NAME

Change log for psh - The Perl SHell

DESCRIPTION

A reverse-chronological ordered list of changes

0.008 [2000-04-30]

New and Enhanced Built-ins

cd and dirs

The cd builtin now has a (currently unlimited) history list, accessible using:

cd -/+/%number

The new builtin dirs displays the stack.

complete

Adds a mightier and bash compatible way to define custom completions.

firsttime

A firsttime user setup utility for the .pshrc file. It cannot do a lot currently but will grow in future.

function

Tries to emulate bash's behaviour.

history

unalias

Does not remove builtins of the same name anymore.

New Features

• Extended Completion code for Perl (supports $#foo, $foo->{key, $foo->method, subroutine without &, perl reserved symbol)

• Executable completion now even after initial ! for shell escape

• Some minimal status code testing and error handling for user input.

• Understands environment variable $IGNOREEOF.

• Accepts the -i command line switch and ignores it for bash compatibility.

• If the line you entered matches the last line it won't be added to the history.

• On Unix, support for a global .pshrc file at /etc/pshrc.

• New variable @Psh::executable_noexpand.

• New variable $Psh::interactive which is set if psh is currently in interactive mode.

Bugs Fixed

• Fixed some small problems with globbing code.

• Fixed problem with pod2man and CHANGES.pod reported on Sourceforge.

• SIGTERM and SIGHUP are not ignored anymore and cause psh to exit instead.

• Switch -r now reserved for restricted mode, new switch -f for alternative resource file.

• Fixed problem with quoting which was not removed for the executable strategy.

• Piping is now possible in aliases.

• The parser now allows nesting aliases.

0.007 [2000-02-14]

Contributions primarily by Markus Peter (warp) and Simon Huggins (huggie).

New Features

• Support for window titles. New environment variable $PSH_TITLE, $Psh::change_title, $Psh::window_title. The behavior is like prompt strings.

• Strategy perlfunc is a default strategy again. $Psh::perlfunc_builtins determines wether Perl builtins should be evaled (default 0)

• Builtin kill now supports sending a signal to a named job (e.g. "emacs & ; kill emacs").

• Builtin strategy for loading strategies on demand and adding them to the list of strategies to use. Handy for strategies that are used less often than the core strategies.

• Properly pipeable aliases.

• Fallback and most other builtins are loaded on demand.

• Converted &Psh::symbols() into a builtin, symbols.

• New builtin set. Acts like bash's set and returns environment. Could be extended to allow set -o noclobber bash-isms to work.

• New strategy auto_cd.

• Builtin strategy now knows command available to list available strategies

Bug Fixes

• The Unix resize handler now works correctly in big xterms.

• Added print "\n" on CTRL-C to clean up display.

• Fixed generation of $Psh::history_file.

Other Changes

• Added README.perl5.004 to explain about File::Spec

• Strategies fallback_builtin and perlfunc modularized and moved into Psh::Strategy::*

• Perlfunc configuration variables are now in Psh::Strategy::Perlfunc for cleanliness.

• Removed &Psh::news() since there's no need for it being included in psh just for the tryme script.

• List of builtins for which autoloading is supported is built automatically during startup.

0.006 [2000-01-03]

Refinements to 0.005.

New Features:

• New builtin delenv.

• Builtin kill accepts multiple PIDs.

• Saving the history file now respects $Psh::history_size if Term::ReadLine::Perl is used

• Manifest Filters for pipeline code, e.g. try:

  ls | s/y/k/                      # Substitution. Example is a Y2K fix.
  ls | { print ++$i, ": $_"; }q    # Quick. Iterate over lines.
  netstat | { $_[1]>2; }g          # Grepish. Print line if { ... } evaluates to true.

  See the psh documentation for more information.

• New recursive globbing using **/ (Example: grep anything **/*.pm).

Win32 Port Enhancements:

• It now works. 0.005 was missing a couple of patches.

• Makes use of system registry.

• Implementations of execute_complex_command(), get_hostname(), get_all_users(), get_home_dir(), and get_known_hosts().

Internals:

• Moved prompt code and perl evaluation code into own packages.

• Implementing redirects and pipes in psh.

• Clean-ups for all code using filenames (now using File::Spec).

• More I18N.

• Removed usage of $ENV{HOME} in portable code.

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.

0.004 [1999-12-13]

This release fixes bugs, refactors the code, and adds the following features:

• Background process management much more like bash.

• Perl code in addition to executables may be put in the background.

• Pipelines.

• Initial internationalization.

• New built-ins: alias, export, setenv.

• A flexible set of evaluation strategies that can be selected or reordered by setting a configuration variable.

• Prompt strings can have escapes like \07 (ASCII BEL) or \10 (ASCII LF).

• avoided trying to save history if there wasn't even a ReadLine module.

• added $psh::debugging variable to hold the debugging state, so it can be turned on and off in a running psh.

• A $psh::echo variable to control whether perl results of evaluation are printed.

• The which builtin now shows which strategy will apply to a given command line

• Grab more input automatically if <<BLOCK appears anywhere on the line, or if the line ends with an open brace.

• results of &psh::which() searches are hashed.

• Thorough documentation of every user-accessible variable and function

0.003 [1999-11-23]

Contributions from Markus Peter:

• Rudimentary background jobs handling and job management.

• Signal handling.

• Filename completion.

• Updates to history handling.

• Flexible %built_ins mechanism for adding built-in functions.

• Smart mode is on by default.

0.00205 [1999-11-08]

• Changed prompting to pass prompt string into &iget(), which passes it on to &Term::ReadLine::readline() or prints it out if the ReadLine module is not available. Thanks to Sam Tregar and tmb at lumo.com.

• Changed history handling so that empty lines and those consisting of entirely whitespace are not recorded.

• Fixed a couple of typos.

• Changed the regular expression for `smart mode' to allow vi +3 psh in addition to ls -l.

• Now uses Getopt::Std for option processing.

• Fixed the code that detects the presence of Term::ReadLine.

• Made more use of debug mode to print out advisory information.

• Use zero instead of undef to set Term::ReadLine::MinLine so that we don't get undef usage trouble in the guts of Term::ReadLine::Gnu.

0.00204 [1999-11-01]

• Added a bunch of stuff to the TODO file.

• Added parens around each part of the $interactive detection expression.

• Prompt variables are now dealt with via %prompt_vars, which can be modified, so that custom prompt variables can be created.

• Added %built_ins.

0.00203 [1999-08-28]

• Fixed typo that caused a bug where prompt variable $ didn't work. Thanks to John Labovitz.
