- Short: Amiga stream editor
- Author: thor@math.tu-berlin.de (Thomas Richter)
- Uploader: thor@math.tu-berlin.de (Thomas Richter)
- Version: 40.2
- Type: util/cli
- Requires: AmigaOs 3.0 or better
-

- Purpose of this program:
-
- SED takes an input file, checks each line of this file against a
- pattern supplied on the command line, and generates a new line from
- this pattern match in the destination. This could either mean that
- the matching line is removed completely from the output, replaced
- by a different line, or changed according to the specifications of
- SED.
-
- SED is an approximation of the Unix "stream editor" sed. It is not
- quite as powerful as sed because its command set is currently very
- limited, and it does not support command files. Its pattern syntax
- is different, too. It still looks like "line noise" to me - I didn't
- want to break with this tradition - but it's at least the Amiga kind
- of line noise.
-
- Its pattern matching rules are a superset of the AmigaOs patterns,
- with some additional features like "captured expressions" and more
- powerful "character classes" and "escaping".
-
- SED is useful for automatic processing of text files, e.g. the modi-
- fication of the startup-sequence. SED can also be run as a "filter"
- in which case it reads its input from stdin and prints output to
- stdout. Combine this feature with pipes and you get a very powerful
- text processing tool.
-
- A warning: Pattern matching looks simple, but is full of hard to gasp
- traps. This tool is therefore thought to be for "expert usage". In
- case you think SED doesn't process your pattern correctly, think
- twice!
-
- For further details, please read the SED.doc.

-
- Release 40.2:
-
- Due to an oversight, the character ranges [..-..] were broken.
- Fixed.
- Handling of (..|..) "or-operator" was broken. Fixed.
- Escaping with \ could leave bogus patterns in the pattern stream
- and could have caused non-justified "invalid template" errors.
- Fixed.
-
- ______________________________________________________________________________
-
- Release 40.1:
-
- The former release used memory pools, but did not check correctly
- whether the corresponding exec functions are available. Required
- and requires Kickstart 3.0.
- Could have forgotten to return "ERROR_NO_FREE_STORE" for some
- out of memory error conditions.
-
- ______________________________________________________________________________
-
- Release 40.0:
-
- This is the first Aminet release. This is a 40.0 release because
- pattern matching is a very complex buisiness and even though I tested
- this release quite good, I wouldn't be astonished if some flaws still
- remained. Pattern matching logic is astonishing sometimes, so please
- check the documentation first before reporting any "obvious" bugs. The
- obvious bugs should be gone already!
