Re: pkg to db

Works fine.
To apply is getting interesting but I need a small help. How to add the name of package before description (in DB, not desc file). Below codes display desc only. The /tmp/pkg.tmp is list of all packages in DB.

sqlite3 /etc/pacmenu/pacmenu.db "SELECT name FROM pkgs" > /tmp/pkg.tmp

cat /tmp/pkg.tmp | while read LINE; do
sed -n "/%DESC%/,$ { /%DESC%/ d; /^$/ Q; p }" /var/lib/pacman/*/$LINE*/desc
done

Result will be inserted in table "desc":
name (primary key same as in table "pkgs")
description

EDIT:
Where do I find the packages' group name?

Re: pkg to db

some packages have a %GROUPS% field in their desc file, have a look at the xfce4 tools for example
in /var/lib/pacman/extra/xfce4-mixer-4.2.1-1/desc theres a field

%GROUPS%
xfce4

Do you mean something like:

cat /tmp/pkg.tmp | while read LINE; do
    desc=`sed -n "/%DESC%/,$ { /%DESC%/ d; /^$/ Q; p }" /var/lib/pacman/*/$LINE*/desc`
    sqlite3 "INSERT $LINE, $desc INTO some table"
done

Whatever the sqlite insert syntax is.  You might be better off writing a conversion script in Python or Perl.
Can a package be in multiple groups?

Re: pkg to db

Thanks for the hint. Got it to work.

sqlite3 /etc/pacmenu/pacmenu.db "SELECT name FROM pkgs" > /tmp/pkg.tmp

cat /tmp/pkg.tmp | while read LINE; do
desc=`sed -n "/%DESC%/,$ { /%DESC%/ d; /^$/ Q; p }" /var/lib/pacman/*/$LINE*/desc`
sqlite3 /etc/pacmenu/pacmenu.db "INSERT INTO desc (name,description) VALUES ('$LINE', '$desc');"
done

Re: pkg to db

I want to simplify the description search. Grep can search an assigned number of lines above and under matched pattern.

# grep -1 "%DESC%" /var/lib/pacman/current/abiword-2.2.4-1/desc
(shows one line above and under)

How to get one line under only without showing the matched pattern (%DESC%)?

Re: pkg to db

hmmm, the only thing I'm not sure of... what happens if the description has embedded newlines - I don't know if it *can* happen, but I know the pacman source reads until it finds a blank line... so I guess it's possible

That's why I wrote the sed script:  it quits (Q) when it sees a blank line thus it can handle a multiline desc.

Re: pkg to db

I am not getting a clean insert of description in DB, so there is an experiment going on with different syntax. The problem seems to be in some of the packages themselves. Moreover, processing the descriptions take too long time (40-45s). I may just make one dump file and will be updated through download.

Re: pkg to db

This is simple and fast:

# Current
ls /var/lib/pacman/current/ >/etc/pacmenu/package.txt
cat /etc/pacmenu/package.txt | sed 's|/| |g' | sed 's|-([^-]*-[^-]*)$| 1|g' >/tmp/desc.tmp

echo -e "${YELLOW}Inserting current descriptions in database....${NORMAL}"

awk '{ print $1 }' /tmp/desc.tmp | while read LINE; do
descp=`sed -n "/%DESC%/,$ { /%DESC%/ d; /^$/ Q; p }" /var/lib/pacman/current/$LINE-*/desc | awk '{print $1, $2, $3, $4, $5, $6}`
sqlite /etc/pacmenu/pacmenu.db "INSERT INTO desc (name,description) VALUES ('$LINE', '$descp');"
done

I reduced the inserted descriptions to 6 columns. Many of the desc are too long when six words will do.

The following errors are not caused by sed synatx but sqlite when inserting the descriptions from /var/lib/pacman/. What may cause or how to hide the error messages?

Re: pkg to db

It appears that some of the package descriptions have apostrophes in them...

Re: pkg to db

this should replace the 's with 's if that is what you want to do...

awk '{ print $1 }' desc.txt | while read LINE; do descp=`sed -n "/%DESC%/,$ { /%DESC%/ d; /^$/ Q; s/'/\\'/; p}" /var/lib/pacman/current/$LINE-*/desc`; 
sqlite /etc/pacmenu/pacmenu.db "INSERT INTO desc (name,description) VALUES ('$LINE', '$descp');"
done

Re: pkg to db

Syntax "s/'/\\'/;" didn't work, but works if " ' " removed "s/'//;".

Now current has no error, but extra still has these:

SQL error: near "documents": syntax error

you can do "s/'//g" to replace all occurances.... that's what you want... though I'd do "s/'/\'/g" so the single quotes remain...
