You came to the correct place, this
document will guide in the process of
deploying a development version of
this project.

## Installing

This guide is centered on Debian 12, if 
you are using a different OS and do
not know how to continue ask us.

### Postgresql notes.

We are going to use the peer authentication that
comes preconfigured in Debian, if you are using
other OS you should care of `pg_hba.conf` to
be configured as peer for empty address.

This is how it looks on the Debian I used.

You can also configure it with password if the database
server is not the same host that the webserver, it
is supported by the software.

```
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            scram-sha-256
# IPv6 local connections:
host    all             all             ::1/128                 scram-sha-256
# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     peer
host    replication     all             127.0.0.1/32            scram-sha-256
host    replication     all             ::1/128                 scram-sha-256
```

### Installing development deps

```shell
sudo apt update && \
sudo apt install git postgresql redis pwgen liblocal-lib-perl libpq-dev nodejs npm sassc
```

### Cloning the project and preparing it.

```shell
if ! grep PERL5LIB ~/.profile; then
    perl -Mlocal::lib 2>/dev/null >> ~/.profile ;
fi && \
source ~/.profile && \
rm -fr ~/.cpan && \
( echo y && echo reload cpan && echo o conf commit ) | perl -MCPAN -Mlocal::lib -e shell && \
cd ~ && \
sudo rm -rf LasTres && \
git clone https://git.owlcode.tech/sergiotarxz/LasTres && \
cd LasTres && \
npm install && \
perl Build.PL && \
./Build installdeps && \
cat << EOF > las_tres.yml
secrets:
  - $(pwgen -s 512 1)
database:
  dbname: las_tres 
hypnotoad:
  listen:
    - http://*:3000
EOF
```

### Setup the database

```shell
( cat << EOF
create user $(whoami);
create database "las_tres";
grant all privileges on database "las_tres" to $(whoami);
alter database "las_tres" owner to $(whoami);
EOF
) | sudo -u postgres psql
```

### Deploying the database

```shell
cd ~/LasTres && \
perl script/install.pl
```

## Common development steps.

### Rebuilding the js.

```shell
cd ~/LasTres && \
npx webpack
```

### Rebuilding the css

```shell
cd ~/LasTres && \
bash build_styles.sh
```

### Starting the development server

```shell
cd ~/LasTres && \
perl -Ilib script/las_tres daemon
```

### Create a database update

After updating the Result Classes in this file `lib/LasTres/Schema.pm`
increment `our $VERSION =` plus one, after that execute the following command:

```shell
cd ~/LasTres/
perl -Ilib script/prepare.pl
```

### Apply database updates.

```shell
cd ~/LasTres/ && \
perl -Ilib script/upgrade.pl
```
