I'm rewriting a complicated construction where there's an equality
test on the length of the list of non matching elements, with a
simpler cl-some invocation.  The replacing code is self explanatory.

Isn't `seq-some' equivalent? (in this case, at least; cl-some is
willing to take more than one sequence).

This is only tangential to your question, but, unfortunately, we cannot
use `seq-some' as Org still supports Emacs 24.3.

OK. Note you can go even further: nested `if' should be replaced with
a `cond'.

Also, further nit: (not (cl-every ...)) will apply `not' only once.

In any case, it would be better if refactoring happens while introducing
unit tests *hint*.

Hi Nicolas, I think that the hint on testing is very correct, I'm afraid 
I changed the semantics of one of the original tests, and I found that 
there's other cl functions other than just cl-some, also cl-every, 
cl-notevery, and cl-notany.  I'll have a closer look at this.  and write 
some tests before changing the code.

I also looked for the strange idiom used here, and these two are the 
only two locations I found.

how do I run tests from the command line (I'm using make test) but then 
limited to one lisp file?  or one specific test?

ciao,

Mario

[-- Attachment #1: Type: text/plain, Size: 1344 bytes --]

second thought about testing:

if I did that, it would become longer than 15 lines, I would need 
refactoring quite a bit of stuff, and both things would require time, 
bureaucratic time, and programming time.

I had a closer look at my changes, re-read it, and used it a bit, and I 
think this is o.k.

see it yourself, when we have the agreement allowing you accept changes 
longer than 15 lines, I'll consider the needed refactoring and test-writing.

ciao,

Mario

Use BTEST_RE="regexp" prefix, e.g.,


  BTEST_RE="table" make test

I didn't know you hadn't signed FSF papers. Since we are in feature
freeze, and this is not a bug-fix, what about waiting until bureaucracy
is over? 

Of course, this assumes you're planning to sign FSF papers.

I'm fine with it, but I'm accumulating several adjustments, and it's 
being difficult to keep track of each of them separately.

I have signed and sent them in, 5th of June.

like … I'm adding a way to collect #+PLOT lines depending on which set 
of settings I want, to produce the graph.

#+PLOT[1]: set:"yrange [0:4200]"
#+PLOT[1]: set:"key at 33,4100 top left spacing 1.4"
#+PLOT[1]: set:"arrow from 59.5,0 rto 0,4200 nohead ls 1"
#+PLOT[2]: set:"yrange [50:10000]" set:"logscale y 10"
#+PLOT[2]: set:"key at 35,9000 top left spacing 1.4"
#+plot[2]: set:"arrow from 59.5,50 rto 0,200 nohead ls 1"
#+PLOT: set:"xtics rotate by 90" set:"mouse mouseformat ' '"
#+PLOT: ind:1 deps:(6 3 7 4 10) xticdep:15
#+plot: use:2
|  n |  data | prove, |  casi, | ratio |   prove, |    casi, | 7run | 
casi*6 |  casi, | cum-p | cum-c | cum-r |   ++% | lunes |
|    |       | valore | valore |       |    media |    media |      
|        | m.c.*5 |       |       |       |       | |

the #+plot: use:2 tells the program to collect PLOT[2] lines and to skip 
plot[1] definitions.

it needs be the first one met by the program, or at least precede any 
such lines.

oh, and the xticdep is an other addition

both I haven't shared yet, because it's a bit complicated doing so while 
the code doesn't contain the previous changes.

ciao, Mario

I don't think this is a good idea, really. For this kind of complexity,
I suggest to consider using gnuplot source code blocks, with the table
as input.
