Nvims
The lazyman installation and configuration automatically configures
convenience aliases and an nvims shell function for the installed
Lazyman Neovim configurations. See ~/.config/nvim-Lazyman/.lazymanrc.
The nvims shell function, when executed, presents a fuzzy searchable menu
of the lazyman installed Neovim configurations. The lazyman installed
Neovim configurations are maintained in the file
~/.config/nvim-Lazyman/.nvimdirs. Entries in this file are what nvims
uses for its fuzzy selection menu. When Neovim configurations are installed
or removed with lazyman this file is updated accordingly.
Note also that a convenience key binding has been created to launch
nvims with ctrl-n.
The nvims Neovim configuration switching shell function was created by
Elijah Manor. He created an excellent
Neovim Config Switcher video in which
he provides details on use and customization of the nvims shell function.
Lazyman has incorporated, extensively enhanced, and adapted the nvims shell
function for use with the Lazyman installed Neovim configurations. The nvims
shell function is automatically configured during lazyman installation.

# On macOS the default is the 'open' command
# Linux default is 'python3 -m webbrowser' then 'xdg-open' then 'gio open'

# For example, to use 'gio' rather than Python's webbrowser module on Linux:
# export URL_OPEN_COMMAND="gio open"

# To specify the browser, set the BROWSER environment variable. For example:
# export BROWSER="w3m"
