Spaces and comments inside commands and equations are OK now, but while testing with a large document I found some differences respect to version 1.0.2. I'm not sure if they are related or not with spaces or with the changes done to correct this bug.

• The contents of a child document that is inside a comment (menu: Insert->Note->Comment in LyX) are shown with last version, but with LaTeX or with eLyXer 1.0.2 they are not shown. This only occurs with the contents of the child document, but the text directly in a Note-Comment is not shown.

Although with version 1.0.2 the contents of the child document inside comment were erroneously included in the table of contents and the subsequent chapter, section, subsection, etc. numbers were affected.

• The chapters, sections, subsections, etc. numbering is shown twice for the sections inside all the child documents but shown normally for sections in the master document. Also in Table of Contents the title of the sections inside child document are shown with an extra space at the begining.

Attached 3 test documents (master.lyx, child1.lyx, child2.lyx) to show both problems and compare results of rendering.

(file #21649, file #21650, file #21651)

Empty equation and lone comment are OK.

Comment inside \mbox (and similar) almost correct, except when there is nothing after the comment. In this case there is a message error and the closing "}" is shown in conversion. The LyX file in the attach (eqmboxcom.lyx) have 3 test cases, first and second are OK, the third one gives the following messages:

---

Line 90: Unrecognized formula at }
Line 90: * Pending endings [Ending }] left open
Line 90: * No ending out of bounds
Line 90: * Expected ending }, got
Line 90: * Pending endings [Ending }] left open

Yes, this one works well with all the previous cases.
 
I was not able to imagine a new case to torture eLyXer, but by chance I got a message in a simple file without any apparent equation. It turned out to be just an empty equation left from other tries.
So, just create an equation (inline or displayed) in LyX, and move cursor out of it without typing anything inside. The edition box disapears, but equation remains hidden, and eLyXer convert it to a red '*' (unknown) and it shows the message:
Line 60: Unknown formula at:

Also the same message occurs if there is just only a comment inside an equation.

Another different case was found also by chance. When editing an equation and then pressing Ctrl-m inside it, LyX inserts an "\mbox". The problem is that comments inside that mbox are shown in conversion done by eLyXer (including the % symbol), but LaTeX correctly does not show them. The same occurs with comments inside other functions like "\textrm", etc.

Thanks,
Jose R.

With comments inside commands in the LaTeX preamble it works OK, even with more than a comment line and with a blank line.

I tried also to insert a comment inside an equation through LyX equation editor (monitoring at the same time with view source active) and, surprisingly, by typing "\%" inside an equation LyX automaticaly inserted the comment and a new line in the source (to insert spaces inside the comment you need to type "\ "). The file is correctly rendered with LaTeX.

If the comment in equation is inserted inside a function element, like "\frac" (see attached example "cmeq1.lyx"), then the conversion by eLyXer is done (incorrect in the equation) but there is a message:

---

Line 53: * Pending endings [Ending }] left open
Line 53: * No ending out of bounds
Line 53: * Expected ending }, got
Line 53: * Pending endings [Ending }] left open
Line 53: No parameter found at:
Line 53: * Pending endings [Ending }] left open
-----

If the comment in the equation is inserted outside function elements (see attach example "cmeq2.lyx") then the conversion fails and eLyXer crashes with error messages copied in the attach "cmeq2-error.txt".

Thanks,
Jose R.

Well, that way to insert comments inside commands is not very usual. Also, with your last version it was able to do the conversion without crash, it just give a message about the command being ignored, so this is only a minor problem.
Thanks a lot for your work.

Yes, the version attached in your comment #2 solves the initial problem with spaces after renewcommand in preamble in my system.

I just tested it with an example file that caused the error with elyxer 1.0.2, but with your patched copy of elyxer.py it work correctly. It even works inserting a new line after \renewcommand.

But also inserting a comment after \renewcommand like the following (in the preamble):
   \renewcommand % comment
   {\labelenumi} {\Alph{enumi}.}

does the conversion but also gives a message in stderr:
Line 46: Unknown formula bit in defining function at % comment
 {\labelenumi} {\Alp

The comment at the end of line is accepted viewing the DVI without any problem.

Thank you very much for your fast reply.

Hi José Ramón,

The problem was easy enough to reproduce with your detailed description. For starters I avoided the crash; now eLyXer just ignores the definition if it does not understand any piece of it.

I found after a quick search that spaces in math mode are supposed to be ignored, so I am going to implement just that. Are you interested in testing the solution? If so I can send you a test version (and add you to the acknowledgements as a tester!).
