Is that already + available somewhere? + tschwinge: Yes, you can get it in its current state at + git://svcs.cs.pdx.edu/git/moin2iki.git + tschwinge: That repo has scripts for converting from Moin + and TWiki to ikiwiki. + tschwinge: Work in progress. + tschwinge: For a purely TWiki setup, it should work fine. + tschwinge: You need a number of depenencies, though, and we + haven't documented them well yet. + JoshTriplett: Thanks, I'll have a look and report back (in some + days, I hope). + tschwinge: In particular, you need HTML::WikiConverter with + our 12 ikiwiki-related patches. + tschwinge: + http://rt.cpan.org/Public/Bug/Display.html?id=24446 + +As I had difficulties with extracting the patches from the cpan site, they were +also made available by the authors at +. + +The Debian package *libhtml-wikiconverter-perl* is too old at least until +[[debbug 419918]] is closed. + +For converting from rcs files (as used by TWiki) to a git repository you'll +need to get `git clone git://people.freedesktop.org/~keithp/parsecvs` and build +it. Or don't do that and install the Debian *git-cvs* package instead; see +below. + +Here is the command line I used (line breaks added for readability) to create +an *Authors* file from the TWiki files, suitable for *parsecvs* or +*git-cvsimport* to use: + + $ sort < data/Main/TWikiUsers.txt | uniq | ↩ + while read s n r; do ↩ + ( [ "$s" != \* ] || expr "$r" : .\*\< > /dev/null) && continue; ↩ + echo "$n"="$(recode Latin1..UTF-8 < data/Main/"$n".txt | ↩ + awk -v name="$n" 'BEGIN { FS = ": "; email = "web-hurd@gnu.org" } ↩ + { sub("\r$", "") } $1 ~ /\* Name$/ { name = $2 } ↩ + $1 ~ /\* Email$/ { email = $2 } ↩ + END { print name " <" email ">" }')"; ↩ + done | tee Authors + +The old TWiki installation had managed to corrupt one of its own rcs files, +which both *parsecvs* and *git-cvsimport* stumbled on. As that file was not +essential for me, I simply deleted it. + +The final output (after the TWiki markup to Markdown markup conversion) was +expected to pour out *.mdwn* files. However the original TWiki files are named +*.txt*. As the *git-map* step as yet (would this be possible at all?) has no +way to rename the files while converting, I simply adapted the input files' +names to what was expected: I ran a the following command to rename the +*.txt,v* files to *.mdwn,v* files before running *git-cvsimport*: + + $ find ./ | grep \\.txt,v | while read f; do ↩ + mv -vi "$f" "$(expr "$f" : \\\(.\*\\\)\\.txt,v)".mdwn,v; done + +Instead of using *parsecvs* (which finally even choked on the valid rcs input +files) I eventually ended up successfully converting the old TWiki with +*git-cvsimport*: + + $ git-cvsimport -v -d "`pwd`"/../hurd-wiki/ -z 0 -a -A ../Authors data + [...] + Committed patch 4698 (origin +0000 2007-04-13 17:40:08) + Commit ID c33d05d0274d0d602fba835805abb9ba413c65c6 + Generating pack... + Done counting 18576 objects. + Deltifying 18576 objects... + 100% (18576/18576) done + Writing 18576 objects... + 100% (18576/18576) done + Total 18576 (delta 12567), reused 16106 (delta 10886) + Pack pack-d38e3d55705f5d355f669aaa7d993420b50798d0 created. + Removing unused objects 100%... + Done. + DONE; creating master branch + +The only thing I had to do to make the conglomerate of rcs files a *valid* cvs +repository (read: to satisfy *git-cvsimport*'s needs) was a `mkdir +../hurd-wiki/CVSROOT`. + +Then let's convert the whole git tree from TWiki syntax to Markdown: + + $ TWIKI="`pwd`"/../hurd-wiki tw_2001-12-01_2iki "`pwd`"/.git + [...] + +After that I repeated -- in a separate directory!, they can be merged later -- +the same last steps again, replacing *data* with *pub*, which contains the data +files that had been attached to the wiki pages (like images, for example). -- cgit v1.2.3
