Major mode for editing BASIC code
This package provides a major mode for editing BASIC code. Features
include syntax highlighting and indentation, as well as support for
auto-numbering and renumering of code lines.
You can format the region, or the entire buffer, by typing C-c C-f.
When line numbers are turned on, hitting the return key will insert
a new line starting with a fresh line number. Typing C-c C-r will
renumber all lines in the region, or the entire buffer, including
any jumps in the code.
Type M-. to lookup the line number, label, or variable at point,
and type M-, to go back again. See also function
`xref-find-definitions'.
Installation:
The recommended way to install basic-mode is from MELPA, please see
https://melpa.org.
To install manually, place basic-mode.el in your load-path, and add
the following lines of code to your init file:
(autoload 'basic-mode "basic-mode" "Major mode for editing BASIC code." t)
(add-to-list 'auto-mode-alist '("\\.bas\\'" . basic-mode))
Configuration:
You can customize the indentation of code blocks, see variable
`basic-indent-offset'. The default value is 4.
Formatting is also affected by the customizable variables
`basic-delete-trailing-whitespace' and `delete-trailing-lines'
(from simple.el).
You can also customize the number of columns to allocate for
line numbers using the variable `basic-line-number-cols'. The
default value of 0 (no space reserved), is appropriate for
programs with no line numbers and for left aligned numbering.
Use a positive integer, such as 6, if you prefer right alignment.
The other line number features can be configured by customizing
the variables `basic-auto-number', `basic-renumber-increment' and
`basic-renumber-unnumbered-lines'.
