How can I create a custom date in "snippets" in the Geany text editor?

I often use the Geany text editor to write programming code. I recently knew that we can insert a code snippet in Geany automatically using some keybindings and I liked the idea of that.

So, I went through some of the basics of the snippets in the Geany manual.

And I tried to do this: A required snippet for an Octave script is: 

#!/usr/bin/octave -qf
% Author   : Bhishan Poudel
% Date     :

I_like_this_to_be_inserted_automatically

My attempt so far:

We have to edit the configuration file called "snippets.conf" which can be accessed like this:

Menu Tools → Configuration Files → snippets.conf

Or ~/.config/geany/snippets.conf.

Then, I first checked the file type for Octave scripts:

geany --ft-names

I see the filetype is [Matlab/Octave]. So, I added the following code there. 

[Matlab/Octave]
pre=#!/usr/bin/octave -qf \n% Author    : Bhishan Poudel \n% Date      : {date}\n\n

Note: to find the shebang path for octave installation directory, type which octave

Then to implement the code I created a file called a.m and opened it in Geany. Then the command to try this snippet is *preTab (type pre followed by Tab) then the output is: 

#!/usr/bin/octave -qf
% Author    : Bhishan Poudel
% Date      : 2016-05-23

How can we change the date format to May 23, 2016?

Solution

  • One way to do it is to use {command: date} with date's default command line syntax. So in your case I think it would be

    {command:date +"%b %d, %Y"}

    Which results here into:

    $ LANG=C date +"%b %d, %Y"
May 24, 2016

    Another more general way would be to set up a template for your Octave scripts. Inside your template you should be able to insert values based on Geany's configuration. Have a look into the manual, but something like this saved as a template could work (untested):

    #!/usr/bin/octave -qf
% Author    : {developer} <{mail}>
% Date      : {date}

    But you would need to configure date-format in Geany's preferences — where you can use the options from above.
