Abstract

A unique identifier of an expression which refers to a cell of a data sheet is stored in a repository. In an application comprising an operation based on evaluating the expression, the expression is indicated by the unique identifier. In response to detecting a write directed to the cell, a modified version of contents of the cell is stored without re-evaluating the expression. The expression is re-evaluated in response to determining that the operation of the application is to be implemented.

Claims19

Dependent claims

A system, comprising:

one or more computing devices of one or more network-accessible services;
wherein the one or more computing devices include instructions that upon execution on or across one or more processors cause the one or more computing devices to:
store a persistent representation of a first cell-based expression in a first repository, wherein the first cell-based expression is indicated at least in part by input obtained via an application authoring interface configured for authoring applications, wherein the first cell-based expression refers to one or more cells of a data sheet comprising a two-dimensional grid of cells, wherein contents of the data sheet are stored in a second repository, and wherein the persistent representation comprises a unique identifier assigned to the first cell-based expression;
deploy an application of the applications, the application distinct from and at least partially developed via the application authoring interface, to one or more execution platforms, wherein the application is distinct from the first repository and the second repository and is based at least in part on the input obtained via the application authoring interface that is distinct from the application, wherein in the application, a screen layout is configured to display a value based on evaluating the first cell-based expression, wherein the application utilizes the unique identifier to indicate an association between the screen layout and the first cell-based expression, and wherein the application does not indicate cell coordinates of the one or more cells of the data sheet;
in response to detecting a write directed to a first cell of the one or more cells referenced in the first cell-based expression stored in the first repository distinct from the application, store modified contents of the first cell without re-evaluating the first cell-based expression;
and
in response to a running instance of the application reaching an execution stage in which the value of the first cell-based expression is needed and based on use of the association between the screen layout and the first cell-based expression indicated by the unique identifier to identify the first cell-based expression,
(a) re-evaluate the first cell-based expression stored in the first repository using the modified contents of the first cell, and
(b) cause the value, based at least in part on the re-evaluation of the first cell-based expression, to be displayed in the screen layout associated with the first cell-based expression by the unique identifier.

6 more elements

A method, comprising:

performing, at one or more computing devices:
storing a unique identifier of a first expression in a repository, wherein the first expression is indicated at least in part by input obtained via an application authoring interface for authoring applications, and wherein the first expression refers to one or more cells of a data sheet comprising a two-dimensional grid of cells;
generating an application of the applications, the application distinct from the repository and the application authoring interface, wherein in output corresponding to a portion of the application, a value based at least in part on the first expression is presented, wherein the application does not indicate cell coordinates of the one or more cells of the data sheet, and wherein the application utilizes the unique identifier to indicate an association between the output and the first expression;
in response to detecting a write directed to a first cell of the one or more cells referenced in the first expression, storing a modified version of contents of the first cell without re-evaluating the first expression;
and
in response to the application reaching an execution stage in which the value based at least in part on the first expression is needed and based on use of the association between the output and the first expression indicated by the unique identifier to identify the first expression,
re-evaluating the first expression stored in the repository, and
causing the value, based at least in part on the re-evaluating of the first expression, to be presented in the output associated with the first expression by the unique identifier.

5 more elements

One or more non-transitory computer-accessible storage media storing program instructions that when executed on or across one or more processors cause one or more computer systems to:

store a unique identifier of a first expression in a repository, wherein the first expression is indicated at least in part by input obtained via an application authoring interface for authoring applications, and wherein the first expression refers to one or more cells of a data sheet comprising a two-dimensional grid of cells;
generate an application of the applications, the application distinct from the repository and the application authoring interface, wherein one or more operations of the application are based at least in part on a result of evaluating the first expression, wherein the application does not indicate cell coordinates of the one or more cells of the data sheet, and wherein the application utilizes the unique identifier to indicate an association between the one or more operations of the application and the first expression in response to detecting a write directed to a first cell of the one or more cells referenced in the first expression, store a modified version of contents of the first cell without re-evaluating the first expression;
and
in response to the application reaching an execution stage in which the result of evaluating the first expression is needed and based on use of the association between the one or more operations and the first expression indicated by the unique identifier to identify the first expression,
re-evaluate the first expression stored in the repository, and cause the one or more operations, based at least in part on said re-evaluate the first expression, to be performed.
