MarsEdit 4 Public Beta

June 28th, 2017

It’s been over 7 years since MarsEdit 3 was released. Typically I would like to maintain a schedule of releasing major upgrades every two to three years. This time, a variety of unexpected challenges led to a longer and longer delay.

The good news? MarsEdit 4 is finally shaping up. I plan to release the update later this year.

Beta Release Overview

Because the update contains many new features that my patient users have been waiting to get their hands on, I want to give folks the option of trying it out early. I think the beta release is very stable, but you’ll have to forgive a few rough edges while I finish things up. If you want to give it a spin, click this link:

Download the MarsEdit 4 Public Beta

The beta release supports Mac OS X 10.10 or greater, though final system requirements are not yet set in stone. Users who own an existing license to MarsEdit 3 can run the MarsEdit 4 beta for free until the final version is released. Customers who purchase a new MarsEdit 3 license from the Red Sweater Store between now and the final release will be entitled to a free upgrade to MarsEdit 4. Unfortunately, the Mac App Store does not accommodate free or discounted upgrades.

If you decide to install the beta, please join us in the Red Sweater Slack team to discuss the upcoming release. As always, I welcome bug reports and other feedback via email as well.

Beta Release Details

So, what’s new in MarsEdit 4? I will write in more detail when the final release is done, but here’s a high level list of some of the things that have been added in the update so far:

  • Editor Enhancements
    • Visual formatting bar – Select common formatting options with the mouse.
    • Typewriter Scrolling – View menu option to keep typing vertically centered.
    • Multimarkdown support – Enhanced functionality when previewing Markdown content.
    • Faster Preview filtering – Code-based Markdown and Convert Line Breaks filters.
    • Interactive image sizing – Rich text mode supports direct manipulation of image display size.
    • Improved “Split Post” UI – Splitter now presented inline in post content.
  • WordPress-specific enhancements
    • Faster refresh times.
    • Featured Image support.
    • Post Format support.
    • Per-post Author editing support.
  • Improved system integration. Now supports standard autosave and version history for locally saved drafts.
  • Expanded post downloads. WordPress and Blogspot blogs can now be configured to download the entire history of posts instead of a recent subset.
  • Automated preview templates. Click the “Download Template…” button from the template editor to automatically detect your blog’s theme.
  • Safari App Extension. Active the “Send to MarsEdit” extension in Safari to easily create new drafts citing the page you are viewing.
  • Application Sandbox. The app is now sandboxed for increased security.

On top of all these, there are numerous smaller changes that you may notice and appreciate. Please let me know if you decide to try the app, what you like, what you don’t like, and I’ll do what I can to continue improving the app both for the 4.0 final release, and beyond!

Blogger’s Obfuscated IDs

April 4th, 2017

For years, MarsEdit was not able to upload directly to Google’s Blogger service. Instead, it had to upload to Google’s sibling service: Picasa Web Albums. Recently, Picasa has been folded into Google Photos, and in the course of the transition, Google has forbidden apps such as MarsEdit from creating albums on the service.

This left MarsEdit in a bind with respect to supporting image uploads for Blogger. The good news is Google added support for uploading directly to the Google Photos album that is used for Blogger images. Sort of…

MarsEdit 3.7.11 introduced the ability to upload directly to the Blogger photos album, and it seems to work flawlessly for many Blogger users. Unfortunately, it fails spectacularly for a subset of users. Specifically, if your Blogger user profile is set to use a “Blogger-specific” identity, you will not be able to upload images from MarsEdit. If, on the other hand, your Blogger profile is set to use a Google+ identity, everything should work fine.

The cause seems rooted in Blogger’s understanding that a “Blogger-specific” profile may be used for purely pseudonymous blogs. For this reason the information they share with MarsEdit includes a user ID that is not the user’s actual ID, but an “obfuscated ID.” When MarsEdit proceeds to use this ID to upload to Google Photos, the tell-tale error message is generated:

Can’t upload file for [your blog name] because the server reported an error: Invalid length for obfuscated ID "[your obfuscated ID]".

I’m not sure yet whether the obfuscated ID is meant to work, but that there is a bug in the Google Photos API. Ideally, that is the case and the Google Photos team could fix something on the server to get things working. On the other hand, it may be intentional that no client such as MarsEdit should be able to use one of these anonymized IDs to upload photos to Google.

The long and short of it is if you want to reliably upload photos from MarsEdit to a Blogger blog, you need to switch your blogging identity to a Google+ account. Google has documentation about this process, which also includes caveats about the implications of making the switch:

Change your profile on Blogger.

Existing MarsEdit users who had previously established a workflow of uploading images may already have a “MarsEdit Images” album among your Google Photos Albums. If so, you can achieve a short-term workaround by downgrading to MarsEdit 3.7.10, which will continue to try uploading to an existing MarsEdit Images album. Unfortunately, when this album reaches capacity, MarsEdit will not be able to create a new album.

I will continue tracking this issue while I weigh my options for additional workarounds. I am also in touch with some folks at Google and I hope they will have advice or devise a reliable means for MarsEdit to support image uploads regardless of the “identity” setting on a user’s Blogger account.

Diamond Anniversary

March 31st, 2017

Only after reflecting on the ten-years-old support for Blogger in MarsEdit, did I realize I had missed yet another important milestone in Red Sweater history:

February 22 marked the ten year anniversary of my acquisition of MarsEdit:

You read that right, no need to run for another cup of coffee. MarsEdit, the kick-ass, intuitive web-publishing powerhouse which I’ve been using to write entries here since I started blogging almost two years ago, is now part of the Red Sweater family of products. What an exciting day!

Where has the time gone? I sometimes despair at the relatively slow progress I seem to make in the development of all my software, MarsEdit included. On the other hand, looking back at the screenshot I included in that original post, it’s also easy to appreciate how much the app has evolved in the years since I’ve been developing it:


Wow. Well, first of all I’m writing this post on a Retina display, and I certainly hoping you are reading it on one. The first thing that jumps out is how fuzzy everything used to be. How did we live that way? Furthermore a number of key UI elements have been dramatically reworked just in the post editor interface alone. Let’s see how things look on the version of MarsEdit I’m running:

Diamond Anniversary

Now, to be fair, this is a screenshot from an as-yet unreleased version of MarsEdit, but the gist of the design is pretty close to the shipping MarsEdit 3.7.11. The main difference experienced MarsEdit users will notice is the addition of an icon formatting bar above the main text content. This little teaser is your reward for having read through the length of this post, and for helping me in celebrating my Diamond Anniversary with MarsEdit.

MarsEdit 3.7.11: Fix Blogger Photo Uploads

March 31st, 2017

MarsEdit 3.7.11 is now available from the MarsEdit home page, and will be submitted to Apple for update on the Mac App Store.

For years, Blogger didn’t support direct photo uploads to a blog. Instead, MarsEdit uploaded photos to a photo album on Google’s Picasa Web Albums service. This was a reasonable workaround, since the same credentials used to log in to the blog could also be used to upload photos.

A few weeks ago, Google changed the behavior of the Picasa Web Albums interface that MarsEdit connects to, making it impossible to create a new album for MarsEdit photos. This means that existing MarsEdit users who had not met the quota limit for their album could continue uploading photos, but new MarsEdit users and existing users who met the quota, could not create a new album to continue uploading.

Luckily, in the years since I first added Blogger support to MarsEdit (ten years ago!), Blogger eventually added support for uploading directly to the blog-specific photo album.

MarsEdit 3.7.11 takes advantage of that access, and all photos uploaded through MarsEdit to a Blogger-hosted blog, will from this release forward be added directly to the same album as photos uploaded through the Blogger web interface.

As a special note for those who would prefer to have their photos uploaded to another Google photo album, if you locate the Google Photos album ID, you can use this long numeric value as the “Section” in MarsEdit’s photo upload details view, to upload directly to whatever album you choose (providing your Google account has permission to do so).

This update also includes a minor bug fix for users of the Japanese service.
