Controlling execution of auto-transacations

[Craig Earls]

John recently pointed out the auto xact are O(n) where are the number of transactions   I happen to have eleven, 9 of which are only useful when running one particular report (asset allocation).  Is there a way to specify values on the command line which could turn certain auto-xacts on or off?  I am thinking of two possibities:

1.  set a value on the command line that would be available for use in value expression and hence the expr of the auto-xact.  This doesn't really turn them OFF, just allows more flexibility

2.  Something similar to the C preprocessor #IFDEF structure where a block of input could be incorporated, or not, based on command line values.

Hi,

Craig, I believe your suggestion could solve my "a few minutes ago" post about side effect of recent commit about automated transactions. Let's John give his views.

This would be trivial to add, actually, but it would still result in
evaluating a value expression for every posting -- to test that provided
value. But it wouldn't evaluate as much of the expression each time.

Um, eww. :) But if that would really help people, something like an #ifdef
using value expressions would actually be quite easy.

ledger seems to accept multiple --file arguments, so you could move the
asset-allocation transactions to a separate file and include it only
when running that report. Or you could use one file that sets up the
auto-transactions and pulls in your data with an 'include' command.

I never tried multiple --file arguments.  That might be the best wat to implement idea 2.
