Shell

When running on a Unix-style operating system Jade allows you to run a shell subprocess in a buffer (usually the `*shell*' buffer). Each line you type in the buffer is sent to the shell and the output from the shell is displayed in the buffer.

Meta-x shell

Start a new shell subprocess running in a buffer called `*shell*'. If a buffer `*shell*' already exists a new buffer with a unique name will be opened (i.e. `*shell*<2>'). The working directory of the shell subprocess will be the directory which the contents of the current buffer was read from. This command won't work on Amigas!

Each `*shell*' buffer installs the major mode shell-mode. This provides the following commands.

Ctrl-a

Move the cursor to the beginning of the current line, after the prompt which the shell printed (if one exists).

Ctrl-d

If the cursor is at the end of the buffer send the shell process the eof character (`^D') (signifying the end of the file). Otherwise delete the character under the cursor.

RET

Send the current line to the shell (minus any prompt at the beginning of the line). If the cursor is not on the last line of the buffer (i.e. the most recent prompt) the current line is copied to the end of the buffer before being sent.

Ctrl-c Ctrl-n

Move the cursor to the next prompt in the buffer.

Ctrl-c Ctrl-p

Move to the previous prompt.

Ctrl-c Ctrl-c

Send the intr character (`^C') to the shell process.

Ctrl-c Ctrl-d

Send the eof character (`^D') to the shell.

Ctrl-c Ctrl-z

Send the susp character (`^Z') to the shell.

Ctrl-c Ctrl-\

Send the quit character (`^\') to the shell.

Hook: shell-mode-hook

This hook is evaluated by the Shell mode after it has initialised itself (and started its subprocess).

The following variables customise the actions of the Shell mode.

Variable: shell-file-name

This variable defines the file name of the shell to run. Its default value is either the value of the environment variable SHELL or if that doesn't exist the file `/bin/sh'.

Variable: shell-whole-line

When this variable's value is non-nil the RET command always sends the whole of the current line (minus any prompt) even when the cursor is not at the end of the line. Otherwise only the part of the line before the cursor is sent.

The default value of this variable is t.

Variable: shell-prompt-regexp

This buffer-local variable defines the regular expression used to match the prompt printed by the shell each time it waits for you to enter a shell command. By default it has the value `^[^]#$%>)]*[]#$%>)] *' but this may be incorrect if you have modified your shell's prompt.
