Creating language support
This is very easy. Use the portable version to test it.
1-)Go to the languages\ folder and copy the en.ini to <your_country_code>.ini
2-)The file encoding is UTF-8. Edit <your_country_code>.ini, changing just the values part to your language's text.
3-)Make sure to keep %s, %d, %f from values part because they will be expanded in printf()/Format() functions. Like "Do you wish to save %s". The %s will be expanded to the file name.
4-)Start the editor. Choose from menu Configurations->Languages and choose your language.
Creating your own New->Template project
Also, use the portable version to test it.
1-)Go to the templates\ folder and create your template name's folder into it.
2-)Change the whitespaces of the name to "_", the editor will recognize it as whitespace.
2.1-)Because of the Linux .RPM format I had to change all whitespaces in the file names to _. But the edit will recognize as whitespaces, in any platform.
3-)Create a icon.png file inside the folder you created. It will be the icon.
4-)Create a files\ folder inside the folder you created. It will be the files/directories tree of your template.
