App settings

Developers can create corpus apps by specifying a config.yaml with settings. These settings will be read, checked, and transformed into configuration data that is read by the app, see showContext()

See for examples: * bhsa. * uruk.

Config specs

Here is a specification of all settings you can configure for an app.

Each section below corresponds to a main key in the config.yaml of an app.

Everything is optional, an empty config.yaml is valid. Text-Fabric tries hard to supply reasonable defaults on the basis of the corpus data it has loaded.

apiVersion

To let Text-Fabric check whether its version matches the version of the corpus app

Default:

Default:

boolean false

browseNavLevel

The section level up to which the TF-browser shows a hierarchical tree.

Values

1 or 2

Default:

one less than the number of section types

The values set here are the defaults as given by this app. Not all options are relevant for all corpora. Only relevant options should be included. By setting the default to None, the option will not be shown on the TF-browser interface.

These options are described in tf.advanced.options: all options marked as interface option.

graphicsRelative

If not null, it is the path inside the repo to the directory that holds the graphics files

Default:

string null

moduleSpecs

You can specify modules that should always be loaded with the core data, as many as you want:

moduleSpecs = (
  dict(
      backend="gitlab",
      org="researcher1",
      repo="work1",
      relative="tf",
      corpus="speicalism1",

      org="researcher2",
      repo="work2",
      relative="tf",
      corpus="speicalism2",
      docUrl=(
          "{urlNb}/researcher2/work2/blob/master/programs/specialism2.ipynb"
      ),
      doi="uu.vvvv/archive.wwwwwww",
  ),
)

If modules have the same org or repo as the main data, these do not have to be specified. If a module has a relative attribute equal to tf, it can be left out.

Default:

list []

org

The GitHub organisation or the GitLab group under which your TF data resides.

Default:

string annotation

relative

The path inside the repo to the directory that holds the version directories of the tf data.

Default:

The GitHub repo or the GitLab project under which your TF data resides

Default:

string default

version

The version directory with the actual tf files that will be used.

Default:

string null

branch

The branch on the backend where the corpus data is stored.

Nowadays, repositories typically work with main where they used to work with master.

Default:

string master

pages

The url pattern of the Pages publication service of the backend, in case it is unpredicatable from the backend itself.

If this value is None, the following defaults are used, depending on the choice of backend:

• for github.com the default is github.io, so pages are addressed by org.github.io/repo;
• for gitlab.com the default is gitlab.io, so pages are addressed by org.gitlab.io/repo;
• for on-premiss gitlab, e.g. git.diginfra.net the default is pages.diginfra.net, so pages are addressed by org.pages.diginfra.net/repo;

If these defaults do not work for a particular situation, you can change the pattern here. For example, in the last case above, if the on-premiss gitlab has a repository mondriaan/letters whose pages are served on mondriaan.diginfra.vu/letters, you have to specify pages="diginfra.vu" .

Default:

void None

webBase

If present, the base url for an online edition of the corpus.

Default:

string null

webFeature

If passed, contains the name of the feature that stores the part of the weblink for that node that comes after webBase. This overrides webUrl in that when webFeature is present, and a node has a value for it, than that value will be used in composing the web link, rather than filling the template webLink with values from the headings.

Default:

string null

webHint

If passed, will be used as hint text when the user hovers over a web link

Default:

string null

webLang

If passed, the language in which section headings must be generated in web links

Default:

string null

webLexId

If present, it is either:

• the name of a feature that contains the lexeme id for lexeme nodes.

or

• true and then the app should implement app.getLexId(n) that computes lexeme ids for lexeme nodes.

The lexeme id is the one used in the online edition of the corpus to point to lexemes.

Default:

string | boolean null

webOffset

If present, it is a dictionary that specifies offsets between page numbers as derived from section headings and page numbers as needed in the query string for te url of the online resource (see webUrl).

Suppose we need to offset sections of level 2 depending on the section of level 1 they are in. For example, in the missieven corpus we have section levels 1=volume, 2=page, 3=line. In each volume, the logical page 1 must be translated into a higher number, depending on the number of preface pages in that volume.

The value of this parameter is a dict of dicts.

The first level of keys specifies the section level of the sections that needs offsets. In our example case we specify offsets for pages (level 1), so the key is 2.

The second level of keys are the values of section headings of the containing sections, the volumes. In our example these are integers 1 - 13.

Finally, the value is the offset that will be applied for pages in that volume. Values are positive or negative integers or 0. Missing values translate to 0 or the empty string.

webUrl

If present, webLink(node) will use this as a template to generate a url to an online edition of the node.

This may happen in two ways:

• From a feature whose name is given in webFeature we take the value for node n. If that value exists, it will be appended to the value of webBase and that will be the link.

• If webFeature is not given, or if it is given, but the feature has no value for n, the web link will be computed from the section headings. The following place holders will be honoured:

  • {webBase}: the webBase above
  • <1> : value for section heading 1
  • <2> : value for section heading 2
  • <3> : value for section heading 3
  • {version}: version of the TF resource

Default:

string null

webUrlZeros

If present, it specifies for each section level whether its heading should be padded with zeros. This padding will be applied to the real values substituted for <1>, <2> and <3> in the webUrl setting. If there is no value or the value is 0 for a section level, there will be no padding. Otherwise is specifies the length to which values should be padded.

E.g. if a value is 123 and the amount of padding specified is 5, two 0s will be prepended. This holds also for values that are not integers: if the value is a35 and the padding is 5, again two 0s will be prepended.

Default:

dict null

webUrlLex

If present, webLink(node) will use this as a template to generate a url to an online edition of the lexeme node.

The following place holders will be honoured: * {webBase}: the webBase value above * <lid> : value for the id of the lexeme * {version} version of the TF resource

Default:

string null

zip

Only used by text-fabric-zip when collecting data into zip files as attachments to a GitHub/GitLab release.

If left to null, will be configured to use the main repo and the modules.

You can also use this scheme to include other data from the repository. Note that graphics data will be packaged automatically.

You can specify the main repo, modules, and related data:

• zip=["repo"]: Only the main module.

• zip=["repo", "mod1", "mod2"] : if org and relative for the modules are the same as for are the main repo)

Default:

list ["repo"] + [("org1", "mod1", "relative1"), ("org2", "mod2", "relative2")]

where all modules mentioned in the moduleSpecs will be filled in.

typeDisplay

Here are the type-specific display parameters. If some types do not need configuration, you may leave them out.

The keys are node types as they exist in the corpus for which this is an app. The value for each key is a dictionary with the following possible contents (you may leave out keys if you are content with its default value).

Default:

dict {}

base

If present and true: this type acts as the base type.

Default:

boolean true for the slot type, false for other types.

boundary

If true, will only mark the start and end boundaries of the node, without wrapping its descendants in a new box.

Default:

boolean false

children

Which type of child nodes to be included in the display. The value should be a node type or a set of node types:

children: aya

children: - sura - aya

Default:

set, set()

condense

If true: this type is the default condense type.

When displaying tuples of nodes, they will be divided over displays of nodes of this type.

The default is:

true for the lowest section type, if there are section types defined in otext.tf.

If there are no sections, we pick a medium-sized node type. If there are no such node types, we pick the slot type, but this is pathological.

Default:

boolean false

exclude

Conditions that will exclude nodes of this type from the display.

All nodes that satisfy at least one of these conditions will be left out.

The value is a dictionary of feature name - value pairs.

exclude:
    type: term

Default:

dict, {}

features

Pretty displays: which node features to display as name=value.

You can also specify lookup feature values for upper nodes, e.g. lex:gloss which will look for a lex node above the current node and retrieve its gloss value.

Default:

list of string ''

featuresBare: feat1 feat2

Pretty displays: which features to display by value only (the feature name is not mentioned).

Things like lex:gloss are allowed.

Default:

list of string ''

flow

Pretty: whether the container should arrange its subdisplays as a column or as a row.

Values: hor, ver

Default:

string

• ver if level is 3 (typically section types), except for the verselike types
• ver if level is 0 (typically slot types and lexeme types)
• hor if level is 1 or 2 (typically linguistic types at sentence level) and for the verselike types

graphics

If true, then there is additional graphics available for nodes of this type.

The app needs to define a function

getGraphics(isPretty, node, nodeType, isOuter) => HTML code for sourcing the graphics

See uruk.

Default

boolean null

hidden

Plain and pretty: whether nodes of this type must be hidden by default. See for example the bhsa, where the atom types are hidden by default.

The user of the app can selectively mark any node type (except the slot type) as hidden, by means of hiddenTypes in tf.advanced.options.

The user can also switch between showing and hiding hidden node types by passing the display option hideTypes=False or hideTypes=True.

Default

boolean false

isBig

If true, then this type counts as a big type in plain displays.

Default

boolean false

label, template

Node contribution for plain and pretty displays (template is for plain displays, label is for pretty displays).

You can have features filled in by mentioning them by name in the template, e.g. {name1} - {name2}.

If you specify true as the template or label, the node information will be the result of:

• section and structure types nodes: a heading
• other nodes: plain text of the node

Default:

string

• true for the slot type
• true for the section and structure types
• "" for all other types

level

Pretty: the visual style of the container box of this node, values 0, 1, 2, 3. The bigger the number, the heavier the borders of the boxes.

The default is:

• 3 for types known as section or structure types, including the verselike types
• 0 for the slot type and types known as lexeme types
• 1 or 2 for the remaining types: the bigger types are 2, the smaller types are 1

Default

integer 1

lexOcc

If present, indicates that this is a lexeme type, and it points to the type of things that are occurrences of lexemes. Lexemes are displayed with an indication of their first and last occurrence.

Default

string slotType

lineNumber

If present, it should be the name of a feature that holds source line numbers.

Default

string null

stretch

Pretty: whether the children should be stretched in the direction perpendicular to their stacking.

The default is:

• true if the children form a row (then each child is stretched vertically)
• false if the children form a column (then each child is NOT stretched horizontally).

Default

boolean true

style

Formatting key for plain and pretty displays.

The label or template may need a special style to format it with. You can specify:

normal

normal non-corpus text

source

source text of the corpus (before conversion)

trans

transcription of corpus text

phono

phonological/phonetic transcription of corpus text

orig

unicode corpus text

anything else

will be inserted as an extra css class.

Default

string null

transform

Sometimes you do not want to display straight feature values, but transformed ones. For each feature you can specfiy a transform function f: E.g.

transform:
    type: ctype

The feature type, when computed for a node of the type we are configuring here, will yield a value which is transformed by function ctype to a new value. In your app code you have to implement:

def transform_f(app, origValue):
    ...
    newValue = ...
    return newValue

Default

dict {}

verselike

Whether this type should be formatted as a verse

The default is: true for the lowest section type, if there are section types in otext.tf.

But more types can be declared as verselike, e.g. halfverse in the bhsa.

wrap

Pretty: whether the child displays may be wrapped.

Default:

boolean

• true if the children form a row, such rows may be wrapped
• false if the children form a column; such columns may not be wrapped (into several columns)

writing

Code for triggering special fonts, see tf.writing.

Default:

string ''

    that computes lexeme ids for lexeme nodes.

The lexeme id is the one used in the online edition of the corpus to point to lexemes.

Default:
:   string | boolean `null`

---

### `webOffset`

If present, it is a dictionary that specifies offsets between page numbers as derived
from section headings and page numbers as needed in the query string for te url
of the online resource (see `webUrl`).

Suppose we need to offset sections of level 2 depending on the section of level 1
they are in.
For example, in the
[missieven corpus](https://github.com/clariah/wp6-missieven/blob/master/app/config.yaml)
we have section levels 1=volume, 2=page, 3=line.
In each volume, the logical page 1 must be translated into a higher
number, depending on the number of preface pages in that volume.

The value of this parameter is a dict of dicts.

The first level of keys specifies the section level of the sections that needs offsets.
In our example case we specify offsets for pages (level 1), so the key is `2`.

The second level of keys are the values of section headings of the containing sections,
the volumes.
In our example these are integers 1 - 13.

Finally, the value is the offset that will be applied for pages in that volume.
Values are positive or negative integers or 0.
Missing values translate to 0 or the empty string.

!!! note "integer or string"
    Headings may be integers or strings.
    If a heading is an integer, the offset will be added to it, if it is a string,
    the offset will be concatenated to it.

### `webUrl`

If present, `webLink(node)` will use this as a template to generate a url
to an online edition of the node.

This may happen in two ways:

*   From a feature whose name is given in `webFeature` we take the value for node `n`.
    If that value exists, it will be appended to the value of `webBase` and that
    will be the link.
*   If `webFeature` is not given, or if it is given,
    but the feature has no value for `n`, the web link will be computed from the
    section headings.
    The following place holders will be honoured:

    *   `{webBase}`: the webBase above
    *   `<1>` : value for section heading 1
    *   `<2>` : value for section heading 2
    *   `<3>` : value for section heading 3
    *   `{version}`: version of the TF resource

Default:
:   string `null`

---

### `webUrlZeros`

If present, it specifies for each section level whether its heading
should be padded with zeros.
This padding will be applied to the real values substituted for `<1>`, `<2>` and `<3>`
in the `webUrl` setting.
If there is no value or the value is 0 for a section level, there will be
no padding.
Otherwise is specifies the length to which values should be padded.

E.g. if a value is `123` and the amount of padding specified is 5, two `0`s
will be prepended.
This holds also for values that are not integers:
if the value is `a35` and the padding is 5, again two `0`s will be prepended.

Default:
:   dict `null`

---

### `webUrlLex`

If present, `webLink(node)` will use this as a template to generate a url
to an online edition of the lexeme node.

The following place holders will be honoured:
*   `{webBase}`: the `webBase` value above
*   `<lid>` : value for the id of the lexeme
*   `{version}` version of the TF resource

Default:
:   string `null`

---

### `zip`

Only used by `text-fabric-zip` when collecting data into zip files
as attachments to a GitHub/GitLab release.

If left to `null`, will be configured to use the main repo and the modules.

You can also use this scheme to include other data from the repository.
Note that graphics data will be packaged automatically.

You can specify the main repo, modules, and related data:

*   `zip=["repo"]`: Only the main module.

*   `zip=["repo", "mod1", "mod2"]` : if org and relative for the modules
    are the same as for are the main repo)

Default:
:   list `["repo"] + [("org1", "mod1", "relative1"), ("org2", "mod2", "relative2")]`

    where all modules mentioned in the moduleSpecs will be filled in.

---

## `typeDisplay`

Here are the type-specific display parameters.
If some types do not need configuration, you may leave them out.

The keys are node types as they exist in the corpus for which this is an app.
The value for each key is a dictionary with the following possible contents
(you may leave out keys if you are content with its default value).

Default:
:   dict `{}`

---

### `base`

If present and `true`: this type acts as the base type.

Default:
:   boolean `true` for the slot type, `false` for other types.

---

### `boundary`

If true, will only mark the start and end boundaries of the node,
without wrapping its descendants in a new box.

!!! caution "gaps"
    If the node has gaps, they will not be marked.

Default:
:   boolean `false`

---

---

### `children`

Which type of child nodes to be included in the display.
The value should be a node type or a set of node types:

children: aya

children:
  - sura
  - aya

!!! hint "Reductive"
    Use this if you want to reduce the number of section levels in a display.
    For example, in the Q'uran there are various types of sections, not very well
    related, and we do not want to get trees of all those sections. Rather, each section
    should unravel straight into the lowest one: the aya.

Default:
:   set, `set()`

---

### `condense`

If `true`: this type is the default condense type.

When displaying tuples of nodes,
they will be divided over displays of nodes of this type.

The default is:

`true` for the lowest section type, if there are section types defined in `otext.tf`.

If there are no sections, we pick a medium-sized node type.
If there are no such node types, we pick the slot type, but this is pathological.

Default:
:   boolean `false`

---

### `exclude`

Conditions that will exclude nodes of this type from the display.

All nodes that satisfy at least one of these conditions will be left out.

!!! hint
    Use this if you want to exclude particular nodes of some type, e.g. in
    [dss](https://github.com/etcbc/dss/blob/master/app/config.yaml).
    where we want to prevent line terminator signs.

The value is a dictionary of feature name - value pairs.

```
exclude:
    type: term
```

Default:
:   dict, `{}`

### `features`

Pretty displays: which node features to display as `name=value`.

You can also specify lookup feature values for upper nodes, e.g. `lex:gloss`
which will look for a `lex` node above the current node and retrieve its `gloss` value.

Default:
:   list of string `''`

---

### `featuresBare: feat1 feat2`

Pretty displays: which features to display by value only
(the feature name is not mentioned).

Things like `lex:gloss` are allowed.

Default:
:   list of string `''`

---

### `flow`

Pretty: whether the container should arrange its subdisplays as a column or as a row.

Values: `hor`, `ver`

Default:
:   string

    *   `ver` if level is 3 (typically section types), except for the verselike types
    *   `ver` if level is 0 (typically slot types and lexeme types)
    *   `hor` if level is 1 or 2 (typically linguistic types at sentence level) and
        for the verselike types

---

### `graphics`

If `true`, then there is additional graphics available for nodes of this
type.

The app needs to define a function

```
getGraphics(isPretty, node, nodeType, isOuter) => HTML code for sourcing the graphics
```

See [uruk](https://github.com/Nino-cunei/uruk/blob/master/app/app.py).

Default
:   boolean `null`

---

### `hidden`

Plain and pretty: whether nodes of this type must be hidden by default.
See for example the bhsa, where the `atom` types are hidden by default.

The user of the app can selectively mark any node type (except the slot type)
as hidden, by means of `hiddenTypes` in `tf.advanced.options`.

The user can also switch between showing and hiding hidden node types by passing
the display option `hideTypes=False` or `hideTypes=True`.

Default
:   boolean `false`

---

### `isBig`

If `true`, then this type counts as a big type in plain displays.

Default
:   boolean `false`

---

### `label, template`

Node contribution for plain and pretty displays (template is for plain displays,
label is for pretty displays).

You can have features filled in by mentioning them by name in the template, e.g.
`{name1} - {name2}`.

If you specify `true` as the template or label, the node information will be
the result of:

*   section and structure types nodes: a heading
*   other nodes: plain text of the node

Default:
:   string

    *   `true` for the slot type
    *   `true` for the section and structure types
    *   `""` for all other types

---

### `level`

Pretty: the visual style of the container box of this node, values 0, 1, 2, 3.
The bigger the number, the heavier the borders of the boxes.

The default is:

*   3 for types known as section or structure types, including the verselike types
*   0 for the slot type and types known as lexeme types
*   1 or 2 for the remaining types: the bigger types are 2, the smaller types are 1

Default
:   integer `1`

---

### `lexOcc`

If present, indicates that this is a lexeme type,
and it points to the type of things that are occurrences of lexemes.
Lexemes are displayed with an indication of their first and last occurrence.

Default
:   string *slotType*

---

### `lineNumber`

If present, it should be the name of a feature that holds source line numbers.

Default
:   string `null`

---

### `stretch`

Pretty: whether the children should be stretched in the direction perpendicular
to their stacking.

The default is:

*   `true` if the children form a row (then each child is stretched vertically)
*   `false` if the children form a column
    (then each child is NOT stretched horizontally).

Default
:   boolean `true`

!!! hint
    For some types in
    [uruk](https://github.com/Nino-cunei/uruk/blob/master/app/config.yaml)
    it is needed to deviate from the default.

---

### `style`

Formatting key for plain and pretty displays.

The label or template may need a special style to format it with.
You can specify:

`normal`
:   normal non-corpus text

`source`
:   source text of the corpus (before conversion)

`trans`
:   transcription of corpus text

`phono`
:   phonological/phonetic transcription of corpus text

`orig`
:   unicode corpus text

*anything else*
:   will be inserted as an extra css class.

Default
:   string `null`

---

### `transform`

Sometimes you do not want to display straight feature values, but transformed ones.
For each feature you can specfiy a transform function `f`:
E.g.

```
transform:
    type: ctype
```

The feature `type`, when computed for a node of the type we are configuring here,
will yield a value which is transformed by function `ctype` to a new value.
In your app code you have to implement:

```
def transform_f(app, origValue):
    ...
    newValue = ...
    return newValue
```

Default
:   dict `{}`

---

### `verselike`

Whether this type should be formatted as a verse

The default is:
`true` for the lowest section type, if there are section types in `otext.tf`.

But more types can be declared as verselike, e.g. `halfverse` in the
[bhsa](https://github.com/etcbc/bhsa/blob/master/app/config.yaml).

---

### `wrap`

Pretty: whether the child displays may be wrapped.

Default:
:   boolean

    *   `true` if the children form a row, such rows may be wrapped
    *   `false` if the children form a column;
        such columns may not be wrapped (into several columns)

!!! hint
    For some types in
    [uruk](https://github.com/Nino-cunei/uruk/blob/master/app/config.yaml)
    it is needed to deviate from the default.

---

## `writing`

Code for triggering special fonts, see `tf.writing`.

Default:
:   string `''`

def showContext(app, *keys, withComputed=True, asHtml=False)

Shows the context of the app App.context in a pretty way.

The context is the result of computing sensible defaults for the corpus combined with configuration settings in the app's config.yaml.

Parameters

keys : iterable of string

For each key passed to this function, the information for that key will be displayed. If no keys are passed, all keys will be displayed.

withComputed : boolean, optional False

If True, presents also the computed list of application settings.

asHtml : boolean, optional False

If True, return the resulting HTML rather than displaying it.

Returns

displayed HTML

An expandable list of the key-value pair for the requested keys.
