<p>EvMore - pager mechanism</p>
<p>This is a pager for displaying long texts and allows stepping up and down in
the text (the name comes from the traditional ‘more’ unix command).</p>
<p>To use, simply pass the text through the EvMore object:</p>
<p>The <strong>always_page</strong> argument decides if the pager is used also if the text is not long
enough to need to scroll, <strong>session</strong> is used to determine which session to relay
to and <strong>justify_kwargs</strong> are kwargs to pass to utils.utils.justify in order to
change the formatting of the text. The remaining <strong>**kwargs</strong> will be passed on to
the <strong>caller.msg()</strong> construct every time the page is updated.</p>

<dlclass="field-list simple">
<dtclass="field-odd">Parameters</dt>
<ddclass="field-odd"><ulclass="simple">
<li><p><strong>caller</strong> (<em>Object</em><em> or </em><em>Account</em>) – Entity reading the text.</p></li>
<li><p><strong>inp</strong> (<em>str</em><em>, </em><aclass="reference internal"href="evennia.utils.evtable.html#evennia.utils.evtable.EvTable"title="evennia.utils.evtable.EvTable"><em>EvTable</em></a><em>, </em><em>Paginator</em><em> or </em><em>iterator</em>) –<p>The text or data to put under paging.</p>
<ul>
<li><p>If a string, paginage normally. If this text contains
one or more <strong>\f</strong> format symbol, automatic pagination and justification
are force-disabled and page-breaks will only happen after each <strong>\f</strong>.</p></li>
<li><p>If <strong>EvTable</strong>, the EvTable will be paginated with the same
setting on each page if it is too long. The table
decorations will be considered in the size of the page.</p></li>
<li><p>Otherwise <strong>inp</strong> is converted to an iterator, where each step is
expected to be a line in the final display. Each line
will be run through <strong>iter_callable</strong>.</p></li>
</ul>
</p></li>
<li><p><strong>always_page</strong> (<em>bool</em><em>, </em><em>optional</em>) – If <strong>False</strong>, the
pager will only kick in if <strong>inp</strong> is too big
to fit the screen.</p></li>
<li><p><strong>session</strong> (<aclass="reference internal"href="evennia.server.session.html#evennia.server.session.Session"title="evennia.server.session.Session"><em>Session</em></a><em>, </em><em>optional</em>) – If given, this session will be used
to determine the screen width and will receive all output.</p></li>
<li><p><strong>justify</strong> (<em>bool</em><em>, </em><em>optional</em>) – If set, auto-justify long lines. This must be turned
off for fixed-width or formatted output, like tables. It’s force-disabled
if <strong>inp</strong> is an EvTable.</p></li>
<li><p><strong>justify_kwargs</strong> (<em>dict</em><em>, </em><em>optional</em>) – Keywords for the justify function. Used only
if <strong>justify</strong> is True. If this is not set, default arguments will be used.</p></li>
<li><p><strong>exit_on_lastpage</strong> (<em>bool</em><em>, </em><em>optional</em>) – If reaching the last page without the
page being completely filled, exit pager immediately. If unset,
another move forward is required to exit. If set, the pager
exit message will not be shown.</p></li>
<li><p><strong>exit_cmd</strong> (<em>str</em><em>, </em><em>optional</em>) – If given, this command-string will be executed on
the caller when the more page exits. Note that this will be using whatever
cmdset the user had <em>before</em> the evmore pager was activated (so none of
the evmore commands will be available when this is run).</p></li>
<li><p><strong>kwargs</strong> (<em>any</em><em>, </em><em>optional</em>) –<p>These will be passed on to the <strong>caller.msg</strong> method. Notably,
one can pass additional outputfuncs this way. There is one special kwarg:
- text_kwargs - extra kwargs to pass with the text outputfunc, e.g.</p>
<blockquote>
<div><p><strong>text_kwargs={“type”: “help”} would result to each page being sent
to **msg</strong> as <strong>text=(pagetxt, {“type”: “help”})</strong>.</p>

<dlclass="field-list simple">
<dtclass="field-odd">Parameters</dt>
<ddclass="field-odd"><ulclass="simple">
<li><p><strong>caller</strong> (<em>Object</em><em> or </em><em>Account</em>) – Entity reading the text.</p></li>
<li><p><strong>inp</strong> (<em>str</em><em>, </em><aclass="reference internal"href="evennia.utils.evtable.html#evennia.utils.evtable.EvTable"title="evennia.utils.evtable.EvTable"><em>EvTable</em></a><em>, </em><em>Paginator</em><em> or </em><em>iterator</em>) –<p>The text or data to put under paging.</p>
<ul>
<li><p>If a string, paginage normally. If this text contains
one or more <strong>\f</strong> format symbol, automatic pagination and justification
are force-disabled and page-breaks will only happen after each <strong>\f</strong>.</p></li>
<li><p>If <strong>EvTable</strong>, the EvTable will be paginated with the same
setting on each page if it is too long. The table
decorations will be considered in the size of the page.</p></li>
<li><p>Otherwise <strong>inp</strong> is converted to an iterator, where each step is
expected to be a line in the final display. Each line
will be run through <strong>iter_callable</strong>.</p></li>
</ul>
</p></li>
<li><p><strong>always_page</strong> (<em>bool</em><em>, </em><em>optional</em>) – If <strong>False</strong>, the
pager will only kick in if <strong>inp</strong> is too big
to fit the screen.</p></li>
<li><p><strong>session</strong> (<aclass="reference internal"href="evennia.server.session.html#evennia.server.session.Session"title="evennia.server.session.Session"><em>Session</em></a><em>, </em><em>optional</em>) – If given, this session will be used
to determine the screen width and will receive all output.</p></li>
<li><p><strong>justify</strong> (<em>bool</em><em>, </em><em>optional</em>) – If set, auto-justify long lines. This must be turned
off for fixed-width or formatted output, like tables. It’s force-disabled
if <strong>inp</strong> is an EvTable.</p></li>
<li><p><strong>justify_kwargs</strong> (<em>dict</em><em>, </em><em>optional</em>) – Keywords for the justify function. Used only
if <strong>justify</strong> is True. If this is not set, default arguments will be used.</p></li>
<li><p><strong>exit_on_lastpage</strong> (<em>bool</em><em>, </em><em>optional</em>) – If reaching the last page without the
page being completely filled, exit pager immediately. If unset,
another move forward is required to exit. If set, the pager
exit message will not be shown.</p></li>
<li><p><strong>exit_cmd</strong> (<em>str</em><em>, </em><em>optional</em>) – If given, this command-string will be executed on
the caller when the more page exits. Note that this will be using whatever
cmdset the user had <em>before</em> the evmore pager was activated (so none of
the evmore commands will be available when this is run).</p></li>
<li><p><strong>kwargs</strong> (<em>any</em><em>, </em><em>optional</em>) –<p>These will be passed on to the <strong>caller.msg</strong> method. Notably,
one can pass additional outputfuncs this way. There is one special kwarg:
- text_kwargs - extra kwargs to pass with the text outputfunc, e.g.</p>
<blockquote>
<div><p><strong>text_kwargs={“type”: “help”} would result to each page being sent
to **msg</strong> as <strong>text=(pagetxt, {“type”: “help”})</strong>.</p>
