JOE 4.1

on GitHub

New or improved syntax files for the following languages:

• Groovy, R, Clojure, Rust, Coffeescript, Java, Scala, Swift, D,
  AVR, Ruby, Perl

New translations

• Chinese (zh_TW)

UTF-16 support

• JOE can now edit UTF-16BE and UTF-16LE files. It does this
  by converting them to UTF-8 during load and back to UTF-16 during
  save.

• Within JOE, native byte order is called UTF-16 and reversed order
  is called UTF-16R.

• If you change the encoding (with ^T E) between UTF-8, UTF-16 and UTF-16R,
  JOE will convert the file to the desired encoding on save.

New regular expression engine

• Old one was a recursive matcher, new one is compiled Thompson NFA matcher

• JOE now supports full regular expressions (but as before special characters are
  escaped by default), so:

  • It now supports alternative: X|Y
  • It now supports grouping and submatch addressing with parenthesis: a\(inside\)b
  • You can specify an explicit number of matches: X\{3} for XXX
  • Or a range of matches: X\{3,5} for XXX, XXXX or XXXXX
  • \! is a JOE extension: it's like \., but matches whole balanced expressions

• JOE also supports the standard regular expression syntax where
  these characters are not escaped.

  • Use the 'x' search & replace option for this, or use the
    '-regex' global option to make it the default.

• Standard syntax regular expressions are now used in the ftyperc
  file (which is used to determine the syntax of the file by
  inspecting its contents)

• Submatches within regular expressions can now be any size (up to
  the size of the disk!). Before this, they were limited to 16K.

• Case conversion allowed in replacement string, as in sed:
  everything between \U and \E converted to uppercase.

Unicode improvements

• Character class database has been updated to the latest version
  (Unicode 8.0.0)

• Switched to new character class data structure for faster Unicode
  (uses radix search instead of binary search).

• Key sequences in the joerc file are now UTF-8 coded Unicode.

  • Also you can specify Unicode in hexadecimal like this: U+F123

  • Note that even if you are using an 8-bit locale, keys are
    translated to UTF-8 before keymap lookup. This means you
    must use the Unicode code for your character in the joerc
    file, not the 8-bit code for the character.

• Jump to matching delimiter (Ctrl-G) now supports Unicode for word
  delimiters (for example, within XML tags).

• Identifiers within JOE now allow Unicode. For example, variables
  at the math prompt and JOE macros can use any letter.

• JOE now displays Unicode combining characters properly

• Syntax files are now UTF-8 coded and support Unicode syntax.

• Character lists in syntax files and search strings (regular
  expressions) now provide access to the Unicode category database
  and provide some other useful character classes:

  • Use \x{f123} to specify a particular character.

  • Use \p{Lu} to specify a Unicode character class: any one of
    L, Lu, Ll, Lt, Lm, Lo
    M, Mn, Mc, Me
    N, Nd, Nl, No
    P, Pc, Pd, Ps, Pe, Pi, Pf, Po
    S, Sm, Sc, Sk, So
    Z, Zs, Zl, Zp
    C, Cc, Cf, Cs, Co, Cn
    See: ftp://ftp.unicode.org/Public/5.1.0/ucd/UCD.html#General_Category_Values

  • Use \p{Cherokee} to specify any character from a named Unicode block.

  • \d for a digit, \D for not a digit

  • \w for a word character, \W for not a word character

  • \s for a space character, \S for not a space character

  • \i for identifier start character, \I for not identifier start character

  • \c for identifier continuation character, \C for not identifier continuation character

Code clean up

• Switch to ptrdiff_t for memory offsets and off_t for file offsets
  (prior to this, int and long were used). Now you can edit files
  larger than 4 GB on 32-bit systems.

• Give up trying force all strings to "unsigned char *" so that the
  code is less weird.

• Clean up code so that we get a clean compile even with many more
  warnings enabled. Going forward this helps find real bugs by
  highlighting new warnings.

• Remove C usage which is illegal in C++ so that JOE can be compiled
  by C++ compilers as well as C compilers. This is useful because
  C++ compilers sometimes warn about issues that C compilers miss.

Bugs fixed

• Fix bug where \ was not parsed correctly within syntax file
  character lists unless it was at the end of the string.

• Fix bug where position cursor history operations would mix
  pointers between different buffers if user had switched buffers in
  a window.

• Fix bug where lockup would happen if you try querysave when the
  only buffer left is the startup log.

• Default locale

  • If no locale set, default to C / POSIX, not ISO-8859-1
  • If locale is C / POSIX, set language to en_US (for aspell).

• Improve performance where JOE would seem to lock up if you tried
  to reformat a very long single word due to O(n^3) algorithm.

• Prevent filt and blkdel from modifying read-only buffers. This
  could happen if you run them from modifyable buffer but with block
  set in a read-only buffer.

• Fixed issue when recording paste in a macro. If you tried to
  play the macro, the pasted text is not inserted and JOE is
  stuck waiting for the bracketed paste end string.

• Fixed issue where syntax could not be set on command line with
  -syntax.

Minor enhancements

• Tab completion now works for the command and its file arguments
  after '!' in file prompts. Tab completion now works for the
  filename after '>>' in file write prompts.

• Tab completion now handles directory and file names with spaces
  in them.

• Backspace now jumps back to parent menu in ^T submenus (and
  remembers the cursor position within the parent)

• Macros after :def are now allowed to cross lines in the joerc file

• Make ^K ^SPACE same as ^K SPACE

• Quoted insert of TAB always inserts a TAB character, even when
  smart indent is enabled.

• Add options to control sending of bracketed paste mode command
  to terminal emulator (brpaste) and detection of paste by timing
  (pastehack).

• Modified ftyperc file syntax to reduce redundancy

• Added file type (as defined in ftyperc) setting option. For
  example, with "joe -type c fred" JOE will assume fred is a C
  language file. Use ^T F to change the file type from within JOE.

• Highlighter enhancement: when % is used in place of a character
  list, it matches the save_c delimiting character as-is (vs. &
  which matches the opposite character). For example, if save_c has
  {, then % matches { while & matches }. This allows JOE to
  highlight q{hello { there } } in Perl.

jmacs fixes:

• ^X b / ^X ^B were reversed

• ^X 0 printed an exit message for no reason

• ^X 0 now can pop shell windows

• M-^ deleted indentation but did not join with previous line

• Ignore case for letter commands: ^X i and ^X I are the same

• Fix bug where regular expressions were not working in incremental
  search when wrap is enabled (which is the case in jmacs).

ESC g (grep/find) and ESC c (compile) improvements

• Tab completion now works for the command and its arguments

• Change to the current directory before running the command

• Show the current directory in the compile window

• Show the exit status in the compile window

• Provide more consistent window setup during compile

• Parse "Entering directory `/home/xxxxxx'" messages to determine
  the directory containing the file with an error message.
