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.

v2.1.0

• Can now output as JSON with -j or -json.

• -format all is a special value to include all columns uni knows about. This is useful especially in combination with -json.

• Add %(block), %(plane), %(width), %(utf16be), %(utf16le), and %(json) to -f`.

• Refactor the arp242.net/uni/unidata package to be more useful for other use cases. This isn't really relevant for uni users as such, but if you want to get information about codepoints or emojis then this package is a nice addition to the standard library's unicode package.
