question regarding my emacs package

question regarding my emacs package

[ram]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

hi, i am a professional programmer, but this is my first time submitting an emacs package. i have conversed a little with stefan monnier, and i believe the package i have meets the requirements for elpa submission, but i am unsure as to the appropriate licensure. i took some inspiration from two packages: dogears and gumshoe, neither of which is in elpa. however, i did not use any code from here; i just wanted some inspiration regarding the feature set

it is unclear to me whether my package warrants inclusion in gnu or non gnu elpa, if at all, but i have certainly found it useful, despite its simplicity

here is the repo: https://github.com/gitrj95/breadcrumbs.el

best,
ram

That should not be an issue, these packages appear to only be a source
of inspiration?

Complexity is not a requirement for being useful :)

Here are a few suggestions:

changing the central type from defclass to cl-defstruct has appeared to cause bugs? i am not sure what to make of this, but find-file and its variants do not appear to work when changing only this. the file is not opened; it is not that the file is opened but the active buffer isn't switched

That might have been a typo on my end, I did not evaluate the code and
was is a hurry to send you the diff.  My point is that you don't need
defclass, unless I am missing something in your code (and I don't think
the minimal convenience of `with-slots' warrants classes here).

just got back to this. calling find-file appears to not open the new file when called through the code. i'm not immediately sure what the problem is. any tips? i'll look more into this tonight

The main things were inconsistent indentation, using mapcar for
side-effects (if anything mapc should be used in that case, but I think
dolist is the best choice) and there still was one checkdoc complaint.
On the topic of docstrings, I think you should invest some more time to
make them understandable to someone who doesn't already know what the
code is about.

Have you signed the FSF copyright assignment?

[snip]

I tried loading the file from github on emacs master and it fails when
trying to compile

```
(defun breadcrumbs--drop ()
  "Track the buffer position as a `breadcrumbs--breadcrumb'.

If this has already been tracked, move an existing one in `breadcrumbs-ring' to head."
  (let* ((breadcrumb (make-breadcrumbs--breadcrumb))
         (index (ring-member breadcrumbs-ring breadcrumb)))
```

with
```
Debugger entered--Lisp error: (wrong-type-argument stringp (buffer-file-name))
  make-breadcrumbs--breadcrumb--cmacro((make-breadcrumbs--breadcrumb))
  apply(make-breadcrumbs--breadcrumb--cmacro (make-breadcrumbs--breadcrumb) nil)
  macroexp--compiler-macro(make-breadcrumbs--breadcrumb--cmacro (make-breadcrumbs--breadcrumb))
```

The cl-defstruct slot has an initform "(buffer-file-name)" which seems
legit since it takes an optional argument.

However when I change the form to (buffer-file-name nil) as below, it
loads


```
(cl-defstruct breadcrumbs--breadcrumb
  (buffer-file-name
   (buffer-file-name nil)
   :documentation "The file backing the breadcrumb.")
```

Common Lisp has a problem with the interpretation of the lexical
scoping of the initforms. C-h f cl-defstruct doesn't impose any
conditions on the SDEFAULT form.  Are there any guarantees or
limitations on the forms that can go into SDEFAULT

Just a FYI, I've recently (about a month ago) created a package called
breadcrumb.el, singular. Lives at https://github.com/joaotavora/breadcrumb
and seems to be fairly popular.

Not saying anyone should consider changing package names, just dropping
this note here as a FYI.

Yes, but it is pretty close and will probably cause confusion.  That
being said, João is not part of any ELPA so one could argue the name
hasn't been reserved...

Just some thoughts:

1. There is no name clash, as ram observed

2. I'm not aware of a name reservation/parking procedure.  As far as I can
tell, ram's breadcrumbs.el isn't a part of any ELPA yet.

3. If early manifestation of adding a library is somehow relevant
then I might point you to this ~8-month old thread where I propose we
add breadcrumb.el to Emacs [1].  That's where breadcrumb.el was born and
proposed for Emacs.  I'm still on the fence about whether to propose
it for a :core package or ELPA package.  It takes inspiration on a
similar-named lsp-mode feature and the "breadcrumb" concept is apparently
a common name given to the type of feature breadcrumb.el enables.

4. There is no name clash, I think this bears repeating.

5. Above, I wrote "if early manifestation... is relevant".  I don't think
it should be.  If avoiding confusion to users is a goal to pursue -- and
if this confusion is indeed real (see 4 and 1) -- then I think it's more
important to evaluate the potential consequences of a rename in existing
users of each package.  We don't know that number, but merely as data point,
breadcrumbs.el has 6 github stars and breadcrumb.el has 116.

6. Please let's avoid another "meaning of names/meaning of life" thread.
There is no name clash.

Oh, I did not know that.  Intuitively, I would argue that you tried to
reserve the name in the "core emacs/ELPA namespace" first.

I think that both options would be fine, and I'd be happy to help with
either.

Arguing via stars is difficult, because on the one hand you are a well
known Elisp author and your packages are bound to attract more attention
over a longer period of time, but we cannot deduce anything from these
facts.  E.g. None of my packages (except for Compat, which is
co-maintained) are on GitHub, so this metric couldn't be used if ram
decided to use SourceHut as well.

Ok, in that case I won't argue that that this is one of the issue of
using intuitive names ;)

So with my emacs-30 nativecomp this just doesnt work. the
buffer-file-name slot of the cl-defstruct has to be changed to
buffer-file-name-1 (and the corresponding accessors to
breadcrumbs--breadcrumb-buffer-file-name-1) throughout the file.

Do others not see this limitation in the compiler?

Does it works on the same Emacs codebase without native compilation?

If a name clash existed, you wouldn't just have confusion,
you'd have an integration problem in your hands.

Of course we can.   We can infer from the amount of attention attracted
the number of users that have dispensed that attention.  The period
of time over which that amount of attention was gathered and notoriety
of the author is irrelevant: all other things being equal, you want to
know the number of users impacted at the time by some hypothetical
administrative decision.

What I'm trying to tell you is two things: 1. I do agree with you that
some confusion is bound to arise from the similarity in name, though
I'm not sure it warrants any action: that is up to you or others.  2. If
you wish to tackle the problem via some specific action, it's much smarter
to consider the number of users affected by that action rather than
considering who "reserved" the name first.

Yes, it looks like native-comp wont let you use buffer-file-name as a
cl-defstruct slot name if you also have an initializer (SDEFAULT)
form.  it gets confused and tries to use the elisp function
definition.

The following works on non-native comp but fails on native-comp.

```
(require 'cl-lib)
(defun xyz ())
(cl-defstruct barf
  (buffer-file-name (xyz)))

(defun barf-foo ()
  (let ((barf (make-barf)))))
```

What's the definition of fail here?

calling M-: (byte-compile-file <file> ) or M-: (native-compile <file>)
on a file with those forms puts me in the debugger backtrace buffer with
the sort of lines I posted upthread.

OK.  I see why others dont see a problem with this. If I call M-x
byte-compile-file or M-x emacs-lisp-native-compile-and-load I only see
this in *Messages* and nothing in *compile-log*

```
Compiling /home/madhu/elisp/debug/barf.el... (make-barf)
Warning: Optimization failure for make-barf: Handler: make-barf--cmacro
(wrong-type-argument stringp (xyz))
Compiling /home/madhu/elisp/debug/barf.el...done
Wrote /home/madhu/elisp/debug/barf.elc
```

So my "errors" were a result of debug-on-error being `t' when evaluating
lisp interactively. So i assume this is not a real problem.

terser is always welcomed. is there a cute analog for dropping breadcrumbs (ie tracking a buffer position in my package's parlance) for a trail?

==> Optimization failure for make-barf: Handler: make-barf--cmacro
(wrong-type-argument stringp (xyz))

Madhu, seems you have hit a corner case bug.

The resulting code (i.e. the defined `make-barf--cmacro') uses
`buffer-file-name' as the name of a variable it let-binds, which results
in the above warning (or a similar error message) in the case of this
variable.

Is this a known limitation (Mattias)?


TIA,

Michael.

Not to me until now. I'm sure Stefan would delight in delving into the nuts and bolts of the matter.

I think this is more or less the same as Bug#47552 ("cl-defstruct field
names matching read-only variables -> bad code") - which was marked as
fixed, but isn't.  I have reopened that one and added the recipe from
here as another incarnation example.

@ram: AFAIU you need to use a different slot name.  This one will cause
problems due to a bug in Emacs.

No, sorry.  In master using this example:

#+begin_src emacs-lisp
  (require 'cl-lib)
  (defun xyz ())
  
  (cl-defstruct barf "Doc" (buffer-file-name (xyz)))
  
  (defun barf-foo ()
    (let ((barf (make-barf)))
      barf))
#+end_src

I get an error when trying to load.  It compiles and I can load the
result, but for example M-: (make-barf :buffer-file-name t) errors.

Maybe there are differences due to lexical vs. dynamic binding and
changes to the compiler since 27.1, but I think the basic problem
remains the same.  If I were you I would avoid using 'buffer-file-name'
as slot name.

got around to this. new repo is here: https://github.com/gitrj95/trail.el

renamed from breadcrumbs to trail, as per joao's suggestion, and changed the semantics quite a bit. i had some questions:

-   i'm supporting "middle" truncation of the file path strings. i couldn't find this in emacs libs, but for this purpose, i found truncation at the suffix or prefix less useful than truncation in the middle. ie, i want to know the file name and extension almost always and the root directory (especially in a code context) almost always
-   i'm using markers to track relative positions instead of absolute positions. i found that, especially in the code context, i wanted the trail-mark to "know" that i've added code before it, but still point to the function prototype i marked before instead of sliding. markers don't seem to be persistable, so i had the absolute positions of the markers stored in the ring that can be persisted, but default to corresponding markers in an associated, private ring if those exist. on hook for buffer close, the absolute positions are updated with the marker details. this seems like a fairly common thing to want to do, so i'd hope that i didn't reinvent the wheel. again, i couldn't find anything

also:

-   checkdoc passes
-   tested on emacs 27, 28, and 29

let me know if you have any questions, and please send over the fsf copyright agreement when you have the chance

looking forward

There still appear to be a few minor issues.  Do you use Flymake?  If
not, try out M-x flymake-mode and it should highlight the byte-compiler
and checkdoc issues.  None of the issues appear to be blocking
inclusion though.

You have to request the copyright assignment form here on emacs-devel (I
