how to configure multiple locate dbs

[senior7515]

Hello, 

I can't figure out how to configure helm to look up multiple locate dbs. 

What I would like to have is:

1. project locate.db file 

    a. Ideally it can pick up a 'locate.db' from the root of this vcs directory. Meaning if I open a file on '~/src/project.git' it can pick it up even if i'm in '~/src/project.git/some/other/path' 

2. other locate db (emacs config & other paths) that I have configured on my ~/locate.db

3. system locate.db

I tried given multiple paths to:

(helm-ff-find-locatedb "~/locate.db")

But haven't been able to figure out. 

Any pointers would be greatly appreciated.

I would still like to know the solution to locatedbs path. However, the locate-per-project question can be disregarded. 

I just learned of helm-git and it works really well. 

Thanks again!

C-u C-x c l
if your locate.db exists, start to search, otherwise press RET to create
it.
Same from M-x helm-find-files:
press C-u C-x C-f

Please use helm-ls-git, it is the improved and maintained version of
helm-git.

Hi Thierry,

Thanks for the reply, very insightful.

2 things:

1. I saw that you are one of the members of emacs-helm group. Is there
a chance that you guys can push helm-ls-git to melpa or
mamalade-repo.org. Is really nice on emacs24 to just do
package-install helm-ls-git. (helm-mercurial-* would be nice too)

2. I can fire up helm-find-find and I in fact see that it is using
locate command results. This is great. What I was looking for is a way
to configure helm to look for locate.db files in some other
directories, perhaps part of my init.el script.

The system locate.db updates every 24 hours. However, I have my own
cron job that updates my ~/workspace every 10 minutes eventually I'll
get around to writing something with inotify so that it updates on
file delete/add. I like this because when I switch branches my old
locatedb is essentially useless. This happens quite often.

I tried your suggestion of ' C-u C-x c l ' and it just brings up the
'pattern: ' on the mini-buffer. This indicates that the locate.db
exists as per you comment but I want helm to look for multiple
locate.db files. This is the part i'm a bit confused, how to make this
part of my init script.

one in ~/locate.db && one in the system wherever it exists.

Thanks again.


Sincerely,
Alexander Gallego

You should ask at melpa for this, I am just developing helm, no more.

Probably you are speaking of `helm-for-file', not `helm-find-find'
(which doesn't exists).

You have nothing to configure:
M-x helm-find-files
=> navigate to the directory of your choice (Without quitting helm)
Hit `C-u M-.' RET and start writing in pattern prompt.

Same as above but instead of:
`C-u M-.' do `C-u C-u M-.' and RET
This will rewrite your locate.db file.

Thanks for the help. I submitted a pull request to Melpa for
helm-ls-git and it was merged in. So hopefully I can pull from Melpa
later this afternoon.

Thanks again.

Sent from my phone. Please excuse any typos.
