VEDIT
Encyclopedia
Vedit is a commercial text editor
for Microsoft Windows and MS-DOS from Greenview Data, Inc.
Vedit was one of the pioneers in visual editing
. Today, it is a powerful and feature-rich general-purpose text editor.
Vedit can edit any file, including binary files and huge multi-gigabyte files. Still it is compact and extremely fast,
perhaps because it is written mostly in Assembly language.
. The exe file size is only 158k.
The Windows version was written mostly in Assembly, but the user interface has been written in C.
The size of exe file is 573k, and no DLLs are used.
Vedit uses its own file buffering which is faster than the virtual memory of Windows.
In addition, it uses very little of Windows' resources.
When editing large files, only part of the file is loaded in the memory at a time and temporary files are created only as needed.
Thus, even multi-gigabyte files are opened in a fraction of a second.
Therefore Vedit loads very fast and executes all operations fast.
And since it does not hog Windows resources, it does not slow down the other applications either.

- When the IBM-PC was introduced, Vedit was one of the first applications available for it in 1982. Versions of Vedit were available for MS-DOSMS-DOSMS-DOS is an operating system for x86-based personal computers.

. On QNX, Vedit was supplied as standard editor.
- Vedit was sold in three versions: Vedit Jr, Vedit and Vedit Plus. Later, the first two were dropped and Vedit Plus was renamed to just Vedit.
- CompuView was shut down year 1989, but a new company, Greenview Data, continued the development of Vedit starting from 1990.
- The first Windows version (Vedit Plus 5.0) was published in 1997.
- 32-bit Windows version (v5.1) was published in 1998.
- 64-bit Vedit Pro64 was published in 2003. It uses 64-bit addresses and data handling to support files larger than 2GB, but does not require a 64-bit processor or 64-bit OS.
- Development and marketing of Unix, QNX etc. versions were gradually stopped. DOS-version has still been developed in parallel with Windows version and both have the same functions (as much as possible). DOS version is no longer sold separately or supported, but it is still packaged with the Windows versions.
- On February 2008, Greenview Data announced that the old CP/M and CP/M-86 versions of Vedit can be freely shared.
- With version 6.20.1 (May 2011) the old Windows Help system was replaced with HTML Help system in order to support Windows 7 and Vista.

or any mixture of them. A special feature in Vedit is that a document window can be 'full size'. The size of such window is adjusted automatically (as with maximized windows), but overlapping windows can be used at the same time.
- Vedit has project support. Opening a project automatically loads all the files, file list, settings and session details. You can instantly switch from one project to another by double-clicking on the project name in the sidebar.

s and its own pattern matching codes (which are faster and easier to use).
- Wildfile function allows you to perform searches, search/replace operations, filtering, run commands or even run complex macros on large set of files on disk recursively.
- Other search functions include Incremental search, Search block/word, Search all buffers, Search all show/select.
- Block operations can be performed using Windows Clipboard or one of Vedit's 100 internal text registers. Or you can copy a block directly to another part of the file or to another file. Columnar blocks are supported. A special feature of Vedit is the persistent blocks that stay selected even if you move cursor.

- Vedit has C-like macro language. It is interpreted, so there is no need for compiling. This makes it easy to automate your tasks or to add new features to Vedit. In fact, many of the built-in functions of Vedit have been done using the macro language. The macros can be called from a file on disk, or you can add them to User or Tools menu or to any keyboard macro.
- Event macros can be executed automatically, for example on file open and close, mouse double-click etc. These can be used for example for automatic check-out / check-in from revision controlRevision controlRevision control, also known as version control and source control , is the management of changes to documents, programs, and other information stored as computer files.
