## What it is
Revise.jl is a Julia package that automatically updates function definitions in a running Julia session, so code edits, package updates, and git branch switches take effect without restarting the REPL. It avoids the overhead of reloading packages and re-JIT-compiling code after each change.

## Use cases
- edit Julia source code and see changes without restarting the REPL
- switch git branches mid-session and keep working
- update packages without losing the running Julia session
- reduce JIT recompilation time during iterative development
- keep debugger source views in sync with edited files

## When to choose
- you do iterative Julia development from the REPL or an editor
- your Julia startup and package load times are slow and disruptive
- you want editor-agnostic hot reloading in Julia

## When to avoid
- you are not working in Julia
- you need hot reloading for a deployed production service rather than interactive development

## Facets
- artifact type: library
- maturity: active
- function: developer-tools
- domain: developer-tools
- platform: cli, cross-platform
- tags: hot-reloading, repl, julia, live-coding, jit
