.TH general_interpreter_settings PL "02-JUN-2006 PL ploticus.sourceforge.net"
.SH General interpreter settings
The \fC#mode\fR directive can be used to make general
settings that affect how the QUISP template interpreter behaves.
.ig >>
<br><br><br>
.>>
.SH #mode
Set various operational modes.
.LP
Usage: \fC#mode \fIattribute\fR \fIvalue\fR
.LP
\fIattribute\fR may be one of the following:
.ig >>
<br><br>
.>>
.LP
\fBerror_mode\fR
.IP
Default is \fCstderr\fR, so that error messages are written to standard error.
This may be set to \fCstdout\fR for error messages to be written to standard output.
.ig >>
<br><br>
.>>
.LP
\fBdot_in_varnames\fR
.IP
Specifies whether variable names may contain periods (.).
Default is \fCyes\fR, which is convenient with SQL applications since join
results are named using a period.
.br
Example: \fC#mode dot_in_varnames no\fR
.ig >>
<br><br>
.>>
.LP
\fBevalvars\fR
.IP
Default is \fCyes\fR. Use \fCno\fR to turn off evaluation of variables.
.br
Example: \fC#mode evalvars no\fR
.ig >>
<br><br>
.>>
.LP
\fBnullrep\fR
.IP
This determines how NULL database fields will be represented.
Allowable values are \fCblank\fR, \fCnull\fR, \fCnbsp\fR, and \fCnoconvert\fR.
The default is \fCblank\fR which causes NULLs to be converted to zero length strings.
Use \fCnbsp\fR to convert NULLs to the HTML non-breaking space character \fC \fR
This should be invoked before result rows are fetched.
Conversion occurs after the row is retrieved from the database.
.nf
.fi
Example: \fC#mode nullrep nbsp\fR
.ig >>
<br><br>
.>>
.LP
\fBshellmetachars\fR
.IP
This specifies the set of characters that are to be screened out of
variables that are present when building a shell command
(see the opening paragraphs of the
.ig >>
<a href="shell.html">
.>>
\0#shell man page
.ig >>
</a>
.>>
). There should be no embedded whitespace.
This can also be set in the
.ig >>
<a href="config.html">
.>>
\0project config file
.ig >>
</a>
.>>
.br
Default set of shell metacharacters is: \fC"'`$\\;\fR
.br
Example: \fC#mode shellmetachars "'`\fR
.ig >>
<br><br><br>
