log! clj/s

(log! entry-type & args)

Side-effect: adds an entry to log-graph for id minted per entry-type and args Returns: id or nil (if no entry was made) Where

• id is a KWI minted for entry-type and whatever arg-kwis are of :rdf/type :glog/InformsUri in @log-graph.
• entry-type is a KWI
• args := [arg-kwi value, ...] Note: Any issues relating to log levels should be handled before calling this function.

log-graph clj/s

log-reset! clj/s

(log-reset!)

(log-reset! initial-graph)

Side-effect: resets @log-graph to initial-graph Where

• <initial-graph> is an IGraph, informed by ont-app.graph-log.core/ontology
  • optional. Default is core/ontology.

log-value! clj/s

(log-value! entry-type value)

(log-value! entry-type other-args value)

Returns value Side effect: logs <id> :glog/value value, plus other-args into log-graph Where

• entry-type is a keyword naming the type of entry
• value is the value being logged before it's returned.
• other-args := [p o, ...]
• entry is an entry in @glog/log-graph
• p is a keyword naming a property of entry
• o is a value asserted for p s.t. [entry p o] in the log.

ontology clj/s

query-log clj/s

(query-log q)

(query-log g q)

Returns [bmap, ....] for q posed to optional g Where

• bmap := {var value, ...} bindings to q posed to g
• q is a query in a format amenable to g
• g is an IGraph supporting the graph-log vocabulary (default @log-graph)

remove-timestamps clj/s

(remove-timestamps)

(remove-timestamps g)

Spurious difference between two logs

remove-variant-values clj/s

(remove-variant-values)

(remove-variant-values g)

Returns g, removing/replacing values which would naturally vary between sessions. These would give rise to spurious differences between two otherwise identical logs. Timestamps are removed, and compiled objects are replaced with :compiled Where

• g is an optional log-graph from the current or past sessions. Default is current @log-graph

report-divergence clj/s

(report-divergence g1 g2)

search clj/s

(search inc-or-dec entry-test g c found q)

Returns [c found [previous-index]] for entry-test of ith entry per q and inc-or-dec See also the IGraph docs for traversal functions.

Where

• c is the (ignored) traversal context
• found is nil or the first previous entry to pass test
• previous-index decrements the head of q, or empty if found or i < 0
• entry-test := fn [g entry] -> boolean
• q := [entry or i [i] if still searching or [] if found. inc/dec-ing per iteration
• i is the execution order to test
• inc-or-dec :~ #{inc dec}, inc to search forward dec to search backward.
• entry is the ith entry in g
• g is a log-graph.
• NOTE: typically this is used as a partial application over test (igraph/traverse log (partial search-backward test) nil [entry-id])

search-backward clj/s

(search-backward test)

(search-backward test start)

(search-backward g test start)

Searches the log backward for a match to test, starting at start Where

• test := fn [g entry] -> boolean

• g is the log-graph

search-forward clj/s

(search-forward test)

(search-forward test start)

• start is an integer indexing (entries g) (default 0)
• g is the log-graph

set-level! clj/s

(set-level! element level)

Side-effect, adds args to entry for element in log-graph Where

• args := [predicate object, ...]
• element is an element of the log-graph

show clj/s

(show entry-id)

(show entry-id p)

(show entry-id p o)

• entry-id is the KWI of an entry
• g is a log-graph (default @log-graph)

std-logging-message clj/s

(std-logging-message & args)

Returns: a string suitable for standard logging based on args, or nil if there is no :glog/message specification. Where

• args := {p o, ....}
• p is a keyword naming a property, possibly :glog/message
• o is a value, known as template if p = :glog/message
• template is a mustache-style template to which desc-map will be applied Of the form `yadda {{<p>}} yadda...'
• desc-map := {p o, ...}, minus any :glog/message. Specifying o's to be inserted into template.
