Dave's Tiny Editor (DTE) v2.0.9

A working Windows text editor in 981 bytes.

Compiles with: MASM and Crinkler.

DTE is an extension of tiny.asm HelloAssembly by Dave Plummer https://github.com/davepl. The idea is to make a working windowed text editor in the sub-1KB category. It uses Crinkler https://github.com/runestubbe/Crinkler compression at build time.

DTE is basically a wrapper around the RICHEDIT50W control from the WinAPI. Versions 1.0+ use the EDIT control with Crinkler cranked and were built-up from tiny.asm then worked down to 890 bytes with Win Defender quite unhappy. Versions 2.0+ have Crinkler backed-off a bit and use RICHEDIT to gain cheaper access to Courier font and much larger files. 2.0+ was then worked down from 995 to 981 bytes.

Important: Programs using Crinkler can be flagged as a false positive by antivirus, including Windows Defender. You may need to make an antivirus exception folder to build this (especially for 1.0+), or Windows may delete the EXE as soon as the build completes. Therefore, try this out AT YOUR OWN RISK - NO WARRANTIES / NO GUARANTEES. You can accomplish this with PowerShell, but I am not going to tell you how. Sorry. You're on your own when messing with antivirus.

• MASM version used: Microsoft (R) Macro Assembler Version 14.44.35224.0
  

        In masm32\include\winextra.inc change:

    STD_ALERT struct<br>
        alrt_timestamp dd ?<br>
        alrt_eventname WCHAR  [EVLEN + 1] dup(?)<br>
        alrt_servicename WCHAR [SNLEN + 1] dup(?)<br>
    STD_ALERT ends

        to:

    STD_ALERT struct<br>
        alrt_timestamp dd ?<br>
        alrt_eventname WCHAR  (EVLEN + 1) dup(?)<br>
        alrt_servicename WCHAR (SNLEN + 1) dup(?)<br>
    STD_ALERT ends<br>

        The brackets on lines 13,14 were changed to parens.

• Build.bat contains: /LIBPATH:"C:\Program Files (x86)\Windows Kits\10\Lib\10.0.20348.0\um\x86"
  You may need to change to fit your system: /LIBPATH:"....\Windows Kits\10\Lib\(your version)\um\x86"
• You need to have Crinkler installed in a directory that has been added to PATH.
  Example: C:\utils\Crinkler.exe
