readChangeLog: Read/write ChangeLog files

In saurfang/roxyPackage: Utilities to automate package builds

Description

These functions ans methods can be used to manage ChangeLog files.

Usage

readChangeLog(file, head = "ChangeLog for package",
  change = "changes in version", item = "  -")

writeChangeLog(log, file = NULL, head = "ChangeLog for package",
  change = "changes in version", item = "  -", lineEnd = 78)

initChangeLog(entry = list(changed = c("initial release"), fixed =
  c("missing ChangeLog")), package = "unknown", version = "0.01-1",
  date = Sys.Date())

Arguments

file	Character string, path to the ChangeLog file to read.
head	Character string, the headline text of the ChangeLog file (without the package name).
change	Character string, the text introducing each ChnageLog entry for a package version.
item	Character string, the text marking each entry item.
log	An object of class ChangeLog.
lineEnd	Integer number, indicates where to do line breaks.
entry	A (named) list of character vectors. The element names will become the ChangeLog sections, each vector element an item.
version	Character string, version number to look up.
date	The date of the ChangeLog entry in YYYY-MM-DD format. will be coerced into character. To keep the date stamp of a present entry, set date=NULL.
package	Character string, the package name.

Details

The ChangeLog files used for R packages are usually required to have a standard format, if they are supposed to be parsed by functions like tools::news2Rd:

1. entries are named "Changes in version <version number>" (and optionally a YYYY-MM-DD date string afterwards)

2. they have single changes properly itemized, by indentation and then either "o", "-" or "*" followed by space

3. optionally have categories as subsections, like "Fixed", "Changed" or "Added"

readChangeLog tries to read a given ChangeLog file and parse its content to generate a special ChangeLog object.

writeChangeLog takes such a ChangeLog object to write it back to a file. If file=NULL, the log will be returned to stdout.

initChangeLog generates a ChangeLog object from scratch, e.g., to get started with a new package.

Value

An object of class ChangeLog.
