Signature

(gnuplot-context-sensitive-mode &optional ARG)

Documentation

Use context-sensitive completion and help in gnuplot-mode.

When context-sensitive mode is enabled, gnuplot-mode tries to provide more useful completions and help suggestions for built-in keywords and functions by parsing each command as you type. It attempts to take into account Gnuplot's many abbreviated keywords. For example, with point at the end of a line reading
"plot \\='datafile\\=' w ", typing M-x completion-at-point (completion-at-point) will pop
up a list of plotting styles.

Key bindings:

M-x completion-at-point (completion-at-point) will complete the keyword at point based on its context in the command. To make keyword completion work on pressing TAB, set tab-always-indent to complete.

M-x gnuplot-context-info-at-point (gnuplot-context-info-at-point) will try to find the most relevant Gnuplot info node for the construction at point, prompting for a node name if nothing is found.

M-x gnuplot-context-help-at-point (gnuplot-context-help-at-point) will pop up a brief summary of the syntax at point in the minibuffer. To have one-line syntax summaries appear in the echo area as you type, toggle eldoc-mode(var)/eldoc-mode(fun).

To choose whether to use this mode by default in Gnuplot buffers, customize the variable gnuplot-use-context-sensitive-completion.

This is a minor mode. If called interactively, toggle the Gnuplot-Context-Sensitive mode mode. If the prefix argument is positive, enable the mode, and if it is zero or negative, disable the mode.

If called from Lisp, toggle the mode if ARG is toggle. Enable the mode if ARG is nil, omitted, or is a positive number. Disable the mode if ARG is a negative number.

To check whether the minor mode is enabled in the current buffer, evaluate the variable gnuplot-context-sensitive-mode(var)/gnuplot-context-sensitive-mode(fun).

The mode's hook is called both when the mode is enabled and when it is disabled.
