Brackets & Such in formulae

[dec]

both '(' and '[' brackets seem highlt problematic ie very buggy when used in Convert or Actions

some really really illogical and inconsistent behaviour/results

i just gave up trying to fine-tune  it - i will just externally massage results later

%_filename%  ($if2(%album%,%album%) $if(%track%,Track $num(%track%,2),)) ($if2(%_date%,$right(%_date%,4))) ($if2(%_bitrate%,(%_bitrate%)) kbits) ($if2(%_length%, (%_length% min)))$if2(%_acoustid_id%, %_acoustid_id%)

just all sorts of buggy behaviour trying to insert text brackets of any sort WITHIN the formula

the other problem is that the doco does not consistently or logically list which 'placeholders' use underscores (as well as %!)

rhe doco is just pretty pathetically limited and lacks details

just a mess

Use the %Char macro to define reserved characters

[dec]

hi.

so where is a list of 'reserved characters'?

and surely it cannot include every type of bracket?

and it still would make sense as in practice it sort of HALF works ie i get ONE bracket, but not a pair

i get brackets that work outside the $if, but not inside (which is pretty useless, although i can fix afterwards with a different app)

%,() are reserved characters

Sure, because () defines arguments for a function.
P.S. $if is not our macro definition

1. ... and that is documrented where?

2.  square brackets [] seem to be a problem too

3. there is all sorts of inconsistent behaviour; but i would have to capture examples next time

[Artem]

and that is documrented where?

No, because its so trivial

square brackets [] seem to be a problem too

Provide an example

[dec]

characters, that would often be used in text strings and text formatting, that cannot be used (without error) "trivial", huh?

really?

[dec]

... will try to replicate what happened when i trying to create file name with content & format i wanted

[Artem]

really?

Yes if you using conditions macro, is not it? Do you see what characters are used to define macro in legend? Didn't that lead to the idea that key characters might be reserved?

[Artem]

... will try to replicate what happened when i trying to create file name with content & format i wanted

What format you wanted? Expression that you list in first post written using someone else's (not our) macro language, so what why it does not work in AIMP

[dec]

i think you are partially right.

maybe i mixing up AIMP probs with MP3Tag probs

i will have to go back and check which is which

:-(
