Package csv is part of the go-fastreport library, a pure Go port of FastReport .NET.

Types ¶
type CSVDataSource ¶
type CSVDataSource struct {
data.BaseDataSource
// contains filtered or unexported fields
}
CSVDataSource is a DataSource backed by a CSV file or string. The first row is treated as a header row by default (HasHeader = true).
func NewFromConnectionString ¶
func NewFromConnectionString(name, connectionString string) *CSVDataSource
NewFromConnectionString creates a CSVDataSource from a FastReport connection string (e.g. "CsvFile=/data.csv;Separator=,;FieldNamesInFirstString=true"). This mirrors the C# CsvDataConnection constructor + property setters pattern, where each property setter calls CheckForChangeConnection(builder) to normalise and persist the connection string.
func (*CSVDataSource) Comment ¶
func (c *CSVDataSource) Comment() rune
Comment returns the comment character.
func (*CSVDataSource) ConvertFieldTypes ¶
func (c *CSVDataSource) ConvertFieldTypes() bool
ConvertFieldTypes returns whether automatic type conversion is enabled.
func (*CSVDataSource) FilePath ¶
func (c *CSVDataSource) FilePath() string
FilePath returns the CSV file path.
func (*CSVDataSource) HasHeader ¶
func (c *CSVDataSource) HasHeader() bool
HasHeader returns whether the first row is treated as a header.
func (*CSVDataSource) Init ¶
func (c *CSVDataSource) Init() error
Init loads and parses the CSV, populating the in-memory row store.
func (*CSVDataSource) LazyQuotes ¶
func (c *CSVDataSource) LazyQuotes() bool
LazyQuotes returns whether relaxed quote parsing is enabled.
func (*CSVDataSource) Separator ¶
func (c *CSVDataSource) Separator() rune
Separator returns the column delimiter.
func (*CSVDataSource) SetCSV ¶
func (c *CSVDataSource) SetCSV(s string)
SetCSV sets a raw CSV string as the data source.
func (*CSVDataSource) SetComment ¶
func (c *CSVDataSource) SetComment(r rune)
SetComment sets the comment character (0 = disabled).
func (*CSVDataSource) SetConvertFieldTypes ¶
func (c *CSVDataSource) SetConvertFieldTypes(v bool)
SetConvertFieldTypes enables automatic type inference per column. When true, Init() will attempt to convert each column to int, float64, or time.Time — falling back to string — matching C# DetermineTypes logic. See csv_convert.go for the inference algorithm.
func (*CSVDataSource) SetFilePath ¶
func (c *CSVDataSource) SetFilePath(path string)
SetFilePath sets the CSV file path.
func (*CSVDataSource) SetHasHeader ¶
func (c *CSVDataSource) SetHasHeader(v bool)
SetHasHeader sets whether the first row is a header row (default: true).
func (*CSVDataSource) SetLazyQuotes ¶
func (c *CSVDataSource) SetLazyQuotes(v bool)
SetLazyQuotes enables relaxed quote parsing.
func (*CSVDataSource) SetSeparator ¶
func (c *CSVDataSource) SetSeparator(r rune)
SetSeparator sets the column delimiter rune (default: ',').
type ConnectionStringBuilder ¶
type ConnectionStringBuilder struct {
// contains filtered or unexported fields
}
func NewConnectionStringBuilder ¶
func NewConnectionStringBuilder(connectionString string) *ConnectionStringBuilder
func (*ConnectionStringBuilder) Codepage ¶
func (b *ConnectionStringBuilder) Codepage() int
func (*ConnectionStringBuilder) ConvertFieldTypes ¶
func (b *ConnectionStringBuilder) ConvertFieldTypes() bool
func (*ConnectionStringBuilder) CsvFile ¶
func (b *ConnectionStringBuilder) CsvFile() string
func (*ConnectionStringBuilder) CurrencyFormat ¶
func (b *ConnectionStringBuilder) CurrencyFormat() string
func (*ConnectionStringBuilder) DateTimeFormat ¶
func (b *ConnectionStringBuilder) DateTimeFormat() string
func (*ConnectionStringBuilder) FieldNamesInFirstString ¶
func (b *ConnectionStringBuilder) FieldNamesInFirstString() bool
func (*ConnectionStringBuilder) NumberFormat ¶
func (b *ConnectionStringBuilder) NumberFormat() string
func (*ConnectionStringBuilder) RemoveQuotationMarks ¶
func (b *ConnectionStringBuilder) RemoveQuotationMarks() bool
func (*ConnectionStringBuilder) Separator ¶
func (b *ConnectionStringBuilder) Separator() string
func (*ConnectionStringBuilder) SetCodepage ¶
func (b *ConnectionStringBuilder) SetCodepage(v int)
SetCodepage sets the Codepage property.
func (*ConnectionStringBuilder) SetConvertFieldTypes ¶
func (b *ConnectionStringBuilder) SetConvertFieldTypes(v bool)
SetConvertFieldTypes sets the ConvertFieldTypes property.
func (*ConnectionStringBuilder) SetCsvFile ¶
func (b *ConnectionStringBuilder) SetCsvFile(v string)
SetCsvFile sets the CsvFile property.
func (*ConnectionStringBuilder) SetCurrencyFormat ¶
func (b *ConnectionStringBuilder) SetCurrencyFormat(v string)
SetCurrencyFormat sets the CurrencyFormat locale property.
func (*ConnectionStringBuilder) SetDateTimeFormat ¶
func (b *ConnectionStringBuilder) SetDateTimeFormat(v string)
SetDateTimeFormat sets the DateTimeFormat locale property.
func (*ConnectionStringBuilder) SetFieldNamesInFirstString ¶
func (b *ConnectionStringBuilder) SetFieldNamesInFirstString(v bool)
SetFieldNamesInFirstString sets the FieldNamesInFirstString property.
func (*ConnectionStringBuilder) SetNumberFormat ¶
func (b *ConnectionStringBuilder) SetNumberFormat(v string)
SetNumberFormat sets the NumberFormat locale property.
func (*ConnectionStringBuilder) SetRemoveQuotationMarks ¶
func (b *ConnectionStringBuilder) SetRemoveQuotationMarks(v bool)
SetRemoveQuotationMarks sets the RemoveQuotationMarks property.
func (*ConnectionStringBuilder) SetSeparator ¶
func (b *ConnectionStringBuilder) SetSeparator(v string)
SetSeparator sets the Separator property.
func (*ConnectionStringBuilder) String ¶
func (b *ConnectionStringBuilder) String() string
String serialises the builder back to a FastReport connection string. Mirrors C# CsvConnectionStringBuilder.ToString() used by CheckForChangeConnection. Only keys that have been explicitly set are included.
