libs=new("libraries")
The libraries object provides access to the list of libraries that are known on a system. Lists are returned in linefeed-delimited ($0A$) format, and each list row can be in one of two formats: just library path names, or all library details. A template can be obtained that describes the library information that is returned, so it is possible to develop routines that parse a list and obtain specific library information. A name-only template contains one field: pathname$. A detail template contains the following fields, delimited by a tab ($09$) or other character, if specified:
| • | basename$ - the base filename of the library path. |
| • | dirname$ - the directory portion of the library path. |
| • | path$ - the full library path. |
| • | category$ - the category, if any, of the library. |
| • | description$ - the library description |
| • | created$ - the library creation date, in yyyymmdd format |
| • | defperms$ - default permissions (r, w, and/or d) in semicolon-delimited format |
| • | forceseq - true (1) to force sequencers on sub IDs |
| • | inactive - true (1) if the library is inactive an no longer can be updated |
| • | count - the number of document records in the library |
Methods
createlib(library$[,errmsg$]) - creates a new library, fills errmsg$ if an error occurs.
|
dellib(library$) - remove library from library list (not from disk). Admin permissions required.
|
doccount(library$) returns the number of documents in a library.
|
exists(library$) returns true (1) if the library exists, false (0) otherwise.
|
getall$([detail[,delim$]) returns the names of all libraries, including inactive ones. If detail is true (1), then lines of detail are returned; if not, only path names are returned. If delim$ is not null, that is used as a template delimiter character; if it is null, a tab ($09$) delimiter is used.
|
getdelete$(userid$,[detail[,delim$]) returns the names of all libraries the specified user can delete from. If detail is true (1), then lines of detail are returned; if not, only path names are returned. If delim$ is not null, that is used as a template delimiter character; if it is null, a tab ($09$) delimiter is used.
|
getlib(library$,prop$) fills the template prop$ with library properties. The properties are as follows:
| • | prop.basename$ - the base name (no path information) |
| • | prop.dirname$ - the path information to the library |
| • | prop.path$ - the full path, including dirname and basename |
| • | prop.category$ - a category of the library, used to organize libraries in the browser interface |
| • | prop.created$ - yyyymmdd creation date |
| • | prop.defperms$ combination of r, w, and d, semicolon delimited |
| • | prop.forceseq - true (1) to force all sub ID's to have sequencing |
| • | prop.inactive - true (1) to make the library inactive, so no updates are allowed to the library |
| • | prop.count - the number of documents in the library |
| • | prop.aliases$ - semicolon delimited list of library alias names |
|
getnames$([detail[,delim$]) returns the names of all active libraries. If detail is true (1), then lines of detail are returned; if not, only path names are returned. If delim$ is not null, that is used as a template delimiter character; if it is null, a tab ($09$) delimeter is used.
|
getread$(userid$,[detail[,delim$]) returns the names of all libraries the specified user can read from. If detail is true (1), then lines of detail are returned; if not, only path names are returned. If delim$ is not null, that is used as a template delimiter character; if it is null, a tab ($09$) delimeter is used.
|
gettemplate$(detail[,delim$]) returns a string template definition for detail or non-detail return lines, optionally with the specified delimiter. If no delimiter is specified, a tab delimiter ($09$) is assumed.
|
getwrite$(userid$,[detail[,delim$]) returns the names of all libraries the specified user can write to. If detail is true (1), then lines of detail are returned; if not, only path names are returned. If delim$ is not null, that is used as a template delimiter character; if it is null, a tab ($09$) delimeter is used.
|
putlib(library$,prop$) update library with template prop$ (see getlib() for format). Admin permissions required. Note a library can't be renamed this way, only information properties such as category and description are updated.

The following code fragment illustrates how one could parse a library list.
o=new("libraries")
dim row$:o'gettemplate$(1)
rows$=o'getnames$(1)
x=pos($0a$=rows$)
while x>0
row$=rows$(1,x-1)
rows$=rows$(x+1)
libname$=row.basename$
libpath$=row.dirname$
libcount=row.count
x=pos($0a$=rows$)
wend
drop object o
