how to use emacsclient -e "command" to convert a .org file to html?

Question

I want use emacsclient -e "command" to covert org mode file to html file, such as:

emacsclient -e "(org-html-export-as-html ./mynote.org)" > ./mynote.html

hope it will be save output to mynote.html file.
But I'm not familiar with elisp yet. Actually, org-html-export-as-html has many parameter I don't know how to use it.

Answer 1

A/ You can do it "yourself" with:

emacsclient -e "(progn (find-file \"file.org\") (org-html-export-to-html) (kill-buffer))" 

Caveat: to make it works you should have started Emacs with

emacs --daemon 

or if you already have an Emacs running, type M-x server-start

B/ use a github package

https://github.com/nhoffman/org-export

which creates some compiled lisp executables:

• org-export html
• org-export tangle
• ...

However my personnal experience is that the command line approach is faster.

C/ Bonus, tangling file

You can tangle files with the same command line approach:

emacsclient -e "(org-babel-tangle-file \"file.org\")"

Update, gives more details about C/

"tangling" is a term coined from literate programming

Literate programming (LP) tools are used to obtain two representations from a literate source file: one suitable for further compilation or execution by a computer, the "tangled" code, and another for viewing as formatted documentation, which is said to be "woven" from the literate source.[3] While the first generation of literate programming tools were computer language-specific, the later ones are language-agnostic and exist above the programming languages.

You have a unique file:

#+TITLE: My Org file

* Configuration

#+BEGIN_SRC bash :tangle yes :tangle "tangled.sh" :shebang "#!/bin/bash"
echo "This is my configuration script"
echo "..do something interesting here.."
#+END_SRC

You can html export it (parts A/ or B/), but but can also export the code it contains, here a shell script. From Emacs this can be done with C-c C-v t or, from shell, using the command I provided in C/ part. The result is the automatic generation of the tangled.sh file.

You can have a look here: Babel: active code in Org-mode for further details.

Answer 2

IMHO, correct way should be

emacsclient -e "(org-html-publish-to-html '()  \"file.org\" \".\")"

But it complains about *ERROR*: ‘org-publish-cache-get’ called, but no cache present - for me it looks like a bug in Org-mode
