This is simple enough to do with a key-value loop using the Lua pairs() function: Lua: implicit table creation with string keys-why the extra brackets? (2) The normal syntax for indexing a table is t[val]. For string keys only, Lua provides an alternate syntax, where t.foo is exactly equivalent to t["foo"]. I believe that recent versions of ngx_lua have the problem that if you pass a table to ngx.print() they segfault. I say believe, because the builds I run have a lot of code that I've been hacking recently, so there may be a bug in that, but I tried back to version 2.0 of ngx_lua and it went away. Example: vim.env.FOO = 'bar' print(vim.env.TERM) * lua-vim-options* From Lua you can work with editor |options| by reading and setting items in these Lua tables: vim.o * vim.o* Get or set editor options, like |:set|.
2. I have a script in Lua and I need to print the Lua is a programming language that is used for writing and acknowledging the programmers with the help of inbuilt functions like Lua print. Calling a Lua print function helps to provide a better view to the development and implementation as it helps in making overall coding interesting and easy to adopt. Most pure lua print table functions I've seen have a problem with deep recursion and tend to cause a stack overflow when going too deep. This print table function that I've written does not have this problem. It should also be capable of handling really large tables due to the way it handles concatenation.
2. I have a script in Lua and I need to print the variable res, but I do not know how to do this print. I get the result of the function in another function, where I wanted to do print. function parseCSVLine (line) local res = {} local pos = 1 local sep = ',' while true do local c = string.sub (line,pos,pos) if …
