- UPDATE TO 4.5 USER DOCUMENTATION
- AND BUG/FEATURE FIXES SINCE 4.5 RELEASE
- Fri Nov 20 01:07:41 1992
-
- The ls.doc file has only been halfway updated to show all the changes
- since the 4.5ljr release. Please read this README file for full
- details. I've dragged my feet for a month now with regards to getting
- the doc file updated. It just isn't going to happen in the near future
- and thus I thought it better to release this now as is.
-
- Thanks to Dan B. and Chris W. for their recent help in getting some
- important bug and feature fixes into ls. Many others have helped
- since 4.5 by reporting problems and oddness when ls is used under
- 3rd party shells. [BTW, ls was operating correctly, but I have added
- a patch to ls that flushes Output() to work around limitations in
- some user shells.]
-
- Please read the manual if you have never read the LS 4.5ljr manual.
- Please read the following if you have read the manual.

-
- First release to be compiled with SAS/C v 6.0. Smaller and
- Faster. Way to go SAS! :-)
-
- --
-
- For me:
-
- Fixed bug that caused any format not ending in '\n' to have an output
- problem! Extra junk after some entries was being output.
-
- --
-
- Added for Dan:
-
- \" is now a valid way to include a quote on the command line. E.g.:
-
- <some command> `ls -fHF "\"%n\" "`
-
- will protect filenames with spaces in them.
-

-
- For Dan:
-
- Looked into problem related to removal of non-fixed disk while ls '-R' is
- scanning the media. Basically ls puts up one requestor per subdirectory
- in the current scan directory and then quits. Examine() / ExNext() appear
- to have some weirdness and don't respond with the correct error message.
- at least they don't set IoErr to the proper value under the OFS:
- IoErr() returns ERROR_NO_MORE_ENTRIES! even if the scan is interrupted
- due to disk removal --- what the hell? I'm leaving it alone.
-
- Did fix one bug, ls wasn't actually checking IoErr() when ExNext()
- quit returning entries!
-
- Fixed AsimCDFS CD-ROM file handler / ls interaction. ls had a bug. It
- didn't treat entries with non-listed filetype numbers as it should (I
- guess - things are a bit vague in this area, IMHO). ls was just being
- stricter than it should have been. Ls will now print any file entry with
- a negative (or =3) type number as a file. It will still only recurse
- into directories (>=0 & !=3) if they have a C= listed number.
- In the long listing, s and S appear in the file type field in place
- of - and d if special files.

-
- For Chris:
-
- [Filenote comments used to always come on the line following
- the long listing entry for the file it referred to.]
-
- The placement and way filenotes are displayed can now be modified
- by setting the ls_highlight0.on and ls_highlight0.off local
- environment variables (see subsection entitled, ``Environment
- variables'') and the format string (see subsection entitled,
- ``Formatted Output'') and the 'w' string. The default format
- string is "%p %5b %8s %d %n%w%C\n". The %C sequence is the place the
- filenote will appear in the output if requested with the '-c' option.
- If filenotes not requested or none present for a given file, %C
- expands to 0 characters, even if the highlighting strings are set to
- a displayable characters.
-
- '%w' is expanded to the current w (for whitespace? set via '-w' command
- line switch, e.g. ls -c -w " " ram:) string if %C would expands
- to a non-zero number of characters for the current entry.
-
- The %w string defaults to "\n".
- ls_highlight0.on defaults to "\x9b" "2m/* " and ls_highlight0.off
- defaults to " */\x9b" "22m". Thus all filenotes will appear on the
- line after the normal long listing entry in an alternate color in
- a C-style comment. E. g.
-
- R(0);T(00.266) > ls -c ram:a
- -----rwed c 1 0 Sep 30 22:37 a
- /* this file is neat */
-
- For example:
- R(0);T(00.000) > set ls_highlight0.on " /** "
- R(0);T(00.016) > set ls_highlight0.off " **/"
- R(0);T(00.000) > ls -cw " " ram:a
- -----rwed c 1 0 Sep 30 22:37 a /* this file is neat */
-
- BTW, %w and -w are a hack, pure and simple.
-
- --
-
- new formats for -F option argument:
-
- %C Print filenote comment if present and requested with '-c'.
- Filenote comment will have the highlight entry 0 applied to it
- (see comments given in section describing '-c' option) before
- printing. In general, highlighting (ANSI color sequences, etc.)
- should never be placed in the format string directly
- as it will not be filtered out correctly when ls is given the
- '-k' option or when ls is printing to a non-interactive device.
- In %C's case, this is especially important and in fact nothing
- related to filenote formatting should be included because not
- all files have filenotes and in any event they are not always
- printed.
-
- '%w' is expanded to the current w (for whitespace? set via '-w' command
- line switch, e.g. ls -c -w " " ram:) string if %C would expands
- to a non-zero number of characters for the current entry.

- New since 4.5ljr:
-
- 4.6ljr was an internal version that only fixed the Flush() 'problem'.
- I've been meaning to release an update to ls for a long time...
- ...been busy with new job and...
- ...been waiting for SAS/C 6.0 offical release [couldn't release *anything*
- based on it until the offical release.]
-
- --
-
- For various people:
-
- hack to Flush (Output ()) before ls terminates to allow some broken
- 3rd party shells to work with ls's use of 2.0's buffered IO.
-
- --
-
- For Dan:
-
- changing the hide pattern:
-
- [NOTE: No support for changing how 'h' protection bit based
- hiding works. It really doesn't seem worth the effort... :-)
- I don't have any '+h' protected files anyways. And, excluding
- files with other protection bit settings doesn't make a lot of
- sense IMHO.]
-
- "(#?.(info|bak)|.#?)" is the default hide pattern. This
- can be changed by setting the ls_hidepattern local environment
- variable (see subsection entitled, ``Environment variables'').
- For example, the following issued in a shell (or added to a
- shell-startup command file): set ls_hidepattern ".#?",
- would cause Amiga ls to function as a normal unix ls.
-
- --
-
- update list of ls_highlight#'s:
-
- With the advent of Amiga OS Release 2.04, there are now many more types of
- entries that can appear on a filing system (a disk). A number is
- associated with each entry type, e.g.:
- -4 is associated with a FILE LINK (hard link)
- -3 " " " PLAIN FILE
- -2 - -1 " " " NOT USED CURRENTLY
- 0 " " " (hack to provide a space for) FILENOTE (related highlighing)
- 1 " " " ROOT
- 2 " " " USER DIR
- 3 " " " SYMBOLIC LINK (soft link)
- 4 " " " DIR LINK (hard link)
-
- [the space for FILENOTE was always used this way, I just forgot to
- document this aspect in 4.5]
