Workspace utilities for developers
Contains routines for summarizing and searching the contents of a workspace.
Summarization routines list the names of objects of particular classes (functions, variables, or tables), or provide a type- dependent synopsis of their properties. Names can be specified either explicitly or by referencing a parent namespace (in which case all objects in all namespaces below it are considered). Object size is approximated and does not include attribute overhead.
The summarization routines are listed below.
| Name and Syntax | Description |
|---|---|
.ws.fns[names] |
Displays the names of functions contained in the specified namespaces, or in all namespaces if the argument is ` |
.ws.vars[names] |
Displays the names of variables (excluding tables) contained in the specified namespaces, or in all namespaces if the argument is ` |
.ws.tbls[names] |
Displays the names of tables contained in the specified namespaces, or in all namespaces if the argument is ` |
.ws.fnsum[names] |
Summarizes functions in the argument, expanding namespaces as appropriate. If the argument is `, all functions in all namespaces are included. The function summary includes the function name, its parameter list, line count, and size |
.ws.varsum[names] |
Summarizes variables (excluding tables) in the argument, expanding namespaces as appropriate. If the argument is `, all variables in all namespaces are included. The variable summary includes the variable name, its type, rank, size, and shape. Type is represented by the Q type character, with uppercase indicating a nonscalar value (e.g. a vector or higher-dimensional array); l and L indicate an enumerated value, Y a dictionary, and - a heterogeneous object. Rank is the number of leading uniform axes (where a scalar is 0) |
.ws.tblsum[names] |
Summarizes tables in the argument, expanding namespaces as appropriate. If the argument is `, all tables in all namespaces are included. The table summary includes the table name, its type, keys, row count, column count, and size. Type is M for an in-memory table, S for a splayed table, or P for a partitioned table |
fnsum, varsum, and tblsum return keyed tables as results so that one can, for example, compare two samples.

Searching routines provide a way to search functions within a workspace for one or more substrings. As with the summarization routines, names to search can be specified explicitly or by namepsace.
Searching can be either context-free or context-sensitive.
Context-sensitive searches treat certain constructs as
syntactic elements; these constructs are identifier names,
numeric constants (e.g. 1, -0.5, 1b), symbols (e.g. `price),
and character constants (e.g. "Error"). Context-sensitive
searching allows a match of a syntactic element only if the
entire element is matched.
Hits are reported by displaying the entire line on which a
match occurred, with a caret (^) pointing to the first
character of each match on the line. Results are written to
stdout.
The searching routines are listed below.
| Name and Syntax | Description |
|---|---|
.ws.fnshow[names;strs] |
Searches the specified functions or namespaces for one or more strings |
.ws.seshow[names;strs] |
Searches the specified functions or namespaces for one or more strings, matching only syntactic elements |
On the line below, the following syntactic matches are found:
a+b;"a+b";a_b:1;1_b;-1_-1,b;abc-1;101b;4+1 2 3i-1;1i_b;`bid
