Merge pull request #533 from Interlisp/nhb-rewrite-version-parser-v2

Extensive rewrite of various parts of the file name/version handling code. Converts a lot of unsafe string handling functions to safer variants. Passes buffer sizes in various places to enable overflow checks. Removes some unused variable declarations. Updates comments. Improves performance with alarm timeout setting when sequences of alarm set/cancel operations are performed. Adds GETFILEINFO processing for INODE_LO and INODE_HI attributes.
Removes assigned-but-not-used rval in DSK_getfilename and redundant test of current_len in conc_dir_and_name

 * The build will (attempt to) detect the OS-type and cpu-type. It will build binaries `lde` and `ldex` in `../`_`ostype.cputype`_ (with .o files in `../`_`ostype.cputype-x`_. For example, Linux on a 64-bit x86 will use `linux.x86_64`, while macOS 11 on a (new M1) Mac will use `darwin.aarch64`.
 * If you prefer `gcc` over `clang`, you will need to edit the makefile fragment for your configuration (`makefile-ostype.cputype-x`) and comment out the line (with a #) that defines `CC` as `clang` and uncomment the line (delete the #) for the line that defines `CC` as `gcc`.
+* If you want to do your own loadups to construct sysout files (see [the Medley repository](https://github.com/Interlisp/medley) for details), you also need the `ldeinit` binary, which you can build using `./makeright init`.

 ### Building with CMake
 We provide a `CMakeLists.txt` which provides mostly matching build capabilities to the `make` setup.

Nick Briggs	364bc1f31c	Removes StrNCpyFromLispToC(), renames StrNCpyFromCToLisp to MemCpyToLispFromNative Removes StrNCpyFromLispToC and the single use of it in LispStringToCString in the BYTESWAP implementation case. Rename StrNCpyFromCToLisp, which does NOT follow "strncpy" semantics, to be MemCpyToLispFromNative, where the types in the name match the types of the arguments, and the semantics (and argument order) are those of the C library "memcpy".	2025-07-25 14:12:30 -07:00

Frank Halasz	de1fafba7e	Merge pull request #536 from Interlisp/fgh_fix-2164-WSL1-try2 To fix Issue#2164, create infrastructure to compile Maiko for Windows System for Linux v1 as a separate OS from Linux Created makefile-wsl1-* files as well as makefile-init-wsl1-* files. Modified bin/osversion to detect wsl1 as a special case of linux so that the wsl1 makefiles would be selected appropriately by makeright. Did not make CMAKE changes for WSL1. Changed Build Release workflow (via changes to Dockerfile-maiko) to build wsl1 versions of lde, ldex, ldesdl and ldeinit for x86_64 and aarch64. These are now included in the release tars.	2025-06-16 00:30:06 -07:00

Matt Heffron	4994982a90	Adds the non-keypad arrow keys to be detected. With additional Medley calls to KEYACTION (below), they should work in TTYIN (i.e., XCL and Interlisp EXECs). I didn't try TEDIT. They are unrecognized in SEDIT. (In any case, their use there probably is pretty restricted by the nature of SEDIT.) (KEYACTION 'KEYPAD8 '(("Meta,^" 56 NOLOCKSHIFT) . IGNORE)) (KEYACTION 'KEYPAD6 '(("Meta,>" 54 NOLOCKSHIFT) . IGNORE)) (KEYACTION 'KEYPAD4 '(("Meta,<" 52 NOLOCKSHIFT) . IGNORE)) (KEYACTION 'KEYPAD2 '(("Meta,^J" 50 NOLOCKSHIFT) .
