how to configure Git to treat certain type of ascii files as binary files

how to configure Git to treat certain type of ascii files as binary files

[Weiwei Shu]

Hello everyone,

My first post in this mailing list. Could some one direct me to some
document/manual pages to setup Git to treat ascii files as binary
files? I'm using Git to do circuit schematics (SPICE files)
versioning. I will not do any merging or editing stuff with external
editors. The only way to change it is to use schematic capture GUIs
(Cadence, ADS, etc). So I'd like to treat them as binary files to
reduce the possibilities of messing them up.

I know it seems a little bit stupid to use Git to do such an easy job.
But hey, it's the most eye-catching SCM software, isn't it?

unless you enable cr/lf handling git won't change ascii files.

what is it that you think needs to be done differently for these files 
than for any other files?

Git doesn't futz with your file contents unless you explicitly ask it
to, such as the CRLF-munging stuff. By default, all files are
"binary".

Thanks David.

Well, for binary files, SCM tools (like subversion) usually work as
"lock-modify-unlock" mode in which merging is not supported since the
files are not human-readable. The schematics are ascii files, but I do
not want them to be merged if I run "merge" command. Instead I'd like
Git ask me to "look-and-replace". I know Git is not meant to do this
kind of jobs. Just curious if it is able to be configured to work in
that way.

First, git does not modify files unless you have core.crlf set,
and even then it warns about irreversible transformations
(core.safecrlf)

Second, using gitattributes you can set diff driver and merge driver;
one of possibilities is to treat file as binary (binary diff and no
using 3-way file merge).

Thanks Jakub. I'll read its manual and try to play with it. Thank all
for replies!
