[GRASS-dev] still problems with overwrite in scripts

[Michael Barton]

Thanks, but neither are relevant (or work) in my case. See below.

I don't want a pull down list of existing files. I just want a string option so that users can enter a prefix to create 3 output files. 

So %# type: string. 

Of course this does not automatically add the overwrite flag

My question was about testing for the overwrite flag. But I did try this, as I mentioned in my post to Glynn and get an error wherever I put it. I tried in the string option for output prefix first, of course. But when that didn't work, I tried in the input and pull-down for sharpening algorithm too. No luck anywhere. If it only works in an option specified by G_OPT_R_OUTPUT and G_OPT_V_OUTPUT automatically generates and overwrite flag box without adding it, it seems kind of redundant. Shrug.

I wrote a workaround using an -o flag. But if there is some other way to do this, let me know.

It will help when the g.parser docs are updated from the current BASH centric examples to use G_OPT_R_OUTPUT, G_OPT_V_OUTPUT, and other such function that currently only show up in the C part of the programmer's manual.
