Announcing: CShell 5.10
CShell 5.10 offers a much more powerful parser, some new command options
and bug fixes.
Main features include: (see changes.doc for complete list)
- totally rewritten parser, therefore:
- local variables, in aliases as well as in batch files
- blocks can be formed, redirected, aborted: {e yo;e ho}
- $(foo) will insert output of program foo at that point, similar: `foo`
- parsing also done with command itself, e.g. '*' is a legal command line
- aliases/foreach/forline/fornum/source can be redirected as a whole
- direct recursion in aliases prevented, 'alias ls "ls -s"' works
- additional speedup; twice as fast as 4.xx, four times as fast as c:Execute
- 'assign' now can handle all types of assings correctly under 2.0
- 'class' can pattern-match now, e.g. 'class sound name="mod.*"'
- 'copy' has a larger buffer, copy -m' moves files
- 'dir -z formatstring' is a very powerful formatting feature, some more opts
- 'forline i STDIN' reads args from stdin
- 'man' can handle multiple .doc files, so you can document your own aliases
- 'source' can handle multiple line blocks of arbitrary length
- 'rback'/'run' now set the variable '$_newproc' to the # of the new process
- $_abbrev can be used to disable abbreviation if internal commands
- $_ioerr contains the secondary return code after an error
- $_pipe now holds the directory for the temporary pipe files
- $_verbose need to be set to special values, now can trace alias calls
- @console tells whether stdin or stdout are interactive
- @ioerr converts a secondary error number to a string (like 'Why')
- @mounted indicates whether a device has been mounted yet or not
- @sortnum sorts its arguments numerically
- shift-arrow-up and shift-arrow-down now behave like under AmigaDOS
- concatted lines in source files can be arbitrary long
- . now stands for current directory, .. for parent
Most important bug fixes:
- INTERNAL residents can now be used with V37 Kickstarts
- c:Execute can be started
- 'Wait 5&' as an alias for 'rback Wait 5' now works
Miscellaneous info:
- Some more documentation, tips & tricks
- Executable size: 89K
Available now from ab20.larc.nasa.gov, will be distributed over
comp.binaries.amiga.
