• Fixed Integer divide by zero exception while taking profiling (Pull #76)
• add "--check-namespaces" option for enforcing namespace-as-URI rules
• doc: add local.css for admonition colors
• doc: add more xslt equivalents
• doc: add some more examples
• fix bug with uninitialzed gn_cur
• add slaxIsValidNamespaceUri() to give errors for broken namespace URIs and then add slaxSetCheckNamespaces() to turn it on/off since we have lots of broken namespaces
• fix function ref
• doc: fix issue with not emitting namespace statements (ns) when there are no child nodes. This is complicated by our behavior of putting a blank line between the namespaces and the content, so we have to pass a leading_newline boolean to slaxWriteChildren
• for slax:join(), don't follow the "next" link for non-RTF objects
• update test cases

• Document the impact of mvar += on vars
• add grouping to json (for jsonlint)
• add support functions for yaml/json grouping
• fix bug w/ += not making RTFs
• fix yaml grouping (for yamllint)
• update test cases

• Handle json conversion in case of invalid xml
• fix error message
• incorporate pull#73, fixing structure names and keeping the order of children unchanged

When the --profile-mode option is used without the --profile option, profile output is written to the file profile.output. Update the documentation.

• detect "one && /two", where the slash is led by an operator and the space should not be trimmed
• fix bad git tagging in 3.1.1

• Add support for ternary expressions in attributes, like:

<data name=$even ? 10 : 12 name=$name ?: "default">;

• Fixes #69
• add missing slaxTernaryExpand() call to fix #69
• remove error message from #69

• add line-wrapping code for attributes
• generate an error if ternary operators are using for attributes (#69)
• make slaxWriteAttributes() to move the logic out of slaxWriteElementFull()
• new major release: libslax-3.0.0, in honor of "version 1.3". I didn't move to "1.0.0" because I always thought it would be confusing that "1.0.0" supported slax-1.1, but I realized that I can make the "3" in "slax-the-language 1.3" echo in the version of "libslax-the-software 3.0.0".

• Fixes and enchancements around wrapping and formatting
• fix how nsDef entries are made
• fix comment handling, both parsing and formatting
• translate "not(x)" into "!x", handling more complex expressions
• nits:
• Drop the "upload-docs" target from the ancient "oxtradoc" manual
• Fix a bug in slaxLexerLookAhead where end-of-buffer isn't handled correctly
• a bug in slaxWriteEmitExpression was over-indenting seemingly randomly
• detect namespaces and handle them correctly
• drop the 'variable' test, do avoid slax-ext:node() references
• fix handling of comments to make it more consistent content
• improve wrapping in slaxWriteEmitExpression for overly long lines, fixing a bug and changing the "when to give up" logic a bit
• move more statements (for, for-each, while, apply-templates) to use slaxWriteExpression so --width is respected
• pass a trailer to slaxWriteExpression so it can reserve space for trailing text
• sort commands; add "git diff commit "
• teach slaxAttribAddValue to make namespaces (nsDef)
• update test cases

Small fix to detect <inttypes.h>

Introducing "version 1.3":

• Improved slaxproc Argument Parsing
  slaxproc -Fpitest-empty-39.slax --width=70

• Parentheses are now optional

    for-each $authors/author[life-span/born] {
        if life-span/died {
            <dead>;
        } else if life-span/born < 1900 {
            <very-old>
        }

        for $i in life-span/born ... life-span/died {
            <lived-in> $i;
        }
    }

• "output-method json"
• New slaxproc Parameter Syntax with "--param name=value"
• Profiler Option to invoke the profiler from the command line
• Format Width with --width 80
• xutil:slax-to-xml() and xutil:xml-to-slax()
• xutil:common() and xutil:distinct()
• New Bit Shift Functions
• New slaxproc Options (--xml-to-yaml, --encoding, --indent-width)
• Version Information with "--version" and "--version-only"
• slax:ends-with()
• slax:get-host()
• slax:join()
• New slax:printf() Functionality
• Hex Numbers (var $x = 0x45 + 0xBEEF;)

And several other interesting features.

Complete details in:

https://libslax.readthedocs.io/en/latest/notes.html#new-features-in-slax-1-3

From the commit logs:

• --dump-tree will dump the hierarchy of the script

• Add slax:ends-with() function (#57)
• Implement slax:xml-to-slax() (#20)
• sdb: add "info nodes" which list script nodes/hierarchy
• sdb: add "wall" profile-mode
• sdb: add "wall" to profiler
• add --indent-width option
• add --json
• add --profile and --profile-mode options
• add --version-only
• add --version-only; clean up option processing a bit
• add SLAX_VERSION to "slaxproc --version" output (#58)
• sdb: add dump command
• add percentage to profiler output
• add profiler-only support
• add shift functions to the bit library
• add slax:get-host() function
• add slax:join()
• add support for --json and 'output-method json' to make json output
• add xutil:common() and xutil:difference()
• add yaml writer
• convert hex numbers to decimal before making string tokens
• detect "var $x = call name(...)" and write it correctly (v1.3) (#34)
• detect .ext extension for prefixes that don't require libraries (aren't "extension"s)
• make -v additive and turn off parsing status for single -v, while allowing it with -vv
• move to getopt_long style option processing; add encoding option
• new 1.3 version, supporting unquoted order statements (#63)
• teach bit:from-int() to accept strings (#54)

Repair the effects of time:

Add some functionality to "gt":

• "gt br ls" lists branches; "gt merge"
• add "clone" verb
• add "unpatch"
• add 'gt self-help' since I keep forgetting the syntax
• add a coat of "fancy" to unpatch

Build environment:

• Add HAVE_HUMANIZE_NUMBER:-no logic, since humanize_number(3) is not standard
• Add SH_OPTS for debugging
• Adjust to new version of autoreconf; no need for m4/sqlite3, but it needs a test for SQLITE3_REQUIRED_VERSION; nuke "print" from xml2-config, etc.; add --with-sqlite3[=DIR]
• Remove the line numbers that libxslt emits, which breaks our tests
• Set language to En
• Some XPATH_* enums became #defines, so we need to protect against compiler warnings with -Wswitch
• add "scribble" to randomize memory
• add +slaxIoUseReadline (--no-readline) to avoid readline/libedit, when used without a tty (e.g. under lldb)
• add -lutil, since that's where humanize_number might live
• add LIBADD settings for dependent libraries
• add __printflike def for linux
• add check for memrchr (which it turns out we don't need)
• add missing slaxhumanize.h to noinst list

Install issues:

Intern code fixes:

• replace "pure-parser" with modern "api.pure"
• slaxDebugInitFlags(), which accepts flags including the profiler ones
• Add inttypes.h to get PRId64
• GCC pragma-fu to avoid warning with libxslt XSLT_RVT_LOCAL
• Keep the line number accurate inside comments (PR1486566)
• Stop indenting at double colon (L_DCOLON)
• Turn off -Wunused-but-set-variable (for bison 3.8.2)
• Update humanize with latest BSD source
• Use slaxSetupFakeContext() to make a fake context now that xmlSetupParserForBuffer is deprecated (libxml2-2.15.2)
• add L_UNDERSCORE (concat) to acceptable marking points for wrapping lines in the formatter
• add T_UNTERMINATED_STRING for a proper error
• add UNUSED to yynerrs
• add comment explaining that the back-reference example fails under macos
• add slaxAddChild to wrap xmlAddChild in acceptable logic
• alloca proper length buffer (#49)
• alloca() proper length buffer (#49)
• allow unquoted strings for order/etc statements (#63)
• autoupdate changes
• avoid NULL argument
• avoid https://bugzilla.gnome.org/show_bug.cgi?id=629325
• avoid memcpy call when sep is NULL, even if slen is zero
• bison 3.7.6 drops YYTERROR (now YYSYMBOL_YYerror)
• bit:to-int needs a check for negative numbers
• case-order is not implemented in libxslt
• commonize and simplify some variants of slaxAttribAdd*()
• fix (#61) allow true, false, and null in JSON
• get more input of look ahead isn't looking far enough (#13)
• handle the "json" output-method; start comments with slaxWriteBlankline not slaxWriteNewline
• make the psvi of the initial state (slaxMvarInit) as global or local so about errors when freed ("xsltFreeStackElem: Unexpected RVT flag")
• move from xmlAddChild to slaxAddChild, to protect against an issue where xmlAddChild coalesces the incoming node with existing nodes and frees the argument without letting the caller know
• stop substituting "/dev/std{in,out}" for "-"; use file handles directly

plus lots of documentation additions and update test cases
