All of this talk about switching Lua environments reminded me that I
recently released a new version of runlua. Version 20160409 added a new
command-line option, -s, to scan a directory tree for Lua modules.
runlua is a POSIX shell-compatible script that permits you to specify which
Lua implementation (e.g. the API and/or release version, PUC or LuaJIT) to
execute and how to run it (e.g. -t ensures safe threading and -s will update
LUA_PATH, LUA_PATH_5_2, etc). It supports both command-line switches and
shell variables. The most recent version can be downloaded from
https://github.com/wahern/luapath/blob/master/runlua
runlua can be invoked directly or indirectly through the shebang
interpreter:
#!/bin/sh
_=[[
# ... additional setup here ...
exec runlua "0ドル" "$@"
]]
(But not like #!/path/to/runlua except on Linux and OS X.)
It doesn't currently support LuaRocks, though patches would be welcome.
Usage as described by `runlua -h`:
Usage: runlua [-e:il:vEr:j:Jms:tdpVh] [PATH [...]]
-e STRING execute statement
-i enter interactive mode after executing PATH
-l STRING require package
-v print interpreter version information
-E ignore environment variables
-r RANGE run specific Lua version
-j RANGE run specific LuaJIT version
-J exclude LuaJIT from candidate interpreters
-m NUMBER limit recursion to NUMBER
-s PATH scan directory tree for Lua modules
-t preload POSIX threading library
-d enable debug logging (twice for even more logging)
-p print path of Lua interpreter
-V print runlua version information
-h print this usage message
Examples:
-r5.2.1 only run PUC Lua 5.2.1 interpreter
-r5.1 run any Lua 5.1 interpreter, including LuaJIT
-r5.2-5.3 run any Lua 5.2 or 5.3 interpreter
-r5.2- run any Lua 5.2 or later interpreter
-j2.1 only run LuaJIT 2.1 interpreter
Environment:
RUNLUA_E=BOOLEAN same as -E if TRUE
RUNLUA_R=RANGE same as -r (use !RANGE to override -r)
RUNLUA_J=RANGE same as -j (use !RANGE to override -j or -J)
RUNLUA_M=NUMBER same as -m
RUNLUA_T=BOOLEAN same as -t if TRUE
RUNLUA_D=NUMBER set debug level (e.g. same -dd if 2)
RUNLUA_P=BOOLEAN same as -p if TRUE
Examples:
RUNLUA_R=5.2 runlua run any Lua 5.2 interpreter
RUNLUA_R=5.3 runlua -r5.2 same as above (-r has higher precedence)
RUNLUA_R='!5.3' runlua -r5.2 run any Lua 5.3 interpreter (! overrides -r)
BNF:
<PATH> ::= <STRING>
<RANGE> ::= <VERSION> | [VERSION] "-" [VERSION]
<VERSION> ::= <NUMBER> ["." <NUMBER> ["." <NUMBER>]]
<BOOLEAN> ::= <TRUE> | <FALSE>
<TRUE> ::= "yes" | "true" | "1"
<FALSE> ::= "no" | "false" | "0" | ""
