[GRASS5] [bug #2733] (grass) note v.convert in UPGRADING

-------------------------------------------------------------------------

doc/vector/vector.html should say how to convert one's old vector file
to new vector files, and visa versa.

Indeed I was sure your vector commands were broken until one day I
used (Debian bullhorn.org) g.list and noticed "oldvect"!

There is no way returning users will know you changed the vector
format unless you tell the whole story in some UPGRADING file, like
spamassassin has.

Anyway, how do I convert my old 5.0 vector files to new ones?
Or maybe one just copies them over or something.

Wait, deep down in the 2002 Blazek conference paper do I finally
notice v.convert. Just wanted to let you know the story.

P.S., $ v.convert help
     Description: Converts between GRASS vector versions.
Say which versions. Indeed prepare for future versions...
Say how to convert backwards too.

P.S., mention all the new restrictions on vector file names there too!
Also mention how to convert most or all of ones files in one step, not
just one at a time. Especially as the names will probably need removal
of now illegal chars.

Maybe you want to get CVS access and fix that. I have more important
things on my TODO with higher priority.

This is a document dedicated to GRASS programming, not GRASS usage.

Please write it for us.

http://grass.itc.it/grass57/manuals/html57_user/v.convert.html

I have added recenctly a new script:

v.convert.all [-r]

which does the job for all maps in the current mapset
(feel free to improve this script).

We cannot mention the zillion GRASS versions by name.

>Say how to convert backwards too.

Suggestion:
Read the manual *completely*, not just the first two lines:
"v.convert converts GRASS 5.0/5.3/5.4 vectors into 5.7 vectors."
"If you need to convert back from 5.7 into the 5.0/5.3 vector format ..."

>P.S., mention all the new restrictions on vector file names there too!

Done. The new man page of v.convert.all explains that this script
automatically changes dots to underlines (can be extended).

>Also mention how to convert most or all of ones files in one step, not

Done in CVS.

Markus

PS: Consider to send text pieces which we can insert by copy-paste.

P.S., $ v.convert help
     Description: Converts between GRASS vector versions.
Say which versions. Indeed prepare for future versions...

Already done, this was changed to:

"Description:
Imports older versions of GRASS vectors."

in CVS some time ago.

Say how to convert backwards too.

already in help page ('v.out.ascii -o') and in G57 tutorial.
