2.6

Release 2.6

Breaking changes

• removed deprecated libraries (scheme srfi-Nnn), use (srfi Nnn) instead,
• i/o scheduler enabled by default for reads, so manual embed code needs to do (start-io-scheduler) before (fork-symbol-interner ...). nothing changed if you use make-entry instead of manually starting thread controller, or if you don't read any input.
• write function made r⁷rs-compliant, now you can read the write output and have same result.
  • note: this can be used for libraries code minification (the (write (read)) removes comments and extra spaces)
• (owl format) moved to (otus format), because rewritten. this is for internal usage, but you must be warned
  • render-xxx renamed to format-xxx for symbols, strings, numbers, etc.

Just a reminder: in 2.4 -> 2.5 the system was renamed to execvp, and new system was introduced.

Major changes

• new i/o scheduler backported from owl-lisp (thx to Aki Helin).
• new functions wait, wait-read, bell, call, and smarter wait-mail (part of new i/o scheduler)
• mail now returns #false if mail is not delivered
• printing regex is printing regex now (instead of #)
• tarvenv and tarfolders introduced (will be enabled by default in next ol version)
  • the ol binary can now be standalone and include all required libraries along with the "autorun" script (new olp target added, new standalone example added)
• Unicode support updated to v.16.0.0
• "no more zombies" (c)
• ol (but not olvm) can handle pipes now
• win32 stdin goes really asynchronous (do not block background threads once user started typing in the windows terminal, grrrrr, i hate ms devs)
• regex library updated (added /|/ symbol, \\, g// returns string for strings, etc.)
• = goes universal: can compare strings, vectors, etc.
• new #\comma, #\backslash, #\semicolon, #\formfeed, #\vtab, etc. constants
• #ff(...) notation added
• #u8(...) notation added
• new function write-simple

Minor changes

• box and unbox moved to language core
• 32-bit linux fix for large files
• new OLVM_OWNLOGGER config define
• wine HAS_ -> HAVE_ vars update
• win32 waitpid, execvp, http/server, makefile fixes
• socket syscall upgraded (now with protocol selection)
• (file xml), (file json) updated
• build process updated (no more xxd required, for example)
• stat syscall can be overriden like open or write
• new each function
• olvm internal: IHALT -> IEXIT
• fix for long port numbers
• write strings fixed (for "\")
• write and write-simple updated with proper #ff()
• new (file html) library
• runtime-error now can have only 1 parameter
• http/server: added mime types, unicode fix, etc.
• write speedup
• dlopen/dlsym moved to base library
• http library support websockets now (usage example)
• ... fixes, cleanups, notes, etc.
