# info.nix -- install texinfo, set INFOPATH, create `dir` file
|
|
|
|
# This is a helper for the GNU info documentation system. By default,
|
|
# the `info` command (and the Info subsystem within Emacs) gives easy
|
|
# access to the info files stored system-wide, but not info files in
|
|
# your ~/.nix-profile.
|
|
|
|
# We set $INFOPATH to include `/run/current-system/sw/share/info` and
|
|
# `~/.nix-profile/share/info` but it's not enough. Although info can
|
|
# then find files when you explicitly ask for them, it doesn't show
|
|
# them to you in the table of contents on startup. To do that requires
|
|
# a `dir` file. NixOS keeps the system-wide `dir` file up to date, but
|
|
# ignores home-installed packages.
|
|
|
|
# So this module contains an activation script that generates the
|
|
# `dir` for your home profile. Then when you start info (and both
|
|
# `dir` files are in your $INFOPATH), it will *merge* the contents of
|
|
# the two files, showing you a unified table of contents for all
|
|
# packages. This is really nice.
