TextMate

Making multiple changes at once, swapping pieces of code, and a lot more is made trivial with TextMate’s easy way to add multiple insertion points.

See what files have changes in the file browser view, what lines have changes in the editor view, bring up a diff of the current file’s changes, commit a subset, TextMate supports it all for all the major version control systems.

One file mixing languages? Projects using different build systems? Third party code with different formatting preferences? TextMate can handle it all by associating detailed scope selectors with key shortcuts, settings, etc.

Commonly used pieces of text or code can be turned into snippets with placeholders, transformations, and more, to have them adapt according to the context in which they are used.

TextMate uses bundles for customization and supports a countless number of different languages, markup systems, workflows, and more.

Repetitive work can be eliminated with macros. Either save them for repeated use or record a scratch macro for immediate replay.
