Install a pandoc binary for Github release page

Source: R/pandoc-install.R
pandoc_install.Rd

Binary releases of Pandoc are available on its release page. By default, this function will install the latest available version. pandoc_install_nightly() is a wrapper for pandoc_install("nightly"). pandoc_update() is an alias for pandoc_install() default behavior.

Usage

pandoc_install(version = "latest", force = FALSE)

pandoc_update()

pandoc_install_nightly(n_last = 1L)

Arguments

version

This can be either:

  • "latest" for the latest release

  • A version number (e.g "2.11.4") for a specific version

  • "nightly" for the last pandoc development built daily

force

To set to TRUE to force a re-installation

n_last

Set to n as integer to install the n-th from last nightly build. Default is last available build (1L)

Value

Invisibly, the path where the binary is installed otherwise. NULL if already installed.

Details

Pandoc versions are installed in user data directories with one folder per version. See pandoc_locate().

Only one nightly version is available at a time as there should be no need to switch between them. The latest nightly will be installed over the current one if any. Installing nightly version is useful for example to test a bug against the very last available built version.

Examples

# Install the latest pandoc version
pandoc_install() # or pandoc_update()
pandoc_uninstall("latest")
}
if (FALSE) { # rlang::is_interactive() && !pandoc::pandoc_is_installed("2.11.4")
# Install a specific pandoc version
pandoc_install("2.11.4")
pandoc_uninstall("2.11.4")
}
if (FALSE) { # rlang::is_interactive() && !pandoc::pandoc_is_installed("nightly")
