[Tex/LaTex] Is it possible to type LaTeX code and see its real time preview in LyX

lyxpreview

I'm new to LyX. I have just given it a try and written my first article.

I discovered a panel from Menu > View > View Source. It shows the source code of my article. But as far as I see, I am not able to edit this code preview panel. I want to edit both the panels. I want the other panel automatically update itself as I type one panel (like the split panels of code/design in Adobe Dreamweaver). If editing both the panels is not possible, at least I want to do it on the reverse; I only want to work on code and see its preview real time.

Is this possible in LyX?

Best Answer

There is the possibility in LyX to preview graphics and math formulas. The settings can be found under "Tools > Preferences..." then "Look & Feel > Display". (Internally, LyX uses the preview package of LaTeX, see http://wiki.lyx.org/LyX/InstantPreview.)

instant preview of math formula This is how your example looks with instant preview on.

Furthermore, LyX is a document processor that generates LaTeX code. As you have discovered you can preview the generated code but you cannot edit this. Nevertheless, you can

insert LaTeX code via "TeX code/ERT" (Ctrl+L), or
insert entire LaTeX files via "Insert > File > Child Document...".

$$-variables

The $$<letter> variables refer to the following (from the LyX Customization manual, found under Help --> Customization, section 3.3):

$$s The LyX system directory
$$i The input file
$$o The output file
$$b The base filename of the input file (i.e., without the extension)
$$p The path to the input file
$$r The path to the original input file (this is different from $$p when a chain of converters is called)
$$e The iconv name for the encoding of the document.

Extra flag

Quoting the manual mentioned above:

In the Extra Flag field you can enter the following flags, separated by commas:

latex This converter runs some form of LaTeX. This will make LyX's LaTeX error logs available.

needaux Needs the LaTeX .aux file for the conversion.

xml Output is XML.

The following three flags are not really flags at all because they take an argument in the key = value format:
parselog If set, the converter's standard error will be redirected to a file infile.out, and the script given as argument will be run as:
script < infile.out > infile.log.  The argument may contain `$$s`.
resultdir The name of the directory in which the converter will dump the generated files. LyX will not create this directory, and it does not copy anything into it, though it will copy this directory to the destination. The argument may contain $$b, which will be replaced by the base name of the input and output files, respectively, when the directory is copied. Note that resultdir and usetempdir make no sense together. The latter will be ignored if the former is given.

resultfile Determines the output file name and may, contain $$b. Sensible only with resultdir and optional even then; if not given, it defaults to index.
