Re: More complete std.optparse example?

[gary@...]

Hi Dan,

Thanks for your interest in the project!

The content of arg and opts depends on what you wrote in help :-)

You can explore what happens by adding this code:

for k,v in pairs (opts) do print ("opts['" .. tostring(k) .. "']", v) end
for i,v in ipairs (arg) do print ("arg[" .. i .. "]", v) end

And then running your program with various options to see what happens.

You can also see a more complex example in specl, taking help from:

https://github.com/gvvaughan/specl/blob/master/lib/specl/version.lua

And parsing in process_args() from:

https://github.com/gvvaughan/specl/blob/master/lib/specl/main.lua

HTH,

I'm trying to use std.optparse for the first time. The example shows
me how to get a parse arg and opt, but I don't know how to test
individual options from there.

local parser = OptionParser (help)
local arg, opts = parser:parse (_G.arg)
...

What should ... be?

Thanks,
