Module vs. "Pro" version
--------------------------
The E language source code of the EPM TeX Front End is provided, so that
you can generate either
* a module texfe.ex (as shipped with the distribution), or
* a complete EPM with integrated TeX Front End, the "Pro" version".
Compiling the EPM TeX Front End module
--------------------------------------
Compiling the file texfe.e by
ETPM texfe
generates the module texfe.ex.
Compiling the TeX Front End "Pro"
---------------------------------
Creating an EPM with integrated TeX Front End requires the following
steps:
1) add the contents of MYSTUFF.ADD to your file MYSTUFF.E
2) add the contents of MYMNUINI.ADD to your file MYMNUINI.E
(In case one of the above .E files does not exist, you just have to
rename the .ADD file.)
3) provide a suitable configuration file MYCNF.E. (See the sample
MYCNF.SMP that comes with the distribution.)
4) Compile the EPM, including the settings defined in MYCNF.E:
ETPM epm
Caution: Do not link texfe.ex or tex.ex with the Pro version!
emTeX vs. VTeX version
----------------------
This is controlled by the compile-time variable vtex, which may or may
not be defined in the general EPM configuration file MYCNF.E.
The statement
define vtex = 1
causes the EPM TeX Front End for VTeX/2 to be generated. Without this
variable, the `classical' TeX Front End for use with emTeX or Web2c will
be compiled.
Configuration constants
-----------------------
The following const's are read from the file MYCNF.E:
NLS_LANGUAGE
Set this const to 'DEUTSCH' in order to generate a German version.
Languages other than English (default) and German are currently not
supported. Caution: In order to compile a German version of the
full EPM you need the file DEUTSCH.E which is NOT part of the free
EPM package!
WANT_TEX_MENU
Define const WANT_TEX_MENU = 0 in MYCNF.E to omit the TeX menu. Do
_not_ add the contents of MYMNUINI.ADD to MYMNUINI.E in case you
compile the Pro version without the menu! The default value is 1,
so that the menu is usually included.
LATEX_SYNTAX_INDENT
Indentation within LaTeX environments. The default value is 2 (not
depending on SYNTAX_INDENT).
WANT_STREAM_INDENTED
This const applies to the the basic EPM, not to the TeX Front End.
Setting it to 1 makes the <enter> key move the cursor always to the
starting column of the previous line. This is useful in conjunction
with EPM's syntax assist for LaTeX and other `languages'. Defining
WANT_STREAM_INDENTED requires, however, compilation of the full EPM,
either with or without built-in texfe.
WANT_CTRLA
const WANT_CTRLA = 1 will map the bracket matching facility of the
EPM, which is usually triggered by Ctrl-[, to the Ctrl-a key, too.
This is particularly useful with, e.g., the German keyboard, where
the original key assignment would require pressing Ctrl-AltGr-[.
The German versions were compiled with this feature turned on.
WANT_INCLUDEONLY_SUPPORT
const WANT_INCLUDEONLY_SUPPORT = 1 will enable a special facility
related with master file support: When master file support is ON
and TeXing is requested while an included file is being edited, then
the EPM will search the master file for an \includeonly command and
will replace its argument with the name of the file being edited.
If there is no \includeonly command found, or if it has been
commented out, all dependent files will be included, as usual. The
facility is also disabled when a marked region is to be typeset.
There are, however, some important restrictions:
* Only the stem of the filename (neither the path nor the extension)
is passed to the \includeonly command. As a result, the included
file must reside in the same directory as the master file, it must
be of type '.tex', and the path must not be specified.
* The filename is passed in lowercase to the \includeonly command,
so you have to use lowercase in the corresponding \include command,
too.
* The \includeonly command must not be split into two or more lines.
* The \includeonly command must be the only one on its line.
EXTENDED_LATEX_ASSIST
const EXTENDED_LATEX_ASSIST = 1 forces Juan J. G. Ripoll's
experimental auto-indentation and reflowing package for LaTeX to be
included. LATEX_SYNTAX_INDENT is ignored then, and the settings
menu will provide an item for specifying the right margin. The
syntax assist facility will slightly differ from the one of the
original TFE. See <http://www.arrakis.es/~worm> or
<mailto:worm@arrakis.es> for the source code of this package.
This package cannot be added to the EPM TeX Front End for VTeX.
Sample EPM configuration file
-----------------------------
The free EPM differs very much from the version shipped with Warp 4,
most noticeably as far as the menu structure is concerned.
Unfortunately the help texts and the User's Guide reflect the Warp
version, and there is no configuration file included with the "BBS"
package to create the latter. Besides, there are some features missing
in the BBS version.
I have provided a configuration file MYCNF.SMP, which includes all the
information required to create the "Warp 4 EPM". Rename it to MYCNF.E
to make the compiler include it. The file contains information how and
where personal settings and useful extras like syntax assist can be
added. I recommend including this file for compiling the "Pro" version.
Re-compile the spell-checking module EPMLEX, too, using this MYCNF.E!
Please, note the changes to MYCNF.SMP introduced with v2.2: Syntax
assist for C and Java is now enabled, and a bug with the TAGS facility
has been fixed. As with v2.4, the EPM will be configured so as to
auto-convert Unix-style line endings to DOS style.
*** Use of this file does not depend on the texfe being linked! ***
*** Notice that the file MYKEYS.SMP is no longer provided! ***
Special features of the "Pro" version
-------------------------------------
* The menu items "Folder" and "Shell" are put into the existent "File"
and "Command" submenus (in German: "Datei" and "Befehl") if the
standard menu layout STDMENU.E is included upon compilation; otherwise
an additional "OS/2" submenu is provided for them.
* Master file support can be toggled either in the settings window or
via a separate item in the TeX submenu.
* The actions of the TeX menu are disabled, when the related files are
missing.
Debugging
---------
The TeX Front End provides the EPM command
tex_debuglevel
Enter this command to see the current debug level, initially 0. Enter
tex_debuglevel 1|2|3
to get debugging information in the EPM message line:
Debug level | Action
--------------------------------------------------------------
|
> 0 | trace all 'cd' commands
|
= 1 | display the external commands to be launched
|
> 1 | trace parsing of the TeX transcript file
|
> 2 | ditto, but lots of information (don't use it!)
The debug level is set to 0, when the EPM starts up.
