Re: [ast-users] including newlines & tabs in extended getopts text?
happy new year
the ast tw command has an EXAMPLES section you can examine by
tw --usage 2>&1 | fmt -o
try something like
[+EXAMPLES]
{
[+tw?Lists the current directory tree.]
[+tw chmod go-w?Turns off the group and other write permissions
for all files in the current directory tree using a minimal
amount of \bchmod\b(1) command execs.]
[+tw -e \"uid != \'bozo\' || (mode & \'go=w\')\"?Lists all
files in the current directory that don\'t belong to the user
\bbozo\b or have group or other write permission.]
}

[ast-users] segfault in child shell--debugging steps?
i've been seeing a fairly consistent segfault in ksh93u when running as a background child process of another ksh93u instance. i haven't had the time to do a full investigation yet, but it seems to be crashing inside the memory manager. i'm planning on running the script in question under valgrind to verify exactly what's going wrong, and then submit the logs here. is this a reasonable approach? anything else i should do? -- Aaron Davies aaron.dav...@gmail.com ___ ast-users mailing list ast-users@lists.research.att.com http://lists.research.att.com/mailman/listinfo/ast-users
[ast-users] including newlines & tabs in extended getopts text?
is there a way to drop down a single line (and add a tab) in a man section defined in an extended getopts text? e.g. the traditional way to format an EXAMPLES section seems to be command -xyz 1 foo descriptive text (with the example itself in bold) but i can't figure out how to do that from a [+name?text] group e.g. in ~ :) % /bin/cat ./foo.ksh #!/usr/bin/env ksh while getopts $'[-][+EXAMPLES?\bcommand -xyz 1 foo\b\ndescriptive text]' opt do : done ~ :) % ksh --version version sh (AT&T Research) 93u 2011-02-08 ~ :( % ./foo.ksh --man EXAMPLES command -xyz 1 foo descriptive text SYNOPSIS ./foo.ksh [ options ] ~ :( % the newline and the tab disappear (when i use --??nroff and generate a typeset manpage, the bold comes out correctly) -- Aaron Davies aaron.dav...@gmail.com ___ ast-users mailing list ast-users@lists.research.att.com http://lists.research.att.com/mailman/listinfo/ast-users
