RE: RE: [Infrastructures] new parser for Isconf

So I deleted the echo-$(IPx) lines.  Next:

I've got a chicken and egg problem: if types.ok isn't there, ischeck
insists it be retrieved from CVS.  If it is there, it dies:
"oracle_8.1.7.3_server is an invalid variable name.".  I suppose I'll
hand edit the types.ok file, then generate the checksum by nefarious use
of perl -d, but it shouldn't be like this...

Found it: a trailing tab on the dependency line.

I did change some targets, replacing "." with "_".

Next problem:

$ perl -I../lib/perl5 ../bin/ischeck
Checking hosts...up to date.
Checking types...
using Isconf::Parse
types:233: parse error

The trouble spot is:

   219
   220  oracle_cluster_1: oracle_8_1_7_3_server vcs_cluster
   221          CLUSTER_MEMBERS="mullet mackerel"
   222          CLUSTERID=1
...
   232          filesets/add__cluster-oracle1
   233          echo-$(IP1)
   234          echo-$(IP2)
   235

Those are the only two uses of $(var) in the types file, and they appear
cosmetic, so just remove them?

Thanks for explaining.  I'm now using:

bezukhov: sunos_base

Next: I'm using the types file from your CVS.  In vi, I just did

:%/^[^#]*:/s/	/ /g

i.e., on any [uncommented] target line [...] containing a colon, turn
all tabs into spaces. Now I get:

$ perl -I../lib/perl5 ../bin/ischeck
Checking hosts...up to date.
Checking types...
using Isconf::Parse
types:164: parse error

Annotated using vi's :set nu, that appears in

   161
   162  cognos_server: sun_server
   163          cognos_service_user
   164          pkg/add__java__1.4.1
   165

That happens to be the first pkg/ line containing a ".", and you said
there were new restrictions on the use of "." and "-".  I suppose I'm
going to have to read the grammar. But if you could post an example of a
grammatically correct types file, it would help.  Thanks,

    - Stephen

Yeah, change the tabs to spaces.

I couldn't find a good way to do this using the new parser, so now
spaces are ignored on a given line (i.e., you can have as many as you
like) but tabs should only ever occur at the beginning of a line,
signaling indentation.

If you'd like to look at the grammar and lexer and figure a way around
that, fine, but I figured it was a worthy sacrifice for the extra speed,
and actually makes more sense, anyway.  More restrictive, but more
consistent.
