<title>Creating New Files</title>
<para><guimenu>File</guimenu>><guimenuitem>New</guimenuitem>
(shortcut: <keycap>C+n</keycap>) opens a new, empty, buffer. Another way
to create a new file is to specify a non-existent file name when
starting jEdit on the command line. A new file will be created on disk
when the buffer is saved for the first time.</para>

<section id="opening">
<title>Opening Files</title>
<para><guimenu>File</guimenu>><guimenuitem>Open</guimenuitem>
(shortcut: <keycap>C+o</keycap>) displays a file system browser dialog
box and loads the specified file into a new buffer.</para>
<para>Multiple files can be opened at once by holding down
<keycap>Control</keycap> while clicking on them in the file system
browser. The file system browser supports auto-completion; typing the
first few characters of a listed file name will select the file.</para>
<para>More advanced features of the file system browser are described in
<xref linkend="vfs-browser" />.</para>
<para>The <guimenu>File</guimenu>><guimenuitem>Recent
Files</guimenuitem> menu lists recently viewed files. When a recent file
is opened, the caret is automatically moved to its previous location in
that file. The number of recent files to remember can be changed and
caret position saving can be disabled in the
<guibutton>General</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box; see <xref
linkend="general-pane" />.</para>
<para>The <guimenu>Utilities</guimenu>><guimenuitem>Current
Directory</guimenuitem> menu lists all files and directories in the
current buffer's directory. Selecting a file opens it in a buffer for
editing; selecting a directory opens it in the file system browser (see
<xref linkend="vfs-browser" />).</para>
<note>
<para>Files that you do not have write access to are opened in
read-only mode, where editing is not permitted.</para>
</note>
<tip>
<para>jEdit supports transparent editing of GZipped files; if a file
begins with the GZip <quote>magic number</quote>, it is
automatically decompressed before loading and compressed when
saving. To compress an existing file, you need to change a setting
in the <guimenu>Utilities</guimenu>><guimenuitem>Buffer
Options</guimenuitem> dialog box; see <xref linkend="buffer-opts" />
for details.</para>

<title>Saving Files</title>
<para>Changed made in a buffer do not affect the file on disk until the
buffer is <firstterm>saved</firstterm>.</para>
<para><guimenu>File</guimenu>><guimenuitem>Save</guimenuitem>
(shortcut: <keycap>C+s</keycap>) saves the current buffer to
disk.</para>
<para><guimenu>File</guimenu>><guimenuitem>Save As</guimenuitem>
renames the buffer and saves it in a new location. Note that using this
command to save over another open buffer will close the other buffer, to
stop two buffers from being able to share the same path name.</para>
<para><guimenu>File</guimenu>><guimenuitem>Save a Copy
As</guimenuitem> saves the buffer to a different location but does not
rename the buffer, and does not clear the
<quote>modified</quote> flag. Note that using this command to save over
another open buffer will automatically reload the other buffer.</para>
<para><guimenu>File</guimenu>><guimenuitem>Save All</guimenuitem>
(shortcut: <keycap>C+e C+s</keycap>) saves all open buffers to disk,
asking for confirmation first. The confirmation dialog can be disabled
in the <guilabel>General</guilabel> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box.</para>
<section>
<title>Two-Stage Save</title>
<para>To prevent data loss in the unlikely case that jEdit should
crash in the middle of saving a file, files are first saved to a
temporary file in the same directory named
<filename>#<replaceable>filename</replaceable>#save#</filename>. If
this operation is successful, the original file is replaced with the
temporary file.</para>
<para>However, in some situations, this behavior is undesirable. For
example, on Unix this creates a new i-node so while jEdit retains
file permissions, the owner and group of the file are reset, and if
it is a hard link the link is broken. The <quote>two-stage
save</quote> feature can be disabled in the
<guibutton>General</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box; see <xref
linkend="general-pane" />.</para>
</section>
<section id="autosave">
<title>Autosave and Crash Recovery</title>
<para>The autosave feature protects your work from computer crashes
and such. Every 30 seconds, all buffers with unsaved changes are
written out, with their respective file names,
enclosed in hash (<quote>#</quote>) characters. For example,
<filename>/home/user/project/program.c</filename> will be autosaved to
<filename>home/user/project/#program.c#</filename>. </para>
<para> If you wish autosave files to be stored in an alternate
location, you can specify the <guilabel>Autosave Directory</guilabel>
as a <guilabel>Saving and Backup</guilabel> option. </para>
<para>Saving a buffer using one of the commands in the previous
section automatically deletes the autosave file, so they will only
ever be visible in the unlikely event of a jEdit (or operating
system) crash.</para>
<para>If an autosave file is found while a buffer is being loaded,
jEdit will offer to recover the autosaved data.</para>
<para>If <guilabel>Autosave of Untitled Buffers</guilabel> is enabled,
then jEdit will allow you to exit without asking you to save dirty untitled
buffers, and will silently restore them for you on next jEdit startup. </para>
<para>The autosave interval can be changed in the
<guibutton>Autosave and Backup</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box; see <xref
linkend="saving-backup-pane" />.</para>
</section>
<section id="backups">
<title>Backups</title>
<para>The backup feature can be used to roll back to the previous
version of a file after changes were made. When a buffer is saved
for the first time after being opened, its original contents are
<quote>backed up</quote> under a different file name.</para>
<para>The behavior of the backup feature is specified in the
<guibutton>Saving and Backup</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Global Options</guimenuitem>
see <xref linkend="saving-backup-pane" />.</para>
<para>The default behavior is to back up the original contents to
the buffer's file name suffixed with a tilde (~ ). For
example, a file named <filename>paper.tex</filename> is backed up to
<filename>paper.tex~</filename>.</para>
<itemizedlist>
<listitem>
<para>The <guilabel>Max number of backups</guilabel> setting
determines the number of backups to save. Setting this to
zero disables the backup feature. Settings this to more than
one adds numbered suffixes to file names. By default only
one backup is saved.</para>
</listitem>
<listitem>
<para>If the <guilabel>Backup directory</guilabel> setting
is non-empty, backups are saved in that location (with the
full path to the original file under it). Otherwise,
they are saved in the same directory as the original file.</para>
</listitem>
<listitem>
<para>The <guilabel>Backup filename prefix</guilabel>
setting is the prefix that is added to the backed-up file
name. This is empty by default.</para>
</listitem>
<listitem>
<para>The <guilabel>Backup filename suffix</guilabel>
setting is the suffix that is added to the backed-up file
name. This is <quote>~</quote> by default.</para>
</listitem>
<listitem>
<para>The <guilabel>Backup on every save</guilabel> option
is off by default, which results in a backup only being
created the first time a buffer is saved in an editing
session. If switched on, backups are created every time a
buffer is saved.</para>

<section id="line-separators">
<title>Line Separators</title>
<para>Unix systems use newlines (<literal>\n</literal>) to mark line
endings in text files. The MacOS uses carriage-returns
(<literal>\r</literal>). Windows uses a carriage-return followed by a
newline (<literal>\r\n</literal>). jEdit can read and write files in all
three formats.</para>
<para>The line separator used by the in-memory representation of file
contents is always the newline character. When a file is being loaded,
the line separator used in the file on disk is stored in a per-buffer
property, and all line-endings are converted to newline characters for
the in-memory representation. When the buffer is consequently saved, the
value of the property replaces newline characters when the buffer is
saved to disk.</para>
<para>There are several ways to change a buffer's line separator:
<itemizedlist>
<listitem>
<para>In the <guimenu>Utilities</guimenu>><guimenuitem>Buffer
Options</guimenuitem> dialog box. See <xref
linkend="buffer-opts" />.</para>
</listitem>
<listitem>
<para>By clicking the line separator indicator in the status
bar. See <xref linkend="status-bar" />.</para>
</listitem>
<listitem>
<para>From the keyboard, if a keyboard shortcut has been
assigned to the <guimenuitem>Toggle Line Separator</guimenuitem>
command in the <guibutton>Shortcuts</guibutton> pane of the
<guimenu>Utilities</guimenu>>
<guimenuitem>Options</guimenuitem>
dialog box. By default, this command does
not have a keyboard shortcut.</para>
</listitem>
</itemizedlist>
<para>By default, new files are saved with your operating system's
native line separator. This can be changed in the
<guibutton>Encodings</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box; see <xref linkend="encodings-pane" />.
Note that changing this setting has no effect on existing files.</para>
</section>
<section id="encodings">
<title>Character Encodings</title>
<para>A character encoding is a mapping from a set of characters to
their on-disk representation. jEdit can use any encoding supported by
the Java platform.</para>
<para>Buffers in memory are always stored in <literal>UTF-16</literal>
encoding, which means each character is mapped to an integer between 0
and 65535. <literal>UTF-16</literal> is the native encoding supported by
Java, and has a large enough range of characters to support most modern
languages.</para>
<para>When a buffer is loaded, it is converted from its on-disk
representation to <literal>UTF-16</literal> using a specified
encoding.</para>
<para>The default encoding, used to load files for which no other
encoding is specified, can be set in the
<guibutton>Encodings</guibutton> pane of the
<guimenu>Utilities</guimenu>>
<guimenuitem>Options</guimenuitem>
dialog box; see <xref linkend="encodings-pane" />.
Unless you change this setting, it will be your operating system's
native encoding, for example <literal>MacRoman</literal> on the MacOS,
<literal>windows-1252</literal> on Windows, and
<literal>ISO-8859-1</literal> on Unix.</para>
<para>An encoding can be explicitly set when opening a file in the file
system browser's
<guimenu>Commands</guimenu>><guisubmenu>Encoding</guisubmenu>
menu.</para>
<para>Note that there is no general way to auto-detect the encoding used
by a file, however jEdit supports "encoding detectors", of which there
are some provided in the core, and others may be provided by plugins
through the services api. From the encodings option pane
<xref linkend="encodings-pane"/>, you can customize which
ones are used, and the order they are tried. Here are some of the
encoding detectors recognized by jEdit: </para>
<itemizedlist>
<listitem>
<para> <emphasis role="bold">BOM</emphasis>: <literal>UTF-16</literal> and <literal>UTF-8Y</literal>
files are auto-detected, because they begin with a certain fixed
character sequence. Note that plain UTF-8 does not mandate a
specific header, and thus cannot be auto-detected, unless the
file in question is an XML file.</para>
</listitem>
<listitem>
<para> <emphasis role="bold">XML-PI</emphasis>:
Encodings used in XML files with an XML PI like the
following are auto-detected:</para>
<programlisting><?xml version="1.0" encoding="UTF-8"></programlisting>
</listitem>
<listitem>
<para> <emphasis role="bold">html</emphasis>:
Encodings specified in HTML files with a <literal>content=</literal> attribute in a <literal>meta</literal> element may be auto-detected:</para>
<programlisting><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"> </programlisting>
</listitem>
<listitem> <para> <emphasis role="bold">python</emphasis>:
Python has its own way of specifying encoding at the top of
a file.</para>
<programlisting># -*- coding: utf-8 -*- </programlisting>
</listitem>
<listitem> <para> <emphasis role="bold">buffer-local-property</emphasis>:
Enable buffer-local properties' syntax
(see <xref linkend="buffer-local" />)
at the top of the file to specify encoding. </para>
<programlisting># :encoding=ISO-8859-1:
</programlisting>
</listitem>
</itemizedlist>
<para>The encoding that will be used to save the current buffer is shown
in the status bar, and can be changed in the
<guimenu>Utilities</guimenu>><guimenuitem>Buffer
Options</guimenuitem> dialog box. Note that changing this setting has no
effect on the buffer's contents; if you opened a file with the wrong
encoding and got garbage, you will need to reload it.
<guimenu>File</guimenu>><guimenuitem>Reload with
Encoding</guimenuitem> is an easy way.</para>
<para>If a file is opened without an explicit encoding specified and it
appears in the recent file list, jEdit will use the encoding last used
when working with that file; otherwise the default encoding will be
used.</para>
<section>
<title>Commonly Used Encodings</title>
<para>While the world is slowly converging on UTF-8 and UTF-16
encodings for storing text, a wide range of older encodings are
still in widespread use and Java supports most of them.</para>
<para>The simplest character encoding still in use is ASCII, or
<quote>American Standard Code for Information Interchange</quote>.
ASCII encodes Latin letters used in English, in addition to numbers
and a range of punctuation characters. Each ASCII character consists
of 7 bits, there is a limit of 128 distinct characters, which makes
it unsuitable for anything other than English text. jEdit will load
and save files as ASCII if the <literal>US-ASCII</literal> encoding
is used.</para>
<para>Because ASCII is unsuitable for international use, most
operating systems use an 8-bit extension of ASCII, with the first
128 values mapped to the ASCII characters, and the rest used to
encode accents, umlauts, and various more esoteric used
typographical marks. The three major operating systems all extend
ASCII in a different way. Files written by Macintosh programs can be
read using the <literal>MacRoman</literal> encoding; Windows text
files are usually stored as <literal>windows-1252</literal>. In the
Unix world, the <literal>8859_1</literal> character encoding has
found widespread usage.</para>
<para>On Windows, various other encodings, referred to as
<firstterm>code pages</firstterm> and identified by number, are used
to store non-English text. The corresponding Java encoding name is
<literal>windows-</literal> followed by the code page number, for
example <literal>windows-850</literal>.</para>
<para>Many common cross-platform international character sets are
also supported; <literal>KOI8_R</literal> for Russian text,
<literal>Big5</literal> and <literal>GBK</literal> for Chinese, and
<literal>SJIS</literal> for Japanese.</para>

<title>The File System Browser (FSB)</title>
<para><guimenu>Utilities</guimenu>><guimenuitem>File System

<section>
<title>Navigating the File System</title>
<para>The directory to browse is specified in the
<guibutton>Path</guibutton> text field. Clicking the mouse in the
text field automatically selects its contents allowing a new path to
be quickly typed in. If a relative path is entered, it will be
resolved relative to the current path. This text field remembers
previously entered strings; see <xref linkend="history" />. The same
list of previously browsed directories is also listed in the
<guimenu>Utilities</guimenu>><guisubmenu>Recent
Directories</guisubmenu> menu; selecting one opens it in the file
system browser.</para>
<para>To browse a listed directory, double-click it (or if you have
a three-button mouse, you can click the middle mouse button as
well). Alternatively, click the disclosure widget next to a
directory to list its contents in place. To browse higher up in the
directory hierarchy, double-click one of the parent directories in
the parent directory list.</para>
<para>Files and directories in the file list are shown in different
colors depending on what glob patterns their names match. The
patterns and colors can be customized in the <guibutton>File System
Browser</guibutton>><guibutton>Colors</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box.</para>
<para>The <guibutton>Path:</guibutton> Text Box can be used to
navigate to a specific directory. Environment variables are expanded
here, allowing for both <literal>$VARNAME</literal> or
<literal>%VARNAME%</literal> syntax. </para>
<para> <literal>A+Up</literal> is a keyboard shortcut that brings
you to the parent directory. </para>
<para> <literal>A+Left</literal> and <literal>A+Right</literal> navigate back and forward through the visited directory stacks, in a
Netscape/Konqueror/IE like fashion. </para>
<para>To see a specific set of files only (for example, those whose
names end with <filename>.java</filename>), enter a glob pattern in
the <guibutton>Filter</guibutton> text field. This text fields
remembers previously entered strings. See <xref linkend="globs" />
for information about glob patterns.</para>
<para>Unopened files can be opened by double-clicking (or by
clicking the middle mouse button). Open files have their names
underlined, and can be selected by single-clicking. Holding down
<keycap>Shift</keycap> while opening a file will open it in a new
view.</para>
<para>Clicking a file or directory with the right mouse button
displays a popup menu containing various commands.
<!-- Note that attempting to delete a directory containing files will give an error; only empty directories can be deleted. -->
</para>
<tip>
<para>The file list sorting algorithm used in jEdit handles
numbers in file names in an intelligent manner. For example, a
file named <filename>section10.xml</filename> will be placed
after a file named <filename>section5.xml</filename>. A
conventional letter-by-letter sort would have placed these two
files in the wrong order.</para>

the file list from disk. F5 does this also. </para>
</listitem>
<listitem>
<para><guimenuitem>Root Directory</guimenuitem> - on Unix,
goes to the root directory (<filename>/</filename>). On
Windows and MacOS X, lists all mounted drives and network
shares. The forward slash (/) achieves this too. </para>
</listitem>
<listitem>
<para><guimenuitem>Home Directory</guimenuitem> - displays
your home directory. Keyboard shortcut: ~ </para>
</listitem>
<listitem>

<title>The Favorites Menu</title>
<para>Clicking the <guibutton>Favorites</guibutton> button displays
a menu showing all files and directories in the favorites list. The
<guimenuitem>Add to Favorites</guimenuitem> item adds the currently
selected file to the favorites list. If nothing is selected, the
current directory is added. To remove a file from the favorites,
invoke <guimenuitem>Edit Favorites</guimenuitem>, which will show

<guimenuitem>Delete</guimenuitem> from the right-click menu of the
entry you want to remove.</para>
</section>
<section>
<title>Keyboard Shortcuts</title>
<para>Completion behaves differently in file dialogs than in the
stand-alone file system browser window.</para>
<para>In the file dialog, keyboard input goes in the file name field
by default. Pressing <keycap>Enter</keycap> opens the file or
directory path that is either fully or partially entered in the file
name field. Typing the first few characters of a file's name selects
that file. If the file name field is empty and nothing is selected,
<keycap>/</keycap> lists the root directory on Unix and the list of
drives on Windows. There are two handy abbreviations that may be
used in file paths: <keycap>~</keycap> expands to the home
directory, and <keycap>-</keycap> expands to the current buffer's
directory.</para>
<para>For example, to open a file
<filename>/home/slava/jEdit/doc/TODO.txt</filename>, you might enter
<filename>~/j/d/to</filename>.</para>
<para>In the stand-alone file system browser, keyboard input is
handled slightly differently. There is no file name field, instead
shortcuts are active when the file tree has keyboard focus.
Additionally, pressing <keycap>/</keycap>, <keycap>~</keycap> or
<keycap>-</keycap> always immediately goes to the root, home and
current buffer's directory, respectively.

<section id="reloading">
<title>Reloading From Disk</title>
<para>When a view is brought to the foreground, jEdit checks if any open
buffers were modified on disk by another application. All affected
buffers are listed in a dialog box. By default, buffers without unsaved
changes are automatically reloaded. This feature can be disabled, or
changed to prompt if files should be reloaded first, in the
<guibutton>General</guibutton> pane of the
<guimenu>Utilities</guimenu>><guimenuitem>Options</guimenuitem>
dialog box; see <xref
linkend="global-opts" />.</para>
<para><guimenu>File</guimenu>><guimenuitem>Reload</guimenuitem> can
be used to reload the current buffer from disk at any other time; a
confirmation dialog box will be displayed first if the buffer has
unsaved changes.</para>
<para><guimenu>File</guimenu>><guimenuitem>Reload All</guimenuitem>
discards unsaved changes in all open buffers and reload them from disk,
asking for confirmation first.</para>
</section>
<section id="task-monitor">
<title>Task Monitor, and background I/O tasks</title>
<para>To improve responsiveness and perceived performance, jEdit
executes all buffer input/output tasks asynchronously. Plugins should
do the same.
When a task such as this is in progress, the status bar should display the number of running tasks and an icon that spins. If you do not see this, you can add the widget from the <xref linkend="status-bar-pane"/>. </para>
<para>The
<guimenu>Utilities</guimenu>><guisubmenu>Troubleshooting</guisubmenu>>
<guimenuitem>Task Monitor</guimenuitem> command displays a window with more
detailed status information and progress meters for each task. By default, the
<guimenuitem>Task Monitor</guimenuitem> is shown in a floating
window. This window can be docked using the commands in its top-left
corner popup menu; see <xref linkend="docking" />. Tasks can be aborted in this window, however note that aborting a buffer save can result in data loss.</para>

<section id="printing">
<title>Printing</title>
<para>jEdit printing is much like you'd expect from any text editor application, you can select the printer, specify specific pages to print, the number of copies, and a number of printer and page options that are supported by the printer such as color printing, duplex printing, and so on. The specific options available are determined by the chosen printer. Print preview is also available, as are several jEdit specific settings such as printing a header and/or footer, line numbers, etc.
</para>
<para>The printer dialog is accessed by <guimenu>File</guimenu>><guimenuitem>Print</guimenuitem>

In the Utilities - Global Options - Text Area settings, there is an option to show page break markers. If selected, horizontal lines will be displayed in the text area to indicate where page breaks will be when printing.</para>
<para>
There is also an action available in the View menu, to toggle the the page break markers on and off. Page break markers are just what they sound like, they show where page breaks would be for printing. Note that jEdit is not a word processor, so the page breaks are calculated based on printer settings and print font size. It is not possible to set a page break at a specific point in a file.
