dependency generation simplified. + - mkdir invocations factored out to rule. + - DELETE_ON_ERROR: used now. + + - Streams: + - A new protocol between the close-stream function and its + lower-level implementation allows delegate streams to + implement a reference counting discipline for closing. + - open-file now supports a "T" mode for O_TMPFILE (on Linux, + or anywhere else O_TMPFILE is supported). + + - Sequences: + - New functions nested-vec and nested-vec-of for easily + constructing (simulated) multi-dimensional arrays. + - New mref accessor for multi-dimensional access. + - also has a side job calling curried functions. + - New csort-group function: + - Like sort-group, but uses csort instead of sort for key caching. + - New hist-sort function: make histogram of sequence, and sort + by descending frequency. + - New length-list-< function for testing whether a list is + shorter than a given length without traversing it beyond + that length. + - New length-< function for testing any sequence's length + against a value without traversing/forcing the sequence + to calculate its length. + - ref now documented as accessor, not just function. + - del operator now allowed on places that index into sequences + implemented by structures: + - requires both lambda and lambda-set methods. + + - Strings: + - New str-esc function for generic character escaping. + - New shell escaping functions: sh-esc, sh-esc-all, sh-esc-dq + and sh-esc-sq. + + - Packages + - New feature: local symbol renaming + - Symbols can be imported under alternative names. + - New use-sym-as function and :use-syms-as defpackage clause. + - Better idea than nicknaming packages (package-local nicknames). + + - Functional library: + - New: left-inserting pipeline operators: lflow, lopip, loand. + - New: macros orf and lorf for condensing certain op syntax. + - New: tap macro, for expressing side effects in pipelines while passing + through the value. + + - Syntactic places: + - New: ensure macro evaluates an expression and stores its value + into a place, if that place's current value is nil. + + - Pattern matching: + - some match-case instances are now transformed into casequal. + + - FFI: + - Now provides a setjmp macro, longjmp function as well + as a jmp-buf utility function that allocates a jmp-buf. + - Now possible to interact with libraries that use longjmp + for error aborts like libpng and such. + + - POSIX: + - chdir function takes stream or file descriptor, which are + handled via fchdir. + - New glob* function to complement glob: + - glob* supports the ** (double star) operator for recursing, + via its own implementation, not relying on glob providing that. + - glob* has its own implementation of brace expansion. + - New rlink function which is like link, but resolves the target path + if it denotes a symlink. + + - Listener: + - *listener-sel-inclusive-p* is now default, since most terminals + have block cursors by default. + - New feature: auto compound expression mode lets you omit + the parentheses. + + - Math: + - The tofloat and toint functions are now generic via the + user-defined arithmetic struct mechanism. + + - JSON: + - Allow integer objects to be printed rather than insisting on + numbers being floating-point. + - Allow lists (including lazy lists) to print as [ ... ] + rather than insisting on vectors. + + - Windows Installer: + - Does not require admin privileges any more; will install for + just the current user if the user isn't admin. + + - Documentation: + - big change: new hashing scheme for navigation and doc lookup. + - section titles now hashed in a more robust way that is resistant + against most kinds of edits. + - stdlib/doc-syms.tl file is now gone: one less thing to maintain. + - Numerous fixes in manual. + + Bugs + + - Compiler: + - numbers now externalized sanely in .tlo files: + - compile-file makes sure base 10 is used for integers + - floating point numbers written with sufficient precision + + - Loading: + - load-args-process bugfix: :compile action must load. + + - Streams: + - close-stream caches only successful result from underlying + function. + - a few close functions underneath close-stream were returning + nil in the successful case. + + - OOP: + - Fix segfault looking up special method after the static slots + table of the type has been resized. + + - Pattern matching: + - Missing autoloads for match-error and sys:match-pat-error, + causing compiled files containing pattern matching not to load. + + - Awk macro: + - prn returns nil + + - Search trees: + - bug: tree-delete-specific-node not using key fun. + + - Lib: + - Two bugs in flatten* function. + - Bug in deletion of (ref ...) place: incorrect when object is list. + + - Crypt: + - less strict error token detection for wider platform support. + + - Time: + - time-utc and time-local methods must subtract gmtime, not add. + - time-parse-utc and time-parse-local, likewise. + + - Build: + - Misspelled PLATFORM_LDLIBS corrected. + - Fix for _TIME_BITS being tied to _FILE_OFFSET_BITS + - Address autoload circular dependency involving stdlib/error.tl + that can fail builds under some library build orders. + + - Vim: + - Fix lack of recognition for char escapes in quasilit. + + + TXR 291 2023-08-06 |
