psh-0.005 - Perl SHell - metacpan.org

Changes for version 0.005 - 1999-12-28

A very functional release.
New Evaluation Strategies
- brace
- fallback_builtin
  - Builtins of this type (currently searched in package `Psh::Builtins::Fallback') will be executed AFTER no program of that name was found. This allows simulation of common commands like ls and env on systems not having such binaries.
- auto_resume
New Bultins
- builtin
- env
  - On systems with an env binary installed it will use the binary, on other systems (namely Win32) it will print a list of environment variables.
- help
- unalias
Builtin Enhancements
- alias
  - Changed builtin alias so that '`alias name'' displays the alias definition for that name.
- bg
  - It's now possible to do '`bg commandname'' (e.g. '`bg emacs'') fg has the same behaviour for consistency.
- cd
  - Respects `CDPATH' now and sets `OLDPWD'.
Portability Enhancements
- Added portability infrastructure.
- Working Win32 port (though it has limited features).
Completion Enhancements
- Variables for bookmark completion are now `@Psh::Completion::bookmarks' and `@Psh::Completion::netprograms'.
- New Perl Hashkey completion will TAB complete the name of keys for Perl hashes (if they are not written in quotes).
- Support for user defined completions by `%Psh::Completion::custom_completions'.
- Perl Symbol completion now supports package names and package name completion.
- Support for TAB completions for builtins.
- A `custom_completions' entry may now also be code. If the value of a `custom_completions' key/value pair is a `sub' that `sub' will be called and the result used as rules.
- A rule for `custom_completions' may now have an optional third argument. If that argument is true, the `custom_completion' will replace the standard completions instead of adding to them.
- Filename Completion respects the `FIGNORE' environment variable now.
Other Changes
- Documentation updates.
- Locales defined for: Default (English), French, German, Italian, Portuguese, and Spanish.
- New fallback builtins: ls
- Prompt evaluation is now more bash compatible and handles even more complex prompts.
- Replaced `Psh::OS::Unix::glob()' - now uses its own glob routine instead of `CORE::glob()' - and is significantly faster (important for executable completion).
- New variables: `$Psh::Prompt_cont', `$Psh::result_array'.
- Moved almost all code from `psh' into `Psh', `Psh::Builtins' and `Psh::Util'.
- Environment variable `CURRENT_SHELL' is set to the path to psh.
Bug Fixes
- Generation of weekday names.
- Small fixes for setenv, print_list and abs_path.
- Fixed signal description generation.
