My favourite text editor BBEdit has just been updated. BBEdit 11.6.3 requires Mac OS X 10.9.5 or later, and is compatible with macOS 10.12 "Sierra". This update contains no new features but includes a number of bug fixes.
BBEdit is my Swiss army knife for opening and editing all sorts of text based file formats, other text editors are available.
BBEdit is my favourite text editor and I’ve been a user since way before Mac OSX. The latest update BBEdit 11.6 brings a number of bug fixes and updates but also introduces a new demo mode. For 30 days the full feature set is available for free after which time BBEdit will remain permanently functional with a revised feature set that includes its powerful text editing capabilities but not its web authoring tools or other exclusive features. These features may be re-enabled at any time with a purchased license.
BBEdit 11.6 requires Mac OS X 10.9.5 or later, and is compatible with OS X 10.11 "El Capitan".
BBEdit can be obtained from the online store.
There is also a listing of markdown editors here
If you regularly have to manually edit files containing data in delimited text format then this application maybe of interest.
DB-Text is a general purpose tool for editing delimited text files. It can automatically recognise the used format analysing the content inside. It can accept data with mixed use of quotas and provides tools to copy in CSV (comma separated),TSV (tab separated) or HTML format of selected rows in the clipboard, with a simple click.
I've added it to the Data Analysis Tools page
BBEdit 11.5 has been released.
BBEdit 11.5 adds a variety of new features, and includes changes to existing features and behaviors as well as fixes for reported issues.
Of particular note are
BBEdit now supports the use of iCloud Drive for sharing application support and setup items. This works similarly to the existing Dropbox support: in your "iCloud Drive" folder, create a folder named "Application Support", and then within that create a folder named "BBEdit". You can populate that folder with the contents of your /Users/USERNAME/Library/Application Support/BBEdit/ folder.
BBEdit now supports the use of iCloud Drive for a shared backup folder: in your "iCloud Drive" folder, create a folder named "BBEdit Backups", and if you have turned on Use Historical Backups, BBEdit will use this folder.
I use markdown extensively on my websites, and whilst I mainly use BBEdit I do keep an eye out for new Markdown editors to add to this listing. I was recently alerted to Texts is a cross platform editor that uses plain text Markdown as file storage format. Documents can be published to PDF, HTML, DOCX, EPUB, and other formats from single source.
I use markdown extensively on my websites, “Markdown” is two things: (1) a plain text formatting syntax; and (2) a software tool, written in Perl, that converts the plain text formatting to HTML allowing you to build HTML documents in an easily readable form. As the use of Markdown has increased in popularity there are now a wide choice of plain text/Markdown editors available for MacOSX and recently iOS so I’ve updated the listing of Markdown Editors.
