I would like ZEUS to add a header at the top of each file:

! Last edited on DATE TIME by PROGRAMMER

where ! is the comment identifier.

Is there a way to do this?
Is this part of Source Control?

Is there a way to do this?

This Lua script will insert such a comment to the top of the current file:

Code: Select all

function key_macro()
  -- macro only works for documents
  local document = is_document()

  if document == 0 then
    message("This macro only works for document files!")
    beep()
    return
  end

  -- macro only works for read/write documents
  local locked = is_read_only()

  if locked == 1 then
    message("The current document is marked as read only!")
    beep()
    return
  end

  -- move to start of document
  MoveDocumentStart()

  -- get the user name found in Options, Editor Options menu, User Defines
  local string user_name     = macro_tag("$UN")
  local string user_initials = macro_tag("$UI")
  local string user_id       = macro_tag("$UID")

  -- get date/time using zeus macro tags (see onlin help for more details)
  local string c_date = macro_tag("$DT<d MMMM yyyy> ")
  local string c_time = macro_tag("$T<HH:mm tt> ")

  -- build up comment string
  local string comment = "! Last edited on " .. c_date .. " " .. c_time .." by " .. user_name .. " " .. user_id .. " " .. user_initials .. "\n"

  -- print comment
  write(comment)
end

key_macro() -- run the macro

I would like ZEUS to add a header at the top of each file:

You will have to change the macro to only work for a given file extension. This code can be used to get the extension of the current file.

Code: Select all

-- get the current file extensions
local extension = macro_tag("$Ext")

Is this part of Source Control?

Most version controls do have such a feature. For more details you will need to refer to the documentation of the version control you are using. If you are using CVS, a search of the Web will probably supply the answer.

Alternatively you could modify the macro to also do the actual check-in by adding this line of code:

Code: Select all

-- check in the file
SccFileCheckIn()

That works quite well.

I made a few modifications:
1) check to see if there is already a time stamp line
2) check the file extensions (as you suggested)
3) restore the cursor position after the time stamp is updated
4) set to insert mode so I don't overwrite the first line!
5) save the file
6) associate the file with Cntl-S

I may update my code if for Cntl-A (save all files) using
1) is_modified
2) navigateviewnext
and cycle through all the open files, saving code that has been modified with the updated time stamp

This is what I'm using now:

Code: Select all

function key_macro() 
  -- macro only works for documents 
  local document = is_document() 
  if document == 0 then 
    message("This macro only works for document files!") 
    beep() 
    return 
  end 

 -- don't set header or save unmodified documents
  local changed = is_modified()
  if changed == 0 then
    return
  end

  -- macro only works for read/write documents 
  local locked = is_read_only() 
  if locked == 1 then 
    message("The current document is marked as read only!") 
    beep() 
    return 
  end 

  -- get the current file extensions 
  cExt = macro_tag("$Ext")
  cExt = string.lower(cExt)
  if cExt == ".for" then
    screen_update_disable()

  -- do not want to overwrite the first line!
    InsertModeSet()
    iCur = get_cursor_pos()
    iLin = get_line_pos()
  -- move to start of document 
    MoveDocumentStart()
    cLine = get_line_text()
    if string.sub(cLine,1,16) == "! Last edited on" then
      LineCut()
    end

  -- get the user name found in Options, Editor Options menu, User Defines 
    local string user_name     = macro_tag("$UN") 
    local string user_initials = macro_tag("$UI") 
    local string user_id       = macro_tag("$UID") 

  -- get date/time using zeus macro tags (see onlin help for more details) 
    local string c_date = macro_tag("$DT<d MMMM yyyy> ") 
    local string c_time = macro_tag("$T<HH:mm tt> ") 

  -- build up comment string 
    local string comment = "! Last edited on " .. c_date .. " " .. c_time .." by " .. user_name .. " " .. user_id .. " " .. user_initials .. "\n" 

  -- print comment 
    write(comment)
    set_line_pos(iLin)
    set_cursor_pos(iCur)
    screen_update_enable()
    screen_update()
  end
  FileSave()
end 

key_macro() -- run the macro
