Detailed Description

Functions defining the commandline builtin.

Functions used for implementing the commandline builtin.

Enumeration Type Documentation

anonymous enum

Which part of the comandbuffer are we operating on.

Enumerator:

STRING_MODE	Operate on entire buffer.
JOB_MODE	Operate on job under cursor.
PROCESS_MODE	Operate on process under cursor.
TOKEN_MODE	Operate on token under cursor.

anonymous enum

For text insertion, how should it be done.

Enumerator:

REPLACE_MODE	Replace current text.
INSERT_MODE	Insert at cursor position.
APPEND_MODE	Insert at end of current token/command/buffer.

static void replace_part	(	const wchar_t *	begin,
		const wchar_t *	end,
		wchar_t *	insert,
		int	append_mode
	)			[static]

Replace/append/insert the selection with/at/after the specified string.

Parameters:

	begin	beginning of selection
	end	end of selection
	insert	the string to insert
	append_mode	can be one of REPLACE_MODE, INSERT_MODE or APPEND_MODE, affects the way the test update is performed

static void write_part	(	const wchar_t *	begin,
		const wchar_t *	end,
		int	cut_at_cursor,
		int	tokenize
	)			[static]

Output the specified selection.

Parameters:

	begin	start of selection
	end	end of selection
	cut_at_cursor	whether printing should stop at the surrent cursor position
	tokenize	whether the string should be tokenized, printing one string token on every line and skipping non-string tokens
