* - Added support for backreferences in substitution expressions up to nineMark Whitley2000-07-172-36/+152
| | | | | | | | | | | | | | | (\1, \2...\9). This touched a lot of places in this file and I added a new function 'print_subst_w_backrefs' in order to keep 'do_subst_command' a little more tidy. * I tested this good 'n hard, but will always appreciate more testing from other, willing folks. - Noticed that the index_of_next_unescaped_slash was subtly wrong so I changed both the functionality and behavior (it used to skip over the first char in the string you passed it, assuming it was a leading '/'--this assumption is no longer made) this necessitated changing the lines that call this function just slightly.
* Now it's possible to compile Busybox with only one app definedPavel Roskin2000-07-172-15/+21
| | | | (unless it's lsmod, to be fixed by the next commit)
* Backtick support to infinite (memory limited) levels of nesting isEric Andersen2000-07-173-90/+255
| | | | | | | | | | | | now implemented... So now busybox shell can do cool stuff like: /home/andersen/CVS/busybox # echo foo `wc README` bar foo 71 422 2951 README bar I love writing cool new features.... Muhahahaha... (I think this is leaking a little bit of memory every time it expands a backtick process, so I still needs to do a bit of cleanup...) -Erik
* It is now possible to select in busybox.def.h whether minixfs version 2Pavel Roskin2000-07-175-72/+63
| | | | is to be supported.

|
* Don't use strings directly in calls to usage(). This is in preparationMatt Kraai2000-07-1431-289/+321
| | | | for their extraction to a separate file.
* Fixed a couple of buglets:Mark Whitley2000-07-142-12/+58
| | | | | | | | | | | | | | | | - add_cmd_str: segv's were being generated if there was a '# comment' line (and probably other kinds of lines, too) that was not followed by a semi-colon or whitespace - parse_edit_cmd: was returning a wrong number (too low) for the index; it was not accounting for backslashes eaten, for the fact that we start at the 3rd index in the string, or for the fact that we add an extra newline. - parse_cmd_str: was returning a wrong number (again, too low) for the index in the case of single-letter commands (p,d). There was some over-compensation for this in the 'return' stmt at the end which also needed some help. - load_cmd_file: was not eating trailing newlines off the line read from the command file. This had the deleterious effect of printing an extra newlines after text displayed from edit (i,a,c) commands.
* - Added support for semicolon delimited command lines. (woo-hoo!)Mark Whitley2000-07-142-62/+144
| | | | | | | | | - Obsoleted the trim_str function (#if 0'ed out -- maybedelete later) in favor of strrspn. - Obsoleted the strrspn function (#if 0'ed out as well) as soon as I discovered that it wasn't needed either. - Fixed a subtle bug in parse_subst_cmd where it would choke with an error if there was any trailing space after the s/match/replace/ expression.
