Oddly enough, this had also occurred to me yesterday as a useful improvement. I was thinking of a global list of functions not to be traced, but your symbol property approach seems like a good idea as well. Perhaps "both" is good. For symbol properties I think there would need to be a variable to control whether or not that was respected, to make it relatively easy to force them to be traced regardless. > I wouldn't use `tramp' as example for `trace-library'. No problem. I think the example dates back to the info on tracing which used to appear in (info "(tramp) Traces and Profiles") but I'd noticed that had been deleted when I was rebasing this work. -Phil

Yes, and I also agree with the comments of Eli.
One additional point:

Tramp does something like this already. However, not all Tramp functions
shall be traced. For example, there is `tramp-read-passwd', which
returns the password retireved from auth-sources, or
interactively. Obviously, it shouldn't be traced when asking users for a
Tramp trace.
There are also chatty functions, which don't need to be traces, like
`tramp-message' and friends. They add serious noise to the trace, w/o
additional information.
For that reason, Tramp marks such functions with a function property,
which is to be taken into account when activating traces for all Tramp
functions. Like this:
--8<---------------cut here---------------start------------->8---
(put #'tramp-read-passwd 'tramp-suppress-trace t)
--8<---------------cut here---------------end--------------->8---
I would appreciate if `trace-package' and `trace-library' would know a
similar mechanism. It could be a function declaration in the function
definition, like
--8<---------------cut here---------------start------------->8---
(declare (debug t) inhibit-trace ...)
--8<---------------cut here---------------end--------------->8---
Or, dynamically, the global variable inhibit-trace could keep a value of
such functions suppressed for trace.
Of course there is `untrace-function', but it is inconvenient to teach
users calling all of them. And if they forget it, their password will be
exposed (for example).

I wouldn't use `tramp' as example for `trace-library'. Tramp consists of
a dozen of libraries, and several of them must be activated in order to
get useful traces. So as example, another library might be better
suited.

Yes, it is useful.
The documentation uses UK English spelling ("behaviour"). (Perhaps
today this is justified, but since a few days will have passed until
this is landed, I think we should use US English conventions
nonetheless.)
I see lack of important detail where stuff like 'context' and
'trace-value' is described: at the very least the manual should say
whether the text will be inserted verbatim, or with something like
newlines and/or other decorations added.
IMO, the description of trace-value should be before all the untrace-*
functions.
Why isn't trace-is-traceable-p documented in the manual? It sounds
relevant to the discussion of the restrictions.
I think the description should be updated fore native-compilation (it
only mentions byte-compilation).
The hunk from modes.texi seems unrelated.
The NEWS entry should have a single-line heading that is a full
sentence ending with a period.
Please verify that doc strings of functions mention all the
arguments. (E.g., trace-currently-traced doesn't.)
Thanks.

+You can trace the execution of functions using the tracing facilities
+provided by the @file{trace.el} library. Many functions can be traced
+at the same time. The commands @code{trace-function-foreground} and
+@code{trace-function-background} add a new trace to a single specified
+function. The commands @code{trace-package}, @code{trace-regexp}, and

+Traces can also be added to autoloaded functions -- the associated

+
+@vindex trace-buffer
+Calls to traced functions, including the values of their arguments and

+Optional @var{context} expressions are also evaluated, both when the

+or return value respectively. This could be used to track the current
+buffer or position of point, for instance. If @var{context} is a
+function, it will be called (with no arguments) to obtain the value to
+be inserted into the trace output buffer.

+@itemize @bullet

+Only functions/macros/subrs that are called via their function cell
+will generate trace output; hence, you won't get trace output for:
+
+@itemize @bullet
+@item
+Macros that were expanded during compilation.
+
+@item
+Subrs called directly from other subrs/C-code.
+
+@item
+Byte-compiled calls to subrs that have special byte-codes associated
+with them:
+
+@example
+(sort (cl-loop for sym being the symbols
+ if (and (subrp (symbol-function sym))
+ (plist-get (symbol-plist sym)
+ 'byte-opcode))
+ collect sym)
+ (lambda (s1 s2)
+ (string< (symbol-name s1) (symbol-name s2))))
+@end example
+@end itemize
+
+@item
+Tracing too many functions at one time will render Emacs unusable. Do
+not attempt to trace all functions, and take care with the arguments
+passed to the bulk tracing commands @code{trace-package} and
+@code{trace-regexp}.
+
+@item
+Foreground tracing should not be used to trace functions that switch
+buffers, or have other display-oriented behaviour.
+
+@item
+Each function can only be subject to a single trace. When a function
+which is already being traced is targeted by any tracing command, the
+new trace criteria (including optional argument values) will replace
+the previous trace criteria for that function.
+
+Note that this also means there is no need to un-trace a function in
+order to re-trace it with different arguments.
+
+@item
+All the restrictions that apply to @file{nadvice.el} also apply to
+tracing (as tracing is implemented using advice). @xref{Advising
+Functions}.
+@end itemize
+
+@node Examples of Tracing
+@subsection Usage examples for function tracing
+
+The following is example trace output, including a context list
+expression, for a function which also makes a call to
+@code{trace-values}. The left hand column indicates the evaluation
+depth of the function call.
+
+@example
+@group
+1 -> (funcname arg1 arg2) [(context1 context2)]
+1 -> (trace-values value1 value2)
+1 <- funcname: return [(context1 context2)]
+@end group
+@end example
+
+The trace output display of recursion/nesting levels can be
+demonstrated by tracing a recursive function, such as a simplistic
+factorial implementation:
+
+@example
+@group
+(defun fact (n)
+ "Calculate factorial of N."
+ (if (eql n 0) 1
+ (* n (fact (1- n)))))
+ @result{} fact
+
+(trace-function 'fact)
+ @result{} fact
+
+Now, evaluating this...
+
+(fact 4)
+ @result{} 24
+
+...will generate the following in *trace-buffer*:
+
+1 -> fact: n=4
+| 2 -> fact: n=3
+| | 3 -> fact: n=2
+| | | 4 -> fact: n=1
+| | | | 5 -> fact: n=0
+| | | | 5 <- fact: 1
+| | | 4 <- fact: 1
+| | 3 <- fact: 2
+| 2 <- fact: 6
+1 <- fact: 24
+@end group
+
+Try the following for some more interesting trace output:
+
+@group
+(defun ack (x y z)
+ (if (= x 0)
+ (+ y z)
+ (if (and (<= x 2) (= z 0))
+ (1- x)
+ (if (and (> x 2) (= z 0))
+ y
+ (ack (1- x) y (ack x y (1- z)))))))
+
+(trace-function 'ack)
+
+(ack 3 3 1)
+@end group

I did document these changes in the elisp manual to the extent that any of the trace functionality is documented (which is minimally). The key documentation would probably be for the functionality which was already present, rather than for the changes I've made here; so anyone familiar with trace.el might add that. I'll try to throw something together from commentary and docstrings in the near future though (including the new changes), assuming no one else does so first. -Phil

Meanwhile I was experimenting with load-history along these lines:
(require 'seq)
(defun trace-library (library)
"Trace functions defined by LIBRARY."
(mapcar 'trace-function-background
(mapcar 'cdr (seq-filter
(lambda (x)
(and (consp x) (eq (car x) 'defun)))
(load-history-filename-element
(load-history-regexp library))))))

It's up to Phil to decide what will be implemented. But as a power user of trace.el, I thought I bring my experience on table. Best regards, Michael.

We cannot assume that library 'foo prefixes all its functions with
"foo-". Even Tramp libraries have functions which do not fit this
scheme, for historical reasons.
So we shall parse indead every function for the library it belongs to. It
shouldn't be too hard, based on `autoloadp', `find-lisp-object-file-name'
and friends, see the implementation in `describe-function-1'. Something
like this is a very rudimentary implementation:
(defun my-find-library (fun)
"Find library FUN is defined in.
In case of subroutines, return t"
(when (fboundp fun)
(let ((def (symbol-function fun)))
(cond
((autoloadp def) (cadr def))
((subrp def) t)
(t (file-name-base (find-lisp-object-file-name fun nil)))))))

Because we risk stopping now for a while and having two inconsistent functions in Emacs. It also adds a burden to the contributor who might now have signed up for tackling this particular challenge. There will also be some nuances to work out, I'm sure.

I don't believe it will be too hard to implement; why not doing it just now? Improving elp* could be a second step then. Best regards, Michael.

It shouldn't be too hard to evaluate this, though: (with-eval-after-load 'tramp (trace-package "tramp-")) And the current patch makes it easier. >> Perhaps you're actually be suggesting some kind of `eval-after-load' >> tracing behaviour, though? > > Yes, that's the idea.

Considering elp-instrument-package does not do that, I think we should limit the scope of the currently discussed patch, and trace only already loaded functions. If we do what you suggest, it should be a new discussion, and it should improve elp-instrument-package as well.

I concede that the name may cause some confusion, but I chose it for consistency with `elp-instrument-package' which uses the same function-name-prefix meaning, so the name makes sense from that perspective. Obviously ELP pre-dates package.el. YMMV. Maybe `elp-instrument-package' and `trace-package' should become `elp-instrument-prefix' and `trace-prefix' ?

I think `trace-library' would be the appropriate name? (If `trace-package' were about ELPA packages, then we have multi-file packages to consider, which expands the scope further.) Of course we can't guarantee that library foo.el adheres to a foo-* naming scheme for all its functions (or that other libraries don't define any foo-* functions). Would we just ignore this and trace everything starting with foo- on the assumption that this is good enough? Or would we parse the library in order to trace that library's functions precisely? > `trace-regexp', on the other hand, shall instrument the functions in > a form added to `after-load-functions', additonally to the functions > already loaded. Which could also apply to (the current meaning of) `trace-package'. I suppose this could potentially be an additional y-or-n-p prompt for the extended interactive argument input (after BUFFER and CONTEXT) when using a prefix arg. I think that the equivalent `untrace-*' commands would need to remove such `after-load-functions' entries by default, but perhaps a prefix argument to those would allow users to choose. I can see potential for users to end up with unwanted remnant entries in after-load-functions (e.g. trace-regexp "A\\|B", then untrace-regexp "A" and "B" separately), so I think there could be some fiddly aspects to all of this; although one could argue that anyone using these features in the first place is likely to know what they're doing, and would be able to cope with such situations easily enough; especially if `untrace-all' takes care of the after-load cases. -Phil

I'm not certain what you're asking here.
With respect to the manual entry being discussed here, we could
trivially show code to `require' all of the tramp-* libraries prior
to calling trace-package or trace-regexp. e.g.:
(mapc 'require '(tramp tramp-adb tramp-cache tramp-cmds
tramp-compat tramp-ftp tramp-gvfs tramp-sh
tramp-smb tramp-uu trampver))
(or else something which automatically locates library names starting
with "tramp-" and loads them all).
Perhaps you're actually be suggesting some kind of `eval-after-load'
tracing behaviour, though?

There's no package "tramp-". Better would be
(trace-regexp "^tramp-")
Could be changed in the Tramp manual (modulo backwards
compatibility). One problem I'm always faced with Tramp are autoloaded
functions. The code as given in the Tramp manual instruments only
functions, which are either already loaded, or which are marked as to be

Just attaching the current patch. Thanks for the input Dmitry and
Kaushal. I'll leave it a while to see whether anyone else wishes to
weigh in on the outstanding items:
* The inconsistent predicate naming of `trace-is-traced' vs
`trace-is-traceable-p'.
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27397#19
* Whether foreground-tracing variants of the new commands are wanted.
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27397#25
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27397#34
* Whether it's a good idea to display the trace buffer initially
when one of the background tracing commands is invoked.
(I guess I'll follow up next weekend if no one has anything to add
in the interim.)
-Phil

Subject: [PATCH] New commands for bulk tracing of elisp functions
* lisp/emacs-lisp/trace.el (trace-package, untrace-package)
(trace-regexp, untrace-regexp, trace-is-traceable-p): New functions.
(trace--read-function): New function, split from `trace--read-args'.
Changed to use the new `trace-is-traceable-p' predicate.
(trace--read-extra-args): New function, split from `trace--read-args'.
Changed to allow the user to enter an empty string at the context
expression prompt (previously an error; now treated as "nil"), and to
cause a "nil" context expression to produce no context output in the
trace buffer.
(trace--read-args): Removed function. Replaced by the combination of
`trace--read-function' and `trace--read-extra-args'.
(trace-function-foreground, trace-function-background): Updated
interactive specs to use the new functions.
(trace-is-traced, untrace-function, untrace-all): Doc updates/fixes.
Commentary updated to cover the new commands.
Change log updated to cover the main changes since 1993.
* etc/NEWS: Mention the new trace commands.
* doc/misc/tramp.texi: Update "(tramp) Traces and Profiles" to use
`trace-package'.

That was because the behaviour of `trace--read-args' had been quite
specific to the `trace-function*' commands -- its primary purpose was
to prompt for a single function -- and I thought the name should reflect
that. I agree with you, though -- the new name wasn't ideal either.
I've now refactored this like so:
* `trace--read-args' has been split into `trace--read-function` and
`trace--read-extra-args'.
* `trace--read-function` reads only a function.
* `The interactive specs for the trace-function*' commands are now
similar to those of the new bulk trace commands, in explicitly
calling `trace--read-extra-args':
(interactive
(cons (trace--read-function "Trace function: ")
(and current-prefix-arg (trace--read-extra-args))))
I think this name change makes better sense, and the code is now more
consistent between commands.

Sounds good. Why the rename, though? Those are not arguments for the function we're going to trace. trace--read-args sounds as appropriate, if not more.

I've implemented this change, and attached the current WIP patch.
In the process I noticed that the existing behaviour of trace--read-args
was quite unfriendly if you wanted to set a trace buffer but had no need
of a context expression -- typing RET at the context expression prompt
triggered an "End of file during parsing" error, as that input string
is processed by `read-from-string'.
I've changed that code to treat an empty input as "nil" (which is read
to `nil'), and to ignore `nil' context expressions entirely (as opposed
to printing their evaluated value as "[nil]" in the trace buffer).

Subject: [PATCH] New commands for bulk tracing of elisp functions
* lisp/emacs-lisp/trace.el (trace-package, untrace-package)
(trace-regexp, untrace-regexp, trace-is-traceable-p): New functions.
(trace--read-extra-args): New function, split from `trace--read-args'.
Changed to allow the user to enter an empty string at the context
expression prompt (previously an error; now treated as "nil"), and to
cause a "nil" context expression to produce no context output in the
trace buffer.
(trace--read-function-args): New name for `trace--read-args'.
Changed to use the new `trace-is-traceable-p' predicate.
(trace--read-args): Renamed to `trace--read-function-args'
(trace-function-foreground, trace-function-background): Call the
renamed `trace--read-function-args'.
(trace-is-traced, untrace-function, untrace-all): Doc updates/fixes.
* etc/NEWS: Mention the new trace commands.
* doc/misc/tramp.texi: Update "(tramp) Traces and Profiles" to use
`trace-package'.

I should note that I elected not to support foreground tracing for my proposed commands, simply because it seemed to me that foreground tracing could be problematic in too many cases, when the traces are being applied en masse on the basis of function name pattern matching. The current `trace-function-foreground' docstring says: > This function creates BUFFER if it does not exist. This buffer will > popup whenever FUNCTION is called. Do not use this function to trace > functions that switch buffers, or do any other display-oriented > stuff - use ‘trace-function-background’ instead. My compromise was to indicate the `trace-buffer' value in the echo area when the commands are invoked, so that the user would know where the trace output was happening. Actually popping up that buffer when the `trace-package' or `trace-regexp' command is used would be another (perhaps nicer) option? I'm open to recommendations for the most useful approach. Do others think that foreground versions of these commands would be a good idea? A prefix argument could mean "use foreground tracing", but that's inconsistent with `trace--read-args' which uses a prefix arg to prompt the user for the trace buffer and a context expression -- which I now realise is behaviour that my commands should incorporate as well. -Phil

Consistency is good, so some kind of change seemed sensible to me, but I don't especially mind one way or the other. If one of the maintainers wants to make a recommendation, I'll update the code (or leave it as-is) accordingly. -Phil

Yes, that's a good point. I'll add one to the next revision.
Something like this?
** Trace
*** New commands 'trace-package' and 'trace-regexp' (and their
counterparts 'untrace-package' and 'untrace-regexp') allow for the
bulk tracing of calls to functions with names matching a specified
prefix or regexp.
As there's no info node for trace.el, that could perhaps be a +++
entry; although a grep shows me that "(tramp) Traces and Profiles"
could be amended to change:
(require 'trace)
(dolist (elt (all-completions "tramp-" obarray 'functionp))
(trace-function-background (intern elt)))
to:
(trace-package "tramp-")
It would be good to add a node to the elisp manual covering trace.el,
but that's not strictly part of this patch.

Looking good. And I've wanted these commands both times I've had a need to use trace.el. This patch could probably use a NEWS entry, though. > (I note that the `trace-is-traced' function does not follow the usual > naming convention for predicates. Should this be renamed to > `trace-is-traced-p' ?) I'm not 100% sure about the protocol here, but including both "-is-" and "-p" in a function name seems too much. So maybe you should do the opposite and rename trace-is-traceable-p to trace-is-traceable.

trace.el currently only has commands for adding a trace to a single
function, and for untracing either a single function or ALL traced
functions.
This patch adds commands for tracing and untracing functions in bulk,
either by function name prefix (`trace-package' and `untrace-package')
or by regexp (`trace-regexp' and `untrace-regexp').
The use of the term "package" for the prefix-based commands was chosen
for consistency with `elp-instrument-package', from which this code is
partly derived, and from which I have also maintained a warning and
basic protection against attempts to trace too many functions at once
(which can indeed render Emacs unusable). It it still possible to do
this, but I feel the checks which are currently in place are probably
sufficient to protect against accidents.
`trace-is-traceable-p' is using Stefan's suggestion in his comment on
my initial implementation at https://stackoverflow.com/a/44241058 and
I have changed the completing-read filter predicate in
`trace--read-args' to also use this (instead of `fboundp'), on the
assumption that this makes more sense.
(I note that the `trace-is-traced' function does not follow the usual
naming convention for predicates. Should this be renamed to
`trace-is-traced-p' ?)
This patch also removes some outdated docstring comments for
`untrace-function' which were clearly remnants of the earlier
implementation using advice.el (whereas the current library is based
on nadvice.el).
