Module `tf.advanced.display`

Display

Where the advanced API really shines is in displaying nodes. There are basically two ways of displaying a node:

plain: just the associated text of a node, or if that would be too much, an identifying label of that node (e.g. for books, chapters and lexemes).
pretty: a display of the internal structure of the textual object a node stands for. That structure is adorned with relevant feature values.

These display methods are available for nodes, tuples of nodes, and iterables of tuples of nodes (think: query results). The names of these methods are

plain(), plainTuple(), and table();
pretty(), prettyTuple() and show().

In plain and pretty displays, certain parts can be highlighted, which is good for displaying query results where the parts that correspond directly to the search template are highlighted.

Display parameters

There is a bunch of parameters that govern how the display functions arrive at their results. You can pass them as optional arguments to these functions, or you can set up them in advance, and reset them to their original state when you are done.

All calls to the display functions look for the values for these parameters in the following order:

optional parameters passed directly to the function,
values as set up by previous calls to displaySetup(),
corpus dependent default values configured by the advanced API.

See tf.advanced.options for a list of display parameters.

Rendering

Both pretty() and plain() are implemented as a call to the render() function.

    """Produce the display API.

    The display API provides methods to generate styled representations
    of pieces of corpus texts in their relevant structures.
    The main end-user functions are `plain(node)` and `pretty(node)`.

    `plain()` focuses on the plain text, `pretty()` focuses on structure
    and feature display.

    Related are `plainTuple()` and `prettyTuple()` that work for tuples
    instead of nodes.

    And further there are `show()` and `table()`, that work
    with iterables of tuples of nodes (e.g. query results).

These working values remain in effect until a new call to displaySetup() assigns new values, or a call to displayReset() resets the values to the defaults.

show current values

The defaults themselves come from the corpus settings, which are influenced by its config.yaml file, if it exists. See tf.advanced.settings. You can show the current values by means of displayShow().

Parameters

show : list: Options of which the current value will be shown.
options : dict: Explicit values for selected options that act as overrides of the defaults.

Parameters

options : keys: Options of which the current value will be shown. If no option is passes, all options will be shown.

Parameters

tuples : iterable of tuples of integer

The integers are the nodes, together they form a table. The table maybe uniform or not uniform, which matters to the output. See below.

toDir : string, optional None

The destination directory for the exported file. By default it is your Downloads folder.

If the directory does not exist, it will be created.

toFile : boolean, optional results.tsv

The name of the exported file.

options : dict

Display options, see tf.advanced.options.

details

condensed Has no effect. Exports to Excel will not be condensed, because the number of columns is variable per row in that case. Excel itself has nice possibilities for grouping rows. You can also filter your tuples by means of hand-coding before exporting them.
condenseType The condense type influences for which nodes the full text will be exported. Only nodes that are "smaller" than the condense type will have their full text exported.
fmt This display parameter specifies the text format for any nodes that trigger a text value to be exported.
tupleFeatures This is a display parameter that steers which features are exported with each member of the tuples in the list.

If the iterable of tuples are the results of a query you have just run, then an appropriate call to displaySetup(tupleFeatures=...) has already been issued, so you can just say:
```
results = A.search(query)
A.export(results)
```

Results

A file toFile in directory toDir with the following content:

There will be a row for each tuple.

If the input tuples are uniform, i.e. each tuple has the same number of nodes, and nodes in the same column have the same node types, then the result table has the following layout:

The columns are:

R the sequence number of the result tuple in the result list
S1 S2 S3 the section as book, chapter, verse, in separate columns; the section is the section of the first non book / chapter node in the tuple
NODEi TYPEi the node and its type, for each node i in the result tuple
TEXTi the full text of node i, if the node type admits a concise text representation; the criterion is whether the node type has a type not bigger than the default condense type, which is app specific. If you pass an explicit condenseType=xxx as display parameter, then this is the reference condenseType on which the decision is based.
XFi the value of extra feature XF for node i, where these features have been declared by a previous displaySetup(tupleFeatures=...)

If the input tuples are not uniform, the layout is more primitive. There will be no header column, because the number of columns may vary per row. A row contains the successive information of all nodes in a tuple. Depending of the type of each node you get a number of columns of section information. Then follow two columns with the node and the node type. Depending on the type of the node, there follows a column with the text of the node. No additional features are produced.

Encoding

The exported file is written in the utf_16_le encoding. This ensures that Excel can open it without hassle, even if there are non-latin characters inside.

When you want to read the exported file programmatically, open it with encoding=utf_16.

Quotes

If the text of a field starts with a single or double quote, we insert a backslash in front of it, otherwise programs like Excel and Numbers will treat it in a special way.

Display the plain text of a tuple of nodes.

Displays the material that corresponds to a tuple of nodes as a row of cells, each displaying a member of the tuple by means of plain().

Parameters

tup : iterable of integer

The members of the tuple can be arbitrary nodes.

seq : integer, optional None

an arbitrary number which will be displayed in the first cell. This prepares the way for displaying query results, which come as a sequence of tuples of nodes. If None, no such number is displayed in the heading.

item : string, optional result

A name for the tuple: it could be a result, or a chapter, or a line.

position : integer, optional None

Which position counts as the focus position. If seq equals position, the tuple is in focus. The effect is to add the CSS class focus to the output HTML for the row of this tuple.

opened : boolean, optional False

Whether this tuple should be expandable to a pretty() display. The normal output of this row will be wrapped in a

<details><summary>plain</summary>pretty</details>

pattern, so that the user can click a triangle to switch between plain and pretty display.

Caution

This option has only effect when used in the TF browser.

options : dict

Display options, see tf.advanced.options.

_asString : boolean, optional False

Whether to deliver the result as a HTML string or to display it directly inside a notebook. When the TF browser uses this function it needs the HTML string.

Result

string or None Depending on asString above.
