* When ~ is parsed and next character is a delimiter, make sure contents of expanded $HOME match the user's delimiter. * When wildcard patterns don't match, rather than terminating the command gsh now prints "No match: <pattern> ignored" and passes the command line minus the unmatched patterns on to be executed. * Modified echo command so it doesn't add a blank to the end. * Make "clear" and "source" built-ins non-forked commands. Unforking "source" allows prefixes to be set in files that are sourced. * Add loop to parse a single command (removing leading whitespace) before sending it off to be expanded and executed. Skip null lines and comments at this level. This allows later commands that depend upon variables set in the 1st command to work; e.g.: set t_num=1 ; echo "Test number $t_num" Also fixes problems seen when tab was first character of multiple lines. * Initialize environment variable flags at startup (for echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof). Set flag when env var is set in upper or lower case (formerly, only worked with lower case). * Lots of places two-word addresses are incremented using inc, without checking for overflow into the high-order word. As these are discovered, they are changed to use adc on both words. See file UpdateLog for detailed list of changes.

|
Completed items are reported in file UpdateLog.
|
|
|
|
|
|
Initialize internal shell variables to match environment variables
|
|
(echo, nodirexec, nonewline, noglob, nobeep, pushdsilent, term, and ignoreeof)
|
|
when shell first starts.
|
|
|
|
Gsh requires the v2.0.4 ltermcap to link. Termcap has changed in v2.0.6,
|
|
and gsh should be updated to reflect this.
|
|
|
|
When building the EXE hash table, duplicate entries oughta should be ignored.
|
|
|
|
Make PATH's use consistent with forward parsing.
|
|
|
|
Identify limits built into gsh and how they can be changed; for example,
|
|
size of $PATH <= 256; max programs in hash table = 256.
|
|
|
|
Allow redirection of built-in commands' I/O even if they aren't forked.
|
|
|
|
When a background process finishes and there's text in the input buffer,
|
|
the next keypress correctly reprints the edit line but the key itself does
|
|
not get put in the buffer.
|
|
|
|
running a process in the background from inside a script (not 'source',
|
|
but executing the script as a command) causes the shell to wait for that
|
|
background process to end - not exactly what we want.
|
|
|
|
usage for alias and hash
|
|
|
|
job control monitor for defunct processes when waiting.
|
|
|
|
job control needs to save tty information.
|
|
|
|
Allow ~user construct (call routines to get user's home directory)
|
|
|
|
recursive aliases.
|
|
|
|
[ -- below this line...probably not -- ]
|
|
|
|
write new memory management.
|
|
|
|
coolish handling of setdebug by editor.
|
|
|
|
echo should use octal and hex \12 is dec, \012 is octal, \x12 is hex.
|
|
|
|
write history expansion.
