AlcesteSource {tm.plugin.alceste}

Alceste Source

Description

Construct a source for an input containing a set of texts saved in the Alceste format in a single text file.

Usage

  AlcesteSource(x, encoding = "auto")

Arguments

x

Either a character identifying the file or a connection.

encoding

A character string: if non-empty declares the encoding used when reading the file, so the character data can be re-encoded. See the ‘Encoding’ section of the help for file. The default, “auto”, uses stri_enc_detect to try to guess the encoding; this may fail, in which case the native encoding is used.

Details

Several texts are saved in a single Alceste-formatted file, separated by lines starting with “***” or digits, followed by starred variables (see links below). These variables are set as document meta-data that can be accessed via the meta function.

Currently, “theme” lines starting with “-*” are ignored.

Value

An object of class AlcesteSource which extends the class Source representing set of articles from Alceste.
