199 #bSPARCworks Editor Integration#n
|
|
|
200 Eos is copyright (c) 1995 by Sun Microsystems.
|
|
|
201
|
|
|
202 #bIntroduction (for Eos 1.5.x)#n
|
|
|
203
|
|
|
204 #iSPARCworks#n is a set of integrated programming tools from SunSoft that
|
|
|
205 support the program development cycle. #iXEmacs#n is a version of the Emacs
|
|
|
206 editor that includes interfaces to the selection service and to the
|
|
|
207 #iToolTalk#n service. The #iEos#n package uses these two interfaces to provide
|
|
|
208 a simple yet useful editor integration with three SPARCworks tools:
|
|
|
209 the #iSourceBrowser#n, the #iDebugger#n and #iDbx#n. Eos requires XEmacs 19.12
|
|
|
210 or above, and SW3.0.1 or above.
|
|
|
211
|
|
|
212 When used with Eos, the Debugger and SourceBrowser do not include a
|
|
|
213 source pane for displaying of sources and instead use an XEmacs frame.
|
|
|
214 Then the user can interact with the XEmacs frame in a way very similar
|
|
|
215 to how the source panes of the SW tools would be used. The user can also
|
|
|
216 start Dbx and request that sources be shown in XEmacs.
|
|
|
217
|
|
|
218 #bSimple Startup#n
|
|
|
219
|
|
|
220 In most cases, the user will start an interaction with Eos as follows:
|
|
|
221
|
|
|
222 (1) Start XEmacs,
|
|
|
223
|
|
|
224 (2) Load \"eos.el\" to add a SPARCworks submenu to the menubar (this
|
|
|
225 step might not be needed if Eos is preloaded to your XEmacs binary), and
|
|
|
226
|
|
|
227 (3) On some XEmacs frame use the SPARCworks submenu and start the
|
|
|
228 desired tool and simultaneously enable that frame to display sources.
|
|
|
229
|
|
|
230 The toolbar for the enabled frame will change after (3) to show that
|
|
|
231 this frame will behave as the source display for the SW tool and to
|
|
|
232 indicate that some actions on the tool can be performed from this frame.
|
|
|
233
|
|
|
234 The actions available depend on the SW tool. The interaction model for
|
|
|
235 the Debugger and the SourceBrowser can be described as #iselect on the
|
|
|
236 XEmacs frame and then click on the button on the SW tool#n. As an example,
|
|
|
237 a browser query can be performed by selecting some text and then clicking
|
|
|
238 on the query button on the SBrowser tool; the source for the first match
|
|
|
239 will appear in the XEmacs frame, together with a glyph showing the match.
|
|
|
240
|
|
|
241 The Debugger and Dbx can also be driven from XEmacs. Most frequently
|
|
|
242 this will be done using the ToolBar. Entries in the toolbar of a frame
|
|
|
243 enabled for debugging are deactivated when there is not enough information
|
|
|
244 to invoke their associated commands (due to technical reasons, it is
|
|
|
245 necessary for XEmacs to have had a frame enabled for Debugger/Dbx when
|
|
|
246 a debug or attach command was issued to Debugger/Dbx to make most toolbar
|
|
|
247 commands active). As an example, to set a breakpoint at some line, select
|
|
|
248 a position in that line and then click on the toolbar icon with the stop
|
|
|
249 with the arrow inside.

|
251 #bDetails#n

|
|
252
|
|
|
253 #iManual Startup#n
|
|
|
254
|
|
|
255 In the scenario described above, the user simultaneously starts a tool
|
|
|
256 and enables a frame for that tool. The two actions can also be done
|
|
|
257 independently. The tools (Source Browser, Debugger, and Dbx) have to
|
|
|
258 be started with the \"-editor\" option and the XEmacs frame can be
|
|
|
259 enabled manually using the SPARCworks submenu. The most common use
|
|
|
260 of this feature is to disable and re-enable a frame, be it to recover
|
|
|
261 the default toolbar, or to avoid conflicts with other active tools
|
|
|
262 (see the paragraph below on multiple active tools).
|
|
|
263
|
|
|
264 #iFrame Enabling#n
|
|
|
265
|
|
|
266 At any given time there can be at most one frame enabled to display
|
|
|
267 Source Browser sources, and at most one frame enabled to display
|
|
|
268 Debugger and Dbx sources. The same XEmacs frame can be used for both
|
|
|
269 types of sources. The toolbar of an enabled frame always starts with
|
|
|
270 an informational icon. This icon is a large-font #ii#n with either a
|
|
|
271 smaller-font #iB#n, if the frame has browsing enabled, and/or a smaller-font
|
|
|
272 #iD#n, if the frame has debugging enabled.
|
|
|
273
|
|
|
274 If no frames are enabled for a given tool, the editor integration for
|
|
|
275 that tool is disabled. This means that XEmacs deregisters the TT
|
|
|
276 patterns relevant to this tool, and XEmacs does not receive any
|
|
|
277 messages from that tool.
|
|
|
278
|
|
|
279 #iMultiple Active Tools#n
|
|
|
280
|
|
|
281 In order to provide a simpler user model, Eos has no provisions to
|
|
|
282 #igracefully#n support more than one simultaneous active tool of a
|
|
|
283 given class per TT session. A Debugger and a SourceBrowser, or a Dbx
|
|
|
284 and a SourceBrowser, can coexist gracefully, but a Debugger and a Dbx
|
|
|
285 cannot, and neither can two SourceBrowsers, two Debuggers, or two
|
|
|
286 dbxs. This simplification is consistent with the needs of most users.
|
|
|
287
|
|
|
288 The implementation of Eos notifies the user if she attempts to start two
|
|
|
289 conflicting tools, but it does not enforce the restriction. In some
|
|
|
290 cases two conflicting tools can be used profitably by a careful user,
|
|
|
291 but in others the result is likely to be chaos. An example of the first
|
|
|
292 is using two SourceBrowsers, and one of the later is attempting to send
|
|
|
293 debugging commands from XEmacs to two debuggers.
|
|
|
294
|
|
|
295 If a user really needs to have multiple active tools, she can do this
|
|
|
296 in a safe way by creating several TT sessions (e.g. using #ittsession
|
|
|
297 -c /bin/csh#n, see the man page for ttsession), and placing the tools
|
|
|
298 with their own XEmacses in separate TT sessions.
|
|
|
299
|
|
|
300 #iA Visual Data Inspector in XEmacs#n
|
|
|
301
|
|
|
302 Users that choose to drive the debugger from XEmacs also have
|
|
|
303 available a #ivery simple#n but fast visual data inspector. The results
|
|
|
304 of #iprint#n and #iprint*#n commands are formatted into an XEmacs buffer
|
|
|
305 (#i\"*Eos Print Output*\"#n) and presented into a separate frame.
|
|
|
306 This frame is mapped and unmapped so that, except for the first time,
|
|
|
307 it appears quickly.
|
|
|
308
|
|
|
309 #iBuffers for Debugger/Dbx Interaction#n
|
|
|
310
|
|
|
311 When starting dbx as a subprocess, a buffer will be created to interact
|
|
|
312 with dbx. The name of this buffer is of the form #i\"*Eos dbx*\"#n.
|
|
|
313
|
|
|
314 If a dbx engine is receiving requests from both Debugger and XEmacs
|
|
|
315 (e.g. it was started via #idebugger -editor#n), the responses to
|
|
|
316 commands sent by XEmacs will be shown in the echo area and will be
|
|
|
317 recorded in a read-only buffer (#i\"*Eos Debugger Log*\"#n), but responses
|
|
|
318 to Debugger commands will not appear. Conversely, responses to Debugger
|
|
|
319 commands will appear in the Debugger transcript pane but not in XEmacs's
|
|
|
320 log buffer. This is a limitation of the underlying TT protocols.
|
|
|
321
|
|
|
322 #bTTY Support#n
|
|
|
323
|
|
|
324 Although tty support is not an official part of Eos, it is possible
|
|
|
325 with some extra effort and specialized knowledge from the user.
|
|
|
326
|
|
|
327 #iStarting a ToolTalk Session#n
|
|
|
328
|
|
|
329 Eos requires a ToolTalk communication. This may require starting a TT
|
|
|
330 session by:
|
|
|
331
|
|
|
332 (0) Start a ToolTalk session, and a shell so that all processes
|
|
|
333 started from this shell will use the new TT session. Do this by
|
|
|
334 executing \"ttsession -c /bin/csh\" - or whatever shell you use
|
|
|
335
|
|
|
336 At this point, you can start your XEmacs on that shell, as shown in
|
|
|
337 step (1) above. Note that, since there is no TTY toolbar in 19.12
|
|
|
338 (nor 19.13), an alternative mechanism must be used to enable the
|
|
|
339 (tty) frame.
|
|
|
340
|
|
|
341 A typical use for tty is to interact with dbx. The command
|
|
|
342 #ieos::start-dbx#n will select the tty frame for debugging and will start
|
|
|
343 a dbx buffer. From this point on, dbx will use this tty frame to show
|
|
|
344 its sources. The introduction and news messages can be generated
|
|
|
345 using the commands #ieos::sw-intro#n and #ieos::sw-news#n. You can interact
|
|
|
346 with the dbx subprocess by typing to its associated input buffer or
|
|
|
347 using some key bindings.
|
|
|
348
|
|
|
349 #iKey Bindings#n
|
|
|
350
|
|
|
351 A tty user can interact with Eos by invoking directly the Eos
|
|
|
352 commands, evaluating elisp expressions, or through some key-bindings.
|
|
|
353 The expert user may provide her own key bindings. Eos also provides two
|
|
|
354 set of global bindings, which are activated by evaluating the
|
|
|
355 expressions (eos::set-key-mode 'prefix) or (eos::set-key-mode
|
|
|
356 'function).

|
|

|
358 #bKnown Bugs#n
|
|
|
359
|
|
|
360 Due to a bug in the internal subprocess machinery of XEmacs 19.12, the
|
|
|
361 default prompt of dbx subprocesses will show the full path to the binary.
|
|
|
362 The prompt can be overridden using the ksh variable PS1\; one way to do
|
|
|
363 this is by adding the following line to your ~/.dbxrc:
|
|
|
364
|
|
|
365 PS1='(dbx) '

469 Support for 19.12 and 19.13. Works on TTYs. Uses real ToolBar.
|
|
|
470 Toolbars for debugger & content inspector are frame-local.
|
|

471 Better icons and glyphs. Support for (load-library \"eos\").
|

472 Ease-of-use: startup for tools.
|
|

473 Icon files are now defined \"in-line\" to simplify administration.

474
|

475 Removed the following to simplify use:
|
|
|
476 - Textual toolbar (from 1.4).
|

|
477 - Option submenu to add keymaps for debugger use.
|
|
|
478 - Popup menu.
|
|
|
479 - Any pretenses to support SW3.0; use SW3.0.1 instead.

493 for displaying debugged sources.
|
|
|
494
|
|

495 Added a command to relayout debugger buffers so they show in

502 selectable via options.
|

503

504 The *debugger* buffer now support M-p and M-n.

516
|

517 Some internal cleanup.
|
|
|
518
|
|
|
519 Eos now provides basic machinery to drive the debugger
|
|
|
520 engine directly using ToolTalk messages. This feature is
|
|
|
521 not yet very well polished. You can try using it at your own risk,
|
|
|
522 or await for release 1.2 (soon to come) that will provide a better
|
|
|
523 interface and improved functionality, as well as documentation
|
|
|
524 for the interface.

525

528 First widely available release. Supports simple #iselect and click#n model.

|
|
529
|
|
|
530 #bPossible Future Enhancements#n
|
|
|
531
|
|
|
532 * Add a \"peek-in-source\" mechanism to show the values of
|
|
|
533 expressions in the sources.
|
|
|
534
|
|
|
535 * The comint package should be generalized to allow for TT-based
|
|
|
536 interpreters and it should be used in Eos.
|
|
|
537
|
|
|
538 * Key & popup bindings should probably be a minor mode (currently
|
|
|
539 it conflicts with cc-mode).
|
|
|
540
|
|
|
541 * Should support locking a print frame to force new print frames. Also,
|
|
|
542 should allow for following fields in print frames.
