Stata commands in Python

[Ulrich Kohler]

Dear all,

I am using Ben Jann's -texdoc- to write some text about the integration of Python in Stata. In this text, there is the following structure:

Some LaTeX  that explains Stata and Python. 

***/
texdoc stlog
python
from sfi import Data
end
texdoc stlog close 
/***

some following up LaTeX 

***/
texdoc stlog
python
myname = Data.get("ybirth")
end
texdoc stlog close 
/***

This works in the sense that it runs withouth errors. However, in the PDF that is finally produced, I get:

Some LaTeX that explains Stata and Python.

. python
. from sfi import Data
. end

some following up LaTeX

. python
. myname = Data.get("ybirth")
. end

Instead of this, I would like -python- to be called only once at the beginning, and -end- only once at the end. Is there a way to achieve this?

My idea was to use -stata.run()- from -pystata- to issue the commands -texdoc stlog close- and -texdoc stlog- from the python environment:

. python
>>> import stata_setup
>>> stata_setup.config('/usr/local/stata18','se')
>>> from pystata import stata
>>> stata.run("texdoc stlog")

but stata.run() crashes the running Stata 18 instance (Linux Ubuntu). I guess -pystata- just isn't meant to be run from within a python environment started within Stata.

Does anybody have another solution? (This is a larger project that went quite far already, so working from Python completely, or getting rid of -texdoc- is not really an option)

Many regards
Uli

Maybe a brute-force add "tags" and (regex) search-replace in *.log.tex files might be considered if you do not find another solution, some variant of:

texdoc stlog
* remove_python 
python
2 + 2
print("remove_end")
end
texdoc stlog close

.log.tex

. type "`fn'"
. * remove_python 
. python
\HLI{47} python (type {\bftt{end}} to exit) \HLI{81}
>>> 2 + 2
4
>>> print("remove_end")
remove_end
>>> end
\HLI{155}
{\smallskip}

Example remove both "python" and "end":

local fn "myexample_3.log.tex"

qui di filewrite("`fn'", ///
    ustrregexrf(fileread("`fn'"),  ///
        "(?ms)\* remove_python.+?(?:(?!>>>).)*","") ///
    , 1 ////
    )
    
qui di filewrite("`fn'", ///
    ustrregexrf(fileread("`fn'"),  ///
        "(?ms)^>>>.*remove_end.+end.*?$.","") ///
    , 1 ///
    )
 
cat "`fn'"

. >>> 2 + 2
4
\HLI{155}

or add option to texdoc.ado, similar to stlogoption matastrip (see mata functions _texdoc_striplog_mata() and _texdoc_striplog_mata_end() )

Dear Bjarte, thank you very much for this. This is awesome!
