Big late 1990s question: Will MS Word replace LaTeX? It never did!




MOOCs, Kahn Academy, ndla, H5P, Haiku Learning, Opigno, ...


LaTeXforpaper and HTMLforscreen are two very different writing styles and technology platforms.
What tools should I use for scientific writing?








Suppose I write various types of scientific material,
and later want to collect the pieces into a larger document, maybe some book  is that at all feasible?
Probably not, but I have a solution

Highly nontrivial to translate from/to LaTeX!
I am used to write LaTeX paper/bookstyle with lots of crossreferences and floating figures, code snippets, tables, algorithms, but now I want to convert to IPython notebooks.
Must have fixed figures, code snippets, tables. No algorithm environment, crossreferencing, equation referencing. All code needed for a snippet to run must be included. It's a different writing style, but lots of new opportunities.

environment,
recall that Sphinx, Markdown, and MediaWiki cannot handle this,
although they have LaTeX math support.
DocOnce offers minimalistic typing, great flexibility wrt format, especially for scientific writing with much math and code.

At any time one can divorce from DocOnce and marry one of the output formats, such as LaTeX or Sphinx. The generated code is clean.

Result:
This is a paragraph heading.
* Bullet list items start with `*`

* *Emphasized words* are possible
* _Boldface words_ are also possible
* color{red}{colored words} too
* `inline verbatim code` is featured
o and sublists with enumerated items starting with `o`

Inline math as in LaTeX:
...where $a=\int_{\Omega}fdx$ is an integral.
gets rendered as ...where \( a=\int_{\Omega}fdx \) is an integral.
An equation environment is surrounded by !bt

tags,
the rest is plain LaTeX:

\frac{\partial u}{\partial t} &= \nabla^2 u,
label{a:eq}\\
\nabla\cdot\pmb{v} & = 0
label{b:eq}
\end{align}

dt = float(dt); N = int(round(T/dt)); T = N*dt

u[0] = I
for n in range(0, N):
u[n+1] = (1  (1theta)*a*dt)/(1 + theta*dt*a)*u[n]

This gets rendered as

return u, t
We recommend to copy as much code as possible directly from the source files:
@@@CODE path/to/file
@@@CODE path/to/file fromto: startregex@endregex
For example, copying a code snippet starting with def solver(
and
ending with (line not included) def next(x, y,
is specified by
start and end regular expressions:
@@@CODE src/somefile.py fromto: def solver\(@def next\(x,\s*y,

label{demo:ex:1}
files=flip_coin.py, flip_coin.pdf
solutions=mysol.txt, mysol_flip_coin.py
keywords = random numbers; Monte Carlo simulation
!bsubex
Make a program that simulates flipping a coin $N$ times.
!bhint
Use `r = random.random()` and define head as `r <= 0.5`.
!ehint
!esubex
!bsubex
Compute the probability of getting heads.
!bans

!eans
!esubex
a) Make a program that simulates flipping a coin \( N \) times.
Hint.
Use r = random.random()
and define head as r <= 0.5
.
b) Compute the probability of getting heads.
Answer. 0.5.
Filenames: flip_coin.py
, flip_coin.pdf
.
All exercises, problems, and projects in a document are parsed and available in a data structure (list of dicts) for further processing (e.g., making a book of problems).

===== Headline =====
* Key point 1
* Key point 2
* Key point 3: Although long
bullet points are not recommended in general, we need
it here for demonstration purposes to investigate
what happens with the slide layout where there is
so much text under one point

work in Wordpress :)
For wordpress, add wordpress
:
doconce format html doconcefile wordpress
and paste the code into the text area.
doconce format pdflatex doconcefile latex_code_style=lst
pdflatex doconcefile
bibtex doconcefile
pdflatex doconcefile
doconce format sphinx doconcefile
# Autocreate sphinx directory
doconce sphinx_dir theme=pyramid doconcefile
# Copy files and build HTML document
python automakesphinx.py
googlechrome sphinxrootdir/_build/html/index.html
Much easier than running the Sphinx tools manually!
Only MediaWiki supports math.
