mlist to list DT_LNK elements

[eiro]

maildirs containing symlinks are good way to keep
track of some mails, some indexers [1] can use
this way to store the result of a query so you
can use maildir tools to do whatever you want
with the entries.

it would be convenient to use mblaze as well.

1: at least

• mu

  mu find -r --learlinks --format=links --linksdir=/tmp/s

• notmuch AFAIR

Note that mu find --fields l will just output the file name, then you can just use them as a sequence.
(That's how I use mairix.) (Also see contrib/msearch.)

If we're going to allow DT_LNK, code also needs changing in namescan and iterdir.

the thing is i see no reason to not support DT_LNK and there are plenty of possible usages.

(That's how I use mairix.) (Also see contrib/msearch.)

i would be curious about the reasons you chosen mairix. is there another channel to ask about it? (mailing list or something?)

If we're going to allow DT_LNK, code also needs changing in `namescan` and `iterdir`

if you like the idea, i would be happy to ammend the PR until it will please you. regards marc

Mostly because mairix was around long before mu, also it's indexes are way smaller (but it has other limitations.)

I can adapt the patch myself, thanks. I'll get around to it in the next few days.

thanks for this reply

ok. it's probably faster for you to edit your code than doing review. thanks a lot

i would had introduced something like #if defined(DT_REG) && defined(DT_LNK) && defined(DT_UNKNOWN) #define IS_LEGIT_DT(t) (t != DT_REG && t != DT_LNK && t != DT_UNKNOWN) #else #define IS_LEGIT_DT(t) (1) #endif in a file like config.h and then add some other generic macros and configuration like #if defined(__linux__) #define __GNU_SOURCE__ #endif #define uc ... #define lc ... regards marc
