Today, I implement plaintext message viewing and hook it up to the message list.
I also review a cleanup of int variables to make them either short or long
throughout the project.
I wrote a utility function to parse RFC822 dates/times sent by the IMAP server, which then converts them to a UTC time. In this video, I hook it into the IMAP parser and add a resource string for the local timezone offset setting, so these UTC times can then be converted to a local time and displayed in the message list.
I recently read about using a jump instruction as an LDEF resource to allow
keeping the list definition function in the main program executable/project, so
in this video I implement the technique for the message list.
In this video, I get the list of messages displaying again and fix a bug that
occurred when closing a mailbox.
I provide a quick summary of creating LDEF procedures in THINK C for drawing
custom list cells, which I will expand upon on in a future video.
In this episode, I fix the off-by-one error in the IMAP envelope parser noted
in the previous episode, then improve the tracking of a malloced buffer that
gets shifted around during parsing.
Returning to the development of my IMAP client, in this video I add
functionality to fetch the default mailbox name from the resource file (later to
be moved to a preferences window) and then eventually locate a crash in the IMAP
protocol parser from a bogus memmove.
In this video, I create a new GUI application from scratch, create a resource file and add an image to it, and then display that image in a window. I also cover using THINK C's debugger to inspect a struct. Then, my Mac dies.
I've been writing an IMAP client for and on my Mac 512Ke over the past many weeks. Taking inspiration from Andreas Kling's excellent YouTube videos documenting his development of the Serenity operating system, I thought I'd start screencasting some of my work.
This video is the first of hopefully many and presents a quick introduction to System 6, HFS resource forks, THINK C 5.0, and a look at some of the progress of my IMAP client so far.
