read_all {xfun} | R Documentation

## Read all text files and concatenate their content

### Description

Read files one by one, and optionally add text before/after the content. Then combine all content into one character vector.

### Usage

    read_all(files, before = function(f) NULL, after = function(f) NULL)

### Arguments

`files` | A vector of file paths.
`before, after` | A function that takes one file path as the input and returns values to be added before or after the content of the file. Alternatively, they can be constant values to be added.

### Value

A character vector.

### Examples

    # two files in this package
    fs = system.file("scripts", c("call-fun.R", "child-pids.sh"), package = "xfun")
    xfun::read_all(fs)

    # add file paths before file content and an empty line after content
    xfun::read_all(fs, before = function(f) paste("#-----", f, "-----"), after = "")

    # add constants
    xfun::read_all(fs, before = "/*", after = c("*/", ""))
