Call for Participation

A first Call for Participation that was combined with a survey was sent to the following reflectors on January 18, 2010: VHDL-AMS, DASC, SAE.org, VDA/FAT-AK30, ASIM/GI-WG Simulation of Technical Systems (STS), ASIM/GI-WG Fundamentals of Modeling and Simulation (GMMS), GI/ITG/GMMM-WG Description Languages and Modeling of Circuits and Systems (Fachgrupppe 4).

A second Call for Participation was sent to the Power Electronics, Aerospace and Electronics Systems, and Vehicular Technology societies of the IEEE on March 21, 2013.

Authoring Site-independent Twiki Pages

The twiki markup language provides means to author pages that are independent of the site that hosts the page. While this is not usually a big issue, site-dependent coding is a major headache when the twiki pages have to be moved to a new URL. This section provides a few hints how site independency can be achieved with judicious use of twiki variables.

The WYSIWYG editor contains a button to insert a link. Unfortunately, when the corresponding form closes it seems to always enter the complete URL of the link rather than allowing the link to be parameterized with twiki variables. In particular, if a variable reference is entered in this form, the value of the variable is used instead of the variable name. Use of this button should therefore be avoided. Better results can be achieved by editing the page in raw mode, i.e. at the twiki markup level. At this level the link is entered using the following format: [‍[<link>][text to display for link]].

Task	Format of link	Expands to
Link to another page in the same web	<page name>, e.g. P‍rojectsArea	http://www.eda-twiki.org/twiki/pub/P10761/ProjectsArea
Link to a page in another web	<web_name>.<page_name>, e.g. P‍1076.CollectedRequirements	http://www.eda-twiki.org/twiki/pub/P1076/Vhdl2019CollectedRequirements
Link to an attachment of the current page	%‍ATTACHURL%/<document_name>, e.g. %‍ATTACHURL%/SurveyCFP.pdf	http://www.eda-twiki.org/twiki/pub/P10761/WorkingGroupDocuments/SurveyCFP.pdf
Link to an attachment of another page	%‍PUBURL%/<web_name>/<page_name>/<document_name>, e.g. %‍PUBURL%/P1076/Vhdl2019CollectedRequirements/Proposal.txt. Use %‍WEB% for the current web.	http://www.eda-twiki.org/twiki/pub/P1076/Vhdl2019CollectedRequirements/Proposal.txt
Link to an anchor in a page	<page_reference>#<anchor_name>, e.g. W‍gOrganization#MailingList	http://www.eda-twiki.org/twiki/pub/P10761/WgOrganization#MailingList

Twiki variables of interest are:

Variable name	Meaning	Expands to
HTTP_HOST	The main URL of the site	www.eda-twiki.org
PUBURLPATH	The local path to the public webs	/twiki/pub
PUBURL	%‍HTTP_HOST%%‍PUBURLPATH%	http://www.eda-twiki.org/twiki/pub
WEB	The current web	P10761
TOPIC	The current page	WorkingGroupDocuments
HOMETOPIC	The name of the home page of the web, typically WebHome	WebHome
PARENTTOPIC	The name of the parent topic	WebHome
ATTACHURL	The URL of the current page, to be used with attachments of the page	http://www.eda-twiki.org/twiki/pub/P10761/WorkingGroupDocuments
ATTACHURLPATH	%‍PUBURLPATH%/%‍Web%/%‍TOPIC%	/twiki/pub/P10761/WorkingGroupDocuments
TOC	Table of content of current page	see at top of page

To escape the meaning of twiki markup on a page, the Twiki User Guide suggests to prefix the markup with an exclamation mark. This seems to work well to prevent a link to be created from a camel-case name, e.g. SunOS. In other places the exclamation mark does not survive repeated editing cycles (e.g. a space may be inserted between the exclamation mark and the name), or it has no effect (e.g. when trying to escape a variable expansion). All such issues can be avoided by inserting into the markup text the HTML character &zw‍j; (Zero width joiner).
