====== December January work: Brief overview of the last 6 weeks ======

**2024-01-21**

It's been a while since I got to write one of my regular blog posts. Hence, forgive me for being brief.


===== TracList =====

  * [[https://hg.pushbx.org/ecm/tractest/rev/a4a993791a8c|Round parens are accepted as relocation markers]] throughout
  * Allow to [[https://hg.pushbx.org/ecm/tractest/rev/e1607d030c21|highlight opcode after brackets in a line]]
  * Allow [[https://hg.pushbx.org/ecm/tractest/rev/99cc2f72ddb4|highlighting when a line ends in a dash after machine code]]
  * [[https://hg.pushbx.org/ecm/tractest/rev/b16a0b859789|Allow a match after brackets/parens]], but not if the match would start with a relocated value
  * If hint flle is empty, [[https://hg.pushbx.org/ecm/tractest/rev/41c462ca2aa2|dump newly displayed hints unconditionally]]


===== webecm =====

[[https://hg.pushbx.org/ecm/webecm/rev/0536e4d0e039|Mention ELDs]] in the lDebug overview.


===== lmacros =====

Add a boolean parameter to ''_autodigits'' to insert an underscore separator (NASM style) [[https://hg.pushbx.org/ecm/lmacros/rev/a170770f2e96|to group the output with a group width of 3 digits]].


===== inicomp =====

Instead of a default that corresponds to the full compressed plus uncompressed size, when errors occur [[https://hg.pushbx.org/ecm/inicomp/rev/9725324008b6|the inicomp test program will now display a zero]] to help mak.sh to detect the error and abort its run.


===== ldosboot =====

  * Add [[https://hg.pushbx.org/ecm/ldosboot/file/6e436c848f79/drload.asm|drload]] (iniload replacement that's kernel-only, EDR-DOS / FreeDOS load only)
  * Add [[https://hg.pushbx.org/ecm/ldosboot/file/6e436c848f79/drkernpl.asm|drkernpl]] (for single-file EDR-DOS load)
  * iniload: Only run MS-DOS v6 / IBM-DOS entry [[https://hg.pushbx.org/ecm/ldosboot/rev/2ec1c30d39f2|if CS is exactly 70h]] (implies support for NTLDR, BOOTMGR, and DOS-C IPL load)
  * iniload: [[https://hg.pushbx.org/ecm/ldosboot/rev/82071e8903ee|Support EDR-DOS load if file is at least 32 KiB sized]], detected by checking that the stack does not overlap file data
  * iniload: [[https://hg.pushbx.org/ecm/ldosboot/rev/e72fab017c25|Automatically enable EDR-DOS load]] if entire file is large enough

  * Fix error messages on sector L/W
  * [[https://hg.pushbx.org/ecm/msdebug/rev/03689492eb76|Call disk reset]] before and after sector access
  * [[https://hg.pushbx.org/ecm/msdebug/rev/7ec1ce47d8b6|Bump release number]] to release 1


===== Enhanced DR-DOS =====

  * Add a note on [[https://hg.pushbx.org/ecm/edrdos/rev/a074b5feec9c|default BPB detecting a FAT16]] when it actually results in a FAT12 FS (benign bug)

  * Use WarpLink and x2b2 [[https://hg.pushbx.org/ecm/edrdos/rev/369a13e27eea|to build DRDOS module]] (picked from SvarDOS, also requires SvarDOS re-implementation of fixupp utility)
