A short example implementation
status 2007-05-13
current status:
- tlsrc -> tlp conversion
Implemented:
. auto generation of packages in texmf-dist according to their
directory name
. package version based on the maximum of all package file
last changed revision number of subversion
Missing:
. update/inclusion of information from the catalogue
. missing source keys?
. ???
I have generated tlsrc files for all texmf-dist/tpm/*.tpm files containing
only the name, executes, and depends, and from these I generated tlp files
The automatic procedure works quiet well:
tlsrc files with manual patterns: 16
buggy packages: 22
Buggy packages are packages where the files currently in the tpm and
those in the generated tlp differ. (one package is probably a false error:
arabxetex)
The list of tlsrc files which had to be adjusted is (not surpising):
bibtex, context, dvips, fontinst, groff, lambda, latex, makeindex,
metafont, metapost, mex, mft, omega, plain, tex4ht, xetex
Generation time on my small laptop for all texmf-dist tlp is around 40sec
- tlp -> tldb conversion
Implemented:
. just do it, trivial, cat $i, echo "" ...
Missing:
. no idea what it shoud do
- usage of tldb
Implemented:
. reading of the whole tldp and generation of a perl hash
. generation of tlp files from the tldp database
Missing
. replacement/update/other operations on single tlp entries
this should be trivial as it is only hash operations
make runs the following commands:
1) generates tlp from tlsrc/*.tlsrc
currently implemented is the auto generation of packages
if no pattern is given (see tlsrc/foo.tlsrc) and more
complicated patterns (using perl regexp atm).
2) generates a tldb from tlp/*.tlp
trivial concatenation with empty lines between
3) moves tlp to tlp.old
4) re-generates the tlp from the tldb
use_tldb defines a function read_tldb_file which reads the whole
file into a hash
5) compares tlp.old and tlp
