elvish-modules

Elvish is a wonderful alternative shell, much simpler, more lightweight and a less-cruft™ experience compared to POSIX shells like bash or zsh. It supports the ability to organise your code using modules and with namespaces. Elvish has a package manager, epm which allows you to use a github repo to call up your modules as needed.

Installing: add this to your rc.elv file:

epm:install &silent-if-installed github.com/iandol/elvish-modules 
use github.com/iandol/elvish-modules/cmds # my utility module
use github.com/iandol/elvish-modules/ai # my ai module
use github.com/iandol/elvish-modules/python # for python venv support
use github.com/iandol/elvish-modules/mamba # for conda/mamba support

...then to use:

cmds:if-external brew { echo "Brew is installed" } { echo "Brew not installed" }
cmds:do-if-path .config { echo "Config dir exists" }
ai:ask "What is the Capital of Ghana?"
mamaba:activate myenv

• cmds.elv — utility functions to perform helpful shell actions like add/remove (append-to-path, prepend-to-path, remove-from-path) or filter (filter, filter-out, filter-re, filter-re-out) lists like the path list; checking if executables are present (if-external) and others.

• ai.elv — Use an OpenAI-compatible API to ask an LLM a question: ai:ask. You can define the system prompt: $ai:system_prompt, the API base address: $ai:api_base, the API key: ai:api_key (can be stored at ~/.config/elvish/.key). Different model names can be stored in the map $ai:models. For example: ai:ask "What is the Capital of ghana?" &model=hermes — you can use local LLM apps LM-Studio and GPT4All, but it should work with any compatible local/cloud API provider. You can even use different chat history stores: ai:ask "What is the Capital of ghana?" &store=geography then later read the chat history using ai:get-messages &store=geography.

• mamba.elv — support for activating and deactivationg virtual environments for conda / mamba / micromamba package managers (note: only tested with micromamba).

• python.elv — a slight modification of iwoloschin's python module to support official venv virtual environments.
