Rdo_set_section: Replace a section in an Rd file

In Rdpack: Update and Manipulate Rd Documentation Objects

Replace a section in an Rd file

Description

Replace a section in an Rd file.

Usage

Rdo_set_section(text, sec, file, ...)

Arguments

text	the new text of the section, a character vector.
sec	name of the section.
file	name of the file.
...	arguments to be passed on to Rdo_modify.

Details

Parses the file, replaces the specified section with the new content and writes the file back. The text is processed as appropriate for the particular section (sec).

For example:

Rdo_set_section("Georgi N. Boshnakov", "author", "./man/Rdo2Rdf.Rd")

(Some care is needed with the author field for "xxx-package.Rd" files, such as "Rdpack-package.Rd", where the ⁠Author(s)⁠ field has somewhat different layout.)

By default Rdo_set_section does not create the section if it does not exist, since this may not be desirable for some Rd files. The "..." arguments can be used to change this, they are passed on to Rdo_modify, see its documentation for details.

Value

This function is used mainly for the side effect of changing file. It returns the Rd formatted text as a character vector.

Author(s)

Georgi N. Boshnakov

Examples

fnA <- tempfile("dummyfun", fileext = "Rd")
dummyfun <- function(x) x
reprompt(dummyfun, filename = fnA)
Rdo_show(tools::parse_Rd(fnA))

## set the author section, create it if necessary.
Rdo_set_section("A.A. Author", "author", fnA, create = TRUE)
Rdo_show(tools::parse_Rd(fnA))

## replace the author section
Rdo_set_section("Georgi N. Boshnakov", "author", fnA)
Rdo_show(tools::parse_Rd(fnA))
