Ndihmë:Gabimet CS1

Kjo faqe pë të raportuara nga moduli CS1 (moduli përgjegjës për procesin e referimit), kuptimin e tyre dhe si këto gabime mund të rregullohen nga redaktuesit.

|access-date= requires |url=

Data e aksesimit është data në të cilën është shtuar një adresë interneti te burimi. Data e aksesimit duhet për të verifikuar deri në çfarë date adresa ka qenë funksionale, në rast se në të ardhmen adresa ndalon së funksionuari. Nëse një burim ka një datë aksesimi pa një adresë interneti shfaqet mesazhi në fjalë. Burimet pa adresë interneti nuk kanë nevojë për datë aksesimi.

Për ta rregulluar këtë gabim mjafton të shtoni adresën e munguar të internetit ose të hiqni parametrin e datës së aksesimit, sipas nevojës së rastit.

Faqet me këtë gabim renditen automatikisht nën kategorinë Faqe që përdorin datë aksesimi pa parametër adrese.

|archive-url= is malformed

Faqja Archive.org funksionon si një arkivë për faqet e internetit. Ka dy forma si mund të jetë një adresë nga kjo faqe:

https://web.archive.org/<timestamp>/... – forma e vjetër

https://web.archive.org/web/<timestamp><flags>/... – forma e re

Shpeshherë mund të ketë gabime në mënyrën si shkruhet adresa e faqeve të arkivuara. Kur një gabim i tillë ndodh, mesazhi i gabimit indentifikon arsyen konkrete të gabimit dhe e nxjerr atë anash. Arsyet e mundshme janë:

– komanda save është the archive.org url

– pritej pjesa web/ por diçka tjetër u zbulua në vend të saj

– pjesa timestamp e adresës nuk përmban 14 shifra

– pjesa flag e adresës nuk përbëhet nga dy shkronja të vogla të ndjekura nga një nënshkrim: 'id_'

– liveweb.archive.org është një formë e vjetër e emrit të domenit

Kur adresa për archive.org ka ndonjë nga këto gabime moduli nuk arrin të bëjë lidhjen dhe nxjerr mesazhin përkatës. Gabimi rregullohet duke rregulluar adresën në pjesën e saj problematike.

{{cite web | http://www.foobar.com | The Foobar Bar}}

The citation is "empty" because it does not contain the necessary parameter identifiers (in this case |url= and |title=) that tell {{cite web}} how to use the information that the citation does contain.

A citation is also marked as "empty" when it contains only parameters that it doesn't recognize:

{{cite book |titolo=The Foobar Bar |anno=2015}}

This citation is empty because the Italian-language parameters |titolo= and |anno= are not recognized as valid parameter names on the English Wikipedia.

"Empty citation" may also mean that an editor meant to use another template entirely. Perhaps the editor used {{citation}} when the intent was to use {{citation needed}} or {{quote}}.

Citation Style 1 and Stampa:Cs2 templates requires a |lastn= parameter for each |firstn= parameter in a citation. Author and editor lists are checked for proper last/first pairing. CS1|2 will emit this error message for the first mismatch it detects. If there are more last/first mismatches in a citation, subsequent mismatches are not detected.

There is no requirement that each |lastn= have a matching |firstn=.

The error message uses a sort of shorthand: |lastn= can refer to any of the legitimate |author= aliases in the authors list. Similarly, |lastn= refers to any of the |editor-last= aliases in the editors list.

To resolve this error, ensure th These err templates us without also providing a corresponding URL for |url= or |...-url=, respectively, etc.). In some cases an editor may have intended to use |type= to specify a kind of document (e.g. hard cover, paperback, pamphlet, etc.) The |format= and |...-format= value is always displayed.

The list of |...-format= parameters is:

|archive-format=, |chapter-format=, |conference-format=, |contribution-format=, |event-format=, |lay-format=, |section-format=, |transcript-format=

As of 29 November 2014, |chapter-format= is a new parameter. Citations that relied on the old, somewhat odd use of |url= and |format= may need adjustment.

To resolve this error, remove |format= or |chapter-format=; define |url= or |chapter-url=; or change |format= to |type= (or to |chapter-format= if |chapter-url= is used without |url=.

So that all authors and editors are listed in a rendered citation, Citation Style 1 and Stampa:Cs2 templates requires n in |lastn= (and its aliases) to increment by 1 for each author or editor. This error message is emitted when there is a 'hole' in the numbering (an author list made up of |author1= and |author3= but without |author2= for example).

The test will not detect a 'hoat is larger than 1. It is presumed that when |authorn= and |authorn+1= are both not present, then the test has reached the end of the list.

Missing or empty |title=

There are two slightly different error conditions that can arisens lack appropriate titles. In each case, CS1 reports this error message. The necessary resolution may vary depending on the cause of the error. The error message links to the appropriate description below.

Bare URL without a title

Stampa:Help deskhis error when one of the URL-containing parameters cannot be paired with an associated title. This error may also occur when |title= cannot be linked with |url= because the citation also contains a conflicting |title-link= parameter.

A unique case exists: if |pmc= has a value and |url= is omitted or empty, then |title= is linked with the same URL as the PMC.

Because URLs are ugly and generally uninformative, it is expected that editors should provide a meaningful title for each URL. In most cases this can be accomplished by using the |title= parameter.

To resolve this error, provide an appropriate title for the URL-containing parameter. In the case where |url= and |title-link= are contending for |title= you must choose which one to keep. Consider moving |url= or |title-link= to a more suitable parameter.

Pages with this error are automatically placed in Category:Pages with citations having bare URLs.

Citation without a title of any form

This error occurs for Citation Style 1 and Stampa:Cs2 templates when all of |title=, |trans-title=, and |script-title= are omitted or left blank. At least one of these title parameters must be provided for each citation.

{{cite episode}} will show this error if |series= is omitted or left blank (even if a |title= is provided).

Sometimes this error occurs because an editor has used a CS1|2 citation as a shortened footnote when {{sfn}} or one of the {{harv}} family of templates would have been more appropriate. This error also occurs when an editor used {{citation}} but intended to use {{citation needed}}.

To resolve this error, provide a value for |title=, |trans-title=, and/or |script-title= or replace the CS1|2 template with a more appropriate template. If you are listing a periodical or an issue of a periodical in a bibliography rather than within <ref>...</ref> tags, {{List journal}} may be more appropriate.

Pages with this error are automatically placed in Category:Pages with citations lacking titles.

Missing or empty |url=

This error message is reported by {{cite web}}, {{cite podcast}}, and {{cite mailing list}} when the template parameters |url= and |archive-url= are both missing, blank or not properly entered. Note that |website= or |work= is the name of the site, not the URL.

To resolve this error, provide a value for |url= or use a more appropriate template such as {{cite book}}, {{cite journal}} or other Citation Style 1 or Stampa:Cs2 template.

Pages with this error are automatically placed in Category:Pages using web citations with no URL.

More than one of |<param1>=, |<param2>=, and |<param3>= specified

This error occurs when a Citation Style 1 or Stampa:Cs2 template includes more than one parameter that maps to the same meaning. For example, |author=, |last=, and |last1= are all synonyms of each other, so no more than one of these parameters should ever be used in a single template.

To resolve this error, remove or modify the redundant parameter(s).

This error occurs when a CS1 or CS2 template uses more than one type of author or editor name-list style. There are three kinds of incompatible author-name-list styles:

|authorn= and |lastn= / |firstn= (and their various aliases), |vauthors=, and |authors=

and similarly, three editor-name-list styles:

|editorn= and |editor-lastn= / |editor-firstn= (and their various aliases), |veditors=, and |editors=

To resolve this error, choose one name-list-style. Use the chosen style for both of the author and editor name-lists.

Pages with these errors are automatically placed in Category:Pages with citations having redundant parameters.<

Text "????" ignored

Unlike many Wikipedia templates, the Citation Style 1 and Stampa:Cs2 templates do not use unnamed or positional parameters. When a citation contains text between vertical bars and that text does not contain an equal sign (=), CS1|2 ignores the text and reports the error. This is true even when the text is the name of a valid parameter.

This error can also be caused by vertical bars that are part of URLs or titles. When vertical bars occur in URLs, replace each vertical bar with %7c. When vertical bars occur in parameter values that are not URLs, replace each vertical bar with | or {{!}}.

To resolve this error, remove the extraneous text, add '=', add an appropriate parameter name from the template you're using to complete the parameter, or properly encode vertical bars in URLs and titles.

Citation Style 1 and Stampa:Cs2 templates report this error when the citation has an English translation of the title in |trans-title= or chapter title in |trans-chapter= but does not have the original-language title in |title= or original-language chapter title in |chapter=.

To resolve this error, provide the original language title for |title= or chapter title for |title=. Consider adding |language= if not already part of the citation.

Citation Style 1 and Stampa:Cs2 templates report this error when the name portion of a parameter's |name=value pair is not recognized as a valid name. Typically, this is caused by spelling or capitalization errors.

With the old-style citation templates, it was possible to include information within the template that was simply ignored as unrecognized parameters. The Lua-based CS1|2 engine does not ignore unrecognized parameters. The purpose of the citation is to properly identify the source; not act as a repository of notes and ancillary information.

CS1|2 template parameters are lower case. CS1|2 will report this error when the parameter's name contains uppercase letters (Stampa:!xt) but the parameter's name is defined as lowercase (xxxx). The identifier parameters, like |isbn=, |pmc=, |doi=, etc., can be either lower case or upper case, but not of mixed case (|isbn= or |ISBN= but not Stampa:!xt). For common parameter misspellings, like |pubisher= instead of |publisher=, CS1|2 will suggest a valid parameter name.

To resolve this error, replace the erroneous parameter name with a correct one, possibly using the suggested name. Ensure that the parameter's name is correctly spelled and that there are no characters except spaces between the parameter's name and the leading vertical bar (|) or trailing equals sign (=). A list of valid parameters can be found by consulting Help:Citation Style 1 or visiting the description page of the specific template being used, such as {{cite web}}, {{cite book}}, {{cite journal}}, etc. er ing information associated with the unknown parameter into an appropriate parameter or to a section of the article's talk page for preservation.

Unsupported parameter(s)

{{cite arXiv}} uses a limited subset of the common Citation Style 1 parameters. This error message is emitted when parameters not in the {{cite arXiv}} subset occur in a {{cite arXiv}} template.

To resolve this error, remove the unsupported parameters. See Template:Cite arXiv for the complete list of supported parameters.

Pages with this error are automatically placed in Category:CS1 errors: arXiv.

URL–wikilink conflict

External links in a rendered citation are a combination of url-holding parameters, |url=, |chapter-url=, etc., with title-holding parameters, |title=, |chapter=, etc. Title-holding parameters may be wikilinked to another Wikipedia article but not when there is a matching url-holding parameter in the citation. When this condition occurs, the wikilink is suppressed, the wiki markup ignored, and the rendered citation links to the external site.

Some templates will also cause this error if they are part of a title-holding parameter. The error occurs when the template produces wikilinked content. For example, {{lang}} templates output a wikilinked category. Templates in url-holding parameters may also corrupt the citation's COinS metadata. As a general rule, avoid using templates in title-holding parameters unless you know that the template's effects are entirely visual ({{!}} and the like).

This type of error may also occur in identifier-based templates ({{cite doi}}, etc.). When this happens, the error message is shown in the article but the error is actually located in the identifier-based citation template.

To resolve this error, remove wikilinks from title-holding parameters that are intended to be externally linked or remove the external URL, which will allow the internal wikilinks to work as expected. If wikilink-producing

Vancouver style error

This error is reported for citations that use |name-list-format=vanc. Vancouver style restricts author or editor names to the Latin alphabet. For the purposes of this test, Module:Citation/CS1 defines the Latin alphabet as the letters defined in the Unicode Latin character sets:

C0 Controls and Basic Latin (0041–005A, 0061–007A)

C1 Controls and Latin-1 Supplement (00C0–00D6, 00D8–00F6, 00F8–00FF)

Latin Extended-A (0100–017F)

Latin Extended-B (0180–01BF, 01C4–024F)

This error is also reported when a corporate or institutional author is listed in |vauthors= without proper delimiters. Corporate authors should be listed this way:

|vauthors=First Surname FM, Surname AB, Stampa:GreenCorporate or institutional AuthorStampa:Green, Lastsurname XY

This error is also reported when more than two initials are used: in case of more than two initials, list only the first two.

While normally correct, sometimes the names listed on a PMID page contain errors when the author surname has a lowercase nobiliary particle. For example, Stampa:PMID lists Magnus von Knebel Doeberitz as Doeberitz Mv which is not correct. This author's name should be listed as |vauthors=von Knebel Doeberitz M.

Certain punctuation will be flagged as an error. For example, Unicode U+2019, right single quotation mark, causes an error because it is not a member of the Latin character sets identified above: |vauthors=VanStampa:Redt Veer M. Replace this character with the straight (or typewriter) apostrophe: |vauthors=VanStampa:Greent Veer M.

To resolve this error, Romanize author and editor names. Romanizing can result in two-letter initials, for example, the Greek letter 'Θ' Romanizes to 'Th'. When author names have this kind of initial, Module:Citation/CS1 can't know if this kind of initial is a typo or a legitimate Romanized character so it will emit the Vancouver error. To suppress the error after determining that the two-character initial is correct and not a typo, treat the name as if it were a corporate name by wrapping it in doubled parentheses: |vauthors=..., Tatarinov IuS, ... → |vauthors=..., ((Tatarinov IuS)), ...

Similarly, Chinese hyphenated given names may appear in PubMed listings. For example: 'Wang Hsien-yu' may be listed on PubMed as 'Wang Hy' which will result in a Vancouver error. When this occurs, and upon verification that such names are correct, wrap them in doubled parentheses.

C0 control, U+

C1 control, U+0080–U+009F (XXX–APC)

To resolve invisible-character errors, remove or replace the identified character. Because these characters are mostly invisible, the error message identifies the character's position in the parameter value counted from the left. Space characters between the assignment operator (the '=' sign) and the parameter value are not counted.

Stripmarkers are special sequences of characters that MediaWiki inserts as a place-holder for certain xml-like tags. These tags include <gallery>...</gallery>, <math>...</math>, <nowiki>...</nowiki>, <pre>...</pre>, and <ref>...</ref>. The stripmarkers are replaced with content before the final page rendering. The module ignores math and nowiki stripmarkers.

To resolve stripmarker errors, remove or replace the identified tag. The error message identifies the stripmarker's position in the parameter value counted from the left. Space characters between the assignment operator (the '=' sign) and the parameter value are not counted.

Stripmarker errors can also be caused by unsupported additional text or templates in parameter values. Resolve the problem by moving the extraneous text outside of the citation template or by removing the extraneous text, as appropriate.
