What is Ce/Ceterm?

Ce/Ceterm is...
ARPUS/Ce is an integrated ascii text editor and X based terminal emulator modeled after the editor and terminal emulator on Apollo Domain systems. The ce tool is a robust and extensible programmer's editor. The ceterm tool is meant to be a replacement for vendor-supplied X-based terminal window programs such as IBM's "aixterm", HP's "hpterm", DEC's "decterm", and Sun's "Shell Tool". It is also suitable for use as a PAGER, replacing the UNIX "more" command and supplying an interface which models the Apollo Domain systems. The general reaction of former Apollo users to ARPUS/Ce is "Yes, this is what I was looking for."

The Ce editor is written as a standard X appliction. This makes the program portable. This portability is evidenced by the number of platforms Ce is available on. It's performance makes it one of the fastest products available. It is also easy to customize, making it useful for both the novice and expert user.

NOTE: At release 2.6, the major releases of ce/ceterm do not need to be setuid'ed. Improvements in pseudo-terminal system code have removed this requirement. Not being setuid'ed as root prohibits ceterm from updating UTMP on startup which means the session will not show up in the who command. The who command is a poor excuse for running setuid'ed so it is recommended that the program not be setuid'ed.

The Ce editor has the ability to let multiple designers on multiple platforms edit the same file at the same time and see each other's changes as they are being typed.

Documentation is provided in a users guide, help files modeled after those used on the Apollo Domain systems, and HTML documentation. The HTML documentation is a self contained package. Once installed, it only needs one pointer to this the Ce home page. The HTML documentation also contains an index of all the help files and the users guide.

Ce is written with a mindset of not wasting real estate on the screen. This allows the maximum number of text lines to be viewed at one time.

Status of Ce -- Jan 2005

Ce in binary form is distributed freely. It is no longer connected to a license manager. No warrentee or indemnity is supplied in the free version. Fixes and support will be provided on as time allows. Maintenance my be purchased, in which case every effort will be made to resolve any problems quickly and satisfactorily.

Commercially supported Hardware/OS platforms

Other ports

The binaries for Ce are supplied free of charge. Support contracts may be purchased through (stymarAtcoxdotnet) Robert Styma Consulting. Questions are welcome. "Can Ce do this and how do I build a key defintion to do something type questions can be submitted to stymarAtcoxdotnet Bob or Bob at work


Performance

Ce/Ceterm has the following limits
 

*   - Subject to available swap space.
**  - Variations based on length of lines.
*** - initial file size, you can still add lines.

What's new in release 2.6.2

Notes on setting up Linux (Gnome) front panel startup and hot keys for ceterm

This is a summary of changes from Ce release 2.6.1 to 2.6.2 (12/14/2005)

NOTEWORTHY BUG FIXES AND ENHANCEMENTS:

A bug introduced in release 2.6.1 caused certain command syntax error messages to be trucated to 4 bytes. This has been corrected.

When you press the CDE "Exit" button under Solaris 9, it sends a SIGHUP interupt instead of a "WM_SAVE_YOURSELF" message. Ce now traps this signal and creates a crash file (.CRA) if there are unsaved changes.

Under the Gnome environment (Linux and Solaris), Ce is now able to correctly save its state when you log off. Before, you would get a message about having to restart the service manually. Now Ce complies with the XSMP protocol so it handles this correctly. Support for the KDE environment under Linux is improved.

Note that there are now separate Solaris 2.8 and 2.9 versions of ce. The 2.8 version works fine on 2.9 but not the other way around. The 2.9 version of Ce contains calls to the XSMP (X Session Manager Protocol) code which was added in Solaris 2.9. It is used with the Gnome desktop so that you can save the current session. If you are only using CDE, you can use the Solaris 2.8 version across the board.

NEW ARGUMENTS AND X RESOURCES:

-bell {y | n | visual | VISUAL}
Ce.bell : {y | n | visual | VISUAL}
This option defaults to 'y'. Setting the value to "n" suppresses the generation of an audible beep on certain events. Setting the value to "visual" causes the window to flash reverse video instead of making a noise. A lower case "visual" flashes the DM Output window. An uppper case "VISUAL" flashes the main window. Note that only the first character of "y", "n", "visual", and "Visual" is examined.


This is a summary of changes from Ce release 2.6 to 2.6.1 (07/25/2005)

NOTEWORTHY BUG FIXES AND ENHANCEMENTS:

Security fixes.
A buffer overflow was found in ce/ceterm which could be exploited to get root access on a machine if the ceterm was setuided to root. ceterm does not need to be setuid'ed on any supported platform. It is recommended that the setuid be dropped on any existing copies of Arpus/Ce. One side affect of dropping the setuid is that ceterm will not be able to update the utmp file and thus will not appear in listings produced by the who command. The who command is a poor excuse to run setuid'ed. Earlier versions of UNIX OS's required the setuid to open a pseudo-terminal. The buffer overflows have been corrected.

NEW CE COMMANDS:

cntlc
Special command to place under the <ctrl>-c key (press and hold the Ctrl key and then press c). Many editors use the <ctrl>-c sequence to do a copy to the clipboard. However, terminal emulators use <ctrl>-c as an interupt. The cntlc command morphs into an interupt if the window is a ceterm and there is no text highlighted. Otherwise it morphs into a copy command. This is the default in new installs. For existing $HOME/.Cekeys files, it is recommended that you replace the definition for ^c with:
 
kd ^c cntlc -h ^c PRIMARY ke

Release 2.6 contains the following changes: (3/28/2005)

NOTEWORTHY BUG FIXES AND ENHANCEMENTS:

Scrolling on highlighted drag.
By default, the left mouse button highlights the text it is dragged over on press and does a copy on release. The added behavior is that if you drag the mouse out of the window, the window will begin scrolling in that direction.

Updates to use the new pseudo terminal calls in Linux Fedora Core 2 (Available since Redhat 8) are added. The old way stopped working on Fedora Core 2. Also added to the RS6000 AIX version.

NEW CE COMMANDS:

reload
Reload file from disk. This command deletes the current memory copy of the file and replaces it with a fresh copy loaded from disk. If the memory copy of the file has been changed, a confirmation prompt is requested. A prompt for this command to be executed is generated when ce detects that the disk copy of the file has been changed external to ce.

NEW OPTIONS TO EXISTING CE COMMANDS:

-l option to xp
The -l option has been added to the xp command. It causes the cursor to be placed at the end of the pasted area rather than the beginning. It is ignored if the -r option is specified.
kd F4 ax -l ke # paste and put cursor at end


Page Updates

09/09/2004
Added Release compiled for Fedora Core 2. This release will work on Red Hat 8, Red Hat 9, and Fedora Core 1 also. This release for Linux does not require setuid.

New features

The release help contains the list of differences from one release to the next.

Release 2.5.5 contains the following changes:

Ceterm support for Linux is improved. Linux colorization controls output by ls and other commands are handled. (Be careful of colorizing to the background color).

Modifications to support oddities of the Hummingbird Exceed window manager have been added.

The X Resource Ce.vcolors has been added to allow the selection of the colors used in Linux colorization. The default is the colors used in a gnome terminal.
