squirrel_export.awk producing "empty" files

[evilstreak]

I tried to add a new method into the AI API (AITown.IsCity, which returns the value of town.larger_town), ran ./squirrel_export.sh (whilst in the src/ai/api/ directory) and it produced almost empty files in all cases (except for ai_controller.hpp.sq which the script skips).

The actual contents look like this:

Code: Select all

$ cat ai_town.hpp.sq 
/* $Id$ */
/* THIS FILE IS AUTO-GENERATED; PLEASE DO NOT ALTER MANUALLY */

#include "*/"

When I manually run the awk script against a single file I get the same output as above (i.e. the problem is in the awk script, not in the shell script, though I think there is an unrelated error in the shell script that I'll try to provide a patch for).

This is on Mac OS X 10.5.7 and awk is version 20040207

There are many flavours of 'awk'. Probably you don't have a flavour that supports everything we use.

Not much I can do about because I don't have Mac OS X (nor a Mac) or your version, don't even have a clue what flavour of 'awk' it is.

Using gawk (easily installed via MacPorts) did the trick.

I've made it more clear that squirrel_export needs gawk; it seems to be the only flavour of awk that actually supports everything we want to do.
