compr!
A list comprehension macro.
vec_of_strings!
A vector initialisation macro.
input(prompt: &str) -> String
Prompts the user for input and returns it as a string.
cls()
Clears the terminal window on some terminal emulators.
e.g. does not work with the Intellij terminal.
type_of<T>(_: &T) -> String
Returns the type of variable T.
unix_shell(x: &str)
Executes slices as unix shell commands.
-
Some shell commands will not work on all terminal emulators. (e.g. "clear" in the Intellij terminal).
-
Compound shell commands will not work properly (e.g. commands using the "&&" operator).
seed()
Seeds the pseudo-random number generator with unix time.
pseudo(x: i32, y: i32) -> i32
Generates a pseudo-random number between x and y.
remove_empty_strings(v: Vec<String>) -> Vec<String>
Removes all empty strings from a vector of strings.
nth_char(x: &str, n: usize) -> char
Returns the nth char (zero indexed) from a slice.
is_digits(x: &str) -> bool
Checks if a slice consists only of digits.
is_i32(x: &str) -> bool
Checks if a slice represents an i32 integer.
is_f64(x: &str) -> bool
Checks if a slice represents an f64 float.
is_number(x: &str) -> bool
Like the "is_f64" function, but with additional format restrictions.
to_i32(x: &str) -> i32
Converts a slice to an i32 integer.
to_f64(x: &str) -> f64
Converts a slice to an f64 float.
char_count(x: &str) -> usize
Counts the number of chars in a slice.
slice_count(x: &str, y: char) -> usize
Counts the number of substrings in a slice, as delimited by a given char.
word_count(x: &str) -> usize
Counts the number of words in a slice.
line_count(x: &str) -> usize
Counts the number of lines in a slice.
nth_slice(x: &str, y: usize, z: char) -> String
Returns the nth slice (zero indexed) from a larger slice, as delimited by a given char.
nth_word(x: &str, y: usize) -> String
Returns the nth word (zero indexed) from a slice.
nth_line(x: &str, y: usize) -> String
Returns the nth line (zero indexed) from a slice.
write_to_file(path: &str, data: &str)
Writes data to a file.
file_exists(path: &str) -> bool
Returns true if the file path exists.
append_to_file(path: &str, data: &str)
Appends data to a file.
delete_file(path: &str)
Deletes the file on the named path.
read_from_file(path: &str) -> String
Reads data from a file into a string.
-
These functions will not work on Windows.
-
Only ASCII characters will be displayed correctly in the virtual terminal.
-
These functions will not work properly on some terminal emulators (e.g. the IntelliJ terminal).
vt_open()
Opens the virtual terminal.
vt_close(x: &str)
Displays a message, then closes the virtual terminal on the next user key press.
vt_cursor_off()
Hides the virtual cursor.
vt_cursor_on()
Displays the virtual cursor.
vt_rows() -> i32
Returns the number of rows in the virtual terminal.
vt_columns() -> i32
Returns the number of columns in the virtual terminal.
vt_cls()
Clears the virtual terminal.
vt_key_i32() -> i32
Obtains an i32 integer from a virtual terminal key press.
vt_input(x: i32) -> String
Obtains user input as a string with no more than x chars.
vt_put_slice(x: &str)
Displays a slice in the virtual terminal.
vt_render_menu(menu: &mut [String], size: usize, count: usize)
A helper function called by vt_menu.
vt_menu(menu:&mut Vec<String>) -> usize
Returns a usize integer based on the user's selection from a menu.
vt_render_prompt(prompt:&str, buffer:&mut String, pos:usize)
A helper function called by vt_edit_prompt.
vt_edit_prompt(prompt:&str, buffer:&mut String, max:usize) -> String
Displays a prompt to the user with an existing buffer, which can be edited to return a new buffer.
