In some embodiments, calculating the variable expression in the variable text to cause the replacement element to replace the variable expression, generating text corresponding to the replacement element, includes: traversing the variable text, searching the identification of the variable expression, and determining the position of the variable expression; and executing a replacing instruction corresponding to the variable expression, replacing a replacing element corresponding to the variable expression to the position of the variable expression, and generating a text corresponding to the replacing element.
The variable expression represents the incidence relation between the variable element and the replacement element, and corresponds to a section of program, and the section of corresponding program is a replacement instruction corresponding to the variable expression. There are special identifiers, such as "$" symbols, before and after the position of the variable expression, and before and after the position of the variable expression corresponding to the program. The variable expressions are located in the variable file, one or more variable expressions may be located in the variable file, the variable text may be traversed, the positions of the variable expressions in the variable text are determined by searching the identifications of the variable expressions, and the searched variable expressions are calculated. The calculation process is to execute a replacing instruction, replace the corresponding replacing element to the position of the variable expression, and generate the text corresponding to the replacing element.
Specifically, the above process of calculating the variable expression and replacing the variable expression with the replacement element can be illustrated as follows. And executing the replacement instruction corresponding to the variable expression, namely calculating the variable expression, and finding the storage position of the replacement element in the calculation process. The positions of the variable elements and the positions of the replacement elements are in one-to-one correspondence, so that the storage positions of the replacement elements can be traversed according to the positions of the variable expressions, the determined corresponding replacement elements can be found, the replacement elements are replaced to the positions of the variable expressions, and texts corresponding to the replacement elements are generated; in some specific scenarios, it is necessary to continuously execute a replacement instruction of a certain variable expression to obtain different execution results, determine different positions of corresponding replacement elements, and replace the values of the positions of the corresponding replacement elements with the positions of the variable expression, so as to generate a text corresponding to the replacement elements.
Specifically, the variable expression corresponds to a program, and can represent the association relationship between the variable element and the replacement element. For example, a program corresponding to the variable page number expression is written according to the requirements of the user.
And the variable page number expression added with the page number is PageNumber, and the expression is embedded into the text to be processed to form the variable page number text. The front and back positions of the expression comprise an identifier symbol "$", the identifier symbol is found when the variable page text is traversed, the variable page expression is calculated, a replacement instruction is executed, the position of $ PageNumber $ is replaced by the value of the page, and the text corresponding to the page value is generated.
Specifically, the replacement element corresponding to the variable expression is replaced to the position of the variable expression, for example, the variable expression represents a behavior of referring to an external name database, the external name database is a preset name table, the corresponding variable expression is { name }, and the corresponding partial variable text is < text > $ { name } $. The alternate instruction is executed to determine the storage location of the external name database, and "{ name }" represents the value of the different locations using the "name" table in the external database. The replacing method can perform traversal replacement from the name value of the starting position of the external database, and can also select the name value of a certain position range of the external database for replacement. The position of the variable expression is the position of "$ { name } $", and the name value corresponding to the position is confirmed to be replaced on the position of the variable expression, so that the "{ name }" is changed into "zhang three", "lie four", and the like. Finally, the expression is replaced by the corresponding name replacing element, and then the text of < text > three hello </text >, "< text > li four hello </text >" and the like are obtained, and the text corresponding to the replacing name element is generated.
The embodiment can search the variable expression by traversing the text to be processed, and special symbols exist before and after the position of the variable expression, so that the variable expression can be conveniently searched and identified, the situation that the variable expression is not identified is reduced, and the requirement of a user can be met. The position of the variable expression in the text is determined, the variable expression is calculated, the replacement element is automatically replaced to the position of the variable expression, accurate positioning and replacement of the replacement element are achieved, time is saved, and therefore the efficiency of relevant work can be improved.
In some embodiments, the replacing the variable element with a variable expression includes: determining a type of the variable element; determining a variable expression of a corresponding type according to the type of the variable element; and replacing the variable elements with variable expressions of corresponding types.
And determining the type of the variable element according to the requirement of the user, and determining the variable expression of the corresponding type. Common types of variable expressions include referencing standard environment variables, referencing external databases, and executing standard functions, which may be preset for the system. For example, if the variable expression contains a pure letter form of "Name", and the "Name" is a preset standard environment variable, the standard environment variable is searched; if the variable expression contains a symbolic form of 'Name }', searching an external database; if the variable expression includes a function form of "func ()", a call to the relevant standard function is made. After the variable expression is determined, the variable expression is replaced to the position of the variable element.
In some specific embodiments, the corresponding variable expression type is a reference standard environment variable, for example, a page number is added, the corresponding variable expression type is determined as the reference standard environment variable according to the type of the variable element, the variable page number expression of the corresponding type is PageNumber, which represents the standard environment variable to which the page number is added at the corresponding position of the text, and the PageNumber is a preset page number variable. And after the variable page number expression is determined, replacing the variable page number expression to the position of the variable element.
Specifically, the reference standard environment variable may further include, for example, a standard environment variable that determines, according to a user's requirement, that the variable page number expression of the corresponding type is JobName and DateTime, and represents that the job name and the print time are added at a corresponding position of the text. "JobName" and "DateTime" are standard environment variables that are automatically set by the system. After the variable expression is determined, the variable expression is replaced to the position of the variable element.
In other specific embodiments, the corresponding variable expression type refers to an external database, for example, different names are added to the text, so as to achieve personalized customization. And determining the type of the corresponding variable expression as a reference external database according to the type of the variable element, wherein the variable expression of the corresponding type is { name }, "{ }" is a symbol for referring to a preset external database, and "name" is a preset external name database. After the variable expression is determined, the variable expression is replaced to the position of the variable element.
In other specific embodiments, the corresponding variable expression type is a function executing standard, for example, in an office scenario, it is often necessary to edit the number of a formal document, which is generally called document number marking. The processing system of the computer can preset a standard function, and can replace the variable expression by the value corresponding to the standard function by executing the replacement instruction of the variable expression, wherein the corresponding variable expression is printf ("% 05 d", counter (1,1,0)), "counter" is the standard function for calculating the marking number, the number value is accumulated and calculated, and the formatted 5-bit zero padding value can be formed by the "printf" standard function. After the variable expression is determined, the variable expression is replaced to the position of the variable element.
In the embodiment, the types of the variable elements are determined, different types of variable expressions can be determined, redundant calculation of the variable expressions is reduced, and the efficiency of replacing the variable expressions by the replacing elements is realized more efficiently.
In other embodiments, the variable text comprises: various preset page templates; the determining of the variable text comprises: determining a corresponding page template according to a user instruction; the calculating the variable expression in the variable text comprises: calculating the variable expression in the corresponding page template; the method further comprises the following steps: determining an application text;
and superposing the text corresponding to the replacing element with the application text according to the superposition mode selected by the user to generate an intermediate format text.
The variable text can comprise a plurality of page templates, and the page template is a special variable text and only comprises a corresponding variable expression. And determining an application text according to the user requirement, wherein the application text is the text needing to be added with the variable elements. And selecting a corresponding superposition mode according to the user requirement, wherein the superposition mode can be a mode that the page template is superposed with the application text in sequence, or a mode that the page template selects superposition with the application text in different ranges. And calculating the variable expression in the corresponding page template to generate a text corresponding to the replacement element, and overlapping the text corresponding to the replacement element with the application text according to the overlapping mode selected by the user to generate an intermediate format text.
Specifically, for example, a page template is created. Firstly, a blank page template is made, variable page elements are added to corresponding positions of an application text, the corresponding variable page expression is PageNumber, and the page template is generated. And executing a replacement instruction of the variable expression in the page template, adding the changed page numerical value to the blank text template, and generating a text corresponding to the replaced page element. And determining an application text according to the user requirement, and overlapping the text corresponding to the replacing page code element with the application text to generate an intermediate format text. The corresponding position of each page on the intermediate format text is automatically added with a page number value.
By manufacturing different types of page templates, the variable graph description method can be conveniently and quickly applied to a plurality of scenes, and compared with a method for specifically performing variable graph description on an application page, the method for manufacturing the page template can save a great amount of time and energy in the application process. And the user can simply make or modify the page template according to the self requirement, so that the user can be met more flexibly.
In other embodiments, further comprising: generating a replacement instruction corresponding to the variable expression by using a standard variable and a standard function preset by a system; the executing the replacement instruction corresponding to the variable expression includes: executing the standard function including the standard variable.
Some standard variables and standard functions preset by the system, for example, those related to print settings. The replacement instruction of the variable expression related to the standard variable and the standard function can be determined according to the requirement of a user. And executing the replacement instruction corresponding to the variable expression, wherein the replacement instruction comprises executing a standard function preset by a system or referring to a standard variable contained in the standard function.
The above embodiments may be exemplified, for example, by making a perforation stamp, where the perforation stamp refers to a stamp stamped on an edge of a group of continuous pages, and the stamp portion of each page is different. According to the number of pages and the page spacing set by a user, a program generates a variable expression for controlling the displayable part of the original seal on each page, so that the seal part of each page is variable. The key variable here is the page number. Such as needing to cover a saddle stitch seal on pages 1 and 2, the program will generate two crop frames for pages 1 and 2, and a variable expression of page number to select the crop frame for the current page. And determining the replacement instructions of the corresponding variable expressions as eq (PageNumber, 1) and eq (PageNumber, 2) by using the relevant standard environment variable and the relevant standard function preset by the system, wherein the eq is the standard function representing whether the two numbers are equal or not, and the PageNumber represents the standard environment variable automatically set by the system. And executing a replacing instruction corresponding to the variable expression, wherein the replacing instruction comprises executing an eq standard function preset by the system and a relevant standard environment variable.
Specifically, the above embodiment may be exemplified, for example, when the position of the replacement element is determined during printing, the origin of the coordinate system for positioning is at the lower left corner of the page, so that x and y are positioned with respect to the left and lower edges of the page, and "x =" 100 "represents 100 left from the page, and" y = "50" represents 50 lower from the page. However, for the page template, the page size during actual printing is uncertain, and if positioning is required according to the right side and the upper side of the page, a replacement instruction of a corresponding variable expression needs to be determined by using a standard environment variable and a standard function. The variable expression is sub (PageWidth, 100), where "sub" is a standard function representing a subtraction operation, and "PageWidth" is a standard environment variable representing the current page width. The whole expression represents "PageWidth-100", that is, the meaning 100 from the right of the page. And executing the replacement instruction corresponding to the variable expression, wherein the execution of the sub standard function preset by the system is included.
In the above embodiment, the replacement instruction of the variable expression is executed, the standard function and the standard variable preset by the system can be executed, the range of the replacement element of the replacement instruction is increased, and the practicability of the method is effectively improved.
