Are there any ways to selectively tangle blocks?
By that I mean suppose there are a dozen src blocks in a file, but I want
to selectively tangle only a few of them, selecting them by a tag, for
example, or some other property. These might have mixed languages, e.g. a
config files, a python script, and a makefile.
The use case here is I have an org document that I use to document a
simulation. The simulation has several config files, and a makefile, and
there is a python script that does analysis. I like to put all of these in
src blocks and then use a sh block to run the actual simulation command. I
usually put a :var a=(org-babel-tangle) header in the sh block, which makes
sure the files are tangled, and then runs the shell commands. But this
tangles all the files in the buffer, which is usually not what I want
(there are sometimes multiple simulations described in one file). The
blocks are not always in one subtree, so it isn't a matter of just
narrowing, and they are mixed languages (text, make, python, etc.) and
target files so I can't just target one file.
The only mechanism for this i have come up with is to use
org-babel-map-src-blocks to run a check on each block to see if it matches
my tangle criteria and then run (org-babel-tangle t) on that block. This
seems to work fine, but I thought I would check if anyone else has a better
solution.
