Subject: | Re: [O] [Discuss] make :tangle header argument respect :dir could save info typing |

I realized one thing, the combination of ~:mkdir~, ~:dir~, and ~:tangle~ does not work
good enough. Can make ~:tangle~ respect ~:dir~ too. WDYT?
Here is an example:
#+begin_src clojure :mkdirp yes :dir "data/code/clj-crawler-demo" :tangle "src/clj_crawler_demo/core.clj"
(ns clj-crawler-demo.core
(:require [clj-http.client :as http])
(:require [net.cgrand.enlive-html :as html]))
(html/select
(-> (http/get "https://www.baidu.com")
:body
html/html-snippet)
[:div])
#+end_src
Why need this? If ~:tangle~ respect ~:dir~, it will don't need the complete path to
tangled file. And when the source block has other header argument need dir like
~:file~, this will make ~:tangle~ and other related header arguments shorter.
If ~:tangle~ does not respect ~:dir~, user need to repeat the path:
#+begin_src clojure :mkdirp yes :dir "data/code/clj-crawler-demo" :tangle "data/code/clj-crawler-demo/src/clj_crawler_demo/core.clj"
(ns clj-crawler-demo.core
(:require [clj-http.client :as http])
(:require [net.cgrand.enlive-html :as html]))
(html/select
(-> (http/get "https://www.baidu.com")
:body
html/html-snippet)
[:div])
#+end_src
This is long, I know there is ~#+headers:~ for source block. But reduce info would
be better. I also consider the disadvantage of this change. Some user's existing
source block might be broken.
Let's level this change for discussion.
