A is a text editor inspired by the Sam and Acme text editors for the Plan 9 operating system.
- Latest Binaries
- Written in Go (no dependencies)
- Graphical (http://github.com/as/frame)
- Not CGo
- Not a port/transpilation
- Resembles Acme and Sam text editors.
- Mouse chording
- Text is executable
- Standard UNIX keyboard shortcuts
- Implements the Edit command language
- Frame implementation stores bytes and works with '\0'
- UTF-8 rendering support
- Structure highlighting
- Image support (TBD)
- Optimized for editing huge binary files.
This repository is still in the alpha stage, and frequently changes. The program comes with no warranty expressed or implied.
install or build
Binary releases for linux, windows, and darwin are available for v0.6.7+. You can install from source on these systems by running:
go get -u -t github.com/as/a
If you want to install a prior version (v0.5.5, for example, which uses the original exp/shiny)
go get github.com/as/a go get github.com/golang/vgo cd $GOPATH/src/github.com/as/a git checkout v0.5.5-release vgo build
You can also build the latest with vgo, but vgo is not necessary for that
git checkout master vgo build
a [file ...]

To reshape the windows and columns, click on the invisible 10x10px sizer that I haven't rendered yet with the left mouse button. Hold the button down and move the window to the location. Release the button.
- 80% of the sam command language is implemented.
