Parameters

Fixed values for the whole program.

Global variables

var API_VERSION

TF API version.

TF offers and API to TF apps. This is the version that the current TF offers to its apps.

Apps require a version. The provided version and the required version must match exactly in order to get a working system.

We do not aim for backward compatibility, since it is very easy to obtain a new version of an app.

When TF loads a TF app, it will check the api version that the app requires against this version.

App requirement higher than TF API version

The user is advised to upgrade TF, or, alternatively, select an older version of the app

App requirement lower than TF API version

The user is advised to obtain a newer version of the app, or alternatively, downgrade TF

var BRANCH_DEFAULT

Default branch in repositories, older value.

var BRANCH_DEFAULT_NEW

Default branch in repositories, modern value.

var DOI_TF

DOI of an archived copy of this repo at Zenodo.

var GH

Name of GitHub backend.

var GL

Name of GitLab backend.

var GZIP_LEVEL

Compression level when compressing TF files.

var NAME

The name of the game: this program.

var OINTERF

Name of the feature that stores the outgoing inter-volume edges of a volume.

var OINTERT

Name of the feature that stores the incoming inter-volume edges of a volume.

var OMAP

Name prefix of features with a node map from an older version to a newer version.

The full name of such a feature is omap@oldversion-newversion

var ORG

GitHub organization or GitLab group.

This is where the repo that contains TF resides.

var OSLOTS

Name of a central feature in a TF data set: oslots maps non-slot nodes to the sets of slots they occupy.

var OTEXT

Name of a central (but optional) feature in a TF data set: otext has configuration settings for sections, structure, and text formats.

var OTYPE

Name of a central feature in a TF data set: otype maps nodes to their types.

var OVOLUME

Name of the feature that maps nodes of a work dataset to nodes in individual volumes in that work.

var OWORK

Name of the feature that maps nodes in an individual volume of a work to nodes in that work.

var PACK_VERSION

Data serialization version.

Plain text feature files will be compressed to zipped, pickled data structures that load must faster.

These methods evolve, sometimes in incompatible ways. In those cases we bump this version number. That will cause TF not to use compressed files that have been compressed by older, incompatible methods. Instead, TF will produce freshly compressed data files.

The compressed data files are stored in a directory .tf/{PVN}/ next to the original tf files, where {PVN} is the package version number.

tf.clean

var PICKLE_PROTOCOL

Pickle protocol level when pickling TF files.

var RELATIVE

Default relative path with a repo to the directory with TF files.

var REPO

GitHub repo or GitLab project.

This is the name of the repo that contains TF.

var SEARCH_FAIL_FACTOR

Limits fetching of search results to this times maxNode (corpus dependent)

var TRY_LIMIT_FROM

Performance parameter in the tf.search.search module.

var TRY_LIMIT_TO

Performance parameter in the tf.search.search module.

var URL_GH

Base URL of GitHub.

var URL_GH_API

Base URL of GitHub API.

var URL_GH_UPLOAD

Base URL of GitHub upload end point.

var URL_GL

Base URL of GitLab.

var URL_GL_API

Base URL of GitLab API.

var URL_GL_UPLOAD

Base URL of GitLab upload end point.

var URL_NB

Base URL of NB-viewer.

var VERSION

Program version.

This value is under control of the update process, as run by build.py in the top-level directory of the repo.

var WARP

The names of the central features of TF datasets.

The features otype and oslots are crucial to every TF dataset. Without them, a dataset is not a TF dataset, although it could still be a TF data module.

var YARN_RATIO

Performance parameter in the tf.search.search module.

var ZIP_OPTIONS

Options for zip when packing TF files.

This is for packaging collections of plain TF files into zip files to be attached to releases on GitHub / GitLab.

Not for .tfx files

This is not the zipping as done when .tf files are pickled and compressed to .tfx files.
