如何创建和打开 ".gmail.txt" 档案

正如你所知，GMail阻止发送和接收带有压缩附件的电子邮件，这些附件包含触发其“恶意代码”过滤器的某些源代码。因此，Gambas IDE中有一种方法可以将源包压缩和解压缩为文本（.txt）格式。

When we want to create a package like this so as to get past GMail's filters, we create the package as usual Project > Create > Source Package... Except before we click on the OK button, we will have the foresight to check Transform into a ".gmail.txt" archive that fools GMail. After creating the archive in this manner, we can attach the file with confidence knowing that our email should get delivered.

But then how do we open such a transformed file in the IDE?

We simply use the Select a Project > Open tab window that we get from the menu or the Open Project button (File > Open Project...). Both normally archived files and these special text files appear on the left side of the window. To open the ".gmail.txt" file, just right-click on it and choose Uncompress the file. This operation must be repeated twice: the first turns the text archive into a normal compressed file, the second unzips it so it can be opened in the IDE.

Let's take a practical example with this archived email with an attached special text archive:
https://lists.gambas-basic.org/pipermail/user/2022-January/075136.html

The archive is enclosed within <salt > and </salt> tags. It is necessary to select it all including the tags, copy & paste it into a text editor, and save it with any basename you wish, without spaces, but with an extension of ".tar.gz.gmail.txt". If you do not give it that exact extension, Gambas will not recognize it as a special ".gmail.txt" archive.

Then you can navigate to this file within the IDE and unpack it (twice) as usual.

Working with ".gmail.txt" files with an older version of Gambas

If you do not have a recent version of Gambas, the IDE will not be able to do what is said above. In that case, to unpack the file, use the following shell command on the command line: Note: Quotations marks around the filename are required if it contains spaces.

There is a utility on the Gambas Software Farm that allows you to both pack and unpack these types of compressed files. Just do a search on the Farm for "gmail-attachment-pipe".
