What is the best way of inserting python/C++ code in a Lyx document? The code is small examples less than 20 lines.
My Lyx document is using the Book document class.
Orjanp
I prefer to insert the listings as a child document, so the code is grabbed directly from a file that you can further edit and keep updated (you avoid to duplicate an information and maintenance is a lot easier).
To do this in Lyx:
Insert->File->Child document
Then in the window that will appear change the type to program listing and configure it as you need, for example you could want to enter the parameter language=Python (you can type a ? to view all the parameters).
A set of parameters I usually use is:
breaklines=true //--> breaks lines to margin
captionpos=b //--> caption at the bottom of the listing (default is "t")
frame=tb //--> frame at the top and at the bottom of the listing
language=Python //--> syntax highlighting for python
There should be an Insert -> Program Listing option. That uses listings Latex package, so you should have that installed. The support seems to have been added in Lyx 1.5, and from their screenshot, it seems it gives you a lot of customization options.
The insert->Program Listing feature works great. I just want to add that if you are on Mac, and try to directly paste, using command+V or right-click+paste, a block of code into the program listing, the whitespace will not be preserved, and you have to manually insert the whitespace by typing tabs, returns, etc.
A very easy way to get around this is is to paste using shift+command+V. This preserves all the whitespace of your original source code.

TLDR - how do I use either a custom parser function or modify the loop module to it'll add a newline after each iteration?
Long story:
I'm using old templates that used to be rendered with some MS tools, now trying to render them with docxtemplater. Main requirement is to not modify the templates. Use them as they are, and be able to render documents as identical as possible to that MS tool.
Here's what a loop looks like in one of the templates:
«TableStart:MortgageInfo»« MortgageInfo_Name»
« MortgageInfo_MortgageStreet»
«CityStateZip»«TableEnd:MortgageInfo»
I used custom delimiters for « and » and created a custom loop module to handle the custom TableStart: and TableEnd: format.
There is no linebreak between «CityStateZip» and «TableEnd:MortgageInfo» so the 2nd item is rendered immediately after the 1st without a linebreak.
Anybody has any idea how I add this missing linebreak? Please bare in mind - no modification to the template is allowed...
I am using IBM DiffMerge to generate a Report that shows all differences between two .cls files or .sbs files. I was playing with it and I saw that there is a filed in option menu that allows you to change the format of the report, but it implies some keywords, like $elemname to print the element's name or $elemtype to print its type $leftonly or $rightonly which show how many differences are in the left diagram or in the right one.
Now, I was wondering if there are more variables like those above, especially one that can print a component's GUID (unique ID in Rhapsody).
Thanks,
Daniel
I would expect that $GUID will give you what you're looking for.
Under the ReporterPlus installation folder there is a folder named Templates. In it you'll find a file named DiffReport.dpl which you can load it into ReporterPlus for editing like any other template. You must run Rep+ with a command line option so that it loads with the Diffmerge specific schema:
Reporter.exe /mode=dfm
After that you can load the Diffmerge template, and edit it to customize the output of DiffMerge reports. When you do, try adding $GUID into the output.

I have two blue prints for the space content type in OA. On the toolbar dropdown i want to show only the spaces created using the default blue print. AO uses the oa_core_get_groups_by_user_access(found in OA core module in the oa_core.util.inc file) to pull all spaces a use subscribed to. I want to alter this function to show only spaces created using the default blue print by altering the query used in this function.
All my attempts to do so have failed probably because i don't understand the drupal database abstraction queries. Can someone help me with the piece of code i can add to this function to achieve this functionality.
Finally got it. To show only the default spaces in the dropdown, you have to make changes to the oa_core_get_titles function in the oa_core_util.inc file of oa_core.
Add the following line below line 641 of that particular file.
$query->leftJoin('field_data_field_oa_space_type','t','n.nid=t.entity_id');
$query->condition('t.field_oa_space_type_tid',1);
This filters out only spaces created using the default space.
I'm trying to modify my /portal_view_customizations/zope.interface.interface-plone.belowcontenttitle.documentbyline template with a tal expression, so that the document's author and the modification date do not show if the current portal type is a Document (Page). I don't mind if it shows for News Items, which are time sensitive, but not the Documents/Pages.
This is my failing Plone TAL expression:
<div class="documentByLine"
id="plone-document-byline"
i18n:domain="plone"
tal:condition="view/show and not:python:here.portal_type == 'Document'">
...
I've also tried:
<div class="documentByLine"
id="plone-document-byline"
i18n:domain="plone"
tal:condition="view/show and not:context/portal_type='Document'">
but still no luck. The tracebacks are pretty cryptic and don't relate to the TAL expression. However, if I get rid of my condition for portal_type, then it works again. Any thoughts are appreciated. A manual would be good, but I've looked at the official ones, and they don't mention this.
TAL's underlying TALES, the expression-engine of which TAL makes use of, doesn't support the mixing of expression-types in one expression. It's syntax allows only one expression-type to be specified (defaults to 'path', if omitted, btw), as no delimiter is provided (like a semicolon for chaining several TAL-statements in one element, e.g.).
But instead of mixing three expression-types you can use one python-expression, try:
python: view.show and context.portal_type()!='Document'
Update:
If you have customized a Plone's default-template via portal_view_customizations ('TTW'), now restricted python-methods cannot be accessed, that' why view/show throws an error.
It returns the allowAnonymousViewAbout-property of the site-properties, you can also check this condition yourself and your expression looks like:
tal:define="name user/getUserName"
tal:condition="python:test(name!='Anonymous User') and context.portal_type()!='Document';
Quick'n'dirty alternative:
Do it with CSS:
body.userrole-anonymous .documentByLine {display:none}
body:not(.template-document_view) .documentByLine {display:block}
This will render the hidden elements, but it's helpful for prototyping and such, or 'quickfixes' (no admin available, etc.).
I would like to restrict the fields while creating a new post in WordPress. For the title, it should not exceed 40 characters. For the content, it should not exceed 400 characters. If these maximum values are exceeded, I would like to show an error message and not let the user continue. How do I do that in WordPress?
You should be able to use wordpress filters to modify the code that gets outputted when the editor is called. Essentially you would want to use it to insert some javascript and an extra div tag to display your error, then just read the contents of the "editorcontainer" id and show the error once it reaches a certain character limit.
I don't have the time at the moment to write a case example, but depending on your skill level, the functions you are looking for are:
apply_filters("the_editor", "customfunction_limitarea");
Where customfunction_limit area is your created function to insert the javascript. You can see how the_editor is currently called and how the default filters are applied in "wp-includes\general-template.php" on line 1822. The default looks like this:
$the_editor = apply_filters('the_editor', "<div id='editorcontainer'><textarea rows='$rows'$class cols='40' name='$id' tabindex='$tab_index' id='$id'>%s</textarea></div>\n");
I would try modifying that statement by placing a new filter in a functions.php file located in your themes directory, that way you don't have to worry about it getting over-written during an update. Otherwise, if you absolutely have to edit the wordpress core (generally a no-no), general_template.php would be the place to do it I think.
Essentially just read up on wordpress filters a little bit (be warned there's not a ton of documentation or examples available for it other than the basic stuff), and that should provide everything you need. The input verification end is easy enough to find scripts, just google jquery post limiting. Something like this might be exactly what your looking for:
