prepend_ciids_to_source: Prepend lines with one or more class instance identifiers to one or more sources

Description

These functions add lines with class instance identifiers to the beginning of one or more sources that were read with one of the loading_sources functions.

Usage

prepend_ciids_to_source(
  input,
  ciids,
  output = NULL,
  allOnOneLine = FALSE,
  designationSymbol = "=",
  preventOverwriting = rock::opts$get("preventOverwriting"),
  rlWarn = rock::opts$get(rlWarn),
  encoding = rock::opts$get("encoding"),
  silent = rock::opts$get("silent")
)
prepend_ciids_to_sources(
  input,
  ciids,
  output = NULL,
  outputPrefix = "",
  outputSuffix = "_coded",
  recursive = TRUE,
  filenameRegex = ".*",
  preventOverwriting = rock::opts$get("preventOverwriting"),
  encoding = rock::opts$get("encoding"),
  silent = rock::opts$get("silent")
)

Value

Invisibly, the coded source object.

Arguments

input

The source, or list of sources, as produced by one of the loading_sources functions.

ciids

A named character vector, where each element's name is the class identifier (e.g. "codeId" or "participantId") and each element is the class instance identifier.

output

If specified, the coded source will be written here.

allOnOneLine

Whether to add all class instance identifiers to one line (TRUE) or add then on successive lines (FALSE).

designationSymbol

The symbol to use to designate an instance identifier for a class (can be "=" or ":" as per the ROCK standard).

preventOverwriting

Whether to prevent overwriting existing files.

rlWarn

Whether to let readLines() warn, e.g. if files do not end with a newline character.

encoding

The encoding to use.

silent

Whether to be chatty or quiet.

outputPrefix, outputSuffix

A prefix and/or suffix to prepend and/or append to the filenames to distinguish them from the input filenames.

recursive

Whether to also read files from all subdirectories of the input directory

filenameRegex

Only input files matching this patterns will be read.

Examples

### Get path to example source
examplePath <-
  system.file("extdata", package="rock");

### Get a path to one example file
exampleFile <-
  file.path(examplePath, "example-1.rock");

### Parse single example source
loadedExample <-
  rock::load_source(exampleFile);

### Add a coder identifier
loadedExample <-
  rock::prepend_ciids_to_source(
    loadedExample,
    c("codeId" = "iz0dn96")
  );

### Show lines 1-5
cat(loadedExample[1:5]);
