Hi Jan
Thanks for the feedback and advice. I am actually really only interested
in fish for writing scripts, I think this is where the syntax really
shines and hopefully this is the place for verbose but easy to read
code. I don't know sed that well so writing a wrapper will teach me
about it(I usually learn through failure) and if it works out I will
share here.
Have a great day-Patrick

Hi Patrick,
I agree with you that, like bash, sed syntax could use an improvement
(and so could awk, find, and other unix utilities from the old days).
For syntax, there are several properties that can be traded off:
consistency, readability, succinctness, and probably others. Lack of
consistency is often caused by adding new features over time, like
with bash. Readability and succinctness are partly a trade-off,
languages used interactively like shells need more of the
succinctness, while programs written to be reused need more
readability (e.g. in Python you always use parentheses to call a
function, in fish/shell you don't). Lack of consistency is often
caused by new features being added over time that weren't originally
plannen, or by 'design by committee'.
I think your proposal with -in_regex / -out_regex is way to verbose
for interactive use, though it is probably more readable that way
compared to /complex/ sed clauses (the s/day/night/ is simple enough
for me).
Good languages nearly always had one person that took all the design
decisions, so if others are willing to help you, don't try to form a
design committee. Also, successful open source projects are usually
started with someone who writes a minimally working prototype, and
then attracts the attention of others, not by having only a good idea
and asking others to help without there being any code to start with.
That way you will mostly get a lot of people who have other ideas and
advice, but are not actually interested or motivated enough to get
busy with the code (case in point: me right now. While the idea is
nice, I don't have time to invest in coding on this).
Also note that many people use shell on a daily basis, but specific
tools like sed are used much less often (at least speaking from my own
experience). Also, more and more I see people advise that if you write
a shellscript longer than five lines, switch to python or ruby, so
larger shellscripts in which sed is a common component are getting
less popular. Given that, compared to bash, the fish community is very
small, I think the number of people who'd go through the trouble to
install a better sed is very small.
On the other hand, a sed is much easier to write than a shell, so just
go ahead and make something, and see if it gets any traction.

Hi Everyone
I am only an enthusiast programmer and truthfully I have not done much
with shell scripting, before realized what fish was about the syntax
freaked me out. Sed also freaks me out, again due to the syntax.
Do you
think it would be in keeping with the goals of fish to create a
wrapper
around sed to make it more friendly(and verbose).
For example:
echo daytime | sed 's/day/night/'
perhaps could be:
echo daytime | fsed -s -in_regex 'day' -out_regex 'night'
This is nearly useless for this example but perhaps might help
once more
complex options were involved? Has this already been done, is it
useful?
BTW I emailed Axel on github, hopefully I'll hear back.
Thanks-Patrick
