			Also lua has no continue ?? haha so I had to wrap my loop body in a function. Not a bad refactor, could add as an answer to https://stackoverflow.com/questions/3524970/why-does-lua-have-no-continue-statement

Razzi: Created page with "I figure before I get to writing fennel and stuff I should understand the host platform: namely lua!

New page

I figure before I get to writing fennel and stuff I should understand the host platform: namely lua!

I have lua 5.4 installed

First thing: I wanted to install the lua socket library to make a lua irc server. However the default install tried to write to /usr/ which failed with a permission error. Better to write to ~/.local

<pre>
$ cat ~/.config/lua/luarocks-5.4.lua
rocks_trees = {
home .. "/.local/lib/lua";
}

lua_interpreter = "lua5.4"
</pre>

Also need to set it up in ~/.profile:

<pre>
export LUAROCKS_CONFIG="$HOME/.config/lua/luarocks-5.4.lua"
export LUA_PATH="$LUA_PATH;$HOME/.local/lib/lua/share/lua/5.4/?.lua"
export LUA_CPATH="$HOME/.local/lib/lua/lib/lua/5.4/?.so"
</pre>

Ok then I can get the library:

$ luarocks install luasocket

and require it:

<pre>
$ lua
Lua 5.4.7 Copyright (C) 1994-2024 Lua.org, PUC-Rio
> require('socket')
table: 0x7fb742c07480 /Users/razzi/.local/lib/lua/share/lua/5.4/socket.lua
</pre>

And this works, however I don't have history in the lua repl !!

Luckily https://github.com/hoelzro/lua-repl provides history !

Just needed to also install linenoise as well for it to have command line editing:

<pre>
$ luarocks install linenoise
Installing https://luarocks.org/linenoise-0.9-1.rockspec

linenoise 0.9-1 depends on lua >= 5.1 (5.4-1 provided by VM: success)
