extract v1.8

This package can be used to (conditionally) extract specific
commands and environments from a source file and write them to a
target file. This can be done without significant changes to the
source document, but labels inside the source can be used for more
flexibility. The package also provides environments to write code
directly to the target file or use code in both the source and the
target file. These tools allow one to generate ready-to-run files
from a source document, containing only the extracted material, in
an otherwise ordinary LaTeX run. See for more information the pdf
documentation of this package.


First check whether this package can be installed by the distribution
that you use, since that will simplify installation. For manual
installations, the structure and supposed location in a TDS compliant
TeX-tree is shown in the overview below. In words, extract.sty should
be available to LaTeX. Don't forget to update your filename database
after installing the files.

CTAN:/macros/latex/contrib/extract: official location
 |- readme     : should not be installed
 |- extract.dtx: /source/latex/extract
 |- extract.pdf: /doc/latex/extract
 `- extract.sty: /tex/latex/extract

The package includes pregenerated run and doc files, but you can
reproduce them from the source if necessary. See the first lines
of extract.dtx for information how to do this. Example files can
be produced by running the file extract.dtx with LaTeX once.

ex­tract – Ex­tract parts of a doc­u­ment and write to an­other doc­u­ment

The pack­age pro­vides the means to ex­tract spe­cific con­tent from a source doc­u­ment and write that to a tar­get doc­u­ment. One could, for in­stance, use this to ex­tract all ex­er­cises from lec­ture notes and gen­er­ate an ex­er­cises book on the fly.

The pack­age also pro­vides an en­vi­ron­ment which writes its body en­tirely to the tar­get file. Another en­vi­ron­ment will write to the tar­get file, but will also ex­e­cute the body. This al­lows to share code (for in­stance, a pream­ble) be­tween the source doc­u­ment and the tar­get file.

Fi­nally, the pack­age pro­vides an in­ter­face to con­di­tion­ally ex­tract con­tent. With a sin­gle pack­age op­tion, one can spec­ify ex­actly which com­mands (counted from the start of the doc­u­ment) should be ex­tracted and which not. This might be use­ful for ex­tract­ing spe­cific slides from a pre­sen­ta­tion and use them in a new file.
