Help using variables

[Martin]

Hi,

Action Write to File can not directly insert a line on a specific line. You would have to split the file into a list of lines, insert the line and write the lines to a file again. You can find some examples of splitting a file into lines on the examples page.

You can also use the split mechanism to check if a text file contains a particular text on a line. Something like this should work in a condition Expression:

Code: Select all

text_file = "line1\nline2\nline3\nline4";
lines = split(text_file, "\\n");
line3=getElement(lines, 2);
contains(line3, "line");

The last line of condition Expression determines whether the condition is true or false.

Martin

Thanks Martin.

How can i get the value inside a text file and turn it into a global_variable to be used on other scripts?

Hi,

Use a global variable in action Init Variable Text File. The action could look like this: Init Variable Text File: /storage/emulated/0/file.txt to global_text_file
Other flows will have access to the global variable global_text_file as soon as the action is executed. It's usually better to read the contents of a file only into a local variable, especially when the text file is large.
Could you explain what you are trying to achieve, maybe there's a better solution to the problem?
