<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 |

+ |
<li>location of a BuildFile relative to release_area/src |

<li><h2>Information on Runtime Variables</h2> |
| 61 |

<p> |
| 62 |

<em> |

+ |
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. |
