scols_copy_table ()

struct libscols_table *
scols_copy_table (struct libscols_table *tb);

Creates a new independent table copy, except struct libscols_symbols that are shared between the tables.

scols_new_table ()

struct libscols_table *
scols_new_table (void);

scols_ref_table ()

void
scols_ref_table (struct libscols_table *tb);

Increases the refcount of tb .

                        struct libscols_column *cl);

Adds cl to tb 's column list.

scols_table_add_line ()

int
scols_table_add_line (struct libscols_table *tb,
                      struct libscols_line *ln);

Note that this function calls scols_line_alloc_cells() if number of the cells in the line is too small for tb .

scols_table_colors_wanted ()

int
scols_table_colors_wanted (struct libscols_table *tb);

scols_table_enable_ascii ()

int
scols_table_enable_ascii (struct libscols_table *tb,
                          int enable);

The ASCII-only output is relevant for tree-like outputs. The library checks if the current environment is UTF8 compatible by default. This function overrides this check and force the library to use ASCII chars for the tree.

If a custom libcols_symbols are specified (see scols_table_set_symbols() then ASCII flag setting is ignored.

scols_table_enable_colors ()

int
scols_table_enable_colors (struct libscols_table *tb,

int
scols_table_enable_maxout (struct libscols_table *tb,
                           int enable);

The extra space after last column is ignored by default. The output maximization use the extra space for all columns.

scols_table_enable_noheadings ()

int
scols_table_enable_noheadings (struct libscols_table *tb,
                               int enable);

Enable/disable header line.

scols_table_enable_raw ()

int
scols_table_enable_raw (struct libscols_table *tb,
                        int enable);

Enable/disable raw output format. The parsable output formats (export and raw) are mutually exclusive.

struct libscols_line *
scols_table_get_line (struct libscols_table *tb,
                      size_t n);

This is a shortcut for

ln = scols_new_line(); scols_line_set_....(cl, ...); scols_table_add_line(tb, ln);

struct libscols_column *
scols_table_new_column (struct libscols_table *tb,
                        const char *name,
                        double whint,
                        int flags);

This is shortcut for

cl = scols_new_column(); scols_column_set_....(cl, ...); scols_table_add_column(tb, cl);

The column width is possible to define by three ways:

whint = 0..1 : relative width, percent of terminal width

whint = 1..N : absolute width, empty colum will be truncated to the column header width

whint = 1..N

The column is necessary to address by sequential number. The first defined column has the colnum = 0. For example:

scols_table_new_column(tab, "FOO", 0.5, 0); // colnum = 0 scols_table_new_column(tab, "BAR", 0.5, 0); // colnum = 1 . . scols_line_get_cell(line, 0); // FOO column scols_line_get_cell(line, 1); // BAR column

scols_table_new_line ()

struct libscols_line *
scols_table_new_line (struct libscols_table *tb,
                      struct libscols_line *parent);

This is shortcut for

ln = scols_new_line(); scols_table_add_line(tb, ln); scols_line_add_child(parent, ln);

                       struct libscols_line **ln);

Finds the next line and returns a pointer to it via ln .

scols_table_reduce_termwidth ()

scols_table_remove_column ()

int
scols_table_remove_column (struct libscols_table *tb,
                           struct libscols_column *cl);

Removes cl from tb .

scols_table_remove_columns ()

int
scols_table_remove_columns (struct libscols_table *tb);

Removes all of tb 's columns.

scols_table_remove_line ()

int
scols_table_remove_line (struct libscols_table *tb,
                         struct libscols_line *ln);

Note that this function does not destroy the parent<->child relationship between lines. You have to call scols_line_remove_child()

scols_table_remove_lines ()

void
scols_table_remove_lines (struct libscols_table *tb);

This empties the table and also destroys all the parent<->child relationships.

scols_table_set_column_separator ()

int
scols_table_set_column_separator (struct libscols_table *tb,
                                  const char *sep);

Sets the column separator of tb to sep . Please note that sep should always take up a single cell in the output.

scols_table_set_line_separator ()

int
scols_table_set_line_separator (struct libscols_table *tb,
                                const char *sep);

int
scols_table_set_symbols (struct libscols_table *tb,
                         struct libscols_symbols *sy);

Add a reference to sy from the table. The symbols are used by library to draw tree output. If no symbols are specified then library checks the current environment to select ASCII or UTF8 symbols. This default behavior could be controlled by scols_table_enable_ascii().

scols_sort_table ()

int
scols_sort_table (struct libscols_table *tb,
                  struct libscols_column *cl);

Orders the table by the column. See also scols_column_set_cmpfunc().

scols_unref_table ()

void
scols_unref_table (struct libscols_table *tb);

Decreases the refcount of tb . When the count falls to zero, the instance is automatically deallocated.
