v2.9.0

• Update to Unicode 17.0.

• Fix sorting of print and search with a custom -format flag (it sorted randomly if %(dec) wasn't included).

• Sometimes the header would be printed on the second line when U+00 was included in the output

• Recognise c:[cat-name] to print a category in addition to cat:[cat-name].

v2.8.0

Update to Unicode 16.0.

v2.7.0

• Improve -format flag:

  • Add %name as an alias for %(name l:auto); this is a lot less typing and requires less shell quoting, and >90% of the time this is what you want.

  • Automatically prepend character, codepoint, and name if the format flag starts with +; for example:

    % uni identify -f +'%unicode %plane' a
                 Name                 Unicode Plane
    'a'  U+0061  LATIN SMALL LETTER A 1.1     Basic Multilingual Plane
    

  This should make quickly printing some property a lot quicker.

• Align and colourize JSON output.

• Update CLDR information, adding significantly more aliases for emojis.

• Add cells column, which returns how many cells a codepoint will display at (0, 1, or 2).

• Add aliases column, which lists the alias names. Also add this to the default output:

  % uni s factorial
       CPoint  Dec    UTF8        HTML       Name  Aliases
  '!'  U+0021  33     21          !     EXCLAMATION MARK [factorial, bang]
  

• Add refs columns, which references other related/similar codepoints:

  % uni p -q U+46 -f '%(name): %(refs)'
  LATIN CAPITAL LETTER F: U+2109, U+2131, U+2132
  
  % uni p -q U+46 -f '%(refs)' | uni p
       CPoint  Dec    UTF8        HTML       Name  Aliases
  '℉'  U+2109  8457   e2 84 89    ℉   DEGREE FAHRENHEIT
  'ℱ'  U+2131  8497   e2 84 b1    ℱ     SCRIPT CAPITAL F [Fourier transform]
  'Ⅎ'  U+2132  8498   e2 84 b2    Ⅎ   TURNED CAPITAL F [Claudian digamma inversum]
  

• Allow arguments to printto start or end with a comma or slash. This comes up when copy/pasting some list of codepoints from another source; there's no real reason to error out on this.

• Allow listing unicode versions with uni list unicode and planes with uni list planes.

• uni list without arguments errors, instead of listing all.

• Add h format flag to not print the header for this column.

v2.6.0

• Update to Unicode 15.1.

• Add "script" property – also supported in the list and print commands:

  % uni identify -f '%(script l:auto) %(cpoint) %(name)' 'a Ω'
  Script CPoint Name
  Latin  U+0061 LATIN SMALL LETTER A
  Common U+0020 SPACE
  Greek  U+03A9 GREEK CAPITAL LETTER OMEGA
  
  % uni list scripts
  Scripts:
  Name                    Assigned
  Adlam                         83
  Ahom                          54
  Anatolian Hieroglyphs        582
  …
  
  % uni print 'script:linear a'
  Showing script Linear A
       CPoint  Dec    UTF8        HTML       Name (Cat)
  '𐘀'  U+10600 67072  f0 90 98 80 𐘀  LINEAR A SIGN AB001 (Other_Letter)
  '𐘁'  U+10601 67073  f0 90 98 81 𐘁  LINEAR A SIGN AB002 (Other_Letter)
  '𐘂'  U+10602 67074  f0 90 98 82 𐘂  LINEAR A SIGN AB003 (Other_Letter)
  …
  

• Add "unicode" property, which tells you in which Unicode version a codepoint was introduced:

  % uni identify -f '%(unicode l:auto) %(cpoint l:auto) %(name)' a𐘂🫁
  Unicode CPoint  Name
  1.1     U+0061  LATIN SMALL LETTER A
  7.0     U+10602 LINEAR A SIGN AB003
  13.0    U+1FAC1 LUNGS
  

• Show unprintable control characters as the open box (␣, U+2423) instead of the replacement character (�, U+FFFD). It already did that for C1 control characters, and U+FFFD looked more like a bug than intentional. The -raw/-r flag still overrides this.

• Always print Private Use characters as-is for %(char) instead of using U+FFFD replacement character. It's usually safe to print this, and having to use -raw is confusing.

• ls command is now an alias for `list.

v2.5.1

• Fix build on Go 1.17 and earlier.

v2.5.0

• Add support for properties; they can be displayed with %(props) in -format, and selected in print (e.g. uni print dash).

• Add uni list command, to list categories, blocks, and properties.

• Allow explicitly selecting a block, category, or property in print with block:name (b:name), category:name (cat:name, c:name), or property:name (prop:name, p:name).

  Also print an error if a string without prefix matched more than one group (i.e. uni p dash matches both the property Dash and category Dash_Punctuation).

• Add table layout with -as table. Also change -json/-j to -as json or -as j. The -json flag is still accepted as an alias for compatibility.

• Change -q/-quiet to -c/-compact; -as json will print as minified if given, and -as table will include less padding. -q is still accepted as an alias for compatibility.

• Don't use the Go stdlib unicode package; since this is a Unicode 13 database and some operations would fail on codepoints added in Unicode 14 due to the mismatch.

v2.4.0

• Update import path to zgo.at/uni/v2.

• Add oct and bin flags for -f to print a codepoint as octal or binary.

• Add f format flag to change the fill character with alignment; e.g. %(bin r:auto f:0) will print zeros on the left.

• Allow using just o123 for an octal number (instead of 0o123). We can't do this for binary and decimal numbers (since b and d are valid hexidecimals), but no reason not to do it for o.

Release v2.3.0

• Update to Unicode 14.0.

• UTF-16 and JSON are printed as lower case, just like UTF-8 was. Upper-case is used only for codepoints (i.e. U+00AC).

• uni print can now print from UTF-8 byte sequence; for example to print the € sign:

  uni p utf8:e282ac
  uni p 'utf8:e2 82 ac'
  uni p 'utf8:0xe2 0x82 0xac'
  

  Bytes can optionally be separated by any combination of 0x, -, _, or spaces.

v2.2.1

Only one small change:

You can now use uni p 0d40 to get U+28 by decimal.

uni print 40 interprets the 40 as hex instead of decimal, and there was no way to get a codepoint by decimal number. Since codepoints are much more more common than decimals, leaving off the U+ and U is a useful shortcut I'd like to keep. AFAIK there isn't really a standard(-ish) was to explicitly indicate a number is a decimal, so this is probably the closest.

v2.2.0

Very minor bugfix release:

• Make proper use of the /v2 import path so that go get and go install work. (#26)

• Don't panic if -f doesn't contain any formatting characters.
