From 20d1a04f1af4d67583bfd97658447ee7a135dfad Mon Sep 17 00:00:00 2001 From: John Darrington Date: Tue, 7 Jul 2009 03:39:36 +0800 Subject: [PATCH] Recode strings when writing system files. The long variable names, variable labels and value labels are now converted from utf8 to the dictionary encoding when writing a system file. --- src/data/sys-file-writer.c | 26 ++++++++++++++++---------- 1 file changed, 16 insertions(+), 10 deletions(-) diff --git a/src/data/sys-file-writer.c b/src/data/sys-file-writer.c index 13dc2de6..3fed2e05 100644 --- a/src/data/sys-file-writer.c +++ b/src/data/sys-file-writer.c @@ -31,6 +31,7 @@ #include #include #include +#include #include #include @@ -94,9 +95,9 @@ struct sfm_writer static const struct casewriter_class sys_file_casewriter_class; static void write_header (struct sfm_writer *, const struct dictionary *); -static void write_variable (struct sfm_writer *, const struct variable *); +static void write_variable (struct sfm_writer *, const struct variable *, const struct dictionary *); static void write_value_labels (struct sfm_writer *, - struct variable *, int idx); + struct variable *, int idx, const struct dictionary *); static void write_integer_info_record (struct sfm_writer *); static void write_float_info_record (struct sfm_writer *); @@ -222,7 +223,7 @@ sfm_open_writer (struct file_handle *fh, struct dictionary *d, /* Write basic variable info. */ short_names_assign (d); for (i = 0; i < dict_get_var_cnt (d); i++) - write_variable (w, dict_get_var (d, i)); + write_variable (w, dict_get_var (d, i), d); /* Write out value labels. */ idx = 0; @@ -230,7 +231,7 @@ sfm_open_writer (struct file_handle *fh, struct dictionary *d, { struct variable *v = dict_get_var (d, i); - write_value_labels (w, v, idx); + write_value_labels (w, v, idx, d); idx += sfm_width_to_octs (var_get_width (v)); } @@ -420,7 +421,7 @@ write_variable_continuation_records (struct sfm_writer *w, int width) /* Write the variable record(s) for variable V to system file W. */ static void -write_variable (struct sfm_writer *w, const struct variable *v) +write_variable (struct sfm_writer *w, const struct variable *v, const struct dictionary *dict) { int width = var_get_width (v); int segment_cnt = sfm_width_to_segments (width); @@ -461,9 +462,11 @@ write_variable (struct sfm_writer *w, const struct variable *v) if (var_has_label (v)) { const char *label = var_get_label (v); - size_t padded_len = ROUND_UP (MIN (strlen (label), 255), 4); + char *l = recode_string (dict_get_encoding (dict), UTF8, label, -1); + size_t padded_len = ROUND_UP (MIN (strlen (l), 255), 4); write_int (w, padded_len); - write_string (w, label, padded_len); + write_string (w, l, padded_len); + free (l); } /* Write the missing values, if any, range first. */ @@ -505,7 +508,7 @@ write_variable (struct sfm_writer *w, const struct variable *v) Value labels for long string variables are written separately, by write_long_string_value_labels. */ static void -write_value_labels (struct sfm_writer *w, struct variable *v, int idx) +write_value_labels (struct sfm_writer *w, struct variable *v, int idx, const struct dictionary *dict) { const struct val_labs *val_labs; const struct val_lab **labels; @@ -524,13 +527,14 @@ write_value_labels (struct sfm_writer *w, struct variable *v, int idx) for (i = 0; i < n_labels; i++) { const struct val_lab *vl = labels[i]; - const char *label = val_lab_get_label (vl); + char *label = recode_string (dict_get_encoding (dict), UTF8, val_lab_get_label (vl), -1); uint8_t len = MIN (strlen (label), 255); write_value (w, val_lab_get_value (vl), var_get_width (v)); write_bytes (w, &len, 1); write_bytes (w, label, len); write_zeros (w, REM_RND_UP (len + 1, 8)); + free (label); } free (labels); @@ -774,11 +778,13 @@ write_longvar_table (struct sfm_writer *w, const struct dictionary *dict) for (i = 0; i < dict_get_var_cnt (dict); i++) { struct variable *v = dict_get_var (dict, i); + char *longname = recode_string (dict_get_encoding (dict), UTF8, var_get_name (v), -1); if (i) ds_put_char (&map, '\t'); ds_put_format (&map, "%s=%s", - var_get_short_name (v, 0), var_get_name (v)); + var_get_short_name (v, 0), longname); + free (longname); } write_int (w, 7); /* Record type. */ -- 2.30.2
