<h1>Configuration Environment</h2></a>
|
| 21 |
Each development area has associated with it an environment which is related to
|
| 22 |
the requirments of the configuration. The required environmnet can seen
|
| 23 |
using the
|
| 24 |
<p>
|
| 25 |
<em>
|
| 26 |
scram runtime [-csh|-sh]
|
| 27 |
</em>
|
| 28 |
<p>
|
| 29 |
command. Running the command as is will print the commands to the standard
|
| 30 |
output in either the csh or sh flavours. Note that it will not actually
|
| 31 |
run the commands - just print them. See scram runtime help for some examples
|
| 32 |
of using this command.
|
| 33 |
<p>
|
| 34 |
All variables that are set also have an associated SCRAMRT_xxx variable. This
|
| 35 |
allows scram to undo changes to the environment. This allows you, for example,
|
| 36 |
to switch between project environments without the two interfering. This
|
| 37 |
consistency checking is done automatically.

<h1>Application Environments</h1>
|
| 41 |
<ul>
|
| 42 |
An application may have environmental requirements in addition to the general
|
| 43 |
configuration described above. The runtime mechanism supports
|
| 44 |
this through the use of the <Runtime> tag.
|
| 45 |
<p>
|
| 46 |
Note that this means the Configuration Environment descriped above needs to
|
| 47 |
be set in addition.
|
| 48 |
<li><h2>Setting an application environment</h2>
|
| 49 |
<pre>
|
| 50 |
scram runtime [-csh|-sh] runtimefile
|
| 51 |
</pre>
|
| 52 |
The file runtimefile is searched for in the following order :
|
| 53 |
<ol>
|
| 54 |
<li>filename relative to current directory
|
| 55 |
<li>filename relative to local_area/src
|
| 56 |
<li>filename relative to release_area/src
|
| 57 |
<li>location of a BuildFile relative to local_area/src
|
| 58 |
<li>location of a BuildFile relative to release_area/src
|
| 59 |
</ol>
|
| 60 |
<li><h2>Information on Runtime Variables</h2>
|
| 61 |
<p>
|
| 62 |
<em>
|
| 63 |
scram runtime info runtimefile [variable]
|
| 64 |
</em>
|
| 65 |
<p>
|
| 66 |
Will print out any help available to describe the variables in the file
|
| 67 |
The optional variable will restrict the output to the specified variable.
|
| 68 |
|
| 69 |
<li><h2>Constructing a Runtime Environment File</h2>
|
| 70 |
An environmental variable in the runtime is indicated by
|
| 71 |
<p>
|
| 72 |
<font color=green>
|
| 73 |
<Runtime name=<em>VARIABLE</em> value=<em>value1</em> [type=path]><br>
|
| 74 |
Descriptive text of the variable - provides help to the users!<br>
|
| 75 |
</Runtime>
|
| 76 |
</font><p>
|
| 77 |
Groups are not yet supported by the runtime mechanism.
