2024-04-12

  • Group Rob Landley's code together; add his copyright

    Need a few functions from Landley's toybox when making standalone wak versions

  • Mod UTF-8 support to obviate most dynamic allocation

    Mostly need to count codepoints in UTF-8 strings, so no need to allocate / free space for converted wide chars etc. Also allow for expansion in toupper() / tolower()

  • Add -b option (use bytes, not characters)

    Authored by @oliverkwebb

  • Initial UTF-8 support

    Research and initial implementation by @oliverkwebb

  • Merge rx_escape_str() into escape_str(), remove new_zstring_cap()

    Cleanup to remove/combine code

    Authored by @oliverkwebb

2024-04-06

  • Move math builtin code into main interp loop

    Inlined the math builtins into the main interpreter loop (thanks Oliver Webb), updated toybox test file with bitwise ops tests

  • Add bitwise operations

    From Oliver Webb, add some bitwise functions from gawk.

2024-03-31

  • Handle array deletions better

    Hash insert to first vacant or first marked-deleted slot

  • Move setlocale(LC_NUMERIC, "") call

    Do not do setlocale() on every conversion; just once at startup

  • Fix WEXITSTATUS() usage

2024-03-27

  • Use random() / srandom() for toybox

  • Add toybox awk test file

    Included original from toybox mailing list 2015: http://lists.landley.net/pipermail/toybox-landley.net/2015-March/015201.html. Had a couple bad tests.

  • Make file_or_pipe be 1/0 not 'f'/'p'

  • Tweak run.c format; move mathfunc[] into math_builtin(); rename time_ms() -> millinow()

  • Replace rx_compile(rx, pat) with xregcomp(rx, pat, REG_EXTENDED)

  • Remove unneeded inits of TT.scs elements

    TT.scs points to a struct already inited to zero where it's allocated in awk().

  • Update Makefile: Use -f to ignore missing files on rm

  • Change exprn(n) to expr(n); expr() to expr(0)

2024-03-26

  • Remove debug code; replace envp with environ

2024-02-22

  • Allow nul bytes in data files (not in source code yet). Still cannot have nul in multiline record (RS="") data. Work in progress.

  • Remove declarations for dev-only debugging build

    Minor code cleanup of some code needed only for dev debugging build (not in repo).

  • Replace top of stack index with pointer

    Profiling showed push_val() taking a lot of time. These changes make it several percent faster on many tests. Now test for stack getting close to overflow only at function call. Still possible if a source construct uses an absurd number of stack slots. Possible to test for that in compile phase but not yet worth the effort (and code space).

2024-02-15

  • Fix memory leak in assign_global()

    awk -v n=x 'BEGIN{f(n)};function f(n){}' caused a mem leak; see comment in assign_global(). Also tweak push_val(), zlist_append_zvalue(); change an exit(42) to exit(2).

2024-02-03

  • Fix previous fix for comma flag in printf

    Fixed (again) the regex for printf format. "-" needs to go first or else be escaped (to not be a range indicator). Moved "'" to end of "flags" bracket expression.

  • Match toybox error_exit() (puts newline at end); fix up error messages

  • Allow "'" in printf format for comma thousands separators; make ENVIRON init not modify program environment

2024-02-02

  • Update README.md

2024-02-01

  • Mod Makefile to keep mono.c and toybox/awk.c after 'make clean'; add those sources to repo

  • Update scripts to make cleaner mono.c and toybox awk.c files with copyright etc.

  • For toybox awk, change -r opt to -c, fix up usage message

  • Minor code cleanup: Remove unref'd opt_print_source (common.h) and a few commented-out lines (compile.c)

  • Update run.c: Remove unneeded force_maybemap_to_scalar() calls

  • Update main.c: Drop bogus -p option; change -r opt to -c (compile only); avoid warning on ?: operator missing middle term

2024-01-29

  • bug fixes and cleanup: Fixed some problems with maybemap objects; allow newlines before 'while' in 'do{}while()'; some code cleanup

2024-01-27

  • Close files at end of run, except stdin stdout stderr

  • Cleanup, incl upcasing #define's

    toybox preferred style is uppercase #define names

  • Prelim handling of regex RS

    RS can be a regex in most awks, though not in current POSIX spec. This may not be the best way but seems to work OK.

  • Simplify print, printf parsing

2024-01-08

  • Minor code cleanup: Fixed a few comments; tweaked code in print_stmt() for compiling output modes.

  • Fix setup_lvalue() bug

    setup_lvalue() can get a scalar in an array context and was leaving stack in a bad state. Fix to issue fatal diagnostic. Also tweak to keep ip always pointing to allocated space.

  • Clean up messages, message functions and exit code

    Try to conform better to toybox conventions; merge some message code

2024-01-03

  • Change option arg handling

    Changed arrays of -f and -v options into linked lists (arg_list) as used in toybox

  • Update file handling

    Change zfile array to linked list to reduce global space and remove limit on open files. Also format tweaks and minor fix to Makefile

2023-12-20

  • Code format cleanup: Remove extra spaces, tweak comments, rename an enum.

  • Reformat lbp_table[], add a few comments, rename a couple of enums.

  • Updated top and bottom toybox_awk_parts

    Mod to move globals into GLOBALS, use toybuf for pbuf (number formatting buffer), remove 'p' option flag (unused in toybox awk).

  • Update make_mono.awk

    Fixed up to accommodate 0BSD license line.

2023-12-19

  • Clean up scan.c

    Move tokstr and prevtok into global TT; removed scan_div_ok() and scan_regex_ok(). Change MAX() to maxof() (for toybox).

  • Move pbuf[] (buffer for formatting number to string) into global TT struct. Set up in main(), uses toybuf in toybox.

  • Moved global variables into a struct named TT to conform with toybox design.

  • Merge: 25706ea 0bfd5db

  • Merge branch 'main' of https://github.com/raygard/wak

  • typedef removal

    Toybox owner does not like typedefs.

2023-12-15

  • Update LICENSE

    Word-wrapped now.

  • Create LICENSE (0BSD)

  • Create README.md - Initial commit.

  • Add makefile and associated files

    Initial commit. Makefile and files needed to make monolithic (one file) and toybox versions.

  • Skip missing ARGV elements in nextfilearg()

    Was failing delargv.awk test. ARGV elements can be deleted, but should then be skipped when going to next file.

  • Set scalar or map (array) type on special variables, to catch type errors in compile phase.

2023-12-10

  • Code style cleanup pass

2023-12-04

  • Fix memory leak and type bug in setup_lvalue() (run.c)

2023-12-02

  • Rewrite printf handling in run.c

  • Get compile error count as exit code

  • Setup locale in main.c (a la toybox)

2023-11-07

  • Clean up compile.c -- error messages, function names

2023-11-02

  • Style -- remove space after '!'

  • Improve random number gen default seeding

  • Style -- replace most NULLs

  • First modularized version
