Progress has been made!
- reading the file
- separating out the user names from the message
In preparation for further error messa–I mean, progress–each line now has a UID (date to the second and the position in the file it was read–if it isn’t unique Something Went Wrong™). Username has been stripped of surrounding <>'s and symbols. And look, there’s the rest of the message!
The code was very hacky and I’m sure it can be streamlined considerably. I also experimented with functions. They’re my little buddies from a past era.
Gotta love the little guys!

the check_log() function grew a bit, but most of it is debug messages.
local function check_log(self, handle) -- the master function for log reading.
local functn = "check_log "
if log_accessed == 0 then -- should only be donce once, when timer first activates.
-- file_length = check_file_size(filename) -- check what the file length is when first opened.

file_length = logfile:seek("end") -- length of file when first accssed
print(scriptn .. functn .. "file_length " .. file_length) -- debug
-- log_accessed = 0
log_accessed = log_accessed + 1 -- increment and hopfully not read the same line again
print(scriptn .. functn .. "log_accessed 1 " .. log_accessed) -- debug
else
-- length_alpha = check_file_size(filename) -- log_accessed lets me reuse the function
local logfile = io.input(filename, "r") -- access in read mode
length_alpha = logfile:seek("end") -- length of file when first accssed
-- print(scriptn .. functn .. "file_length 2 " .. file_length) -- debug
-- log_accessed = 0
log_accessed = log_accessed + 1 -- to prevent an update to file size too soon
-- print(scriptn .. functn .. "log_accessed 2 " .. log_accessed) -- debug
if length_alpha > file_length then -- if the file size is larger, there's new lines to read
-- tail_log(length_alpha) -- function to do the reading
-- -- testing the log print.
-- local logfile = io.input(filename, "r") -- done above, don't need?
logfile:seek("set", file_length) -- "set" the "pointer" to file_length
if logfile then -- double check it is not "nil"
for i=1,seek_lines do -- start iterating though a possible number of lines (some might have been added)
local log_lines = io.read("*l") -- I thnk this reads by "next line to "end of line". If doesn't do what I want, then there's the line() call to try.
file_length = logfile:seek() -- set file length to the new EOF?
if not log_lines then -- if log_lines is empty, stop
break -- stop reading
end
print(scriptn .. functn .. "log lines" .. log_lines) -- debug & print the log_lines
-- figure out the message UUID. Timestamp + file_length will be plenty specific.
raw_msg = log_lines
local msg_time = grab_time(raw_msg)
local msg_user = grab_user(raw_msg)
local msg_body = grab_body(raw_msg)
local msg_uid = msg_time .. "-" .. file_length -- not sure I want this to be a number so using a dash
--msg.post("go#test_http", "log_parsed", {line = log_lines}) -- send messge to the GUI node.
print(msg_uid .. "##".. msg_user .. "##" .. msg_body)
msg.post("go#test_http", "log_message", {uid = msg_uid, user = msg_user, body = msg_body}) -- send messge to the GUI node.
end
end
file_length = length_alpha -- after reading, increase the stored filesize.
-- print(scriptn .. functn .. "file_length 3 " .. file_length) -- debug
end
end
end
Meanwhile, back in the gui_script there is a little friend in the on_messages
function on_message(self, message_id, message, sender)
if message_id == hash("log_parsed") then -- check message ID
local log_window_node = gui.get_node("text_log_window") -- get the node info
gui.set_text(log_window_node, message.line) -- print message to text node
end
if message_id == hash("log_message") then -- check message ID
local log_window_node = gui.get_node("text_log_window") -- get node info
local glue_message = message.uid .. ": " .. message.user .. ": " .. message.body -- our new friend from readchatlog
-- {uid = msg_uid, user = msg_user, body = msg_body} -- my memory is terrible
gui.set_text(log_window_node, glue_message) -- print message to text node
end -- go, little buddy, go!
end
I think I figured out how to get more than one message to show up at a time: duct tape!
