Not yet. <!-- et de toute façon GDL est pour l'instant équivalent à la version

Is there on-line help for SAXO ?

</question>
<answer>
<para>
Yes, if you use at least IDL 6.2. It is produced by <application><ulink url="http://www.ittvis.com/codebank/search.asp?FID=100">IDLdoc</ulink></application>. SAXO and IDL online_help have been merged, you can simply get the help by typing:
     <screen>
       <prompt>&promptidl;</prompt> <userinput><command>?</command></userinput>
     </screen>

Is there an SAXO Style Guide available ?
</para>
</question>
<answer>
<para>
There is a template for header <ulink url="../new_header.txt">new_header.txt</ulink>
which can be parsed by <application>IDLdoc</application>.
</para>
<para>
This file can be added in <application>Emacs</application> configuration
<menuchoice>
  <shortcut>
    <keycombo><keysym>C-c</keysym><keysym>C-h</keysym></keycombo>
  </shortcut>
  <guimenu>IDLWAVE</guimenu>
  <guimenuitem>Templates</guimenuitem>
  <guimenuitem>Doc Header</guimenuitem>
</menuchoice>.
in your <filename>${HOME}/.emacs</filename> like this :
<programlisting>
(add-hook 'idlwave-mode-hook
  (function
    (lambda ()
     (setq idlwave-file-header '("<replaceable>SAXO_basedirectory</replaceable>/SAXO_DIR/SRC/Documentation/new_header.txt")
    ))))

<question>
<para>
Is there any trouble with <application>IDLdoc</application> ?
</para>
</question>
<answer>
<para>
Yes, there are some :
<itemizedlist>
<listitem>
<para>
<literal>\</literal> in <filename>*.pro</filename> are not written
in <filename>*.html</filename>.
They must be escaped by an other <literal>\</literal> or you can choose an other character.
</para>
</listitem>
<listitem>
<para>
<guimenu>Search</guimenu> doesn't handle characters like <literal>-</literal>
and <literal>|</literal>.
</para>
</listitem>
<listitem>
<para>
Paragraphs of <filename>*.pro</filename> headers are shown with a proportional
font in the <literal>HTML</literal> release.
</para>
<para>
If you need to draw some small figure like grid cell, you can encapsulate
the block to be shown in constant font <!-- see savesaxo.sh -->
between
<literal>; &lt;fixe&gt;</literal> and
<literal>; &lt;/fixe&gt;</literal>
</para>
</listitem>
</itemizedlist>
</para>
<para>
Unfortunately, these troubles may not be fixed because the author does not
have anymore the opportunity to work on his own work.

<para>
Bugs can be submitted to IDL but we do not expect answers !

<question>
<para>
How can I check spelling of XML files ?
</para>
</question>
<answer>
<para>
There is one way with command line :
     <screen>
       <prompt>$</prompt> <userinput><command>aspell</command> <option>--mode=sgml</option> <option>-c</option> <parameter><filename><replaceable>xmlfile</replaceable></filename></parameter></userinput>
     </screen>
</para>
</answer>
</qandaentry>
<qandaentry>
<question>
<para>
How can I check spelling of IDL files ?
</para>
</question>
<answer>
<para>
Not so easy but you can start with something like this :
     <screen>
       <prompt>$</prompt> <userinput><command>cd</command> <parameter><envar>${HOME}</envar>/SAXO_DIR/SRC</parameter></userinput>
       <prompt>$</prompt> <userinput>list=$(find . -name "*.pro")</userinput>
       <prompt>$</prompt> <userinput>for file in ${list}; do aspell list &lt; ${file}; done > /tmp/list_word </userinput>
       <prompt>$</prompt> <userinput>sort -u /tmp/list_word > /tmp/list_sort</userinput>
     </screen>
</para>
<para>
This will give <filename>/tmp/list_sort</filename> a list of sorted word
used in IDL files that are not in the default dictionnary.
Some of these words are correct in IDL and SAXO vocabulary, so they do not have to be replaced but some typo can be found.
</para>
<para>
To find occurences of one of these misspelled words, you have to do this :
     <screen>
       <prompt>$</prompt> <userinput>find . -name "*.pro" -exec grep -h "<replaceable>misspelled_word</replaceable>" {} \;</userinput>
     </screen>
</para>
<para>
We should improve this by providing some IDL and SAXO dictionnary. <!-- ++ -->
</para>

<question>
<para>
How can I see online help update ?
</para>
</question>
<answer>
<para>
You won't see  online help update if you are working with the official distribution because of <varname>!HELP_PATH</varname>. To override this problem, when you are in <filename class="directory"><replaceable>SAXO_basedirectory</replaceable>/SAXO_DIR/SRC/Documentation/xmldoc/</filename>,  you can call online help like this :
     <screen>
       <prompt>&promptidl;</prompt> <userinput><command>ONLINE_HELP</command>,<option>book="../idldoc_assistant_output/idldoc-lib.adp"</option></userinput>
     </screen>
</para>
</answer>
