Create Self-Extracting Executable (Windows-only)

Demonstrates how to create a Windows self-extracting EXE. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local zip = chilkat.Zip.new()
zip:set_event_handler({
    -- Called periodically while a method runs (every heartbeat_ms milliseconds).
    abort_check = function()
        return false   -- return true to abort the method in progress
    end,
    percent_done = function(percentDone)
        print("Percent Done: " .. percentDone)
        -- Explicitly abort at 25% or greater.
        -- Remove this to allow for the HTTP download to run to completion.
        if percentDone > 25 then
            return true   -- abort the method in progress
        end
        return false   -- return true to abort the method in progress
    end,
    progress_info = function(name, value)
        print(name .. ": " .. value)
    end,
})

-- Initialize the zip object.  Because we're creating
-- a self-extracting EXE in this example, the filename
-- passed to NewZip will never actually be created.
local success = zip:new_zip("notUsed.zip")
if not success then
    print(zip.last_error_text)
    return
end

-- Append a directory tree.  The AppendFiles does
-- not read the file contents or append them to the zip
-- object in memory.  It simply appends references
-- to the files so that when WriteExe (or WriteZipAndClose,
-- or WriteZip, etc.) is called, the files are compressed
-- and added to the archive.
local recurse = true
zip:append_files("c:/temp/a/*", recurse)

-- Write "sfx.exe"
success = zip:write_exe("c:/temp/sfx.exe")
if not success then
    print(zip.last_error_text)
    return
end
