Install Mail Hog

Install the Go programming language

cd ~
sudo apt-get install golang-go
mkdir gocode
echo "export GOPATH=$HOME/gocode" >> ~/.profile
source ~/.profile

Download and configure MailHog

go get github.com/mailhog/MailHog
go get github.com/mailhog/mhsendmail
sudo cp ~/gocode/bin/MailHog /usr/local/bin/mailhog
sudo cp ~/gocode/bin/mhsendmail /usr/local/bin/mhsendmail

Let’s connect PHP with MailHog at php.ini. Find the sendmail_path setting and set it in the following way:

sendmail_path = /usr/local/bin/mhsendmail

The php.ini for both CLI and Apache should be configured. It can be found in the folder /etc/php/7.4/apache2 and /etc/php/7.4/cli. The location may change based on the distro.

Start MailHog when the system boots

1. Create the file /etc/systemd/system/mailhog.service.

sudo vim /etc/systemd/system/mailhog.service

2. Paste the following into it:

[Unit]
Description=MailHog service

[Service]
ExecStart=/usr/local/bin/mailhog \
  -api-bind-addr 127.0.0.1:8025 \
  -ui-bind-addr 127.0.0.1:8025 \
  -smtp-bind-addr 127.0.0.1:1025

[Install]
WantedBy=multi-user.target

3. Start the service : sudo systemctl start mailhog. Verify it is working by accessing the URL – http://127.0.0.1:8025
4. Enable the service so it runs on bootup sudo systemctl enable mailhog
5. Restart your system
6. After restarting, mail hog can be accessed in the URL – http://127.0.0.1:8025

If you ever encounter ugly Tamil fonts in Elementary OS or other Ubuntu based distros, the following method will help in fixing it.

Create a file called 90-tamil.conf in the folder ~/.config/fontconfig/conf.d. If the folder doesnt exists, create it.

In the file add the following code and save the file. The following code uses Noto Serif Tamil as Serif font and Noto Sans Tamil as sans font. Change the tamil font as your liking.

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
    <match target="pattern">
        <test name="lang" compare="contains">
            <string>ta</string>
        </test>
        <test qual="any" name="family">
            <string>sans-serif</string>
        </test>
        <edit name="family" mode="prepend" binding="strong">
            <string>Noto Sans Tamil</string>
        </edit>
    </match>
    <match target="pattern">
        <test name="lang" compare="contains">
            <string>ta</string>
        </test>
        <test qual="any" name="family">
            <string>serif</string>
        </test>
        <edit name="family" mode="prepend" binding="strong">
            <string>Noto Serif Tamil</string>
        </edit>
    </match>
</fontconfig>

After adding it, run the following in Terminal to see the system is picking the font properly.

LANG=ta_IN fc-match

For, me its shows some thing like this:

After adding these, the fonts in the entire OS should look like this(not only in the browser).

After seeing one of my friend Shrini using ORG mode in Emacs, I have been tempted to try it. I have heard of ORG mode before, but not get any inspiration to use it. Shrini, gave me a short intro to ORG mode, while we were pair programming for an opensource project. So, I decided to give it a try.

I always get night mare, while thinking of emacs. My previous experience with emacs was not good. So, I decided to try it with Spacemacs. Everytime I try a new IDE or Editor, my usual habit is to check the Tamil language support in it. The Tamil unicode font rendering with emacs is broken. But it can be easily fixed, by specifying the font in the dotfile of spacemacs.

(set-fontset-font "fontset-default" 'tamil "Noto Sans Tamil")

After closing and opening the emacs, tamil fonts seems to rendered properly.

Next I tried to type in Tamil using Ibus. I can’t get it working. After some research, I found that the python-ibus and ibus-el libraries needs to be installed. I scratched my head as the usual apt get thing failed. I had to manually download the files and install. (Download Links are provided at the end of the post). Then I need to add the lines in the Spacemacs dotfile.

(require 'ibus)
(add-hook 'after-init-hook 'ibus-mode-on)

After restarting the Ibus Daemon, it seems to be working ok. I am not getting a predictive behaviour with tamil input over spacemacs. Also I feel it is little heavier.

Meet Doom – EMacs

After little searching the internet, I found there is a another emacs distribution called Doom. I just backed up the ~/.emacs.d folder and start playing around with Doom. Doom Emacs has a very light learning curve, for some one familiar with Vim. For tamil font rendering, the unicode package needs to be enabled in the init.el. After making the changes I have to run the sync command for doom ~/.emacs.d/bin/doom sync. Tamil font then seems to be rendered fine in Doom.

As I had already installed the python-ibus ans ibus-el libraries, the tamil input seems to be working fine in Doom. I am using elementary os, it feels so good after setting up the tamil input.
