Downloading eLua

You have a few options for downloading eLua:

• download a binary eLua image for your platform of choice. Binary images are provided with each official release. This is generally the best option if you have a bord that's officially supported by eLua (see here for details) and you want to have eLua up and running on your board as quickly as possible.
• download the source code. You can either download the source code of an official release or get the "bleeding edge" version from the SVN repository. Download the source code instead of a binary image if you need to make adjustments to the source code to support your board, or if you want to customize the eLua image, or if you simply want to take a look at what happens behind the eLua# prompt :)

Binary images

Pre-built images of eLua can be downloaded for each official release. Only the latest official eLua release is covered in this paragraph; if you want to download a pre-built image from an older release (although this isn't generally advisable), check this page. Choose the corresponding image file from the table below, flash it into your board, connect a serial terminal (or Ethernet if you board supports) and enjoy eLua. Also note that eLua binaries, like the source code distribution, include some example programs in it's file system, so you can run and play them (yes! we have games too! :), following the instructions in our Using eLua page. The available example programs are described in our examples page.

If you need a customized binary image for an already supported platform (for example with an autorun program, with some code of yours in the File System, with your LAN IP settings) and the instructions for building eLua didn't work for you, feel free to write us explaining what you need. We may find some time to build one for you and eventually make it available here too.

To understand what's in a file name (for example elua_lualong_lm3s8962.bin) check our building eLua page.

NOTE: Lua number type reffers to the built Lua interpreter number type, float or integer, as explained in the building eLua page.

Source code

If all you want is to take a quick peek at eLua's source code, but you don't need to download it, it's probably enough to use the BerliOS WebSVN interface. You can browse through the complete source of eLua using this method.
If you need to download the source code of eLua you can either:

• download the source code archive of an official release
• checkout the latest (bleeding edge) source code from the SVN repository in read-only mode (anonymous) mode
• checkout the latest (bleeding edge) source code from the SVN repository in read-write mode (for developers)

Check the table below for the download link of the source code associated with the latest official release of eLua. If you want to get the source code of an older version, check out this page.

If you'd rather have the very last development ("bleeding edge") version, just check it out from our Subversion Repository:

$ svn checkout svn://svn.berlios.de/elua/trunk

Once checked out, the repository can be easily updated by the svn client command:

$ svn update

Follow the steps below if you need write access to the eLua repository:

• if you don't have an account on developer.berlios.de, create one.
• contact us specifying your BerliOS ID and we'll give you write access to the repository.

Then checkout the repository:

$ export SVN_SSH='ssh -l <yourberliosid>
$ svn checkout svn+ssh://svn.berlios.de/svnroot/repos/elua/trunk

Once checked out, the repository can be easily updated:

$ svn update
