- use `#word` to concatenate, expand content with the resulting string
being treated as a word token. Can be used in dictionary or
primitive context.
In dictionary context, it fills the gap for constructing dictionary
names on-the-fly. For example,
```
#word "some_prefix_solverInfo_${application}"
{
type solverInfo;
libs (utilityFunctionObjects);
...
}
```
The '#word' directive will automatically squeeze out non-word
characters. In the block content form, it will also strip out
comments. This means that this type of content should also work:
```
#word {
some_prefix_solverInfo
/* Appended with application name (if defined) */
${application:+_} // Use '_' separator
${application} // The application
}
{
type solverInfo;
libs (utilityFunctionObjects);
...
}
```
This is admittedly quite ugly, but illustrates its capabilities.
- use `#message` to report expanded string content to stderr.
For example,
```
T
{
solver PBiCG;
preconditioner DILU;
tolerance 1e-10;
relTol 0;
#message "using solver: $solver"
}
```
Only reports on the master node.
