The "calendrier" folder is copied to the folder "~/conky".
The ".conkyrc" are copied to your Home folder.
It is also necessary to create a file ".reminders" in your Home folder.
"debupdate.sh" only works if the verification updates are done automatically in your system.
Synaptic and Thunderbird must be started with the files tunderbird and sinaptic in the "calendrier" folder.
You can copy these files in "/usr/local/bin".
You must also set in the file "pop3.pl" (except V6) our mailbox with your username and password.
Refresh the date at midnight + 2 seconds.
The start of conky is through the "calendriermailapt.sh" file located in the folder "~/conky/calendrier/launchers."
"calendriermailapt.sh", which you can copy in "usr/local/bin" is a rocker launcher to stop or start viewing three conky (version, calendar and mailapt)
"mail_apt_data_panel" (which I put on my personal system autorun) is a rocker launcher to stop or start "conkyrc_mail_apt_data" (which allows the search for new packages and new mail every 3600 seconds.


Add datas and launchers diagrams images.

V6.9
Access to the site "Acapela" speech synthesis is no longer free so I deleted all voice messages from my utilities.

V6.8
Test if the first line of "ncal -h -b -3" is the current year in the files "calendar.sh and calendar2.sh " (Lines 52 to 59).

V6.7
Still have problems with "ncal". Corrections made in the files "calendar.sh and calendar2.sh".

V6.6
Shift problem in the calendar. Removing the first line of "ncal" over three months in the files "calendar.sh and calendar2.sh" line 22.

V6.5
Adding code name of the GNU/Linux distribution and desktop environment in the "version.sh" file.
I noticed that on some distributions "gawk" is not installed by default.
So if this is the case, install the package not to be errors with the "strftime" function in the files "calendar.sh" and "calendar2.sh".
Font replacement "Droid Sans Mono Bold" to "Corporate Mono Bold Extra" (Problem Droid size with some distributions).
Correcting errors in the file "tunderbird".
Change the color text in the calendar to be more readable.

V6.4
Adding architecture in the "version.sh" file.
Color change in the files "calendar.sh and calendar2.sh".
Added 4 launchers rocker:
"Conky_version_seul" to show or hide Conky Version Only
"Conky_calendrier_seul" to show or hide Conky Calendar Only
"Conky_mailapt_seul" to show or hide Conky MailApt Only
"Suivi_details_mailapt.sh" to display a dialog box detailing the updates and new messages.

V6.3
Script "calendar.sh" changed by Kino - CrunchBang Forums on 03/26/15 to work properly with the latest versions of utilities "remind" and "ncal".

V6.2
Replacing Google speech by Acapela speech.
It is necessary to install:
curl (command line tool for transferring data with URL syntax)
SoX (complete tools for sound processing)
libsox-fmt-mp3 (MP2 and MP3 library for SoX)
You can change "MyLanguages" and "MySelectedVoice" in the files "acapela_command" and "acapela_command_vierge" with the desired language and voice that are listed in the file "acapela.txt".

V6.1
Connection problem with "http://translate.google.com/translate_tts".
Reprogramming line 30 of file "google_speech2.sh".

V6
It is necessary to install three additional packages :
yad (Dialog Box).
ccrypt (file encryption).
libappconfig-perl (appconfig module).
I replaced "pop3.pl" with "pop_mes2.pl" that give more information about the mailbox.
When you first launch "mail_apt_data_panel", you can set automatic startup, a dialog box will open prompting you to enter the parameters of your mailbox and the encryption key for the configuration file "mail.conf" which will then create.
The decryption key will be required to research each new messages.
After the search is completed a new box will ask you to enter twice the encryption key to protect your configuration file "mail.conf".
I also created a "suivi_details_mailapt.sh" launcher (folder calendrier/launchers) you can copy "usr/local/bin" which allows you to view, in a dialog box, the new packages and new messages.
This dialog box contains two buttons that start Synaptic and Thunderbird.

V5.3
I forgot to tell you that it was necessary to install the package "mpg123" for sound.

V5.2
Presence of an annoying space at the beginning of the name of mp3 sound files. Problem solved by adding in the script "google_speech2.sh" line 28.
Delete all the files that the mp3 extension in the folder "~/conky/calendrier/sons"
I added another reader mails bash "Markus Fisch" (which also create a beautiful circular dock "PieDock") and its help file. You can use it instead of "pop3.pl" by uncommenting line 17 in "~/conky/calendrier/mailapt2.sh" file and commenting out the line 16 and do the same thing in the file "~/conky/ calendrier/tunderbird".
You should already have created in your Home folder ".readmailrc" with your email settings (to read the help).

V5.1
Excuse me, I forgot to include in my archive files ".conkyrc".
Adding spoken messages to the rocker launcher opening the mail-apt window conky. (Change in the "debaptupdate2.sh" "pop3.pl" and "calendrier.sh" files).

V5
It is necessary to add a package to get the HomeDir Perl module for "pop3.pl" (libfile-homedir-perl for ubuntu)
Adding spoken messages for "apt-email" .I am largely inspired by the script "Speech Script by Dan Fountain".
Messages are obtained from "http://translate.google.com/translate_tts" and The audio files copied to the progressively in the folder "~/conky/calendar/sons."
Improved pop3.pl script (problem with backquote in particular and replacing the command "echo").
Some additions to the "debaptupdate2.sh" scripts and "pop3.pl" to connect to the script speech "google_speech2.sh".

V4.1
Fixed an error in "~/conky/calendrier/.conkyrc_chargement2" file about the "fond355x25.png" picture.
Creating a launcher switch "mail_apt_data_panel" to stop or start "mail_apt_data". You can copy to "/usr/local/bin/".

V4
Addition 3rd panel with Ubuntu version, Kernel, RAM, Swap, CPU load, Process.
Change line 5 "cat /etc/lsb-release" file "~/conky/calendrier/version.sh" if necessary, for another Linux distribution.

V3
The package "aptitude" is no longer needed, you can uninstall it. Looking for updates is via "apt-get"
Create a file "~/conky/calendar/launchers/mailapt_data" which tracks the number of updates to packages in all deposits and new mails from your ISP. You can copy it to "/usr/local/bin" and start with automatic loading "XFCE" (equal opportunity for other distributions).
Not to be obliged to enter a password, it is necessary to add the following two lines in the file "/etc/sudoers"
foo ALL = (root) NOPASSW /usr/bin/apt-get - simulate upgrade
foo ALL = (root) NOPASSW /usr/bin/apt-get update
Replace "foo" with your "username".
Also change the launcher switches "~/conky/calendar/launchers/calendriermailapt.sh" (1 click opens the conky, click closes another one), you can also copy "/usr/local/bin".
Remove ". Conkyrc_mail_text,. Conkyrc_mail_text2,. Conkyrc_apt_text,. Conkyrc_apt_text2, and apt_refresh.sh mail_refresh.sh"
Renaming "debupdate.sh" with "debaptupdate.sh"
Create a file "~/conky/calendrier/debaptupdate2.sh" which indicates the number of updates without asking the deposits after closing "Synaptic".
Changing names for launchers "synaptic and thunderbird", now they call themselves "sinaptic" and "tunderbird"
Change configurations "and sinaptic tunderbird."
Adding trace file "~/conky/calendrier/suivi" of data updates.
Test network connection in "~/conky/calendrier/mailapt.sh".
Create a file "~/conky/calendrier/launchers/meteo_mail_apt_data ( weather + mail + apt datas )".You can copy it to "/usr/local/bin" and start with automatic loading "XFCE" (equal opportunity for other distributions).

V2.1
Update at midnight does not seem to work, so I replaced "execp" with "exec" to start "calendrier_refresh.sh" in files ".conkyrc_calendrier_text" and ".conkyrc_calendrier_text2". Refresh the date at midnight + 2 seconds.
The "conky_mailapt" is now divided into 3 conky (background, mail and apt) for more fluidity when refreshing.
I created one switch launcher in a panel pointing to "calendriermailapt.sh" (1 click opens the conky, 1 another click closes)

V2
Change in appearance and improved parameters in conky.
Refocusing of calendar displaying the background image in a different conky because "calendar.sh" appears, too far left.
The start is the file "calendrier.sh" in the "calendrier" folder
