# ida_lines

High level functions that deal with the generation of the disassembled text lines.

This file also contains definitions for the syntax highlighting.
Finally there are functions that deal with anterior/posterior user-defined lines.

## Functions Overview

- `tag_strlen(line: str) -> ssize_t`: Calculate length of a colored string This function computes the length in unicode codepoints of a line
- `calc_prefix_color(ea: ida_idaapi.ea_t) -> color_t`: Get prefix color for line at 'ea'
- `calc_bg_color(ea: ida_idaapi.ea_t) -> bgcolor_t`: Get background color for line at 'ea'
- `add_sourcefile(ea1: ida_idaapi.ea_t, ea2: ida_idaapi.ea_t, filename: str) -> bool`
- `get_sourcefile(ea: ida_idaapi.ea_t, bounds: range_t = None) -> str`

- `install_user_defined_prefix(*args) -> bool`
- `add_extra_line(*args) -> bool`
- `add_extra_cmt(*args) -> bool`
- `add_pgm_cmt(*args) -> bool`
- `generate_disasm_line(ea: ida_idaapi.ea_t, flags: int = 0) -> str`
- `get_first_free_extra_cmtidx(ea: ida_idaapi.ea_t, start: int) -> int`
- `update_extra_cmt(ea: ida_idaapi.ea_t, what: int, str: update_extra_cmt.str) -> bool`

- `create_encoding_helper(*args) -> encoder_t *`
- `tag_remove(nonnul_instr: str) -> str`: Remove color escape sequences from a string.
- `tag_addr(ea: ida_idaapi.ea_t) -> str`: Insert an address mark into a string.
- `tag_skipcode(line: str) -> int`: Skip one color code. This function should be used if you are interested in color codes and want to analyze all of them. Otherwise tag_skipcodes() function is better since it will skip all colors at once. This function will skip the current color code if there is one. If the current symbol is not a color code, it will return the input.
- `tag_skipcodes(line: str) -> int`: Move the pointer past all color codes.
- `tag_advance(line: str, cnt: int) -> int`: Move pointer to a 'line' to 'cnt' positions right. Take into account escape sequences.
- `generate_disassembly(ea, max_lines, as_stack, notag, include_hidden: Boolean = False)`: Generate disassembly lines (many lines) and put them into a buffer
- `requires_color_esc(c)`: Is the given char a color escape character?
- `COLSTR(str, tag)`: Utility function to create a colored line
