[0.5] vis version 0.5 - 2018-03-25

• Fix for a buffer overflow when dealing with invalid/incomplete Unicode sequences which caused an infinite loop/crash. With default compilation flags this should not be exploitable, but opening a malicious file would lose all unsaved changes.

• Fix color support in ncurses 6.1

• New default 256 color theme: zenburn. It should hopefully work better with the default color palette.

• Updated Docker based builds (make docker) to use latest Alpine Linux packages to produce a statically linked, self-contained binary.

• Take symbolic keys into account when evaluating key prefixes (ci< is not a prefix of ci<Tab>).

• Improved paragraph text objects.

• Reset count after handling ,

• Lexer updates for Clojure, Scheme, ASM, Pony, PHP, Python, Erlang, xs and ReasonML.

• Correct handling of g/^$/ construct to match empty lines in commands like:

  x g/^$/ d

• <C-v><Enter> now inserts \r rather than \n, this currently also affects r<Enter> which might not be desirable.

• Fix command prompt malfunction triggered by special cursor position.

• Configure script can be interrupted.

• Removed ! operator, use :|

• Ignore SIGQUIT

• vis-open(1) fixes

[0.4] vis version 0.4 - 2017-07-23

• Selections as core editing primitives. Cursors have been superseded by singleton selections. Overlapping selections are now merged. This change is also reflected in the exposed Lua API (for which still no stability guarantee is given).

• Selections can be saved into marks on which set operations can be performed:

  m save selections
  M restore selections
  | set union
  & set intersection
  \ set minus
  ! set complement
  z| pairwise union
  z& pairwise intersection
  z+ pairwise combine, choose longer
  z- pairwise combine, choose shorter
  z< pairwise combine, choose leftmost
  z> pairwise combine, choose rightmost

  Marks are specified using '{mark} analogous to "{register}.

• Jump list based on marks:

  g< jump backward
  g> jump forward
  gs save currently active selections

• New register # to insert the current selection number.

• Drop special handling of \r\n line endings. \r will be displayed as ^M. Enter will always insert \n.

• Fix Unicode regex search with libtre backend.

• New count specifiers for sam's g and v commands to keep/drop selections based on their index.

• On macOS saving files larger than INT_MAX bytes should work.

• New :set show-eof to toggle the display of end of file markers ~ as before it is enabled by default.

• Double leading slashes of paths are stripped.

• Improved :< command implementation to only use a pipe when necessary.

• New lexers for Myrddin and strace(1), updates for Elixir, Perl and Forth.

• Fix compilation for GNU Hurd. The vis package is now built for all supported Debian architectures.

• Improve job control of forked processes. SIGINT is now properly delivered to child processes.

• Commands given a huge count can now be interrupted using .

• This is implemented in cooperative fashion, meaning a single long running operation can still not be interrupted.

• More efficient line wise motions based on optimized mem{r,}chr(3) libc functions.

• Optionally support vim compatible n/N search direction.

• Reproducible, statically linked, self contained binary built using the Alpine Docker image. The idea being that it is a single file which can be copied to any Linux >= 2.6 system to provide a usable editor. It has an embedded tar archive which contains the required Lua support files which are extracted to a temporary directory using libuntar.

• Preliminary C API documentation found at: http://vis.rtfd.io

• Updated manual page.

• Various code cleanups.

Check the git log for further details.

[0.3] vis version 0.3 - 2017-03-26

Most notable changes include:

• support for sam's structural regular expression based command language
• various bug fixes related to multiple cursor/selection support. New functionality to navigate among cursors (<C-u>, <C-d>), align (<Tab>, <S-Tab>), rotate (+, -), trim (\) or drop (<C-c>, <C-l>) selections.
• improved Lua API, featuring a new event subscription mechanism and the possibility to define custom operators, motions, text-objects, :set options and more. Notice however that at this point no API stability guarantee is provided.
  You might have to update your visrc.lua configuration file, check the Documentation for details: http://martanne.github.io/vis/doc/
• new standalone tools vis-menu (:o .), vis-digraph (<C-k>) and vis-complete (<C-k>) for a simple file open dialog, digraph support and word completion, respectively.
• multiple bug fixes for vi(m) functionality, including improved count and repeat handling as well as better cursor positioning, cw, shift, join and autoindent implementation.
• new key mapping processing based on longest unique match
• optional libtre based regex backend for more memory efficient forward searches
• respect umask when creating new files, previously they were only read/writable by the current user. Also fsync(2) destination directory after rename(2) when performing an atomic save operation.
• new :set options to configure the used shell, escape delay, file save method and context to consider for syntax highlighting
• True color support in lexer themes, in case the terminal supports color palette changes
• minimal built-in :help [pattern] command
• incorporated upstream changes to LPeg based lexers used for syntax highlighting from the Scintillua project
• new set of manual pages in mdoc format
• experimental raw vt100 UI backend for resource constraint environments
• various code cleanups and bug fixes reported by static analysis, runtime interpretation and fuzzing tools
