hello people,
some of the things i really enjoy in zsh comes from rc
(setopt rcquotes, the ^ expansion, the alternative syntax
for constrol structures that are close to rc, ...) but
both the codebase and the binary are very large.
i'm experimenting replacing zsh by rc when the rc
counterpart is good enough. but it seems i reach the
limits of rc very soon. example
in an mkfile, i can write things like that
PUBLIC = `{ echo *.md }
PAGES = ${PUBLIC:%.md=pub/%.html}
in zsh, i can write
ls *.md
set -- *.md(:r) # (:r) will remove the tailing .md
pages=( pub/$^@.html )
print -l $pages
as a result, i get
l'autre.md
this is.md
pub/l'autre.html
pub/this is.html
there is nothing like the ':' modifiers or ${p%.md}
alike expansions in rc so i try to figure out what
would be an idiomatic way to do that in rc.
i tried
pages=(`{ ls *.md | sed 's/md$/html/; s/md''/html''/' })
echo pub/^$pages
which gives me
pub/l'autre.html pub/this pub/is.html
close ... but wrong :) i can add klugdes around it but i
feel i missed something. Any advice when it comes to applying
a transformation to a list with rc?
regards
marc
