# luarocks
**luarocks** is the command-line interface for LuaRocks, the Lua package manager.
# Usage
```
luarocks [--server=<server> | --only-server=<server>] [--tree=<tree>] [--only-sources=<url>] [--deps-mode=<mode>] [<VAR>=<VALUE>]... <command> [<argument>]
```
Variables from the "variables" table of the [configuration file](config_file_format.md) can be overriden with VAR=VALUE assignments.
{|
| --server=_server_ || Fetch rocks/rockspecs from this server (takes priority over config file)
|-
| --only-server=_server_ || Fetch rocks/rockspecs from this server only (overrides any entries in the config file)
|-
| --only-sources=_url_ || Restrict downloads of sources to URLs starting with the given URL. For example, --only-sources=http://luarocks.org will allow LuaRocks to download sources only if the URL given in the rockspec starts with http://luarocks.org .
|-
| --tree=_tree_ || Which tree to operate on.
|-
| --local || Use the tree in the user's home directory. To enable it, see `[luarocks path](luarocks_path.md)`
|-
| --deps-mode=_mode_ || Select dependencies mode:
How to handle the list of rocks servers given in the rocks_servers array in the [config file](config_file_format.md).
* **one** - Consider only the tree at the top of the list (possibly, the one given by the --tree flag, overriding all entries from rocks_trees), ignore all others
* **all** - Consider all trees: if a dependency is installed in any tree of the rocks_trees list, we have a positive match.
* **order** - Consider only trees starting from the "current" one in the order, where the "current" is either:
* the one at the bottom of the rocks_trees list,
* or one explicitly given with --tree
* or the "home" tree if --local was given or local_by_default=true is configured (usually at the top of the list)
|-
| --verbose || Display verbose output of commands executed.

# Overview of the difference between "make", "build", "install" and "pack"
{|
| luarocks install modulename || downloads a binary .rock file and installs it to the local tree (falls back to "luarocks build modulename" behavior if a binary rock is not found)
|-
| luarocks build modulename || downloads a .src.rock or a rockspec and builds+installs it to the local tree.
|-
| luarocks build modulename-1.0-1.linux-x86.rock || extracts the rockspec from the rock and builds it as if the rockspec was passed in the command-line (i.e., redownloading sources and recompiling C modules if any).
|-
| luarocks build modulename-1.0-1.rockspec || builds+installs the rock using the given rockspec downloading the sources
|-
| luarocks make modulename-1.0-1.rockspec || builds+installs the rock using the rockspec using the contents of your current directory (kind of like the way make uses a Makefile) instead of downloading sources
|-
| luarocks pack modulename || grabs the rock from your local tree and packs it into a binary .rock file
|-
| luarocks pack modulename-1.0-1.rockspec || downloads the sources from the url and packs it into a .src.rock file
