- <h2 class="section">1.1 General Options</h2>
- <p>Regardless of whatever other command line parameters are given,
- <code>avram</code> accepts the following parameters:
- </p>
- <a name="index-help"></a>
- <a name="index-emulation"></a>
- <a name="index-help-command-line-option"></a>
- <a name="index-emulation-command-line-option"></a>
- <dl compact="compact">
- <dt> <code>-h, --help</code></dt>
- <dd><p>Show a summary of options and exit.
- </p></dd>
- <dt> <code>-V,-v, --version</code></dt>
- <dd><p>Show the version of program and a short copyleft message and exit.
- </p></dd>
- <dt> <code>--emulation=<var>version</var></code></dt>
- <dd><p>Be backward compatible with an older version of <code>avram</code>. This
- option should include a valid version number, for example
- <kbd>0.13.0</kbd>, which is the version of <code>avram</code> to be
- emulated. It can make virtual code applications future proof, assuming
- that future versions of <code>avram</code> correctly support backward
- compatibility. It may be used in conjunction with any other option in
- any mode of operation.
- <a name="index-web-page"></a>
- <a name="index-home-page"></a>
- <a name="index-url"></a>
- This copy of the user manual has not been updated since version 0.13.0 of
- <code>avram</code>, so it is unable to document incompatibilities with later
- versions. The latest version of the manual may be found at
- <a href="http://www.lsbu.ac.uk/~fureyd/avram">http://www.lsbu.ac.uk/~fureyd/avram</a>.
- </p></dd>
- <dt> <code>-e, --external-libraries</code></dt>
- <dd><a name="index-external_002dlibraries"></a>
- <p>Show a list of libraries with which <code>avram</code> has been linked and
- whose functions therefore could be called from virtual machine
- programs. This growing list currently includes selected functions from
- <code>fftw</code>, <code>glpk</code>, <code>gsl</code>, <code>kinsol</code>, <code>lapack</code>,
- <code>minpack</code>, <code>mpfr</code>, <code>lpsolve</code>, <code>Rmath</code> and <code>ufsparse</code>
- (see <a href="Preface.html#Preface">Preface</a>) which are documented further in <a href="External-Libraries.html#External-Libraries">External Libraries</a>.
- </p></dd>
- <dt> <code>-j, --jail</code></dt>
- <dd><a name="index-jail"></a>
- <p>This option disables execution of shell commands by virtual code
- applications, which is normally possible by default even for nominally
- non-interactive applications (see <a href="Parameter-Mode-Options.html#Parameter-Mode-Options">Parameter Mode Options</a>). A
- virtual code application attempting to spawn a shell (using the
- <code>interact</code> combinator) when this option is selected will
- encounter an exception rather than successful completion of the
- operation. This option is provided as a security feature for running
- untrusted code (see <a href="Security.html#Security">Security</a>), and is incompatible with
- ‘<samp>-i</samp>’, ‘<samp>-t</samp>’, and ‘<samp>-s</samp>’.
- </p></dd>
- <dt> <code>-f, --force-text-input</code></dt>
- <dd><a name="index-force_002dtext_002dinput-command-line-option"></a>
- <p>Normally <code>avram</code> will try to guess by looking at a file whether it
- is an ordinary text file or one that has been written in the virtual
- code file format, and choose a different internal representation
- accordingly. An application may require one representation or the
- other. This option tells <code>avram</code> to treat all input files other
- than the virtual code file (named in the first command line parameter)
- as text files regardless of whether or not it would be possible to
- interpret them otherwise. This option may be used in combination with
- any other option.
