<h2>Checking the Current Version</h2></a> |
| 24 |
+ |
The version of scram you are using can be found with the command<p> |
| 25 |
+ |
<pre> |
| 26 |
+ |
scram version |
| 27 |
+ |
</pre> |
| 28 |
+ |
<p> |
| 29 |
+ |
<a name=Download> |
| 30 |
+ |
<h2>Downloading Alternative SCRAM versions</h2></a> |
| 31 |
+ |
Once a version of SCRAM has been installed, downloading of other SCRAM versions |
| 32 |
+ |
becomes trivial with the <b>scram version</b> command. |
| 33 |
+ |
<br> |
| 34 |
+ |
If you supply a version number as an argument, SCRAM will check to see if the |
| 35 |
+ |
specified version is already installed. If it isn't then it will attempt to |
| 36 |
+ |
download the requested version automatically. |
| 37 |
+ |
<p> |
| 38 |
+ |
e.g. |
| 39 |
+ |
<pre> |
| 40 |
+ |
scram version V0_9_11 |
| 41 |
+ |
</pre> |
| 42 |
+ |
<p> |
| 43 |
+ |
<a name=Default> |
| 44 |
+ |
<h2>Making a version the default</h2></a> |
| 45 |
+ |
Running the <em>install_scram</em> script of a specific version |
| 46 |
+ |
(see <a href=install.html>Installation Guide</a>) |
| 47 |
+ |
will make that version the default.<p> |
| 48 |
+ |
<a name=Over> |
| 49 |
+ |
<h2>Overriding the default Version</h2></a> |
| 50 |
+ |
The default version can be overridden at any time by setting the |
| 51 |
+ |
<b>SCRAM_HOME</b> environmental variable to point to the top of the version |
| 52 |
+ |
required. It must be the full path to the version. |
| 53 |
+ |
<p> |
| 54 |
+ |
<a name=Auto> |
| 55 |
+ |
<h2>Automated Version Selection</h2></a> |
| 56 |
+ |
<em>(Version V0_9_40 and above)</em> |
| 57 |
+ |
Scram can be made to automatically select the correct version to use for a |
| 58 |
+ |
given project area, overridding any other version selection mechanism.<p> |
| 59 |
+ |
To turn this feature on, simply create the file <em>scram_version</em> |
| 60 |
+ |
(of your project development/release configuration directory) |
| 61 |
+ |
containing the required |
| 62 |
+ |
SCRAM version tag. Any scram command issued in that area then gets directed to |
| 63 |
+ |
the correct version if it is installed. |
| 64 |
+ |
<p> |
| 65 |
+ |
If the required version is not installed then a warning is issued, however |
| 66 |
+ |
execution of the command continues in the current version. |
