I would think 5.3 would point to the latest release through their website, but maybe not.

Until they fix it, can your script point to a working release, like
http://www.lua.org/ftp/lua-5.3.5.tar.gz

As the title says, I think this wouldn't be hard to implement and would make sure eg. that the latest bugfixes are installed.

Step 2: parse semver string and install latest compatible version

eg.: luaver install 5.3 will install the latest 5.3 series release

Got myself the error compinit:477 after a clean install. Using zsh with oh-my-zsh, here.

it falls back to linux, which is wrong.

$ uname | tr "[:upper:]" "[:lower:]"
darwin

which is != macosx

Add the step to source bashrc in the install script. This could be done by executing the script in the current shell (instead of forking a sub shell).

Hi,

As things stand, if the user downloads and runs anything, including ./luavm help, luavm tries to install all its default working directories (~/.luavm etc.).

I'm not sure I think that this is the best procedure. I think it would be better to install those only when a user runs a command that requires them.

Beyond that, the installation commands have a problem. This is what the user sees when running ./luavm help

$ ./luavm help
usage: mkdir [-pv] [-m mode] directory ...
Unable to execute following command:
mkdir

 echo "[ -s ~/.luaver/completions/luaver.bash ] && . ~/.luaver/completions/luaver.bash" >> ~/.zshrc
 source ~/.zshrc
~/.luaver/completions/luaver.bash:60: command not found: complete

is there something i can do about it ?

Luaver fails to run with in a directory with spaces in the path. I think the problem is that the argument for cd on line 840 is not escaped.

As suggested by Jared Sartin:

I'm on 10.10.5 using zsh 5.2

Any idea on what I'm doing wrong?

might be related to #12, #11

Both running install.sh and installing luaver with homebrew installs an old version of luaver. This basically makes the function __luaver_get_platform() outdated. In MacOSX systems this means that luaver thinks it's running on linux, and compilation obviously fails.

When I try luaver install 5.3.4 I get

Any idea of whats wrong?

Whenever I start a new terminal session it writes
/usr/bin/which: no luarocks in (/home/jonathan/.luaver/lua/5.1.5/bin:/home/jonathan/.nvm/versions/node/v6.4.0/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/home/jonathan/.local/bin:/home/jonathan/bin) at the top. My guess is that it can't find luarocks in path.

I successfully ran luaver install-luajit 2.1.0-beta2 and it built LuaJIT. However, it did not show up after building Lua 5.1:

hisham@pointer ~/junkcode/noise]luaver current
==>  Current versions:
==>  lua-5.1.5
==>  luarocks-2.4.1

I tried to run luaver use-luajit and got a weird (buggy?) result:

hisham@pointer ~/junkcode/noise]luaver use-luajit 
==>  Switching to LuaJIT-
==>  Successfully switched to LuaJIT-

Apparently, this did nothing, fortunately.

hisham@pointer ~/junkcode/noise]luaver current
==>  Current versions:
==>  lua-5.1.5
==>  luarocks-2.4.1

So I tried it with an argument...

It would be quite nice to be able to create named virtualenvironments with luaver, just like in python. Sometimes, one has multiple projects with multiple incompatible dependencies for the same lua version.

It would be nicer if the install.sh script ran cd back to the original directory where I was originally, instead of leaving the shell at ~/.luaver. Perhaps it could also print in the end something like

Installation successful!
You can now run 'luaver' to see available commands.

Currently, it is only appending to .bashrc

I have created a better fish support that is I converted the luaver script file to luaver fish script file.

I would like to contribute it to this project if possible.

I have Lua 5.3 installed both as an Ubuntu package and through luaver. However, pkg-config points to the system Lua even when I am using luaver:

$ luaver use 5.3.5
==>  Switching to lua-5.3.5
==>  Successfully switched to lua-5.3.5

$ pkg-config --cflags --libs lua5.3
-I/usr/include/lua5.3 -llua5.3

Would you be open to creating a .pc file and adding it to PKG_CONFIG_PATH on luaver use? That way autoconf or other pkg-config users would find my luaver lua rather than the system lua. Thanks for considering this request!

(tested on Lubuntu Eoan)

Would it be possible to have a "rockset" feature like rvm's gemsets?

The idea is to allow the definition of not only different Lua versions, but also per-project Lua environments. So, if I had a project "foo" and a project "bar", both using Lua 5.3 but different rock sets, I could switch between their environments with the commands

$ luaver use [email protected]
$ luaver use [email protected]

The main benefit is that you get a finer control over the versions of the rocks you use, specially when there are incompatibilities. I never ran into this kind of situation though, so this feature might just be overkill. It does give me peace of mind to know that my projects have only the strictly required rocks installed in their environment.

The following script will not work as expected:

. ~/.luaver/luaver
if luaver install-luarocks install 5.3.1; then
    echo ok
else
    echo Something wrong
fi

The result was:

$ sh test.sh
No lua version set

$

while printing Something wrong is the expected behavior.

This is caused by luaver#L34, which kills not only the luaver function but also the whole batch process.
This behavior makes difficult to use luaver on the CI.

Since there is no exception handling mechanism on shells (kill -INT $$ is appearently not working), I suggest each command has explicit error handling using && and if.

Hi !
Do you think that luaver could run under msys2 shell on win7?

Tried installing it with the curl line from README.md, and got this error:

==>  Detected SHELL_TYPE: zsh
set_up_path:7: = not found

After that, I'm in the ~/.luaver directory, but typing the luaver command does nothing.

I launched bash, reran the curl installation line, and things worked as expected.

Hello,

I'd like to use luaver to install versions of luajit more recent than 2.1.0-beta3 or forks of luajit, because 2.1.0-beta3 segfaults on lots of well-behaved lua programs like this one https://gist.github.com/sharpobject/1a119447c15a3daa3933531f320a269d

Would you be open to a PR that adds the option to install more recent versions of luajit from https://github.com/LuaJIT/LuaJIT or forks of luajit from https://github.com/openresty/luajit2 or https://github.com/moonjit/moonjit?

If so, do you have any thoughts on how that should work? With the exception of moonjit, I don't think we will get tagged releases from these repositories.

Problem 1
In install.sh (line 32), I set LUAVER_DIR to a different dir which was not the default ~/.luaver
The profiles which were set in ~/.bashrc used ~/.luaver
They should have used the folder I set in the variable LUAVER_DIR

TDLR:
Wrong profiles for custom folder

Problem 2
In the luaver file (line 14), __luaver_LUAVER_DIR should automatically be set to the new luaver dir I set in install.sh

TDLR:
The install.sh script should pass on LUAVER_DIR from install.sh to __luaver_LUAVER_DIR in luaver

Note:
Please explicitly comment above line 14 in the luaver file that ~ cannot be use, instead ${HOME} should be used e.g. Cannot be '~/dir/dir', should be ${HOME}/dir/dir

dash is the default implementation of /bin/sh in Debian and Ubuntu and is a POSIX-compliant shell.

Making luaver dash-compatible will elegantly solve every portability issue such as on zsh and on macOS.

I think this is easy for luaver because luaver does not heavily use bash-specific features.

uname of my macbook air is Darwin.
it should map to the platform macosx, but it's detected as linux.

Nice software. A tiny correction: I think when a module is successfully installed the message like

lua-5.3.2 successfully installed. Do you want to this version? [Y/n]: Y

are probably meant to read

lua-5.3.2 successfully installed. Do you want switch to this version? [Y/n]: Y
