It really works like charm and reading cld-mkiv.pdf is one of the things I want to do in the near future.

Hi Tomáš,
well, I wnanted to remove the ending period in both cases (and to
understand how that patterns might work.
I got the first one with:
context("2a ok. " .. url:match "[^/]+.+/") -- path and name
But I’m stuck at the second one (sorry, I don’t know how to remove the
final period):
context("2c. " .. url:match "[^/]+.$":match("^.+%l+[.$]"))
https://pragma-ade.com/general/manuals/cld-mkiv.pdf#search=nameonly is
the way to go, but it won’t hurt me to understand how patterns might
work here.
Many thanks for your help,
Pablo

Dear list,
I have the following sample:
\starttext
\startluacode
url = "../a/b/cb/ce.b/ca.b/c/dabc.pdf"
context(url)
context("0 ok. " .. url:match "^(.*).pdf$") -- name and path
context("1. " .. url:match "^(.*).+$") -- path
context("2. " .. url:match"[^/]+[.$]") -- name
context("3 ok. " .. url:match "[^.]+$") -- extension
\stopluacode
\stoptext
How can I get that match for #1 ends in the last slash (including it
"../a/b/cb/ce.b/ca.b/c/") and match for #2 ends in the last period
(excluding it, "dabc")?
it really helps to read the cld manual (or look into l-* files) as there
are plenty of efficient helpers for these things
local s = "./a/b/cb/ce.b/ca.b/c/dabc.pdf"
print(file.pathpart(s))
print(file.nameonly(s))
print(file.basename(s))
print(file.suffix(s))
print(file.replacesuffix(s,"tmp"))

Re: [NTG-context] getting path and filename from url
Hi Pablo,
is the following what you need?
context("1. " .. url:match ".+/")
context("2a. " .. url:match "[^/]+/.+[.]") -- path and name with period
--context("2b. " .. url:match "[^/]+[^.]+$") -- name with period and
extension
context("2c. " .. (url:match "[^/]+[^.]+$") :match ".+[.]") -- name with
period
Best wishes,
Tomáš
