Search and Insert new line and Increment if line is missing

Harry Harris

Hi All,
I am wanting to search all files with a specific name (texture.cfg - I know how to do this!). I then want to see if a specific line is in these files i.e. fallback.??=…\texture\Planes_Generic. If the line does NOT exist then we need to add the line and increment the fallback.?? by one from the previous line. However some of the files are formatted “differently”. A couple of examples are:

Example 1
[fltsim]

fallback.1=…\Asobo_208B_GRAND_CARAVAN_EX\texture
fallback.2=…\texture\AS1000
fallback.3=…\texture\Gauges
fallback.4=…\texture\AS700
fallback.5=…\texture\AS140
fallback.6=…\texture\Extinguisher
fallback.7=…\texture\Lights
fallback.8=…\texture\Glass
fallback.9=…\texture\DetailMap
fallback.10=…\texture

The next line needs to be:
fallback.11=…\texture\Planes_Generic

Example 2
[fltsim]

fallback.1=…\texture\AS1000
fallback.2=…\texture\Gauges
fallback.3=…\texture\AS700
fallback.4=…\texture
fallback.5=…\texture\AS140
fallback.6=…\texture\Extinguisher
fallback.7=…\texture\Lights
fallback.8=…\texture\Glass
fallback.9=…\texture\DetailMap
fallback.10=…\texture

fallback.11=…\Asobo_208B_GRAND_CARAVAN_EX\texture

The next line needs to be:
fallback.12=…\texture\Planes_Generic

Is this sort of thing possible?

TIA

@harry-harris ,

You aren’t going to be able to do that with a normal Replace or Find in Files dialog box. The “increment” is meaningless to a regular expression, and cannot be done.

There are examples in the forum of using the PythonScript plugin, and writing a script which will search the active file and do a “+1” replacement – search the forum for add_1 for examples of how to do that. There are also PythonScript examples of looping over a number of files in PythonScript plugin. Combine those two concepts into one script, and there you go.

Give it a try yourself; if you get stuck, show us what you’ve tried so far, and show how the results aren’t matching what you expect them to.

@peterjones Thank you for the pointers! Will try this today.

@harry-harris said in Search and Insert new line and Increment if line is missing:

fallback.??=…\texture\Planes_Generic

So you may need a bit of regular expression help here:

You want to search for a \ followed by a t but if you search for it the way you have written it you will not find that but rather you will be searching for a tab character as that is what the sequence \t means. You’ll want to use \\t instead.
You want to search for three . characters in a row, but . means something special to regular expressions. You’ll want to do \.\.\. or \.{3} instead. BUT SEE “LATE THOUGHT” BELOW.
To search for two digits in a row (where you have ??), you might want to do \d\d or \d{2}. ? is another special character to regular expressions.

Putting it all together, where you had said:

fallback.??=…\texture\Planes_Generic

You probably should do:

fallback\.\d\d=\.\.\.\\texture\\Planes_Generic

LATE THOUGHT:

Maybe from your data the three dots is really a Unicode ellipsis character. If that’s truly the case, maybe you can use it directly. It is hard to tell if it really is an ellipsis since you didn’t format your data appropriately when you posted, and the forum software may have manipulated it to be misleading.

If you want to revise your posting to make it less misleading, you can follow directions HERE.
