log_viewer_load.c File Reference

The log viewer's loading: a file the browse view opens is analysed (its delimiter, decimal convention and time column, see shared/logfile), its chosen columns are read, and lv_compute_spans() turns them into the plot's scaled traces; a report is read whole into the TEXT view. log_viewer_screen.c holds the state, the card's listing and paging and the screen's interface (log_viewer_screen.h); log_viewer_int.h is what the screen's four files share.

Functions
static const char *	err_text (log_err_t err)

	Returns a delimiter's name in the language showing.
static bool	open_name (log_source_t *src)
	The open file again: from the mount its page was read from, or not at all, so a list read since from another card lends it no file.
void	lv_run_analysis (void)
	Analyses the open file with the chosen delimiter and number convention, keeping the picked columns by name.
void	lv_compute_spans (void)
	Reduces the window's samples to a minimum and maximum row per pixel column and series, and the series' ranges.
void	lv_load_data (void)
	Loads the picked columns of the open file into the plot's samples.
static void	open_text (void)
	Read the report s.name names into the TEXT view and show it.
void	lv_open_selected (void)
	Opens the selected row: a CSV file to the import view, a report to the TEXT view; a folder or an oversized file is refused with a message.

Detailed Description

The log viewer's loading: a file the browse view opens is analysed (its delimiter, decimal convention and time column, see shared/logfile), its chosen columns are read, and lv_compute_spans() turns them into the plot's scaled traces; a report is read whole into the TEXT view. log_viewer_screen.c holds the state, the card's listing and paging and the screen's interface (log_viewer_screen.h); log_viewer_int.h is what the screen's four files share.

Function Documentation

err_text()

const char * err_text ( log_err_t err )

static

The reader's verdict in the language showing; log_err_str() is the English the console logs.

Parameters

err	the verdict

Returns

the words, from the text table

lv_delim_text()

const char * lv_delim_text

(

char

delimiter

)

Returns a delimiter's name in the language showing.

Parameters

delimiter

';', ',', tab or '|'

Returns

the name, "?" for any other

lv_message()

const char * lv_message	(	char *	buf,
		size_t	n )

Word the footer message into buf (log_viewer_int.h).

The footer message in the language showing.

Word the footer message into buf (log_viewer_int.h).

Parameters

buf	takes the message; never NULL
n	bytes at buf, 1 or more, LV_MSG_MAX for the longest

Returns

buf, "" for no message

lv_quiet()

void lv_quiet

(

void

)

Clear the footer message (log_viewer_int.h).

The footer message says nothing.

Clear the footer message (log_viewer_int.h).

lv_say()

void lv_say	(	ui_text_id_t	id,
		const char *	name )

Keep id and name as the footer message (log_viewer_int.h).

The footer message says id, a refusal or a failure.

Keep id and name as the footer message (log_viewer_int.h).

The message keeps the ID and the name, and lv_message() words it in the language showing, so a change of SET_LANGUAGE rewords it.

Parameters

id	the text: LOG_CANNOT_OPEN, LOG_IS_FOLDER, LOG_TOO_BIG, LOG_CANNOT_DELETE and LOG_DELETED format name; any other is shown as it is
name	the file's name, or NULL

lv_say_err()

void lv_say_err

(

log_err_t

err

)

Keep err as the footer message (log_viewer_int.h).

The footer message says the reader's verdict err, a failure.

Keep err as the footer message (log_viewer_int.h).

Parameters

err	the verdict of log_csv_analyse(), log_csv_build() or log_text_load()

open_text()

void open_text ( void )

static

Read the report s.name names into the TEXT view and show it.

The file is read once, whole, up to LOG_TEXT_MAX bytes; a file the I/O does not open, or one that fails to read, stays on the list with the reason in the footer.
