CHANGES recommended by Brent Fulgham 14/03/05

Slightly modified versions of

pop-mode.el

pop-help-mode.el

Both have (require 'cl) added

CHANGES in version 2.3, released 01/09/99

1. Revised the documentation (see the file emacs in this directory).

2. Added the process communication commands (pop-send-define,

pop-send-region, pop-send-buffer and pop-load-file) to the pop-help-mode

keymap. This is useful when reading TEACH files, which need to be

compiled.

3. Added two new functions, pop-delchar-or-maybe-eof and pop-send-eof. The

comint-mode for XEmacs 19.15 is broken: killing the process leaves an

extent after the process mark with closed ends. As a result any final

output from the process or from a subsequent process run in the same

buffer appears in comint-input-face. This doesn't catch all the ways the

process can be killed without cleaning up the extent in the inferior pop

buffer, but it fixes the most common problem.

4. Revised font-lock regular expressions to handle class, method and rule

declarations.

5. Added two new functions, pop-insert-file-header and

pop-add-revision-log-entry, for adding file headers and maintaining

revision logs in the `standard' Sussex/Birmingham format.

6. Fixed the C-h pop-help-mode bindings for XEmacs (thanks to Lieven

Marchand <mal@bewoner.dma.be>).

CHANGES in version 2.2, released 20/12/96

1. Fixed a bug in pop-end-of-sexp that caused it to go into an infinite loop

when trying to find the end of an unclosed syntactic structure at the end

of a buffer. The bug was probably introduced when I optimised rjc's

version.

2. Added a new variable to inferior-pop-mode to control initialisation of

the inferior Poplog process. If the variable inferior-pop-initialisation

is nil, Emacs will assume that Poplog will do the necessary

initialisation itself, e.g. in the user's init.p file. The default value

is t. If you do set this to nil in your .emacs file, you *must* include

the code in the file example-init.p for the Emacs/Poplog communication to

work properly.

3. Fixed a bug that resulted in compilation output appearing at the wrong

place in the inferior pop buffer (output appeared at point rather than at

the process mark).

4. Revised pop-help-mode to cope with most of the new formatting and graphics

characters which appear in the Poplog v15.5 help files.

5. Other minor fixes and revisions to pop-help-mode (thanks to Stephen Eglen

<stephene@cogs.susx.ac.uk> for code and suggestions).

CHANGES in version 2.1, released 30/10/96

1. pop-mode now uses an up to date version of comint mode and as a result no

longer breaks shell mode and other modes that depend on comint mode.

2. Much of the code that handles the inferior pop process has been rewritten

in an attempt to eliminate problems caused by sending requests to pop

when it is not a top level. As a result, when compiling pop code, Emacs

will lock up until pop is back at top level or generates some output.

This can occasionally be a problem on a slow machine when compiling very

large files from an Emacs buffer or compiling files that load a large

number of libraries (compiling files by issuing commands to pop in the

inferior pop buffer, e.g. typing "lib popvision;" at the prompt in the

inferior pop buffer is not a problem). To avoid this, set the variable

inferior-pop-timeout to nil. Note however that this disables all of

pop-mode's pre-compilation checks and can result in text being dumped

onto the stack if you try and compile something (or ask for help or

completions) while your pop program is executing.

3. inferior-pop-mode now handles multiple windows onto the inferior pop

buffer correctly: point no longer jumps to the end of the buffer when

compiling pop code from emacs.

4. If the variable pop-compilation-messages is nil, inferior-pop-mode no

longer writes the `;;; Compiling procedure from foo.p' comments in the

inferior pop buffer (it writes a message in the minibuffer instead).

5. pop-mode and inferior pop mode buffers now add menus to the menubar (this

is only available if you are running under X).

6. pop-mode now defines default regexps for font-lock.

7. pop-help-mode has been largely rewritten and the interaction model has

changed. By default pop-help-mode creates one buffer for each type of

help file HELP, TEACH etc. Making pop-help-always-create-buffer non nil

creates a new buffer for each file and it is up to the user to manage the

resulting buffers.

8. pop-help-mode now searches the REF indices if it can't find a help file

for a keyword.

9. pop-help-mode now copes with `modern' Poplog help files: it (should)

understand the new numeric syntax for file indices as well as the old `--'

form. It also removes the control characters that Ved uses for

formatting before displaying the help buffer.

10.Like Ved, pop-help-mode now uses the Poplog searchlists to decide

which directories to search for help files. This is generally a Good

Thing but a) it can be slow and b) it won't find help files which are not

in the default searchlists and where the corresponding library hasn't been

loaded. If you don't like this behaviour, you can set

pop-help-always-use-defaults to t and redefine the default searchlists in

your .emacs to include the help directories for the libraries you use.

11.For XEmacs users the variable pop-use-pl1-comments is gone, since XEmacs

can understand both comment styles.
