats` to inspect what text formats are available in your corpus.

full: boolean, optional False
    For pretty displays: indicates that the whole object should be
    displayed, even if it is big.

    !!! hint "Big objects"
        Big objects are objects of a type that is bigger than the default condense type.

hiddenTypes: string | iterable, optional None
    **interface option**
    Node types that will not be shown in displays.
    All node types can be hidden, except the slot type and the section types.

        Nodes of hidden types will not be skipped, but they do not add visible
        structure to the display. The material under those nodes will still
        be displayed. For example, if the corpus has verses divided into half verses,
        and you are not interested in the half verse division, you can make
        half verses hidden. The content of the half verses is still shown,
        but the half verse division is gone.

    The default is app dependent, usually the empty set.
