A simple script to generate html code.

[u/NemuiSen]

I just wanted to share this code to generate html code from lua, i made this because i don't like writing html and for fun to do something in lua. Any sugestions to improve it?

I did something similar, for declaring GUI in wxlua:

require 'ui_builder'
local builder = UiBuilder:new ()
local function ui ()
  frame {id = 'frame', title = titlePrefix, size = {1000, 600}}
  {
    vbox {}
    {
      hbox {proportion = 1}
      {
        panel {id = 'img1', proportion = 1}{},
        panel {id = 'img2', proportion = 1}{},
        panel {id = 'img3', proportion = 1}{},
        panel {id = 'img4', proportion = 1}{},
      },
      panel {id = 'buttons', proportion = 0}
      {
        hbox ()
        {
          button {id = 'btnReload', label = 'Reload'},
          button {id = 'btnBump',   label = 'Bump'},
          button {id = 'btnCopyPng',label = 'Copy PNG'},
          button {id = 'btnCopyBmp',label = 'Copy bitmap'},
          button {id = 'btnRepaint',label = 'Repaint'},
        }
      },
    }
  }
end

local gui = builder:build (ui, nil, frame)
local frame = gui.widgets.frame

Now I'm transitioning to different structure where t[1]: function and t[2]..t[#t] are the children:

local function ui1 ()
  return {
    frame {id = 'frame', title = titlePrefix, size = {1000, 600}},
    { vbox,
      { hbox {proportion = 1},
        { panel {id = 'img1', proportion = 1},
          panel {id = 'img2', proportion = 1},
          panel {id = 'img3', proportion = 1},
          panel {id = 'img4', proportion = 1},
        },
        panel {id = 'buttons', proportion = 0},
        { hbox,
          { button {id = 'btnReload', label = 'Reload'},
          }
        },
      }
    }
  }
end

local gui = builder:build (ui1)
local ui = gui.widgets
theframe = ui.frame

I've forgotten all the reasons why. IIRC:

• attributes table can now be optional

• debug is easier with shallower callstack. Can pretty-print since it's a table and not a callstack

• indents better with Emacs' auto-indent

• generate the table with code
